本文阐述了铸铁型芯用涂料的作用,介绍了不同涂料类型即:以水作溶剂的水基涂料,以酒精或汽油作溶剂的快干燃烧涂料和以某种气体如氟利昂或易挥发的液体如三氯乙烯和其它含氯溶剂作稀释剂的自干涂料。按用途分又可分为:用来堵塞砂粒间隙的普通涂料以及用作增强型芯表面机械性能的浸渗涂料(其渗透深度可达几毫米)。对配制涂料的成分如耐火材料、粘结剂、溶剂及流变剂和各种必需的添加荊进行了探讨,论述了涂料的配制、控制及使用方法,指出了因
This article describes the role of cast iron core coatings and describes the different types of coatings: water-borne coatings based on water, fast-drying combustion coatings using alcohol or gasoline as a solvent, and coatings with a gas such as Freon or a volatile liquid Such as trichlorethylene and other chlorinated solvents as a thinner of the dry coating. According to the use of points can be divided into: to block the gap between the common sand paint and used to enhance the mechanical properties of the core surface of the impregnated coating (penetration depth of up to several millimeters). The ingredients of the coating such as refractories, adhesives, solvents and rheological agents and various necessary additives were discussed. The preparation, controlling and using methods of coatings were discussed.
