Polyurethane elastomer is a new type of polymer synthetic material between rubber and plastic. It has both high strength of plastic and high elasticity of rubber. Its characteristics are as follows:
1. The hardness range is wide. It still has the elongation and resilience of rubber at high hardness. The hardness range of the polyurethane elastomer is Shaw A10-D80.
2. The intensity is high. In the rubber hardness tensile strength and their bearing capacity than the general rubber is much higher. At high hardness, the impact strength and the bending strength are much higher than that of the plastic.
3, wear-resistant. The wear performance is very outstanding, in general 0.01-0.10 (CM fand /1.61km range) is about 3-5 times of rubber.
4. Oil resistance. Polyurethane elastomer is a kind of strong polar macromolecule compound. It has little affinity with non polar mineral oil, and is almost not corroded in fuel oil and mechanical oil.
5. The performance of oxygen resistance and ozone is good.
6, excellent vibration absorption performance, can be used to reduce vibration and buffer. In mould manufacturing, rubber and spring are replaced.
7. It has good low temperature performance.
8. Radiation resistance. The performance of the polyurethane with high energy radiation is very good, and it still has satisfactory performance under the 10-10 - Ge radiation dose.
9. It has good mechanical properties. (car, milling, grinding, Zuan Junke)
The vertical and horizontal bars of the screen are made of high wear-resistant polyurethane, and the steel wire is contained in the strip. The service life is 3-10 times higher than that of the traditional metal screen. The unique structure, the suitable elastic plastic force, can reduce the blocking, at the same time the two harmonic high-frequency vibration of the screen, and can reduce the plugging. The practical opening rate is high and the sieving efficiency is high. There are elastic tensioning hooks on both sides of the screen, with light weight, good flexibility, easy transportation and storage, easy installation and disassembly. The screen can effectively absorb the impact, reduce the noise and improve the working environment.
Metallurgy, such as metallurgy, iron ore, limestone, fluorite, cooling blast furnace slag, coke and other raw materials, color, yellow, coal, chemical industry, building materials and Hydropower Engineering, abrasive waste treatment, quarry and other industries, such as ore washing, screening, grading and other industries. A new type of structural model sieve plate with various size and sieve size, especially for the occasion of strong impact, high hardness and high wear resistance. Wear-resistant sieve plates are used in fine-grained sieving, classification of raw coal, gold, building materials, and screening of sand and stone for hydropower and nuclear power projects in iron ore.
Frame type sieve plate, strip hole sieve plate, tight sieve plate slit sieve plate. Square hole screen mesh, large hole screen mesh, small hole screen mesh, polyurethane rope weave screen mesh, slit screen.
