Coating process: Determination of heat resistance of paint coating

Key tips: test steps for heat resistance of paint coating: 1 Preparation of test panel for determination of heat resistance of paint 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 Dry (or bake and maintain) each painted test plate under the specified conditions for the specified time Before the test, adjust the test plate at the temperature of (23 ± 2) ℃ and the relative temperature of (50 ± 5)% for at least 16h, and conduct the test as soon as possible 2, try Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: paint film heat resistance test steps: 1 Paint film heat resistance test panel preparation: select steel plate, tinplate, aluminum plate, etc required for composite test, and test panel size shall be at least 120mm × 50mm Coating the coating products to be tested according to the specified method Dry (or bake and maintain) each painted test plate under the specified conditions for the specified time Before the test, adjust the test plate at the temperature of (23 ± 2) ℃ and the relative temperature of (50 ± 5)% for at least 16h, and conduct the test as soon as possible 2 Test and measurement: take three test plates and put them into the blast oven or high-temperature furnace with specified temperature If the test is conducted in the oven, the distance between the test plates and each side of the oven shall not be less than 100mm, and the distance between the test plates shall not be less than 20mm If the test is conducted in the high-temperature furnace, try to place the test plates in the middle of the high-temperature furnace, and place the test plates for the specified time under the specified temperature The best way to ensure the uniform heating of the painted test plate is to hang the sample plate with fine wire, or place the test plate on the sample frame made of suitable heat-resistant material or place the coating surface of the sample plate upward on the plate made of heat-resistant material on the support After reaching the specified time, take the test plate out of the oven or high-temperature furnace and cool it to room temperature Check the test plate and compare it with the unheated test plate prepared under the same conditions to see whether the color of the coating film changes or whether there is other damage phenomenon of the coating film At least two test plate phenomena are the same as the experimental results 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,
