IHydroxypropyl Methylcellulose (HPMC)yi-polymer compound enyibilikayo emanzini efunyanwa ngokuguqula i-cellulose yendalo ngokweekhemikhali. Isetyenziswa kakhulu kwicandelo lamayeza, ukutya, izinto zokuthambisa, kunye nokwakha, kwaye ineempawu ezintle kakhulu ezifana nokuqina, ukwenza ifilimu, ukuxuba, kunye nozinzo.
1. Umgaqo wokulungiselela
I-Hydroxypropyl methylcellulose yi-hydrophilic cellulose derivative, kwaye ukunyibilika kwayo kuchaphazeleka kakhulu yi-hydroxypropyl kunye ne-methyl substituents kwi-molecule. Iqela le-methyl liyandisa ukunyibilika kwamanzi, ngelixa iqela le-hydroxypropyl linyusa izinga lokunyibilika kwamanzi. Ngokubanzi, i-AnxinCel®HPMC inokunyibilika ngokukhawuleza emanzini abandayo ukuze yenze isisombululo esifanayo se-colloidal, kodwa inyibilika kancinci emanzini ashushu, kwaye izinto ezinamaqhekeza zinobunzima bokuhlangana ngexesha lokunyibilika. Ke ngoko, kufuneka kunikwe ingqalelo ekulawuleni ubushushu bokunyibilika kunye nenkqubo yokunyibilika ngexesha lokulungiselela.
2. Ukulungiswa kwezinto eziluhlaza
Umgubo we-HPMC: Khetha umgubo we-HPMC one-viscosities ezahlukeneyo kunye namanqanaba okutshintshwa ngokweemfuno zokusetyenziswa. Iimodeli eziqhelekileyo ziquka i-viscosity ephantsi (ubunzima obuphantsi be-molecular) kunye ne-viscosity ephezulu (ubunzima obukhulu be-molecular). Ukhetho kufuneka lusekelwe kwiimfuno zefomyula ethile.
Isinyibilikisi: Amanzi sesona sinyibilikisi sisetyenziswa kakhulu, ingakumbi xa kusetyenziswa amayeza nokutya. Ngokweemfuno zokunyibilikisa, umxube wamanzi kunye nezinyibilikisi eziphilayo, ezifana nesinyibilikisi esixutyiweyo se-ethanol/water, nawo ungasetyenziswa.
3. Indlela yokulungiselela
Ukulinganisa i-HPMC
Okokuqala, linganisa ngokuchanekileyo umgubo we-HPMC ofunekayo ngokwengxinano yesisombululo esiza kulungiswa. Ngokubanzi, uluhlu loxinzelelo lwe-HPMC luphakathi kwe-0.5% ukuya kwi-10%, kodwa uxinano oluthile kufuneka luhlengahlengiswe ngokwenjongo kunye ne-viscosity efunekayo.
Ukunyibilika ngaphambi kokumanzisa
Ukuze kuthintelwe ukuba umgubo we-HPMC ungadibani, kudla ngokusetyenziswa ukunyibilika ngaphambi kokuba umanziswe. Umsebenzi othile ngowokuba: fafaza umgubo we-HPMC olinganisiweyo ngokulinganayo kwinxalenye yesinyibilikisi, uxube kancinci, uze wenze umgubo we-HPMC udibane nesixa esincinci sesinyibilikisi kuqala ukuze wenze imeko yokumanzisa. Oku kunokuthintela ngempumelelo umgubo we-HPMC ekudibaniseni kwaye kukhuthaze ukusasazeka kwawo okufanayo.
Inkqubo yokuchithwa
Yongeza kancinci isinyibilikisi esiseleyo kumgubo we-HPMC omanzi uze uqhubeke uvuselela. Ekubeni i-HPMC inokunyibilika kakuhle kwamanzi, amanzi kunye ne-HPMC ziyanyibilika ngokukhawuleza kubushushu begumbi. Kuphephe ukusebenzisa amandla aphezulu kakhulu xa uvuselela, kuba uvuselela ngamandla kuya kubangela ukuba kwenziwe amaqamza, okuchaphazela ukucaca kunye nokufana kwesisombululo. Ngokubanzi, isantya sokuvuselela kufuneka sigcinwe kumgama ophantsi ukuqinisekisa ukunyibilika okufanayo.
Ulawulo lobushushu
Nangona i-HPMC inokunyibilika emanzini abandayo, ukuba izinga lokunyibilika licotha, isisombululo singafudunyezwa ngokufanelekileyo. Ubushushu bokufudumeza kufuneka bulawulwe phakathi kwama-40°C nama-50°C ukuze kuthintelwe amaqondo obushushu aphezulu kakhulu abangela utshintsho kwisakhiwo se-molecular okanye utshintsho olubukhali kwi-viscosity yesisombululo. Ngexesha lenkqubo yokufudumeza, kufuneka kuqhutyekwe nokuxutywa de i-HPMC inyibilike ngokupheleleyo.
