The first step: Only by selecting materials from logs can a good floor be produced, and the quality of logs is very important 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 floors.
Step 2: Log rotary cutting and drying are used to process and manufacture solid wood core board of multi-layer solid wood composite floor substrate. The quality of solid wood core board is closely related to the quality of finished floor. The thickness of rotary-cut solid wood core board is about 1.5 mm, and it takes some time to dry after rotary-cutting.
Step 3: Sorting of solid wood core boards In order to ensure the quality of each floor, regular manufacturers usually only choose solid wood core boards with uniform thickness, moderate thickness, no defects and no cracks as the floor substrate, and full-time sorters choose the floor substrate.
Step 4: Glue the core board with professional gluing equipment, which can ensure the uniformity of gluing quantity and improve the gluing efficiency. After 8- 10 layers of thin solid wood core boards are glued, they are arranged in an orderly crisscross manner and bonded together, which can change the original stretching direction of wood fibers. It is this step that completely improves the limitation of wet expansion and dry shrinkage of solid wood.
Step 5: hot pressing and bonding the core plate; Hot pressing is an important process in the production of solid wood composite flooring, which is directly related to the quality of finished flooring. The hot pressing equipment used in large factories is relatively advanced, and the production management personnel monitor the whole process, so the product quality is relatively stable.
Step 6: Sanding the substrate with fixed thickness. Sanding the surface and bottom of the floor substrate with a large-scale fixed thickness sander can ensure the flatness and smoothness of the board surface, thus improving the accuracy of the product and providing a reliable guarantee for the bonding of precious bark on the decorative surface.
Step 7: After the primary processing of substrate sorting is completed, the substrate of healthy floor will be carefully sorted by a special person to eliminate unqualified products. After high temperature and high pressure, there is a large internal stress in the substrate, which needs to be released after standing for 15 to 20 days to make the substrate balanced and stable. This process is called keeping in good health.
Step 8: Choose solid wood veneer and multi-layer solid wood composite floor for dry environment in the north, so dimensional stability is the key. In order to prevent cracking in dry and hot season, all the precious wood skins on the surface of big brand solid wood composite floors are selected by professional quality inspectors one by one, and the moisture content is strictly controlled.
Step 9: floor molding: the selected veneer is coated with environmental protection glue and stuck on the floor substrate, and then hot-pressed in an advanced hot press to make qualified multi-layer solid wood composite floor.
Step 10: Floor Maintenance Because the floor substrate is hot-pressed after the decorative veneer is attached, there is a large internal stress in the floor, so it is necessary to maintain the floor in a balanced curing barn with constant temperature and humidity for about 20 days, so as to ensure a more stable floor quality.
Step 11: the floor is cut and slotted, and the floor will be cut and shaped by slotting equipment. The quality of slotting is of great significance to the splicing of finished floors, so many large domestic enterprises have introduced cutting equipment imported from Germany to ensure the quality.
Step 12: spray paint, dry and finalize the design, and the floor with groove passes through spray paint equipment. After eight coats of primer and four coats of topcoat, the surface paint of the finished floor will be wet and tough. After that, only sorting and packaging are needed to end the whole production process.
