Coating process: water boiling test of coating

Core tips: 1 Preparation of water-resistant boiling test plate for coating: Steel plate, tinplate, aluminum plate, etc are required for composite test, and the size of test plate shall be at least 120mm × 50mm Coating the coating products to be tested according to the specified method, drying or curing 2 Test steps for water boiling resistance of coating: Place the sample in boiling water, keep for 15 minutes, take out and dry ① Observe whether the coating has abnormal phenomena such as blistering and falling off; ② Absorb a small amount of pure water with a rubber head dropper, and directly drop it on the coating, and visually observe whether the water droplet diffuses; According to ②, it can be judged whether the coating is fully cured 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 Coating home news: 1 Preparation of water-resistant boiling test plate for coating: steel plate, tinplate, aluminum plate, etc required for composite test shall be selected, and the size of test plate shall be at least 120mm × 50mm Coating the coating products to be tested according to the specified method, drying or curing 2 Water boil test procedure of coating: put the sample piece in boiling water, keep it for 15 minutes, take it out and dry it ① Observe whether the coating has abnormal phenomena such as blistering and falling off; ② draw a small amount of pure water with a rubber head dropper, directly drop it on the coating, and visually observe whether the water drop diffuses; according to ②, judge whether the coating is fully cured, such as the bottom and surface are not fully cured, the water affinity may be lost after boiling, and the water drop does not diffuse 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,
