Gypsum powder how to adjust the solidification of slow
Gypsum solidification time usually depends on the standard of gypsum powder, the standard of high general solidification faster. If you want to slow down the solidification speed of gypsum, you can use cooler water with lower temperature when adding gypsum powder to water, the cooler the water, the slower the solidification speed. The cooler the water, the slower it will set. On the other hand, if you use hot water, it will set faster. If you think this approach does not work, you can also add citric acid or first in the gypsum powder mixed with putty powder, in the water mixed with 108 glue white latex and cellulose, and then blend.
What is the difference between gypsum powder and putty powder
1, gypsum powder is generally used to do grass-roots treatment, such as filling gaps, yin and yang corners straightening, the first putty of the rough room wall leveling. Use to make putty for wall leveling, not directly using gypsum powder, which will also add some talcum powder, otherwise the construction will be less convenient.
2, usually putty is gypsum or cement-based, so that the surface is rough easier to bond firmly. But in the construction of the grass-roots level should be painted a layer of interfacial agent to seal the grass-roots level, at the same time can improve the adhesion of the wall, so that the putty can be better bonded to the substrate.
3, putty powder has a finished product, there is also the site of their own modulation, they are a large area leveling with, it can not be too large a thickness at a time, putty layer of strength is not as fast as gypsum powder, the general hardness is not as high as gypsum powder, so the general use of the surface.
Article Summary: The above is a small introduction to the gypsum powder how to adjust the solidification of the slow content, I hope to help some friends in need.
