Embodiment 1

[0013] The inner surface of the metal body of the inner tank of the water heater is degreased with a cleaning solution, and then sandblasted. Pour the prepared liquid of organic ash polytetrafluoroethylene mixture into the spray filter system, and when the spray gun is at an angle of 45-90°, start the spray filter system to spray the coating liquid on the inner surface of the metal body. Bake in an oven at 280°C for 10 minutes. As a result, its inner surface is covered with a homogeneous coating of the machine dusted polytetrafluoroethylene mixture. The thickness of the coating was measured to be 12 microns.

Embodiment 2

[0015] The inner surface of the metal body of the inner tank of the water heater is degreased with a cleaning solution, and then sandblasted. Pour the prepared PTFE base oil into the spray filter system, and when the spray gun is at an angle of 45-90°, start the spray filter system, spray the liquid on the inner surface of the metal body, and put it in an oven at 150°C Inside, bake for 4 minutes. Press the technique of embodiment 1 again, spray polytetrafluoroethylene top oil. As a result, its inner surface is covered with a uniform coating of polytetrafluoroethylene. The thickness of the coating was measured to be 25 microns.

Embodiment 3

[0017] The inner surface of the metal body of the inner tank of the water heater is degreased with a cleaning solution, and then sandblasted. Pour the prepared polytetrachlorethylene powder into the electrostatic powder spraying system, start the electrostatic powder spraying system, spray the powder on the inner surface of the metal body of the water heater liner, and bake it in an oven at 280°C for 10 minutes. As a result, its inner surface is covered with a uniform coating of polytetrachlorethylene. The thickness of the coating was measured to be 12 microns.

Abstract

This invention is an internal-bladder of a heater of anti-fouling ability. On the surface of the internal bladder covers a layer of anti-fouling organic coating. The material of the internal bladder is either normal steel or alumina alloy or stainless steel. The cost of the anti-fouling internal bladder is low, while the anti-fouling ability is premium and low pollution. It can be used to electric heater or solar heater.

Description

technical field [0001] The invention relates to a water heater inner tank. Especially the water heater liner with anti-scaling performance. It is suitable for electric water heaters and solar water heaters, and belongs to the water storage container of the above products. Background technique [0002] Technical problems existing in the inner tank of the water heater: [0003] Existing two kinds of water heater liner, 1, have the water heater liner of enamel coating. The metal body is made of ordinary carbon steel metal plate, and then the inner surface of the body is enamelled. 2. Stainless steel water heater liner. The inner tank of the water heater is directly made of stainless steel plate through deep drawing and welding. The liners made by these two processes generally have the disadvantage of being prone to scaling. The existing anti-scaling technology adopts the measure of "anodic anti-corrosion", and converts "hard water" into soft water through the treatment of...
