The distinction method of uhmw polyethylene sheet
Good performance of uhmw polyethylene sheet：
Ultra-high molecular weight polyethylene sheet is more and more widely used in industry, mining, gardening, medicine and other fields, because ultra-high molecular weight sheet has high wear resistance, corrosion resistance, impact resistance, self-lubrication and other characteristics Reasonable and excellent quality, so won the favor of users.
Uhmw polyethylene sheet has high abrasion resistance, and can be used to make linings of hoppers, silos and chutes for coal silos, cement, lime, mineral powder, salt, and grainy powder materials. Because it has excellent abrasion resistance, self-lubricity, and non-stickiness, the powdery material does not stick to storage and transportation equipment, ensuring stable transportation.
The ultra-high molecular weight polyethylene sheet has a longer service life than steel and does not adhere to high molecular coal bunker linings. Its wear resistance is 3-7 times that of carbon steel and stainless steel. Materials, high impact strength, good comprehensive mechanical properties, resistance to acid, alkali, salt corrosion, no aging, low temperature resistance, health and harmless, light weight, the proportion is 1/8 of steel. Therefore, it is used as the lining material for bulk material storage and transportation equipment, such as storage silos, flow tanks, etc. UHMWPE is a thermal engineering plastic, which combines the superior properties of all plastics. Widely used in electric power, steel plants, coal mines and other industries.
High wear-resistant ultra-high molecular weight polyethylene board is suitable for installation and application under various environmental conditions. It can be designed as an assembly connection structure and can be customized according to user requirements for easy installation and maintenance. The company insists on taking quality as the life, taking the user’s market as the guide, adopting advanced technology to improve product competitiveness, and optimizing after-sales service to solve the worries for customers. For example, the application of hoppers, chutes, and supply hoppers in the metallurgical industry, such as the installation of hoppers and chutes in coal mines with very difficult operating conditions, can solve the problem of sticking and blocking materials during transportation, and achieve safe and normal production.
How should we distinguish the performance of pure uhmw polyethylene sheet? Let’s explain its identification method.
1. Temperature measurement: Pure ultra high molecular weight polyethylene products will not melt or deform at 200 ° C. If it is not a pure ultra-high molecular weight polyethylene material, it will be deformed at 200 degrees Celsius.
- Weighing rule: The specific gravity of products made of pure ultra-high molecular weight polyethylene is between 0.93-0.95g / cm³, the density is small, and it can float on the water. If it is not pure polyethylene, it will sink to the bottom.
- Edge test method: Pure UHMW polyethylene flanging end surface is round, uniform and smooth. If it is not pure polyethylene material, the flanging end surface has cracks, and slag will appear when heating.
- Visual method: The surface of real ultra-high molecular weight polyethylene is flat, uniform, smooth, and the density of the cut surface is very uniform. If it is not pure polyethylene, the color and luster are dark and uneven.
