Wall Foaming Problems There are sand-like small bubble bulges on the foamed wall surface. The causes are: Adding too much paint or miscellaneous materials in the paint mix; Paint buckets, brushes, rollers, or spray guns are not clean Before the paint finishes completely dry, moisture penetrates and the paint film loses its adhesiveness; the wall surface before brushing is not cleaned. Solution: Avoid painting in high humidity seasons or in the weather. When brushing, you must wait for putty or first coat of paint to dry before applying a layer; clean the construction environment before the construction of the latex paint, and clean the wall surface.
Wall peeling problems are mainly due to: poor construction workers work skills; putty, paint adhesion properties or poor shrinkage. Solution: First of all, pick a good quality water-resistant putty. These putties have high whiteness, good water resistance, high bonding strength, no peeling, no chalking, no peeling after use, and can solve the wrinkles of wall peeling; at least two or three scrapes of putty are required before painting latex paint; Gypsum powder plus 108 glue can increase the viscosity. Another point, it is recommended that consumers paint special. The interior wall latex paint has high requirements on scrub resistance, and it is easier to contaminate the wall in home life and can be wiped with water at any time. The interior wall paint does not have the anti-sun function, so it cannot be used to paint the exterior wall.
The main reason for the cracking of the wall is that it may be due to the shrinkage of the putty. Before the construction, the putty is not dry enough to scratch the putty, and the second time the putty is not dry enough to paint, causing the putty to dry and shrink. Solution: The construction should wait until the putty is dry and then scrape again. The thickness of the putty should not exceed 2 mm. Rework and repair should be scraped first cracked, and then putty scraper, putty and then painted finish.

HHCMS-200 carbon molecular sieves
CMS-200 is a new kind of non-polar adsorbent specially designed for extracting nitrogen-rich gas from air. It is suitable for separating nitrogen from air. It has a high adsorption capacity for oxygen and can separate nitrogen from air.
The most notable feature of the Carbon Molecular Sieve is its high gas-producing efficiency, especially the preparation of nitrogen with a purity of less than 99.5%.
It is widely used in large air nitrogen making equipment.

Pay attention to
1. The nitrogen production equipment can reduce the adsorption temperature to better show its excellent nitrogen production performance under conditions;
2. Pay attention to low temperature drying and seal preservation during storage;
