IHydroxypropyl Methylcellulose (i-HPMC ngamafuphi) iyi-semi-synthetic high molecular polymer esetshenziswa kabanzi emikhiqizweni eyahlukene yezimboni neyokuphila kwansuku zonke. Emkhakheni wezihlanzi, i-HPMC kancane kancane isiye yaba isithako esibalulekile ngokusekelwe ekusebenzeni kwayo okuhle kakhulu.
1. Izakhiwo eziyisisekelo ze-HPMC
I-HPMC iyi-ether engeyona ionic cellulose eyenziwe nge-cellulose yemvelo ngokuguqulwa kwamakhemikhali. Inezici ezilandelayo ezibalulekile:
Ukunyibilika kwamanzi: I-HPMC ingancibilika emanzini abandayo nasemanzini ashisayo ukuze yakhe isixazululo se-viscous esingafihli.
Ukuzinza: Iqinile uma kuqhathaniswa kumithombo ye-asidi noma ye-alkaline, ayizwani nokushintsha kwezinga lokushisa, futhi inokumelana nokushisa nokumelana nokuncibilika.
Ukuqina: I-HPMC inomphumela omuhle wokujiya, ingakhuphula ngempumelelo i-viscosity yesistimu ye-liquid, futhi akulula ukujiya.
Ukwenza ifilimu: I-HPMC ingenza ifilimu efanayo phezulu ukuze inikeze ukuvikeleka kanye nemiphumela yokuhlukaniswa.
Yilezi zici ezenza ukusetshenziswa kwe-HPMC kwezihlanzi kube namandla kanye nenani elikhulu.
2. Iqhaza le-HPMC ezintweni zokuhlanza
Ezihlahleni, imisebenzi esemqoka ye-HPMC ihlanganisa ukujiya, ukuqiniswa, ukumiswa, nokwakheka kwefilimu. Imisebenzi ethize imi kanje:
I-Thickener
Izihlanzi ngokuvamile zidinga ukugcina i-viscosity ethile ukuze kuthuthukiswe ulwazi lomsebenzisi. I-HPMC ingakha isakhiwo se-colloidal esizinzile ngokuhlanganisa namanzi ukuze kwandiswe i-viscosity ye-detergent. Okokuhlanza okuwuketshezi, i-viscosity efanele ingavimbela ukugeleza ngokweqile, okwenza umkhiqizo ube lula ukuwulawula nokusabalalisa lapho usetshenziswa. Ngaphezu kwalokho, ukujiya kungasiza futhi ukuthuthukisa ukuthinta okokuhlanza, kukwenze kube bushelelezi uma usetshenziswa noma uthululwa, futhi ulethe umuzwa wokusebenzisa ngokunethezeka.
Isiqinisi
Izihlanzi eziwuketshezi zivame ukuqukatha ama-surfactants, amakha, ama-pigments nezinye izithako. Ngesikhathi sokugcina isikhathi eside, lezi zithako zingase zihlukaniswe noma zibole. I-HPMC ingasetshenziswa njengesiqinisi ukuvimbela ukwenzeka kwe-stratification. Yakha isakhiwo senethiwekhi esifanayo, ihlanganisa futhi isakaze ngokulinganayo izithako ezihlukahlukene, futhi igcine ukufana nokuzinza kwesikhathi eside kwe-detergent.
Umenzeli omisiwe
Ezinye izinhlayiya eziqinile (njengezinhlayiya eziqhumayo noma ezinye izithako zokuqeda ukungcola) zivame ukungezwa ezintweni zokuhlanza zesimanje. Ukuze uvimbele lezi zinhlayiya ukuthi zingahlali noma zihlangane oketshezini, i-HPMC njenge-ejenti yokumisa ingamisa ngokuphumelelayo izinhlayiya eziqinile endaweni yoketshezi ukuze kuqinisekiswe ukusatshalaliswa okufanayo kwezinhlayiya ngesikhathi sokusetshenziswa. Lokhu kungathuthukisa ikhono lokuhlanza lonke lomkhiqizo futhi kuqinisekise ukuthi ungasebenza ngokungaguquki isikhathi ngasinye lapho usetshenziswa.
I-ejenti yokwenza ifilimu
Izakhiwo zefilimu ze-HPMC ziyenza ihluke kwezinye izihlanzi ezikhethekile. Isibonelo, kwezinye izithambisa zendwangu noma okokuhlanza umshini wokuwasha izitsha, i-HPMC ingenza ifilimu evikelayo ngaphezulu ngemva kokuhlanza, ithuthukise ukucwebezela kwendawo ngenkathi yehlisa insalela yamabala noma amabala amanzi. Le filimu ingase futhi isebenze njengokuzihlukanisa ukuvimbela ubuso bento ekuxhumaneni ngokweqile nemvelo yangaphandle, ngaleyo ndlela yandise ukuqina komphumela wokuhlanza.
