Lo mkhiqizo 2-i-hydroxypropyl ether methyl cellulose, okuwumkhiqizo owenziwe nge-semi-synthetic. Ingakhiqizwa ngezindlela ezimbili: (1) Ngemva kokwelapha ama-linter kakotini noma imicu ye-wood pulp nge-caustic soda, ixutshwa ne-chloromethane kanye ne-epoxy Propane isabela, icolisisiwe futhi igaywe ukuze iwuthole; (2) Sebenzisa izinga elifanele le-methyl cellulose ukuze welaphe nge-sodium hydroxide, usabele nge-propylene oxide ngaphansi kwezinga lokushisa eliphezulu nokucindezela okuphezulu kuze kufike ezingeni elifanele, futhi ulicwenge. Isisindo samangqamuzana sisuka ku-10,000 siye ku-1,500,000.
★ Umqondo wemvelo ohlanzekile, uthuthukise ukugaya nokumuncwa.
★ Amanzi aphansi, 5% -8%. Ukumelana nokumuncwa komswakama okuqinile, okuqukethwe akulula ukukuhlanganisa, futhi igobolondo le-capsule akulula ukuligoba, libe brittle, futhi libe lukhuni.
★ Ayikho ingozi yokusabela kokuxhumanisa, akukho ukusebenzisana, ukuzinza okuphezulu, njengoba i-hydroxypropyl methylcellulose iphuma ku-cellulose, abukho ubungozi bokusabela okuxhumanisa izinto zamaprotheni ku-gelatin.
★ Izidingo eziphansi zezimo zokugcina:
Icishe ingabi brittle endaweni enomswakama ophansi, inozinzo oluhle emazingeni okushisa aphezulu, futhi i-capsule ayigogeki.
★ Izindinganiso ezifanayo kanye nokuhambisana okuhle:
Kusebenza kumazinga e-pharmacopoeia kazwelonke, ukuma, usayizi, ukubukeka kanye nendlela yokugcwalisa ilingana nama-capsules angenalutho we-gelatin, futhi asikho isidingo sokushintsha imishini nezingxenye.
★ Umthombo okungewona owesilwane, ayikho ingozi engaba khona ye-hormone yokukhula noma izidakamizwa ezisele emzimbeni wesilwane.
I-Hydroxypropyl methylcelluloseamaphilisi angenalutho ahlukile kuma-capsules angenalutho we-gelatin. Ziyi-hydroxypropyl methylcellulose (HPMC) eyenziwe ngokhuni. Ngaphezu kwezinzuzo zomqondo ohlanzekile wemvelo, i-hydroxypropyl methylcellulose amaphilisi angenalutho futhi Ingathuthukisa ukumuncwa nokugaya amaprotheni, amafutha nama-carbohydrates, futhi inezinzuzo zobuchwepheshe kanye nezici ezingenazo amaphilisi e-gelatin angenalutho. Ngokuthuthuka okuqhubekayo kokuqwashisa kwabantu ngokuzinakekela, ukuthuthukiswa kokuthanda imifino, ukuqedwa kwesifo senkomo esihlanyayo, isifo samatele empilweni yomuntu, kanye nomthelela wenkolo nezinye izici, imikhiqizo yama-capsule yemvelo emsulwa kanye nezitshalo. izoba yinkomba ehamba phambili yokuthuthukiswa kwemboni ye-capsule. .
