Description
Technical Field
The utility model relates to a water heater pressure-bearing water storage container field especially relates to electric water heater, air can water heater and solar water heater's holding water tank.
Background
At present, most of heat preservation water tanks of domestic electric water heaters and solar water heaters adopt enamel coating inner containers or stainless steel inner containers without anticorrosive coatings, and although the enamel coating has the function of corrosion resistance on the water tank, the enamel coating is a brittle coating and is easy to crack when being collided, so that the inner container of the water tank is corroded. When the water temperature changes, the internal pressure of the water tank also changes, the liner also expands and contracts to a certain degree, and the brittle enamel coating is easy to crack due to the different expansion coefficients of the enamel coating and the steel plate liner, so that the corrosion prevention effect fails, and the liner is corroded and leaks water. In addition, the enamel coating is easy to accelerate corrosion in the environment with water temperature above 80 ℃, and the phenomenon of pinhole-shaped corrosion occurs. Because the enamel liner needs to use special steel plates for enamel, the selection of materials is limited, and the cost is increased.

In order to solve the technical problems, an anti-corrosion coating needs to be coated in the stainless steel inner container. Before coating the anticorrosive coating, the metal surface is pretreated to increase the adhesive force between the coating and the metal surface, and the method is generally carried out by adopting a sand blasting or chemical phosphating method. The application of the corrosion protection coating is generally carried out by wet spraying using high-pressure atomization or dry spraying using an electrostatic adsorption process. Whether surface pretreatment is carried out on the inner wall of the inner container or spraying of the anti-corrosion coating is carried out, because the inner wall of the inner container is operated, the inner container cannot be effectively fed into equipment, spraying dead angles and observation cannot be carried out (in the existing mode, spraying liquid or spraying powder is poured into the inner container through a water inlet of the inner container), once the surface pretreatment is not in place or the anti-corrosion coating is not uniformly sprayed, the overall quality and stability of the anti-corrosion coating are seriously influenced, and particularly, once the thickness of the anti-corrosion coating on the surface of a workpiece is non-uniform, and accumulated liquid or accumulated powder bulges and foams, the coating quality is seriously influenced.
