Water-based ink process

High-grade water-based ink manufacturing process 1. According to the formula, acrylic resin liquid, ethanol and partially deionized water are put into a dispersion tank, and the mixture is fully stirred and dispersed.
2. The formulation shall be quasi-pigmented, dispersant, and 0.3 parts defoamer put into the dispersion tank, fully dispersed and mixed.
3. Disperse the material and move it to the sand mill for grinding. Grind 3-4 tracks. Measure the fineness to 25um or less. Otherwise, continue to grind until the fineness reaches the requirement.
4. Move the ground material into the dispersion tank, and in turn press the formula, which is called Q831, Q817, water-based wax, ethylene glycol butyl ether, 0.5 parts of defoaming and deionized water into the dispersion tank. After that. (Disperser speed is controlled at around 300 rpm)
Medium-range water-based ink manufacturing process 1, according to the required standard resin solution, part of the deionized water, into the dispersion tank, fully stirred and dispersed.
2. According to the formula, the required standard pigments, dispersants, and 0.3 parts of defoamer are thrown into the dispersion tank, and are fully dispersed and uniformly mixed.
3. Move the dispersed material to the sand mill, grind 3-4 tracks, and measure the fineness to 25um or less, otherwise continue grinding until the fineness meets the requirement.
4. The ground material is weighed into a dispersion vessel, which is in turn quasi-Q817, Q831, water-based wax, ethanol, ethylene glycol butyl ether, 0.5 parts defoamer, and deionized water into a dispersion vessel according to the requirements of the distribution. It can be dispersed evenly. (Disperser speed is controlled at around 300 rpm)
General aqueous ink manufacturing process
1. According to the formula, the A-2175 resin solution, pigment and emulsified oil shall be quasi-adjusted and put into the dispersion tank, and be fully stirred and dispersed.
2. Distribute the dispersed material to the sand mill for grinding. Grind the 3-4 tracks and measure the fineness to 25um or less. Otherwise, continue to grind until the fineness reaches the requirement.
3. Move the ground material into the dispersion tank, and then turn it into the dispersion tank according to the formula, which is called quasi-methanol (or ethanol), ethylene glycol butyl ether, deionized water, and antifoaming agent. can.
Production Process Precautions and Quality Control a) Before starting operation, first check whether the production equipment is clean and normal operation.
b) The production workshop must be far away from the fire source, and the cooling and ventilation, the sealing of the sander, and the cooling are in good condition.
c) The amount of raw materials needed to be weighed strictly according to the recipe.
d) Operate in strict accordance with the order of feeding.
e) After various raw materials are introduced into the plant, small batches of laboratory production should be conducted first to ensure the quality of industrial products.
