protective covering

The current article is focused at the physical and technical properties of ceramic bricks. It was established that the decisive factors in the process of interaction of ceramic bricks with water, water solutions and water vapor is the composition of pore structure and energy state of its surface. It is substantiated and defined the component composition and technological regime of the protective coating formation on the surface of ceramic bricks. The technological properties of the initial composition and physico-mechanical properties of coatings based on them are established.

Research conducted in the article investigates phase and structural modifications in the process of protective coating forming while heating. There are examined patterns of processes of interaction between silicium organic compounds based on the rich polymethylphenylsiloxane with oxide excipients as well as opportunities of their utilization for high-temperature and fire-protection of constructions made of reinforced concrete.

In the article there are substantiated and determine the optimal composition of protective covering by the mathematical planning method with taking into account the influence of protective covering on water absorption, adhesive strength and frost resistance. It is constituted technologic regime of marking and hardening protective covering on the ceramic matrix surface. It is determined the depth of protective covering penetration and its role in the adhesive contact formation during hardening process and its dependence from ceramic matrix structure.
