DETERMINATION OF THE STRENGTH OF ADHESION BETWEEN THE STRUCTURAL COMPONENTS OF CONVEYOR BELTS.

The properties of the basic materials of conveyor belts and adhesion between these materials affect the proper functionality and service life of conveyor belts. Their reliability depends on the adhesive force between their structural components. The purpose of this paper was to investigate into the quality of adhesion of the rubber cover layers to the carcass, and of the adhesion between the adjacent textile plies in a rubbertextile conveyor belt. The experiments were aimed at measuring the adhesive force using the tensile testing machine with a constant rate of traverse. The investigation was carried out with 4 conveyor belts with carcasses made of the same material. The experiments were carried out in compliance with the recommendations of the ISO 252:2007 standard and the results were verified according to the ISO 14890:2013 standard. The strength of adhesion between textile plies of the carcass and rubber is very important in the both production and applications of rubber-textile conveyor belts. [ABSTRACT FROM AUTHOR]
