How about integrated wall decoration materials? Does it expand and contract?
Thermal expansion and contraction must be the effect of temperature on the overall wall. Temperature directly affects shrinkage, especially for rigid PVC with shrinkage. The shrinkage of the molded PVC is about 0.1-0.5%, and the thermal expansion and contraction temperature is 70°C. In other words, the above three thousandths are based on this.However, we may ignore that the integrated wall is a new type of composite material with many different materials, such as bamboo powder, wood fiber and calcium powder, plus appropriate processing aids and hot pressing. If raw materials are to be fused together, they must withstand high temperatures. According to the survey, the temperature during the pressing process can reach 130 degrees. Relevant data: The thermal expansion and contraction temperature of PVC is 70°C, but the indoor temperature is usually difficult to exceed 45 degrees, and it is difficult to reach the temperature of thermal expansion and contraction. It can be said that we need not worry.
In addition, the amount of calcium powder and wood powder in the integrated wall is also a factor that affects the performance of the integrated wall. In addition to improving the performance of the monolithic wall from the formulation, the thickened or porous hollow structure currently used in the monolithic wall itself is also an anti-expansion method.
The performance of the product should be considered as a whole, not from the performance of a certain raw material. Therefore, we should treat some so-called hearsay evidence correctly. At present, the integrated wall industry has gradually been accepted by the public. Of course, many peers will fight against it in other ways. As long as it is true, it will naturally be resolved.
