Coating technology: testing technology of water-based colorful paint

Core tip: JIS The technical requirements of k5667 standard (interior wall) project are uniform after mixing in the container, no caking, construction spraying or brush coating, no blocking drying time (H), surface drying time ≤ 1 hour, the appearance of paint film is not different from the sample in color, pattern and covering, and the difference in liquidity is not less than the sample's alkali resistance, no abnormal scrubbing resistance after immersion in calcium hydroxide solution for 18 hours, 100 times of solid content Amount ≥ 20% adhesion 100 water resistance (96h) no shedding, blistering, wrinkle and peeling powder alkali resistance (48h) no shedding, blistering, wrinkle and peeling powder scrub resistance 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: the technical requirements of JIS k5667 standard (interior wall) project are uniform after mixing in the container, no caking, construction spraying or brushing, no blocking, drying time (H), surface drying time ≤ 1 hour, the appearance of paint film is not different from the sample in color, pattern and covering, and the difference in fluidity is not less than the alkali resistance of the sample Immersion in calcium hydroxide solution for 18h, no abnormal scrubbing resistance, 100 times solid content ≥ 20%, adhesion, 100 times water resistance (96h), no peeling, blistering, wrinkle skin and powder peeling, alkali resistance (48h), no peeling, blistering, wrinkle skin and powder peeling, scrub resistance ≥ 1000 times, the home of coatings focuses on coatings, diatom mud, paint coating, coating technology, news and coating of fire retardant coating, diatom mud, Paint coating, coating process, decoration knowledge and decoration effect drawing of fire retardant coating,
