Many consumers have heard that it is waterproof, moisture-proof, anti-corrosive and will not be deformed when it comes into contact with wood-plastic integrated wall. But in fact, it is unscientific to say that the material of wood-plastic is never deformed. Under some special conditions, the wood-plastic wallboard will be deformed. Otherwise, at the beginning of this material, scholars could not do anything to study how to improve the performance of this material. Bamboo and wood fiber integrated wall manufacturers will always have some methods to change the shape of the material, to make various attempts, and then there will be more mature wood-plastic materials.

 

However, for some people, "the wood-plastic integrated wall has a contraction ratio of three thousandths, thermal expansion and contraction, and there will be a deformation of 3cm in 1000cm. If this continues, there will be a big gap in the future." I don't agree with the statement. And what is the truth?

 

Thermal expansion and contraction, which considers the effect of temperature on the integrated wall surface of wood-plastic.

 

Wuxi Xiqiao integrated wall as the creator of the operation, with 11 years of accumulation and accumulation, is superior to other brands in strength, research and technology.

 

It is reported that this year, the integrated wall company is strongly recommending various second-generation, third-generation and other series of products, and Wuxi Xiqiao will still dare to be the first strong energy and pragmatic energy of the world as a powerful promotion. weapon. With the integration of the wall gradually became known, and then into the thousands of households, most of the consumers only use the integrated wall for the guest bedroom, and resist the use of kitchen and bathroom space, many consumers have not much thought about the wide response, one Some are unfamiliar with the integrated wall decoration of the kitchen and bathroom, and others are for computational considerations.

 

How to resist the recent situation, the industry reflects that this is only a transition period, there is no first-class brand, no first-class product is a zero, Wuxi Xiqiao integrated wall launched in 2015, the Internet + the unit with the assembly room In the concept of 2.0, and following the product development strategy of the collection room, the third generation super integrated wall was launched.

 

In March, Wuxi Xiqiao integrated wall spring and summer new product launch conference launched the European-style Buckingham Palace, program home - Mu Yin Mansion, got an amazing echo, overturning our understanding of the integrated wall. With the constant expansion of the integrated wall surface of Wuxi Xiqiao, it is a matter of course that the integrated wall work is the most costly.

 

Yes, rigid PVC has a shrinkage ratio, molding shrinkage: 0.1-0.5%, heat distortion temperature: 70 °C. Probably the three thousandths mentioned above is based on this.

 

But don't forget, the wood-plastic integrated wall surface is a new type of composite material which is made of PVC and wood fiber and other main raw materials, supplemented by appropriate processing aids, and prepared by hot pressing process. More.

 

Since the source of suspicion is from PVC, let's first take a look at the changes in the shape of PVC in wood-plastic products.

 

PVC has no fixed melting point, starts to soften at 80-85 °C, becomes viscoelastic at 130 °C, and begins to transform into a viscous flow state at 160-180 °C; it must be fused with wood fiber and other raw materials, and the production temperature will not be lower than 130 degrees. Indeed, the PVC heat distortion temperature is 70 ° C, but the indoor temperature is generally difficult to exceed 45 degrees, it is difficult to reach the point of deformation.

 

It was found that the treatment of wood powder with silane coupling agent increased the interfacial compatibility between wood powder and PVC and improved the mechanical properties of the material. The tensile fracture surface of the wood-plastic composite with added compatibilizer was observed by scanning electron microscopy. The composite material with the addition of compatibilizer was determined. The interface between the wood fiber and the plastic was blurred to form a certain thickness of the interface layer. better. It can be obtained by thermal analysis that the wood fiber treated with the compatibilizer has higher thermal stability than the untreated wood fiber, and the addition of the wood fiber increases the thermal stability of the matrix. Some lubricants also reduce the expansion rate of wood-plastic products.
