The plates that are involved in home decoration mainly include: large core boards (ie blockboards), fir finger boards (also known as fir integrated boards), veneers, fire boards, etc. Due to the large variety of plates in the market and the uneven quality, the price difference is particularly large. To prevent the occurrence of shoddy cases, we need to master some basic methods of identification.
(1) How to identify quality Daxin board. Daxinban's technical term is called blockboard, which usually consists of two layers of plywood. The middle piece of small wood is pressed together by mechanical splicing. Because of the gap in the core material, it can resist heat expansion and contraction, and is not easily deformed. . The standard specification of the big core board is 2440mm×1220mm, and the thickness is 12mm, 15mm and 18mm, which has greater hardness and strength. The total thickness of the veneer on both sides of the high-quality big core board should not be less than 3mm; the same sandwich must be the same tree species or physical properties close to the wood splicing, does not allow softwood, hardwood mixed splicing; plate must be dry, moisture content in 6 Between % and 12%, glue and bubbling are not allowed, the surface of the board is flat, and there is no natural bending; the board core is even and uniform, and the splicing is tight. Generally, the quality of the inner core is checked, and the sawing can be accurately identified. Smell smell, smell the side of the glue, if there is a strong odor to stimulate the smell and the eyes, indicating that the environmental standards of the plate is not up to standard, the lower the formaldehyde emission, the smaller the smell, the smaller the better the stimulating taste. The side and back sides of the board shall be marked with a clear, fade-free mark 30 mm from the edge of the board. The content includes the category, production date, manufacturer's code, and inspection code. If it is a paper sticker, it is not a national standard.
(2) How to identify high-quality Chinese fir fingerboards. The specifications of the finger joints of Chinese fir are the same as the blockboards are all 2440mm x 1220mm, and the thickness is 18mm, 15mm and 12mm. The fir finger joint boards are generally made of high quality Chinese fir, peeled, trimmed, mechanically flattened and joined together with blockboard. The difference is that the fir fingerboard does not have a glue layer, so it is relatively environmentally friendly and suitable for making furniture. The method of identifying the finger-joint plate of Cunninghamia lanceolata is basically the same as the method of identifying the blockboard. The plate must be dry, the moisture content is between 6% and 12%, the surface of the plate is smooth, not rough, and there is no natural bending (the surface of the finger-joint plate of Chinese fir may have Some of the natural frugality is determined by the natural properties of the wood; the cores are neat and even, and the splicing is tight. A clear, fade-free mark shall be made on the side and back of the board 30 mm from the edge of the board, including the type, date of manufacture, vendor code, and inspection code.
(3) How to identify high quality veneer. First of all, we have to identify the artificial veneer (also known as technical wood) and natural veneer. In general, artificial veneer textures are straight, regular, and uniform in color. Natural veneers, on the other hand, have natural variations in texture patterns and irregularities (each plate is different), with subtle natural color changes.
Secondly, the appearance of the decorative panel is better, the quality of the finished panel is fine and uniform, the color is clear, the wood grain is beautiful, the wood color is similar, the technology board texture is arranged according to certain rules, the texture is clear, the color is the same, and the surface of the panel should be smooth and smooth. Scratches, no scars.
Third, high-quality decorative veneer glued structure is stable, there is no open plastic phenomenon, veneer and the substrate tight seams, no bubbling, delamination phenomenon, you can use the knife rake method to test the bonding strength, with a sharp blade along the glue layer split, if the glue The layers were damaged but the wood was intact, indicating poor bonding.
Fourth, smell the smell. If the irritating odor is strong, it means that the amount of formaldehyde released is excessive and it will seriously pollute the living environment. In the lower right corner of the general plate, there are regular manufacturer's products marked with the category, grade, and manufacturer's name.
(4) How to identify high-quality splints. The standard specifications of plywood and veneer are the same as that of joinery. Plywood, also known as plywood, usually has a thickness of 3mm/5mm/9mm/12mm, which is what we often say: three centimeters, five centimeters, nine centimeters, and twelve. PCT board. There are front and back splints, high-quality splints are smooth and smooth on the front, not rough, flat on the surface, consistent in texture, uniform in color, and good in gluing quality. There is no degumming and no void phenomenon. We can use a wooden stick about 50 centimeters long. The plywood stands up and gently taps on all parts. The sound is even and crisp. It is basically a fine splint. If a “shell†sounds dull, it is likely to be due to the inherent quality problems caused by degumming and airspace. Splints should not be damaged, wormholes, rows of nail holes, dead knots, burr groove marks and other defects. (5) How to identify high-quality fire board. Fireproof board is a kind of relatively expensive decorative board. Its surface material is an interior decoration facing material produced by impregnating kraft paper in the resin and subjecting to high temperature and high pressure treatment. The surface protective film has heat resistance, fire resistance and water resistance. The characteristics are therefore called fire prevention boards. The choice of fireproof board depends on whether the color and texture of the whole board surface are the same, whether there is color difference, whether there is any flaw, and whether there is any unevenness or blistering by hand. The thickness of high-quality fireproof board has several specifications of 0.3mm, 0.6mm, 0.8mm, 1mm, etc. The thickness is too thin and its waterproof and fireproof effect is correspondingly poor. Therefore, the fireproof board with the thickness up to standard and the same thickness is the high quality fireproof board. There are several characteristics of poor fire board: uneven color, color is simple, fragile, explosive cracks, such fire board heat, acid and alkali resistance, wear resistance is also relatively poor.
