What is wood dyeing technology?
The dyeing effect of wood is measured by the above indexes such as dyeing rate, dyeing property and light fastness. In addition to the influence of pH value and dyeing process of dyes, adjuvants and dyes, the wood structure, Chemical composition of the impact. Due to the diversity and complexity of the wood structure, coupled with the wood dyeing industry is a new industry, so different tree dyes, different dyes on the wood dyeing, different products for the necessary dyes there are many problems, further research.
There are a variety of wood dyeing methods, depending on the use of coloring material may be. Wood industry is usually used in veneer dyeing, veneer dyeing and solid wood dyeing and other methods. Thin wood dyeing refers to the thickness of 0.1 ~ 0.3mm sliced veneer. Veneer dyeing is the use of immersion treatment on the peeling veneer uniform dyeing method, veneer thickness of 0.5 ~ 3mm. Veneer dyeing process due to different differences between tree species and dyes. Dyed veneer is mainly used as a wood blank. Solid wood dyeing is the opposite material or logs for dyeing, dyeing materials are mainly used for slicing veneer, or the production of high-grade furniture or decorative materials. Due to the large thickness and long wood, it is difficult to stain the wood evenly through the self-permeability of the dyeing liquid under the conventional conditions. It must be completed under complex conditions such as high temperature, vacuum and high pressure.
Wood dyeing is a combination of dyes and wood chemical or physical chemistry, so that the wood has a certain color of the processing process is to improve the quality of wood surface, improve the visual characteristics of wood and increase the value of wood an important means. Wood dyeing by dye dyeing, chemical coloring and pigment coating. Wood dyeing is an important part of wood processing and utilization. Wood dyeing according to the solvent is divided into water-soluble dye dyeing, alcohol-soluble dye dyeing and oil-soluble dye dyeing, according to the dyeing method is divided into deep staining and surface staining. Deep dyeing is mainly used for processing veneer and wood, such as veneer veneer dyeing and technical wood veneer dyeing. Surface dyeing is the use of spraying, brushing or leaching method to deal with the surface of wood products.
These professional wood knowledge terminology, you can go to the fish beads, China Wood website, wood city network and other professional website to view the wood knowledge and technical section, should be able to find to.
