Principle of making insect-proof plywood

The method of making insect-proof plywood is to treat the wood part and the adhesive part of the plywood with insect-proof and ant-proof treatment so as to achieve the overall insect-proof effect of the plywood.

The wood part is treated by immersing the anti-insect liquid into the wood fibers of veneers to eliminate the insects. The parasites in the wood include many types, so the pesticides used should be relatively high in concentration. In order to prevent the secondary generation of parasites from the treated wood, the treatment time should be prolonged accordingly.

The treatment of the adhesive part is to mix insect repellent into the adhesive and press the insect repellent inside the adhesive into the plywood through the pressure of the machine to form an insect repellent layer. This treatment method is relatively fast in terms of time. It only needs to mix with the adhesive, and its effect of insect repellent has been generally recognized by all countries.

In order to improve the anti-insect effect of plywood, we can choose the higher concentration of anti-insect agent to extend the processing cycle as far as possible when time permits. Sometimes the anti-insect agent can not completely penetrate into the inside of wood and need to be soaked twice in the process of soaking. Time is the guarantee. In addition, in the process of binder mixing, we should always pay attention not to mix with other impurities, because as a chemical insecticide, contact with other impurities may reduce its original performance and reduce or lose its insect control effect.
