Putty powder is a kind of building decoration material, the main components are talcum powder and glue. I just bought a layer of white putty on the surface of the blank room. Usually the whiteness of the putty is above 90° and the fineness is above 330°. Putty is a kind of base material for leveling the wall, which lays a good foundation for future decoration (painting, wallpaper).
Putty is divided into two kinds: putty inside wall and putty on exterior wall. External wall putty can resist wind and sun, so it has good gelation, high strength and low environmental index. The comprehensive index of putty in the inner wall is good, and it is hygienic and environmentally friendly. Therefore, the inner wall is not for external use and the outer wall is not for internal use. Putties are usually based on gypsum or cement, so rough surfaces are easier to bond firmly. However, during construction, it is still necessary to brush a layer of interface agent on the base to seal the base and improve the adhesion of the wall, so that the putty can be better bonded to the base.
components
Putty is generally composed of base material, filler, water and additives. Base material, also known as binder, is the most critical component of putty and mainly plays various functions such as bonding. The most commonly used binders for putty are cement and organic polymers, and organic polymers can be divided into emulsion and latex powder. Cement is a cohesive, durable and cost-effective binder, but has poor tensile strength and crack resistance. Organic polymers can modify and toughen it, thereby improving the performance of putty.
The filler mainly acts as a filling, and the commonly used ones are calcium carbonate, talcum powder and quartz sand. Attention should be paid to the matching use of filler fineness.
Additives include thickeners, water retaining agents, etc. Thickeners and water-retaining agents play the role of water retention, improving storage and construction performance, and cellulose is generally used. Antifreeze is mainly to improve the storage stability of putty at low temperature. Slippery agent and water reducing agent are generally used in high-grade putty to improve the construction performance of putty.
Some also add fibers to play an anti-cracking effect.
Putty powder is a surface leveling powder material for pretreatment of the construction surface before paint construction. The main purpose is to fill the pores of the construction surface and correct the curve deviation of the construction surface, laying a good foundation for obtaining a uniform and smooth paint surface. , let’s take everyone to understand the formulas of various putty powders:
