SPC lock floor is composed of thick wear-resistant layer, UV layer, color film texture layer and base material layer. European and American countries call this kind of floor RVP (rigid vinyl plank), rigid plastic floor. The base material is a composite board made of stone powder and thermoplastic polymer material through high temperature extrusion, and it has the properties and characteristics of wood and plastic at the same time, ensuring the strength and toughness of the floor.

Thermal expansion and contraction of SPC lock floor and problems after paving

Although the installation method of SPC lock floor is the same as that of wooden floor, the grasp of details during the installation process is also different from that of wooden floor. According to existing market research, after SPC flooring is installed on individual construction sites, there will be phenomena such as warping, arching, large expansion joints, and even snapping breaks.

1. The raw material of SPC floor is made of polyvinyl chloride (PVC) and calcium carbonate using advanced technology to heat composite. The production process is different from that of wooden floor, so the thermal expansion and contraction are also different. The existing paving masters are basically The wood floor master does the work on his behalf, using the "general paving method", and does not calculate the shrinkage joint size based on the thermal expansion and contraction parameters provided by the SPC floor manufacturer. If the room is slightly larger, once the reserved gap is too small, especially when the temperature difference between winter and summer is too large, it is very easy to have no space to expand, which will cause arching and warping.

2. In order to reduce costs, use SPC floors with poor quality and low prices, which have poor stability and high thermal expansion and contraction rates. And the loss caused by the "general paving method".

3. The choice of accessories is also in order to reduce costs. Choosing thinner skirting or narrower right angles and beading in specifications will limit the shrinkage space invisibly and bring unnecessary losses.

There is no object in the world that does not expand or contract, and the floor is the same. Regardless of whether the shrinkage ratio is large or small, as long as the size of the shrinkage joint is calculated according to the used floor shrinkage performance, construction site environment, room size, winter and summer temperature, even floors with poor stability can reduce the problem rate to Minimize and reduce unnecessary losses.
