The influence of 0-10% concentration of PP contained in PE on electric deterioration stability is investigated. It is shovn, that introduction of small concentration of PP into PE (1-2 weights %) increases stability versus eroision and oxidation cansed by electric charge action and leads to electric durability of PE. There is a hypothesis advanced, that for all mixtures of polymers in two – and three component systems, compatibile and uneompatibile, there is some fraction of medifier (for one of polymers up to 10%), at which, sharp, avalanche – like changing of structure and electrophysical properties will take place. These changes can be directed both improvement, and to deterioration of properties of initial parameters of polymers of composition.

 

Показана возможность получить эффект размягчения полос стали при холодном прокате под действием ультразвука. Прокат металлических полос при ультразвуковом воздействии является перспективным по сравнению с классическим видом проката, так как при этом повышается степень деформации, возрастает скорость проката и  увеличивается производительность.
