Are controlled the discharge Characteristic poly acrylic Acid granulation and to its manufacturing method

摘要

(57) Abstract This invention is something regarding with the method in order to form the poly- acrylic acid granule and the granule which then is formed, there is a flowability in these granules, it possesses the bulk density which increases by comparison with the poly- acrylic acid which was polymerized, the quantity of the dust which is characterized generally as the particle which passes 325 mesh screens and in the long-cherished desire bill is small. Although the discharge characteristic tablet which is controlled, the discharge characteristic medicine tablet which especially is controlled is manufactured to use it is possible the granule which is formed by the method of this invention. Following to the method of this invention, the discharge characteristic where the tablet which was formed from the granule which is manufactured is controlled about is more unexpected than the tablet which is manufactured from the granule which was formed by other known granule conversion method is satisfactory.
