Description

technical field [0001] The invention relates to the technical field of electromagnetic heating, in particular to a method for manufacturing an electromagnetic heating device and a device thereof. Background technique [0002] The word "vulcanization" has its history. It was named after the initial natural rubber products were cross-linked with sulfur as a cross-linking agent. With the development of the rubber industry, it can now be cross-linked with a variety of non-sulfur cross-linking agents. Therefore, the more scientific meaning of vulcanization should be "cross-linking" or "bridging", that is, the process of forming a network of polymers through cross-linking of linear polymers. In terms of physical properties, it is the process of converting plastic rubber into elastic rubber or hard rubber. The meaning of "vulcanization" includes not only the actual crosslinking process, but also the method of producing the crosslinking. Vulcanization is the last process in rubber...

AI Technical Summary

Problems solved by technology

[0005] At present, the vulcanizers and hot presses commonly used in the product industry are mostly heating plates in the form of electric heating tubes / heat transfer oil / steam. This heating method has the following problems: 1. The thermal efficiency is low. Since the electric heating tube is a resistance The heating method in the form of heat, its heating efficiency itself is low

In addition, due to the complex heat conduction process, the electric heating tube-plate-mold-mold rubber vulcanization, the heat loss is relatively large, the thermal efficiency is only 15-25%, and the energy waste is serious

2. Since the temperature measuring element is close to the heat source (electric heating tube), the temperature measured and controlled is quite different from the vulcanization temperature of the rubber. With the change of the ambient temperature, the temperature error is about 5-20 degrees, which seriously affects The vulcanization quality of the product is improved

3. The electric heating tube is a vulnerable component with a high damage rate

When one or several electric heating tubes are damaged, it is difficult to timely, resulting in uneven heating of the plate, which affects the scrapping of the product

Its maintenance volume and maintenance cost are also relatively large
