Yiziphi izinzuzo ze-hydroxypropyllls?

I-Hydroxypropylllulose (HPC) i-cellulose ye-celtule ye-celtule ye-cellulose yamanzi esetshenziswa kabanzi kwezokwelapha, ukudla, izimonyo kanye nezinye izinkambu.

1. Ukuqina okuhle
I-HPC iyi-polymer engeyona eye-ioocomlity enhle. Lokhu kwenza kube yinto evame ukusetshenziswa i-excipient emkhakheni wezemithi, ikakhulukazi kumalungiselelo omlomo kanye namalungiselelo we-ophthalmic. Ingasetshenziswa njenge-binder, ifilimu langaphambili, i-matrix elawulwa ukukhishwa, njll. Ngaphezu kwalokho, i-HPC isetshenziswa futhi njengesikhundla kanye ne-stabilizer embonini yokudla ngaphandle kokuthinta ukunambitheka nokuphepha kokudla.

2. I-solubility yamanzi amahle nokuchithwa
I-HPC ingachithwa kuwo womabili lamanzi abandayo nawashisayo, okwenza kube nohlu olubanzi lwamandla wesicelo ezixazululweni ezahlukahlukene. I-solubenity yayo axhomezeki emazingeni okushisa kuphela, kodwa futhi nangezinga lawo lokufaka esikhundleni. I-HPC ngesixazululo ingakha isixazululo se-colloidal esobala ngokuqina okuhle. Le mpahla yenza ukuthi isetshenziswe kabanzi kwizimonyo kanye nemikhiqizo yokunakekelwa komuntu siqu, njengokuqina kanye nefilimu yangaphambili e-lotion, okhilimu kanye namajeli.

3. Izakhiwo ezinhle kakhulu zefilimu
I-HPC inezakhiwo ezinhle ezenziwe ngefilimu futhi ingakha amafilimu asobala futhi aqinile. Le mpahla yenza kube ngomunye wezinto ezibalulekile zokuthola izidakamizwa. Isendlalelo sefilimu ye-HPC ehlanganisiwe ebusweni bethebhulethi ngeke nje ithuthukise ukubukeka nokunambitheka kwesidakamizwa, kepha futhi ilawula ukuqina kwesidakamizwa, yenza ngcono ukuqina kwesidakamizwa, thuthukisa ukuqina komuthi. Ngaphezu kwalokho, ekupakisheni kokudla, izakhiwo ezakha amafilimu ze-HPC nazo zisetshenziselwa ukwenza amafilimu adliwayo nezimbobo, ngaleyo ndlela anwebe impilo yeshelufu yokudla.

4. I-Thermoplasticity nezakhiwo zemishini
I-HPC ikhombisa i-thermoplasticity enhle, okusho ukuthi ingabunjwa ibe yibumo obuhlukahlukene lapho kufudunyezwa futhi kugcina isimo sayo ngemuva kokupholisa. Le mpahla ikunikeza inzuzo eyingqayizivele ekuphrintweni kwe-3D kanye neminye imisebenzi yokucubungula. Ngaphezu kwalokho, izakhiwo zemishini ze-HPC ziphakeme kakhulu. Inokuguquguquka okuhle nokuqina, okunganciphisa ngempumelelo isizukulwane sezingcezu ngesikhathi sethebhulethi ngokucindezela futhi uthuthukise ikhwalithi yamathebulethi.

5. Ukuqina nokuqina kwamakhemikhali
I-HPC inokuqina okuhle ebangeni elibanzi le-PH futhi alithinteki kalula ngama-acids nase-alkalis. Ngaphezu kwalokho, inokumelana ne-oxidation enhle nokumelana nokukhanya, futhi kukhombisa ukuzinza okuhle ngaphansi kwezimo ezahlukahlukene zezemvelo. Lokhu bekuvumela ukuthi kugcinwe imisebenzi yayo nemiphumela emisebenzini ehlukahlukene, ikakhulukazi kumalungiselelo emithi kanye nezimonyo, ezingathuthukisa impilo yeshalofu kanye nokusebenzisa umphumela womkhiqizo.

6. Ukuvuselelwa okuguquguqukayo
I-viscosity ye-HPC ingalawulwa ngokulungisa isisindo sayo samangqamuzana kanye nesilinganiso sokufakwa esikhundleni. Lokhu kuvumela ukuthi kunikeze izakhiwo ezifanele ze-Rheological kuzicelo ezihlukile. Isibonelo, emalungiseleleni amakhamithi, ama-viscosities ahlukene we-HPC angasetshenziswa ukulungisa isilinganiso sokukhishwa kanye nezinga lokufakwa kwezidakamizwa; Ezimonyo, i-HPC ene-visosities ehlukene ingahle isetshenziselwe ukwenza imikhiqizo enezinto ezahlukahlukene, njenge-lotion, ama-gels kanye nokhilimu.

7. Ukuvikelwa Kwezemvelo kanye ne-biodegradatability
I-HPC isuselwa ku-cellulose yemvelo, ngakho-ke ine-biodegradeality enhle nokuvikelwa kwemvelo. Ngokwesimo samanje sezidingo eziphakeme ngokwengeziwe zokuvikelwa kwemvelo, lesi sici se-HPC sibaluleke kakhulu. Akunakunciphisa ukungcoliswa kwemvelo kuphela, kepha futhi kudilizwa ama-microorganisms, kunciphisa umthelela wesikhathi eside ku-ecosystem.

Njengezinto ezisebenza ngemisebenzi, i-Hydroxypropylllulose inamathemba okusebenza abanzi nezinzuzo. I-Biocomtic yayo enhle, i-soubelity yamanzi, izakhiwo ezakha amafilimu, izakhiwo zemishini nokuqina kwenza kube nendima ebalulekile emikhakheni eminingi efana nemithi, ukudla nezimonyo. Ngasikhathi sinye, i-viscosity eguqukayo kanye nobungani bezemvelo be-HPC buthuthukisa inani layo lesicelo. Ngokuthuthukiswa kwesayensi nobuchwepheshe kanye nezinguquko ekufuneni kwemakethe, ubukhulu bokuthi buhle nemisebenzi ye-HPC izoqhubeka nokwanda.
