I-Hydroxypropyl methylcellulose (HPMC)Ingabe ikhemikhali le-polymer lemvelo elisetshenziswe kabanzi ezimbonini eziningi ezinjengezokwakha, ezemithi, izimonyo kanye nokudla. Kungumkhiqizo owenziwe kusuka ku-cellulose ngokusebenzisa ukuguqulwa kwamakhemikhali ukuguqulwa, futhi ikakhulukazi kukhombisa i-solubity yamanzi aphezulu, izakhiwo ezinhle zefilimu, i-emulsation, kanye nezakhiwo ezibalulekile, ngakho-ke inenani elibalulekile ezincelweni ezahlukahlukene zezimboni nezentengiso.
1. Ukwakheka kanye nezakhiwo
I-HPMC itholakala ngokulungiswa kokuguqulwa kwezinyathelo ezimbili zama-molecule we-cellulose. Okokuqala, iqembu le-methyl liyethulwa ngokusabela kwe-methylation ukuthola i-methyl cellulose (MC). Ngemuva kwalokho, i-hydroxypropylylylyly itholakala ngokuphendula iqembu le-hydroxyl ku-molecule ye-cellulose nge-hydroxyl gerow ku-cellulose molecule. Isakhiwo saso samangqamuzana siqukethe amaqembu amabili e-hydrophilic, i-hydroxypropyl ne-methyl, enikeza i-kimacell®hpmc enhle nokuqina okuhle nokuqina.
Kukhambi, i-HPMC ibonisa amandla amahle e-solubility nama-colloidal, futhi ingakha isixazululo se-viscous. I-solubelity yayo ithintekile ngezinga lokufaka esikhundleni se-hydroxypropyl kanye ne-methyl ku-molecule kanye nesisindo samangqamuzana. Iziqu ezahlukahlukene zokufaka iziqu kanye nezinsimbi zamangqamuzana zingashintsha i-solubity kanye nokubonakala kwe-HPMC ukuze sihlangabezane nezidingo zohlelo lokusebenza ezihlukile.
2. Izici eziyinhloko
2.1 Ukuqina
I-HPMC inomphumela oqinile wokuqina futhi ingakhulisa kakhulu ukubonakala kwesixazululo. I-HPMC isetshenziswa kabanzi njengomuntu omkhulu ezimbonini ezinjengokwakha, ukumboza kanye nezimonyo. Akunakuthuthukisa ukungaguquguquki komkhiqizo, kepha futhi kuthuthukisa i-Rheology kanye nokusebenza kohlelo lokusebenza komkhiqizo.
2.2 Izakhiwo ezenziwe ngefilimu
Ifilimu eyakhiwa yi-Kimacell®HPMC kwisixazululo samanzi namanzi anamanzi nokuvumelana nezimo, futhi isetshenziswa kabanzi kwimikhiqizo efana nemithi efana nemithi, izimonyo kanye nokugqoka. Isibonelo, emalungiseleleni amakhamithi, i-HPMC ivame ukusetshenziswa njenge-ejenti yokukhishwa elawulwayo ukulawula isilinganiso sokukhishwa kwezidakamizwa; Ezimonyo, kuvame ukusetshenziselwa ukwakha ifilimu ukuze kuthuthukiswe umphumela wokupholisa kwesikhumba.
2.3 I-Solubity
I-HPMC ihlakaze kahle emanzini abandayo futhi ihlakaze ngokushesha. I-solubility yayo izinzile ngamanani ahlukile we-PH, okwenza kusebenze kahle ngaphansi kwezimo ezahlukahlukene.
2.4 emulsation kanye nokuhlakazeka
I-HPMC ingasebenza njenge-emulsifier ukusiza izigaba ezahlukahlukene zezinto zixube kangcono. Ukufakelwa kwalo kwenza kube ngumthwali wemikhiqizo efana nemibala nezidakamizwa, ezisiza ukuthuthukisa ukuqina kanye nokufana kwemikhiqizo.
2.5 Ukuvikelwa Kwezemvelo nokuphepha
Njengesitshalo semvelo se-cellulose depuletive, i-HPMC ine-biodegrade enhle, ayinangozi imvelo, iphephile futhi ayinobuthi, futhi ihlangabeze izidingo zokukhiqizwa kwesimanje kwemvelo. Ngakho-ke, i-HPMPC isetshenziswa kabanzi emikhiqizweni yabathengi engenangozi nenemvelo, ikakhulukazi ezimbonini zokudla, ezenza imithi kanye nezimonyo.