Ukupholisa kunye nokucoca
Emva kokunyibilika ngokupheleleyo, vumela isisombululo siphole ngokwendalo ukuya kubushushu begumbi. Ngexesha lenkqubo yokupholisa, inani elincinci lamaqamza okanye ukungcola kunokuvela kwisisombululo. Ukuba kuyimfuneko, isihluzo singasetyenziselwa ukusihluza ukususa amasuntswana aqinileyo anokubakho kunye nokuqinisekisa ukucaca nokucaca kwesisombululo.
Uhlengahlengiso lokugqibela kunye nokugcinwa
Emva kokuba isisombululo sipholisiwe, uxinzelelo lwaso lunokulungiswa ngokweemfuno zokwenyani. Ukuba uxinzelelo luphezulu kakhulu, kunokongezwa isinyibilikisi ukuze sinyibilike; ukuba uxinzelelo luphantsi kakhulu, kufuneka kongezwe umgubo omninzi we-HPMC. Emva kokuba isisombululo silungisiwe, kufuneka sisetyenziswe ngoko nangoko. Ukuba kufuneka sigcinwe ixesha elide, kufuneka sigcinwe kwisikhongozeli esivaliweyo ukuze kuthintelwe ukufuma kwamanzi okanye ukungcola kwesisombululo.
4. Amanyathelo okuzikhusela
Ulawulo lobushushu: Ubushushu obuphezulu kufuneka buphetshwe ngexesha lokunyibilika ukuze kuthintelwe ukuguquguquka nokusebenza kwe-AnxinCel®HPMC. Kubushushu obuphezulu, i-HPMC inokwehla okanye i-viscosity yayo inciphe, nto leyo echaphazela impembelelo yokusetyenziswa kwayo.
Indlela yokuxukuxa: Kuphephe ukucheba kakhulu okanye isantya esiphezulu sokuxukuxa ngexesha lokuxukuxa, kuba ukuxukuxa okunamandla kunokubangela ukuba kubekho amaqamza kwaye kuchaphazele ukucaca kwesicombululo.
Ukukhetha isinyibilikisi: Amanzi sesona sinyibilikisi sisetyenziswa kakhulu, kodwa kwezinye iindlela ezikhethekileyo, isisombululo esixutyiweyo samanzi kunye nezinye izinyibilikisi (ezifana notywala, i-acetone, njl.njl.) sinokukhethwa. Umlinganiselo owahlukileyo we-solvent uya kuchaphazela izinga lokunyibilika kunye nokusebenza kwesisombululo.
Iimeko zokugcina: Isisombululo se-HPMC esilungisiweyo kufuneka sigcinwe kwindawo epholileyo neyomileyo ukuze kuthintelwe ukuvezwa ixesha elide kubushushu obuphezulu okanye elangeni ngqo ukuthintela utshintsho kumgangatho wesisombululo.
Ukungagayi: Xa umgubo wongezwa kwisinyibilikisi, ukuba umgubo wongezwa ngokukhawuleza okanye ngokungalinganiyo, kulula ukwenza amaqhuma, ngoko ke kufuneka wongezwe kancinci kancinci.
5. Amasimi esicelo
I-Hydroxypropyl methylcellulose isetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yokunyibilika kwayo kakuhle emanzini kunye nokuhambelana kwayo nezinto eziphilayo:
Ishishini lezonyango: Njengesixhobo sokulungisa amachiza, esinamathelayo, esiqinisayo, esikhupha ulwelo rhoqo, njl. njl., sidlala indima ebalulekileyo kwinkqubo yokulungiselela amachiza.
Ishishini lokutya: Njengesithambisi-mveliso, isithambisi-mveliso, isiqinisi-mveliso, isetyenziswa rhoqo ekucubunguleni ukutya, njenge-ayisikhrim, izinongo, iziselo, njl.
Ishishini lokwakha: Njengesithambisi sokwakha kunye nodaka, sinokuphucula ukunamathelana kunye nokugeleza komxube.
Izithambiso: Njengesithambisi-mafutha, isiqinisi kunye nesithambisi-mafutha, isetyenziswa kwizithambiso ezifana neekhrimu, iishampu, kunye neemveliso zokhathalelo lolusu ukuphucula umgangatho wemveliso kunye namava omsebenzisi.
Ukulungiswa kweI-HPMCyinkqubo efuna ingqalelo kwiinkcukacha. Ngexesha lenkqubo yokulungiselela, izinto ezifana nobushushu, indlela yokuxukuxa, kunye nokukhetha isinyibilikisi kufuneka zilawulwe ukuqinisekisa ukuba sinokunyibilika ngokupheleleyo kwaye kugcinwe ukusebenza kakuhle. Ngendlela yokulungiselela echanekileyo, i-AnxinCel®HPMC ingasetyenziswa kakhulu kumashishini amaninzi kwaye idlala indima yayo ebalulekileyo.
