Coating classification: alkali resistance of coating

Core tip: the alkali resistance of paint refers to the resistance of paint film to alkali corrosion The specific inspection method in the national standard is: first, prepare the test board on the standard size asbestos cement board according to the standard provisions, and seal the prepared test board with 1:1 paraffin and rosin mixture for back sealing Then immerse 2 / 3 of the test plate area into the saturated solution of calcium hydroxide at 23 ± 2 ℃ until the specified time Observe whether there are blistering, crack, peeling, pulverization, softening and dissolution of the coating The alkali resistance of the coating is different from what we often call back alkali 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 Home of paint news: the alkali resistance of paint refers to the resistance of paint film to alkali corrosion The specific inspection method in the national standard is: first, prepare the test board on the standard size asbestos cement board according to the standard provisions, and seal the prepared test board with 1:1 paraffin and rosin mixture for back sealing Then immerse 2 / 3 of the test plate area into the saturated solution of calcium hydroxide at 23 ± 2 ℃ until the specified time Observe whether there are blistering, crack, peeling, pulverization, softening and dissolution of the coating The alkali resistance of coatings is different from what we often call alkali return The alkali resistance of coatings tends to investigate whether the paint film of products is damaged under the alkaline condition, while alkali return refers to the precipitation of alkaline substances on the basic substrate of the paint film, and the paint film is generally not damaged 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,
