Gypsum powder is often mentioned, the decoration industry gypsum powder as decorative raw materials, what exactly do many people do not know, the following Golden Sample Gypsum Technology High-speed everyone gypsum powder in the end can do what work.
1. Wall leveling:
In decoration, gypsum powder is generally used for basic treatment, such as filling gaps, rectifying Yin and Yang angles, and finding equality for the first time putty on the wall of a blank house. The bonding degree of gypsum is good, and it is not easy to produce shedding phenomenon. Generally, it is not used directly to find peacetime wall surface. Talc powder will also be added to it, otherwise the construction will be inconvenient.
2. Making gypsum cement:
Adding appropriate amount of activator can produce anhydrite cement or cementitious material, which is suitable for the reinforcement of soft soil foundation, wall painting, mechanical model, tunnel support and production of fibre pressure plate, etc.
3. Other roles:
Gypsum powder can be used as expansive agent, anti-cracking agent, self-leveling mortar and composite mineralizer in special cement production.
Gypsum powder is a common kind of wall surface and other basic treatment materials in decoration. It is also a very important basic work.
The use of gypsum powder is also skillful, especially the control of the setting time of gypsum powder: the setting time is mainly related to the amount of water added (additives are also explained), followed by the mixing time, casting container, temperature and humidity. Firstly, the mixing ratio of water and gypsum powder, the more water, the longer the setting time of gypsum, the lower the density and fastness of gypsum, the shorter the setting time, the greater the density and the fastness of gypsum with less water, the higher the fastness, which need to be controlled according to the specific needs of use. Then talk about the mixing time, generally speaking, mixing to the gypsum powder is very uniform can be cast, generally controlled within five minutes, the longer the mixing time, the faster the solidification time of gypsum powder.
