STUDY OF THE STRUCTURAL AND MECHANICAL PROPERTIES OF SAMPLES BASED ON MAGNESIUM OXIDE FORMED IN THE PROCESS OF POLYMERIZATION OF ORGANIC BINDER
The article presents the results of a study of the influence of humidity, oxygen on the formation of the structure and strength properties of products based on magnesium oxide and organic binder SFPR-054. It has been established that carrying out the polymerization process at a temperature of 25 ?C without access to air increases the strength of the samples by about 5 times compared to samples polymerized in dry form at a temperature of 300 ?C. The obtained results suggest that the increase in the structural and mechanical properties of products based on magnesium oxide will be facilitated by the moistening of the mixture, the settling of the pressed product and the polymerization process in an oxygen-free environment or in an atmosphere of water vapor.
