    The key points are as follows: (1) weigh deionized water, put it into the reactor, start the high-speed disperser, and control the rotating speed of 400R / min; (2) Weigh dispersant, wetting agent, defoamer, corrosion inhibitor, triethanolamine and deionized water and put them into the batching kettle in turn Continue to stir for 20 minutes at the speed of 400R / min after stirring, put the following raw materials into the batching kettle in turn according to the proportion of the formula: Fe2O3, antirust pigment, mica powder, aluminum tripolyphosphate, talcum and barite Add them in 40min and then accelerate (800r) 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) weigh deionized water, put it into the reactor, then start the high-speed disperser, control the speed of 400R / min; (2) Weigh the dispersant, wetting agent, defoamer, corrosion inhibitor, triethanolamine and deionized water and put them into the batching kettle in turn Continue to stir for 20 minutes at the speed of 400R / min after stirring, put the following raw materials into the batching kettle in turn according to the proportion described in the formula: Fe2O3, antirust pigment Mica powder, aluminum tripolyphosphate, talcum and barite are required to be added for 40min, then accelerated (800r / min) mixing and dispersing for 30min After 30min, adjust the rotation speed to 450R / min, start the feed pump and drive the slurry into the next process; (3) start the feed pump of the grinder, and after the slurry overflows, start the grinder (control the speed of the speed governor 700R / min and the main machine 800r / min) to grind the slurry; during the grinding process, control the temperature below 35 ℃, record the grinding times and the slurry fineness of each grinding, when the slurry fineness is ≤ 45um, stop the grinding, start the feed pump, and put the slurry into the next process; (4) Start the high shear, shear the slurry for 20min (shearing process, control the temperature below 40 ℃), at the same time, start the mixing kettle of the next process, put the alkyd modified styrene acrylic resin into the mixing kettle, and stir it for 20min at the speed of 400-500r / min; (5) put the sheared slurry into the mixing kettle, then slowly add propylene glycol, CS-12, preservative, bactericide, triethanolamine, wt-105a, 113 (control pH below 9 and viscosity within 22-23 seconds) After adding the slurry, continue stirring for 20 minutes, and then put it into the high-level storage tank; (6) filter the filtrate with 220 mesh vibrating screen After the filtrate is put into the semi-finished product, start the mixer every day, mix for 30min (speed 400R / min), and measure the viscosity every day (for 6 consecutive days); (7) put the material and liquid in the reactor into the high-level storage tank, filter with 240 mesh vibrating screen, and measure the viscosity and fineness at the same time (control the fineness below 45um, viscosity for 25 seconds); (8) filling finished products 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,
