I-Hydroxypropyl Methylcellulose (HPMC yesikhashana) iyi-polymer ephezulu yokwenza i-moleculatic esetshenziswa kakhulu emikhiqizweni yempilo yezimboni neyonsuku zonke. Ensimini yama-detegents, i-HPMC iye yaqala ukuba isengezo esisemqoka ngokusekelwe ekusebenzeni kwayo okuhle.
1. Izici eziyisisekelo ze-HPMC
I-HPMC iyi-ether engeyona eye-moulsose eyenziwe nge-cellulose yemvelo ngokuguqulwa kwamakhemikhali. Inezimpawu ezilandelayo ezilandelayo:
I-Solubinity yamanzi: I-HPMC ingancibilika emanzini abandayo namanzi ashisayo ukwakha obala isixazululo se-viscous.
Ukuqina: Kuzinzile ku-Acidic noma i-Alkaliiried Media, akunangqondo ekushintsheni kokushisa, futhi kunokumelana nokushisa nokuhanjiswa kweqhwa.
Ukuqina: I-HPMC inomphumela omuhle wokuqina, ingakhulisa ngempumelelo ukubonwa kohlelo loketshezi, futhi akulula ukuwahlukanisa.
Ukukhamulwa ifilimu: I-HPMC ingakha ifilimu efanayo ebusweni ukuhlinzeka ngokuvikelwa kanye nemiphumela yokuhlukaniswa.
Yilezi zici ezenza ukusetshenziswa kwe-HPMC ku-detegents zinamandla amakhulu nenani.
2. Iqhaza le-HPMC kuma-detegents
Ezihlalweni, imisebenzi esemqoka ye-HPMC ifaka phakathi ukuqina, ukuqina, ukumiswa, kanye nokwakheka kwefilimu. Imisebenzi ethize imi kanjena:
Kukhulu
Ama-detegents ngokuvamile adinga ukulondolozela ukubonwa okuthile ukuze athuthukise isipiliyoni somsebenzisi. I-HPMC ingakha isakhiwo esizinzile se-colloidal ngokuhlanganisa namanzi ukukhulisa ukubonwa kwesihlanzi. Okwezinhlanzi eziwuketshezi, ukubonakala okufanele kungavimba ukugeleza okwedlulele, okwenza umkhiqizo ube lula ukulawula nokusabalalisa lapho kusetshenziswa. Ngaphezu kwalokho, ukuqina kungasiza ekuthuthukiseni ukuthinta kokuhlanza, okwenza kube bushelelezi lapho kufakwa noma kuthululwe, kanye nokufaka okuhlangenwe nakho okunethezekile.
Isitabili
Ukuhlanza uketshezi kuvame ukuqukatha ama-surfactants, amakha, imibala nezinye izithako. Ngesikhathi sokugcina isikhathi eside, lezi zithako zingashukunyiswa noma zibole. I-HPMC ingasetshenziswa njenge-stabilizer ukuvimbela ukwenzeka kwe-stratication. Kwakha isakhiwo senethiwekhi eyunifomu, kukhambisa futhi kusabalalisa ngokulinganayo izithako ezahlukahlukene, futhi kugcina ukufana nokuqina kwesikhathi eside kwesiteleka.
Umenzeli osamile
Ezinye izinhlayiya eziqinile (njengezinhlayiya ezi-abrasive noma izithako ezithile zokuqashwa) zivame ukungezwa ku-detegents yanamuhla. Ukuze uvikele lezi zinhlayiya kusuka ekuxazululeni noma ekuhlanganiseni uketshezi, i-HPMC njenge-ejenti yokumisa okwesikhashana ingamisa ngempumelelo izinhlayiya eziqinile ku-liquid medium ukuqinisekisa ukuhanjiswa okufanayo kwezinhlayiya ngesikhathi sokusetshenziswa. Lokhu kungathuthukisa amandla okuhlanza wonke umkhiqizo futhi kuqinisekise ukuthi kungasebenza njalo lapho kusetshenziswa njalo.
Umenzeli okha amafilimu
Izakhiwo ezenziwe ngefilimu ze-HPMC zenza zihluke kokuhlanza okukhethekile. Isibonelo, kwezinye izinto ezithambile zendwangu noma okokugeza izitsha, i-hpmc ingakha ifilimu evikelayo ebusweni ngemuva kokuhlanza, ukuthuthukisa ubucwebe bobuso bento ngenkathi kunciphisa izinsalela zamabala noma amabala amanzi. Le filimu nayo ingasebenza njengehlukaniso lokuvimbela ubuso bento ekuxhumaneni ngokweqile nemvelo yangaphandle, ngaleyo ndlela yandisa ukuqina komphumela wokuhlanza.
