铸铁EPC法水基涂料的研制

Development of Water-based Coating for EPC Cast Iron

选用石英粉为耐火骨料,PVA、酸式磷酸盐为复合粘合剂,PNa与CMC为复合悬浮剂,通过正交试验确定了铸铁件消失模水基涂料的最佳配比。性能测试和生产验证表明,所研制的涂料能很好适应生产要求。

Using quartz powder as refractory aggregate,PVA and phosphate as composite binder,PNa and CMC as composite suspension agent,the best proportion of water-based coating for EPC iron castings was determined by orthogonal test.The performance testing and production test show that developed coating can meet the requirements of production.
