The working capacity of the heat pump dryer is related to the environment in which it is used. After one year of continuous use, the interior of the heat pump dryer unit may become dirty and the working capacity will decrease. Therefore, special equipment inspection and equipment maintenance must be carried out. For this kind of inspection and maintenance work, it is recommended that you contact the heat pump dryer manufacturer or its maintenance department. Users should pay attention when using and maintaining this unit: all safety protection devices in the unit are set before leaving the factory, and do not adjust it by yourself. .

1. Preheating treatment: First, the control system only opens the steam injection valve, and preheats by steam injection through the evaporation water tank in the kiln. The dry bulb temperature (Td) and the wet bulb temperature (Tw) in the kiln rise synchronously. The rapid 3-hour steam injection makes the drying medium in the kiln reach Td = Tw = 9 0 ℃ or more. Then, depending on the thickness of the dry sheet, keep it for different times to preheat the sheet.

Thermal modification of wood: heating the wood, resulting in a certain degree of degradation of the wood components, resulting in the desired improvement of the wood properties

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.

On May 11th, the workshop of the factory was very busy. The order from the old customer in Malaysia was being loaded methodically. Thank you for the trust of the old customer.

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.
