Non-toxic surfactants represent a vital green alternative to traditional petroleum-based surfactants widely used across industries. Like conventional surfactants, they feature amphipathic molecular structures that reduce water surface tension, delivering reliable functions including cleansing, emulsification, wetting and foaming. The core difference lies in their safety profile and environmental compatibility, as they avoid harsh irritants, persistent pollutants and harmful by-products common in synthetic counterparts.
Most non-toxic surfactants are derived from renewable feedstocks such as plant oils, glucose, amino acids, or produced via microbial fermentation. Typical examples include alkyl polyglucosides, amino acid-based surfactants and glycolipid biosurfactants. These materials show low skin and eye irritation, making them suitable for sensitive-skin cosmetics, baby care formulas and oral care products. They are readily biodegradable in aquatic environments and will not accumulate in soil or water ecosystems after discharge.
Their industrial applications keep expanding beyond personal care. Non-toxic surfactants serve in food processing, pharmaceutical formulation, agricultural adjuvants and environmental remediation such as oil spill treatment. They maintain stable performance under hard water and varied temperature conditions, balancing practical efficiency with regulatory safety requirements.
As global regulations tighten on chemical discharge and consumers prioritize green products, non-toxic surfactants become a key component of sustainable chemistry. Ongoing research focuses on lowering production costs and boosting yield, to accelerate the replacement of toxic surfactants. They help manufacturers reduce health risks for end users and cut the ecological footprint, supporting long-term industrial transition toward circular and low-hazard production.

Grounding solar panels an essential safety step for any photovoltaic installation, whether residential or commercial. It connects all exposed metal parts of the solar system, including panel frames, mounting racks, inverter housings and junction boxes, to the earth through conductive wires and grounding electrodes. This setup creates a low-resistance path to divert dangerous fault currents away from people and hardware during electrical failures or lightning surges.
Two main types of grounding apply to solar PV systems. Equipment grounding, the most common form, bonds all non-current-carrying metal components together. If electrical insulation breaks down and live wires touch metal frames, fault current flows safely into the ground instead of electrifying the structure. System grounding stabilizes DC voltage levels and helps ground-fault detectors quickly identify wiring faults. Without proper grounding, metal surfaces may become live, causing electric shocks, equipment burnout or even electrical fires.
Installers must follow local electrical codes such as NEC Article 690. Continuous bonding across the whole array is required to avoid disconnected segments. Copper conductors and grounding lugs are widely used to link panels and racks, which finally connect to ground rods or the building’s existing earth electrode system. Loose connections, corrosion or undersized grounding cables will weaken protection. Regular annual inspections help check for oxidation and loose torque on terminals.
Many people underestimate grounding and treat it as optional. Yet lightning strikes and insulation defects happen unexpectedly. A well-grounded solar array reduces surge damage to expensive inverters and modules, extending the service life of the whole system. For solar projects, reliable grounding is not merely a code requirement. It is the fundamental safeguard protecting property and lives while enabling stable, clean solar power operation.
Rubber floor mat is a common floor covering. Its anti-slip, waterproof and wear-resistant properties make it widely used in various occasions. However, many people have encountered the problem of pungent odor that comes with new rubber floor mats. This smell mainly comes from volatile organic compounds (VOCs) in rubber materials. Fortunately, there are some simple methods that can help us eliminate rubber floor mat smell, allowing us to take a deep breath and enjoy a comfortable living environment.
Method One: Cleaning and Ventilation
Take the rubber floor mat outdoors or to a well-ventilated area. Cleaning the floor mats thoroughly with detergent and water will remove some of the odor. Then dry the mat in a ventilated place to let the natural wind help the smell dissipate. Doing this will remove some chemical residue from the surface.
Method 2: Use natural adsorbents
Natural adsorbents such as activated carbon and baking soda can effectively adsorb volatile organic compounds. Place an appropriate amount of natural adsorbent next to the rubber floor mat or directly on the floor mat. Replace the adsorbent every once in a while to continue to absorb the odor emitted by the floor mat.
