    It is suggested that there are many kinds of organic acid and inorganic acid, and their characteristics and properties are different Acid corrosion is a hydrogen evolution electrochemical corrosion The cathodic reaction is 2H + + 2e → H2 The technicians of Zhisheng Weihua anticorrosive coating found that increasing the acidity of the solution will accelerate the cathodic reaction and increase the corrosion rate However, the corrosion rate is also related to hydrogen overpotential, and the oxidation of solution also affects the corrosion of metal The increase of oxidizability usually accelerates the corrosion, but exceeding the limit value can passivate the metal and inhibit the corrosion Most serious corrosion involves inorganic acids, including sulfuric acid, hydrochloric acid and nitric acid Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of coatings news: there are many kinds of organic acid and inorganic acid, and their characteristics and performance are quite different Acid corrosion is a hydrogen evolution electrochemical corrosion The cathodic reaction is 2H + + 2e → H2 The technicians of Zhisheng Weihua anticorrosive coating found that increasing the acidity of the solution will accelerate the cathodic reaction and increase the corrosion rate However, the corrosion rate is also related to hydrogen overpotential, and the oxidation of solution also affects the corrosion of metal The increase of oxidizability usually accelerates the corrosion, but exceeding the limit value can passivate the metal and inhibit the corrosion Most serious corrosion involves inorganic acids, of which sulfuric acid, hydrochloric acid and nitric acid are the most important Acetic acid and formic acid are the main organic acids Inorganic acid, also known as mineral acid, is the general name of acids in inorganic compounds Inorganic acids are generally inorganic compounds that can dissociate hydrogen ions According to the composition, inorganic acids can be divided into oxygenic acid, anaerobic acid, complex acid, mixed acid, super acid concentrated sulfuric acid, dilute sulfuric acid, nitric acid, concentrated hydrochloric acid, chromic acid, phosphoric acid, hydrogen sulfuric acid, dilute hydrochloric acid, hydrofluoric acid, earth acid, ursolic acid, aqua regia and acetic acid Organic acids refer to some organic compounds with acidity The most common organic acid is carboxylic acid, whose acidity comes from carboxyl (- COOH) Sulfonic acid (- SO3H), sulfurous acid (rsooh), sulfur carboxylic acid (rcosh), etc according to the summary of Zhisheng Weihua acid anticorrosive coating personnel, the specific names are aliphatic monobasic, binary, polycarboxylic acids such as tartaric acid, oxalic acid, malic acid, citric acid, ascorbic acid (i.e vitamin C), etc., and aromatic organic acids such as benzoic acid, salicylic acid, malic acid, citric acid, tartaric acid, anti-corrosion Caffelcacid, etc The corrosion mechanism of materials is also different, some are strong acid corrosion, some are weak acid corrosion, some are oxygen acid corrosion, some are hydrogen acid corrosion, and with the increase of temperature, when does the degree of corrosion increase Acid and alkali resistant anti-corrosion coating is a kind of coating which can be applied in relatively harsh environment for a long time and keep a good coating state It is called acid and alkali resistant anti-corrosion coating which is stronger than conventional anti-corrosion coating Beijing Zhisheng Weihua Chemical Co., Ltd., after more than ten years of research and development, has a number of senior anti-corrosion researchers, world-class anti-corrosion coating laboratories in Beijing and Wuhan The developed acid and alkali resistant anti-corrosion coating technology level and anti-corrosion technology extension depth have been leading in China, with a number of core patents In addition, Beijing Zhisheng Boka Energy Saving Technology Research Institute, a material research institute, was established to study energy saving technology, which can be said to be rich in anti-corrosion technology According to the different corrosion principles of different acid and alkali media, Beijing Zhisheng Weihua Chemical Co., Ltd develops different anti-corrosion coatings and selects different anti-corrosion coatings for different corrosion Zs-811 high temperature anticorrosive coating capable of resisting 1800 ℃, zs-1033 anticorrosive coating capable of resisting hydrofluoric acid, zs-822 composite ceramic capable of resisting strong organic solvent corrosion and ultra-high temperature gas corrosion High temperature anti-corrosion coating; zs-1041 anti-corrosion coating that can withstand the strong corrosion and friction of high temperature flue gas and flue gas condensate; zs-711 inorganic anti-corrosion coating that can withstand the corrosion of sea water and sea water moisture; zs-1033 that can withstand the impact of strong friction; zs-821 ceramic anti-corrosion coating that can withstand the corrosion of ether, fluorine and oil; zs-1032 that can withstand the corrosion of nitric acid Materials, Zhisheng Weihua, these kinds of acid and alkali resistant anti-corrosion coatings have been successfully developed with high technology content, wide application prospect and good market prospect Zhisheng Weihua is also an expert in acid and alkali resistant anti-corrosion industry 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,
