The main problems caused by stomatal cable There are two reasons for this problem retardant PVC manufacturer in Weifang, one raw material moisture retardant PVC manufacturers high, there may be excessive moisture in the raw materials are PVC resins, plasticizers, fillers and stabilizer, the addition of a greater amount, PVC resin and filler should be the focus of inspection. This situation Weifang retardant PVC, usually in the kneading process and vacuum extruder will be at the show. Second, because the formula system stability is poor or material temperature stays too long, resulting in material decomposition pores appear. This problem is serious, usually accompanied by a change in color. Mixing process material to this great impact. In particular, the order of addition of various additives in the mixing process and the timing (temperature or in front of the degree of mixing of materials), had a significant effect on the mixing process plasticizer absorption and dispersion of precipitates cable problem, which is all easy to ignore the problem. To try to ensure that when mixing with PVC resin plasticizer sufficient mixing time and a certain degree of mixing temperature (about 90 ℃).
