摘要

针对球墨铸铁管件的消失模铸造工艺

以铝矾土、石英粉、云母为耐火骨料

膨润土和羧甲基纤维素钠（CMC）为复合悬浮剂

聚乙烯醇（PVA）为粘结剂

进行了耐火涂料的研制。通过涂料的制备和性能检测

并结合生产实际证明

所研制的涂料性能良好

可满足生产要求。

Abstract

The coating which was made of alumina

quartz powder and mica as refractory materials

bentonite of natrium and CMC as compound deflocculant

polyvinyl alcohol（PVA） as agglomerant was developed for lost foam casting ductile iron pipe.The performances of the coating prepared were measured.The results show that the coating developed exhibits good performance

meeting production requirements.
