Rubber Recycling—Upgrading of Scrap Rubber Powder by Vulcanization. II

Abstract

Abstract Vulcanizates from scrap tires have interesting mechanical properties that widen the range of their uses. These properties and dynamic characteristics (compression modulus, damping coefficient) undergo great changes as sulfur percentage is varied. This fact is particularly important in regard to the design of damping devices for the vibration absorption of industrial machines. The size of the machine as well as the vibration frequency must be taken into account to optimize the transmissibility factor of the damped system. The favorable results obtained for our materials in the damping of impact noises and their small compressibility foreshadow an efficient application in resilient coverings in buildings. Rubber slabs when stuck directly on the floor can be covered with a thin coating consisting, for instance, of thin tiles. The resilient covering can also be stuck on the floor and covered with lean mortar, a traditional way of laying tile.
