How to solve the problem of putty powder degreasing

If you want to know how to solve the problem of putty powder removing powder, you should first understand the putty powder.

Putty powder is a kind of building decoration materials, usually the whiteness of putty is above 90 and the fineness is above 330. Putty is a kind of base material used for wall repair and leveling, which lays a good foundation for the next decoration. Putty can be divided into internal wall and external wall. External wall putty should be resistant to wind and sun, so it has high adhesive property, high strength and low environmental protection index. Internal wall putty comprehensive index is good, healthy and environmental protection, so the internal wall is not used for external use, and the external wall is not used for internal use. Usually putty is gypsum or cement-based, so the surface is rough and easy to bond firmly. But in the construction, we still need 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 surface.

To understand the basic knowledge and main application fields of putty powder, the next step is to analyze the main components of putty powder if you want to solve the phenomenon of putty powder degreasing. Putty powder is generally divided into external wall putty and internal wall putty. The quality of putty powder is determined according to different raw materials. According to different regions, the main raw materials of putty powder are not the same. The common putty powder for exterior wall is composed of cement, heavy calcium, gray calcium, hydroxypropyl methyl cellulose, redispersible latex powder, etc., while the putty for interior wall is composed of gray calcium, heavy calcium and cellulose. So why some putty powder can cause powder shedding and even large area falling off.

First of all, the role of a mature putty worker is more critical, and skilled techniques play an important role in the construction. Second, whether the mixing is even or not may also be one of the reasons. However, machines are basically used as agitators. Agitators can make materials mix evenly, which is rarely seen in the past. The first two cases are objective reasons, and the supervisor should analyze the raw materials of putty powder. Putty powder de dusting is first related to the amount of calcium ash added. As the construction friends should know, when lime calcium reacts with white cement, it is necessary to add more cellulose to ensure that if too much lime calcium is added, more cellulose must be added. If the amount of cellulose added in the construction is certain, and too much lime calcium is added, the putty powder will be dehydrated too quickly, resulting in de dusting. Therefore, the first consideration for putty powder de dusting is put forward The addition amount and quality of gray calcium and putty powder de dusting are also related to the quality of hydroxypropyl methylcellulose. There are too many brands of hydroxypropyl methylcellulose in the market now, the prices are different, and the quality is also uneven. As we all know, quality determines the price, so Xiaobian reminds you not to blindly look at the price of building materials friends, stable quality, the price is appropriate is a good choice.

Shandong chuangyao Biotechnology Co., Ltd. specializes in the production of redispersible latex powder and hydroxypropyl methyl cellulose. With good quality and excellent service, it is recognized by the majority of building materials friends. Under the supervision of new customers, Yao will grow stronger in the future.
