Veneer processing technology and processing device used for density fiberboard

Abstract

The invention discloses a veneer processing technology used for a density fiberboard. The veneer processing technology includes the following steps that S1, the cooled density fiberboard is taken, thewhole density fiberboard is used or sawn and cut into the required breadth size, and sanding is conducted on the surface of the density fiberboard; S2, under the constant-temperature and constant-humidity condition, the moisture content of the density fiberboard and a veneer material is adjusted; S3, the density fiberboard and the veneer material are preheated through an infrared heater; and S4,the preheated density fiberboard and the preheated veneer material in the step S3 are taken out, emulsion coating is conducted on the attachment face of the preheated density fiberboard, the preheatedveneer material is attached to emulsion, the preheated veneer material and the preheated density fiberboard are made to be sufficiently attached, and a veneer panel pre-finished product is obtained.According to the veneer processing technology, sanding processing is conducted on the density fiberboard before veneer processing, cleanness of the surface of the density fiberboard is increased, thesurface of the density fiberboard can be smoother, and therefore sufficiency of attachment to the veneer material is improved.

Description

technical field [0001] The invention belongs to the technical field of density board processing, and in particular relates to a density board veneer processing process and processing equipment. Background technique [0002] Density board is called density fiberboard. It is made of wood fiber or other plant fiber, prepared by fiber, applied with synthetic resin, and pressed under heat and pressure. It can be divided into high-density fiberboard and medium-density fiberboard according to its density. Density fiberboard and low-density fiberboard, density board is widely used in domestic furniture, decoration, musical instruments and packaging due to its uniform structure, fine material, stable performance, impact resistance, and easy processing. There are still various problems in the surface treatment process.

Problems solved by technology

[0003] A kind of melamine-impregnated adhesive film paper direct veneering process disclosed as the authorized announcement number CN110682375A, although it has realized dry flower, wet flower, surface porosity, brightness, bubbling, delamination, non-membrane, tortoise after the veneer problems such as cracking, which improved the appearance quality of the ecological board, but did not solve the existing problems of the existing density board veneer treatment process: the density board and the veneer material are not fully bonded, and the density board and the veneer material are not fully bonded before hot pressing. The moisture content of the veneer material is balanced to make the distribution of the internal moisture content uneven. The moisture content of the density board and the veneer material is affected by the environment during the panel pressing process. This will seriously affect the quality of the veneer decoration, and it is inconvenient The density board and veneer material are limited during pressing, which reduces the stability. Therefore, we propose a veneer treatment process for density board and its processing equipment.
