I-Hydroxypropyl Methylcellulose (HPMC)iyi-polymer encibilika emanzini evame ukusetshenziswa embonini yezemithi, yokudla, yezimonyo, kanye neyokwakha. Okuqukethwe komswakama kwe-HPMC kudlala indima ebalulekile ekucutshungulweni nasekuzinzeni kwayo. Kuthinta izakhiwo ze-rheological, ukuncibilika, kanye nokuphila kweshalofu kwezinto. Ukuqonda okuqukethwe komswakama kubalulekile ekwakhiweni kwayo, ekugcinweni kwayo, kanye nasekusetshenzisweni kwayo kokugcina.
Okuqukethwe komswakama we-HPMC
Okuqukethwe komswakama kwe-AnxinCel®HPMC ngokuvamile kunqunywa yizimo zenqubo kanye nezinga elithile le-polymer esetshenzisiwe. Okuqukethwe komswakama kungahluka kuye ngezinto zokusetshenziswa, izimo zokugcina, kanye nenqubo yokomisa. Ngokuvamile kuvezwa njengephesenti lesisindo sesampula ngaphambi nangemva kokomisa. Ekusetshenzisweni kwezimboni, okuqukethwe komswakama kubaluleke kakhulu, njengoba umswakama owedlulele ungaholela ekuwohlokeni, ekuqhekekeni, noma ekusebenzeni okuncishisiwe kwe-HPMC.
Okuqukethwe komswakama kwe-HPMC kungasukela ku-5% kuya ku-12%, yize ububanzi obujwayelekile buphakathi kuka-7% no-10%. Okuqukethwe komswakama kunganqunywa ngokomisa isampula ekushiseni okuthile (isb., 105°C) kuze kube yilapho ifinyelela isisindo esingaguquki. Umehluko ngesisindo ngaphambi nangemva kokomisa umele okuqukethwe komswakama.
Izici Ezithinta Okuqukethwe Komswakama ku-HPMC
Kunezici eziningana ezingathonya okuqukethwe komswakama kwe-HPMC:
Izimo Zomswakama Nezokugcina:
Umswakama ophezulu noma izimo zokugcina ezingafanele zingandisa okuqukethwe komswakama kwe-HPMC.
I-HPMC i-hygroscopic, okusho ukuthi ivame ukumunca umswakama emoyeni ozungezile.
Ukupakishwa nokuvalwa komkhiqizo kunganciphisa ukumuncwa komswakama.
Izimo Zokucubungula:
Izinga lokushisa lokomisa kanye nesikhathi ngesikhathi sokukhiqiza kungathinta okuqukethwe komswakama kokugcina.
Ukomisa ngokushesha kungabangela umswakama osele, kanti ukomisa kancane kungabangela umswakama owengeziwe ukuthi ugcinwe.
Ibanga le-HPMC:
Amazinga ahlukene e-HPMC (isb., i-viscosity ephansi, i-viscosity ephakathi, noma i-viscosity ephezulu) angaba nokuqukethwe komswakama okuhlukahluka kancane ngenxa yokwehluka kwesakhiwo sama-molecule kanye nokucutshungulwa kwawo.
Imininingwane Yomhlinzeki:
Abahlinzeki banganikeza i-HPMC okuqukethwe komswakama okuqondile okuhambisana nezindinganiso zezimboni.
Okuqukethwe Okujwayelekile Komswakama we-HPMC Ngokwebanga
Okuqukethwe komswakama we-HPMC kuyahlukahluka kuye ngebanga kanye nokusetshenziswa okuhlosiwe. Nansi ithebula elibonisa amazinga omswakama ajwayelekile ebanga elihlukene le-HPMC.
| Ibanga le-HPMC | Ukuthamba (cP) | Okuqukethwe komswakama (%) | Izicelo |
| Ukujiya Okuphansi kwe-HPMC | 5 – 50 | 7 – 10 | Imithi (amaphilisi, ama-capsule), izimonyo |
| Ukuthamba Okuphakathi HPMC | 100 – 400 | 8 – 10 | Imithi (ukukhishwa okulawulwayo), ukudla, izinamathiselo |
| I-HPMC Enobungqabavu Obuphezulu | 500 – 2000 | 8 – 12 | Ukwakha (okusekelwe kusimende), ukudla (i-ejenti yokujiya) |
| I-HPMC Yezokwelapha | 100 – 4000 | 7 – 9 | Amaphilisi, izembozo ze-capsule, ukwakheka kwejeli |
| I-HPMC Yezinga Lokudla | 50 – 500 | 7 – 10 | Ukuqina kokudla, ukuhlanganiswa kwe-emuls, ukumbozwa |
| Ibanga Lokwakha i-HPMC | 400 – 10000 | 8 – 12 | Udaka, izinto zokunamathisela, amaplasta, izingxube ezomile |
Ukuhlolwa Nokunqunywa Kokuqukethwe Komswakama
Kunezindlela eziningana ezijwayelekile zokunquma okuqukethwe komswakama we-HPMC. Izindlela ezimbili ezivame kakhulu yilezi:
Indlela Yokulinganisa I-Gravimetric (Ukulahlekelwa Kokomisa, I-LOD):
Lena yindlela esetshenziswa kakhulu yokunquma okuqukethwe umswakama. Isisindo esaziwayo se-HPMC sifakwa kuhhavini owomisayo obekwe ku-105°C. Ngemva kwesikhathi esithile (ngokuvamile amahora angu-2-4), isampula iyakalwa futhi. Umehluko wesisindo unikeza okuqukethwe umswakama, okuvezwa njengephesenti lesisindo sesampula sokuqala.
