Advantages of Polyurethane Sieve

1, long life, carrying capacity. As the use of polyurethane flexible wire mesh frame for the skeleton material, coupled with the polyurethane itself has a very high elastic modulus, high strength absorption impact, high wear resistance, which has a high tensile strength, its carrying capacity is rubber mesh More than 2.5 times. Its life and ordinary metal screen compared to improve 8-10 times, is the stainless steel screen surface 3 times, 3.9 times the natural rubber, is the world’s best wear resistance of the screen surface material. Polyurethane screen material is a high molecular organic elastomer, with excellent wear resistance, flex resistance, load capacity. Polyurethane screen production of raw materials through a special treatment to ensure that the long-term alternating load will never delamination.
2, high screening efficiency. Sieve surface within the self-cleaning performance, no blocking, high screening efficiency. Because of the strong water permeability of the polyurethane and the large angle of the sieve (140 °), it can effectively prevent the adhesion of the wet fine particles, so it is suitable for the classification of the wet fine material. I plant polyurethane mesh using imported raw materials, the elastic body and its good Chi Zhang performance, in the dynamic case to effectively prevent the phenomenon of plugging.
3, for a wide range of professional applicability of more applicable to any type of vibrating screen machine and the amount of machine production. Polyurethane screen professional used in hydropower stations, building materials and other metal dressing. 0.1mm-170mm range of various materials screening, regardless of dry sieve, wet sieve does not affect the screening efficiency. Dehydration and delamination in the range of 0.5m-3mm, more fully shows the superiority of polyurethane screen surface. Products resistant to water, corrosion resistance, anti-aging, easy to replace and maintain. Polyurethane density is small (1.32kg / m 3), lighter than the metal screen surface, can reduce the production unit consumption, it can adapt to the development of large-scale screening machine requirements.
4, high precision screening. Polyurethane screen production process using mold casting process, the aperture is accurate, high quality screening, sieve material under the screen size can be well in line with the requirements of users. Easy installation, easy replacement and replacement, the product is suitable for any type of screen, light weight, for the field installation or replacement maintenance, greatly reducing the workload.
5, low noise, in line with national standards of environmental noise standards. According to the actual determination, the same sieve machine using polyurethane mesh than the metal mesh can reduce the noise 5-20 dB, and greatly reduce the dust flying, so that the production site has a quiet clean working environment.
6, significant economic benefits. Although the price of polyurethane rubber screen surface is higher than that of metal mesh, if the factors such as screening efficiency, maintenance cost and service life are taken into account, it is found that the overall efficiency of polyurethane screen surface is much better than that of ordinary metal screen. According to the survey, each use of a ton of polyurethane rubber sieve plate can save 45 tons of steel. Saving maintenance costs 4 million yuan. So the polyurethane screen surface instead of steel screen surface will be the vast majority of enterprises in the future the inevitable choice.
