How to effectively deal with the scale produced during the use of the electric heating tube?
Environmental protection is an eternal topic. As the country attaches importance to environmental protection, our company is also vigorously improving the current traditional electric heating tube technology to achieve as low energy consumption as possible. Today we will explain the process of using stainless steel electric heating tubes. , Especially when the water is heated, scale is easy to form on the surface, especially in some areas with poor water quality, scale formation is fast. The formation of scale will cause many disadvantages.
The accumulation of scale will surround the heating tube layer by layer. The thermal conductivity of scale is very low, resulting in waste of electricity. At the same time, due to the large amount of scale and poor thermal conductivity, the internal temperature of the electric heating tube is too high, which will greatly shorten the service life of the heating tube. Generally speaking, electric heating tubes with a service life of 3 years can only be used for half a year to 1 year when there is too much scale. In addition, scale is easy to breed bacteria and pollute the water quality. In severe cases, it can also cause the surface of the heating tube to burst and damage, causing the risk of electric shock.
Here is a brief introduction to several methods to reduce the formation of scale.
Its characteristic is that it does not change the external shape of the heating tube, the power is not limited, and the technical parameters of the ordinary heating tube are roughly the same. The characteristic is that a layer of anti-scaling coating is added to the surface of the stainless steel heating tube. The effect is very obvious.
The use of an elongated steel core extruded magnesium rod and placing it on the opposite side of the electric heating tube can effectively extend the service life of the magnesium rod, ensure maximum protection of the inner tank, and prevent the electric heating tube from scaling.
The quartz glass electric heating tube with enlarged diameter is adopted. The water quality in the north is hard and the water is easy to scale. Because the quartz glass electric heating tube is made of high-purity silicon dioxide, the physical and chemical properties of silicon dioxide are not active. When heated, it is not easy to absorb impurities. In addition, the quartz glass electric heating tube is in the heating process. It emits far infrared rays in the middle, which can play a certain role in softening water quality, so this kind of electric heating tube is not easy to form scale.
Use instant water heaters. The water temperature of the instant water heater is controlled at 50 degrees, which is the critical temperature for scaling. When taking a bath, it is lower than this temperature (usually 35 to 45 degrees), so it is difficult to build scale. Even in northern areas where the water hardness is relatively high, long-term use only slightly scales.