UKarl Fischer Uhlu Lwezikhundla:
Le ndlela inembe kakhulu kune-LOD futhi ihilela ukusabela kwamakhemikhali okulinganisa okuqukethwe kwamanzi. Le ndlela ivame ukusetshenziswa lapho kudingeka ukunqunywa komswakama okunembile.
Umthelela Wokuqukethwe Komswakama Ezimpahleni ze-HPMC
Umswakama we-AnxinCel®HPMC uthinta ukusebenza kwayo ezinhlotsheni ezahlukene zokusebenza:
Ukujiya:Ubuningi bomswakama bungathinta ukujiya kwezixazululo ze-HPMC. Ubuningi bomswakama bungandisa ukujiya kwezinye izindlela zokwenza izinto, kanti ubuningi bomswakama obuphansi bungaholela ekujiya okuphansi.
Ukuncibilika:Umswakama owedlulele ungaholela ekuhlanganiseni noma ekunciphiseni ukuncibilika kwe-HPMC emanzini, okwenza ingasebenzi kahle kwezinye izinhlelo zokusebenza, njengezindlela zokukhulula ezilawulwayo embonini yezemithi.
Ukuzinza:I-HPMC ngokuvamile izinzile ezimweni ezomile, kodwa okuqukethwe umswakama ophezulu kungabangela ukukhula kwamagciwane noma ukuwohloka kwamakhemikhali. Ngenxa yalesi sizathu, i-HPMC ivame ukugcinwa ezitsheni ezivaliwe ezindaweni ezinomswakama ophansi.
Okuqukethwe komswakama kanye nokupakishwa kwe-HPMC
Ngenxa yemvelo ye-HPMC e-hygroscopic, ukupakisha okufanele kubalulekile ukuvimbela ukumuncwa komswakama emoyeni. I-HPMC ivame ukupakisha ezikhwameni noma ezitsheni ezingangeni umswakama ezenziwe ngezinto ezifana ne-polyethylene noma ama-laminate anezingqimba eziningi ukuze ivikeleke emswakama. Ukupakisha kuqinisekisa ukuthi okuqukethwe komswakama kuhlala ngaphakathi kobubanzi obufunekayo ngesikhathi sokugcina nokuthuthwa.
Ukulawulwa Kokuqukethwe Komswakama Emkhakheni Wokukhiqiza
Ngesikhathi sokukhiqizwa kwe-HPMC, kubalulekile ukuqapha nokulawula okuqukethwe komswakama ukuze kulondolozwe ikhwalithi yomkhiqizo. Lokhu kungafezwa ngokusebenzisa:
Izindlela Zokomisa:I-HPMC ingomiswa kusetshenziswa umoya oshisayo, ukomisa nge-vacuum, noma imishini yokomisa ejikelezayo. Izinga lokushisa kanye nobude bokomisa kumele kulungiselelwe ukuze kugwenywe ukomisa okungaphelele (umswakama omningi) kanye nokomisa ngokweqile (okungaholela ekuwohlokeni kokushisa).
Ukulawulwa Kwemvelo:Ukugcina indawo elawulwayo enomswakama ophansi endaweni yokukhiqiza kubalulekile. Lokhu kungabandakanya ama-dehumidifier, i-air conditioner, kanye nokusetshenziswa kwezinzwa zomswakama ukuqapha izimo zomkhathi ngesikhathi sokucubungula.
Umswakama wokuqukethwe I-HPMCngokuvamile kuwela ngaphakathi kwebanga eliphakathi kuka-7% kuya ku-10%, yize kungahluka kuye ngebanga, ukusetshenziswa, kanye nezimo zokugcina. Okuqukethwe komswakama kuyipharamitha ebalulekile ethinta izakhiwo ze-rheological, ukuncibilika, kanye nokuqina kwe-AnxinCel®HPMC. Abakhiqizi kanye nabakhiqizi kudingeka balawule ngokucophelela futhi baqaphe okuqukethwe komswakama ukuqinisekisa ukusebenza kahle kakhulu ekusetshenzisweni kwabo okuthile.
