The importance of high temperature resistance of chimney anticorrosive coatings
Chimney is one of the common facilities in the industry, and its working environment is very harsh, often affected by high temperature, high humidity, corrosion and other factors. In particular, the high temperature environment can have a great impact on the anti-corrosion coating of the chimney. Therefore, it is important to choose a chimney anticorrosive coating that can withstand high temperatures. The high-temperature resistant chimney anticorrosive coating can maintain good stability in the high-temperature environment, and is not easy to decompose, oxidize and other reactions, which can effectively protect the chimney surface from corrosion and prolong the service life of the chimney.
Technical requirements for high temperature resistance of chimney anticorrosive coatings.
High-temperature resistant chimney anticorrosive coatings need to meet the following technical requirements:
1.Good heat resistance: In a high-temperature environment, anticorrosive coatings are not prone to thermal decomposition, thermal oxidation and other reactions, and can maintain stable chemical properties.
2.Excellent adhesion: The anti-corrosion coating should have good adhesion to the surface of the chimney and not easy to fall off.
3.Good abrasion resistance: Anticorrosive coatings should have good abrasion resistance to resist the erosion of particles in the flue gas.
4.Good corrosion protection: Anticorrosive coatings should be able to effectively prevent the erosion of the chimney surface by corrosive media (such as acids, alkalis, salts, etc.).
5.Environmental protection: Anticorrosive coatings should be non-toxic, odorless and environmentally friendly.
Classification of chimney anticorrosive coatings.
At present, there are many kinds of chimney anticorrosive coatings on the market, which can be divided into the following categories according to their temperature resistance:
1.Solvent-based anticorrosive coatings: The main film-forming substances of this kind of anticorrosive coatings are solvent-based resins, which have good weather resistance and corrosion resistance, but the general temperature resistance is below 100.
2.Water-based anticorrosive coatings: This kind of anticorrosive coatings use water as a diluent, which is non-toxic and tasteless, and environmentally friendly, but generally has a temperature resistance of less than 100.
3.Ceramic anticorrosive coatings: This type of anticorrosive coatings are composed of ceramic powder and organic polymer materials, which can be used in high-temperature environments, but ** is higher.
4.Fluorocarbon anticorrosive coatings: These anticorrosive coatings have super weather resistance and corrosion resistance, and can be used in extreme environments, but they are also high.
New anti-corrosion coating for high-temperature chimneys.
In response to the demand for high temperature resistance of chimney anticorrosive coatings, we have developed a new type of high-temperature resistant chimney anticorrosive coatings. The coating is made of a special silicone resin and inorganic filler, which can be used for a long time in a high temperature environment of 300 meters, and has good heat resistance, adhesion and abrasion resistance. In addition, the anticorrosive coating is non-toxic, odorless, environmentally friendly, and relatively low, with a high cost performance.
To sum up, choosing a high-temperature resistant chimney anticorrosive coating is crucial for industrial production. The new high-temperature resistant chimney anticorrosive coating developed by us has good performance and high cost performance, which can effectively protect the chimney surface from corrosion and prolong the service life of the chimney. In the future, we will continue to devote ourselves to the research and development of better anticorrosive coatings to provide more reliable guarantee for industrial production.
