The concept of electric heating pipe

The metal tubular electric heater element (electric heating tube) is an electric heating element placed in a metal tube. The heating tube manufacturer is tightly filled with crystalline magnesium oxide powder with good heat resistance, thermal conductivity and insulation in the gap. Processed. It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, long service life, no pollution, cheap price, etc. At the same time, it saves power and is safe to use. It can be bent into various shapes, light and easy to disassemble. It is widely used in various saltpeter tanks, water tanks, oil tanks, acid and alkali tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying boxes, hot stamping molds and other heating equipment. It is especially suitable for portable household electric heating appliances.

Will the ceramic heating sheet PTC heating sheet explode?

There is a failure mode of PTC heating film called breakdown, and there is a popping sound accompanied by strong light during breakdown.

Generally speaking, the PTC heating sheet will have an external insulation structure. When the breakdown occurs, there is only a very small popping sound. You will not see strong light, and it will not hurt people.

The most common cause of breakdown is thermal breakdown due to insufficient PTC withstand voltage levels.

After the breakdown, the PTC heating sheet failed, and there was no way to repair it except for replacement.

Ceramic heating plate test index

1. Good oxidation resistance and strong corrosion resistance

2. Small heat loss in non-radiating surface during use

3, the substrate is heated to 800 ℃ and placed in cold water repeatedly dozens of times without cracking

4. The radiant element is heated up to the rated power after being energized, and immersed in cold water forty times without power loss without loss

5.The energy saving effect is more obvious than silicon carbide
