水玻璃工艺生产是一个多环节、多因素的生产过程。根据多年经验 ,要生产出优质的铸件就必须注意生产过程的多个细小的环节 :如蜡模必须经过洗涤 ,消除蜡屑和油污 ;模料要定期检测酸值 ,以补加硬脂酸 ;涂料的表面活性剂要控制适当 ;在使用氯化镁硬化液时 ,要提高酸度 ,针对其特点要勤添、少量。只有全面地、细致地控制各工艺环节的操作 ,才能生产出优质铸件 Water glass production process is a multi-link, multi-factor production process. According to years of experience, to produce high-quality castings must pay attention to many small steps in the production process: such as wax mold must be washed to eliminate wax and oil; mold material to be detected regularly to add stearic acid; Paint the surfactant to control properly; in the use of magnesium chloride hardening solution, to increase the acidity, according to its characteristics should be diligent, a small amount. Only a comprehensive and meticulous control of the process of operation, in order to produce high-quality castings
