Solid wood dyeing is a method of dyeing sheets or squares. Dyed materials are mainly used to make sliced ​​thin wood or to produce high-grade furniture and decorative materials. Due to the large thickness and long wood, it is difficult to uniformly dye the wood under the conventional conditions by the self-permeability of the dyeing liquid, so it needs to be completed under complicated conditions such as high temperature, vacuum and high pressure. This is a wood uniform dyeing vacuum pressure treatment process.
(1) Formulated acid dye 1%
Penetrant 0.05%
NaCl 1%
pH = 4.5.
(2) Dyeing process
Wood→Adding dyeing liquid→Reduced pressure→Normal pressure treatment→Pressure pressure holding→Discharge dyeing liquid→Unloading→Drying instructions:
1. Wood: Wood should be dried to a moisture content of 15%.
2. Decompression: Exclude air and excess water in the wood. The decompression time at 30 °C is 8 to 10 hours for softwood and 12h for hardwood.
3. Atmospheric pressure treatment: the processing time of softwood is 8~10h, and the time of hardwood is 12h.
4. Pressurized pressure: The softwood is kept at a pressure of 20kg/cm2 for 6h, and the hardwood at a pressure of 30kg/cm2 for 8h.
5. Dyeing waste liquid: Excluding excess dyeing liquid adhered to wood, saving cost and reducing pollution to subsequent sections.
6. Drying: It should not be dried by hot air. Vacuum drying and dehumidifying drying methods should be used.
