Magnesium Oxide Based Structural–Mechanical Properties of Samples Formed on Organic Binder Polymerization: A Study

The influence of humidity and oxygen on the formation of the structure and strength properties of manufactured products based on magnesium oxide and the organic binder SFPR-054 was studied. It was ascertained that conduction of the polymerization process at 25°C without access to air effects approximately five-fold higher sample strength compared to the samples polymerized in dry form at 300°C. The data obtained suggest that an increase in the structural and mechanical properties of manufactured products on the basis of magnesium oxide contributes to moistening of the batch, retention of the pressed product and the polymerization process in an oxygen-free environment or in an atmosphere of water vapors.
