Multi-storey solid wood flooring sold fire exploration camp secret production process

The floor market has always been a two-strong battle, strengthening the floor cheaper and more affordable, elegant and solid wood flooring. In the past two years, solid wood composite floors have risen suddenly, claiming that they not only have the solid wood “face” that the former does not have, but also solve the shortcomings of the latter's love for deformation and difficult care. The mystery lies in the word "composite". So what is compounding in the end? In order to find out exactly what happened, the reporter deliberately went to the production plant of solid wood flooring to observe the production and processing process from beginning to end. Hope that through our display, you can also understand the mystery.

The first step: log selection

A good wood can produce a good floor, and the quality of the log has an important impact on the quality of the floor. The quality control of a good brand starts with the selection of raw materials. Good wood is the basis for producing high-quality flooring.

The second step: peel drying

This process is used to process the solid wood core board for the production of multi-layer solid wood composite flooring. The quality of the substrate solid wood core board is closely related to the quality of the finished floor board. The thickness of the solid wood core board rotated and cut is about 1.5 mm, and it will take some time for drying after the rotary cutting.

The third step: wood core board sorting

In order to ensure the quality of each piece of flooring, regular manufacturers usually choose solid, thin, uniform, moderate thickness, and non-defective, non-breaking solid wood core board as the floor substrate. The full-time sorter will select the floor substrate.

The fourth step: core board glue row board

Professional gluing equipment to operate, can guarantee the amount of rubber evenly, improve the efficiency of gluing. The 8-10 layers of glued thin solid wood core boards are arranged in a criss-cross pattern and arranged in layers, and they are bonded together to change the original stretching direction of the wood fibers. It is this step that has completely improved the limitations of the wet swell and shrinkage of solid wood.

Step 5: Hot-press gluing

Hot pressing is an important process in the production process of solid wood flooring. It is directly related to the quality of finished flooring products. The large-scale factory adopts advanced hot-pressing equipment and production management personnel monitor the entire process, so the product quality is relatively stable.

Step 6: Thickening the base material

The use of a large-thickness sanding machine for sanding the surface and bottom of the floor substrate ensures smoothness and smoothness of the board surface, thereby improving the accuracy of the product, and providing a reliable guarantee for the veneering of the precious tree species veneer of the decorative surface layer. .

Step 7: Substrate Sorting and Preserving Health

After the initial processing of the floor substrate is completed, it must be meticulously sorted by special personnel to remove unqualified products. After high temperature and high pressure, there is a large internal stress inside the substrate, and it needs to be released from equilibrium for 15 days to 20 days to release this internal stress, so that the substrate balance is stable. This process is called health.

Step 8: Picking of solid wood dough

Multi-layer parquet is mostly used in the dry environment in the north, so dimensional stability is crucial. In order to prevent cracking and other phenomena in the dry heating season, the precious wood veneers on the surface of the big brand parquet are all selected by professional quality inspectors. The moisture content control is extremely strict.

Step 9: Floor slab molding

The well-selected veneer is coated with green adhesive on the floor substrate, and then into the advanced hot press machine for hot pressing, which is made into a qualified multilayer solid wood composite floor slab.

Step 10: Floor slab health

Since the floor base material is hot-pressed after being affixed with decorative veneer, the internal stress of the slab also generates a greater internal stress. Such a floor slab needs to stand still in a constant temperature and humidity equilibrium health store for about 20 days. Ensure that the floor quality is more stable.

The eleventh step: floor cutting slot

After health care, the slab will be cut by slotting equipment. The grooving is of great significance to the splicing of the finished floor, so large domestic companies have introduced more German import cutting equipment to ensure quality.

Step 12: Draw paint dry setting

After the slot floor is completed, it will pass the paint dripping equipment. After eight coats of primer and four coats of paint, the surface finish of the finished floor will be moist and resilient. Afterwards, simply sorting the packaging ends the entire production process.
