    The heating plate has multiple choices when purchasing
    Published:2022-02-26 Source:http://en.xinyicorp.com/cjwt/108.html

    The heating plate is made of stainless steel, ceramics and other materials as the outer shell, and the electric heating alloy wire is enclosed in the interior of the stainless steel heating plate, so it is closed heating, no open flame, no peculiar smell, and good safety. working environment. The heating material is electrothermal alloy wire, and the principle is very simple, that is, the basic electrothermal effect. When working, the electric current passes through the electric heating alloy wire, and the electric heating alloy wire will heat up, convert the electric energy into heat energy, and conduct it to the outer shell.

    Heating chips can be divided into three categories: stainless steel heating plates, ceramic heating plates, cast aluminum and cast copper heating plates, each of which has its own characteristics, among which:

    1. Stainless steel heating plate: The mica plate (mica sheet) heater utilizes the good insulation properties and high temperature resistance of the mica plate (mica sheet). The stainless steel plate is used for support and protection, and can be made into various types of heating devices such as plate, sheet, cylinder, cone, cylinder, and circle. The normal surface load is 2.5-3W, and the temperature resistance is 500℃.

    2. Ceramic heating plate: After the ceramic heating plate is energized, the surface heats up without being charged, and is widely used in light and heavy industries and household electric heating appliances. The ceramic-clad electric heater can be made into various shapes such as round rod, plate, tube, and camber. Its shape and texture are like ordinary household porcelain, but there are electric heating wires buried in it. Since the ceramic material used has good electrical insulation properties at working temperature, the surface is not charged, the leakage current is small during operation, and the use is safe and reliable.

    3. Cast aluminum and cast copper heating plates: Cast aluminum and cast copper heating plates can be divided into die-casting and casting. In occasions with many specifications and sizes, the casting process is generally used. High-purity aluminum blocks and copper blocks are used in casting production. They are changed from solid to liquid state by a high-temperature furnace, and then injected into a mold with a heating tube installed. After cooling and forming, they are made by finishing.
