Production process of parquet

The first step: log selection and segmentation of good wood can produce a good floor, the quality of the log is very important to the quality of the floor. The quality control of a good brand starts from the selection of raw wood, and good wood is the basis for producing high-quality floors.

The second step: log rotary cutting and drying This process is used to process the solid wood core board of the multi-layer parquet base material. The quality of the base solid wood core board is inseparable from the quality of the finished floor. The thickness of the rotary cut solid wood core board is about 1.5 mm, and it will take some time to dry after rotary cutting.

The third step: solid wood core board sorting In order to ensure the quality of each piece of 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 sorting staff to the floor. Substrate selection.

Step 4: Core board gluing and arranging The operation of professional gluing equipment can ensure the uniform amount of gluing and improve the working efficiency of gluing. Arranging 8-10 layers of glued thin solid wood core boards in an orderly criss-cross layered arrangement and bonding them together can change the original stretching direction of the wood fibers. It is this step that completely improves the limitation of the expansion and contraction of solid wood.

The fifth step: the core board is hot-pressed and glued; 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. 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: Thickness sanding of the substrate A large-scale fixed-thickness sander is used to sand the surface and bottom of the floor substrate, which can ensure the flatness and smoothness of the board surface, thereby improving the accuracy of the product and providing the decorative surface. Layers of veneer of precious tree species provide a reliable guarantee.

Step 7: Substrate sorting and health care After the initial processing of the floor substrate is completed, it must be carefully sorted by special personnel to remove unqualified products. After high temperature and high pressure, there is a large internal stress inside the substrate, which needs to be left for 15 to 20 days to release the internal stress, so that the substrate is balanced and stable. This process is called nourishment.

The eighth step: the selection of solid wood veneer Multi-layer parquet is mostly used in the dry environment in the north, so the dimensional stability is the key. In order to prevent cracking and other phenomena in the dry heating season, the precious wood veneer on the surface of the big brand parquet is selected one by one by professional quality inspectors, and the moisture content is strictly controlled.

The ninth step: floor slab forming The selected veneer single piece is coated with environmental protection glue and attached to the floor substrate, and then enters the advanced hot press for hot pressing, that is, a qualified multi-layer solid wood composite floor slab is made. .

Step 10: Preserving the floor slab Since the floor substrate is hot-pressed after the decorative veneer is attached, a large internal stress is generated inside the slab. Such a floor slab needs to be kept in a constant temperature and humidity balanced health warehouse. Let it stand for about 20 days to ensure that the quality of the floor is more stable.
