聚氨酯筛网、筛板广泛使用于冶金、矿山、、建材、水利、筑路,煤矿，金属和非金属矿山选矿的筛分机上。筛网中用钢丝，钢板作为增强骨架，再加上聚氨酯本身具有非常高的弹性模量，高强度吸收冲击力、高耐磨，因而具有很高的拉伸强度，其承载能力是橡胶筛网的2.5倍以上。其使用寿命与普通金属筛网相比提高8-10倍，是不锈钢筛面的3倍，是天然橡胶的3.9倍，是目前世界上耐磨性能最佳的筛面材料。聚氨酯筛网的生产材料属高分子有机弹性体、具有极好的抗磨损性、耐屈挠性、承载能力大。筛分效率高，筛面其内自洁性能，不堵孔、筛分效率高。根据实际测定，同样的筛机使用聚氨酯筛网比金属筛网可降低噪音5-20分贝，并大大减少粉尘飞扬。虽然聚氨酯橡胶筛面的价格较金属筛网高，但如果综合考虑筛分效率、维修费用、使用寿命等因素，就会发现聚氨酯筛面的整体效益要大大优于普通金属筛面。据调查，每使用一吨聚氨酯橡胶筛板即可节约钢材45吨。节约维修费用4万余元。因此聚氨酯筛面替代钢制筛面将是今后绝大多数企业的必然选择！
Polyurethane sieve and mesh performance characteristics
Polyurethane sieve and screening widely used in metallurgy, mining, building materials, water conservancy, road construction, coal, metal and nonmetal mines beneficiation screening machines.
Polyurethane sieve produce with wire mesh, reinforcing steel as skeleton, coupled with kind of polyurethane property has a very high elastic modulus, high strength to absorb impact, high abrasion resistance, which has high tensile strength, its carrying capacity is rubber mesh 2.5 times more. Its life improved as compared with ordinary metal mesh 8-10 times, three times the screen surface of stainless steel, and 3.9 times of natural rubber, there is the best material in the world on the screen surface wear. Screen production material is a polyurethane polymer organic elastomer, has excellent abrasion resistance, flex resistance, carrying capacity. High efficiency, self-cleaning properties within the screen surface, no clogging, high screening efficiency. The actual measured according to the same uses polyurethane mesh sieve over metal mesh to reduce noise 5-20 dB, and greatly reduce the dust. Although polyurethane mesh price is higher than the metal screen, but if considering the screening efficiency, maintenance costs, life and other factors, will find the overall effectiveness of the polyurethane screen surface to be much better than ordinary metal sieve. According to the survey, with each one ton of polyurethane sieve can save 45 tons of steel. Save maintenance costs $7000. Therefore polyurethane screen surface replacement steel screen surface will be the inevitable choice of the vast majority of enterprises in the future!
