Cermet coating powder, sand painting hung hardware appliances (certified), a ceramic coating provided by the Dongguan City, Sha Hong Hardware Appliance Co., Ltd.. Dongguan City, Sha Hong Hardware Appliance Co., Ltd. (www.dgshahong.com) is specialized in the "spray processing, electrical coating, metal spraying, shade spraying, roller coating, ceramic coating" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Sha. Corrosion is the material (in particular a metal material) chemical action occurs under ambient medium, resistant to damage or deterioration of the ability of the process, the corrosion resistance of the coating or electrochemical reaction is caused by physical dissolution of these resist corrosion behavior, material Corrosion testing is mainly carried out laboratory experiments and field experiments coupon types. Commonly used laboratory corrosion test methods (1) thermal spray coatings are mainly atmospheric exposure experiments, liquefied dipping experiment, salt spray test, heat corrosion test, the industrial atmosphere of sulfur dioxide corrosion test, hot corrosion test, and electrochemical testing. Field experiments coupon for the service conditions of the workpiece, select environmental media and the same site conditions such as atmospheric, water, fresh water, soil, various chemical mediators additional coupon accompanying equipment operation, in order to determine their resistance to corrosion. In actual use, the field of corrosion measurement data often takes a long time to conclude, and by strengthening the laboratory test conditions, it can be more accurately reflects the short coat environment and simulate the actual coating corrosion resistance during use, therefore, a large number of production testing is performed laboratory corrosion test. (2) Field coupon and simulation in general is on the basis of laboratory experiments to further test the corrosion behavior of real materials using as much. Evaluation of the corrosion test results, in addition to macroscopic and microscopic observation, but on the uniform corrosion is mainly used to measure the corrosion rate. Corrosion rate is it, the amount of loss in the material per unit area per unit time. 1. Before spraying metal, you need to clean up the place sprayed ceramic coating, can not appear in the painting process impurities phenomenon of thermal spray ceramics, to ensure the integrity of the metal. 2. In the spraying process, just as the metal surface layer of decoration, can not spray paint is too thick, it will cause the paint is too thick color distortion phenomenon occurs, this is not conducive to normal use. 3. When the spray paint to ensure uniformity in need of paint before spraying the metal surface of the ceramic coating stirring, this enables fully fused ceramic paint spraying powder, paint the top does not appear relatively light, following muddy by comparison phenomenon. 4. If paint spraying process is too viscous, then spraying can be used so that the use of additives, but need to be formulated according to the relevant ratio, can not occur imbalance phenomenon. Actually, the most important thing in the spraying process requires attention to ensure sufficiently uniform spray. Can not appear the phenomenon of varying thickness, varying the thickness of the paint, after the spraying will appear to affect the overall aesthetics, resulting in visual disharmony.
