The main reasons causing the discoloration of wall coverings

First, excessive moisture in the wall after the construction of the base film. The wall of the water content is relatively high. There will be water penetration, the water that penetrates at this time will form a lot of capillary-like holes, resulting in the wall Alkali penetrates through the holes to the wall cloth to corrode the wall cloth. 2. During the construction process, the glue overflows. If the construction is improper, the glue overflows. During the scrubbing process, the scrubbing will also cause discoloration of the wall cloth.
Third, the construction method is wrong In the process of applying the wall cloth, the strength of the wall cloth is too large, and it may cause the waterproof layer on the surface of the wall cloth to fall off at the joint.
Cause the wall cloth to change color and white. 4. If the wall surface is not dried yet, stick the wall cloth if the wall is not dry yet. Because the protective film on the wall is not yet fully working, stick the wall cloth. Extruded water and glue will penetrate the wall, so that the wall, wall and base film, wall cloth will form one, resulting in direct contact between the wall cloth and the wall, the base film will lose its function. Excessive wall surface treatment is not good In the case of base film construction, when the brushing is too thin, the base film cannot form a good protective film on the wall, nor can it be isolated from the wall with alkaline chemicals. Infiltration, discoloration of wall coverings becomes very likely. First, the selected adhesives are not qualified. Many of the adhesive products on the market are basically alkaline or weakly acidic. These products will have certain corrosion on wall coverings. A long time can also cause yellowing of the wall cloth and affect the service life

LINA Kneading-Preforming Integrated Machine

LINA granulating-preforming integrated machine centralizes all functions of a complete granulation line on one independent working platform. The continuous kneading and preforming efficiency is 1-2 times higher than traditional rubber and plastic sheets, pipes and particles production line. With the combination of PLC control system, LINA Pelletizing-cooling Integrated machine makes the granulation process easier, the working area smaller, labor cost lower and maintenance rate lower.

 

 

 

Technical Advantages of LINA Kneading-preforming Integrated Machine

1. Double gas protection + Air isolated functions: Double gas protection design: Within kneading and pelletizing process, material`s physical properties will change due to different temperature zones, the double gas protection design is adopted to achieve the purpose of protecting material`s physical property. This patented technology is used in the general comparison of titanium / aluminum / copper / nickel and other metal alloy formulations.

2. Double gas protection + Air isolated combined technology: Under the technology of air isolated, the oxygen content in mixing chamber is significantly reduced. And with the design of double gas protection, a high air pressure with low oxygen content mixing environment is formed to ensure the material is kneading and pelletizing in a very low oxygen or oxygen-free state. This patented technology is used in high-quality titanium / aluminum / copper / nickel and other metal alloy formula synthesis and granulation, particularly suitable for discolored special ceramic feeding.

 

Value Points:

1. Automation: Continuous kneading and pelletizing.

2. Eco-friendly: No gas masks needed while operating.

3. User-friendly: Quick release design for die head.

4. Modular: Based on user`s demand, manually material feeding can be updated to automatic weighted feeding.
