Production Of Paper From The Residue Of The Cellulose Extracted From The Corn Cob (Zea Mays L. Var. Ceratina)

Abstract

Paper was obtained from the cellulose from the corn cob (Zea mays L. var. Ceratina), the cob was subjected to a grinding and sifting process to obtain a particulate matter with a diameter of 120 um of average, for its extraction different proportions of sodium hydroxide were used for every 100 grams of raw material (1:5, 3:10, 2:5). The resulting pulp was dry at 95 Celsius grades later it was bleach with sodium hypochlorite at 45 Celsius grades for 0,75 hours. The sheets of paper dried on absence of light at room temperature were characterize obtaining as a result a grammage of 1,63 g/ square meters, rupture rate of 189 kgf, caliber of 1,152 mm and a whiteness index with a variation of reflectance of 13,61% in relation with the standard. The most optimal pulp process gave a performance of 44,73% and a kappa number of 32,88 with a proportion of 3:10 NaOH (Sodium Hydroxide) for 3 hours and a temperature of 95 Celsius grades stance, in addition to taking advantage of the modulable dissolution capacity.
