Polyurethane sieve plate is a kind of mesh products produced with polyurethane as raw material. The hole shape of the sieve plate is divided into slits, rectangles, circles, squares, etc. It has good wear resistance, oil resistance, hydrolysis resistance, bacteria resistance, and Aging performance, widely used in coal washing plants, coking plants, mines, power plants, dredging companies, metallurgy, petroleum, petrochemical and other industries.
Polyurethane sieve plate for mining: make full use of the wear resistance, high strength, high elongation and high elasticity of polyurethane elastomer**, good shock absorption performance, oil resistance, low temperature resistance, heat aging resistance, radiation resistance, electrical insulation and other properties , Coupled with its reasonable screen structure and installation structure design, so that the mine polyurethane screen has the following characteristics:
1. Good wear resistance: long service life, its wear resistance is 3-5 times that of steel sieve plates and more than 5 times that of ordinary rubber sieve plates.
2. Reduce maintenance rate: The polyurethane screen is not easy to be damaged and has a long service life, so it can greatly reduce the amount of maintenance and the loss of maintenance.
3. Low total cost: Although the one-time investment of polyurethane sieve plate of the same specification (area) is higher than that of stainless steel sieve plate (about twice), the service life of polyurethane sieve plate is 3-5 times that of stainless steel sieve plate, and maintenance and replacement are required. The frequency is small, so economical application is the best choice.
4. Good moisture resistance: it can work under the condition of water as the cut-off, and in the case of water, oil and other media, the friction coefficient between polyurethane and the material is reduced, which is more conducive to screen penetration, improves screen resolution, and can avoid wet particles At the same time, due to the reduced friction coefficient, the wear is reduced and the service life is increased.
5. Corrosion resistance: non-flammable, non-toxic and tasteless.
6. Anti-clogging: Due to the reasonable design of the sieve holes and the unique manufacturing process of the sieve plate, the particles of the limit size will not block the sieve holes.
7. Good vibration absorption performance: strong noise reduction ability, can reduce noise, and can prevent the screen from breaking during the vibration process.
8. The polyurethane screen has a self-cleaning effect, so the screening efficiency is high.
9. Energy saving and consumption reduction, the specific gravity of polyurethane is small, which is much lighter than the same size screen, thus reducing the load of the screen machine, saving power consumption, and extending the life of the screen machine.
