(1). Isingeniso esiyisisekelo
I-HPMC (i-Hydroxypropyl Methyl Cellulose, i-hydroxypropyl methylcellulose) iyi-cellulose ether engeyona i-ionic esetshenziswa kabanzi embonini yamakhemikhali yansuku zonke, ikakhulukazi emikhiqizweni yokunakekelwa komuntu siqu.
(2). Izici
1. Incibilika ngokushesha emanzini abandayo
I-HPMC yamakhemikhali yansuku zonke inokuncibilika kwamanzi abandayo okuhle kakhulu, okwenza kube lula futhi kusebenze kahle ngesikhathi sokusetshenziswa. Ama-ether e-cellulose endabuko adinga ukushisa noma ukuxuba isikhathi eside lapho encibilika, kuyilapho i-HPMC esheshayo yamanzi abandayo ingancibilika ngokushesha ekamelweni lokushisa ukuze yakhe isixazululo esifanayo nesizinzile, esifinyeza kakhulu isikhathi sokukhiqiza kanye nobunzima benqubo.
2. Izakhiwo ezinhle kakhulu zokuqina nokumiswa
Njengesithako esiqinile sekhwalithi ephezulu, i-HPMC ingakhulisa kakhulu ukujiya kwemikhiqizo ewuketshezi ngamanani aphansi, ithuthukise ukuthungwa kanye nolwazi lokusetshenziswa komkhiqizo. Ngaphezu kwalokho, ingamisa futhi izinzise izinhlayiya eziqinile ngempumelelo, ivimbele ukubola, futhi iqinisekise ukuhambisana nokuqina komkhiqizo.
3. Izakhiwo ezinhle zokwakha amafilimu
I-HPMC inezakhiwo ezinhle zokwakha ifilimu futhi ingakha ifilimu yokuvikela eguquguqukayo, ephefumulayo ebusweni besikhumba. Lesi sici siyenza isetshenziswe kabanzi emikhiqizweni yokunakekelwa kwesikhumba ukusiza ukuvala umswakama nokunikeza imiphumela yokuthambisa ehlala isikhathi eside ngenkathi kuthuthukiswa ukushelela kwesikhumba kanye nokuthamba.
4. Ukucaca okuphezulu
Isixazululo se-HPMC esincibilikisiwe sinokukhanya okuphezulu, okubalulekile emikhiqizweni eminingi yamakhemikhali yansuku zonke edinga ukugcina ukubukeka okukhanyayo noma okukhanyayo. Isibonelo, emikhiqizweni efana nesihlanzi sezandla esibonakalayo, imaski yobuso esobala kanye nejeli ekhanyayo, ukusetshenziswa kwe-HPMC kungagcina ukubukeka kwayo okuhle.
5. Ukuqina kwamakhemikhali kanye nokuhambisana kwezinto eziphilayo
I-HPMC inezakhiwo zamakhemikhali ezizinzile, ayithambekeli ekuphenduleni kwamakhemikhali noma ekuwohlokeni, futhi ihlala izinzile emazingeni ahlukahlukene e-pH kanye namazinga okushisa. Ngesikhathi esifanayo, ihambisana kahle futhi ngeke ibangele ukucasuka noma ukusabela kokungezwani komzimba esikhumbeni. Ifanele ukusetshenziswa ezinhlotsheni ezahlukene zesikhumba, ikakhulukazi isikhumba esibucayi.
6. Imiphumela yokufumisa nokugcoba
I-HPMC inomphumela omuhle kakhulu wokuthambisa futhi ingakha ungqimba lokuthambisa ebusweni besikhumba ukuze inciphise ukulahleka kwamanzi. Ngesikhathi esifanayo, futhi inomphumela wokugcoba, okwandisa ukushelela kanye nokulula kokusebenzisa umkhiqizo, okwenza umuzwa wokusebenzisa ukhululeke kakhudlwana.
