Polyurethane mesh has good abrasion resistance. Polyurethane itself has high elastic modulus, high strength, impact resistance, high wear resistance and high tensile strength, so its bearing capacity is high, which is more than 2.5 times that of a rubber screen plate. Its service life is 8-10 times that of ordinary metal sieves, 3 times that of stainless steel sieves, and 3.9 times that of natural rubber.
Polyurethane screen is a kind of polymer elastic screen, which has excellent wear resistance, oil resistance, hydrolysis resistance, bacteria resistance and aging resistance. The screen can not only greatly reduce the weight of the equipment, reduce the cost of the equipment, prolong the service life, but also reduce the noise. It should be widely used in the mining, metallurgy, coal, coke, coal washing, petroleum, chemical,
and other industries.
As one of the main accessories of the screening and sorting equipment, the screen is also one of the wearing parts. High-quality screens are very wear-resistant, corrosion-resistant and have a long service life. Users often replace new screens and can reduce production costs. The inferior screen mesh has a short service life, and the user needs to replace the screen mesh frequently, thereby increasing the production cost. Therefore, when you choose a polyurethane screen, you must choose a high-quality screen produced by a regular manufacturer. Here, I will share with you how to choose a high-quality screen.
1. Observe the appearance. A good polyurethane screen has a flat surface, uniform mesh size, pure color, neat edges, and uniform edges of the edge-wrapped screen.
2. Hand touch, foot pedal. The screen surface of the screen should be smooth and not rough; use the foot to see the slump of the screen surface, a good polyurethane screen should have strong elasticity and resistance, and the screen should be moderately rigid and flexible.
3. Look at the opening rate. The more the number of sieve holes, the higher the opening rate, the higher the sieving efficiency and the output.
4. Pay attention to the connection situation. That is to say, the connection between the screen and the screen during installation, the poor connection of the connection will directly affect the screening efficiency.
It is very important to choose a high-quality polyurethane screen, because it is not only related to the effect of equipment screening materials, but also has a great impact on the economic benefits of users. I hope the above tips will help you!
