The reality is that so the corrosion resistance of polyurethane casters leverage drops

The reality is that so the corrosion resistance of polyurethane casters leverage, increase the friction coefficient of polyurethane casters, is conducive to the grip and the improvement of fiber yarn evenness evenness. But the friction coefficient is big, is easy to produce static electricity, the pu castor around the flowers, to make production. To all kinds of the surface of pu castor, for all kinds of chemical coating contains a variety of strong polarity of resin and aliphatic, eyes in eyes with butyl rubber crosslinking curing into a film. In spinning is held to ensure the stability of the drafting, just have good resilience, and weak sex requirement tire smaller permanent opening of shape, under the same pressure of large diameter roller has good elasticity, and Laura arc contact area is large, the friction boundary expansion, the floating area, strong control of floating fibers, is advantageous to the variable speed point jaw forward focus on comparison of vibration absorption, Laura groove can be reduced or dust miscellaneous cause fluctuations, make the tire lateral uniformity improve grip strength, is helpful to control the movement of the article to the edge of fiber. Working in special high temperature or low temperature, or working environment temperature difference is very big, should choose metal wheels or special high temperature resistant wheels; Where the requirements to prevent the accumulation of electrostatic generation, had better use special anti-static wheel, also can choose metal wheel ( If the ground does not require protection, ; Work environment there are many corrosive medium, should choose to have good corrosion resistance of the wheel accordingly. Soft foam plastic is mainly used for furniture and transport all kinds of cushion materials, insulation materials, etc. ; Hard foam is mainly used in household appliances waterproof spray foam insulation layer, the house wall, pipe insulation materials, building plank, refrigerator and cold storage insulation material, etc. ; Half hard foam used in automobile dashboard, the steering wheel, etc. Market has polyurethane foam composite materials that are used for various specifications ( Two-component premix) Mainly used for ( Cold cure) High resilience foam, half hard foam plastic, casting and spraying hard foam plastic, etc. The reality is that so the corrosion resistance of polyurethane casters leverage, more news and information about pu castor please click: hynews / 279. html
