铸铁轧辊生产中所使用的金属模必须喷刷涂料,以增加金属模使用寿命和提高轧辊表面质量。金属模涂料的种类很多,主要是根据涂料粘结剂和耐高温的填充料来区分的。常用的粘结剂为糖浆、水玻璃,也有用树脂、聚乙烯醇等高分子粘结剂。耐高温的填充料为黑铅粉、喷雾碳黑、焦碳粉、高铝粉等。糖浆涂料成份为:黑铅粉33％,喷雾碳黑50％,糖浆17％。将这些材料配合后,放在旋 Molds used in the production of cast iron rolls must be sprayed with paint to increase the service life of the mold and to improve the surface quality of the rolls. Many types of mold coating, mainly based on paint binders and high temperature filler to distinguish. Common binders for syrup, water glass, but also useful resin, polyvinyl alcohol and other polymer binder. High temperature filler for the black lead powder, spray carbon black, coke powder, high-aluminum powder. Ingredients for the syrup coating are: black lead powder 33%, spray carbon black 50%, syrup 17%. After fitting these materials, place on the spin
