IHydroxypropylmethylcellulose (HPMC) iyi-polymer eguquguqukayo futhi eguquguqukayo esetshenziswa ezinhlobonhlobo zezimboni.Le nhlanganisela ingeyomndeni we-cellulose ether futhi itholakala ku-cellulose yemvelo.I-HPMC ikhiqizwa ngokushintsha i-cellulose ngokusabela kwamakhemikhali, okuholela ku-polymer encibilika emanzini enezici eziyingqayizivele.Ukusetshenziswa kwayo okusabalele kungenxa yokuguquguquka kwayo, i-biocompatibility, kanye nekhono lokuhlanganisa izakhiwo zayo nezinhlelo zokusebenza ezithile.
1. Imboni yezemithi:
A. Ukwakhiwa kwethebhulethi:
I-HPMC iyisithako esibalulekile ekwenziweni kwemithi, ikakhulukazi ekukhiqizweni kwamathebulethi.Isebenza njengesibophezelo ukusiza ukuhlanganisa izithako zethebhulethi.Ngaphezu kwalokho, i-HPMC ilawule izakhiwo zokukhululwa, iqinisekisa ukukhululwa kancane kancane kwezithako zemithi esebenzayo (ama-API) emzimbeni.Lokhu kubalulekile emithini edinga ukukhululwa okuqhubekayo nokulawulwayo ukuze kube nomphumela ophelele wokwelapha.
b.I-coating yefilimu encane:
I-HPMC isetshenziswa kakhulu embonini yezemithi yamaphilisi anefilimu.Amafilimu e-HPMC athuthukisa ukubukeka kwamaphilisi, imaski ukunambitheka kwezidakamizwa kanye nephunga, futhi ahlinzeke ngokuvikeleka ezicini zemvelo.Ukukhishwa kwezidakamizwa ezilawulwayo nakho kungafinyelelwa ngokusebenzisa ukwakheka okukhethekile kwe-coating yefilimu.
C. Izixazululo ze-Ophthalmic:
Ekwakhekeni kwamehlo, i-HPMC isetshenziswa njengesilungisi se-viscosity kanye nesigcobo.I-biocompatibility yayo iyenza ifanelekele ukusetshenziswa kumaconsi wamehlo, ithuthukise ukunethezeka kwamehlo futhi ithuthukise ukusebenza kahle kokwelapha kwezithako ezisebenzayo.
d.Amalungiselelo angaphandle:
I-HPMC isetshenziswa ezinhlobonhlobo zamalungiselelo asematheni afana nokhilimu namajeli.Isebenza njenge-thickener, ithuthukisa i-viscosity yomkhiqizo futhi inikeze ukuthungwa okubushelelezi, okufiselekayo.Ukuncibilika kwayo emanzini kuqinisekisa ukusetshenziswa okulula nokumuncwa esikhumbeni.
e.Ukumiswa kanye ne-emulsions:
I-HPMC isetshenziselwa ukuzinzisa ukumiswa kanye nama-emulsions kumafomu omthamo we-liquid.Ivimbela izinhlayiya ekuzinzeni futhi iqinisekise ngisho nokusatshalaliswa komuthi kulo lonke ukwakhiwa.
2. Imboni yezokwakha:
A. Izinamatheliso zamathayela kanye neGrout:
I-HPMC ivamise ukusetshenziswa kuzinto zokunamathisela amathayela nama-grouts ngenxa yezakhiwo zayo zokugcina amanzi.Ithuthukisa ukusebenza kahle, inwebe isikhathi esivulekile, futhi ithuthukise ukunamathela kokunamathela kumatayela nama-substrates.Ukwengeza, i-HPMC isiza ukuthuthukisa amandla esewonke kanye nokuqina kwe-adhesive.
b.Udaka lukasimende:
Emasimende osimende, i-HPMC isebenza njenge-ejenti egcina amanzi futhi ithuthukisa ukusebenza kwengxube.Iphinde isize ekunamatheleni nasekuhlanganeni kodaka, iqinisekise isibopho esingaguquki nesiqinile phakathi kwezindawo ezingaphezulu.
C. Izinhlanganisela zokuzilinganisa:
I-HPMC iyisithako esibalulekile kuzinhlanganisela zokuzilinganisa ezisetshenziswa ezinhlelweni zokubeka phansi.Inikeza izakhiwo zokugeleza ku-compound, ivumela ukuthi isakaze ngokulinganayo futhi izimele, okuholela ekubeni bushelelezi, ngisho nendawo.
d.Imikhiqizo esekwe ku-Gypsum:
I-HPMC isetshenziswa ekukhiqizweni kwemikhiqizo esekwe ku-gypsum njengenhlanganisela ehlangene kanye ne-stucco.Ithuthukisa ukungaguquguquki nokusebenza kwale mikhiqizo, inikeze ukunamathela okungcono futhi inciphise ukuwohloka.
