Abstract

PROCEDURE FOR THE PREPARATION AND USE OF CALCIUM SULPHATE DIHYDRATE IN CRYSTALLINE FORM FROM CALCIUM SULPHATE HEMIHYDRATE FOR PAPER MANUFACTURE. STOP FROM THE ADDITION OF SO4CA 1/2 H2O, CALLED A LONG CRYSTALS WHICH, BY ADDING THEM TO A WATER DISPERSION OF CELLULOSIC FIBERS, JOIN THEM. SURFACE PRODUCERS, EMULSIONANTS, DISPERSANTS, ACCELERANTS OR RETARDANTS MAY BE ADDED TO CONTROL THE SPEED AND DIMENSION OF THE CRYSTALS. (Machine-translation by Google Translate, not legally binding)
