该文件指定了两种方法A和B,用适当的PVC树脂、增塑剂和其它成分使用行星混合过程来制备糊剂(也称为增塑溶胶)。方法A和方法B均可用于制备任何成分的糊料。方法A(单速)特别适用于在糊料制备过程中容易积聚的树脂,而B(2速)可能是重复工作的首选,例如在树脂制造过程中的过程控制,因为其较短的混合时间。此类糊料可用于各种试验目的,包括测定树脂名称和规格的流变性能。
This document specifies two methods, A and B, for the preparation of pastes (also known as plastisols) from appropriate PVC resins, plasticizers and other ingredients using a planetary mixing process. Both method A and method B can be used to prepare pastes of any composition. Method A (single-speed) is particularly applicable to resins prone to heat build-up during paste preparation, while method B (two-speed) might be preferred for repetitive work, e.g. for process control during resin manufacture, because of its shorter mixing time. Such pastes can be used for a variety of test purposes, including the determination of rheological properties for resin designation and specification.
