标准范围

本文件规定了两种方法A和B，用于使用行星式混合工艺，从适当的PVC树脂、增塑剂和其他成分制备糊料（也称为塑性溶胶）。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）特别适用于在制备膏体过程中容易受热的树脂，而方法B（双速）可能更适合于重复性工作，例如树脂制造过程中的过程控制，因为其混合时间较短。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.
