THE POSSIBILITIES OF USING ZEOLITES IN VARIOUS FIELDS (REVIEW)

Zeolites, due to their unique properties, have a wide range of applications. Fillers are one of the most important components of rubber compound formulations, allowing effective impact on the complex of chemical, technological, physical-mechanical and economic indicators of rubbers. Zeolite occupies a special place in this class of fillers. The purpose of this review is to analyze existing works on the study of the properties and application of zeolites for their further study as a promoting system. In recent years, active research has been carried out to create new types of promotional systems based on mineral raw materials. A characteristic feature of inorganic adhesion promoters is their ability to slowly release metal ions, which has a positive effect on the efficiency of fastening rubber to brass-plated metal during operation. This makes it possible to introduce metal salts in significant dosages without undesirable effects, especially mineral ones, which is caused mainly by the relative cheapness of the feedstock.In this aspect, zeolites have long attracted the attention of researchers as minerals with specific properties and structural features.Of all the more than 52 mineral species and varieties of zeolites known in nature, only a few meet the requirements for use for practical purposes, namely, they form large, almost monomineral concentrations and at the same time have the corresponding useful properties: high adsorption capacity, cation capacity, acid and heat resistance. Zeolites can be considered a multi-purpose raw material due to the diversity of material and chemical compositions, textural and structural characteristics, physical, mechanical and adsorption properties. And for the successful use of any mineral raw materials in various industries, a detailed study of their textural and structural characteristics is necessary, as well as a search for new ways to increase beneficial properties using modern technological methods and techniques.
