高強度陶瓷石膏粉具有粘度低、強度高、膨脹率低等優良性能。用戶可以用這種石膏粉制作高強度機壓模或壓漿模。石膏粉也可在模具車間與普通石膏粉按不同比例混合使用,提高普通石膏粉的強度,滿足各種成型工藝的經濟要求。
High strength ceramic gypsum powder has many excellent properties, such as low viscosity, high strength and low expansion rate. Users can use this kind of gypsum powder to make high strength press die or grouting die. Gypsum powder can also be mixed with ordinary gypsum powder in different proportions in the mould workshop to improve the strength of ordinary gypsum powder and meet the economic requirements of various forming processes.
巴黎石膏的膏體與水混合后逐漸凝固成硬塊,過程類似于CaSO4??H2O CaSO4 ? ?2H2O的反應放出大量的熱量,生成了CaSO4??2H2O相互結合形成多孔固體。影響熟石膏凝結速度的因素包括熟石膏粉的質量、熟石膏粉與水混合比例不當、攪拌時間和速度、水溫等。巴黎石膏的操作注意事項:1。石膏粉與水混合后,若水粉比例不合適,再取適量調和。2. 攪拌速度不宜過快,以免人為地帶入氣泡,形成過多的結晶中心,導致石膏膨脹,強度降低。3.灌注模型由一側逐漸向另一側移動,通過搖動灌注,消除氣泡,填充所有細小部位。4. 石膏在凝固過程中發生體積膨脹。
After mixing with water, the gypsum of Paris gypsum gradually solidifies into hard blocks. The process is similar to the reaction of CaSO4?? H2O?? CaSO4?? 2H2O, which releases a lot of heat and produces CaSO4?? 2H2O which combines with each other to form porous solids. The factors affecting the setting speed of plaster include the quality of plaster powder, the improper mixing ratio of plaster powder to water, mixing time and speed, water temperature, etc. Notes for operation of Paris gypsum: 1. After mixing gypsum powder with water, if the proportion of water powder is not appropriate, then take appropriate amount of mixing. 2. Mixing speed should not be too fast, so as not to artificially bring in bubbles, forming too many crystallization centers, resulting in gypsum expansion and strength reduction. 3. The perfusion model moves gradually from one side to the other. By shaking the perfusion, the bubbles are eliminated and all the small parts are filled. 4. The volume expansion of gypsum occurs during solidification.


石膏的凝結時間一般取決于石膏粉標簽的標號高,一般凝結快。但是減緩石膏凝固速度的方法是使用冷水,當你往水中添加石膏粉時,冷水。你什么都不用做。如果你認為這是不可能的,你可以添加檸檬酸或你可以混合膩子粉與石膏粉,加入108橡膠白乳膠和纖維素在水中,然后混合它
The setting time of gypsum generally depends on the high label of gypsum powder, and the setting time is usually fast. But the way to slow down the solidification rate of gypsum is to use cold water, when you add gypsum powder to the water, cold water. You don't have to do anything. If you think this is impossible, you can add citric acid or you can mix putty powder with gypsum powder, add 108 rubber white latex and cellulose in water, and then mix it.
陶瓷模石膏粉是我國應用的一種重要石膏類型。隨著國民經濟的快速發展,陶瓷衛生潔具市場不斷擴大。陶瓷石膏粉需求量大,質量好。陶瓷模具因其生產工藝、用途和模具制造而異。陶瓷石膏粉具有不同的性能要求。
Ceramic mould gypsum powder is an important type of gypsum used in China. With the rapid development of national economy, the market of ceramic sanitary ware is expanding. Ceramic gypsum powder is in great demand and of good quality. Ceramic moulds differ from one another in terms of production technology, use and moulding. Ceramic gypsum powder has different performance requirements.
