Solid wood flooring normally uses broad leaf hardwood. Middle and high grade solid
wood flooring mainly use high-quality imported timbers.
Reasonable production procedures are:
1 machine the log into slab,
2 wax the plate end to avoid crack at first,
3 sell to factories and do artificial kiln drying
4 make them into finished flooring.
Artificial kiln drying is the important factor that can ensure the quality of solid wood
flooring. It aims to keep the flooring in form and can not shrink, expand, deform in later
use. Meanwhile, we can also enhance the processability, usability and durability. The key
to the drying quality is that the final moisture content must a little lower than that of the
environmental conditions. 10% to 12% in southern China, 8% to 10% in northern China, 6%
to 8% in northwestern China. We must also ensure that they are completely dry and would
not warp, crack and remove the internal stress.
The drying quality and cost are constrained to each other in usual conditions, but if we
have sound drying equiptments, drying techniques, and operation, we can ensure the
quality and reduce investment and cost at the same time.
As there are many drying approaches and equiptments which have different quality in the
market, we write this paper as reference for hardwood flooring factories to purchase
