First, look - look is to see the seams, look at the appearance of the floor and the substrate. When choosing the floor, first of all, we must look at the processing technology of the floor, such as V-groove floor, V-shaped groove, also known as anti-wood chamfered floor. The V-shaped notch of this floor is printed by color-changing, first look at the color difference, that is, Whether the color is close to the color of the floor, whether the seam is tight or not, it is easy to seep. There is also a U-shaped groove floor. The U-shaped groove floor is also commonly known as a molded floor. The processing technology is more advanced and more beautiful than the V-shaped groove, but the processing is difficult and the precision is high. After viewing the substrate, it is necessary to look at the substrate. The key to the quality of the floor is the substrate. The substrate of the general quality is the primary color of the wood. It is not dyed or waxed. It can clearly see the original color of the substrate. The good substrate fibers are fine and textured, and the groove edges are smooth and not rough.
Second, sniffing - sniffing is a simple method to assess the amount of formaldehyde released from the floor. When you buy, put the slotted opening of the floor under the nose to breathe in. The good floor has a woody smell of wood, and the poor floor has a pungent smell, which means that formaldehyde may exceed the standard. Be careful!
Third, the grinding - the wear resistance of the floor is also an important indicator of concern, into the floor sales area of ​​the floor supermarket or building materials store, the "wearing number reaches 10,000 rpm" promotional slogans abound, but Whether the wear resistance is higher, the better, the consumer is also confused. Many consumers are accustomed to changing the comfortable slippers when entering the door, so the degree of wear on the floor is not very large, and the 4000-ton laminate floor is enough for home use. When buying a floor, it is necessary to consider the number of wear resistance. For example, a living room or office with a high pedaling rate can use a floor higher than 4000 rpm, but the bedroom, bathroom, kitchen, etc. cannot blindly seek "high".
4. Bubbles - just put the block material on the floor and put it in the basin for a few hours to see if the expansion coefficient is too large. The general floor water absorption thickness expansion rate is ≤ 2.5%. It should be noted that all wood Product blister is expanding, as well as water temperature and so on is also the key, the experience of less judgment may have errors, this is only for reference!
