Select several aspects of laminate flooring: First of all, the laminate flooring consists of four layers from the surface to the bottom of the structure. The top layer is a wear-resistant layer, is transparent, feels the touch from the wear-resistant layer, his role is to make the floor wear, which is the biggest advantage of strengthening the floor, generally strengthen the floor are selected more than 38 grams of the three Oxidized aluminum wear layer, there are some good floor selection of 46 grams of wear-resistant layer (but less). Home floor wear-resistant rotation of more than 6,000 rpm is enough, who can not have nothing to play sandpaper floor. There are also dishonest businesses to save money using a smaller gram of wear-resistant layer, so the wear resistance of the floor will be relatively poor. Below the wear layer is a decorative layer (also called decorative paper), which is a piece of paper with various patterns printed on it. That is, we see the pattern of the floor comes from this paper. The quality of the decorative paper itself does not affect the life of the floor, but the clarity and fidelity of the colored paper directly affect the use of the floor, so the design paper is still imported well. There are a lot of floor brands selling a certain number of floors is very expensive because this color paper was bought by them, others do not have a home, they sell very expensive, has nothing to do with the quality of the floor. The color paper should pay attention to how it is resistant to ultraviolet radiation. If it is poor, it is likely that the part of your home window will fade after one year (but it will not affect the use). Below the decorative layer is the substrate layer. Substantially speaking, the substrate is a density board (high-density board), and the density must reach 0.88 or more to be a good substrate. If the density is small, it is easy to get wet and it is easy to be deformed, and high density is not likely to occur in this case. The floor life of wood can be longer. Some small factories that produce floorboards also achieve high density in order to save money. Instead of using good raw materials, they add a lot of urea-formaldehyde rubber (also known as formaldehyde glue) in the production of substrates, which can also make the substrate higher. Density, but it will cause a lot of formaldehyde in the floor, formaldehyde emission exceeded. At present, there are several standards for formaldehyde emission from the floor. E1 environmental protection standards: formaldehyde emission is less than 1.5ml/l, E0 level environmental protection standard: formaldehyde emission is less than 0.5ml/l. The E1 standard is currently the national standard of our country. As long as it is a decent brand, it should be able to do it, but it is very difficult to achieve E0 environmental protection. If your floor meets the E0 standard then his formaldehyde release is less than that of drinking water and can be used with confidence. If someone says that his floor is 0 formaldehyde, there is no doubt that it is deceptive because formaldehyde is everywhere and formaldehyde is released from the woods in the primeval forest. The last layer of glue balance layer, the production of the floor of the business (professional business) rarely fuss over this. Moisture content: The moisture content of solid wood flooring is the most important factor directly affecting the floor deformation. The water content of the purchased floor must be similar to the local equilibrium moisture content. When buying a floor, you must ask a salesperson to measure the floor moisture content. The method is simple: In the exhibition hall, the moisture content of the purchased floor samples is first determined, and then the moisture content of the floor purchased is checked and accepted. If the moisture content of the two floors is only 1% to 2%, the moisture content is suitable for the local laying floor. Wood species: There are many species of wood flooring, including imported wood, domestic materials, valuable rosewood, teak, and popular Ganmong beans, birch, manchurian ash, etc. Because of the different types of flooring, prices vary widely. . When consumers choose the type of flooring, they must choose floorings that are relatively stable and their favorite patterns and colors. Specifications: From the standpoint of board stability, the smaller the floor size, the better the resistance to deformation. For this reason, choose a short, narrow solid wood floor to minimize the bending, twisting, scooping, shrinking, and arching of the solid wood floor. Floor experts believe that short is better than long; narrow is better than wide, and it is cheap. Machining accuracy: After assembling 8 to 12 floors on a flat surface, observe whether the processing accuracy is smooth, smooth, and whether the tongue and groove are suitable or not by hand and eye. Should not be too loose, nor too tight. Material: Use the eyes to see if the floor is the same material and whether the surface of the board is cracked, rotted, peeled, dead knot, bug eyes, blue stain, or other material defects. Usually, color, joints, textures, etc. do not have to be overly demanding. This is a natural property of wood. It is the chromatic, rich and varied natural texture that shows the natural qualities of solid wood flooring. It is the current fashion of home decoration in the world. Quality of paint: After the board has been painted, it is called paint board. When picking, please pay attention to three things and three things. Third, the paint must be even, smooth, and smooth. Three nos: yes no paint, no bubbles, no cracks. After-sales service: Consumers need to consider a series of issues in order to prevent unnecessary troubles while purchasing floors.
