Cork flooring is known as "pyramid tip consumption of floors." Cork is an oak tree that grows on the Mediterranean coast and in the Qinling region of China. The raw material of cork products is the bark of oak. It is more environmentally friendly and soundproof than solid wood flooring. The moisture-proof effect is also better and it gives people an excellent foot. sense. Cork flooring is soft, quiet, comfortable, and wear-resistant. It can provide great cushioning to accidental falls for the elderly and children. Its unique sound absorption and insulation properties are also very suitable for bedrooms, conference rooms, libraries, and recordings. Shed and other places.
According to local conditions to buy 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, the thickness is 0.45mm; the second layer is natural cork decorative layer and its thickness is 0.8mm. The third layer is a cemented cork layer with a thickness of 1.8mm; the bottom layer is a stress balance and waterproof PVC layer, this layer is very important, if there is no such layer, when the material is heat-set during the production, the PVC surface will shrink and shrink. Warped the entire 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.
1. The first type of cork flooring: thicker cork layer, pure texture, surface layer only 0.1~0.2 thick, thin, soft, high-strength wear layer will not affect the performance of cork performance, its wear-resistant surface The material is non-toxic, odorless, odorless and durable. It can be pre-coated at the factory. The back of the cork is coated with pressure-sensitive adhesive and covered with a release paper. The user is extremely convenient to use, so long as the release paper is peeled off, it can be directly affixed to clean and dry. On the concrete floor. This type of floor user can design his own, paste his own, very convenient. In addition, the paint can also be applied to the entire surface after laying on the cork floor. Australia, New Zealand and other countries use this process. If you can change shoes in the bedroom, do not bring sand into the general life of 10 to 15 years is no problem.
2. For shops, corridors, places where people's traffic is difficult to avoid sand, second and third floor types are preferred. Its surface layer has a thick flexible wear layer, sand particles will not slide after pressing into the wear layer, when the feet leave the sand will be ejected, will not scratch the wear-resistant surface, which is its advantage; but the surface is not toxic PVC, pure PVC resin can not be used as a wear-resistant protective layer, it is brittle and easy to aging, and therefore in the formulation to add plasticizers, heat stabilizers, light stabilizers, anti-blocking agents, antistatic agents, although The floor formula strictly requires that these additives are non-toxic, but at least the plasticizer is odorous, can easily migrate to the surface of PVC, and is easily leached by the solvent, and may also accelerate the aging of the product, so it is not suitable for bedroom pavement. At the same time, these two types of glued cork layers have been over-compressed, and therefore functions such as thermal insulation, noise reduction, and shock absorption have deteriorated. At present, some domestic consumers are advocating foreign products, blindly using high-priced foreign products of the second and third categories, and there are many doubts about the cheap domestic products of the first category. From a scientific point of view, the life of general PU coatings is also about 15 years. The first time the coating has more than 10 years of life, the coating should be updated. The aging life of PVC plastics is not as good as that of PU resins. After aging and decomposition, there will be hydrochloric acid and chlorine. Ionic pollution, therefore, the first floor of the bedroom floor should be preferred.
3. The use of rubber cork as the floor, its elasticity, vibration absorption, sound absorption, sound insulation and other properties are also very good, but usually rubber odor, special high-grade rubber is not economical, but with PU or PUA high wear-resistant coating for protection The layer is balanced both in performance and price, as it can be used for indoor and indoor sports venues.
4. Cemented cork or rubber cork is used as the bottom layer of wood flooring. It not only uses the properties of cork such as elasticity, heat insulation, sound insulation and noise reduction, but also builds a reliable moisture-proof layer for wood flooring, simplifying the laying of wood flooring. Process. However, the cork material used must be water and mold resistant.
5, cork flooring products density 400 ~ 450kg/m3, 450 ~ 500kg/m3 is greater than 500kg/m3 three, generally used in the middle of 450 ~ 500kg/m3, if the room without heavy objects, should be used as small as possible, because It has better elasticity and insulation, sound absorption, sound insulation, vibration absorption and other properties.
Cork floor care:
1. The maintenance of cork flooring is more convenient than other wood flooring. In the process of use, it is best to avoid sand grains being carried into the room, and some sand grains will be carried in and will not wear out the floor. Because the sand particles are carried into the elastic layer under the foot, they will be ejected when the footsteps leave. Of course, here we must remind that it is not appropriate to bring too much dirt into the sand. This will still cause fluid wear. Therefore, the sand grains brought into the room should be removed in time. Generally, vacuum cleaners are not required, and there is no need to worry about warping, mildew, etc. phenomenon.
2. If some parts are worn after three or five years of use, they can be partially used to make up, that is, to re-apply the coating at the local part. The method is very simple. Gently use the sandpaper to polish at the wear and remove the scale on the surface. Then wipe gently with a dry soft cloth, recoating the coating, or apply a polyester film at a partial place.
3, for the surface of the brushed cork flooring maintenance and solid wood flooring, usually six months to fight floor wax on it. Cork flooring with a resin-impervious layer on the surface is as simple as the care of laminate flooring.
