BS EN ISO 4612:2018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。交叉引用:

BS EN ISO 4612:2018 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.Cross References:ISO 291All current amendments available at time of purchase are included with the purchase of this document.
