: organic acids and inorganic acids are more kinds, characteristics and performance are also very different. Acid corrosion is a kind of electrochemical corrosion of hydrogen analysis, cathode reaction is 2H, 2e→H2. Zhisheng Weihua
anti-corrosion coatings
technicians found that acid corrosion from a thermodynamic point of view, increase the acidity of the solution will accelerate the cathode reaction, improve corrosion rate. However, the corrosion rate is also related to hydrogen per-maye, and the oxidation of the solution also affects the corrosion of metals. Increased oxidation usually accelerates corrosion, but exceeding the limit can blunt the metal and inhibit corrosion. Most severe corrosion involves inorant acids, of which sulphuric acid, hydrochloric acid and nitric acid are the most important. Organic acids are mainly acetic acid and foric acid. Inororal acid, also known as mineral acid, is the general body of acids in inorder compounds. Inororic acids are generally inororal compounds that dissophate hydrogen ions. According to the composition, inorriable acid can be divided into oxygenated acid, anaerobic acid, compound acid, mixed acid, super-acid sulphuric acid, thin sulfuric acid, nitric acid, thick hydrochloric acid, chromic acid, phosphoric acid, hydrosulphate, thin hydrochloric acid, soil acid, usuric acid, wang shui, acetic acid.
acid refers to some acidic organic compounds, the most common organic acid is pyric acid, the acidity of which is derived from the carboxyl (-COOH). Sulphuric acid (-SO3H), sulfonate (RSOOH), sulfuric acid (RCOSH), etc., Chissa Weihua acid corrosion anti-corrosion

personnel concluded that the specific name is the fat family of one, two, polycarbonate such as taurine Acids, herbal acids, macarates, asbic acids, astroceric acids (i.e. vitamin C) and so on, there are aromatic organic acids such as benzoic acid, salginic acid, maic acid, lyphosate, talc acid, asybic acid coffee acid (Caffelcacid) and so on.
the corrosion of materials is also different, some strong acid corrosion, some weak acid corrosion, some oxygenated acid corrosion, some hydrogenic acid corrosion, and these acids with the temperature increase, the degree of corrosion geometric growth and strength. Acid-alkali anti-corrosion coating is a coating that can be used in relatively harsh corrosion environment for a long time and maintains a good coating state, which is stronger than conventional anti-corrosion coatings and is called acid-alkali anti-corrosion. Beijing Zhisheng Weihua Chemical Co., Ltd., after more than ten years of research and development, more than senior anti-corrosion researchers, in Beijing and Wuhan have a world-class anti-corrosion coating laboratory, the development of acid-alkali anti-corrosion coating technology level and anti-corrosion technology continued depth has been in the forefront of the domestic, with a number of core patents. But also targeted the establishment of the Materials Research Institute - Beijing Zhisheng Boca Energy Saving Technology Research Institute, specializing in research and development of energy-saving technology, can be said to be strong anti-corrosion research and development technology.
according to different acid-base media corrosion principle, Beijing Zhisheng Weihua Chemical Co., Ltd. developed different anti-corrosion coatings, for different corrosion selection of different anti-corrosion coatings. Resistant to high temperature corrosion of ZS-811 high temperature anti-corrosion coatings at 1800 degrees C, HS-1033 corrosion-resistant coatings resistant to hydrofluoric acid, corrosion of strong organic solvents and ultra-high temperature gases Corrosive ZS-822 composite ceramic high temperature anti-corrosion coating, ZS-1041 anti-corrosion coating that can withstand the strong corrosion friction of high temperature flue gas and flue gas condensate, ZS-1041 flue gas anti-corrosion coating that can withstand seawater and sea water moisture corrosion S-711 inorgable anti-corrosion coatings, corrosion-resistant ZS-1033 under the impact of strong friction, ZS-821 ceramic anti-corrosion coatings that can withstand erosion and corrosion of ethers, fluorines, oils, etc., and nitric acid Corrosion of ZS-1032 anti-oxidation anti-corrosion coatings, Zhisheng Weihua these various acid-alkali anti-corrosion coatings research and development success, high scientific and technological content, wide application prospects, market prospects, Zhisheng Weihua also anti-acid and alkali anti-corrosion experts.
