Production method of wood material for outdoor

Abstract

The invention discloses a method for producing timber used outdoor, which comprises the following steps: manufacturing rectangular plate blanks or performing vacuum carbonization on logs or battens after being dried; manufacturing the logs or the battens into the required shape and the size; performing the appearance treatment by rebating, sanding, grooving and other processes; ,carrying out coating, edge sealing and finished product package to the timber used outdoor, wherein the vacuum carbonization means that in a vacuum carbonized kiln, under the condition that the moisture in the kiln is kept between 70 and 90 percent, the temperature is directly improved to 100 DEG C, then the temperature is raised to be between 140 and 180 DEG C in phases. The method adopts pure physical technology instead of the prior chemical preservation and insect preventing technology of timber for floor and wallboards used outdoor, or outdoor landscape gardens, so the processed timber not only maintains the beautiful texture, but also shows primitive simplicity and is innoxious and harmless, durable and prevents corrosion and insect; and the processed timber can be widely applied to outdoor floor, wallboards for decoration and pavilions and terraces of the landscape gardens.

Description

technical field [0001] The invention relates to a production method of wood for outdoor use. Background technique [0002] Wood has become a new favorite for indoor and outdoor decoration because of its natural, environmental protection, and natural and changeable patterns, such as outdoor wood flooring, outdoor wall panels, and outdoor pavilion wood, etc. However, wood used outdoors is subject to sunlight, ultraviolet rays, rain, etc. It is easy to rot, deform, crack, cause quality problems and is not durable, which affects its use and promotion. Usually, the outdoor wood currently used is generally vacuum impregnated to impregnate some insect-proof and anti-corrosion chemicals into the wood. , In order to achieve the purpose of insect prevention and anticorrosion, but this kind of chemically treated wood has chemical residues, and secondly, it will be emitted and volatilized by rain or time, which is easy to cause pollution and damage to people and the environment.