Method 3: Use desiccant
Place a small amount of desiccant such as dry garden plaster, silica gel, etc. near the rubber floor mat to absorb moisture from the floor mat and reduce the odor caused by moisture. At the same time, they can also absorb some odor molecules and effectively remove the odor of rubber floor mats.
Method 4: Use deodorant and air freshener
There are many deodorizers and air fresheners for rubber materials on the market. Using these products can quickly remove the smell of rubber floor mats. Pay attention to choosing harmless and environmentally friendly products and use them correctly according to the instructions.
Method 5: Accumulation of time
Most rubber flooring odor problems will lessen over time. We can eliminate the odor by allowing the volatile organic compounds in the rubber floor mats to gradually evaporate through repeated cleaning, ventilation and daily use.
There are many ways to eliminate the smell of rubber floor mats. We can choose the appropriate method according to personal preferences and actual conditions. At the same time, choosing reliable and environmentally friendly rubber floor mats when purchasing can also reduce the generation of odors. No matter which method you use, remember to persist. The odor problem of rubber floor mats will eventually be eliminated, and we can enjoy a fresh and pleasant living environment.

When selecting a centrifugal fan, airflow, static pressure, efficiency and noise are usually the first parameters considered. Impeller material, however, is often reduced to a simple assumption: metal is stronger, while plastic is lighter.
In practice, impeller material affects structural strength, dimensional stability, manufacturing methods and environmental suitability. It should not be evaluated independently of blade geometry, impeller diameter, operating speed or temperature.
In this article, metal impellers mainly refer to the steel, aluminum-alloy and stainless-steel impellers commonly used in industrial centrifugal fans. Plastic impellers mainly refer to components made from glass-fiber-reinforced engineering plastics such as PA6-GF. Performance can vary significantly according to material grade, glass-fiber content and structural design. Final selection should therefore be based on the technical documentation and test results for the specific fan model.
Comparison of the structural and material characteristics of metal and engineering-plastic centrifugal impellers
Fire Safety: Material Properties Are Not the Same as Whole-Fan Fire Resistance
Under normal fan operating conditions, steel and aluminum-alloy impellers do not exhibit the softening and dripping behavior associated with thermoplastics. Their metallic base materials also do not produce smoke through the thermal decomposition of a polymer matrix.
Metal impellers can therefore offer a material-level advantage in applications where combustible materials are restricted, or where smoke generation and molten dripping are particular concerns.
A metal impeller, however, should not automatically be regarded as suitable for smoke extraction. At elevated temperatures, the mechanical strength of steel and aluminum alloys may decrease, and thermal deformation may occur. Surface coatings, motor insulation, bearing lubricants, cables and electronic controls must also be assessed for high-temperature operation.
Some engineering plastics can be compounded with flame retardants to achieve specified flammability ratings. These ratings describe how a standardized material specimen performs under defined test conditions. They do not, on their own, demonstrate that the complete fan is suitable for smoke extraction or has achieved a particular fire-resistance classification.
For smoke extraction, high-temperature air handling or applications with defined fire-resistance requirements, suitability should be determined through whole-fan testing at the specified temperature and duration, rather than by impeller material alone.
The fire safety and structural reliability of a metal impeller must be verified together with the complete fan under defined high-temperature test conditions
Structural Strength: Focus on Allowable Tip Speed and Long-Term Stability
At comparable temperatures and with appropriate structural design, metals generally offer a higher elastic modulus and better dimensional stability. This can provide greater design flexibility for larger impellers, higher allowable tip speeds and greater centrifugal loads.
Even so, the reliability of a metal impeller is not determined by material strength alone. Stamping, bending and welding may introduce local deformation or residual stress. Blade attachment points, weld quality and balancing accuracy can all affect long-term operation.
For high-speed impellers, structural safety margins may also need to be assessed through finite-element analysis, overspeed testing and fatigue validation.
