No, specifically as follows:
(1) Calculation of wood moisture content and wood moisture content:
Taking a piece of solid wood of 1M*1M and a thickness of 1CM, the moisture content of solid wood used by general furniture companies is 12% (moisture content is the weight of moisture contained in the wood, and the percentage of the weight of the wood after drying).
(2) Water content of wood after water-based paint:
The theoretical calculation is as follows, according to the solid content of water-based paint 40% (that is, 60% of which is water), artificial spraying amount of 10©O/kg and spraying utilization rate of 40% (the highest), equal to the amount of water sprayed to the wood is 24g/m2, after spraying natural drying process, about 50% of the water will volatilize to the outside, and finally the adsorption of wood to water is about 12g/m2.
(3) Once the wood is closed by the coating film of the first layer, the water sprayed on the second layer cannot enter, unless the first layer of primer is not waterproof.
(4) The actual water absorption on the front surface of the wood is very poor, and the moisture entering the wood is mainly the end, if the end is closed as early as possible during the furniture manufacturing process, the moisture content of the wood is more difficult to change.
