Due to its excellent performance, cork flooring is suitable for use in hotels, libraries, hospitals, nurseries, computer rooms, broadcast studios, conference rooms, practice rooms and homes. However, depending on the performance of the rooms, suitable cork flooring types must be selected.
1 preferred category of cork flooring
There are five types of cork flooring as follows:
The first category: There is no covering on the surface of cork flooring. 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 a UV varnish or paint or photosensitive varnish PVA. According to different paint types, it can be divided into three types, namely, high light, matt light and peace light. This is the technology of the 1990s. The surface of cork flooring required by such products is relatively high, that is, the softwood used is relatively pure.
The third category: PVC veneers, that is, PVC veneers are covered on the surface of cork flooring. The structure is usually four layers:
The surface layer is PVC veneer with a thickness of 0.45mm; the second layer is a natural cork decorative layer with a thickness of 0.8mm; the third layer is a cemented cork layer with a thickness of 1.8mm; and the bottom layer is a stress balanced and waterproof PVC layer. One layer is very important. Without this layer, when the material is heat-set during production, the surface layer of the PVC shrinks and shrinks, causing warping of the entire piece of the floor.
This type of flooring is currently favored by consumers in Beijing and Shanghai.
The fourth category; PVC veneer, the thickness of 0.45mm; the second layer of natural thin wood, the thickness of 0.45mm; the third layer is cemented cork, its thickness is about 2mm; the bottom of the PVC board and the third category Water resistance is good, and at the same time, the stress on the board surface is balanced. The thickness is about 0.2mm.
The fifth category: plastic cork flooring, resin cemented cork flooring, and rubber cork flooring.
According to the room can choose categories:
The general family can choose the first and second category, because the first category is the most original, but all of its excellent features can be displayed, the second type of cork flooring, slightly thicker cork layer, pure texture, but the layer is only 0.1mm-0.2mm thick Thin, but soft, high-strength wear-resistant layer will not affect the performance of the cork performance. Although the surface layer is thin, but the use of households is more careful, therefore, will not affect the service life, and easy to lay, as long as the consumer removes the separation paper, they can stick directly to the clean and dry concrete floor.
For shops and libraries with large traffic, the second and third floor types can be used.
Due to the fact that the second and third materials have a thick (0.45mm) flexible wear layer, the sand will be carried to the surface of the cork floor and will not slide after being pressed into the wear layer. When the feet leave the sand, It is popped up without scratching the wear layer, so the flow of people is large, but it does not affect the floor surface.
Exercise rooms, broadcast studios, hospitals, etc. are suitable for flooring made of rubber cork. Their elasticity, vibration absorption, sound absorption, sound insulation, etc. are also very good, but rubber usually has an odor. Therefore, this kind of floor changes its surface and is used on its surface. PU or PUA high abrasion layer as a protective layer to eliminate odor, but also wear.
2. Select floor density:
Cork floor density is divided into three levels 400kg-450kg/m3; 450kg-500kg/m3; greater than 500kg/m3.
The average family is 400kg-450kg/m3. If there are heavy objects in the room, it can be selected slightly higher. In short, the density can be selected as small as possible, because it has better elasticity, heat preservation, sound absorption, vibration absorption and Other properties.
3. Test floor quality
Look at the choice of cork flooring
Whether the sanding surface of the floor is smooth, whether there are bulging particles, and whether the cork particles are pure.
Choose whether the length of the side of the floor is straight or not. The method is: Take 4 same floors, spread it on the glass, or on the flat ground, and see if it fits together.
To test the bending strength of the board, the method is to combine the two diagonals of the floor to see if there is a crack on the curved surface, and if it is not, it is a high quality product.
Bonding strength test.
Put small pieces into open blisters, and find that the smooth surface of the sand becomes chamois-like, uneven surface, then the product is unqualified, and the quality product should have no significant change on the surface of boiled water.
Second, cork flooring maintenance
Maintenance of cork flooring is simpler than other wood floors. During use, sand should be prevented from being carried into the room. Individual sand particles can be carried in without affecting wear. When the sand particles are introduced, they are pressed into the foot and pressed into the elastic layer. When the footsteps leave, it will pop again. Of course, it should be reminded here that it is not appropriate to bring too much grit into the dirt, which will cause flow wear. Therefore, although it will affect the sand grains, it will wear out too much. Therefore, the sand grains brought into the room should be promptly removed, and there is no need to equip it. Vacuum cleaners do not have to worry about moisture, warping, mildew, etc.
For occasions with large passenger flow, after three or five years, if there is wear at an individual location, it can be partially used to make up, that is, to re-apply the coating to the local area. The method is very simple. Gently use sandpaper to polish the worn area and remove it. The scale on the surface, and then gently wipe with a dry soft cloth, re-coating the coating, or covered with polyester film in the local place.
