The quick drying of putty powder on the wall is mainly influenced by external factors, internal factors and scraping thickness. The external causes are mainly the dryness and humidity of the wall, the weather temperature, humidity, light, etc. The internal causes are mainly the raw material ratio and additive ratio of putty itself. The batch scraping thickness also affects the monotonous speed of putty wall.

　　1.墻體太干：假設(shè)墻體太干潦擅，會吸收膩子里面的大量水分援奢，膩子粉上墻后會干得很快。這種情況下忍捡，先要檢查墻體干濕度集漾，在上膩子前用水噴淋墻體，待無明水前方可施工砸脊。

　　1. The wall is too dry: Assuming that the wall is too dry, it will absorb a lot of moisture in the putty, putty powder will dry quickly after the wall. In this case, first check the dryness and humidity of the wall, spray the wall with water before putty, and then construct it before there is no clear water.

　　2.溫度太高：溫度高具篇，光照強，水分蒸發(fā)速度加快凌埂，膩子上墻后干得也快驱显。特別是在夏季，要避開溫度高瞳抓、光照強的時段批刮膩子秒紧，選擇在早晚溫度低的時間來施工。另外挨下，配料時要把纖維素醚添加量稍微加大一些熔恢，增加保水性，減少水分過快蒸發(fā)臭笆。

　　2. Temperature is too high: high temperature, strong illumination, faster evaporation of water, and faster drying behind putty walls. Especially in summer, we should avoid batch scraping putty in high temperature and strong illumination period, and choose the time of low temperature in the morning and evening to construct. In addition, the dosage of cellulose ether should be slightly increased to increase water retention and reduce excessive evaporation of water.

　　3.膩子質(zhì)量的問題：有些廠商為了儉省本錢叙淌，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持沛，會構(gòu)成水化太快摆咽，招致塑性損失太快媒敲，施工時間就縮短；灰鈣吸水量很大种功，假設(shè)添加量大透鹊，也會構(gòu)成膩子上墻時干得快。所以在原料配比時共吞，減少或不用高堿性的水泥召期，減低灰鈣的用量，假設(shè)沒有特殊用途铡急，在普通情況下编漆，普通膩子只需求添加150-200kg灰鈣就夠了。

　　3. Putty quality: Some manufacturers use cement and lime and calcium more in putty ingredients in order to save cost. If alkaline cement is used in putty, it will hydrate too fast, cause plastic loss too fast, and shorten construction time. Grey calcium absorbs a lot of water, assuming a large amount of additions, it will also dry quickly when putty wall is constructed. Therefore, in the proportion of raw materials, reduce or not use high alkaline cement, reduce the amount of lime calcium, assuming no special use, in ordinary cases, ordinary putty only needs to add 150-200 kg lime calcium enough.

　　4.添加劑的問題：在膩子中普通添加多的是纖維素醚径露，主要是起保水作用跌蛔。添加纖維素醚，要選擇質(zhì)量可靠的纖維素醚摹菠，質(zhì)量太差盒卸，膩子保水差，批刮困難次氨。纖維素醚的粘度也要適中蔽介，粘渡過高，批刮起來過于厚重糟需，費力；粘度太低谷朝，保水性不夠洲押，很容易干。普通在灰鈣為200kg的膩子粉中圆凰，添加3-4kg粘度為4萬的HPMC杈帐。另外可以思索加點木質(zhì)纖維，價錢低價专钉，可以保水增稠挑童，還可以添加少量的淀粉醚，增加施工性跃须，批刮手感輕不粘刀站叼。

　　4. The problem of additives: cellulose ether is the most commonly added in putty, which mainly plays the role of water retention. When cellulose ether is added, it is necessary to select cellulose ether with reliable quality, which is too poor in quality, poor in water retention of putty and difficult to scrape in batches. The viscosity of cellulose ether should be moderate, too high, too thick and laborious to scrape, too low viscosity, insufficient water retention and easy to dry. Usually, putty powder with 200 kg lime and calcium is added with HPMC with a viscosity of 40,000 yuan (3-4 kg). In addition, we can consider adding some wood fiber, which is cheap, can keep water and thicken, can also add a small amount of starch ether, increase construction, batch scraping feel light non-stick knife.
