Abstract
An aqueous blood adhesive used in the manufacture of plywood, comprises a substance capable of supplying magnesium ions, a substance capable of supplying cobalt ions and/or chromium ions, e.g. the sulphates and chlorides of magnesium cobalt and chromium, and a substance for rendering the adhesive alkaline, e.g. sodium and calcium hydroxides, sodium silicate or mixture thereof. The ions, which are preferably supplied as water-soluble metal salts, may be added in the dry or solution state to dry blood or to neutral or alkaline blood solutions. Defoaming agents, e.g. N-amyl or octyl alcohol and pine oil, and phenolformaldehyde resin may be present. The examples disclose aqueous blood compositions comprising: (2) magnesium and cobalt chloride hexahydrate and sodium hydroxide; (4) magnesium chloride hexahydrate, chromic sulphate and sodium hydroxide; (6) wood flour, pine oil (as defoamer), calcium and sodium hydroxides, sodium silicate, magnesium chloride hexahydrate, and cobalt sulphate mono-hydrate; (7) wheat flour, wood flour, sander dust, magnesium chloride hexahydrate, cobalt sulphate monohydrate, calcium and sodium hydroxides, and phenol-formaldehyde resin. Comparisons are made with adhesives containing substances supplying magnesium, cobalt and chromium ions singly.ALSO:An aqueous blood adhesive used in the manufacture of plywood comprises a substance capable of supplying magnesium ions, a substance capable of supplying cobaltand/or chromium ions, e.g. the sulphates and chlorides of magnesium cobalt and chromium, and a substance for rendering the adhesive alkaline, e.g. sodium and calcium hydroxides, sodium silicate or mixtures thereof.
