Polishing Wax/polish compound/polish paste belongs to chemical products and commodities, but in fact it is made by physical mixing and heating. Polishing wax also produces grinding, smoothing, smooth, and bright effects through physical movement during use, thereby playing the role of polishing and polishing. Polishing wax has a wide range of uses. It not only refers to the polishing and polishing of metals, but also the polishing of resins PU,PA, plastics, as well as hardwood furniture and appliances.
Polishing is divided into rough polishing, medium polishing, fine polishing and mirror polishing.For metal utensils and utensils of different materials, it is necessary to choose a suitable polishing wax to play a real role and an ideal effect.

Analyze the technical innovation and industrialization of anti-seepage fiber
The fundamental performance requirements for textiles are “thermal protection†and “coverage.†The term “coverage†refers to the ability of a fabric to visually obscure the body, preventing transparency. Dark and heavy fabrics generally do not have visibility issues, but light-colored fabrics—especially white ones—commonly used in undergarments or for skin exposure can lead to inappropriate appearances. To address this, the Quartermaster Equipment Research Institute under the General Logistics Department has developed anti-transparency fibers suitable for summer light-colored and thin clothing. This innovation not only solves the issue of visibility but also brings real economic benefits through collaboration between research, education, and production.
The institute, along with its partners, has introduced a multi-scattering approach to improve the visibility of light-colored, lightweight fabrics that often reveal undergarments or skin, causing an unseemly appearance. By combining anti-transparent polyester fibers with two-component elastic anti-permeability fibers, they achieved a double-layer visual shielding effect, surpassing traditional fabric standards. These fibers offer excellent coverage without compromising comfort, solving the long-standing international problem of poor visual obscuration in light-colored fabrics.
Four key breakthroughs were made in the development of these fibers:
1. **Scientific Theories on Visual Obscuration**: The research established a theoretical relationship between textile visual obscuration and material properties, structural parameters, and environmental factors. It was found that light and light-colored fabrics cannot rely on absorption or thickness; instead, internal light scattering within reinforced fibers is the most effective method. This led to the development of complex fiber cross-sections with multiple scattering paths, surface roughening, and porous yarn structures to enhance light-blocking effects.
2. **Mie Scattering Theory Application**: For the first time, Mie scattering theory was used to calculate the scattering behavior of high-refractive-index powders. After testing various particle sizes and refractive indices, it was determined that TiOâ‚‚ particles between 278 nm and 571 nm provided optimal anti-seepage performance. This was applied to polyester and elastic anti-transparent fibers, significantly improving their effectiveness.
3. **Development of Anti-Transparent Fibers and Fabrics**: Innovative fiber designs with 8 thin-walled diaphragms, 16 macro-reflective interfaces, and numerous micro-reflective surfaces were created. These structures allowed light to be scattered and absorbed effectively, reducing transparency while maintaining softness and comfort. These fibers were used in blended fabrics such as wool-cotton and produced in large quantities for military, industrial, and sportswear applications.
4. **Visual Obscuration Evaluation Method**: A new evaluation system was introduced, considering both light energy permeability and imaging ability. This standard enabled quick and accurate assessment of fabric opacity, particularly useful for military uniform materials.
Anti-transparency fabric development is now critical. Many navies use heavy fabrics in summer to avoid transparency, but this reduces comfort. Lighter fabrics often fail to provide adequate coverage, affecting military appearance. China’s previous navy uniforms required lining or additional garments to prevent exposure, which compromised comfort. Thus, there was a need for a fabric that is both thin and opaque, combining visual obscuration with comfort.
According to Shi Wei, a senior engineer at the Military Equipment Research Institute, Chinese naval personnel face challenges in balancing aesthetics and functionality. Compared to foreign counterparts, Chinese sailors may lack resistance to sun and humidity, making the need for anti-fluoroscopy fabric even more urgent.
Through collaboration between industry, academia, and the military, the project has yielded significant results. In 2007, new military uniforms were introduced using this technology, including navy white summer uniforms and spring/fall fabrics. These fabrics successfully concealed undergarments while maintaining breathability and comfort. The technology has been widely adopted across the military and is expected to expand into public security sectors.
Currently, anti-fluoroscopy fabrics are primarily sold domestically. With technological advancements, the fabric also offers UV and heat resistance. Studies show that anti-fluoroscopy fabric heats up more slowly and remains about 5°C cooler than regular fabric.
Research and development efforts continue, with institutions like Donghua University and the General Armament Equipment Research Institute playing key roles. Wang Ni, an associate professor at Donghua University, highlighted the importance of optimizing powder size for maximum effectiveness, avoiding issues related to nano-scale particles.
Companies like Zhoushan Xinxin Chemical Fiber Co., Ltd., Zhejiang New Textile Co., Ltd., and Jiangsu Sunshine Group have played major roles in commercializing the technology. Their products have been widely used in military and civilian applications, contributing millions in revenue.
Internationally, the fabric has gained traction in the Middle East and Africa, where it is valued for its comfort and durability. Orders for Arab robes and military uniforms have increased, demonstrating the global potential of this innovative textile technology.
