Cork flooring is divided into two categories according to the paving method:
The first category: suspended cork flooring
The second category: pasted cork flooring
Cork flooring is divided into six categories according to product structure as follows:
The first category: the surface of the cork floor without any cover, this product is the earliest.
The second category: coating on the surface of cork flooring. That is, the surface of the cemented cork is coated with UV varnish or paint or photosensitive varnish PVA. According to the different types of paint, it can be divided into three types, namely, high light, matt and flat light. This is the technology of the 1990s. These products require a relatively high surface for the cork flooring, that is, the softwood used is relatively pure.
In recent years, there have been products using PU paint. PU paint is relatively soft and can penetrate into the floor and is not easy to crack and deform.
The third category: PVC veneer, that is, the surface of the cork floor covered with PVC veneer, the structure is usually four layers:
The surface layer is made of PVC veneer with a thickness of 0.45 mm; the second layer is a natural cork decorative layer with a thickness of 0.8 mm; the third layer is a cemented cork layer with a thickness of 1.8 mm; the bottom layer is a stress balanced and waterproof PVC layer. A layer is very important. Without this layer, when the material is thermoset during production, the PVC surface shrinks and shrinks, which will warp the entire floor.
This type of flooring is currently favored by consumers in Beijing and Shanghai.
The fourth category; PVC veneer, thickness 0.45mm; the second layer is natural thin wood, the thickness is 0.45mm; the third layer is cemented cork, the thickness is about 2mm; the bottom layer is the same as the third type of PVC board It has good water resistance and balances the stress on the board surface. Its thickness is about 0.2mm.
The fifth category: plastic cork flooring, resin bonded cork flooring, rubber cork flooring.
The sixth category: multi-layer composite cork flooring, the first layer is the lacquer wear layer, the second layer is the cork solid wood layer, the third layer is the solid wood multi-layer board or the HDF high-density board layer, and the fourth layer is the cork balance mute. Floor.
