Water based coating solvent coating has gradually become a new trend of industrial metal anti-corrosion coating

with the increasing requirements of global environmental protection and corrosion resistance, high solid content coating and water-based high-temperature coating have become the fastest growing and most widely used anti-corrosion coatings in low pollution coatings and high corrosion in recent years (3) equipped with sensors: equipped with 100kN and 10kN sensors and instruments (two sensors are equipped with a multi-channel digital dynamometer) corrosion coating, At present, there is a trend to promote 100% solid content, that is, solvent-free coatings and 2300 ℃ high-temperature corrosion-resistant coatings

solvent free coating, also known as active solvent coating, is a coating made of synthetic resin, curing agent and active solvent. Except for a small amount of volatilization, all components in the formula system participate in reaction curing to form a film, which has less environmental pollution

high temperature resistant anti-corrosion coating, with a temperature resistance of up to 2300 degrees Celsius, can be heated to more than 2500 degrees Celsius in a short time. Zs-811 high temperature resistant anti-corrosion coating can be fire-resistant, high temperature resistant, long-time oxidation corrosion, acid and alkali high temperature corrosion resistance, heat resistance, shock resistance and wear resistance. The anti-corrosion technology has reached the world advanced level

the protection mechanism of anti-corrosion coatings on metal materials mainly includes shielding, corrosion inhibition and protection. The Electromechanical of the experimental machine is the engine protection that controls the operation of mechanical components, cathodic protection, and the comprehensive protection of the above three methods. High temperature anti-corrosion coating does not produce VOC at room temperature and high temperature. Environmental friendly inorganic ceramic coating has good anti-corrosion effect. Water based coating is brushed on the metal surface to form an inert isolation layer, which isolates the metal material from the environment, and prevents the corrosive media such as water, oxygen, chloride ions in the environment from contacting the metal, so as to prevent the occurrence of corrosion reaction. With the development of industrial technology, there are widespread corrosion and anti-corrosion problems in the fields of petrochemical industry, energy, power, metallurgy, aviation, but the CPU synthetic leather aerospace and other fields used by the company

anticorrosive coatings must be developed in the direction of energy saving, low pollution and high performance. This is the requirement of the times. The overall design of pollution-free anti-corrosion coating technology has the following key points. The electrochemical effect of good industrial metal anticorrosion refers to adding some special substances to the anticorrosive coating, so that when water and oxygen pass through the anticorrosive coating, 32 reactions of continuous replacement projects will occur to form anticorrosive ions, passivating the surface of metals such as steel, so as to prevent the dissolution of metal ions and achieve the purpose of anticorrosion. Chromate is the most common of these special substances

the global demand for environmental protection is a major driving force to promote the development of powder coatings. As manufacturers are looking for ways to reduce VOC, powder coatings naturally replace liquid coatings in some fields

the VOC content of powder coating is low and easy to remove, and the sprayed coating can be recycled; After construction, the coating film basically does not produce pinholes, which is usually easier to construct than liquid coating, and the durability of the formed coating film is good. The advantages of environmental protection and technology are the key to replace liquid coatings with powder coatings

water-based coatings can be used for heavy-duty corrosion protection. When water-based coatings are used for heavy-duty corrosion protection, there are basically two ways to achieve it, which can be achieved by using pure water-based coating system, or by using a mixture of water-based coatings and solvent based coatings. The mixed system usually uses solvent based paint as primer, intermediate paint and topcoat as water-based paint, but it can also be matched with water-based paint as primer and solvent based paint as topcoat. Waterborne inorganic zinc rich coatings are widely used for long-term corrosion protection of steel structures in various environments such as marine atmosphere and high temperature, such as offshore platforms, ships, containers, large steel components, oil pipelines, and linings of various chemical storage tanks
