Coating process: coating sagging test

Core tip: the flow test instrument is often used to detect the flow of paint The specific determination method is as follows: （1） Put the base of the tester on a platform, and then put the test plate on the appropriate position of the base Place the scraping coating on the top of the test plate surface, with the scale facing the operator (2) Mix the sample well and place a sufficient amount of sample in the opening in front of the scraper Hold both ends of the scraper with both hands, make one end of the scraper keep close contact with the island edge all the time, and scrape and pull from top to bottom steadily and continuously, and keep straight at the same time Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Coating home news: coating color paint sagging detection is often carried out by sagging tester The specific measurement method is as follows: (1) place the base of the tester on a platform, and then place the test plate on the appropriate position of the base Place the scraping coating on the top of the test plate surface, with the scale facing the operator (2) Mix the sample well and place a sufficient amount of sample in the opening in front of the scraper Hold both ends of the scraper with both hands, make one end of the scraper keep close contact with the island edge all the time, scrape and pull from top to bottom steadily and continuously, and keep straight without fluctuation at the same time The operation was completed in about 2-3s (3) The test plate with the film scraped shall be placed vertically immediately The strip film shall be placed in a transverse direction and kept "thin at the top and thick at the bottom" (4) After the coating surface is dry, observe the sagging If the thickness of the film does not flow to the next thickness of the film, that is, the thickness of the film does not flow, as shown in the figure below, the area within 20 mm at both ends of the film is not counted Fig 1 no sagging sketch Fig 1-5 film is no sagging, and the thickness of the 5th wet film is no sagging degree The same sample is tested in parallel with three samples The test results shall be expressed as the maximum wet film thickness without sagging measured by no less than two samples (in microns) 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,
