Description
Ceramic heater is a kind of heater with high efficiency, even heat distribution and insulation performance.it is directly printed conductive resistance paste on ceramic green billet, laminated and arranged glue, and co-fired into a whole product at high temperature.Heater ceramic itself and production process meet the requirements of environmental protection. Compared with the traditional alloy heating wire, PTC heating element has many advantages, such as simple structure, rapid temperature rise, large power density, safe use, corrosion resistance, long service life, etc.
Screw in ceramic heating element is constructed by winding a nickel-chrome resistance ribbon around mica/ ceramic insulation and encapsulated in a stainless steel sheath. It is then formed to the desired diameter for installation over a dies, barrels and nozzles. They are available in an extensive variety of sizes and shapes with options for holes, notches and cut-outs. A number of threaded terminals, wire lead options and terminal boxes offer great flexibility for field wiring.
Ceramic band heater is a kind of high temperature and long life heater, ceramic heater can adapt to modern industry in the higher and higher working temperature requirements.Especially chemical fiber, engineering plastics, plastic machinery, electronics, medicine, food and ect.
Screw in ceramic heating element is composed of spiral resistance wire passing through specially designed high temperature resistant ceramic tile, precision extension, flexible, beautiful metal shell ceramic fiber insulation layer. An effective high temperature, high power density, strip heater is designed to be flexible and easy to install.
Process
(1) Preparation of ceramic matrix, step
(2) preparation of heat resistance material
(3) combination of ceramic matrix and heat resistance material: The prepared alumina raw porcelain substrate resistance film is coated on the exterior of the ceramic matrix and the conductive paste is printed, and then a 1000℃ temperature sintering, the control time is 10 ~ 20 minutes, next the precious metal paste is printed, 1500℃ temperature sintering, the control time is 5 ~ 10 minutes. Realize the ceramic matrix and heating resistance material fully combined in one.
Feature
Applications:
●Holding Tanks
●Injection and Blow Molding Machines
●Plastic Extruders
Construction
Screw in ceramic heating element is designed with spirally wound inner resistance coils evenly threaded through interlocking insulated ceramic “tiles”. The ceramic core, or “mat” of tiles is housed beneath a stainless steel sheet with serrated edges. This combined assembly of the Ceramic Band Heater offers a flexible heating system that yields efficient transmission of conduction and radiated heat. The heat of the Ceramic Band originates from the inner coils that conduct heat at maximum temperatures. The heated coils evenly deliver heat through the ceramic tiles which radiate energy to the barrel. We offer a variety of Ceramic Band styles with customized configurations.
Ceramic heater is developed to meet industrial requirements for high temperature long lasting heaters. They are ideally suited to comply with today's new resins, which calls for ever-increasing process temperatures.
An additional advantage of the heater ceramic is that they transfer heat through conduction and radiation. This makes their tightness on barrels less critical; thus they are less prone to thermal expansion problems.
Theoretically, there are no restrictions on the diameter that ceramic band heaters can attain; however, because these heaters utilize ceramic tiles that are available only in specific lengths, the width of these heaters falls within a certain incremental range of size
FAQ
