Rubber before vulcanization, there is no cross-linked between molecules, so the lack of good physical and mechanical properties, practical value is not significant. When rubber is added to the vulcanizer, it can be treated by heat treatment or other means to produce cross-linked between rubber molecules, forming a three-dimensional mesh structure, so that its performance is greatly improved, especially the fixed extension stress, elasticity, hardness, tensile د ربړ ځواک او د فزیکي او میخانیکي ملکیتونو یو لړ د شربت میکروبرمانینډ سلفر سره په کلکه وده کوي. {{5}
د روبندۍ په پروسه کې وروستی پروسه ده، کولی شي د ربړ محصولاتو عملي ارزښت سره وروزل شي
