The difference between the production process of natural thin wood and artificial thin wood

The products produced from natural thin wood and combined thin wood are all in the range of veneer-decorated wood-based panels, but the methods for producing thin wood and the material requirements are different, and the process of veneer bonding is basically the same.

Natural thin wood is made of real precious wood species by wood cutting or other methods. It requires clear and beautiful wood texture, uniform material and bright color. The structure requires early and late wood, and the wood ray is thick or dense. It can form beautiful wood grain on the cut surface or the string cut surface, and it is easy to cut, glue and finish.

Artificial thin wood, considering that natural thin wood is made of precious wood as a raw material, it is widely used due to the limitation of tree species and resources. Therefore, artificial thin wood has attracted people's attention. It is a decorative veneer made by special processing of common tree species. The tree species used require straight wood texture, uniform material, easy cutting, good gluing properties, and easy dyeing and finishing. The production process is: first, the desired log segment is subjected to rotary cutting to form a thin veneer sheet, and then the cut veneer sheet is bleached and dyed, and then the surface of the veneer is washed with water and dried to a water content. The rate is 8-12%. The dried veneer is laminated to the wood by laminating glue. The commonly used urea-formaldehyde resin glue and polyvinyl acetate emulsion mixed glue. In order to make the artificial thin wood annual ring obvious, a certain amount of pigment can be added to the glue to make the veneer There is a clear line between them, giving people the feeling of distinct annual rings. After the pressure is relieved, the wooden side is planed, and then the radial or chord-shaped veneer is shaved on the flaker. After the thin wood is formed, the artificial film decorative veneer is made by sticking with the substrate.

Chlorophyll Controller

The function of the water quality chlorophyll controller is to monitor and control the concentration of chlorophyll in the water body to maintain the stability and safety of the water quality. It can be connected with a digital Chlorophyll Sensor to continuously monitor the chlorophyll value of water quality. By monitoring the concentration of chlorophyll in the water, the degree of eutrophication of the water body can be assessed, and algae outbreaks in the water body can be detected and warned in time, as well as other pollution sources that may cause eutrophication of the water body. According to the concentration change of chlorophyll, the two relays or 4-20mA current output of the water quality chlorophyll controller can automatically adjust the operating parameters of the water treatment system, such as adjusting the aeration amount, adding chemicals, etc., to maintain the stability and safety of water quality . The water quality chlorophyll analyzer can monitor the chlorophyll concentration in the water body, help the farmers to grasp the water quality, take timely measures to adjust the breeding environment, and prevent the deterioration of the water quality from causing harm to the breeding organisms. It can also be used for the management of lakes, rivers and other waters, to monitor the concentration of chlorophyll in the water, to detect and warn of eutrophication in time, so that corresponding management measures can be taken to protect the health of the water ecosystem.
