Wood heat treatment, wax injection and dewaxing integrated modification process and equipment

Abstract

The invention discloses a wood heat treatment, wax injection and dewaxing integrated modification process and equipment. The modification process comprises the following steps of: a, tidily stacking dried wood in a treatment tank, and separating the wood by parting strips; b, vacuumizing the treatment tank and maintaining the state for a period of time; c, heating the treatment tank to a certain temperature; d, putting solid wax into a liquid storage tank and heating to melt the solid wax; e, opening a valve for enabling the treatment tank to be communicated with the liquid storage tank, and enabling the wax liquid to flow into the treatment tank; f, pressurizing the treatment tank, and carrying out heat and wax injection combined treatment on the wood; g, relieving the pressure in the treatment tank, and discharging the wax liquid into the liquid storage tank; and h, carrying out secondary vacuumizing on the treatment tank, removing residual wax liquid on the surface of the wood, andpumping wax steam back to the liquid storage tank through a pipeline, thus achieving cyclic utilization of the wax liquid. Through heat treatment and wax injection and dewaxing combined treatment, thedimensional stability, corrosion resistance, weather resistance and the like of the wood can be effectively improved, and high-value utilization of low-quality wood is achieved.

Description

technical field [0001] The invention relates to an integrated modification process and equipment of wood heat treatment, wax injection and dewaxing, and belongs to the technical field of wood modification. Background technique [0002] Wooden material has natural texture and is a good material for people to make household products. However, due to its biological properties, it has defects such as easy moisture absorption and deformation. In recent years, the consumer demand for geothermal flooring has increased. When the geothermal heating system is in operation, the floor will be baked at a temperature above 40°C for a long time. When the heating system is turned off, the temperature will drop sharply. Being in a humid environment for a long time puts forward higher requirements for the dimensional stability, heat resistance and moisture resistance of the floor. Heat treatment can effectively improve the dimensional stability of wood and prevent wood from cracking and defo...

Problems solved by technology

[0005] Aiming at the low production efficiency of the dewaxing process in the prior art and the relatively poor stability of the processed wood, the present invention provides an integrated modification process of wood heat treatment, wax injection and dewaxing, which allows the wood to be processed in an integrated manner. In the advanced processing equipment, heat treatment, wax injection and dewaxing modification are carried out at the same time. This modification not only simplifies the heat treatment process, but also recycles the wax liquid, which not only improves the dimensional stability of the wood, but also prevents the wood from cracking and deforming. , and can effectively save costs, which is conducive to popularization and use
