The first step in the production of solid wood flooring for consumers: the raw wood is divided into good wood to get a good floor, and the quality of the logs is crucial to the quality of the floor. The quality control of a good brand begins with the selection of logs, and good wood is the basis for producing high quality flooring.
Step 2: Solid wood core board sorting In order to ensure the quality of each piece of flooring, regular manufacturers usually only choose solid wood core boards with uniform thickness and moderate thickness, and no defects and no breaks as the floor substrate, and the floor is selected by the full-time sorter. The substrate is selected.
The third step: the professional glue coating equipment of the core board glued board is operated to ensure the uniform amount of glue and improve the working efficiency of the glue. 8-10 layers of coated thin solid wood core sheets are arranged in an orderly and criss-cross layer, and bonded together to change the original direction of wood fibers. It is this step that completely improves the limitations of the expansion and contraction of solid wood.
The fourth step: core plate hot pressing glue hot pressing is an important process in the production process of solid wood composite flooring, which is directly related to the quality of the finished floor products. The hot press equipment used in the large factory is relatively advanced, and the production management personnel monitor the whole process, so the product quality is relatively stable.
Step 5: Thickening and sanding of the substrate The large-scale thick sanding machine is used to thicken the surface and bottom of the floor substrate to ensure the flatness and smoothness of the surface, thereby improving the precision of the product. The layering of the precious tree species provides a reliable guarantee.
The sixth step: the substrate sorting health floor substrate after the initial processing is completed, but also carefully sorted by special personnel to remove the unqualified products. After high temperature and high pressure, there is a large internal stress inside the substrate, and it is necessary to stand still for 15 days to 20 days to release the internal stress, so that the substrate is balanced and stable. This process is called health.
Step 7: The selection of solid wood veneer is mainly used in the dry environment of the north, so the dimensional stability is the key. In order to prevent cracking in the dry heating season, the precious wood veneer on the surface of the large brand solid wood composite floor is selected by professional quality inspectors, and the moisture content control is extremely strict.
Step 8: Floor slab forming The selected veneer is coated with environmentally friendly glue on the floor substrate, and then into the advanced hot press for hot pressing, that is, qualified multi-layer solid wood composite slab . Step 9: Floor slab maintenance Because the floor substrate is heat-pressed after the decorative veneer is attached, a large internal stress is generated inside the slab. Such a floor slab needs to be in a constant temperature and humidity balance health bin. Resting for about 20 days to ensure the quality of the floor is more stable.
Step 10: The floor cutting and grooving has been cured, and the slab will be cut and formed by the grooving equipment. The quality of the slotting is of great significance to the splicing of the finished floor. Therefore, large domestic enterprises have introduced imported cutting equipment from Germany to ensure quality.
The eleventh step: the lacquer drying and setting of the finished floor will pass through the lacquering equipment. After eight primers and four coats of paint, the finished surface of the finished floor will be moist and tough. After that, just sorting the packaging, the whole process of production is ended.
