The excellent economic performance of water-based inorgable steel structure anti-corrosion coatings is of great significance

China Coatings Network
: Steel structure engineering is based on steel production structure, is one of the main types of modern building structure. Global steel production exceeds 1 billion tons per year, and it is estimated that about 30 per cent of annual output is due to corrosion, of which about one-third is permanently lost due to non-recyclability, resulting in economic losses of up to trillions of dollars. In addition to a large number of steel structures outdoors to suffer from atmospheric corrosion, metal equipment in coastal areas and chemical production by acids, alkalis, salts and other corrosive media erosion is particularly serious. This not only requires a lot of financial and human resources for perennary corrosion protection, but also has potential safety risks.
As far as the current stock of science and technology is concerned, it is unrealistic to start from the steel structure itself to solve the corrosion problem, the general cost of stainless steel is expensive, the price is several times to ten times the specifications of ordinary high-quality steel, and the service life is limited. Other corrosion-resistant materials are mainly not strong enough, limited service life, poor economy and a series of problems, and the use of
coatings
coating to prevent metal corrosion is the most widely used, the most effective and most economical means. It is also due to the pollution of the atmosphere by organic volatiles (VOCs) in solvent-based coatings. Therefore, the development of long service life, low price, safety and non-toxic, energy conservation and environmental protection, construction convenience, a wide range of applications of new water-based steel
corrosive coatings
is very necessary. Moreover, this research is beneficial to the development of green economy and circular economy, and meets the requirements of sustainable development.
corrosion of steel structure in the environment is inevitable, especially rust, under the action of aggressive medium, steel will produce corrosion, aggressive medium mainly acid corrosion, alkali corrosion and salt corrosion three types. According to its morphological division, there are two categories: liquid phase corrosion and gas phase corrosion. In addition, atmospheric humidity and rain, atmospheric dust, temperature and steel contact with other metals will cause corrosion of steel. Located in Fengtai District East Railway Camp, Beijing Zhisheng Weihua production and research and development of material corrosion 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 rise, corrosion degree geometric growth and strength. The material ZS-711 inororated anti-corrosion coatings, ZS-811 high temperature anti-corrosion coatings and ZS-1033 anti-corrosion coatings for different projects in accordance with the national standard test, test results above the corrosion of corrosion-resistant coatings corrosion of corrosion-resistant acids fully meet international design standards. Acid-resistant corrosion anti-corrosion coating solution is a synthetic membrane solution of inorganic polymer specially made by the new Chissa Weihua, which has been based on si-O-Si-key, grafted organic alkyl side chain as a supplement, and then hydroxylated as an anti-corrosion film of end chain chelation. ZS-711 anti-corrosion coating molecular bonds on silicon atoms connected to the chelated hydroxyl, alkyl has a very good anti-corrosion triple synergy effect, solution stability is strong, reduce the impact on the polymer interior, film is denser, strong adhesion, high temperature resistance. The above acid-resistant anti-corrosion coating can effectively prevent uniform corrosion, uneven corrosion, point (pit) corrosion, stress corrosion, hydrogen brittleness and other metal corrosion phenomena in the workshop steel frame structure, and completely solve the stress corrosion and hydrogen brittleness of the steel frame structure in the workshop are suddenly brittle fracture without obvious signs of deformation, to avoid dangerous occurrence, to ensure the safety of industrial production.
Zhisheng Weihua ZS-711 inorganic anti-corrosion paint is a highly dispersed and active passivated metal particles, nano graphite scales, nanometal sex oxides, ultra-fine rare earth ultra-micro-powder and other components. Zhisheng Weihua inorance anti-corrosion coatings after the biochemical pigments, in anti-corrosion is able to play the role of corrosion-reinforced polarization, high acid resistance to alkali corrosion resistance, play a good role in neutralizing and preventing the substrate level rise, but also to avoid the presence of coating pinholes, coating hardness, wear-resistant impact, acid-base aging time. Now this new inormeric polymer anti-corrosion coating has become the most common and important coating to protect steel. ZS-711 inorgeable polymer anti-corrosion coatings in the atmosphere, underground, ocean, petroleum liquids, chemical materials, sewage, transportation in the important field of anti-corrosion applications are almost no comparable products to replace.
