It is difficult to simply determine which high-temperature resistant coating has the highest cost-effectiveness, as it depends on specific application scenarios, performance requirements, and budget factors. The following is an analysis of high temperature resistant coatings with high cost-effectiveness in different application scenarios:Industrial equipment anti-corrosion field
Organic silicon based high-temperature resistant coating: The price is relatively affordable, generally around 20-100 yuan per kilogram. It can maintain good performance in the temperature range of 200 ℃ -600 ℃, with good corrosion resistance, weather resistance, and electrical insulation. It is also easy to apply and can be sprayed or brushed. Suitable for anti-corrosion protection of petrochemical equipment, power equipment, industrial furnaces, etc., it is a cost-effective choice in this field.
ZS-1041 smoke anti-corrosion coating: The price may be slightly higher than that of organic silicon based coatings, but the performance is excellent. It can withstand temperatures up to 750 ℃ and has excellent corrosion resistance. It can effectively resist the corrosion of H ₂ S and other media in flue gas, as well as acid-base corrosion in equipment such as flues. It also has characteristics such as wear resistance and strong adhesion. For equipment anti-corrosion in harsh environments such as chimneys and flues, the cost-effectiveness is outstanding.
Aerospace and high-end machinery fields
Ceramic based high-temperature resistant coating: Although the preparation cost is high and the price is expensive, it can withstand high temperatures of over 1000 ℃ and has extremely high hardness, wear resistance, and chemical stability in applications such as thermal components of aerospace engines and high-temperature wear-resistant components of high-end machinery. It can ensure the performance and service life of components under extreme working conditions. From the perspective of long-term use and performance guarantee, the cost-effectiveness is actually very high.
Metal based high-temperature resistant coating: When applied to components such as gas turbine blades and high-temperature valves, the price is slightly lower than that of ceramic based coatings. It can maintain good strength, toughness, and oxidation resistance at high temperatures, and has strong adhesion with the metal substrate. It can effectively improve the high-temperature resistance and service life of components, and the cost-effectiveness is also considerable.
Civil kitchenware field
Teflon coating: widely used in non stick cookware and other civilian kitchen utensils, with a relatively low price. Generally, non stick cookware priced around 100 yuan can meet the daily needs of ordinary households. It can be used continuously between -200 ℃ and 260 ℃, with strong non adhesiveness, wear resistance, corrosion resistance, light weight, and easy cleaning. Although the service life is relatively short, usually 1-2 years, for ordinary households, the replacement cost is not high and the cost-effectiveness is good.
Ceramic coating: It has the advantages of high temperature resistance, wear resistance, high safety, good non adhesiveness, and easy cleaning. However, the cost is high, the price is expensive, and the service life is relatively short, which makes it easy to crack. But for some consumers who have high requirements for appearance and safety, and have sufficient budget, choosing ceramic coatings on civilian kitchen utensils also has a certain cost-effectiveness.
