Embodiment Construction

[0024] The production method of outdoor timber of the present invention will be further described in detail below.

[0025] The present invention first makes rectangular slabs or logs or boards and dries them, then vacuum carbonizes them, and then makes them into the shape and size of outdoor floors, outdoor wall panels or outdoor garden wood, and then goes through grooves or sanding or Appearance treatment, painting, edge banding, and finished product packaging of the slotting process can be used to obtain outdoor wood. Drying is to control the moisture content of the slab or log or plank to less than 18%.

[0026] Wherein the vacuum carbonization treatment comprises the following steps:

[0027] a. Stack the slabs or logs or planks and put them into the vacuum carbonization kiln;

[0028] b. Close the kiln door, and directly raise the temperature to 100°C under the condition of keeping the humidity in the kiln at 70% to 90% in a vacuum state of 0.20 to 0.25 bar;

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.
