In the process of heating water, the calcium and magnesium ions in the water condense on the surface of the high-temperature metal heating body, forming a scale for a long time. 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 when boiling water.
We usually use hardness to describe how many calcium and magnesium ions there are in water. Calcium and magnesium ions, which produce more scaling, are hard water, and soft water on the contrary. Different regions, including the hardness of different water sources (surface water or groundwater).
The scale erodes and condenses the metal heating tube, reduces the light heat efficiency, causes waste of electric energy, and the heavy heating tube bursts, endangering human life safety; The erosion of metal bile by scale can not be ignored, the light water output is small, and the heavy bile leaks, resulting in the scrapping of the entire water heater. The heating tube is the core component of heating the heating container, and its material and heating structure will directly affect the safety of consumers.
The following measures can be taken to delay limescale:
1. Considering the heating tube itself, it is generally recommended that the surface load of the customer should not be too high, that is, the power per meter should not be too high (the power per meter of the heating tube should be controlled within 2KW/meter) to reduce the surface temperature of the heating tube.
2. Secondly, stainless steel 304, 316, 310S or our company's anti-scale coating electric heating tube can use its own materials, which plays an important role in anti-scaling.
3. The electric heating tube cannot be burned dry.
