Shifter Air Slide Cloth Bleach Dyeing Finishing Polyurethane Material Wear Resistance

Exclusive export cotton sifter pads Air Slide Cloth

Cleaning block and pushing block are produced with polyurethane material because of their good toughness and wear resistance required by working conditions. Polyurethane can be divided into polyester type and polyether type according to its molecular structure. Polyether type has good hydrolysis stability, high resilience and low temperature flexibility, and its strength is high. It is suitable for use in high square sieves with high humidity, continuous high strength and high resilience. Polyester type has good tensile properties, flexibility and wear resistance, but its fatal weakness is vulnerable to the invasion of water molecules. Crack. Polyester polyurethane is not suitable because of the high ambient humidity in the high square flat screen under the two-skin grinding, especially under the centrifugal grinding. Because of the large price difference between the two, most of the production enterprises in the industry consider the price, so polyester polyurethane is used to produce cleaning block and pushing block. Therefore, there must be the problem of aging and fracture of polyester polyurethane products after using under the condition of high humidity. Our company relay to recommend to the industry the use of load FDA standard polyether polyurethane cleaning block and push block.