I-moisturizer
Eminye imikhiqizo yokuwasha, ikakhulukazi insipho yensipho noma imikhiqizo yokugeza etholakala ngqo nesikhumba, i-HPMC inomphumela wokuswakama. Kungasiza ukunciphisa ukulahleka kwamanzi ngesikhathi senqubo yokuwasha, ngaleyo ndlela kugwemeke isikhumba esomile. Ngaphezu kwalokho, ingaletha umphumela ovikelayo wokuvikela, okwenza isikhumba sithambile futhi sibusheleleke.
3. Ukusetshenziswa kwe-HPMC ngezinhlobo ezahlukene zokuhlanza
Okokuhlanza uketshezi
I-HPMC isetshenziswa kabanzi kuma-detegegents awuketshezi, ikakhulukazi emikhiqizweni efana nokuhlanza izingubo nokuhlanza izitsha zokugeza. Ingalungisa i-viscosity yama-detegents futhi ithuthukise ukungafani kanye nesipiliyoni sokusetshenziswa kwemikhiqizo. Ngaphezu kwalokho, i-HPMC iyancibilika ngokumangazayo emanzini futhi ayithinti umphumela wokuhlanza wezinto zokuhlanza.
Ama-sanitizers ezandla nama-gels okugeza
I-HPMC ibuye ibe khona njengomuntu omkhulu kanye nomswakama emikhiqizweni yokunakekelwa komuntu siqu efana nama-sanitizer wezandla nama-gels okugeza. Ngokwengeza i-viscosity yomkhiqizo, okokuhlanza akulula ukuhambisa izandla, kuthuthukise ukuzizwa kwayo. Ngaphezu kwalokho, i-HPMC inganciphisa ukucasuka esikhunjeni futhi ivikele isikhumba ngomonakalo yindawo yangaphandle.
Ukuwasha i-powder kanye nokuhlanza okuqinile
Yize i-HPMC ingasetshenziswa kangako ezihlanzisweni eziqinile, isengadlala indima yokulwa nokwenziwa kwe-casing kanye nokuqina kokushintshwa kwamafomula athile athile wokuwasha. Kungavimbela i-powder kusuka ku-agglomerating futhi uqinisekise ukungafani kwayo okuhle lapho kusetshenziswa.
Okokuhlanza umsebenzi okhethekile
Kwezinye izinsimbi ezinemisebenzi ekhethekile, enjengezinto ezibonakalayo ezifana ne-antibacterial detegergents, okokuhlanza kwama-phosphate-free, njll., HPMC, njengengxenye yefomula ehlanganisiwe, kungathuthukisa inani elingeziwe lale mikhiqizo. Kungasebenza nezinye izithako ezisebenzayo ukuthuthukisa umphumela nokuqina komkhiqizo.
4. Ukuthuthukiswa kwesikhathi esizayo kwe-HPMC emkhakheni wezinto zokuhlanza
Njengoba izimfuno zabathengi zokuvikela imvelo kanye nokwanda kwezempilo, ukwakhiwa kwezinsimbi kukhula kancane kancane endaweni eluhlaza okotshani kanye nemvelo. Njengezinto ezibonakalayo ezinobungane bemvelo ezisuselwa ku-cellulose yemvelo, i-HPMC iyi-biodegradable futhi ngeke ibe umthwalo wemvelo. Ngakho-ke, ekuthuthukisweni kwesikhathi esizayo kwama-detegents, i-HPMC kulindeleke ukuthi yandise ezinye izindawo zayo zohlelo lokusebenza.
Ngokuthuthuka kobuchwepheshe bokuhlanza, ukwakheka kwamangqamuzana kwe-HPMC kungabuye kwenziwe kahle futhi kuguqulwe ukuthuthukisa imikhiqizo esebenza kabanzi. Isibonelo, ngokwenza ngcono ukuvumelana nezimo zayo zokushisa noma i-PH, i-HPMC ingagcina ukusebenza kwayo okuhle ngaphansi kwezimo ezengeziwe.
I-HPMC isibe ngenye yezithasiselo ezibalulekile emkhakheni wezinto zokuhlanza ngenxa yezakhiwo zayo ezinhle kakhulu nangamakhemikhali ezifana nokuqina, ukuzinza, ukwakheka kwamafilimu, kanye nokumiswa. Akugcini nje ngokuthuthukisa isipiliyoni sokusetshenziswa kwezinto zokuhlanza, kepha futhi kunikeza imikhiqizo ukuqina okunamandla nokusebenza. Ngokuzayo, ngokuthuthuka kwesayensi nobuchwepheshe, amathemba wesicelo se-HPMC ezihlalweni azobanzi, futhi kuzoletha izixazululo ezintsha kakhulu embonini.
