One is that plywood depends on whether it is an authentic product. The makers often sell counterfeit imported plates and low-grade boards for counterfeit high-grade boards, especially for pretending to be international brands such as "Butterfly", "Panda" and "Earth". When purchasing a board, the user must first recognize the trademark, site, grade and anti-counterfeit label on the whole package. After confirming the real, look at the quality. There are many burrs around the inferior board, while the authentic board is neat and smooth, and the interlayer is even and dense, and the board is flat. The color is the same, there are few eye and patch. Particleboard, MDF and Sembili plates are also available in a variety of thicknesses and grades, with price differences. Good plates are not only thick but also have a tight density and are not easily deformed and deformed in water. Second, the quality of the logs depends on whether the quality is reliable. At present, there are a lot of counterfeit logs in the market, especially in the rural market. The means can be described as various, and some of the cedars produced in Jiangxi and Hunan are pretending to be sold in Guizhou fir, and the pines are pretending to be red hemlocks, and some are used to make big changes. The ruler is posing as a standard ruler. When consumers buy, they must open the hijab of the "fake foreign devil" and see the face of "hanging the sheep to sell dog meat", and then buy it after confirming the authenticity. The wood material should be a high-quality material that has been dried and treated. It is not bent and deformed, has no breakage and decay, has small wood grain slope, no resin marks, white spots and honeycomb eyes, and the knot is small and small. Third, the semi-finished wood materials depend on whether the materials are consistent. Some unscrupulous manufacturers use the machine that people like to buy semi-finished wood without painting, doping makes fake, the surface is made of good materials, the back and the sandwich are made of different materials, and even more, let you see that it is good, paying for delivery is a bad This is more fake on wooden floors, wooden doors and windows, wooden wall skirts, wooden lines, grilles, etc. When purchasing such goods, users must check carefully, not only in the inside and outside, but also in the outer layer and the inner core, especially bundles of lines and floors to prevent the middle clips from short materials and differential materials. Doors and windows should be processed with fine joints. They should be used with 榫 joints and less nails. The angle between the thin plates is the shackle or the solid wood covered wire.
