Resumen
En este trabajo, se propone el desarrollo de recipientes biodegradables para cultivos que puedan ser trasplantados directamente y actuar como fertilizantes. Se eligió gelatina bovina como material base, que se procesó en una mini mezcladora-inyectora junto con una solución concentrada de urea que actuó como plastificante. Se realizaron estudios reológicos y de tracción para evaluar la inyección de las mezclas y las prestaciones mecánicas relacionadas con la aplicación propuesta. Considerando que estos materiales biodegradables tienen baja resistencia al agua, se propuso incrementar la estabilidad de los recipientes mediante recubrimiento superficial. Asimismo, se estudió y analizó su influencia en el contenido de humedad, materia soluble e hinchamiento en agua destilada. Se observó que las muestras recubiertas fueron significativamente más estables en agua que las muestras control, lo que evidencia la buena calidad y homogeneidad del recubrimiento, que avala la factibilidad del sistema seleccionado y su potencial desarrollo de contenedores biodegradables
In this paper, the development of biodegradable containers for crops that could be transplanted directly and act as fertilizers is proposed. Bovine gelatin was chosen as the base material, which was processed in a mini-injector mixer with a concentrated urea solution acted as a plasticizer. Rheological and tensile tests were performed in order to evaluate the injection of gelatin based formulations and mechanical properties related to the proposed application. Taking into account that biodegradable materials have a low water resistance, the increment of container stability was proposed using a surface coating. In addition, the influence of moisture content, the soluble matter and swelling were studied and analyzed. It was observed that coated samples were significantly more stable than the control ones, which guarantees the feasibility of the selected system and its potential development of biodegradable containers.