Plastic impellers are commonly manufactured from glass-fiber-reinforced engineering plastics such as PA6-GF. Glass fibers can improve stiffness and mechanical strength, but actual performance depends on fiber content, fiber orientation, wall-thickness design, ambient humidity and molding conditions.
Injection molding allows blades, backplates and connecting structures to be formed as a single component, making complex three-dimensional blade geometries easier to produce. At the same time, designers must control molding shrinkage, warpage and anisotropic behavior caused by fiber orientation.
For impellers operating continuously at elevated temperatures or under sustained mechanical loads, creep and long-term material aging must also be considered.
Aerodynamic Performance: Blade Design Matters More Than Material Choice
The aerodynamic efficiency of a centrifugal fan is not determined directly by whether the impeller is made from metal or plastic.
Blade curvature, impeller diameter, blade count, inlet geometry, volute or airflow-path matching, and the clearance between the impeller inlet and inlet cone all influence flow separation, recirculation losses and pressure development.
Injection molding is well suited to complex surfaces and smooth geometric transitions. When tooling, material and processing conditions are stable, it can also provide consistent geometry across large production volumes. For this reason, molded plastic impellers are widely used in small and medium-sizedproduced in larger quantities.
Advances in metal forming and joining technologies have also made three-dimensional blade designs possible in metal impellers. Some product generations have improved efficiency, allowable speed and acoustic performance through optimized blade profiles, inlet matching and stress distribution.
These results, however, are usually associated with the development of specific products. They should not be interpreted as evidence that metal impellers are universally more efficient than plastic alternatives.
The two options should be compared under the same test standard and operating conditions, using airflow–static pressure curves, total or static efficiency, input power and sound power data.
Impeller material should be matched with the motor, airflow path, heat-exchange components and actual operating conditions
Noise and Vibration: Material Alone Does Not Determine Acoustic Performance
Engineering plastics generally provide greater material damping, while metals usually offer a higher elastic modulus. These characteristics can influence structural behavior, but neither directly determines the overall noise level of a fan.
The acoustic performance of a centrifugal fan is also affected by blade-pass frequency, flow separation, impeller balance, installation stiffness, structural modes and the selected operating point.
When a fan operates close to stall or near a structural resonance speed, noise and vibration may increase significantly even when the impeller material remains unchanged.
Statements such as “plastic impellers are always quieter” or “metal impellers are always more stable” are therefore too broad. Low-noise selection should be based on sound power data at the specified operating point, together with the operating-speed range and the airflow path inside the equipment.
Corrosion Resistance and Environmental Compatibility: Verify Material Suitability Case by Case
Plastic impellers do not suffer from conventional metallic oxidation or rust and generally require no additional anti-corrosion coating in ordinary humid environments.
However, plastic is not resistant to every medium. Oil mist, solvents, cleaning chemicals, ultraviolet exposure, high temperatures and high humidity can all affect material properties.
Metal impellers can be manufactured from galvanized steel, coated steel, aluminum alloy or stainless steel, depending on the operating environment. Corrosion resistance varies substantially between different metal grades and surface treatments.
Where salt spray, chemical gases or condensate may be present, material selection should be based on the actual medium and verified accordingly.
Manufacturing Cost: Production Volume and Size Determine Overall Value
Plastic impellers usually require a relatively high initial investment in injection-molding tools. Once stable mass production has been established, however, they can offer short molding cycles, fewer individual parts and good batch-to-batch consistency. This makes them well suited to small and medium-sized products manufactured in larger volumes.
Metal impellers may require cutting, forming, welding, surface treatment and balancing. Although this involves more individual processing steps, metal construction often provides greater flexibility for large impellers, special dimensions and low-volume customized projects.
Cost comparisons should therefore extend beyond the purchase price of a single impeller. Tooling investment, production volume, transport weight, maintenance conditions and expected service life should all be considered.
