1. Drying stage of wood drying equipment: operate according to the process benchmark requirements, prevent temperature fluctuations in the heat preservation stage, and prevent the temperature from rising too fast when adjusting the benchmark stage;

The wood dryer equipment is a large-scale equipment with various operations, and the safety issues in the production process of the wood dryer should be taken seriously. Production must be safe, and safety can lead to normal production. In the general environment, when safety and production conflict (such as personal and mechanical), the first thing to obey is safety

The end of the wood is dried first due to the rapid evaporation of water. When the moisture of the end is lower than the fiber saturation point, the end cells begin to shrink. When the dry shrinkage stress reaches the strength limit of the wood, end cracking occurs.

Production units usually use the gravimetric method and the electrical measurement method

Carbonized wood is a wood that is subjected to short-term pyrolysis modification treatment at a temperature of 180°C to 250°C in order to improve the dimensional stability and durability of wood in an environment that blocks oxidation and hydrolysis reactions.

Convective drying of wood in gaseous medium.There are two cases: 1. When the moisture content is lower than the fiber saturation point. 2. When the moisture content is higher than the fiber saturation point.

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.
