Производитель: "LAP Lambert Academic Publishing" Four different percentages, 0%, 0. 5%, 1. 0% and 1. 5% oven-dry weight of pulp of cationic starch (CS), were used in making pulp boards and tested for their physical and mechanical properties. Specific Gravity ranged from 0. 59 to 0. 64 but no significant difference was found at p=0. 05. Thickness Swelling ranged from 19. 69% to 43. 04% for 2-hours submersion in distilled water where 1. 0% and 1. 5% CS have significant differences. Submersion of additional 22-hours ranges from 19. 26% to 43. 76% where 0. 5% and 1. 0% CS have significant differences. Water Absorption has ranged from 181. 44% to 133. 87% and from 129. 94% to 265. 35% for 2-hours and 22-hours submersion respectively. Significant difference was found at 1. 0% CS for the 2-hours submersion. 0. 5%, 1. 0% and 1. 5% CS were found to be significant different after 22-hours submersion. Internal Bonding ranged from 0. 35 MPa to 0. 54 MPa but not significant. For Static Bending, the value ranged from 50. 71 N/mm2 to 202. 97 N/mm2 and from 2. 20 N/mm2 to...
