    摘要： A process for producing compacted free-flowing nitrocellulose based lacquer raw materials is described. The process involves pressing a nitrocellulose based lacquer feed material, which is moistened with alcohol or water, through the holes of a die. The pressing step may be performed by means of at least one circulating breaker. The process optionally comprises shearing off the compacted lacquer raw material into pieces of selected length, below the die. The compacted nitrocellulose based lacquer raw materials prepared by the process of the present invention are free flowing and have a moisture content of at least 25%.

    摘要： PROCESS OF PREPARING NITROCELLULOSE GRANULES HAVING A BULK DENSITY OF BETWEEN 0.4 AND 0.6 G./CM3 FROM A NITROCELLULOSE LACQUER PREPARED BY STIRRING UNDER WATER NITROCELLULOSE STABILIZERS AND A NITROCELLULOSE SOLVENT INSOLUBLE IN THE WATER, ADDING TO THE LACQUER STILL BEING STIRRED A PROTECTIVE COLLOID AND A WATER-SOLUBLE ALKALI METAL OR ALKALINE EARTH METAL SALT, THEREAFTER REDUCING THE STIRRING SPEED WHEREUPON THE LACQUER BREAKS UP INTO DROP-LIKE PARTICLES, FURTHER REDUCING THE STIRRING SPEED AS TO CAUSE THE PARTICLES, OF LACQUER TO FLOW TOGETHER AGAIN,MAKING A SECOND ADDITION OF PROTECTIVE COLLOID AND SALT, THEN INCREASING THE STIRRING SPEED CAUSING THE LACQUER TO BREAK UP AND FORM THE DESIRED PARTICLES AND THEREAFTER DISTILLING OFF THE SOLVENT.
