調(diào)配比例是石膏粉的使用技巧比較重要的環(huán)節(jié)：模具石膏粉調(diào)配比例為 28(水)：100（石膏粉）行翘，這個(gè)混合比是混合比隘擎，制作出的石膏產(chǎn)品可以達(dá)到瓷磚的效果跳窖，表面用指甲根本劃不出痕跡兔跌。但按照這種混合比調(diào)配石膏粉座享，對(duì)新手而言難度太大运悲，混合比例的精確掌握龄减、選用的攪拌容器、攪拌手法班眯、凝固時(shí)間都不好控制欺殿。故一般建議采用35：100的比例調(diào)配石膏粉，也可以達(dá)到很不錯(cuò)的效果鳖敷。

　　The mixing proportion is an important part of the use skill of gypsum powder: the mixing proportion of mold gypsum powder is 28 (water): 100 (gypsum powder), which is the highest mixing ratio. The gypsum product can achieve the effect of ceramic tile, and the surface can not be scratched with nails. But according to this mixing ratio, it is too difficult for the novice to prepare gypsum powder. The accurate control of mixing ratio, the selected mixing container, mixing technique and setting time are not easy to control. Therefore, it is generally recommended to use the proportion of 35:100 to mix gypsum powder, which can also achieve very good results.

　　調(diào)配石膏粉次序：先加水后加石膏粉脖苏，切記這點(diǎn)很重要，先粉后水石膏粉很難攪拌到非常均勻定踱，石膏的硬度與攪拌的均勻程度是成正比的盼掘，攪拌越均勻，牢度越高耸颁。

　　Mixing order of gypsum powder: add water first and then gypsum powder. It is very important to remember this point. It is difficult to mix gypsum powder first and then gypsum powder. The hardness of gypsum is directly proportional to the uniformity of mixing. The more uniform the mixing, the higher the fastness.

　　凝固時(shí)間的掌握：凝固時(shí)間主要與加水量有關(guān)系（添加劑另外說(shuō)明）彰巫，次之與攪拌時(shí)間、澆鑄容器舞绝、溫度童丢、濕度有關(guān)系。首先水吆踏、石膏粉混合比择车，水越多石膏凝結(jié)時(shí)間越長(zhǎng)，石膏密度越低轩丁、牢度越低阀严，水越少凝結(jié)時(shí)間越短、密度越大仙商、牢度越高砚凳，具體需根據(jù)使用需求來(lái)控制。然后談下攪拌時(shí)間钞钙，一般而言攪拌到石膏粉非常均勻即可澆鑄鳄橘，一般控制在5分鐘之內(nèi)，攪拌時(shí)間越長(zhǎng)芒炼，石膏粉凝固時(shí)間越快瘫怜。

　　Control of setting time: the setting time is mainly related to the amount of water added (the additives are also explained), and then to the mixing time, casting container, temperature and humidity. First of all, the mixing ratio of water and gypsum powder, the more water, the longer the setting time of gypsum, the lower the density and the lower the fastness of gypsum, the shorter the setting time of less water, the higher the density and the higher the fastness, which should be controlled according to the use demand. Then talk about the mixing time. Generally speaking, the gypsum powder can be cast when it is stirred to be very uniform. Generally, it is controlled within 5 minutes. The longer the mixing time is, the faster the setting time of gypsum powder is.
