Processing production technology of blockboard

Abstract

The invention relates to a processing production technology of a blockboard, which is characterized by reforming a pressure planer and a thickness determination technology in a traditional production technology, enhancing the bonding intensity of the blockboard and the utility ratio of raw materials by adopting technical skill measures, such as the mechanized lateral pressing of jointed boards, secondary gumming, blank assembly, and the like and developing novel technical skills of an environment-friendly type bonding adhesive in the production application of the blockboard. The invention adopts the technical skills, such as low temperature, pressure resistance, prolonging pressing time, display with additional drying fingers, and the like, thereby effectively controlling the release amount of formaldehyde to be superior to a provision of the national standard being not larger than 0.5 mg / L.

Description

technical field [0001] The invention relates to a blockboard processing production process. technical background [0002] Blockboard is one of the main materials for making wood-based panels for furniture and decoration. Because blockboard has the characteristics of uniform specifications, strong processability, not easy to deform, and can be pasted with other materials, it is very popular in the furniture industry and decoration users, and is currently widely used. However, the quality of blockboard varies greatly. If it is not selected properly, it is most likely to have problems with project quality and environmental protection. Blockboards with poor production technology affect the use strength and engineering decoration quality, and blockboards that are not environmentally friendly will directly cause room pollution and threaten human health. For this reason, the country has formulated the blockboard standard (GB / T5849-2006) with reference to international standards, ...

Problems solved by technology

[0004] The technical solution adopted in this invention is: for the dried wood, without planing and thickness-setting process, directly use high-precision multi-blade sawing to cut the strips; the panel is spliced ​​by a side press machine, that is, the side presses first and then the panel is assembled. The advanced process technology solves the problems of uneven width of the slats and poor bonding strength of the panels; the gluing uses aldehyde-free environmental protection glue, and adopts technological measures such as low temperature, low pressure, prolonging the hot pressing time, and adding pads for aging. The amount of formaldehyde released has been controlled; the second pre-pressing, second hot pressing, and second sanding molding processes are adopted to fully ensure that the product surface is smoother and flatter