3. Imboni yokudla:
A. Ukwakheka nokuzwakala komlomo:
Embonini yokudla, i-HPMC isetshenziswa njenge-thickener kanye ne-ejenti ye-gelling.Kuyasiza ukufeza ukuthungwa okufunayo kanye nokuzwakala emlonyeni ekudleni okuhlukahlukene, okuhlanganisa amasoso, ama-dessert nemikhiqizo yobisi.
b.Ukushintshwa kwamafutha:
I-HPMC ingasetshenziswa esikhundleni samafutha ekwakhiweni okuthile kokudla ukusiza ukunciphisa okuqukethwe kwekhalori kuyilapho kugcinwa ukuthungwa okufiswayo nezimfanelo zezinzwa.
C. I-Emulsification kanye nokuzinza:
I-HPMC isetshenziselwa emulsification kanye nokuqiniswa kwemikhiqizo yokudla, efana nama-condiments kanye nemayonnaise.Isiza ukwakha ama-emulsion azinzile, ivimbela ukuhlukaniswa kwesigaba futhi yandise impilo yeshalofu.
d.Ingilazi kanye nama-coatings:
I-HPMC isetshenziswa emikhiqizweni ecwebezelayo kanye nezingubo zokugqoka.Inikeza ukubukeka okubushelelezi nokucwebezelayo, kuthuthukisa ukunamathela, futhi kusiza ukuthuthukisa ikhwalithi yonke yomkhiqizo oqediwe.
4. Imboni yezimonyo:
A. I-Rheology Modifier:
I-HPMC isetshenziswa njengesilungisi se-rheology ekwakhiweni kwezimonyo, esithinta i-viscosity nokuthungwa kokhilimu, okokugcoba kanye namajeli.Inikeza umkhiqizo umuzwa obushelelezi, wokunethezeka.
b.I-Emulsion stabilizer:
Kuma-emulsions ezimonyo, njengamakhilimu nama-lotions, i-HPMC isebenza njengesiqinisi, ivimbela izigaba zamanzi nezamafutha ukuthi zingahlukani.Lokhu kusiza ukuthuthukisa ukuzinza kanye nempilo yeshelufu yomkhiqizo.
C. Ifilimu yangaphambili:
I-HPMC isetshenziswa njenge-ejenti eyenza ifilimu kuzimonyo ezifana ne-mascara nesifutho sezinwele.Yakha ifilimu eguquguqukayo esikhumbeni noma ezinweleni, inikeza izinzuzo ezihlala isikhathi eside nokuningi.
d.Umenzeli wokumiswa:
Ekumisweni, i-HPMC ivimbela i-pigments nezinye izinhlayiya eziqinile ukuthi zingahlali, iqinisekise ukusatshalaliswa okulinganayo futhi ithuthukise ukubukeka kwemikhiqizo yezimonyo.
5 Isiphetho:
IHydroxypropyl methylcellulose (HPMC) iyi-polymer esebenza ngezindlela eziningi futhi isetshenziswa ezimbonini ezahlukahlukene, okuhlanganisa ezemithi, ezokwakha, ezokudla nezimonyo.Izici zayo eziyingqayizivele, njengokuncibilika kwamanzi, i-biocompatibility kanye nokuhlukahluka, kuyenza ibe isithako esibalulekile ezinhlobonhlobo zokwakheka.Kungakhathaliseki ukuthi ukuthuthukisa ukusebenza kwamaphilisi emithi, ukuthuthukisa ukusebenza kwezinto zokwakha, ukuthuthukisa ukuthungwa kwemikhiqizo yokudla, noma ukunikeza ukuqina ekwakhiweni kwezimonyo, i-HPMC idlala indima ebalulekile ekuhlangabezaneni nezidingo ezithile zezimboni ezahlukene.Njengoba ucwaningo nobuchwepheshe buqhubeka buthuthuka, ukusetshenziswa nokwakheka kwe-HPMC kungenzeka kwande, kuqinise nakakhulu isikhundla sayo njenge-polymer eguquguqukayo futhi ebaluleke kakhulu kusayensi yezinto ezibonakalayo kanye nokuthuthukiswa komkhiqizo.
