Resumen: | En este estudio se evaluó las fuerzas de adhesividad y de cáscara de un pegante. El pegante se realizó con almidón nativo de yuca (Manihot sculenta Crantz) variedad M-Tai y se usó hidróxido de sodio como agente hidrolizante. En la elaboración del pegante se evaluaron cinco soluciones de almidón nativo de yuca (10, 20, 30, 40 y 50% p/v) y cuatro concentraciones de NaOH (0, 0.66, 1.33 y 2 % p/p). Los resultados indicaron que las uniones papel-papel, cartón-cartón y papel- vidrio, realizadas con los pegantes hechos con 40 %-2 %, 40 %-0 % y 50 %-0 % p/v-p/p de almidón de yuca y NaOH, respectivamente, presentaron mayor fuerza de adhesión. Las uniones papel-papel, cartón-cartón y papel-vidrio que mostraron mayor fuerza de fricción, como un indicativo de mayor durabilidad del pegamento, fueron los pegantes realizados con 50 %-2 %, 50 %-1.33 % y 50 %-2 % p/v-p/p de almidón y NaOH, respectivamente. El pegante a base de almidón de yuca no presentó diferencias significativas (p < 0.05) con tres adhesivos comerciales (Colbocol, Supertack y Pegajoso), teniendo mejor adhesividad y durabilidad en las uniones hechas con los sustratos papel-papel y papel-vidrio. |
Abstract: | In this study, the adhesive and shell forces of a glue were evaluated. The glue was made with native cassava starch (Manihot sculenta Crantz) variety M-Tai and sodium hydroxide was used as a hydrolyzing agent. In the preparation of the glue, five solutions of native cassava starch were valuated (10, 20, 30, 40 and 50 % w/v) and four concentrations of NaOH (0, 0.66, 1.33 and 2 % w/w). The results indicated that the paper-paper, cardboard-paperboard and paper-glass joints, made with the adhesives made with 40 %-2 %, 40 %-0 % and 50 %-0 % w/v -w/w, of cassava starch and NaOH respectively, showed higher adhesion strength and the paper-paper, cardboard-paperboard and paper-glass joints, which showed greater frictional force as an indication of greater durability of the glue, were the glued with 50 %-2 %, 50 %-1.33 % and 50 %-2 % w/ v - w/w, of starch and NaOH respectively. The paste based on cassava starch did not present significant differences (p<0.05) with three commercial adhesives (Colbocol, Supertack and Pegajoso), having better adhesiveness and durability in the bonds made with paper-paper and glass-paper substrates. |
