CPVC ning yuqori erigan viskozitesi tufayli, ayniqsa qarshi kalıplamada, u eriydigan sindirishga moyil bo'ladi, shuning uchun faqat an'anaviy kerosin mumi, stearik kislota va metall sovunni moylash tizimlaridan foydalanish mos emas. CPVC ni ekstruziya bilan qayta ishlashda, CPVC issiq post{0}}qayta ishlash uskunasining (ayniqsa, matritsa) metall yuzasiga yopishib qolish tendentsiyasiga ega bo'lganligi sababli, bu yopishishni bartaraf etish uchun tashqi moylash vositasi qo'shilishi kerak. formulaga. Tashqi moylash materiallari va CPVC qatronlari aralashmasligi kerak.
In the CPVC molding process (especially the injection process), under the action of pressure, the mutual friction between the CPVC resins generates frictional heat. The generation of frictional heat is unfavorable to the molding process and must be controlled. Internal lubricants reduce the friction between resins during CPVC processing. The internal lubricant and CPVC resin should be compatible. It should be noted that the balance of internal and external lubrication in the formulation is key. Excessive internal lubrication will seriously affect "plasticization" and deteriorate the quality of products; excessive external lubrication will cause lubricant precipitation, and even lead to screw slippage and other phenomena that seriously affect normal production. The OP wax (montan ester wax) in the saponified wax is an ideal internal and external compound lubricant.
