Improving the Chemical Resistance of Polyethylene Materials for Packaging and Storage of Materials of Liquid Potatic Chemicals
Abstract: In the process of the work, it has been carried out research of polyethylene containers for transportation and storage of liquid toxic chemicals, it has been determined chemical resistance and antioxidant stabilization by differential scanning calorimetry (DSC) according to ASTM D 3895-98. As a result of research it has been observed an increase in the chemical resistance of PE containers to the effects of corrosive liquids, namely: the use of polyethylene (PE) stabilized with antioxidants with an increased oxidation induction value; the use of PE with a higher degree of crystallinity, not prone to significant changes. This effect is achieved by the introduction of dispersed additives and ultrasonic treatment. Creation of internal protective layers. These are layers of chemical-resistant material (fluoroplastic, polyamide), as well as layers obtained on the surface of PE through its special processing in order to harden and eliminate defects.
Keywords: chemical resistance, polymeric material (PM), polyethylene (PE), low pressure polyethylene (LPPE), antioxidant, oxidation induction (OIT), differential scanning calorimetry (DSC) method, artificial nucleation structure (ANS).
