Carbonized wood is a modified product of high temperature heat treatment of wood. Compared with ordinary wood, it has a series of characteristics:

The dimensional stabilization of wood is a treatment method to change its hygroscopic and hygroscopic properties without destroying the complete structure of the wood cell wall.

What are the hazards of wood blue stain? do you know?The following are the hazards of wood blue stain.

Wood blue stain usually refers to the discoloration of all sapwood in wood, and blue stain is a general term for the discoloration of wood sapwood. In addition to changing to blue, it also includes other color changes, such as black, pink, green, etc. The fungi that cause blue-staining of wood include Cymbidium spp., Ceratosporium spp. and Chromium spp., etc. The most serious damage to rubber wood is Cocoa spp.

Wet wood suitable materials for industrial applications are usually used for low industrial, density, mechanical strength, mechanical properties, perishability, etc., not directly used, practicality and practicality after treatment and drying. It mainly has the following aspects.

After more than 20 days of efforts, the Indonesian customer installed two wood drying kilns by himself according to the drawings, videos and remote installation instructions provided by our company

During the drying process of wood, in the process of water evaporation in wood, due to the different combinations of various water in wood and wood, the properties of water in wood at each stage are different, and the properties of wood corresponding to this are also different. Therefore, in the wood drying process, the evaporation process of water in the wood should be reasonably controlled, so as to improve the drying speed as much as possible on the premise of ensuring the drying quality of the wood.

When wood is drying, the drying defects that often occur in wood drying include: internal cracks, surface cracks, end cracks, bending, shrinkage, charring, severe surface discoloration, and uneven drying.

Whether the sawn timber accumulation is reasonable or not directly affects the dry quality of the wood, and its importance cannot be ignored because the sawn timber accumulation operation is simple and heavy. There are some requirements for stacking operations as follows:

Drying benchmarks for new tree species need to be established. Before establishing new drying benchmarks, it is necessary to understand the structure of wood and its physical and mechanical properties, especially the relationship between wood density and drying shrinkage coefficient, and use the drying benchmarks of tree species with similar properties as a reference. . Or saw small samples and dry them in a drying box to observe their drying conditions. You can also put all kinds of wood to be dried together for drying experiments to observe the drying conditions of various test materials, and then according to various The reaction of sawn timber to drying is carried out by tree species. The steps are as follows:
