ABSTRACT

The article presents the results of studies aimed at assessing the efficiency of using pressing equipment that has a difference in design features, namely the ability to transmit load simultaneously in two and one direction, with equivalent pressing pressure. The relevance of the study is due to the validity of the choice of pressing equipment for the production of ceramics from hydro-removal ashes (HRAs). At the initial stage, the object of the research was a raw sample made from HRAs ThPP-10 on two types of pressing equipment, and then a ceramic sample obtained as a result of firing the raw material. The article presents the physical and mechanical characteristics of raw samples and ceramic samples, and evaluates their changes depending on the type of pressing equipment used in molding. It is shown that the strength of green samples obtained on pressing equipment capable of transmitting load in two directions is almost twice as high as the strength of green samples produced on pressing equipment providing pressure in one direction, 2.1 MPa versus 1.1 MPa, respectively. The influence of the type of pressing equipment on changes in the physical and mechanical characteristics of the ceramic shard is traced not so significantly, 75.4 MPa versus 72.3 MPa, respectively. The obtained research results indicate the fundamental possibility of industrial use of pressing equip-ment of both types. However, the use of pressing equipment capable of transmitting force in two directions simultaneously may be preferable, since ensuring the highest green strength for facing products is one of the key factors in ensuring surface quality.