3. Izindawo zohlelo lokusebenza
3.1 Imboni Yokwakha
Embonini yezokwakha, i-HPMC ivame ukusetshenziswa njengesengezo ngodaka kasimende. Kungathuthukisa ukusebenza kodaka, kuthuthukise ukunamathela kodaka, futhi kwandise isikhathi sayo esivulekile, okwenza ukwakhiwa kube lula kakhulu. Ngaphezu kwalokho, i-HPMC ingathuthukisa futhi ukumelana nokuqhekeka nokumelana kwamanzi ngodaka.
3.2 Imboni Yezemithi
Embonini yezemithi, i-KimaCell®HPMC isetshenziswa ikakhulukazi njenge-ejenti yokukhishwa kwezidakamizwa, i-emulsifier kanye ne-ejenti eyakha amafilimu yama-caplule. Ngenxa yokubhekelwa kwayo okuhle kanye ne-biodegradeability, i-HPMC isetshenziswa kabanzi lapho kulungiswa izidakamizwa ezikhipha okuqhubekayo, ezingalawula ngempumelelo isilinganiso sokukhishwa kwezidakamizwa futhi sandise ukusebenza kwezidakamizwa.
3.3 imboni yokudla
I-HPMC, njengesengezo sokudla, imvamisa isetshenziswa ku-ayisikhilimu, ama-khekhe, iziphuzo zejusi neminye imikhiqizo, ikakhulukazi ukuqina, ukuqina nokuqina kanye nokuqinisekiswa. Kungakhuphula ukunambitheka kanye nokuthungwa kokudla nokunweba impilo yaseshalofini.
3.4 imboni yezimonyo
I-HPMC isetshenziswa kabanzi ensimini yezimonyo, ikakhulukazi e-lotion, okhilimu, ama-shampoos kanye neminye imikhiqizo. Akugcini nje ngokudlala indima ekukhulekeni naseku-emulsation, kepha futhi ihlinzeka ngemiphumela emihle yokunakekelwa kwesikhumba, njengokuthambisa kanye nokulwa no-oxidation.
3.5 amakhemikhali nsuku zonke
Kumakhemikhali wansuku zonke, i-HPMC ivame ukusetshenziswa njenge-nyouner, emulsifier ne-stabilizer, futhi isetshenziswa kabanzi ku-detegents, ama-shampoos, ama-gels okugeza neminye imikhiqizo. Kungathuthukisa ukuqina komkhiqizo futhi kugcinwe isakhiwo esifanayo ngaphansi kwezimo ezihlukile.
4. Izinzuzo zezobuchwepheshe kanye nezitayela zentuthuko
Izinzuzo zobuchwepheshe zeKimacell®HPMC zilele ekusebenzeni kwayo okuhle kanye nezinhlelo zokusebenza ezihlukene. Akugcini nje ngokuba nezinto eziguquguqukayo zomzimba, kepha futhi kungasebenza ngokuxhumana ngezinto ezahlukahlukene zokuthuthukisa ikhwalithi nokusebenza komkhiqizo wokugcina. Ngokwephuculwa kokuqwashisa ngokuvikelwa kwemvelo kanye nokwanda kwesidingo sabantu semikhiqizo ephephile, engeyona into engenabungozi, amathemba wesicelo se-HPMC abanzi kakhulu.
Ngokuthuthuka kweI-HPMCUbuchwepheshe bokukhiqiza kanye nokuthuthukiswa okuqhubekayo kobuchwepheshe bokuguqulwa, uhlelo lwayo ezimbonini ezahlukahlukene luzokhulisa kakhulu, ikakhulukazi emkhakheni wokuvikelwa kwemvelo nezinto zokuvikela ze-bioderhadable. Ngasikhathi sinye, ukusebenza kwe-HPMC kuzothuthukiswa ukuhlinzeka ngezixazululo ezisebenza kahle ukuze kuhlangatshezwane nezidingo zemakethe ezihluke kakhulu.
I-Hydroxypropylylylylyl vele yaba yinto ebalulekile eyisisekelo kuzo zonke izigaba zempilo ngenxa yokuqina kwayo okuhle, ukwakha ifilimu, ukufezekisa, ukuvikelwa kwemvelo, ukuphepha kanye nokuvikelwa kwemvelo. Ngokuthuthukiswa kwesayensi nobuchwepheshe kanye nezinguquko ezidingweni zezimboni, insimu yesicelo se-HPMC izokwanda futhi, iletha amathuba amaningi amasha namathuba wentuthuko.
