Since the equilibrium moisture content of wood in Shanghai is 14.8%, the floor moisture content used in Shanghai should be controlled at 7% to 14.8%.
process
(1) Natural drying takes about 30 to 40 days to bring the moisture content to about 30%.
(2) Artificial drying takes about 10 to 30 days so that the moisture content is below 10%. This process also distilled the pulp from the wood and balanced the wood cell wall structure. The dry shrinkage performance tended to be stable and consistent.
(3) Health treatment takes about 10 to 20 days. Through this process, the three purposes of wood drying are finally achieved.
Dry equilibrium treatment is so-called heat treatment. The length of this treatment will vary from material to material, but it cannot be artificially shortened. There is a wrong statement in sales that the heat treated floor is "never deformed." In fact, this is impossible. Regardless of how it is handled, the phenomenon of bloated shrinkage that occurs when the moisture content of wood is changed below the saturation point of the fiber is unavoidable.
