Wood modification is the process of improving the properties of wood. It uses chemical, biological or physical media to act on the wood to enhance the desired properties of the wood during the service cycle. In addition, the modified wood itself should be non-toxic during the service cycle and not release any toxic substances during or after the service cycle.

How to prevent and control the blue of wood? Is there a good way?

After a year of communication and understanding, a customer from Cameroon placed an order with us for 9 sets of 100 cubic meter all aluminum alloy drying kilns and a 6-ton hot water boiler. We received the customer's order in early September and entered into intense production.

To meet the needs of different customers, the control system of drying kilns is generally divided into two types: fully automatic and semi-automatic. As of now, fully automatic control systems have become the trend. Our company has independently developed domestically produced fully automatic control systems and M800, M828 and other systems produced for Italy's HOZMEISTER company for customers to choose from.

The temperatures employed in wood drying kilns typically kill all the fungi and insects in the wood if a maximum dry-bulb temperature of above 60 °C is used for the drying schedule. This is not guaranteed in air drying.

Generally speaking, products produced by drying kiln equipment manufacturers should be distinguished from hardwood drying kilns, cork drying kilns, furnace gas heating drying kilns, etc., and should not be confused. In practical operation, the company should master different drying processes for different tree species and specifications of wood, and provide the following training: explain wood knowledge, drying knowledge, and methods for controlling moisture during wood drying to customer factories. Assist customers in mastering scientific drying processes, reducing errors during the drying process, and improving economic benefits.

The heating equipment for wood drying kilns mainly includes the following types: 1. Boiler: Boiler is one of the commonly used heating equipment in wood drying kilns. The boiler transfers the heat energy generated by fuel combustion to the air or thermal medium inside the drying kiln, in order to increase the temperature inside the kiln and achieve the drying effect of wood. Common types of boilers include coal-fired boilers, oil fired boilers, gas boilers, etc.

Factors Affecting Wood Drying Speed The main factors affecting the drying speed of wood are medium temperature, humidity, air circulation speed, wood moisture content gradient, and temperature gradient.

Moisture in wood can move inside the wood under certain conditions, which is called moisture conductivity of wood. Moisture can drain from both ends of the wood by moving along the fiber direction, or it can drain from the sides of the wood across the fiber direction, and in most boards, the length is much greater than the thickness width. The side area of ​​the sheet is much larger than the end area. Therefore, although the conduction of moisture along the fibers is easier than that across the fibers, it is the conduction across the fibers that plays a decisive role in wood drying.
