1、石膏粉为什么在加水后越搅就越稀呢？

1. Why does gypsum powder become thinner as it is stirred with water?

纤维素作为一种增稠剂保水剂在腻子上应用的，由于纤维素本身的触变性，石膏粉中纤维素的加入也导致了腻子加水后产生了触变性。这种触变性是由于石膏粉中组分呈松散结合的结构被破坏引起的。这种结构在静止时产生，在应力作用下拆散。也就是说在搅拌下粘度降低，在静止时粘度恢复。

Cellulose is used on putty as a thickening agent and water retaining agent. Due to the Thixotropy of cellulose itself, the addition of cellulose in gypsum powder also leads to the Thixotropy of putty after adding water. This Thixotropy is caused by the destruction of the loosely bound structure of the components in the gypsum powder. This structure is generated at rest and disintegrates under stress. That is to say, the viscosity decreases under stirring and recovers at rest.

2、济南石膏粉在批刮过程中比较沉是怎么回事？

2. What is the reason why Jinan gypsum powder is relatively heavy during the batch scraping process?

出现这种情况一般用的纤维素粘度过高，有的厂家用20万的来做石膏粉，这样做出的石膏粉因粘度偏高，所以在批刮时出现发沉的感觉。内墙石膏粉建议添加量为3—5公斤，粘度为8—10万。

In this situation, the viscosity of the cellulose used is generally too high. Some factories use 200000 yuan to make gypsum powder, and the gypsum powder produced in this way has a sinking feeling during batch scraping due to its high viscosity. The recommended amount of gypsum powder for interior walls is 3-5 kilograms, with a viscosity of 80000 to 100000.

3、冬天和夏天用同样的粘度纤维素做出的石膏粉和砂浆为什么感觉粘度不一样？

3. Why do gypsum powder and mortar made of the same viscosity cellulose feel different in winter and summer?

由于产品的热凝胶性，决定了产品的粘度随温度的升高会逐渐降低的，当温度超过产品凝胶温度时，产品将会从水中析出的，从而失去粘度。

Due to the thermal gelling property of the product, the viscosity of the product will gradually decrease with the increase of temperature. When the temperature exceeds the gel temperature of the product, the product will precipitate from the water, thus losing the viscosity.

4、石膏粉容易出现开裂、起泡、脱粉等现象的原因？

4. What are the reasons why gypsum powder is prone to cracking, foaming, and peeling?

主要原因基层未彻底干透施工、基底过于粗糙，批荡速度过快、一次施工腻子层过厚，大于2.0mm、腻子粉抛光时间掌握不佳。没有把握好表面和底层之间的干湿时间和水分挥发速度，季节不同基层和表面的干燥时间不同所导致。

The main reasons are that the base layer is not completely dry during construction, the base is too rough, the batch speed is too fast, the putty layer for one-time construction is too thick, larger than 2.0mm, and the putty powder polishing time is not well controlled. The failure to grasp the dry and wet time and moisture evaporation rate between the surface and bottom layer is caused by different seasons and different drying times for the base layer and surface.
