Title:PE Coating Process For Chain ࡡProductNum:JS1001 Spec: Unit: Hits:111 Memo:PE coating process for chain Date:2007-10-13

      The chain has flexibility and also has a great difficult in processing.The raw material is the PVC liquid coating which is soft and has strong adhesion.

      First, carrying on the phosphorization and cleaning up the chain before coating, spreading the iron hardening agent of kody's on the surface.

     Second, The chain adopts the way of even hanging and then be put into the preheating tunnel, the tunnel temperature is in 320℃～390℃ scope, the equipment will automatically stop heating when the temperature has achieved the standard, maintaining this temperature to guarantee each raid of product coating can be able in the certain thickness.

    Third,the plasticizing temperature to be controled in 240℃～260℃, according to the granularity of chain and the processing quantity of one time, the plasticizing time to be controled in 40～80 seconds. 

    Fourth, please do not pack the chain immediately after coating, using the impervious membrane to wrap and warehousing it after it turns to the normal temperature.
