添加劑的問題：膩子中最常用的纖維是纖維素醚，主要起保水作用。添加纖維素醚時，應選擇纖維素醚的質量和可靠性，質量較差，膩子水分差，批刮困難。纖維素醚的粘度也適中，粘度太高，批重太重，難以工作，粘度過低，保水量不足，很容易干燥。在灰鈣200Kg的膩子粉，3-4kg粘度4萬羥丙基甲基纖維素。此外，我們可以考慮添加木纖維，便宜，水和增稠劑，并添加少量的淀粉醚增加施工。批量剃須是輕而粘的。

The problem with additives: The most commonly used fiber in putty is cellulose ether, which mainly serves to retain water. When adding cellulose ether, the quality and reliability of cellulose ether should be selected. Poor quality, poor putty moisture content, and difficult scraping. The viscosity of cellulose ether is also moderate. If the viscosity is too high and the batch weight is too heavy, it is difficult to work. If the viscosity is too low and the water retention is insufficient, it is easy to dry. Mix 200kg of calcium ash putty powder and 3-4kg of 40000 hydroxypropyl methyl cellulose with viscosity. In addition, we can consider adding wood fibers, which are cheap, water, and thickeners, and adding a small amount of starch ether to increase construction. Batch shaving is light and sticky.

膩子粉在墻面上的快速干燥主要受外部因素、內部原因和批量刮料厚度等因素的影響。外因主要是墻體干濕程度和天氣溫濕度、光照等。主要原因是原料配比和添加劑配比，配料厚度也影響膩子上壁的干燥速度。

The rapid drying of putty powder on walls is mainly influenced by external factors, internal factors, and batch scraping thickness. The main external factors are the dryness and wetness of the walls, as well as weather conditions such as temperature, humidity, and sunlight. The main reason is the ratio of raw materials and additives, and the thickness of the ingredients also affects the drying speed of the putty wall.

墻面太干燥：如果墻面太干，會吸收膩子內的大量水分，膩子在膩子壁后迅速干透。在這種情況下，在墻上噴灑膩子之前先檢查一下墻面的水分，施工前沒有清水。

Wall too dry: If the wall is too dry, it will absorb a large amount of moisture from the putty, and the putty will quickly dry out after the putty wall. In this case, check the moisture content of the wall before spraying putty on it, as there is no clear water before construction.

溫度過高：溫度高，光線強，水的蒸發速度快，墻后膩子干。特別是夏季，要避免膩子膩子的高溫和光照強度，選擇早晚低溫工作。此外，加入原料時，纖維素乙醚的用量應略有增加，以增加水的潴留，減少水的過量蒸發。

High temperature: High temperature, strong light, fast evaporation rate of water, dry putty behind the wall. Especially in summer, it is important to avoid the high temperature and light intensity of putty and choose to work at low temperatures in the morning and evening. In addition, when adding raw materials, the amount of cellulose ether should be slightly increased to increase water retention and reduce excessive evaporation of water.

膩子質量問題：有的廠家在膩子中使用水泥和石灰，以節約成本。高堿水泥在膩子中的應用會使水化速度過快，造成塑性損失過快，縮短施工工期。硅酸鈣吸水量大。如果加量很大，會在墻上造成干膩子。因此，在配置原材料時，減少或不使用高堿水泥，減少灰鈣的含量。如果沒有特殊目的，一般情況下，普通膩子只需要添加一般150-200kg灰鈣。

Quality issues with putty: Some manufacturers use cement and lime in putty to save costs. The application of high alkali cement in putty can cause excessive hydration rate, resulting in rapid plastic loss and shortening the construction period. Calcium silicate has a high water absorption capacity. If a large amount is added, it will cause dry putty on the wall. Therefore, when configuring raw materials, reduce or avoid using high alkali cement and decrease the content of calcium ash. If there is no special purpose, in general, ordinary putty only needs to add 150-200kg of calcium ash.
