Description
Иавесгные способы обработки целлюлозы в виде рулонов, листов и другой формы требуют повыЪенного расхода этерифицирующих материалов, а получаема техническа целлюлоза имеет недостаточную реакционную способность при высокой степени весового набухани .Iavez processing methods for cellulose in the form of coils, sheets, and other forms require high consumption of esterifying materials, and the resulting technical pulp has insufficient reactivity with a high degree of weight swelling.
Предлагаемый способ позвол ет активизировать лрсидесс этерификации целлюлозы И расход &терифицированных peaгентов . Это достигаетс тем, что сухую или влажную целлюлозу обрабатывают под давлением на дифференциальных вальцах или /гастопрсжатных станках. При атом пе; люлозу подвергают сильному уплотнение, раздавливанию и истиранию.The proposed method makes it possible to activate the pulp esterification of pulp and the consumption of amputees. This is achieved by processing dry or wet pulp under pressure on differential rollers or gastropress machines. With atom ne; lulose is subjected to strong compaction, crushing and abrasion.
Установлено, что реакционна способность целлюлозы после указанных операций значительно повышаетс , а молекул рный вес ее несколько понижаетс . Така целлюлоза обладает, кроме того, замедленной кинетикой набухани , что имеет значение дл получени вискозных растворов в оаном аппарате .It has been established that the reactivity of cellulose after these operations increases significantly, and its molecular weight decreases somewhat. Such cellulose has, in addition, a slowed down swelling kinetics, which is important for the preparation of viscose solutions in a single machine.
Способ может быть использован в пронаводстве медно-аммиачногО волокна, ацетилцеллюлозы и других зфиров целлюлозы.The method can be used in the penetration of copper-ammonia fibers, cellulose acetate and other cellulose derivatives.
Формула взобрвтен Formula is taken
Способ обработки целлюлозы в виде руло нов, листов и другой формы, о г л и ч а xvш в и с тем, что, с целью t актвввэаоив процесса этерификации в сокращени рао« хоаа атерифицируюших материалов, сухую или влажную целлюлозу обрабатывают по« давлением на дифференциальных вальцах нл листопрокатных станах.The method of processing cellulose in the form of coils, sheets, and other forms, about xl and xvш and so that, in order to act in the esterification process in order to reduce the "atheatically acceptable materials, dry or wet cellulose is treated by" pressure on differential rollers nl plate rolling mills.
