Electric boiler heating body generally use which inner tank? Let's take a look at it with Xiaobian.
Galvanized sheet inner liner: zinc protective layer is only 0.06mm, the inner liner is not anti-rust treatment after forming, easy to rust, short life.
Hot-dip galvanizing coated with anti-rust resin inner liner: After forming the inner liner, the thickness of zinc alloy protective layer is more than 0.7mm, and the surface of zinc containing gold is then covered with anti-rust resin, which has a short life.
Oxygen free copper inner tank, the application of instant electric water heater has incomparable good characteristics: It has fast heat conduction, pressure and corrosion resistance, good ductility, antibacterial and antibacterial, oxygen-free copper heating system is generally used in the developed areas of Europe and the United States, most international brands are using copper production of hot electric water heater heating body, copper material special physical and chemical characteristics, with rapid heating stability, high thermal efficiency characteristics. It is a mature and stable heater in line with the trend of environmental protection and health recognized in the world's hot water heater industry.
Stainless steel inner liner, good material, not easy to rust, but the weld hidden trouble is not easy to find, after multiple thermal expansion and contraction, the chromium in stainless steel will be corroded by chloride ions in tap water, a long time may leak at the welding;
The enamel on the surface of the enamel liner is a non-metallic material, which does not rust and is corrosion resistant. The thick steel plate is used as the liner, which has strong pressure resistance. The high-glaze coated steel liner has good anti-corrosion and heat preservation performance and longer life.
