摘要

研究了涂料的组成——耐火粉骨料、粘结剂、悬浮剂对离心铸造涂料的发气量、悬浮性等的影响

确定了涂料的合适配方。试验结果表明

在涂料发气量≤7.5mL/g时

离心铸铁管不会出现针孔、气孔、凹陷等缺陷。

Abstract

Effects of the components of coating

such as refractory powder filler

adhesive and suspension-agent on the amount of gas evolution from the coating and suspension-ability of coating have been investigated. The proper proportion of coating composition was presented. The results show that absence of the defects in centrifugal casting iron pipe

such as pin-hole

gas holes and misrun

can be observed with amount of gas evolution from the coating less than 7.5 mL/g.
