>>> Analysis of the three main categories of cork flooring
Most of cork flooring uses bark of oak, which has better sound insulation and moisture resistance than solid wood flooring. It also has a soft foot and is not easily deformed. The accidental fall of the elderly and children can provide a great cushioning effect, and its unique sound-absorbing effect and insulation performance are also very suitable for bedrooms, study rooms, children's rooms and so on. How to choose and maintain cork flooring?
Look at the appearance
After the cork bark is peeled, it is divided into three grades (A, B, C) according to the thickness and color purity of the bark, and the price difference of raw materials for each grade is 50%. Cork is a pure natural product from nature. After the floor is made, it naturally has some pits, which does not affect normal use. Westerners prefer nature. However, if some products because of poor raw materials, pitting phenomenon is too serious, the use of artificial make-up putty to fill the pit, the density of putty materials and cork is completely different, after a period of use of thermal expansion and contraction putty will burst out, The floor was completely destroyed.
Cork flooring cork substrate identification only need to see the back of the floor material particle size and black spots. All the small particles and black spots are the most used mixed bark wastes on the surface of the bark. The base material of such wastes has a great influence on the softness and quietness.
After making the floor, the consumer can judge the grade of the raw material according to the color of the floor surface. The surface with whiter color with a little natural color is basically a class A plate, and the darker ones are generally class B or C.
See MDF and lock
The MDF of the lock-type cork floor is the most important. The MDF of the good floor is made of poplar and cypress. The branches are not used, the dead tree is used as the substrate, and the bark is peeled off. Craftsmanship, and high density, use good environmentally friendly triads, but as consumers, we cannot discern, and we can see the density from the cross section. In addition, we can also smell the cross-section, good wood flavor, poor pungent odor.
Another standard for the quality inspection of density plates is the density. The good density plates are all at 900kg/m3, which belongs to high density plates. Nowadays, most of the flooring used in the market is MDF, which has a large difference in expansion rate, waterproof performance, and high-density board. Consumers can judge whether they are good or bad by weight. A comparison of weights can tell whether it is a high-density board. There are two key indicators for MDF inspection: formaldehyde emission and water thickness expansion.
Squat the floor, pay attention not to cut but to rake (so that the section is not neat to facilitate observation), see whether the section is whiter, whether the substrate is uniform, and whether there is any impurity. If black, there are impurities, it shows that there is no peeling bark and washing process, but also depends on the wood fiber does not grow long, otherwise there is a miscellaneous wood.
Feel
Generally good cork gives a warm and thick feeling, and the brightness is also high. This is due to the presence of a softwood airbag. If the feel is colder, the quality is worse.
Smelling cork
When consumers purchase cork flooring, they can smell the flavour of the plate. If it is a woody fragrance, it means that the quality is good. If it is an eraser or a formaldehyde, the environmental performance is not up to the standard.
Feet feeling
Cork contains 42 million very smiling softwood cells per square meter, making it very resilient. Feet are very comfortable and non-slip.
Listen to the sound
Cork is born with a bubble-like cell structure that absorbs the sound of walking and objects striking the ground.
Maintenance of cork flooring is mainly prevented by the following 5 points:
1. Put the furniture on the floor 24 hours after the floor is installed, and minimize the walking of the staff within 24 hours. When you are away from home, please close the windows and doors, especially the faucets, so as to prevent the rain and drip from soaking the floor.
2. The maintenance of cork flooring is more convenient than other wood floors. In the process of use, it is best to avoid sand particles being carried into the room, and some sand particles will be carried in, and it 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.
3. If wear is found in individual areas after three or five years of use, 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 abrasive paper to 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.
4, 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.
5, to prevent heat damage. Avoid hot items such as hot water cups directly on the floor to avoid scalding the surface paint film. At the same time, the sun should be avoided for a long period of time directly on the floor, so as to avoid premature cracking and aging of the paint film after long-term intense irradiation of ultraviolet rays.
