Resumen: | Se caracterizaron las propiedades fisicoquímicas del Polietilentereftalato en estado amorfo, obtenido de excedentes industriales, para la fabricación de botellas no retornables. De lo anterior, se definió para el peletizado una viscosidad intrínseca de 0.538 +/-0.024 dL/g, concentración de acetaldehído de 4.00+/-2.00 ppm, densidad de 1.53 +/-0.05 g/cm3 e índice de fluidez de 129 +/-22 g/10min. En segundo lugar, se determinaron las propiedades fisicoquímicas y mecánicas de preformas y botellas no retornables de 2L, fabricadas con la dosificación actual de 3% de PET en estado amorfo. Se obtuvo 0.830+/-0.015 dL/g de viscosidad intrínseca, 2.32 +/-0.605 ppm de concentración de acetaldehído, resistencia a la compresión vertical de 29.98 +/- 1.72 kg-F y, sin falla de ninguna botella en la prueba de resistencia a la presión interna a 135 psi durante 13 segundos. |
Abstract: | The physicochemical properties of polyethylene terephthalate in amorphous state, obtained from industrial surpluses, for the manufacture of non-returnable bottles were characterized. From the above, an intrinsic viscosity of 0.538 +/- 0.024 dL / g, acetaldehyde concentration of 4.00 +/- 2.00 ppm, density of 1.53 +/- 0.05 g / cm3 and melt index of 129 +/-22 g/10min was defined for pelleting. Second, the physicochemical and mechanical properties of preforms and non-returnable 2L bottles, manufactured with the current dosage of 3% PET in amorphous state, were determined. It was obtained 0.830 +/- 0.015 dL / g of intrinsic viscosity, 2.32 +/- 0.605 ppm of acetaldehyde concentration, resistance to vertical compression of 29.98 +/- 1.72 kg-F and, without failure of any bottle in the test of internal pressure resistance at 135 psi for 13 seconds. |