Selection Must Begin with the Actual Operating Conditions
When selecting an impeller material for a centrifugal fan, engineers should verify several key conditions:
Does the applicable equipment standard restrict combustible materials? What are the ambient temperature and conveyed-air temperature? What are the maximum operating speed and allowable impeller tip speed? Does the airstream contain moisture, salt spray, oil mist, dust or chemical substances? Will the fan operate continuously? What safety tests and market-access requirements must the complete fan satisfy?
Across its centrifugal fan range, Blauberg uses different impeller materials according to impeller diameter, operating speed and application environment. Model-specific documentation identifies parameters such as impeller material, motor protection, control options and performance data.
Some models use PA6-GF impellers, while others use metal impellers. The exact configuration and scope of protection should always be confirmed in the technical specification for the relevant model.
This product-development approach reflects an important principle: impeller material should be treated as one element of system selection and evaluated together with the motor, operating speed, airflow path, control method and application environment.
Metal impellers are often worth considering where equipment standards restrict combustible materials, where tip speeds are relatively high, or where dimensional stability is a priority.
Engineering-plastic impellers may be suitable where weight reduction, complex molded blade geometry and production consistency are important.
The comparison should not be viewed as a contest between a “higher-grade” and a “lower-grade” material. The better choice is the impeller that suits the operating conditions, has been properly validated and is correctly matched to the complete fan system.

Since the beginning of this year, China’s transformer industry has benefited from multiple structural growth drivers, including the global energy transition, the rapid expansion of AI infrastructure, and accelerating investment in power grids. As a result, both the value and volume of China’s transformer exports have increased by more than 40% year on year, maintaining a strong growth trajectory.
However, smaller and mid-sized transformer manufacturers continue to face challenges in expanding into overseas markets due to certification barriers, limited distribution channels, and relatively weak financial capabilities. Many of these companies remain more dependent on the domestic market or on subcontracting and secondary orders from larger exporters.
Copper and GOES Remain Key Cost Drivers for Transformers
Copper and grain-oriented electrical steel (GOES) are two of the principal raw materials used in transformer manufacturing. Copper typically accounts for more than 35% of total transformer costs, while electrical steel accounts for more than 25%. Consequently, fluctuations in the prices of these two materials have a significant impact on transformer manufacturing costs and overall profitability.
Since the fourth quarter of last year, copper prices have surged sharply, pushing up transformer prices as copper-intensive products became increasingly expensive to manufacture. By contrast, prices for GOES, another major transformer input, have remained relatively stable.
Industry sources indicate that the stability of electrical steel prices since the beginning of this year has provided transformer manufacturers with relatively favorable cost conditions and helped support their profit margins.
Strong Overseas Demand, but Limited Upside for High-Grade GOES
As grid modernization accelerates across Europe and the United States, demand for transformers in overseas markets has increased substantially. At the same time, however, a significant portion of overseas customers remains highly price-sensitive.
Although there appears to be limited room for further increases in the price of high-permeability grain-oriented electrical steel (Hi-B steel), prices have been raised by approximately RMB 100–200 per ton on a monthly basis since the beginning of this year. Even so, prices have yet to return to what would be considered a normal or sustainable level, and some products are reportedly still being sold at a loss.
Overseas Demand Structure Continues to Pressure GOES Prices
Demand patterns across different overseas markets have also contributed to pricing pressure on China’s electrical steel industry.
Customers in Africa and the Middle East tend to have stronger demand for conventional electrical steel grades and are less reliant on premium-grade grain-oriented electrical steel. This has increased price competition among Chinese transformer and electrical steel manufacturers, forcing producers to negotiate aggressively over raw-material costs.
This persistent price competition is considered one of the key reasons why GOES prices have remained under pressure despite growing transformer demand.
Another major factor is the rapid expansion of domestic GOES production capacity.
According to incomplete industry statistics, China’s effective GOES production capacity reached approximately 4.08 million tonnes in 2025, representing an increase of around 750,000 tonnes year on year. Total production reached approximately 3.45 million tonnes, up 13% year on year, of which grain-oriented electrical steel production accounted for approximately 2.96 million tonnes.