(3). Izinzuzo
1. Thuthukisa ikhwalithi yomkhiqizo kanye nolwazi lomsebenzisi
I-HPMC yamanzi abandayo asheshayo esezingeni lamakhemikhali nsuku zonke ingathuthukisa kakhulu ukuthungwa, ukuzinza kanye nokubukeka kwemikhiqizo, ngaleyo ndlela ithuthukise ikhwalithi yomkhiqizo kanye nokuhlangenwe nakho komsebenzisi. Izakhiwo zayo zokuqina, ukwakha ifilimu kanye nokuthambisa zenza imikhiqizo yamakhemikhali yansuku zonke incintisane kakhulu emakethe.
2. Yenza lula inqubo yokukhiqiza futhi unciphise izindleko
Ngenxa yokuncibilika kwayo ngokushesha emanzini abandayo, ukusetshenziswa kwe-HPMC kungenza inqubo yokukhiqiza ibe lula futhi kunciphise isidingo sokushisa nokuxuba isikhathi eside, ngaleyo ndlela kuncishiswe ukusetshenziswa kwamandla kanye nezindleko zokukhiqiza. Ngaphezu kwalokho, ukuncibilika okusheshayo kanye nokusatshalaliswa okufanayo nakho kuthuthukisa ukusebenza kahle kokukhiqiza.
3. Ukuguquguquka kanye nokusetshenziswa okubanzi
Ukuguquguquka kwe-HPMC kwenza isetshenziswe kabanzi embonini yamakhemikhali yansuku zonke. Ingatholakala emikhiqizweni ehlukahlukene kusukela emikhiqizweni yokunakekelwa kwesikhumba, ama-shampoo, ama-shower gels kuya ezihlanzini, izinsipho, njll. Imisebenzi yayo eminingi ingahlangabezana nezidingo zemikhiqizo ehlukene futhi inikeze ukuguquguquka okwengeziwe ekwakhiweni kokwakheka komkhiqizo.
4. Ukuphepha nokuvikelwa kwemvelo
Njenge-cellulose derivative etholakala ngokwemvelo, i-HPMC inokubola okuhle kanye nobungane nemvelo. Ngesikhathi senqubo yokukhiqiza nokusebenzisa, akukho zinto eziyingozi ezizokhiqizwa, futhi ayinangozi emvelweni nasempilweni yabantu, futhi ihlangabezana nezidingo zomphakathi wanamuhla zemikhiqizo eluhlaza neyobungani nemvelo.
5. Ukunikezwa okuzinzile kanye nekhwalithi elawulekayo
Ngenxa yobuchwepheshe bokukhiqiza obuvuthiwe be-HPMC, ukuhlinzekwa kwemakethe okuzinzile kanye nekhwalithi elawulekayo, ingaqinisekisa ukuqhubeka nokuvumelana kokukhiqizwa kwemikhiqizo yamakhemikhali yansuku zonke. Izindinganiso zayo zekhwalithi kanye nemingcele yokusebenza kungenziwa ngezifiso ngokwezidingo zamakhasimende ukuze kuhlangatshezwane nezidingo ezithile zezimakethe ezahlukene kanye nezicelo.
I-cellulose esheshayo yamanzi abandayo yansuku zonke yezinga lamakhemikhali i-HPMC idlala indima ebalulekile embonini yamakhemikhali yansuku zonke ngezakhiwo zayo ezihlukile zomzimba nezamakhemikhali kanye nokusebenza kwayo okuningi. Ukuncibilika kwayo okusheshayo emanzini abandayo, izakhiwo ezinhle kakhulu zokujiya nokumisa, imiphumela emihle yokwakha ifilimu nokuthambisa, kanye nezici zokuphepha nokuvikela imvelo kuyenza ibe yisithasiselo esifanele emikhiqizweni eminingi yamakhemikhali yansuku zonke. Ngokuthuthukisa ikhwalithi yomkhiqizo, ukwenza lula izinqubo zokukhiqiza kanye nokunciphisa izindleko, i-HPMC ayihlangabezani nje nesidingo semakethe, kodwa futhi iletha inani lebhizinisi elanele emabhizinisini. Ngokuthuthuka kwesayensi nobuchwepheshe kanye nokujula kokusetshenziswa kwayo, amathemba e-HPMC emkhakheni wamakhemikhali wansuku zonke azoba banzi.
