Chemical resistance of materials in synthesis of polyelectrolyte PKB-1

The development of a highly efficient cationic polyelectrolyte PKB-1 was examined. The corrosion resistance of a number of materials was tested and results tabulated. Type of corrosion on steels was determined visually and rate was determined gravimetrically and on the basis of penetration rate. In plastics and coatings, corrosion resistance was evaluated by defects, such as cracks, peeling and blistering. In tests on concrete, corrosion resistance was determined by defects and strength coefficient. Glass enamel coating and fluoroplastic F-4 were rated as resistant in the synthesis of polyelectrolyte PKB-1. Concrete and asbestos cement were practically identical in corrosion resistance.
