标准摘要
[中文适用范围]： 本文件规定了使用行星混合过程从适当 PVC 树脂、增塑剂和其他成分制备糊（也称为 plastisols）的两种方法 A 和 B。 [外文原描述]： 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.
