　　济南石膏粉的混合方法

　　ThemixingmethodofJinangypsumpowder

　　1、高硬度石膏粉的混合方法:仅石膏粉与水，石膏粉与水的比例为100:28，将比例调和。

　　2、先加入水，然后再加入石膏粉，记住这一点很重要，假如先加入水再加入石膏粉，两者很难混合均匀，石膏的硬度和搅拌均匀度成比例，搅拌越均匀，牢度越高。

　　3.控制固化时间。凝固时间主要与加水量有关，其次是搅拌时间、铸造容器、温度和湿度。水、石膏粉配合比首先，水石膏凝结时间越长，石膏密度越低，牢度越低，水越少凝结时间越短，密度越大，牢度越高，具体需要根据使用需要控制。

　　4,白色的石膏和制备塑料添加剂:乳白胶可以提高石膏的牢度,乳白胶添加会使石膏凝结时间延长,乳白胶凝固,时间越长越添加一个乳白胶固化后(更多)石膏表面细腻的感觉,颜色不容易吸收的石膏、油漆才会停止在石膏表面。在制作粗糙表面时，需要石膏自然吸收色素，要注重，是否加乳白色胶水是会影响更终效果的。
