Abstract

Egy papírgyártó gépen megvalósított papírgyártási eljárás azzaljellemezve, hogy egy cellulózos híg törzs szuszpenziót biztosítanak, aszuszpenziót úgy pelyhesítik, hogy a szuszpenzióhoz a természetes ésszintetikus polimerből választott polimer retenciót segítő anyag vizesoldatát adják és így egy pelyhesített szuszpenziót kapnak, apelyhesített szuszpenziót nyíró hatásnak teszik ki, a nyírtszuszpenziót újra pelyhesítik oly módon, hogy vizes újrapelyhesítőszuszpenziót adnak hozzá, az újrapelyhesített szuszpenziót lecsapoljákegy szitán keresztül, hogy lemezt kapjanak és a lemezt megszárítják, afolyamatot az jellemzi, hogy nyírás után és szárítás előtt aszuszpenzióhoz lényegében teljesen főtt keményítőt adnak.
