Wood floor carbonizing processing method

Abstract

The invention refers to the field of wood floor processing, in particular to a wood floor carbonizing processing method. The method comprises the following steps: (1) pretreatment: cutting wood into the shape of floor to obtain floor planks; (2) heat pressing carbonizing: putting the floor plank into a heat pressing machine for high temperature carbonizing to obtain carbonized wood planks; (3) cooling: putting the carbonized wood planks into the heat pressing machine to be cooled to lower than 160 DEG. C by the cold oil device of the heat pressing machine; (4) finish product producing: withdrawing the cooled carbonized wood plank from the heat pressing machine and executing post-treatment to obtained finished carbonized wood floor product. This method finishes carbonizing and cooling directly in the same heat pressing machine, thus causing the operation to be simple and convenient and the whole carbonizing process to be safe and controllable with higher yielding rate and higher quality of the finished floor product.

Description

technical field [0001] The invention relates to the field of wood floor processing, in particular to a wood floor carbonization processing method. Background technique [0002] Since the floor is prone to warping and deformation during use, it is also easy to be corroded and mildewed, so wood products often need to undergo a series of treatments for the raw material floor used in the production. Floor carbonization treatment technology has the characteristics of good dimensional stability, corrosion resistance, excellent weather resistance, and does not contain any chemical ingredients, does not pollute the environment, and has outstanding environmental protection. , landscape and interior decoration industries are widely used. [0003] At present, the carbonization methods of floors and floors used in China are generally tank type and kiln type. In order to prevent the floor from burning during the high-temperature carbonization process, the tank-type and kiln-type floor ...

AI Technical Summary

Problems solved by technology

Its process equipment investment is large, the production cycle is long (generally takes 2 days), the carbonization process is complicated, the production cost is high, the heat energy consumption is large, the risk is also high, and there are technical difficulties in processing thin floor skins

Moreover, the defects of the floor during the carbonization process are also more serious, such as knots falling off, deformation, cracking, large color difference, etc.

There is also a hot press carbonization method in China, which uses an ordinary hot press to directly heat press and carbonize the floor, but the floor is carbonized in the existing ordinary hot press at a temperature of 160 ° C or above, and the carbonization has not yet been completed. The four sides of the floor have already started to catch fire. At this time, the only way is to use water cooling method to spray the floor to make the temperature of the floor drop below the ignition point.

This carbonization method has a low success rate and a slow cooling rate. The steam generated by the spray is easy to scald the workers. Once it is not properly controlled, it is very likely to cause a fire.

[0004] In addition, after the floor is carbonized by the above methods, the density will decrease, and some mechanical properties will also decrease. For example, the flexural strength, impact toughness and nail holding force of the floor will decrease significantly, which will affect the performance of the floor.
