Eyaziwa nangokuthi i-hypromellose, iyi-ether engeyona i-ionic cellulose esebenza ngezindlela eziningi futhi esetshenziswa kabanzi ethathwe kuma-polymers emvelo afana nokotini ocolisisiwe noma i-pulp yokhuni ngochungechunge lwezinqubo zamakhemikhali.I-HPMC iyi-methyl cellulose ether derivatives polymer futhi ikhona njengempushana emhlophe engenaphunga, engenabuthi, nenganambitheki.Ingancibilika emanzini ashisayo nabandayo ukuze yakhe isixazululo se-viscous esisobala esinezinhlobonhlobo zezakhiwo ezenza kube efiselekayo kakhulu ukusetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza.I-HPMC inokujiya okuhle kakhulu, ukubopha, ukusabalalisa, ukufaka i-emulsifying, ukwenza ifilimu, ukumisa okwesikhashana, i-adsorbing, i-gelling, i-surface-active, ukugcinwa kwamanzi, nokuvikela izakhiwo ze-colloid.Isetshenziswa kakhulu ezimbonini ezahlukene ezifana nezokwakha, ezemithi, ukudla, i-PVC, izitsha zobumba, kanye nemikhiqizo yokunakekelwa komuntu siqu/yasekhaya.Embonini yezokwakha, i-HPMC ivamise ukusetshenziswa njenge-thickener yodaka lwemiksi eyomile, okunamathelisa amathayela, opende abasuselwe emanzini, i-wall putty, uchungechunge lwe-thermal insulation mortar.Ngaphezu kwalokho, isetshenziswa njengesithako sezemithi nesithako sokudla, kanye nasekukhiqizeni i-PVC, izinto zobumba, nezinto zokuhlanza.Izindwangu, imikhiqizo yokunakekelwa komuntu siqu, nemikhiqizo yokunakekela ekhaya ngokuvamile iqukethe i-HPMC njengesithako.
Izinhlobo ze-Hydroxypropyl Methylcellulose
IHydroxypropyl Methylcellulose Isetshenziselwa Yini?
I-HPMC itholakala emithonjeni yemvelo efana nokotini nokhuni.Inqubo ihilela ukuqinisa i-cellulose ukuze uyithole, bese wengeza i-propylene oxide ne-methyl chloride ukuze i-etherification, okuholela ekukhiqizweni kwe-cellulose ether.
I-HPMC iyi-ether ye-cellulose enemisebenzi eminingi esetshenziswa ezimbonini eziningi njenge-thickener, stabilizer, ne-binder, phakathi kokunye.Ukusetshenziswa kwayo okusabalele kufaka phakathi ukwakhiwa, ukwenza imithi, izitsha zobumba, nokudla, phakathi kokunye.
I-IbangCell® HPMC iyisengezo esisebenziseka ngezindlela eziningi futhi esivumelana nemvelo, sinikeza izinzuzo eziningi ezifana nokusetshenziswa okubanzi, ukusetshenziswa okuncane ngeyunithi ngayinye, ukuguqulwa okuphumelelayo, nokusebenza komkhiqizo okuthuthukisiwe.Ukwengezwa kwayo kuthuthukisa ukusebenza kahle kokusetshenziswa kwezinsiza kanye nenani lemikhiqizo.Kuyisithasiselo esihambelana nemvelo ezimbonini ezahlukahlukene.
1. I-excipient yezemithi:
IHydroxypropyl Methylcellulose (HPMC) iyisithako esibalulekile kwezemithi, evumela ukukhishwa kwezidakamizwa okuqhubekayo futhi okulawulwayo, okokugcotshwa kwamaphilisi, ama-agent alengayo, ama-tablet binder, nama-disintegrants ngamafomu ahlukene okulethwa kwezidakamizwa, njengamaphilisi emifino.Ukuguquguquka kwayo kanye nobubanzi bokusetshenziswa kwayo okubanzi kuyenza isizakale kakhulu embonini yezemithi, ithuthukisa ukusebenza kwezidakamizwa, kanye nokwenza ngcono ulwazi lwesiguli.Ukwengeza, i-HPMC inobungani nemvelo, iyasimama, futhi iyonga imali, okuyenza ibe yisinqumo esihle sokuthuthukisa imikhiqizo yezemithi.
2. Isithako Sokudla
IHydroxypropyl Methylcellulose (HPMC) iyisengezo sokudla esiphephile nesiguquguqukayo esisetshenziswa emhlabeni wonke njengesithako esijiyayo, esiqinisayo, nesithambisayo ukuze kuthuthukiswe ukunambitheka nokuthungwa.Ithola ukusetshenziswa okubanzi kwezinto ezibhakwayo, amasoso, ukhilimu ophehliwe, amajusi wezithelo, inyama, kanye nemikhiqizo yamaprotheni.I-HPMC yamukelwa kabanzi futhi igunyazwe ukusetshenziswa kokudla emazweni amaningi, okuhlanganisa i-United States, China, kanye ne-European Union.Sekukonke, i-HPMC idlala indima ebalulekile empumelelweni yemboni yezokudla ngokunika amandla impilo yeshelufu ethuthukisiwe, ukunambitheka, nokukhanga kwabathengi kwemikhiqizo ehlukahlukene yokudla kuyilapho igcina amazinga aphezulu okuphepha.
