Plywood raw material information

Eucalyptus grows fast and can create huge economic benefits. It is a high-quality raw material for the production of paper and wood-based panels. The plywood we produce is a three-layer or multi-layer board material that is made of eucalyptus segments by rotary cutting into eucalyptus veneer or sliced into veneer from eucalyptus wood, and then glued with adhesive. The fiber directions of adjacent layers of veneers are glued perpendicular to each other.

Classification of plywood:

1.One type of plywood is weather-resistant and boiling-water-resistant plywood, which has the advantages of durability, high temperature resistance, and steam treatment.

2.The second type of plywood is water-resistant plywood, which can be dipped in cold water and hot water for a short time.

3.The third type of plywood is moisture-resistant plywood, which can be dipped in cold water for a short time, and is suitable for indoor use at room temperature. For furniture and general construction purposes.

4.The four types of plywood are not moisture-resistant plywood and are used under normal conditions indoors.

It has been suggested that eucalyptus has high economic benefits but also great harm. Large-scale planting leads to barren land, soil fertility decline, land drought, underground rivers and streams dry, and may also cause the degradation and death of native species, which seriously damages the ecology environment.In response to this remark, the Guangxi Forestry Bureau investigated and verified the situation and said, the planting of fast-growing eucalyptus caused the problem of land hardening partly true; the planting of eucalyptus trees affected crops, caused water pollution, and damaged the ecological environment. Eucalyptus plantation has a restoring effect on barren land, and there is no irreversible soil fertility decline phenomenon on rotation forest land.As long as scientific management is done, it is completely avoidable. After scientific demonstration by many experts at home and abroad, so far, there is no evidence that eucalyptus has harmful effects on land, other crops and human health, and no cases of poisoning due to drinking water from eucalyptus forests have been found.

For the planting of eucalyptus, what should be done is to fully understand and standardize, properly plant and develop moderately. As a global tree species, eucalyptus, like all other tree species, also has three major benefits: ecology, economy and society. It also has the functions of water conservation, soil and water conservation, wind and sand fixation, carbon absorption and oxygen production. Whether planting eucalyptus pollutes water sources is currently unknown. The conclusion is that there are many social disputes. The Forestry Bureau of the Autonomous Region has built a fixed ecological monitoring station for continuous monitoring.
