1. The origin of single-head electric heating tube: (single-head) or (cartridge) electric heating tube (r). In China's electric heating industry, there is a long-term name for the model:. In the late 1990s, electric heating tubes were widely used in China, and many shapes of electric heating tubes appeared. In southern China, the electric heating tubes used in molds with one end out of the wire are called single-head electric heating tubes, which is very vivid. In foreign countries, it is called a cartridge heater, which is also a vivid name, because the cartridge shell is cylindrical and one end is blocked. It is a coincidence that it is called a single-head electric heating tube in China. The electric heating tube tubular heating element is a heating element in which a resistance wire is placed in a metal tube, and the surrounding gaps are tightly filled with crystalline magnesium oxide powder with good heat resistance, thermal conductivity and insulation, and then processed through other processes. Electric heating tubes have the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation and long service life. Electric heating tubes are now widely used in various saltpeter tanks, water tanks, acid-base tanks, air heating furnace drying boxes, hot molds and other devices. When choosing a heating tube, users should consider the heating medium and usage environment, and we will recommend the best design solution for the rest.
2. Advantages of single-head electric heating tube
Small diameter, can achieve -.
, the length is not limited, you can do -.
, high power, can achieve (surface area watts / square centimeter), foreign countries can even achieve (surface area watts / square centimeter).
3. Performance requirements of single-head electric heating tube

6. Single-head electric heating pipe potting glue
Single-head electric heating pipe within the degree
Insulation potting glue, this potting glue is made of epoxy resin As the main component, it has high insulation level, high hardness and good durability. The cured product is not brittle and has a beautiful black mirror finish.
, Single-head electric heating pipes above 100°C
[] High temperature glue, with temperature resistance up to ~°C. This product was originally used for gluing and sealing of valves, flanges, etc., and is now working with a certain manufacturer After communicating with the manufacturer of the single-ended electric heating tube, he recommended this product to them. After comparing the use of high-temperature glue from other companies, the manufacturer finally determined that our Shilin product can best meet his design requirements. They originally used The products are imported. Due to the long procurement cycle and untimely supply, and the high price of imported products, the cost problem has not been well controlled. After choosing our high-temperature resistant glue, the performance of the product can basically replace foreign products after proper proportioning and curing. It also provides favorable guarantees for their timely supply and cost control. Originally they needed to order three months in advance, but now they only need to order one working day in advance, which greatly shortens their ordering cycle.
Since then, the company has continuously improved this product to be closer to the requirements of the electric heating tube industry. Currently, in addition to the two products mentioned above, the products that can be used in this industry include durable high-temperature glue and durable high-temperature glue. Meet higher temperature design requirements. (Please contact the company's sales or technical personnel for specific operation plans)