The continued expansion of domestic capacity has intensified competition among producers and limited the industry’s ability to pass higher costs through to downstream transformer manufacturers.
GOES Prices Could Enter a Gradual Recovery Cycle
Although GOES prices are currently near the bottom of the cycle, market conditions may gradually improve.
Industry analysts expect China’s GOES market to enter a period of range-bound consolidation with an upward bias in 2026, supported by increasing demand from both domestic and international power-grid investment.
The 14th Five-Year Plan’s successor planning cycle, commonly referred to as the “15th Five-Year Plan” (2026–2030), is expected to involve approximately RMB 4 trillion in power-grid investment. Meanwhile, grid modernization programs in the United States and Europe are expected to continue generating strong demand for transformers and related electrical steel products.
Market research suggests that new capacity coming online in 2026, together with increasing order volumes reported by operating producers, could support a gradual recovery in GOES prices.
There are already indications that power-grid projects under the 15th Five-Year Plan are moving into the implementation stage, with related orders beginning to enter the supply chain. Following the impact of the Chinese New Year holiday during the first quarter, a portion of these grid-investment projects is expected to enter the tendering phase from the second quarter onward.
The pace of project implementation appears to be faster than previously anticipated by the market, potentially providing additional support to transformer and electrical steel demand.
Transformer Demand Remains Strong Despite Weakness in Certain Domestic Segments
Since last year, demand for small- and medium-sized transformers from domestic EV charging stations has weakened noticeably. Nevertheless, industry participants remain broadly optimistic about China’s transformer market over the next two years.
The implementation of approximately RMB 4 trillion in planned grid investment is expected to generate substantial incremental demand for transformers. At the same time, China’s rapidly developing energy-storage sector and heavy-duty truck charging infrastructure are expected to create additional demand for conventional transformer products.
Overseas charging infrastructure is also entering a period of accelerated development, creating further opportunities for Chinese transformer manufacturers with established export capabilities.
In China, transformer replacement and upgrading programs in rural and township power networks are also expected to support demand for high-efficiency transformers over the coming years.
More importantly, the rapid expansion of AI data centers and high-performance computing (HPC) facilities has emerged as one of the most certain growth drivers for the transformer industry.
AI Data Centers Could Reshape the Future of Transformer Technology
In October 2025, NVIDIA presented an 800V DC power architecture white paper at the OCP Global Summit, outlining a potential roadmap for power delivery in next-generation AI data centers.
As AI infrastructure continues to scale, future data centers will require substantially higher power density, greater energy efficiency, and more intelligent power-management architectures. Against this backdrop, solid-state transformers (SSTs) are increasingly being considered as a potential long-term solution for next-generation AI factories.
In the longer term, solid-state transformers could gain significant market share in high-end applications such as renewable energy systems, data centers, and smart grids.
Several publicly listed companies have already begun investing in and accelerating the development of solid-state transformer technologies.
However, industry experts generally believe that conventional transformers will remain the dominant technology in data centers and AI computing facilities in the short term, primarily because the cost of solid-state transformers remains significantly higher than that of conventional transformer systems.
Therefore, while SSTs may represent the long-term technological direction of the industry, conventional transformers are still expected to account for the majority of near- to medium-term demand.
Outlook
Overall, China’s transformer and GOES industries are entering a period characterized by strong overseas demand, accelerating domestic grid investment, and rapidly expanding AI-related power infrastructure.
For the GOES market, the combination of China’s large production capacity and intense price competition continues to limit near-term pricing power. Nevertheless, the expected acceleration of domestic grid investment, together with sustained demand from the U.S. and European power-grid upgrade cycles, could gradually tighten the supply-demand balance.
For transformer manufacturers, meanwhile, the combination of grid modernization, renewable energy deployment, energy storage, EV charging infrastructure, and AI data centers is creating a broad-based demand cycle.
The key question for the GOES industry is therefore no longer whether transformer demand will grow, but rather how quickly incremental transformer demand will translate into additional demand for electrical steel and, ultimately, restore pricing power to upstream GOES producers.
