Inkinga yokushisa ye-HPMC ye-HPMC

Mayelana nenkinga yokushisa kwe-gel yeI-Hydroxypropyll methyl cellulose hpmc, abasebenzisi abaningi abavami ukunaka inkinga yokushisa kwe-gel ye-hydroxypropyllylylylylylylylylylylylylylylylylylyll methyl cellulose. Kulezi zinsuku, i-hydroxypropyllylylylylylyllls ngokuvamile ukuhlukaniswa ngokuya ngokubonakala kwayo, kepha ngenxa yezindawo ezithile ezikhethekile kanye nezimboni ezikhethekile, akwanele ukukhombisa ukubonwa komkhiqizo. Lokhu okulandelayo kwethula kafushane izinga lokushisa le-gel le-hydroxypropyllylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylylyll methyl cellulose.

Inani le-Methoxyl Group lihlobene ngokuqondile nezinga le-cellulose sout, futhi okuqukethwe kwe-Methoxyl Group kungashintshwa ngokulawula ifomula, izinga lokushisa nesikhathi sokuphendula. Ngasikhathi sinye, izinga lokungasebenzi lithinta izinga lokufaka esikhundleni se-hydroxyethyl noma i-hydroxyproppyl. Ngakho-ke, ukugcinwa kwamanzi kwe-cellulose ether ngokushisa okuphezulu kwe-gel kuzoba mpofu. Le nqubo yokukhiqiza idinga ukuhlolwa, ngakho-ke akukhona ukuthi izindleko zokukhiqiza ze-cellulose ether ziphansi uma okuqukethwe kwe-methoxy kuphansi, kunalokho, intengo izoba ngaphezulu.

Ukushisa kwe-gel kunqunywa amaqembu we-methoxyl, futhi ukugcinwa kwamanzi kunqunywa ngamaqembu we-hydroxypropoxy. Kunamaqembu amathathu angenakuqhathaniswa ku-cellulose. Thola izinga lokushisa elifanelekile lokusebenzisa, ukugcinwa kwamanzi okufanele, bese unquma imodeli yale cellulose.

I-GEL lokushisa liyiphuzu elibucayi lokusetshenziswa kweI-Cellulose Ether. Lapho izinga lokushisa elizwakalayo lidlula izinga lokushisa le-gel, i-cellulose ether izohlukaniswa namanzi bese ilahlekelwa ukugcinwa kwayo kwamanzi. Ukushisa kwe-gel kwe-cellulose ether emakethe kungahlangabezana nezidingo zendawo yokusebenzisa udaka (ngaphandle kwezindawo ezikhethekile). Ngokwami ​​ngicabanga ukuthi akudingekile ukunaka ngokukhethekile inkomba yokusebenza kwamazinga okushisa we-gel lapho usebenzisa udaka. Vele, ukukhiqizwa kwabakhiqizi beCellulose Ether kumele bakubone.
