1, fine woodworking plate purchasing skills
When purchasing a blockboard, pay attention to whether its surface is smooth, whether it is warped, deformed, blisters and dents; whether the core strip arrangement is uniform and neat, whether the gap is small, and whether the core strip has decayed, broken, wormholes and Thrifty. Eggs may be present inside decaying wood strips, and insects may easily occur in the future.
Some blockboards cut corners during production: The gap between the solid wood strips is large, so be sure to look at the sun or tap with an appliance when you purchase. If the gap between the solid wood strips is large, it will be white in that position. If the sound changes greatly, it also indicates that there is a hollow inside the plate, so that the overall load-bearing capacity of the plate is very weak, and distortion and deformation may occur during long-term use.
If the plate emits scent of fragrant wood, it means that the amount of formaldehyde released is relatively small; if the smell is very pungent, it means that the amount of formaldehyde released from the plate is much.
We can also look at the phenomenon of no glue and putty around the board. This phenomenon is generally to make up for internal cracks or voids, which means that their quality is relatively poor. When buying, we must be careful. .
2, glue board purchase skills
When choosing plywood, note the following points:
When selecting, ensure that the front of the plywood has clear wood grain, smooth and smooth, no rough, no sense of delay.
Plywood should not be damaged, bumps, hard injuries, thrift and other defects.
Some manufacturers in the production of the two different lines of veneer affixed together to make plywood, so the choice should pay attention to whether the plywood patch joints are tight, there is no uneven phenomenon.
In addition, it should also be noted that there is no degumming or loosening of plywood. When you buy it, you can use your hand to pound all parts of the plywood. If the sound is crisp, it means that it is of good quality; if the sound is boring, it means that the plywood is loose.
For the sake of environmental protection, it is also very necessary to carefully check its formaldehyde emission.
3, decorative panel plate purchasing skills
When purchasing a decorative panel, note the following issues:
1 Recognize the difference between artificial veneer veneer and natural wood veneer veneer. The texture of man-made veneer veneer is straight and the texture pattern is very regular; while the natural wooden veneer veneer has a natural wooden pattern, and the natural variability of the texture pattern is relatively large and irregular.
2 When purchasing, pay attention to whether the decorative panel has a good aesthetic appearance, whether the material is even and uniform, the color is clear, the wood grain is beautiful, whether the texture of the matching board and the parquet can be arranged according to certain rules, and whether the patchwork and the edge of the board are nearly parallel .
3 When purchasing, pay attention to whether the surface of the decorative board is smooth, there are no burrs, groove marks, and planer marks, and the phenomenon of glue penetration and board surface contamination shall not occur. Try to pick a board with no cracks, cracks, or cracks on the surface.
4 Carefully check the glue of the board. The most intuitive method is to use a sharp flat blade to split along the glue layer. If the glue layer breaks and the wood is not damaged, it indicates that the glue strength is poor, and vice versa. Some unscrupulous merchants are now working on the surface layer board, the surface layer of the panel is very thin, but in order to prevent the floor color, they paint the same color on the floor panel as the surface panel, and then paste on the surface panel, due to Poor adhesion of paint and glue, resulting in poor surface bonding strength of the panel, easy to bulge, so consumers can choose to use the blade scraping the surface of the sheet, if you can easily scrape the paint, to prove that the thickness of the panel is basically not up to standard .
5 Note the detection of formaldehyde emission. The choice of density plates is mainly to detect the amount of formaldehyde released from the plates. If the amount of formaldehyde released from the plate exceeds 30 mg/100 g, it is an unqualified product.
