Some people say that pure eucalyptus is the best, but it is not. I think the best is the best imported alpine miscellaneous wood substrate. Because the density will be high.
2. Thickness of surface material: the most mature process at present, and the surface material is. It is best to choose the surface material.
3. Paint: The most widely used and best paint in China, there are 2 brands. One is "Jianfu", one of the three major paints in Germany, and the other is "PPG" in the United States.
As long as all these 2 brands are used, they are good. Many only use two or three imported paints, and others use domestic paints.
4. Formaldehyde release: Formaldehyde exists, but it depends on more than less and the size of the release. Ordinary environment, within the E1 environmental protection level (extraction method:
less than or equal to milligram L); The geothermal environment must be within the E0 environmental protection level (zero, not Eu). Extraction: less than or equal to milligram L.
European E0 is equivalent to Japanese F4 star).
5. Product size: conform to the size marked in the packaging box. There is no difference in size and height.
6. Tongue and groove: the surface layer of the tongue and groove is just horizontal grain.
7. Brand: Brand determines quality and after-sales service.

Be sure to buy big brands of parquet, because all the floors of big brand manufacturers are up to standard in environmental protection indicators, (E-0 level); Moreover, the base material of parquet is pure wood, and the base material used for some small manufacturers' miscellaneous floors is not pure wood and cannot be bought. >>>More
Pick the quality of appearance.
Look at whether the color and texture of the surface wood meet the grade standards, and generally there should be no wood defects such as decay, dead joints, knots, wormholes, skin resin capsules, cracks or loose joints, and the perception of wood texture and color should be harmonious. >>>More
On the premise of not considering the price, you can choose solid wood geothermal products, because no matter how high the environmental protection level of solid wood composite products is, even if there is still formaldehyde emission in E0, solid wood products will not consider the problem of E0 or E1, because there is no such thing at all. >>>More
When choosing parquet, we must first select the appearance quality, and generally there should be no wood defects such as decay, dead joints, and wormholes. The color difference of multi-layer parquet is caused by the different growth environment of wood, and the producer can only make it as harmonious as possible with the help of modern technology, in fact, only the surface of artificial materials can avoid the generation of color difference (such as laminate flooring), and the slight color difference of multi-layer parquet can fully show the natural effect of pure wood flooring. Especially in the manufacture of wood surface veneer, it is impossible to make each piece of veneer color difference. >>>More
1. Look at the substrate: the substrate is the core of the destination board, see if there are impurities in the substrate, whether the density is high enough, put 1 small piece of floor in water to soak for 1 night, to see how much the floor will expand, it is best that the expansion rate does not exceed 40%. >>>More
