Abstract

Objective: This study investigates the physicochemical properties of polymer composite materials based on recycled PET and CaCO3. Method: The thickness of the samples was selected in compliance with the standard requirements: 3,49 mm for sample 1, 3,43 mm for sample 2, and 3,91 mm for sample 3.The experiment was initiated at an ambient temperature of 22,5°C, with a controlled heating rate of 50°C per hour. Under an applied load of 10 N, the penetration of the needle to a depth of 1 mm for the first sample was achieved after 118,68 minutes, corresponding to a temperature of 152,4°C. Results: The results indicate that optimal performance is achieved at 5–15% CaCO3, demonstrating the potential of recycled PET composites for cost-effective industrial applications. Novelty: The results indicate that optimal performance is achieved at 5–15% CaCO3, demonstrating the potential of recycled PET composites for cost-effective industrial applications.

Abstract

Objective: This study presents the results of zinc hydroxide carbonate production through precipitation from a zinc nitrate solution using an 18% sodium carbonate solution. Method: The effects of key process parameters on the precipitation efficiency were systematically examined, and optimal operating conditions were determined. Results: The initial zinc nitrate solution contained 13,16% ZnO. The highest precipitation efficiency of zinc hydroxide carbonate was achieved within a pH range of 7,9–8,3 and at a temperature of 65–70°C. Additionally, extending the process duration from 40 to 45 minutes led to an increase in the precipitation degree from 98,79% to 99,96%. Novelty: The effects of key process parameters on the precipitation efficiency were systematically examined, and optimal operating conditions were determined.
