The improvement in biodurability of thermally modified materials is due to the following reasons. -During the thermal degradation of wood, acidic substances such as acetic acid and formic acid are generated, which affects the metabolic process of decay bacteria in the heat-treated wood, thus enhancing the corrosion resistance.

Attention during the wood drying process: When the wood is first put into the kiln, it is in a low-temperature preheating and humidification process. The dry bulb temperature for low-temperature preheating is generally within the range of 35-45 ℃.

About the wood drying kiln steps and matters needing attention of choose and buy,today for everyone to introduce:

The equipment of a wood dryer is a large-scale device that is widely operated, and the safety issues in the production process of wood dryers should be taken seriously. Production must be safe in order to operate normally. In general, when there is a conflict between safety and production (such as personal and mechanical issues), safety must be the first priority. This experience was exchanged with blood and wealth, and must not be forgotten. In order to ensure safe production, the wood dryer must meet the following requirements:

Firstly, it is necessary to understand a little about the moisture carrying capacity of air. A cubic metre of air at 20 deg. centigrade and 100% relative humidity will hold around 14 grams of water. If you were to heat the same cubic metre of air up to 70 deg. centigrade it would be holding around 400 grams of water at 100% relative humidity.

Unmatched Stability The thermal modification process removes all moisture from the wood cells, making it highly stable and resistant to warping, twisting, and bowing.

The carbonization process of carbonized wood is divided into the following three processes: Step 1: Heat up and dry at high temperature in the cellar Heating up, the kiln temperature rapidly rises to 100 ° C.

Thermal modification is currently the most successful and economically significant wood modification method in terms of industrial promotion and application.

Bamboo chips are one of the raw materials of bamboo products. They are narrow in width and long in length. In order to ensure the long-term durability of bamboo products made of bamboo chips, bamboo chips need to be dried after being cut into corresponding sizes to avoid The moisture inside remains, which makes the bamboo products last longer. But most of the bamboo strip dryers used for bamboo product processing now dry the bamboo strips in the transmission, and the bamboo strips will be deformed after being heated.

Compared with the conventional drying, vacuum wood drying kiln can be achieved under the condition of low temperature rapid drying of wood, and ensure the quality of wood drying, largely avoid the generation of wood shrinkage defects.Through expert analysis to explore the discovery, cypress, for example, above the fiber saturation point, vacuum drying rate for conventional dry 2.34 ~ 2.88 times;While in the FSP, is 2.90 ~ 4.14 times.
