　　濟(jì)南石膏粉的混合方法

　　ThemixingmethodofJinangypsumpowder

　　1、高硬度石膏粉的混合方法:僅石膏粉與水，石膏粉與水的比例為100:28，將比例調(diào)和。

　　2、先加入水，然后再加入石膏粉，記住這一點(diǎn)很重要，假如先加入水再加入石膏粉，兩者很難混合均勻，石膏的硬度和攪拌均勻度成比例，攪拌越均勻，牢度越高。

　　3.控制固化時(shí)間。凝固時(shí)間主要與加水量有關(guān)，其次是攪拌時(shí)間、鑄造容器、溫度和濕度。水、石膏粉配合比首先，水石膏凝結(jié)時(shí)間越長(zhǎng)，石膏密度越低，牢度越低，水越少凝結(jié)時(shí)間越短，密度越大，牢度越高，具體需要根據(jù)使用需要控制。

　　4,白色的石膏和制備塑料添加劑:乳白膠可以提高石膏的牢度,乳白膠添加會(huì)使石膏凝結(jié)時(shí)間延長(zhǎng),乳白膠凝固,時(shí)間越長(zhǎng)越添加一個(gè)乳白膠固化后(更多)石膏表面細(xì)膩的感覺(jué),顏色不容易吸收的石膏、油漆才會(huì)停止在石膏表面。在制作粗糙表面時(shí)，需要石膏自然吸收色素，要注重，是否加乳白色膠水是會(huì)影響更終效果的。
