Some display methods in the building materials market are not credible, such as soaking the material into the water to show that it is not deformed by water, which is actually misleading. In fact, all the wooden floors can not be soaked in the water, although the quality is in progress. The destructive test of the test will immerse the material in water, but this does not mean that the wood flooring we purchased can withstand long-term soaking.
In order to meet the needs of daily life, the wooden floor has adopted waterproof measures, but the wooden floor still cannot withstand more serious soaking. Because the internal structure of the wood determines its wet-and-drying characteristics, but the shrinkage coefficients of different floors are different, so all wooden floors should be avoided by water soaking. The so-called "not afraid of water" is not equal to "no deformation."
1, water resistance
Poor water resistance will cause significant expansion around the floor, causing the floor to erect. Moisture content is an important factor that directly affects the dimensional stability of the floor. Generally, the moisture content of the wooden floor should be consistent with the local water content. Otherwise, the floor will have different dimensional changes when the environment changes, so we should pay attention to the purchase when buying. Whether the moisture content of the purchased floor meets the requirements of national standards.
2, flame retardant
Since the flame retardant performance of the wooden floor cannot be required to be too high, a simple test method can be placed on the floor surface with a cigarette. After the end of the combustion, the floor is not burned and the non-clearing marks such as no cracks, dark spots, and bubbling are observed. Indicates that the flame retardant performance is acceptable
3, gluing
The solid wood flooring is made of natural wood without any bonding. The solid wood composite floor is made by hot pressing of the adhesive coated surface, so the glue performance is an important quality indicator of the product, which will directly affect the function and life of the product.
4, formaldehyde content
Parquet and laminate flooring contain a certain amount of formaldehyde in the adhesive, which will gradually release into the surrounding environment in a gaseous form. When people are in a high concentration of formaldehyde, the eyes, nasal cavity and respiratory tract will be uncomfortable. Healthy body.
5, wear resistance
The laminate flooring has good wear resistance because it has a wear layer on its surface. The 6000~18000r we saw on the product description indicates the wear resistance, which also corresponds to the content of the corundum abrasive in the wear layer. . National standards stipulate that products above 6000r are suitable for home use, while public places must be above 9000r.
6, paint finish
Different from laminate flooring, the surface of solid wood flooring and parquet is processed by paint. When selecting, it should be checked to be uniform, smooth and smooth. No leaks, no bubbles, no cracks.
The water resistance is reflected by the water absorption thickness expansion index. The higher the index value, the worse the water resistance. When viewing the test report, the water absorption thickness expansion rate index should be less than 10%, with 2% being the best.
The method for detecting the gluing performance of the solid wood composite floor is very simple. As long as the sample of the solid wood composite floor is immersed in hot water of 70 ° C for about 2 hours, if the glue layer does not appear to be open, it is a qualified product.
Peel the parquet or laminate flooring from the floor. If there is a pungent odor and irritating eyes, the formaldehyde content is excessive.
Counterfeit laminate flooring usually has no wear-resistant layer. A simple method of discriminating can use a piece of sandpaper. It can be rubbed about 50 times in a fixed position on the wooden floor. The qualified product will not leave any trace.
Because the use of different raw materials, the wear resistance of the paint is not the same as the wear resistance of the laminate flooring. Do not confuse the two when understanding the product.
