摘要
根据国内石膏型混合料的现状,选用不同材料、不同比例的石膏型混合料,采用正交实验法测定其工艺性能。混合料中的填料为:石英砂和铝矾土。石膏型混合料主要的工艺性能有:线膨胀率、抗拉强度、流动性和胶凝时间。影响混合料工艺性能的主要因素是:填料种类、加水量和填料加入量。试验确定并证实了一种性能优异的石膏型混合料的最佳配比:填料是石英砂,加水量是35%,填料加入量是60%。
According to the current situation of study about the technological properties of plaster mould mix in our country,interactive test way is the method of testing technological properties of the plaster mould mixture with different materials and various proportions.Fillers added to the mixture are quartz sand and alumina.The main technological properties are linear expansivity,tensile strength,flowability and solidification time.The kinds of filler,addition amount of water and addition amount of fillers are m...
