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.墙体太干：假设墙体太干，会吸收腻子里面的大量水分，腻子粉上墙后会干得很快。这种情况下，先要检查墙体干湿度，在上腻子前用水喷淋墙体，待无明水前方可施工。

　　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.温度太高：温度高，光照强，水分蒸发速度加快，腻子上墙后干得也快。特别是在夏季，要避开温度高、光照强的时段批刮腻子，选择在早晚温度低的时间来施工。另外，配料时要把纤维素醚添加量稍微加大一些，增加保水性，减少水分过快蒸发。

　　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.腻子质量的问题：有些厂商为了俭省本钱，在腻子配料中用水泥和灰钙较多。腻子中配用高碱性的水泥，会构成水化太快，招致塑性损失太快，施工时间就缩短；灰钙吸水量很大，假设添加量大，也会构成腻子上墙时干得快。所以在原料配比时，减少或不用高碱性的水泥，减低灰钙的用量，假设没有特殊用途，在普通情况下，普通腻子只需求添加150-200kg灰钙就够了。

　　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.添加剂的问题：在腻子中普通添加多的是纤维素醚，主要是起保水作用。添加纤维素醚，要选择质量可靠的纤维素醚，质量太差，腻子保水差，批刮困难。纤维素醚的粘度也要适中，粘渡过高，批刮起来过于厚重，费力；粘度太低，保水性不够，很容易干。普通在灰钙为200kg的腻子粉中，添加3-4kg粘度为4万的HPMC。另外可以思索加点木质纤维，价钱低价，可以保水增稠，还可以添加少量的淀粉醚，增加施工性，批刮手感轻不粘刀。

　　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.
