| Tóm tắt: | Title from the title-page. Technological processes of flexible polymer materials destruction are based on their transition to the brittle state after deep freezing, for example, in liquid nitrogen. In this case even insignificant physical loading can cause their destruction. Currently, cooled polymers are destructed in mechanical mills. This requires the construction of special devices where grinding media shall work perfectly in deep freezing conditions. The investigation of dielectric strength of liquid nitrogen and flexible polymers of different thickness put into liquid nitrogen proved the possibility of their destruction technology creation due to the electric breakdown and the creation of mechanical stress field from the expanding discharge channel. This can allow the destruction of both uniform and composite materials. Investigation results of breakdown voltage of liquid nitrogen and samples prepared from several types of rubber and other flexible polymer and biological materials cooled up to 77 °K are presented in the given paper. Energy characteristics of flexible materials mass disintegration reaching the powder state are considered. Режим доступа: из корпоративной сети ТПУ Text files |
