石膏粉膩子上墻后干得快的解決辦法

來源：http://www.wavc.cn 日期：2023-07-15 發布人：

石膏粉膩子粉上墻干得快主要有外因、內因和批刮厚度等因素影響。外因主要是墻體干濕程度以及天氣溫濕度、光照等；內因主要是膩子本身的原材料配比以及添加劑配比；批刮厚度也影響膩子上墻的干燥快慢。

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.墻體太干：如果墻體太干，會吸收膩子里面的大量水分，膩子粉上墻后會干得很快。這種情況下，先要檢查墻體干濕度，在上膩子前用水噴淋墻體，待無明水后方可施工。寧夏銀石石膏建材有限公司為您提供石膏膩子專用石膏粉

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，水分蒸發速度加快，膩子上墻后干得也快。非常是在夏季，要避開溫度高、光照強的時段批刮膩子，選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。

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.濟南石膏粉膩子質量的問題：有些廠商為了節省成本，在膩子配料中用水泥和灰鈣較多。膩子中配用高堿性的水泥，會造成水化太快，導致塑性損失太快，施工時間就縮短；灰鈣吸水量很大，如果添加量大，也會造成膩子上墻時干得快。所以在原料配比時，減少或不用高堿性的水泥，減低灰鈣的用量，如果沒有特殊用途，在一般情況下，普通膩子只需要添加150-200kg灰鈣就夠了。

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：在膩子中一般添加多的是纖維素醚，主要是起保水作用。添加纖維素醚，要選擇質量可靠的纖維素醚，質量太差，膩子保水差，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的膩子粉中，添加3-4kg粘度為4萬的HPMC。另外可以考慮加點木質纖維，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.
