Coating process: Test Method for salt spray resistance of Waterborne Coatings

Core tip: salt spray resistance test of water-based coating is one of the important test items to inspect the corrosion protection, rust prevention and yellowing resistance of products in complex and humid environment The following is an introduction to the whole process of salt spray resistance test: 1 Test environment and equipment: Salt spray test box, absorbent paper, distilled water 2 Test process: 1》 Clean the product and place it in the salt spray test chamber at an angle of 30-45 degrees 2 Set the spray time The temperature inside the control box is stable at 35-- 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 Home of coatings: salt spray resistance test of water-based coatings is one of the important test items to test the corrosion resistance, rust prevention and yellowing resistance of products in complex and humid environment The following is an introduction to the whole process of salt spray resistance test: 1 Test environment and equipment: salt spray test box, absorbent paper, distilled water 2 Test process: 1》 Clean the product and place it in the salt spray test chamber at an angle of 30-45 degrees 2, set the spray time The temperature in the control box is stable at 35--47 degrees, the humidity is 95%, the pH value of the solution is 6.5--7.2, the pressure barrel pressure is 1MPa 3 Continuous spray 5% of the salt water is observed every 8 hours 4》 At the end of 4000H test, take out the object and place it for 24h for normal temperature drying, and conduct appearance inspection 3 Judgment standard of test results: 1 After 4000H salt spray test, the surface of the paint film of the object has no peeling, rust, peeling and other phenomena, no obvious defects, and no obvious decrease in adhesion 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,
