Ceramic band heaters are not made by ordinary mica wire-twisting, but by ceramic wire-piercing, so the power of the product is 0.5-1.5 times higher than that of ordinary products. The heating body is made of imported round silk pottery, which is flexed into a spring and inserted into the ceramic strip. The outer cover is made of stainless steel made in Japan, and the insulation cotton (aluminum silicate fiberboard) is used in the middle to prevent temperature leakage. The ceramic bar is a high frequency ceramic which has the characteristics of fast heat transfer, hard and fragile, high temperature, no deformation, and no aging.
Brief performance of ceramic band heaters: It is mainly suitable for extrusion, casting and punching machine operation temperature can reach 450 degrees, the maximum surface load 6.5W/cm. Features are long life, high temperature resistance, energy consumption reduced by 30%, high insulation, is the most suitable extruder, injection molding machine, film blower electric heating products.
Ceramic band heaters have the advantages of easy installation, fast heat transfer, good insulation, and no limitation of type and size. High working temperature, fast heating, high thermal efficiency, no pollution, uniform and accurate heating. The specific advantages are as follows:
It has winding property, such as heating vessel or pipeline, can be bended into arc or circle wrapped on the surface of heating, such as heating large workpiece, local wrapped form, large workpiece can be used flat cover form. In addition, it can be used for heating various geometric shapes.
High working temperature, fast heating, high thermal efficiency, pollution-free, uniform and accurate heating, can achieve automatic control.
High mechanical strength, good thermal insulation performance, large contact surface with heated object and long service life.
Easy to install and maintain, low cost, even if the internal heating
material is damaged, and external ceramic devices can still be reused.
