因为精密铸造公司难以对这种有机化学主要参数进行检验,因此,一方面要加强供货方的挑选、评价和确定,另一方面,面层和背层应选择用不一样型号的硅溶胶,入面层挑选S-830硅溶胶,背层挑选S-1430硅溶胶。涂料的配制方式在精密铸造时会直接影响专业精密铸造件的品质,那么我们先了解一下涂料的配制。
涂料配制一般先放硅溶胶,加上润湿剂搅拌,在拌和里加入防火颗粒料,最终添加消泡助剂。为确保涂料品质,面层涂料均为全新料时,拌和时长应超过24h才能进行,如部分是新调料,拌和时长可减少为12h。过渡层及背层涂料拌和时长可低于面层涂料,均为新配涂料时,拌和时长超过10h,部分是新配时,拌和时长可减少一半。配好的涂料如不能使用,应盖上密封性避免水分流失。
