Efecto de la adicion de diferentes agentes plastificantes en las caracteristicas finales del PVC (policloruro de vinilo)

Abstract

In the present investigation, it was proposed to evaluate the effect of the addition of different plasticizing agents on the final characteristics of PVC. To carry out the research, the sample size was 10 units, the PVC was produced in the Icoplast plant and the quality analysis of the samples were carried out in the ESPOCH tannery laboratory, both located in Riobamba. Next, the resistance to tension, bending, lastometry and fracture was evaluated, of which the corrugated PVC obtained the highest performance with means equal to 970.33 N / cm2; 204.58%, 11.00 cycles and 460.97 N / cm2 respectively. The chemical tests constituted the evaluation of the presence of chlorine ions, nitrogen ions, smoke characteristics, smoke pH and density. In the first 3 tests there was no variation while for the remaining tests the best treatment was when the corrugated PVC with responses equal to 7.85 and 2.43 g / ml respectively. In the cost benefit ratio, corrugated PVC was the best with responses of 1.41. The effect of the addition of different plasticizers and their effect on the final characteristics of the polymer of the three treatments proposed in the investigation were evaluated. It is recommended to combine plasticizing agents with some additives.
