聚氨酯篩網、篩板廣泛使用于冶金、礦山、、建材、水利、筑路,煤礦，金屬和非金屬礦山選礦的篩分機上。篩網中用鋼絲，鋼板作為增強骨架，再加上聚氨酯本身具有非常高的彈性模量，高強度吸收沖擊力、高耐磨，因而具有很高的拉伸強度，其承載能力是橡膠篩網的2.5倍以上。其使用壽命與普通金屬篩網相比提高8-10倍，是不銹鋼篩面的3倍，是天然橡膠的3.9倍，是目前世界上耐磨性能最佳的篩面材料。聚氨酯篩網的生產材料屬高分子有機彈性體、具有極好的抗磨損性、耐屈撓性、承載能力大。篩分效率高，篩面其內自潔性能，不堵孔、篩分效率高。根據實際測定，同樣的篩機使用聚氨酯篩網比金屬篩網可降低噪音5-20分貝，并大大減少粉塵飛揚。雖然聚氨酯橡膠篩面的價格較金屬篩網高，但如果綜合考慮篩分效率、維修費用、使用壽命等因素，就會發現聚氨酯篩面的整體效益要大大優于普通金屬篩面。據調查，每使用一噸聚氨酯橡膠篩板即可節約鋼材45噸。節約維修費用4萬余元。因此聚氨酯篩面替代鋼制篩面將是今后絕大多數企業的必然選擇！
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!
