I-Hydroxypropyl methylcellulose (HPMC)Ingabe i-Suritile Cellulose Depulose esetshenziswa kabanzi kwizimboni ezahlukahlukene, kufaka phakathi amakhemikhali, ukudla, kanye nokwakha, ngenxa yezakhiwo zayo ezihlukile ze-physicochemical. Enye yezakhiwo ezibucayi zeCicCencher®HPMC ethuthukisa ukusetshenziswa kwayo ukuhlakazeka kwamanzi okubandayo. Lesi sici sidlala indima ebalulekile ekunqumeni ukusebenza kwayo ezinhlelweni ezahlukahlukene, kusuka ekusungulweni kwemithi kuya kumasimende nama-tile anamathela.
Ukubuka konke kwe-HPMC
I-HPMC iyi-ether ye-onion cellulose etholwa kusuka ku-cellulose yemvelo ngokungenisa ama-hydroxypropyl kanye namaqembu we-methyl. Lokhu kuguqulwa kuphumela ku-polymer okuncibilikayo emanzini futhi kukhombisa indlela yokuziphatha evuthayo. Lapho incibilika, i-HPMC yakha isixazululo esibonakalayo, esibonakalayo, ihlinzeka ngokuqina, ukwakha amafilimu, kanye nokuzinza izakhiwo.
Enye yezimpawu ezibalulekile ze-HPMC yikhono layo lokuhlakazeka emanzini abandayo ngaphandle kwakha izigaxa noma ama-agregates. Le mpahla yenza lula ukuphathwa kwayo kanye nesicelo, okwenza kube yisengezo esihle ezimbonini ezidinga ukuxubeka okunembile nokusebenza kahle.
Izindlela zokuhlakazwa kwamanzi abandayo
Ukuchazwa kwamanzi okubandayo kwe-HPMC kulawulwa ngokuyinhloko yizakhiwo zayo ezingaphandle kanye ne-hydration kinetics. Izindlela ezibalulekile zifaka:
Ukuguqulwa komhlaba: Izinhlayiya ze-HPMC zivame ukuphathwa ngama-ejenti asebenzayo noma izimbobo ze-hydrophilic ukuthuthukisa ukuhlakazwa kwazo. Lokhu kwelashwa kunciphisa ubumbano be-Interpricle, kuvumela izinhlayiya ukuba zihlukanise kalula emanzini.
Ama-Kinetics weHydration: Lapho wethulwa emanzini abandayo, amaqembu we-hpdrophilic ku-HPMC aheha ama-molecule wamanzi. I-hydration elawulwayo iqinisekisa ukusakazwa kancane kancane, ukuvimbela ukwakheka kwama-clumps noma ama-gel mass.
Ukuzwela okushisa: I-HPMC ibonisa iphrofayili ehlukile ye-solubity. Iyancibilika kalula emanzini abandayo kepha yakha ijeli njengoba izinga lokushisa likhuphuka. Le AIDS YOKUZIPHATHA OKUFANELEKILE YOKUZIPHATHA ekusatshalalisweni kwezinhlayiya ngesikhathi sokuhlakazeka kokuqala.
Izici ezithonya ukuhlakazwa kwamanzi okubandayo
Kunezici eziningana zithonya ukuhlakazwa kwamanzi okubandayo kwe-HPMC, kufaka phakathi isakhiwo sayo samangqamuzana, usayizi wezinhlayiyana, kanye nezimo zemvelo:
Isisindo samangqamuzana: Isisindo samangqamuzana seCefinCel®HPMC sinquma ukubonakala kwaso kanye ne-hydration. Amamaki wesisindo aphansi aphansi asakazeka ngokushesha emanzini abandayo, ngenkathi amamaki wesisindo aphezulu angadinga ukufunwa okwengeziwe.
Ukufakwa esikhundleni: izinga le-hydroxypropyl kanye ne-methyl subiniless lithinta i-hydrophicity ye-HPMC. Amazinga aphezulu aphezulu athuthukisa ubuhlobo bamanzi, okwenza ngcono ukuhluka.
Ubukhulu bezinhlayiyana: Ama-powders ahlanganisiwe ama-HPMC asabalalisa kahle ngenxa yendawo yawo engaphezulu. Kodwa-ke, izinhlayiya ezinhle ngokweqile zingase zikhule, zinciphise ukungafani.
Ikhwalithi Yamanzi: Ukuba khona kwama-ion kanye nokungcola kwamanzi kungathonya i-hydration nokuziphatha okuhlukile kwe-HPMC. Amanzi athambile, ama-deionizeen avame ukuthuthukisa ukuhlakazwa.
Imibandela yokuxuba: amasu afanele wokuxuba, njengokungezwa kwe-HPMC ukuze amanzi ashukumisayo ngokuvuselela okuqhubekayo, aqinisekise ukusakazeka okuphezulu futhi anciphise ukuqina.
