Mica Insulated Extruder Belt Heaters
This nozzle heater features a 5-inch-long, heat-free rear section that eliminates defects in the adapter area due to overheating. A heavy-duty spring-loaded clamping pin tightens the ends of the heater and keeps them running. Stainless steel braid attached to the copper arch is available in configuration 016.
In the transition or compression zone, heating is controlled by a series of heating tapes (usually 3 to 6 bands). It is located directly behind the front and consists of the second third of the total length of the heating cylinder. The correct temperature is the average of the front and rear area. The belt mica heater consists of a stainless steel housing with a resistance cable inside wrapped around a layer of mica. We use only the best nickel-chromium cables like Kanthal with high electrical resistance. The ceramic heating mat, together with the 6 mm thick ceramic fiber insulation, is mounted in S.
Some of the special options you can consider are the double-wire metal mesh, the two-piece construction, and the expandable one-piece construction. Mica heaters are efficient and economical solutions for the Mica Band Heater Manufacturer heating needs of many applications. Mica tape heaters are constructed with precision-wound nickel-chromium resistance wire around a mica plate, which is then placed between two additional mica blades.
Micanit insulation offers high thermal conductivity and high dielectric resistance. Sometimes belt heaters are made removable and consist of two half rings. They are usually designed to cover the entire surface of the drum or container.
Ceramic tapes are recommended here, as efficient heat transfer is not impaired by uneven surfaces or loose adjustments. At higher wattage densities, they can be used in larger steps than other heaters. This means that you can reduce the number of tapes used and simplify wiring. Sinus-Jevi belt heaters combine lightness, compactness and are used in applications that require a rapid rise in temperature. They can also be used in plastic injection molding, since the process of materials requires high heating power and high temperatures.
Drum furnaces are usually designed for the storage and heating of four to 24 drums, which are usually stored in groups of four on pallets to facilitate insertion and removal with the forklift. Belt heaters are used for contact heating in machines and for heating molds and tools, mainly in the plastics, foundry and rubber industries. Omega’s high-performance heating tape for processing high-temperature engineering resins. The first improvement in ceramic heaters since the introduction of Omega’s “Insulation Plus”TM in 1975.
Shows that when LDPE is heated from 20 °C to 190 °C, the change in enthalpy is 485 kJ/kg. While the temperature displays vary from machine to machine, they all convey the same information. •Tip: Transfer lines should be equipped with insulation to reduce heat loss.
