The main reason is that the putty layer is hollowed and foamed. The main reason is that there is gas between the base layer and the putty layer, and why the air does not diffuse into the normal layer and diffuse into the base layer, but appears in the middle. The main reasons are as follows: : improper treatment of the base layer, so that the contact between the putty layer and the base layer is not tight enough to form an interlayer; there is a dense layer between the base layer and the putty layer, such as interface agent or wall solid without water for interface treatment, so that the air cannot diffuse normally to the base layer. Solution: If the wall bubble or empty drum is small, it can be treated by sanding and then treated with wall solidification, and then scraped; if the wall is large, it has caused large area to fall off, it is recommended to use all the walls after eradication. Solid treatment, then batch scraping.

HPMC plays multiple key roles in detergent production: thickening to improve texture, stabilizing suspensions of granular ingredients, emulsifying oily components, forming protective films for moisturizing, and serving as controlled-release carriers for high-end formulations.

Putty plays an indispensable role in wall decoration. Whether it is interior or exterior walls, putty is an important material to ensure that the wall surface is flat, smooth and beautiful. However, compared with interior wall putty, exterior wall putty has some unique functions due to its special use environment and functional requirements.

In the field of building decoration, putty is the basic material for wall treatment, and its performance directly affects the final decorative effect and wall service life. Hydroxypropyl Methylcellulose (HPMC), as a key additive in putty, plays a pivotal role in the construction and functionality of putty. Today, let's talk about the application of HPMC in putty and the analysis of common problems.
