Corrosion refers to the physical and chemical interaction between metals and the environment, which causes changes in metal properties, resulting in damage to metals, the environment and their composition. Anti-corrosion coating engineers said that corrosion is a chemical change, corrosion is divided into many cases, such as sulfuric acid will be corroded in the object of H, O to 2:1 ratio out, because H2O molecules in the ratio of H, O is also 2:1, so sulfuric acid corrosion is also called Dehydration, such as NaOH corrosion, it will destroy the protein of the corroded object, from which the corrosion effect of acid-base corrosion refers to the acid refers to the ionization of the cations produced by all hydrogen ions are hydrogen ion compounds;
acid is corrosive, the solution is acidic, can react with lively metal, alkali is also corrosive, the solution is alkaline, resistant to acid-base corrosion, protect the substrate from oxidation and rust, acid-base anti-corrosion coatings for heavy corrosion workers Brushing under the conditions, for different anti-corrosion environmental conditions supporting the development of technical indicators, such as chemical-resistant media, salt-resistant water, salt-resistant fog, moisture-resistant heat, oil-resistant, mold-resistant, atmospheric aging, alkali-resistant, potassium-resistant, brine corrosion and so on. After many years of research and development of ZS-1034 acid-base anti-corrosion coating, ZS-1034 acid-alkali anti-corrosion coating with high coating tightness, can effectively shield gas and corrosion fluid penetration, very good to prevent the accumulation of static heat coating, high conductivity, effectively prevent acid-base corrosion media physical reactions and chemical reactions, coating hardness, shock resistance, smooth satiety, high coefficient of heat shock, high adhesion and so on.
acid-base corrosion resistance, suitable for long-term corrosion and corrosion resistance in acid-base solutions, after long-term research and development of heavy anti-corrosion tests, ZS-1034 acid-alkali anti-corrosion coatings are applicable to a wide range of suitable brushes in part of the concentration of various acid-alkali gas liquid, solvents, intermediates and salts corrosion-resistant, long-term protection of the body from corrosion. ZS-1034 acid-base anti-corrosion coatings can withstand dynamic acid-base value changes, cross-denaturation resistance to acid, alkali or solvent corrosion resistance, resistance to different corrosion media alternating good, that is, acid-base, solvent in a short period of time to change acid-base media ZS-1034 acid-alkali antiseptic coating PH value alternating changes in corrosion protection, different corrosion media alternating changes, strong corrosion resistance, anti-aging, with the base material matching the temperature-line expansion coefficient is high, high adhesion capacity.
acid-base corrosion refers to the physical and chemical interaction between metal and environment, which makes the metal performance change, resulting in damage to metal, environment and its composition, and the type of acid-base corrosion can be divided into wet corrosion and dry corrosion. Acid-alkali wet corrosion refers to the corrosion of metals in the presence of water, while acid-alkali dry corrosion refers to corrosion in dry gases without liquid water. Because the atmosphere generally contains water, chemical production also often deal with a variety of water solutions, so wet corrosion is the most common, but high temperature operation caused by dry corrosion hazards can not be ignored. Weak acids and alkalis generally do not react with metals, so it can be said that they are not corrosive.
