Calender Working Principle

- Jul 12,2018 -

One of the necessary working conditions of the calendering process: the friction angle ρ of the rubber compound and the roller must be greater than the contact angle α, and the rubber compound is pulled into the roller distance. For example, in the process of calendering, the four-roll calender is operated at a certain speed ratio, so that the rubber material is further kneaded and the plasticity is increased, and finally, it is calendered to have a certain thickness and width by the minimum roll pitch. Film; under the action of the pressing force of the roller, the film is pressed onto the textile or the steel cord. Some need to be pressed into a certain pattern and shape, and some need to combine multiple layers of different uses, colors, and shapes.
