一、概述型、芯砂的粘模性是指造型混合料与模具或芯盒、混砂和贮运设备的表面粘附能力。近年来水溶性高分子粘结剂日益在铸造中推广应用,由於水与模具材料的湿润能力比较强,因此用水溶性粘结剂配成的混合料往往会出现粘模性高的问题。因此,测定粘模性,研究其产生原因和影响因素以及调节和改善等问题具有一定意义。型、芯砂粘模性的测定国内外尚未出现一个标准方法。1953年美国铸造师协会曾成立了一个专门研究型、芯砂粘模性的学组、
First, an overview of the core sand sticky mold refers to the molding mixture or the core box, sand and storage equipment surface adhesion. In recent years, water-soluble polymer binder is increasingly used in casting. Since the wetting ability of water and mold material is relatively strong, the mixture with water-soluble binder tends to have a problem of high adhesiveness. Therefore, the determination of sticky mold, to study its causes and influencing factors as well as regulation and improvement of a certain significance. Type, the determination of the core sand mold has not yet appeared at home and abroad a standard method. 1953 American Foundry Association has set up a special research, core sand sticky group,
