Microwave-Infrared Rubber Vulcanization Line

Microwave-Infrared Rubber Vulcanization Line

Microwave-Infrared Rubber Vulcanization Line is the process of converting natural rubber and similar elastic polymers into durable by cross-linking the polymer molecules, i.e. building additional bridges between them through the addition of sulfur or other equivalent “curatives.”

Microwave-Infrared Rubber Vulcanization Line is an advanced industrial technology that is intended to vulcanize rubber products precisely and efficiently. By combining microwave and infrared heating techniques, this modern technology speeds up the vulcanization process, improving product quality and cutting production time.

Uncured natural rubber is sticky, deforms easily when warm, and is brittle when cold and hence is very poor in elasticity. Vulcanized materials are less sticky and have superior mechanical properties. The process is named after Vulcan, the Roman God of Fire. A vast array of products are made with Microwave-Infrared Rubber Vulcanization Line including tires, sealings, shoe soles, hoses etc.

This process of rubber vulcanization can be carried out by the following 2 heating systems:
  • Infrared Heating System
  • Microwave Heating system

Infrared Heating System in Rubber Curing:

Microwave-Infrared Rubber Vulcanization Line is highly efficient for the pre-vulcanization of profiles and hoses. Arranged between the rubber extruder and the continuous vulcanization line, the high power infrared radiation pre-cures the surface of the rubber products. This is related to a better dimensional stability and an excellent surface quality. Typically these systems are about one meter long and have got a heating capacity of about 30 kW. However, rubber is a poor conductor for thermal energy and hence there was a high demand of microwave heating systems.

Microwave Heating System in Rubber Curing:

Microwave-Infrared Rubber Vulcanization Line has been a vastly popular application of Microwave Heating. While there are also types of cold vulcanization, microwave systems are always used for hot vulcanization. The continuous vulcanization of rubber profiles is the main application of microwave vulcanization systems. As the heat transfer in other heating systems only takes place through the surface of the product, the heating process is time consuming and can lead to negative effects like over-curing etc. In order to shorten down the vulcanization time and to avoid possible problems, these parts can be pre-heated using microwave ovens, as the radiation penetrates the rubber and heat the material from core to surface simultaneously and hence microwave curing is very fast.
