Polyethylene is wear-resistant, light in weight, convenient in construction, beautiful, compressive, impact resistant, non-hygroscopic, easy to clean, non-toxic and tasteless, and can replace steel materials. It is a new type of engineering plastics.
Characteristics of polyethylene trench cover:
1. High wear resistance: static friction coefficient is 0.07;
2. Self-lubrication: smooth surface without roughness;
3. Impact resistance: good impact resistance without damage;
4. Corrosion resistance: resistant to acid and salt corrosion;
5. Non-adhesiveness: low surface tension, not easy to scale;
6. Anti-static property: anti-static coefficient 10 to the power of 3 to 6;
7. UV protection: effectively extend the service life of the product;
8. Raw and non-toxic: odorless, non-toxic, odorless, non-corrosive, and can be used to contact with food;
9. Light weight: the density is 0.93-0.97, and the texture is light;
10. Anti aging: no aging for 50 years under normal sunshine conditions.
The polymer sewer cover plate is used in different places such as slaughterhouses, food factories, antiseptic workshops, municipal and government roads, garden facilities, residential areas, schools and stadiums.
