Technical Field

[0001] The utility model relates to the technical field of electric heating tubes, in particular to an electric heating tube film spraying device. Background Technique

[0002] An electric heating tube is a tubular electric heating element (abbreviated as an electric heating tube), which is an electric appliance element that specifically converts electrical energy into heat energy. It uses a metal tube as the shell (including stainless steel and copper tubes), and a spiral electric heating alloy wire (nickel-chromium, iron-chromium alloy) is evenly distributed along the central axis inside the tube. Its gap is filled and compacted with magnesia sand with good insulation and heat conduction performance, and both ends of the tube orifice are sealed with silica gel. This metal-sheathed electric heating element can heat air, metal molds, and various liquids. Common electric heating tubes include finned electric heating tubes, finned electric heating tubes, finned electric heating tubes, Teflon electric heating tubes, quartz electric heating tubes, etc. Due to its low price, convenient use, easy installation, and no pollution, it is widely used in various heating occasions. The electric heating tube on a water heater generally uses a quartz tube as the base body, and an electric heating film solution is coated on the quartz tube to have the performance of conducting electricity and generating heat.
