Does gypsum powder contain formaldehydeGypsum is a kind of calcium sulfate that is insoluble in water and chemically stable. In addition, gypsum powder is non-toxic, non-corrosive and non-irritating, which is likely to cause skin roughness and allergies if exposed to air for a long time.
The role of gypsum powder made into cement mortar. By adding certain exciters, gypsum can be produced, as well as cementitious materials, which can be applied to weak foundations, painting walls, and mechanical model production.
With surface treatment ability. Coating gypsum powder on plaster walls can make the walls smooth, will not produce dust, and will not shrink, will not produce odor, will not crack, and will make the walls look more beautiful.
Walls can be leveled. When decorating, make sure that the base of the wall is flat, and the uneven wall can be repaired with plaster powder. It is especially suitable for straightening the corners of yin and Yang, mending the seams, and is not easy to fall off.
Gypsum powder has anti-inflammatory properties. Gypsum can be converted into soluble calcium salts, which can reduce nerve pressure and reduce vascular permeability. It also has detoxifying and anti-inflammatory properties.
The use of gypsum powder will level the walls. Gypsum powder can fill the gaps in the walls, adjust the yin and yang corners, and also level the walls of the rough house, level the walls with gypsum powder so that they are not prone to fall off.
Making plaster. Cement can be used to make gypsum concrete by mixing it with a certain percentage of exciters, which can also be used to reinforce our bases and to paint the walls.
Preparing the base. Gypsum powder is mainly used to make the foundation, we usually do not use gypsum directly, but to add some talcum powder, so that it can be better used.
Strong adhesion. Gypsum powder has good adhesion, no matter on which kind of foundation, it can be well articulated, therefore, when plastering, no need to add any adhesive, can be directly constructed, one time molding, and later will not produce problems such as hollow drums, cracks and so on.
As a simple arrangement. Painting our walls is delicate, does not produce dust, does not produce shrinkage at a later stage, and looks fresh, no odor, no cracks.
Fireproof. We apply twenty millimeter thick plaster, so it's heat resistant and heat proof for over two hours.
Other uses. It can also be used as an expansion agent, anti-cracking agent, self-leveling mortar, etc., and can be used as a compound mineralizing agent for cement.
