The construction of decorative board veneer is mainly to fix various veneer boards, such as fireproof board, Polaroid board, rich board, precious wood veneer, etc., on the wall, modeling surface, ceiling surface or furniture by inlay or paste. On the surface. The construction of the veneer is usually carried out on the base surface of the wooden board or plywood.
1. Grassroots treatment: leveling is required, and local convex or concave parts are found to be trimmed. The edge line of the base layer should be straight and square, otherwise it is easy to appear out of shape, and the excess part should be trimmed. For the missing place, if the amount of concave in the edge line is not large, it can be straightened with oily putty, such as when the amount of concave is large. , The method of inlaying wood strips can be used, or the base panel can be replaced. If there are dust, glue marks, nail heads, and particles on the base layer, there will be loose adhesion and pitting. Large particles will lift up the veneer and cause bulge, so it must be thoroughly removed or smoothed. At the same time, clean the back of the decorative panel carefully, and pay attention to not let the glue be stained with particles and sundries, and seal the remaining glue after use.
2. Treatment of the veneer facing the mouth: (1) Apply the original edge to the opposite mouth. If two veneer panels are to be spliced on the same plane, it is best to use the original edge of the veneer panel. The original edge is flatter than the manual cut edge. There are many, and there are many fewer defects. (2) The number of pairs should be as few as possible, and the size of the decorative board should be measured before pasting, and arranged according to the original size, with the goal of having the least number of pairs. (3) The counterpart should be arranged in an inconspicuous place. If the height or width of the decorative surface is greater than the size of the veneer, the counterpart should be arranged in an inconspicuous place, generally less than 0.5m or more than 2m. (3) The corners should be straight, the original edge is best, the thin veneer can be directly opposite, and the veneer above 3mm should be chamfered or crimped.
3. Common veneer veneer method: precious wood veneer veneer: precious wood veneer is to paste and press the wood slices of rare wood such as teak on the three plywood. When cutting and pasting, according to the design requirements of the rare wood collage pattern or collage method, the rare wood should be carefully sawed, the sawing path should be straight, and the edges should be prevented from falling apart. There should be 2-3mm planing allowance when sawing. The processing and planing must be very meticulous. Generally, several boards can be sandwiched between two boards in a stack, clamp the boards with a jig, and then planed to the edge of the wood with a plane. When pasting and matching, use a brush to evenly apply the glue on the back and the base surface of the precious wood board. After pasting, wipe off the squeezed glue with a clean cloth, and press on the precious wood veneer with your hands to make the The wood veneer is tightly glued to the base surface, and the wood grain of the rare wood must be symmetrical and meet the requirements of the mosaic pattern when pasting. The gap between the seams should be as small as possible.
Polaroid and Wealthy Board veneers: Both Polaroid and Wealthy Board are made by pressing decorative paper on three plywood. The method of cutting and pasting is the same as that of precious wood. But pay attention to when trimming, the decorative surface of Polaroid and Wealthy board is easy to collapse and fall off at the edge, so that there are some defects on the surface of the edge. Therefore, the planer should be sharp, the force should be even, and the amount of planing should be small each time.
Fireproof board veneer: (1) Cutting: cut according to the size of the veneer, the edge of the fireproof board is easy to chip, so usually use the planer blade of the woodworker to cut the underline of the fireproof board hard to make it Cut at the knife mark. If you need to drive nails or thread screws on the fire board, drill holes in the fire board in advance. (2) Paste: Use quick-drying glue for pasting the fireproof board. Before pasting, use a plastic scraper to evenly scrape the glue on the wood base surface and the back of the fireproof board, and let it dry for about 3 minutes to bond. There must be no deviation and displacement during the pasting process, and it must be successful once. (3) Refurbishment: After sticking firmly, use a planer blade or wallpaper knife to cut the edges, or use a sharp file to file the edges to a 45-degree angle. You can also use fine sandpaper to polish the surrounding parts. When bubbling occurs, you can use electricity While blowing the air to heat the bubbling area, use a wooden block or stick to push it towards the edge.
Thin veneer pasting: Before pasting, it is generally immersed in warm water to slightly moisten it to prevent the veneer from warping. When pasting, use a brush to apply glue on the back and base surface of the veneer. After pasting, spread the glue on the veneer with a clean cloth, and press on the cloth surface with your hands or a wooden block to make the veneer tightly adhere to the base. There are two butt seam treatments when pasting, one is to handle it before pasting, the other is to lap and glue during pasting, and then cut in the middle of the overlap. When pasting a large piece of thin wood, first stick one end, and then gradually stretch to the other end. After pasting, you can use a rubber roller for sequential rolling, or use a dry towel to press it. In order to have better flatness, an electric iron is also used for hot pressing and flattening to make the pasted veneer dry quickly.
