Abstract
237,292. Sveen, K. July 21, 1924, [Convention date]. Pulp, adding special substances to; waste products, treatment and utilization of; weighting.- Paper containing a percentage of filler larger than usual is produced with better retention of the fillers with better sizing by incorporating with the pulp an auxiliary substance which acts with the mordant to hold the filler and other constituents in the pulp of the paper. Auxiliary substances suitable for the process are those which form colloids with the mordants such as soap solutions especially of the fatty acids, rubber emulsion, gelatine, joiners' glue, glue from leather waste, fish glue, albuminous substances such as casein, and solutions of inorganic substances such as alkalies, ammonia, water glass, lime, calcium salts &c. As filler is mentioned china clay, mordanted with aluminium sulphate, and the best effect is produced when the filler &c. is added immediately before the pulp is supplied to the wire of the paper machine, preferably in the mixer, knot strainer or sand collector. Where glue solution is used, the solution is preferably stored at an ordinary or lower temperature for some days, and its effect may be increased by the addition thereto of lignin substances such as waste sulphite liquor. In the treatment of " save-all " water, the settling of the fibres therein can be accelerated by adding loading material such as china clay, or mordant such as aluminium sulphate, and an auxiliary substance.
