Özet
Calcite, an industrial raw material, is used as filler mineral in many sectors. In general, the calcite, which is comminute to micronized sizes, is subjected to a surface modification process to convert its hydrophilic structure to a hydrophobic structure. Thus, the product price of micronized+coated calcite increases, while it is better suited to the structure and to improve the final product characteristics in the areas where it is used. Micronized calcite production is performed in grinding circuits and coating is carried out in another process. The surface modification process is based on the method of coating the surface with a coating agent and different coating systems have been developed on the industrial scale. In this study, current information about the surface modification mechanism of calcite, processes, and equipment used are given and application examples are examined. The tests, quality control processes and previous studies performed in the coated calcite sector are presented in Part II. © 2020 Union of Chambers of Engineers and Architects of Turkey.