Izicelo zizuzisa ekuchazeni kwamanzi okubandayo
Amandla we-HPMC ukuhlakazeka emanzini abandayo anemiphumela ebalulekile yokufaka isicelo:
Izemithi: Emakhethini ezidakamizwa, ukusabalalisa kwamanzi okubandayo kuqinisekisa ukuxubeka okufanayo nokuvumelana kokumiswa kokumiswa, ama-gels kanye nokumboza. Le mpahla ibaluleke kakhulu kumathebulethi okukhishwa okulawulwayo, lapho ukusakazwa okuqondile kuthinta amaphrofayli okukhishwa kwezidakamizwa.
Imboni yokudla: Ukuhlakazeka kuka-HPMC kusiza ukusetshenziswa kwayo njengoMkhulu, iStabilizer, kanye ne-Emulsifier emikhiqizweni efana namasobho, amasoso, kanye nama-dessert. Ivumela ukufakwa okulula ngaphandle kokwakheka kwe-lemp, ukuqinisekisa ukwakheka okubushelelezi.
Izinto zokwakha: ezinhlelweni ezenzelwe usimende, ezinjengezinhloso ze-tile kanye nezinhlekelele, ukusabalalisa kwamanzi okubandayo kwe-HPMC kuqinisekisa ukuxubana okungathandeki, ukuthuthukisa ukukhiqizwa, ukunxusa kanye nokugcinwa kwamanzi.
Imikhiqizo yokunakekelwa komuntu siqu: I-HPMC isetshenziswa kuma-shampoos, ama-lotions, kanye nokhilimu ngenxa yokungafani kwayo kanye nezakhiwo ezenziwe ngefilimu. Iqinisekisa ukusatshalaliswa okufanayo kwezithako ezisebenzayo futhi kuthuthukise ukuqina komkhiqizo.
Ukuthuthukisa Ukuchazwa Kwezamanzi Okubandayo
Ukuze uthuthukise ukusabalaliswa kwamanzi okubandayo kwe-HPMC, abakhiqizi baqashe amasu ahlukahlukene:
Ukwelashwa okungaphezulu: Izinhlayiya ze-HPMC ezinama-HPMC ezinama-ejenti asabalalisa noma ukuguqula izakhiwo zazo ezingaphansi komhlaba zinciphisa ukuqina futhi zithuthukisa ukusebenzisana kwamanzi.
I-Granution: Ukuguqula ama-HPMC powders abe ama-granule anciphisa ukwakheka komoya futhi athuthukise ukugeleza nokungafani.
Ukucutshungulwa okwenziwe kahle: Ukulawulwa ngokucophelela kokugaya, ukumiswa kwezinqubo, nezinqubo zokupakisha kuqinisekisa usayizi wezinhlayiyana kanye nomswakama, zombili zinomthelela ophazamisayo.
Ukusetshenziswa kwama-Blends: Ukuhlanganisa i-HPMC namanye ama-polymers ancibilikayo noma izengezo kungavumelanisa nokungafani kwalo kwizicelo ezithile.
Izinselelo Nokulinganiselwa
Naphezu kwezinzuzo zayo, ukusabalalisa kwamanzi okubandayo kweCofiCinchel®hpmc kubandakanya ezinye izinselelo. Amamaki aphezulu okususelwa ekudleni isikhathi eside angadinga izikhathi ezihlala isikhathi eside noma imishini ekhethekile yokuthola ukusakazeka okuphelele. Ngaphezu kwalokho, izici zezemvelo ezifana nobulukhuni bamanzi nokuhlukahluka kokushisa kungathinta ukusebenza kwawo.
Omunye umkhawulo yithuba lokuvuselwa kothuli ngesikhathi sokuphatha, okungabeka izinto zezempilo nezemvelo. Izinqubo zokuphatha okufanele nokusetshenziswa kwamafomu abunjiwe kunganciphisa lezi zinkinga.
Ukuhlakazwa kwamanzi okubandayo kwehydroxypropyl methylcellulosekuyimpahla ebaluleke kakhulu egcizelela ukuguquguquka kwayo kanye nokusetshenziswa kwazo zonke izimboni. Ngokuqonda izindlela nezinto ezithonya ukuhlakazwa, abakhiqizi bangabenza nokwandisa ukwakhiwa kwe-HPMC ukuze bahlangabezane nezidingo ezithile zohlelo lokusebenza. Ukuthuthuka ekuguqulweni komhlaba, amasu we-granulation, kanye nokuhlanganiswa kwe-forting qhubeka ukuthuthukisa ukusebenza nokusebenziseka kwalesi sikhathi esimangazayo se-cellulose. Njengokufunwa kwezinto ezisebenza kahle, ezizinzile, futhi eziphezulu zokusebenza zikhula, indima ye-HPMC njengesengezo esisebenzayo izohlala ibaluleke kakhulu.
