The quick drying of gypsum powder putty powder on the wall is mainly influenced by external factors, internal factors, and batch thickness. The external factors mainly include the degree of dryness and wetness of the walls, as well as the temperature, humidity, and lighting of the weather; The main internal cause is the raw material ratio and additive ratio of the putty itself; The thickness of the batch also affects the drying speed of the putty on the wall.

1. The wall is too dry: If the wall is too dry, it will absorb a large amount of water inside the putty, and the putty powder will dry quickly after being applied to the wall. In this case, first check the dryness and humidity of the wall, spray the wall with water before applying putty, and wait until there is no open water before construction.

2.溫度太高:溫度高,光照強(qiáng),水分蒸發(fā)速度加快,膩?zhàn)由蠅蟾傻靡部?。特別是在夏季,要避開溫度高、光照強(qiáng)的時段批刮膩?zhàn)樱x擇在早晚溫度低的時間來施工。另外,配料時要把纖維素醚添加量稍微加大一些,增加保水性,減少水分過快蒸發(fā)。
2. Temperature too high: High temperature, strong sunlight, faster evaporation of water, and faster drying of putty on the wall. Especially in summer, it is necessary to avoid applying putty during periods of high temperature and strong sunlight, and choose to construct in the morning and evening when the temperature is low. In addition, when adding ingredients, slightly increase the amount of cellulose ether to increase water retention and reduce rapid evaporation of water.

3. Quality issues with Jinan gypsum powder putty: Some manufacturers use more cement and lime calcium in the putty ingredient to save costs. The use of highly alkaline cement in putty can cause rapid hydration, resulting in rapid plastic loss and shortened construction time; Grey calcium has a large water absorption capacity, and if added in large amounts, it can also cause the putty to dry quickly when applied to the wall. So when mixing raw materials, reduce or avoid high alkaline cement and reduce the amount of lime calcium. If there is no special purpose, in general, only 150-200kg of lime calcium needs to be added to ordinary putty.
4.添加劑的問題:在膩?zhàn)又幸话闾砑佣嗟氖抢w維素醚,主要是起保水作用。添加纖維素醚,要選擇質(zhì)量可靠的纖維素醚,質(zhì)量太差,膩?zhàn)颖K?,批刮困難。纖維素醚的粘度也要適中,粘度過高,批刮起來過于厚重,吃力;粘度太低,保水性不夠,很容易干。一般在灰鈣為200kg的膩?zhàn)臃壑?,添?-4kg粘度為4萬的HPMC。另外可以考慮加點(diǎn)木質(zhì)纖維,價格便宜,可以保水增稠,還可以添加少量的淀粉醚,增加施工性,批刮手感輕不粘刀。
4. Problem with additives: Generally, cellulose ether is added more frequently in putty, mainly for water retention. When adding cellulose ether, it is necessary to choose cellulose ether with reliable quality. Poor quality, poor water retention of putty, and difficulty in batch scraping. The viscosity of cellulose ether should also be moderate. If the viscosity is too high, the batch will be too thick and laborious to scrape; The viscosity is too low and the water retention is not enough, making it easy to dry. Generally, 3-4kg of HPMC with a viscosity of 40000 is added to putty powder with a gray calcium content of 200kg. Additionally, it is possible to consider adding some wood fibers, which are inexpensive and can retain water and thicken. Additionally, a small amount of starch ether can be added to increase workability, providing a light and non stick scraping feel.
