Method for adding particles to raw rubber and other polymers

摘要

Method of dosage and mixing of solid particles to non-vulcanized rubber or other polymeric materials. A stud extruder is utilized as a mixing unit, wherein the quantity of rubber or polymer added is measured continuously, and the particle quantity supplied to the extruder is measured continuously in relation to the consecutive quantity of rubber or polymer added. The method is particularly applicable to the addition of abrasive particles to rubber for the production of friction tyres or antiskid soles for shoes.
