Coating technology: production technology of elastic brushed paint

Key tips: 1 Production equipment One set of speed regulating mixing disperser is 500L, with motor power of 7.5kW; one grinder; one bag filter; other commonly used small appliances 2、 Main raw materials Preservative 0.4KG Viscosity thickener water solution 2kg Wetting dispersant Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: 1 One 500L speed regulating mixer and disperser for production equipment, with motor power of 7.5kW; one grinder; one bag filter; other commonly used small appliances Two Main raw material preservative 0.4KG thickening agent thickening agent aqueous solution 2kg wetting dispersant 0.1kg hydroxyethyl cellulose 0.2kg propylene glycol 2kg ethylene glycol 1kg defoamer 0.3KG titanium white pigment 1kg 35kg styrene acrylic emulsion 1kg ammonia water 0.3 thickener water added to 1kg three, production process 1 Dissolve the thickener water solution 1-2 days in advance, and after the dissolution, filter it with 40 mesh screen for standby 2 Prepare color paste or purchase color paste according to the production technology of color paste 3 Take 2 / 3 of the formula water and add it to the pull cylinder of the dispersion mixer, add the wetting dispersant, defoamer and preservative, start the mixer (rotating speed: 300r / min), gradually add the color paste, mix well, add titanium dioxide, and continue to mix for 10min 4 Add the water solution of viscosity and thickening agent, stir it for more than 30min at a high speed (at a speed of over 1000r / min) (in the mixing process, wash the color paste with the remaining water in the formula, empty bucket after the water solution of viscosity and thickening agent is used up, and then return the washing water to the drawing cylinder), so that all materials are fully dispersed, evenly distributed and discharged 5 Discharge the material to the grinder and grind it to below 20 μ M 6 In another mixing cylinder, add propylene glycol and ethylene glycol, and then start the low-speed mixer (200 ~ 300r / min) to make it mix evenly 7 Under low-speed stirring, add the ground slurry, and add the styrene acrylic solution in the formula After low-speed stirring for 30min, make the mixture fully and evenly, slowly add the thickener to adjust the viscosity to 95ku, and slowly add ammonia to adjust the pH to 8 ~ 9 Stop discharging, filtering and filling the finished products after passing the sampling inspection Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
