Single-side surface layer densification processing method and product for wood

Abstract

The invention discloses a single-side surface layer densification processing method and a product for wood. The method includes dipping treatment; a dried board base material is dipped into a dipping tank filled with agents, the dipping thickness of the surface of the board base material is controlled through control of the dipping depth of the board base material into the liquid level of the agents, the agents include urea resin and nano calcium carbonate granules, and the nano calcium carbonate granules enter the pores of the board base material during the dipping. A floorboard produced through the processing method is composed of a densification layer and the board base material, and the lower surface of the densification layer is connected with the upper surface of the board base material. According to the processing method, the dipping thickness of the floorboard is controlled through the increase and decrease of the liquid level height of the agents, only the surface of the floorboard contacts with the agents, therefore the agents are saved; drying after dipping is not needed, and quality problems caused by the dipping and drying can be avoided, processing steps are reduced, and outturn percentage is improved.

Description

technical field [0001] The invention relates to a wood processing method and a product manufactured by the method, in particular to a wood single-sided surface layer densification treatment method and a product. Background technique [0002] The existing wood single-sided reinforcement material processing method is: the veneer that is rotary cut or sectioned (thickness is generally within 2mm), impregnated with reinforcing resin or fireproof agent; and then the treated veneer is glued to the base material above. This method can achieve single-sided strengthening of the product, but there are the following problems: ①The gluing step requires the use of a large amount of glue, which increases the cost; ②The moisture content and stress of the treated skin and substrate cannot be well controlled. This processing method is not suitable for solid wood floors. [0003] For solid wood flooring and solid wood furniture, the existing technology is to impregnate the whole (six surfac...

AI Technical Summary

Problems solved by technology

This method can achieve single-sided strengthening of the product, but there are the following problems: ①The gluing step requires the use of a large amount of glue, which increases the cost; ②The moisture content and stress of the treated skin and substrate cannot be well controlled. This processing method is not suitable for solid wood floors

Since only the surface of the base material is really required for the surface hardness of the wood, a large amount of chemicals will be wasted for the overall impregnation, and only the upper surface of the base material is impregnated, and then the impregnated layer is dried, and the wood is easy to use. Deformation due to uneven stress and quality problems
