    According to the corrosion mechanism of marine environment to steel structure, marine environment can be divided into atmosphere area, splash area, tidal range area, full immersion area and sea mud area Zhisheng Weihua anti-corrosion technician found that due to the difference of corrosion factors in each area, the corrosion rate of steel structure along the longitudinal direction is different Relevant research shows that the marine splash zone has the highest corrosion rate due to the joint action of various corrosion factors, mainly due to the existence of severe stress corrosion conditions in the sea water splash zone above sea level, it is often corrosion The most seriously eroded part Splash zone refers to being at sea level Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings: the marine environment is a very serious corrosion environment for steel structures According to the corrosion mechanism of the marine environment for steel structures, the marine environment can be divided into the atmospheric area, splash area, tidal range area, full immersion area and sea mud area Zhisheng Weihua anti-corrosion technician found that due to the difference of corrosion factors in each area, the corrosion rate of steel structure along the longitudinal direction is different Relevant research shows that the marine splash zone has the highest corrosion rate due to the joint action of various corrosion factors, mainly due to the existence of severe stress corrosion conditions in the sea water splash zone above sea level, it is often corrosion The most seriously eroded part Splash zone refers to the part above the average high tide level of the sea water, which is alternately dry and wet due to tide, wind and wave Seawater is a very complex system, the splash zone is often wetted by saturated seawater, the surface electrolyte concentration is high, and the temperature is high under sunlight; The material surface and anti-corrosion protection layer are damaged and the corrosion is intensified by the alternation of oxygen rich spray impact and dry wet impact, the impact of floating objects on the sea surface, and the huge impact caused by the bubble burst when the sea water contacts the material surface The technical personnel of Zhisheng Weihua anti-corrosion coating pointed out that the corrosion of general steel materials is the strongest in this area, and the anti-corrosion protection layer is also the most easy to fall off For the steel structure in splash zone, the part above waterline and the part below waterline should be compared The part above waterline is cathode area, and the part below waterline is anode area Electrochemical corrosion also intensifies the safety performance of the steel structure above waterline Coating protection for offshore steel structure is the most economical and effective method, but the coating protection requires high surface treatment, and the commonly used coating is difficult to meet the requirements of long-term impact resistance The steel structure surface in service must meet the necessary coating requirements Therefore, the equipment height jointly developed by Beijing Zhisheng Weihua chemical Co., Ltd and the Research Institute of joint forces Zhisheng Weihua zs-711 inorganic heavy-duty anti-corrosion coating, which adopts the world's most advanced anti-corrosion cutting-edge technology, inorganic polymer chelating film-forming solution, based on the siloxy-si-o-si-bond, grafted organic alkyl side chain as auxiliary, and then hydroxyl as the end chain chelating film-forming material, has a good ternary synergistic effect on the hydroxyl and alkyl chelated on the silicon atom, The solution has strong stability, reduces the impact on the polymer interior, and the film-forming material is more compact, with strong adhesion and high temperature resistance At the same time, it has good weather resistance, corrosion resistance, acid rain resistance, good coating performance, easy to repair, good flexibility, excellent ductility, impact resistance and vibration resistance, and can be cured at low temperature It is suitable for the protection of steel structure in marine environment Because zs-711 inorganic anticorrosive paint anticorrosive pigment is composed of passivated metal particles, nano graphite scales, nano metal amphoteric oxides, ultra-fine rare earth ultra-fine powder, etc Through activation of these anti-corrosion pigments, Zhisheng Weihua inorganic anti-corrosion coating can resist corrosion and enhance polarization, has high acid and alkali resistance and corrosion resistance, plays a good role in neutralizing and preventing potential rise of substrate, and can also avoid the existence of coating pinholes The coating has high hardness, wear resistance and impact resistance, long acid and alkali aging time, that is, good electrochemical corrosion resistance Zs-711 inorganic anti-corrosion coating can react with atoms or ions on the surface of the object quickly after being chelated by inorganic polymer film-forming solution and highly activated anti-corrosion pigment It has the triple protective effect of physics, chemistry and electron, and can be firmly combined with the surface of the substrate through chemical bond and ion bond It has a good effect on the physical corrosion protection, chemical corrosion protection and electronic corrosion protection of the substrate This heavy-duty anticorrosive coating technology can greatly extend the maintenance cycle of offshore steel structure facilities, reduce maintenance costs, save manpower and material resources, improve the durability of structures, and extend the service life of steel structures Zs-711 inorganic anticorrosive coating has a wide range of adaptability to steel facilities exposed to the sea spray splash area In the marine environment, the corrosion in the spray area of steel facilities is the most serious, and it is also the weakest link in the current marine corrosion protection The corrosion of spray splashing area plays a decisive role in the service life of the whole steel structure It will not only cause corrosion damage and loss of functions of various infrastructures, equipment and structures, shorten the service life of materials and structures, but also cause huge waste of resources, materials and energy; And it will also lead to sudden disaster accidents, such as oil leakage, pollution of the marine environment, and even cause casualties Therefore, the development and promotion of strategic marine anti-corrosion technology is of great significance to the healthy and orderly development and construction of China's blue marine economy [focus on WeChat official account "paint net";