I-Moisturizer
Kweminye imikhiqizo yokuwasha, ikakhulukazi insipho yezandla noma imikhiqizo yokugeza ethintana ngqo nesikhumba, i-HPMC inomphumela wokuswakama. Kungasiza ukunciphisa ukulahlekelwa kwamanzi ngesikhathi sokugeza, ngaleyo ndlela kugweme isikhumba esomile. Ngaphezu kwalokho, kungaletha nomphumela omnene wokuvikela, okwenza isikhumba sibe mnene futhi sibushelelezi.
3. Ukusetshenziswa kwe-HPMC ezinhlotsheni ezahlukene zokuhlanza
Iziwashi eziwuketshezi
I-HPMC isetshenziswa kakhulu ezintweni zokuhlanza eziwuketshezi, ikakhulukazi emikhiqizweni efana nezihlanzi zokuwasha kanye nezihlanzi zokuwasha izitsha. Ingakwazi ukulungisa i-viscosity yezihlanzi futhi ithuthukise ukuhlakazeka nomuzwa wokusetshenziswa kwemikhiqizo. Ngaphezu kwalokho, i-HPMC incibilika ngokuzinza emanzini futhi ayithinti umphumela wokuhlanza izinto zokuhlanza.
Ama-sanitizer esandla namajeli okugeza
I-HPMC futhi ikhona njenge-thiener kanye ne-moisturizer emikhiqizweni yokunakekelwa komuntu siqu njengama-sanitizer esandla namajeli eshawa. Ngokwandisa i-viscosity yomkhiqizo, i-detergent akulula ukuyisusa ezandleni, ithuthukise umuzwa wayo wokusetshenziswa. Ngaphezu kwalokho, i-HPMC inganciphisa ukucasuka esikhumbeni futhi ivikele isikhumba ekulimaleni kwendawo yangaphandle.
Impushana yokuwasha nezihlanzi eziqinile
Nakuba i-HPMC ingasetshenziswa kancane ezintweni zokuhlanza eziqinile, isengadlala indima emelene ne-caking kanye nokuqinisa ukuzinza kwamanye amafomula athile empushana yokuwasha. Ingavimbela impushana ukuthi ingahlangani futhi iqinisekise ukuhlakazeka kwayo okuhle lapho isetshenziswa.
Iziwashi ezisebenza ngokukhethekile
Kwezinye izihlanzi ezinemisebenzi ekhethekile, njengezihlanzi ezilwa namagciwane, izihlanzi ezingena-phosphate, njll., i-HPMC, njengengxenye yefomula eyinhlanganisela, ingathuthukisa inani elengeziwe lale mikhiqizo. Ingasebenza nezinye izithako ezisebenzayo ukuze kuthuthukiswe umphumela nokuzinza komkhiqizo.
4. Ukuthuthukiswa kwesikhathi esizayo kwe-HPMC emkhakheni wezokuhlanza
Njengoba izimfuno zabathengi zokuvikelwa kwemvelo kanye nempilo zikhula, ukwakhiwa kwezihlanzi kukhula kancane kancane ngendlela eluhlaza nengokwemvelo. Njengento evumelana nemvelo etholakala ku-cellulose yemvelo, i-HPMC iyakwazi ukubola futhi ngeke ithwalise imvelo. Ngakho-ke, ekuthuthukisweni kwesikhathi esizayo kwezihlanzi, i-HPMC kulindeleke ukuthi iqhubeke yandise izindawo zayo zokufaka isicelo.
Ngokuthuthuka kobuchwepheshe bokuhlanza, ukwakheka kwamangqamuzana e-HPMC kungathuthukiswa futhi kulungiswe ukuze kuthuthukiswe imikhiqizo esebenza kakhulu. Isibonelo, ngokuthuthukisa ukujwayela kwayo kumazinga okushisa noma i-pH, i-HPMC ingagcina ukusebenza kwayo okuhle kakhulu ngaphansi kwezimo ezimbi kakhulu.
I-HPMC isibe esinye sezithasiselo ezibalulekile emkhakheni wezokuhlanza ngenxa yezakhiwo zayo ezinhle kakhulu zomzimba namakhemikhali njengokujiya, ukuqiniswa, ukwakheka kwefilimu, nokumiswa. Akuthuthukisi nje kuphela ulwazi lokusebenzisa okokuhlanza, kodwa futhi kunikeza imikhiqizo ukuzinza nokusebenza okuqinile. Ngokuzayo, ngokuthuthuka kwesayensi nobuchwepheshe, amathuba okusetshenziswa kwe-HPMC ezintweni zokuhlanza azoba banzi, futhi azoletha izixazululo ezintsha embonini.
