Which is the best comparison between the inner tanks of the electric water heater?
After the electric water heater is purchased, with the increase of service life, the chances of water leakage, burst and other accidents are rising continuously. Therefore, in choosing the electric water heater, especially should pay attention to the following two aspects.
At present, most enterprises on the market are using enamel inner liner. Inner enamel surface layer of enamel, not rust. But the low carbon steel plate used in general enamel liner has only two layers of bile, and there are many problems such as scale explosion, acid corrosion and quick dissolution, and the service life is low. Therefore, in the choice of enamel liner also pay attention to. Quality of inner enamel mainly depends on the processing technology, as for the formulation of enamel powder, just kick up a cloud of dust. As everyone knows, recipes are open as long as they are patented. The three layer is a common diamond currently on the market is relatively good, it adopts special enamel powder, after 890 degrees high temperature sintering, finally forming a dense layer containing three bile, enamel layer, dense layer, decarburized plate layer, the anti solubility, resistance, acid resistance is greatly improved, thereby prolonging products service life.
Don't be confused by all kinds of namesAt present, there are only two kinds of inner liner for electric water heater. One is stainless steel liner, and the other is enamel inner liner. The so-called Kim kyu titanium liner, liner, quartz, sapphire and enamel, but changed the name.Stainless steel liner has the advantages of high temperature resistance, corrosion resistance, and stable performance, not easy to rust, but it is difficult to weld, easy to leave the weld, a long time, the weld is easy to rust, resulting in leakage. Some enterprises in order to reduce costs, the use of stainless steel is also very thin, so that the liner to withstand pressure drop, affecting the service life.
Good liner, strong impact resistanceIt is not difficult to find that the inner liner is the core part of the life of electric water heater, and the gap between the brands is still very large. Experts advise consumers: in the purchase of electric water heaters, we must pay attention to the liner "impact resistance" this indicator. The water quality in our country is very complicated, pressure fluctuations, liner impact resistance is directly related to the quality of the products and service life, so when the purchase, be sure to choose a good product liner impact resistance. For the impact resistance of the liner, Chinese enterprises have been able to do 160 thousand times, higher than the United States and European standards (the United States standard is 100 thousand times).
