What is the stainless steel/enamel tank technology
Water tank anti-corrosion technology is very important for water heaters. The history of the development of water heater tanks is a history of the development of water tank anti-corrosion technology. When we walked into the electric water heater counter in the mall, we saw many names of tanks, such as "enamel tank", "Golden Gui tank", "Blue Gold Steel Tank", etc. In fact, these tanks basically use the enamel process, but the manufacturers give different names just to reflect a differentiated selling point. So far, the water heater tank has gone through three generations from the initial galvanized steel tank to the stainless steel tank and then to the enamel tank. Among them, the development history of electric water heater tanks is longer, with a history of decades or even hundreds of years.
At present, stainless steel tanks are almost extinct in the domestic and foreign markets, and enamel tank products are fully popularized. Due to the limitations of the development stage, most companies use stainless steel tanks for solar water heaters, which have certain advantages in the application of non-pressure solar water heaters and have a large market share.
Enamel tanks are new technology products. By enamel plating on the surface of thickened steel plate, it can withstand temperature changes in a large range, generally -60 ~ +450 ℃, and can withstand high temperature sudden changes. In terms of physical properties, it is resistant to pressure, tension, elastic, electrically insulating, and pollution-free; in terms of chemical properties, it is acid-resistant, alkali-resistant, high-temperature-resistant, and water vapor-resistant. Various ions cannot penetrate its surface, which can effectively ensure that the water quality is not polluted. Huashenglong, Guangmang, and Saidelong have developed enamel liner suitable for solar products based on the enamel technology of electric water heater liner, becoming representative companies of enamel liner products in the solar industry. In the past two years, the market share of enamel liner solar energy has increased rapidly, especially in the split pressure-bearing solar energy engineering market, showing outstanding performance, and has been increasingly valued by manufacturers and real estate developers, becoming the preferred product for pressure-bearing projects. In the future development of the solar water heater industry, pressure-bearing applications will become the dominant market. Due to the limitations of the industry's development stage, the industry has currently developed to the popularization period of stainless steel liner, and urgently needs to transition to the enamel liner period.
