1. The first type of cork flooring: the cork layer is slightly thicker and the texture is pure. The surface layer is only 0.1 to 0.2 thick. The thin, soft and high-strength wear-resistant layer does not affect the performance of the cork. The wear-resistant surface material is It is non-toxic, tasteless, odorless and durable. It can be pre-painted at the factory. The back of the cork is coated with pressure-sensitive adhesive and coated with release paper. It is extremely convenient for users to use. It can be directly pasted into clean and dry cement by removing the release paper. on the ground. This type of floor user can design and paste it by himself, which is very convenient. In addition, the lacquer surface can also be painted as a whole after the cork floor is paved. This process is widely used in Australia and New Zealand. If you can change shoes in the bedroom, you will not bring sand into it. Generally, the life of 10-15 years is no problem. → Related links: teach you how to check the quality of cork flooring
2. For shops, corridors, and places where traffic is difficult to avoid sand, the second and third types of flooring should be used. The surface layer has a thick flexible wear layer. After the sand is pressed into the wear layer, the sand will not slide. When the foot leaves, the sand will be ejected without scratching the wear surface. This is its advantage; but the surface is non-toxic. PVC, pure PVC resin can not be used as wear-resistant protective layer, it is brittle and easy to age, so plasticizer, heat stabilizer, light stabilizer, anti-blocking agent, antistatic agent, etc. should be added to the formulation, although The floor formulation strictly requires that these additives be non-toxic, but at least the plasticizer is odorous, easily migrates to the surface of the PVC, and is easily leached by the solvent, and may accelerate the aging of the product, so it is not suitable for the bedroom. At the same time, the two types of glued cork layers have been over-compressed, so the functions of heat insulation, sound reduction, shock absorption and the like are deteriorated. At present, some domestic consumers admire foreign products, blindly choose high-priced foreign second- and third-class products, and have doubts about the anti-storage of cheap domestic first-class products. From a scientific point of view, the life of a typical PU coating is about 15 years. The coating should be renewed when the first coating has a life of more than 10 years. The aging life of PVC plastic is not as good as that of PU resin. After aging, there will be hydrochloric acid and chlorine. Ion contamination, therefore, the first type of floor should be preferred for the bedroom floor.
3. Using rubber cork as the floor, its elasticity, vibration absorption, sound absorption, sound insulation and other properties are also very good, but usually rubber has a taste, special high-grade rubber is not economical, and PU or PUA high wear-resistant coating is used as a protective layer. Both performance and price are taken into consideration, as it can be used for residential and indoor sports. → Related links: Cork flooring is divided into five categories to see which type you need
4. Cemented cork or rubber cork is used as the bottom layer of the wooden floor. It not only utilizes the elasticity, heat insulation, sound insulation and noise reduction of cork, but also builds a reliable moisture-proof layer for the wooden floor, which simplifies the paving process of the wooden floor. However, the cork material used must be water and mold resistant.
5. The density of cork flooring products is 400-450kg/m3, 450-500kg/m3 is more than 500kg/m3, and the common intermediate is 450-500kg/m3. If there is no heavy object in the room, the density should be as small as possible, because it has Better flexibility and insulation, sound absorption, sound insulation, vibration absorption and other properties.
