Material characteristics: wear-resistant, impact-resistant, self-lubricating, corrosion-resistant, impact absorption, low temperature resistance, hygienic and non-toxic, not easy to adhesion, not easy to absorb water, low density.
Molecular weight: more than 3 million
The roller surface material is the raw meal extruded ultra-high molecular weight polyethylene pipe independently produced by our factory, which is more excellent than conventional products in terms of wear resistance, corrosion resistance, non-adhesion and self-lubrication.
Supply commitment: guarantee the material and guarantee the molecular weight.
1.Different from metal rollers, we use ultra-high molecular weight polyethylene (UHMW-PE), which has the most superior mechanical and physical properties among engineering plastics, as the material to make the roll surface and seat cover. Compared with traditional materials, it has outstanding advantages in performance.First, the molecular structure of ultra-high molecular weight polyethylene is a winding linear arrangement, so its impact strength is extremely high, European and American countries have long used this material in body armor and armor protection, China has been developing and applying ultra-high materials in recent years to gradually replace bulky metal materials. Acting on the roller, it will not break due to long-term rotation, drop or impact.
2, the friction coefficient of ultra-high molecular weight polyethylene products is extremely small, which is similar to the ice surface. As the surface of the roller, it can effectively reduce the friction with the belt surface, thereby prolonging the service life of the belt.
3, ultra-high molecular weight polyethylene has excellent wear resistance, which is the best wear resistance among all engineering plastics. Experimental data show that under relative conditions, it is 5-7 times more resistant to wear than carbon steel or stainless steel. This alone extends its service life by more than three times longer than that of steel rollers.
4, the corrosion resistance of ultra-high molecular weight polyethylene is excellent. At room temperature, it is difficult for any concentration of acid, alkali, salt, sulfur and other corrosive media to produce chemical reaction with it. As an idler, you don't have to worry about corrosion, rust.
5, the water absorption rate of ultra-high molecular weight polyethylene is extremely low (0.01%), so its own anti-adhesion is excellent, even under water or oil medium, dust will not stick to its surface and scale. As an idler, there is no need to worry about biting the belt on the surface due to the adhesion of materials, and there is no need to worry about increasing the rotational resistance due to scaling of the rotating part.
6, the specific gravity of ultra-high molecular weight polyethylene is very light, only about 0.94, which is 1/8 of carbon steel. As an idler, it is easy to install and replace and operate without noise, which reduces the working intensity and purifies the working environment.
7. Ultra-high molecular weight polyethylene rollers can have bispecific antibody (antistatic, halogen-free flame retardant) characteristics (MT558.1-2005), which can be used in special environments such as coal mines, and the safety can be guaranteed.
