Selection of diatom mud: anti oxidation coating

Core tip: overview of anti-oxidation coating: the anti-oxidation coating is composed of ultra-fine inorganic metal oxide and Zhisheng Weihua high temperature solution The temperature resistance can reach 1700 ℃, the coating is completely transparent, and there is no smell at room temperature and high temperature After painting, the coating does not affect the original color of the object, and can form an interpenetrating network structure with the surface of the inorganic material object, with good adhesion It has the functions of heat insulation, anti-oxidation and anti-corrosion, prolongs the service life of the matrix, ensures that the matrix does not rust under high temperature, and saves energy and environmental protection The working mechanism of anti-oxidation coating: 1 They are insoluble in water and not easy to be broken down by corrosive medium 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 Coating home news: anti oxidation coating overview: the anti-oxidation coating is composed of ultra-fine inorganic metal oxide and Zhisheng Weihua high temperature solution The temperature resistance can reach 1700 ℃, the coating is completely transparent, and there is no smell at room temperature and high temperature After coating, the coating is coated It does not affect the original color of the object, can form an interpenetrating network structure with the surface of the inorganic material object, has good adhesion, has a certain degree of heat insulation, anti-oxidation, anti-corrosion protection, prolongs the service life of the matrix, ensures that the matrix does not rust at high temperature, energy conservation and environmental protection The working mechanism of anti-oxidation coatings: 1 They are inert pigments and fillers with stable chemical properties, which are insoluble in water and not easy to be destroyed by decomposition of corrosive medium The coating itself is relatively stable; The particles of these pigments and fillers have good filling effect and less surface defects, making the structure of the coating very dense Not only the strength is increased, but also some pigments and fillers can reduce the penetration speed of water, oxygen and ions to the paint film when they are used properly 2 Some anti-oxidation coatings are mainly made of fine scaly materials These scales are arranged in parallel with the substrate in the paint film, overlapping and overlapping each other, which can prevent the contact between the corrosive medium and the substrate, or extend the penetration path of the corrosive medium to the substrate, so as to achieve the effect of corrosion inhibition The advantages of anti-oxidation coating are as follows: 1 The coating has certain thermal insulation property After coating at 1200 ℃, it can be insulated at 110 ℃, after coating at 500 ℃, it can be insulated at 40 ℃, and after coating at 200 ℃, it can be insulated at 15 ℃; 2 The coating has a certain degree of anti-oxidation, metal objects are very easy to be oxidized in the high temperature environment, and the oxidation rate of the metal at high temperature will be reduced by more than 30% after coating; 3 The coating has a certain degree of anti-corrosion, brushing on the surface of the object, on the basis of not affecting the surface color of the object, it has a good physical and electrochemical anti-corrosion effect, reducing object corrosion; 4 Improve the temperature resistance of the object, brush the paint on the combustible object, greatly improve the ignition point of the object, prevent the object from burning, brush on the metal object, can improve the temperature resistance and oxidation resistance of the metal; 5, easy to use, brush on the surface of the inorganic object by spraying, brushing, dipping and other methods, brush evenly; 6 The coating has good adhesion and is not easy to peel and fall off; 7 Colorless, the coating is used at room temperature and high temperature, without color change, with definite transparency; 8 It has strong thermal deformation resistance, good elasticity, and will not crack or fall off at high / low temperature; 9 Hazard: the paint does not have any peculiar smell, does not contain or produce harmful VOC components, carcinogens and other harmful polymers, decomposition products and by-products; 10 Stability, stable chemical performance of the paint, no chemical reaction with any substance, and is not affected by acid, alkali and corrosive substances Home of coatings focuses on the news and information of coatings, diatom mud, paint coatings, coating process, fire retardant coatings and coatings, paint coatings, coating process, decoration knowledge and decoration effect map of fire retardant coatings,
