The principle of mica band heater
Mica heating ring is an efficient heater with uniform thermal division. It is made of metal alloy with excellent thermal conductivity, which ensures uniform temperature of hot surface and eliminates hot and cold spots of equipment. It has the advantages of long life, good thermal insulation performance, strong mechanical properties, corrosion resistance and magnetic field resistance. The external heat dissipation surface is added with thermal insulation device, and the internal heat dissipation surface is sintered with infrared ray, which can save 35% of electricity.
Properties and applications of mica heating rings
1, product features: with simple processing, reliable work, convenient use, rapid heating, high thermal efficiency, low power consumption, long service life, production is not limited by the size of the model and specifications, etc.
2, product use: widely used in plastic machinery, packaging printing, petrochemical, electronic equipment and other industries.
3, stainless steel electromica heating ring with 0.3~0.5mm stainless steel plate as the shell, in the middle of high insulation and high temperature resistant mica plate as the core, evenly around a variety of standard specifications of nickel chromium alloy resistance wire as heating body, processed into various shapes required by the molding machine. According to user requirements of the connection mode, voltage from 110V, 180V, 220V, 380V, the highest power load per square 3.5W. The external heat dissipation surface is added with thermal insulation device, and the internal heat dissipation surface is sintered with infrared ray, which can save 35% of electricity. Stainless steel mica heating ring has ring type and plate - like specifications.
