Definitions
- the present invention relates to a process for the recovery of paste from printed paper and chiefly wood paste.
- My said process is applicable to all classes of wood paper, and can also be used for the removal of ink from; all varieties of printed paper.
- the cellulose thus recovered can be 40 used for most of the purposes for which new .cellulose is employed.
- My said process comprises two essential stages, as follows:
- soluble soap i. e, an alkaline soap for instance 1 part in 2000.
- the color is taken up by the fatty substance and there is formed a black foam or scum on the surface of the liquid.
- the resulting paste is disposed'in a tank which, is heated by direct fire or b steam.
- the said tank contains a very wea solution of an alkaline salt.
- sodium carbonate of about 1 to 1500 strength; the proportion should never exceed 1 in 800, or the fibres would be attacked and yellowed.
- the said foam or scum is then eliminated either by skimming, by suction, by overflow discharge, or by like means.
- the said scum contains paper fibres,-a-nd it can thus be dried and compressed in order to form gray pasteboard (tarboard). Obviously, I-may recover the fatty substance, and even the coloring matter contained in the said foam or scum.
- the soap which is formed may be decomposed by the use of an acid whereby the fatty acids of the soap will be set free, and due to their small density, the said acids will collect on the surface.
- the ink removing solution a solvent for the ink, or substances capable of changmg the capillary action of the said solution, thus furthering the formation of the said scum; for instance, albumen, casein, gelatin, glucose, or the like, or substances changing the ittgture of the fibres, such as bleaching agen
- a solvent for the ink for instance, albumen, casein, gelatin, glucose, or the like, or substances changing the ittgture of the fibres, such as bleaching agen
