Misunderstanding a "small" large floor effect is good, some businesses often advocate, the wider the wooden floor, the better the paving effect; the imported board is bigger than the "big" of the domestic board, of course, the price is also high. But in fact, the production process of wide-width floor is not higher than the narrow plate, and even some will be lower, and the price is obviously unreasonable. Moreover, due to the use of assembling and laying, the wide floor is prone to noise problems due to insufficient flatness of the ground. In the case of thermal expansion and contraction, large wooden floors are more likely to be sewn and rebounded, so the use of wide wooden flooring is not Wise, the usual optimal size is 600 mm or less in length, 75 mm in width and 12-18 mm in thickness.
Misunderstanding 2 Thick floor feels the thickness of the wooden floor does not affect its texture and noise. At present, many manufacturers have introduced thick-type flooring, often the thicker the wooden floor, the more the texture can be increased, and the more noise can be reduced to attract consumers. But from a professional point of view, this kind of propaganda is unreasonable, because for laminate flooring, thickness is not the determining factor of texture and noise, the key is cushion, keel and processing technology.
Misunderstanding 3 "Green Core" is a green environmental protection market. There are many wooden floors that are promoted with "Green Core", thereby playing the banner of "environmental protection". In fact, this so-called "green core" board is just a "green color" added by the enterprise in the middle part of the floor. It is not a "green" product at all. The state has a lot of hard indicators on the environmental performance of wood flooring, and there are also special certification bodies. Only products certified by authoritative professional institutions can be called “greenâ€.
Misunderstanding four "embossed surface" is more wear-resistant For the market's popular "big relief", "small relief", "relief expert" and "embossed surface" and other wooden floors, Professor Gao pointed out that most of these are invisible. . Because the wear resistance is the most important use index of wood flooring, various carvings on the surface will inevitably greatly reduce the wear resistance of the floor, reduce the processing precision, and it is easy to hide the dirt, so that the quality of its use is greatly reduced. Consumers should not simply pursue surface effects when purchasing, ignoring the longevity of the product and the trouble of maintenance.
Misunderstanding five locks on the floor gap is small, the wooden floor is usually a single lock, and later developed into a double lock, three locks, and now there are even more and more locks, the misleading of the business to consumers The higher the number of locks, the higher the quality and the better the quality. However, in fact, the lock joint of the wooden floor is subjected to three kinds of forces such as tensile strength and anti-extrusion, and the more the lock, the smaller the strength of the floor. Whether the wooden floor is firmly connected is not in the number of locks. Generally, a single lock or a double lock is sufficient.
In addition, there are some wooden floor propaganda such as “Nano Antibacterialâ€, “Full Drill†series, “Skin Noodleâ€, “Silk Noodleâ€, “Deep Noodleâ€, etc. The person is at a loss. The above misunderstandings are more about the hype and exaggeration of the business, and it does not mean that the quality of the wooden floor is really good. When consumers choose wooden flooring, they should pay attention to the product specifications or test reports. Compare the performance and price ratio of the products. Also refer to the following four factors: First, the quality of the substrate, which directly determines the scientific performance of the wooden floor. Impact resistance and deformation probability, select the substrate with appropriate density to ensure the service life of the floor; secondly, the wear resistance, the greater the wear layer thickness, the better the wear resistance; then the moisture resistance, which is the thickness expansion ratio of the water absorption The indicator reflects that the higher the index, the worse the moisture resistance is. The final is the amount of formaldehyde released. For laminate flooring, the release amount is not allowed to exceed 1.5 mg/L.