Lesi sigaba sidingida isimo samanje eShayina mayelana nokusetshenziswa kweHydroxypropyl Methylcellulose (HPMC) ekukhiqizeni ukudla.Njengamanje, ingxenye ye-HPMC yebanga lokudla esetshenziswa embonini yokudla yaseShayina iphansi kakhulu ngenxa yentengo ephezulu kanye nokusetshenziswa okulinganiselwe.Kodwa-ke, ngokukhula okuqhubekayo kwemboni yokudla ngokuhamba kwesikhathi kanye nokuqwashisa okwandayo kokudla okunempilo, izinga lokungena kwe-HPMC njengesengezo sezempilo kulindeleke ukuthi likhuphuke kancane kancane.Ukusetshenziswa kwe-HPMC kungathuthukisa imikhiqizo ehlukene ngokuthuthukisa ukuzinza, ukuthungwa, kanye nempilo yeshelufu.Ngakho-ke, kulindeleke ukuthi ukusetshenziswa kwe-HPMC embonini yokudla kuzokhula ngokuzayo.Lokhu kungaholela ekwandeni kokuqamba okusha kanye nentuthuko embonini yokudla ukuze ihambisane nokushintsha okuthandwa ngabathengi kanye nesidingo semikhiqizo yokudla enempilo, ephezulu.
3. Udaka lwe-drymix yokwakha
Lesi sigaba sichaza ukusetshenziswa okuhlukahlukene kwe-Hydroxypropyl Methylcellulose (HPMC) embonini yodaka lwe-dry-mix mortar.I-HPMC isetshenziswa kabanzi njenge-ejenti egcina amanzi kanye ne-retarder, eyenza udaka luhlale lusebenza futhi lumpompa isikhathi eside.Iphinde isebenze njengesibophezelo, ithuthukise ukusabalala, futhi yandise isikhathi sokusebenza sezinto zokwakha njenge-plaster, i-putty powder, neminye imikhiqizo efanayo.I-HPMC iphinde ibe usizo ekunamathiseleni ithayela, imabula, nomhlobiso wepulasitiki, inikeze ukuqiniswa nokunciphisa inani likasimende elidingekayo kule nqubo.Ngezindawo ezinhle kakhulu zokugcina amanzi, i-HPMC ithuthukisa amandla engxube ngemuva kokuqina futhi ivimbele udaka ekuqhekekeni ngenxa yokoma ngokushesha ngemuva kokufakwa.Sekukonke, i-HPMC iyisithako esibalulekile embonini yezokwakha esifeza izidingo ezahlukahlukene, njengokuthuthukisa ukusebenza nokuthuthukisa izakhiwo zomkhiqizo wokugcina.
Ungayisebenzisa Kanjani I-Hydroxypropyl Methylcellulose?
Indlela Yokuqala
Ngenxa yokuhambisana kwe-HPMC, ingaxutshwa kalula nezinto ezihlukahlukene eziyimpuphu ezifana nosimende, i-talc yamatshe, nezingulube ukuze kuzuzwe ukusebenza okufunayo.
1. Isinyathelo sokuqala sokusebenzisa i-HPMC ukuyixuba nazo zonke ezinye izithako ize yome ngokuphelele ixutshwe.Lokhu kusho ukuthi i-HPMC kufanele ixutshwe kanye nezinye izinto eziyimpuphu (ezifana nosimende, impushana yegypsum, ubumba lwe-ceramic, njll.) ngaphambi kokwengeza noma imaphi amanzi.
2. Esinyathelweni sesibili, inani elifanele lamanzi lengezwa engxubeni, futhi lixutshwe futhi lixutshwe kuze kube yilapho umkhiqizo ohlanganisiwe uqedwa ngokuphelele.Lesi sinyathelo siqinisekisa ukuthi ingxube iba ukunamathisela okufanayo okungasetshenziswa kalula endaweni oyifunayo.
Indlela Yesibili
1.Isinyathelo sokuqala sihlanganisa ukwengeza inani elithile lamanzi abilayo esitsheni esinyakazisiwe esinokucindezeleka okukhulu kwe-shear.Lokhu kusiza ukudiliza izinhlayiya ze-HPMC futhi kuqinisekiswe ukuthi zihlakazeke ngokulinganayo emanzini.
2.Esinyathelweni sesibili, ukunyakazisa kufanele kuvulwe ngesivinini esiphansi, futhi umkhiqizo we-HPMC kufanele uhlungwe kancane kancane esitsheni esinyakazayo.Lokhu kusiza ukuvimbela izigaxa ukuthi zingakheki futhi kuqinisekisa ukuthi i-HPMC isatshalaliswa ngokulinganayo ngaphakathi kwesixazululo.
3.Isinyathelo sesithathu sibandakanya ukuqhubeka nokunyakazisa kuze kube yilapho zonke izinhlayiya zomkhiqizo we-HPMC sezicwile emanzini.Le nqubo iqinisekisa ukuthi izinhlayiya ze-HPMC zimanziswe ngokugcwele futhi zilungele ukuncibilika.
4.Esinyathelweni sesine, umkhiqizo we-HPMC ushiywe umele ukupholisa kwemvelo ukuze uhlakazeke ngokuphelele.Ngemuva kwalokho, isisombululo se-HPMC siyanyakaziswa ngokuphelele ngaphambi kokusetshenziswa.Kubalulekile ukuqaphela ukuthi i-ejenti ye-antifungal kufanele yengezwe etshwaleni likamama ngokushesha ngangokunokwenzeka.
5.Esinyathelweni sesihlanu, umkhiqizo we-HPMC uhlungwa kancane esitsheni sokuxuba.Kubalulekile ukugwema ukwengeza inani elikhulu lomkhiqizo we-HPMC owakhe izigaxa ngqo esitsheni sokuxuba.
6.Ekugcineni, esinyathelweni sesithupha, ezinye izithako kufomula zengezwa ukuqedela ukulungiswa komkhiqizo ophelile.
