Problems solved by technology

Stainless steel inner tank, the manufacturing process is more complicated: shearing plate-punching-drum-welding seam-welding various workpieces-foaming insulation layer, and its corrosion resistance, poor acid and alkali resistance, easy to scale, welding parts are prone to high temperature Oxidation and corrosion, eventually causing the water tank to leak until the entire water heater is scrapped
The enamel liner is made by coating and firing a layer of inorganic ceramic glaze on the ordinary steel plate. The cost is moderate, the processing technology is high, and air bubbles or pinholes are easy to occur during the production process. Phenomenon
In addition, enamel will gradually dissolve and peel off in hot water, which is technically called "boiling water weight loss". Over time, enamel falling off will pollute water quality, rust and leak.
It can be seen that the manufacturing process of the above two liner materials is complicated, the cost is high, and there are quality risks
[0003] Recently, it has become a hot spot in material science research to study and prepare materials from the perspective of biomimetic, improve and enhance the performance and reliability of materials. Changes to promote the performance of the inner tank. The titanium gold inner tank and Jingui inner tank developed in recent years are improved enamel inner tanks. Compared with ordinary enamel inner tanks, their corrosion resistance and inner tank strength are significantly higher. Improvement, but still can not meet the needs of the industry and people's consumption needs

Description

technical field [0001] The invention relates to the technical field of water heater enamel liners, in particular to a healthy electric water heater. Background technique [0002] At present, water heaters on the market mainly have two inner tank materials, stainless steel inner tank and enamel inner tank. Stainless steel inner tank, the manufacturing process is more complicated: shearing plate-punching-drum-welding seam-welding various workpieces-foaming insulation layer, and its corrosion resistance, poor acid and alkali resistance, easy to scale, welding parts are prone to high temperature Oxidation and corrosion will eventually cause the water tank to leak until the entire water heater is scrapped. The enamel liner is made by coating and firing a layer of inorganic ceramic glaze on the ordinary steel plate. The cost is moderate, the processing technology is high, and air bubbles or pinholes are easy to occur during the production process. Phenomenon. In addition, ename...
