摘要 |
A method for manufacturing a glue in which physico-chemically changed animal blood or physico-chemically changed blood components are used as binding agent in the manufacture of cellulose-containing chipboard or as binding agent for panels to be covered with wood veneer. Whole blood is added in a known manner to a substance inhibiting coagulation. Immediately before mixing the blood with the cellulose-containing particles, a single additive in the form of monobasic organic acid is added in an amount such that a pH value between 3.0 and 4.0 and a wetting of the blood components results. The added monobasic organic acid is acetic acid or propionic acid or formic acid or locatic acid, or n-butyric acid or n-valerianic acid or n-caproic acid or n-heptoic acid or mixtures of these fatty acids or their hydroxy derivatives. The whole blood or blood components and the monobasic organic acid may be separately supplied to a nozzle and mixed during spraying. The two initial mixed materials may be dried for storage and used when needed by adding water and acid. |
