The surface of the coniferous material contains a lot of oil, which tends to reduce the adhesion of the coating on the surface of the wood, so that the coloration is uneven, so the grease must be removed before the coating. Common methods for removing grease include: 1. Allowing the wood to be dried at a high temperature; 2. Scrubbing with 5% to 6% sodium carbonate (Na2C03) or 4% to 5% sodium hydroxide (Na0H) solution (washed with water after treatment) Net, but the wood color becomes darker; 3. Use organic solvents (such as acetone, benzene, etc.) to dissolve the oil; 4. Wood surface paint before applying shellac or polyurethane sealer to separate the grease from the coating To ensure the decorative quality and effect of the coating.
Most woods are uneven in color, and sometimes they are discolored by metals, acids, alkalis, and fungi to form stains. High-grade furniture or high-grade decorative wood, in order to improve the dyeing decoration effect of the wood surface coating, it is necessary to bleach the wood before painting. For example, use 35% hydrogen peroxide (H2O2) and 28% ammonia water to uniformly coat the surface of the wood before use. After about 30 minutes, wash off the residual liquid with water to dry, and achieve better bleaching effect.
The large defects such as knots and decay on the surface of the wood can be repaired by the excavation process. The traditional excavation method uses manual digging or drilling to fill the round blocks, which has low efficiency and poor repair effect. At the Guangzhou International Woodworking Machinery and Furniture Fair in the fall of 2000, the author saw a set of power tools specially designed for repairing wood defects by Lamello, Switzerland. It consists of a slotting machine, a patch making machine and a router. The slotting machine mills out the defects such as knots and decay on the surface of the wood to form "eyelid" shaped pits, and the patch making machine processes the patches for repairing the defects. The glue is used to embed the inserts into the pits, and the upper part is used for milling. The machine is flattened, because the precision of the fitting is high, the naked eye is difficult to detect, the efficiency is high, and the effect is good.
For wood surfaces - some small defects such as cracks, insect eyes, nail holes, etc. can be used to fill the putty. Putty with calcium carbonate, talcum powder and glue, oil, pig blood and various paints, plus human color pigments blended into rubber putty, putty, pig blood putty or shellac putty, nitro putty, polyurethane putty, poly Fatty putty, etc., can be selected as needed. The shellac putty commonly used in wooden furniture is made up of 75% calcium carbonate, 24% shellac paint (15%~20% agricultural degree) and about 1% coloring pigment. The shellac putty is filled with holes and seams. It has fast drying, strong adhesion, easy sanding and good dyeing performance.
If the surface defects of the wood are more serious, you can use the putty to fill the flat. Before the finishing, you can manually attach the decorative paper (30g/m2) with wood grain and color similar to the wood in the defect area, and finish it with the surface coloring process. The effect is also better, and the repairing process is simple and convenient. If a thin layer of wood is applied to the surface of the wood and all defects are completely covered, the effect is better. When the flat board is pasted, the hot pressing and cold pressing processes can be used; if the surface is pasted, the thin wood (0.2-0.3mm) can be used, and the type is faster than the type adhesive, and the manual pressing can also be used; Simple profile parts can also be covered with a layer of thin wood with a vacuum profiler to completely cover the defects.
After the above-mentioned reasonable optimization treatment, the solid wood furniture surface and the high-grade solid wood decorative material can better highlight the advantages of the wood and improve the surface decoration effect and grade of the wood.
