Water-based dip coating coloring: Generally, it is required to have good sealing properties for wood, good permeability, and uniform coloring, so as to reduce the swelling of wood texture when applying water-based primer and reduce the problem of later collapse of the coating film. The specific construction precautions are as follows:

1. Water-based dip coating coloring: Generally, it is required to have good sealing properties for wood, good permeability, and uniform coloring, so as to reduce the swelling of wood texture when applying water-based primer and reduce the problem of later collapse of the coating film. The specific construction precautions are as follows:

1) The relative humidity of the wood should be detected before construction. The wood moisture content of 12-14% can achieve the best coating effect.

2) Make sure the drain is overflowing with impregnant.

3) The wood should be dusted to avoid contamination of the impregnating agent.

1. The color slurry formulation and production process for the production of laminated color safety glass

2. A special color paste for embroidery

5. Modified acrylate resin emulsion color paste

6. The method of high dispersion pigment printing paste

7. Water-based color paste and method for coating wood products: a water-based color paste and a method for coating wood products, characterized in that the composition (weight) of the water-based color paste is: 0.5-1.5% acid dye, 40-50% Water, 8-12 polyvinyl acetate emulsion or industrial gelatin, 40-50% filler, 0.5-2% pigment.

2. Water-based spray coloring:

Many processes in wood coating require bottom spraying or surface coloring. The construction requirements are relatively simple. Use the spray gun to spray the color directly. It can be sprayed in place according to the effect required by the color plate. According to the different pigment pastes used, it can achieve Different construction effects.

3. Water-based roller coating coloring: The factory assembly line operation often requires roller coating and coloring. The construction substrate is wood with large brown eyes (conduit), and the main purpose is to highlight its texture effect. The specific construction process is as follows:

1) Add 5-20% 71k color paste to the water-based roller coating colorant, and stir well.

2) Pump the colorant with the adjusted color to the roller of the roller coater. After the water-based color paste colorant on the roller is rolled evenly, start to transfer the wood board for coloring. There is a brush roller behind the roller, which will The colorant is squeezed into the tube and the excess colorant is brushed off.

3) After the bottom colorant is dry, spray or roll water-based paint and solvent-based paint as normal on the above-mentioned colored substrate on time.
