Coating knowledge: establishment of different acid-base corrosion protection systems for heavy-duty coatings

Core tip: heavy duty anticorrosive coating refers to a kind of anticorrosive coating that can be applied in relatively harsh corrosion environment and has a longer protection period than conventional anticorrosive coating Fields of application include petrochemical industry, mine smelting, energy including natural gas, oil, coal transportation and storage, transportation, and marine engineering, such as oil drilling platform, coastal facilities, etc At present, the commonly used heavy-duty anticorrosive coatings are epoxy resin coating, polyurethane resin coating, glass flake coating, etc However, due to the problems of poor weather resistance, low mechanical strength and low temperature resistance, the modified heavy-duty anticorrosive coating came out Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Home of coatings: heavy duty anticorrosive coating refers to a kind of anticorrosive coating that can be applied in relatively harsh corrosion environment and has a longer protection period than conventional anticorrosive coating Fields of application include petrochemical industry, mine smelting, energy including natural gas, oil, coal transportation and storage, transportation, and marine engineering, such as oil drilling platform, coastal facilities, etc At present, the commonly used heavy-duty anticorrosive coatings are epoxy resin coating, polyurethane resin coating, glass flake coating, etc However, due to the problems of poor weather resistance, low mechanical strength and low temperature resistance, the modified heavy-duty anticorrosive coating came out Beijing Zhisheng Weihua Chemical Co., Ltd is a large-scale enterprise dedicated to the R & D and production of industrial heavy-duty anticorrosive coatings Now it has formed a relatively complete ZS series heavy-duty anticorrosive coating system, which can basically meet the needs of heavy-duty anticorrosive coatings in various industries Establishment of different acid-base corrosion protection systems for heavy-duty coatings Zs-711 marine zinc rich anticorrosive coating is a new type of inorganic polymer coating, which is composed of new inorganic polymer, dispersed activated metal, metal oxide nano material and rare earth ultra-fine powder It can react with atoms on the surface of the object rapidly to form an inorganic polymer anticorrosive coating with physical and chemical double protective effects It can be applied to the surface of the object through chemical bond Environmental pollution-free, long service life, anti-corrosion performance up to the international advanced level, is in line with the environmental requirements of high-tech replacement products Zs-811 high temperature and anti-corrosion functional coating - the temperature resistance can reach 1800 ℃, the functional coating can protect the matrix in the environment of high temperature gas (smoke), fire, high temperature liquid (sea water, sewage), anti-corrosion, anti-oxidation, sealing protection, etc., Zhisheng functional coating has high stability and wear resistance, will react with other active molecules in high temperature environment, and has long service life Zs-822 composite ceramic anticorrosive coating, high temperature resistant silicon fluoride solution, can reach 1400 ℃ The main components of the pigment are yttrium rare earth powder, composite α - ceramic powder, silicon carbide and so on The coating has high temperature resistance, forming dense ceramic glaze under high temperature, with hardness up to 7h, smooth and self-cleaning coating, impact resistance, long-term acid and alkali resistance, strong adhesion, water and oil resistance, as well as resistance to organic solvent corrosion Zs-1032, a heavy-duty anti-corrosive coating, can withstand the oxidation corrosion of strong oxidizing materials such as concentrated acid solution (salt, sulfur, nitrate), strong intermediate and polar solvent for a long time, as well as the penetration corrosion of aviation kerosene and other oil The swelling rate of zs-1032 strong oxidation-resistant coating is less than 5% in non-polar solvent, gasoline, jet fuel oil, HNO3, sulfuric acid, butyl acetate, xylene, butanone, and absolute ethanol high polar solution after immersion at 100 ℃ for 500 hours Zs-1023 super high temperature metal anti-oxidation coating has a long-term ultra-high temperature resistance of 3000 ℃, which can well protect the metal from oxidation and corrosion under high temperature The ultra-high temperature anti-oxidation coating can effectively prevent oxygen from penetrating into the matrix under high temperature, with high hardness, impact resistance, high linear expansion coefficient and good thermal vibration coefficient Zs-1031 wear-resistant and corrosion-resistant coating: inorganic organic interpenetrating network polymer is used as the film-forming solution, pure inorganic ceramic filler, the temperature resistance of the coating can reach 600 ℃, when the coating is cured, the solution and filler are crosslinked tightly, the glass phase is stable, the acid and alkali resistance are good, the hardness of the coating is high, the impact and erosion resistance are resistant, the adhesion is strong, and both wear-resistant and corrosion-resistant effects are taken into account Zs-1041 smoke anti-corrosion coating is made of interpenetrating network polymer mainly composed of inorganic polymer as film-forming material The main components are nano bead, ceramic bead, silicon carbide, boron nitride, fine-grained aluminum oxide, ultra-fine zinc oxide, titanium oxide, etc the gold ceramic functional filler is made to improve the wear resistance and anti-corrosion performance of the coating Inorganic fiber is used to enhance the impact resistance of the coating Striking performance Temperature resistance range: the internal and external surfaces of flue, chimney, dust remover, kiln, boiler, etc are anticorrosive, and the service temperature is less than 750 ℃ The physical principle of anti-corrosion is to separate the protected materials from the corrosive substances The physical principle of antirust coating is to use film-forming agent to obtain dense anti-corrosion coating to isolate the damage of anti-corrosion effect on the protected materials The electrochemical effect of anti-corrosion refers to adding some special substances to the antirust coating, so that when water and oxygen pass through the antirust coating, they will react to form anti-corrosion ions, making the surface of steel and other metals passivated, so as to prevent metal from being damaged The dissolution of ions can achieve the purpose of heavy corrosion protection [focus on WeChat official account "paint net"; pay attention to surprises, scan code to see if your husband is selling paint..
