摘要
由白云岩加工而成的钙镁粉,用作橡胶填料的实际生产,并不多见。本文首次总结了钙镁粉在橡胶填料中的应用可行性。经多项物性测试证实,作为一种新的填充剂和着色剂,钙镁粉的技术指标达到或超过了轻钙粉的水平,在某些橡胶制品中,可以部分或全部代替轻钙粉和立德粉。
The calcium-magnesium powder produced from dolomite is not commonly used as a filler in rubber production.The paper summarizes its applicability for the first time as a rubber filler.Tests on the physical properties of the calcium-magnesium powder indicate that,as a new filler and colouring agent,it is equivalent or superior to the light calcium powder in terms of technical indices,and can be used to replace partly or entirely the light calcium powder and lithopone in some rubber products.
