1. When repairing the wall, we must choose Jinan gypsum powder with good hardness. The ratio of water to gypsum powder is 28:100, so that we can directly mix according to the ratio. When mixing, water must be added first, and then gypsum powder. If it is the opposite, it is difficult to mix the two evenly. The more evenly the gypsum powder and water are mixed, the stronger the gypsum will be.

2、石膏凝固時(shí)間與加水量關(guān)系很大，其次就是攪拌時(shí)間，溫度和濕度等一方面。水加的太多那凝固時(shí)間就越長，那也就會不會牢固，反而凝固時(shí)間越短，石膏就會更加牢固。

2. The setting time of gypsum is closely related to the amount of water added, followed by the mixing time, temperature and humidity. If too much water is added, the longer the setting time is, the less firm it will be. On the contrary, the shorter the setting time is, the stronger the gypsum will be.

3、添加乳白膠以后，石膏就會變得更加牢固，表面上還會顯得非常細(xì)膩光滑，但石膏凝固時(shí)間就會很長。把石膏填補(bǔ)在墻體中的裂縫中，就要將裂縫填滿，這樣才能適當(dāng)?shù)奶砑右恍┧槭叩[當(dāng)作填充物。填補(bǔ)完成以后再使用刮刀將石膏上的表面層磨平這樣才能和整個(gè)墻面融為一體，這樣看上去非常的美觀。

3. After the addition of milk white glue, the gypsum will become more firm, and the surface will appear very fine and smooth, but the gypsum solidification time will be very long. When gypsum is filled in the cracks in the wall, it is necessary to fill the cracks, so that some gravel can be properly added, and the rubble can be used as filler. After filling, use a scraper to smooth the surface layer on the plaster so that it can be integrated with the whole wall, which looks very beautiful.

此外我們在購買石膏粉時(shí)一定要尋選擇硬度較好的，特別是A級別或特級粉，這樣的石膏粉白而細(xì)膩非常好。在挑選時(shí)先要看下石膏粉的顏色，主要顏色分別是灰色，黃色和白色。而灰色的石膏粉一般都使用到大部分的建筑上面，從而我們可以認(rèn)真細(xì)察石膏粉在浸水以后是否還能發(fā)現(xiàn)里面是否還會黑色小顆粒雜質(zhì)，如果有這種石膏比較脆，價(jià)格也比較便宜。

In addition, when purchasing gypsum powder, we must look for and choose the ones with better hardness, especially grade A or super grade powder. Such gypsum is very white and delicate. When selecting, first look at the color of gypsum powder. The main colors are gray, yellow and white. The gray gypsum powder is generally used in most buildings, so we can carefully examine whether the gypsum powder can still find black and small particles in it after being soaked in water. If there is this kind of gypsum, it is brittle and cheap.

像黃色系列的石膏，大部分都使用到制模，雕塑上，黃色石膏粉它的材料非常堅(jiān)硬，而且制作出的細(xì)目作品也非常精美。您對產(chǎn)品有需求就來我們網(wǎng)站http://www.man5g.cn咨詢了解吧！
