Coating technology: Determination of fineness of paint

Core tip: fineness of paint: the size or dispersion uniformity of particles such as paint or paint paste inner color (filler), expressed in μ M The paint shall be stirred evenly before the test, and then the fineness meter shall be wiped clean with a soft wiping cloth dipped in an appropriate amount of solvent Use a glass rod to take 2-3 drops of the paint to be tested and put them on the upper part of the groove of the fineness meter Take a scraper with your right hand and quickly scrape the paint from top to bottom (the scraper and the fineness meter plane are 90 ° during the scraping process) Observe the position where the particles appear in the paint If the particles begin to appear below a certain position, this place 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 Home of paint news: fineness of paint: the size or uniformity of particles such as color paint or paint paste inner color (filler), expressed in μ M The paint shall be stirred evenly before the test, and then the fineness meter shall be wiped clean with a soft wiping cloth dipped in an appropriate amount of solvent Use a glass rod to take 2-3 drops of the paint to be tested and put them on the upper part of the groove of the fineness meter Take a scraper with your right hand and quickly scrape the paint from top to bottom (the scraper and the plane of the fineness meter are 90 ° in the process of scraping) Observe the position where the particles appear in the paint If the particles begin to appear below a certain position, the corresponding value in this place is the fineness of the paint to be tested The test is conducted three times, and the arithmetic mean value of three adjacent readings is taken as the test result Paint house focuses on the news and information of coating, diatom mud, paint coating, coating process, fire retardant coating and coating, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fire retardant coating,
