In the process of heating water, the calcium and magnesium ions in the water will be heated and decomposed on the surface of the metal heating body at high temperature, and for a long time, they will form scale.The formation of scale is directly related to the concentration of calcium and magnesium ions in water. The more calcium and magnesium ions, the more scale will appear when the water is boiled.
We usually use the term "hardness" to describe the amount of calcium and magnesium ions in water.Calcium magnesium ion is much, generate scale much, it is hard water, on the contrary is soft water.The hardness varies in different areas, including different sources (surface water or groundwater) in the same area.
To prevent the water scale, we can take the following measures:
1. Considering from the heating element itself, we generally recommend that the customer's surface load should not be too high, that is, the power per meter of the heating tube should not be too high (the power per meter of the heating tube should be controlled within 2KW/ meter), so as to reduce the surface temperature of the heating element.
2. Secondly, the material itself can be made of stainless steel 304,316,310S or using anti-scaling coating electric heating element. This electric heating element plays a great role in anti-scaling
3. Softening water.
