Why more and more people choose to use pu castor

Why more and more people choose to use pu castor? Wheel can not turn if it is match the pu castor castor inserted rod, to ensure that equipment installation hole is not bent, and inserted link closely linked. Using locknut or check washer to install castor confirm whether expansion rubber sets of installation location tighten in place to add lubricant to add lubricant to pu castor castor or wheels on a regular basis. 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. Penetrating agent makes the coating can penetrate into the rubber surface, forming flexible good molecular chains, make coating toughness, impact resistance, resistance to bending, and good abrasion resistance, and can withstand oil, acid and alkali resistance and ozone resistance and other properties. 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. Stalemate with the core surface should be clean decontamination & rsquo; Alkaline degreasing & rsquo; Acidification of rust removal, etc. After dealing with the surface of iron core, in the rubber surface must be heated before coating. Place the after coating and adhesive glue iron core in the cavity, until the casting by heating and fully stir well in advance of mixed liquid in the process must control the anti-fouling, avoid the secondary pollution and dust impurities, etc. Pu castor hardness broad index, can meet the requirements of different type printing machine on the caster and hardness. Pu castor with colloid has enough surface viscosity, can guarantee the castor good transfer in the process of printing ink and inking performance, its good hydrophilic performance ensures high quality printing ink.
