I-Hydroxypropyl cellulose CAS 9004-64-2

1. Insimu yezokwelapha (insimu eyinhloko yokusetshenziswa, kumele ihambisane nezindinganiso zezinga lezokwelapha, njenge-USP, EP, CP)

Izinto ezisizayo zomthamo oqinile womlomo

I-Binder: I-Hydroxypropyl Cellulose HPC isetshenziswa enqubweni yokuhlanganisa amaphilisi nama-capsule (isibonelo, ekuhlanganiseni okumanzi, isixazululo samanzi esingu-1% kuya ku-5% HPC sisetshenziswa njenge-binder ukuthuthukisa ukugeleza nokuqina kwama-granules nokunciphisa ukubambezeleka kokuqhekeka kwamaphilisi).

I-Disintegrant: Izinga eliphansi lokushintsha i-HPC (izinga lokushintsha i-0.2-0.4), ngenxa yokuqukethwe kwayo okuphezulu kwamaqembu e-hydroxyl angashiswanga, inezakhiwo eziqinile zokuvuvukala ngemva kokumunca amanzi futhi ingasetshenziswa njengesithako samaphilisi (umthamo 2% - 5%).

Izinto zokumboza: I-Hydroxypropyl cellulose emathebulethini. Isixazululo se-ethanol se-HPC (5% - 10%) sisetshenziselwa amafilimu ethebhulethi okumboza ukwakha ifilimu evikelayo esobala, efihla ukunambitheka okubabayo komuthi, ithuthukise ukuzinza, futhi ayithinti ukubola.

Izinto zokwakheka kwesikhumba ezikhishwa njalo: I-HPC ene-viscosity ephezulu ingasetshenziswa njenge-skeleton matrix yamaphilisi akhishwa njalo (enesilinganiso esingu-20% kuya ku-50%), futhi izinga lokukhishwa kwesidakamizwa lilawulwa izinga lokuncibilika kwengqimba yejeli ye-HPC, okufeza ukukhishwa okuhlala isikhathi eside amahora angu-12 kuya kwangu-24.

Izinto ezisizayo zesikhumba

I-Hydroxypropyl Cellulose HPC isetshenziswa emaconsini amehlo, amajeli namafutha okugcoba njengesithambisi (ukulungisa i-viscosity yomuthi nokwandisa isikhathi sokuhlala komuthi endaweni yokusebenza) kanye nesiqinisi (ukuvimbela ukuthungwa kwezinhlayiya zemithi).

2. I-Hydroxypropyl cellulose ekudleni (kumele ihambisane nezindinganiso zezinga lokudla, njenge-FDA, GB 2760)

Ama-ejenti okujiya kanye neziqinisi

I-Hydroxypropyl Cellulose HPC isetshenziswa eziphuzweni (ezifana neziphuzo ze-lactic acid bacteria, amajusi ezithelo), i-ayisikhilimu, kanye nama-jam ukuthuthukisa i-viscosity yomkhiqizo, ukuthuthukisa ukuthungwa (njengokucwebezela kwe-ayisikhilimu), kanye nokuvimbela ukuhlukaniswa noma ukuhlukaniswa kwamanzi (umthamo: 0.1% kuya ku-1.0%).

I-ejenti yokwenza amafilimu

I-Hydroxypropyl Cellulose HPC isetshenziswa "efilimini yokunamathela edliwayo" yezithelo nemifino (isixazululo samanzi se-HPC siyafuthwa futhi somiswe ukuze sakhe ifilimu esobala), kunciphisa ukulahleka kwamanzi kanye nokungcola kwamagciwane, futhi kwandise isikhathi sokulondolozwa.

Isithuthukisi sokubhaka

I-Hydroxypropyl Cellulose ingezwa enhlameni yesinkwa nekhekhe ukuze kuthuthukiswe ukunwebeka kwenhlama, okwenza umkhiqizo oqediwe ube bushelelezi futhi uthambe, futhi kwandiswe isikhathi sokuphila kwayo eshalofini (umthamo uphakathi kuka-0.2% no-0.5%).

3. Emkhakheni wamakhemikhali nezimonyo zansuku zonke

Imikhiqizo yokunakekela isikhumba

I-Hydroxypropyl Cellulose, njenge-moisturizer kanye ne-thickener, isetshenziswa kuma-lotion, ama-face cream kanye nama-essence ukwandisa i-viscosity yemikhiqizo (ukuthuthukisa umuzwa wesikhumba uma isetshenziswa), futhi ngesikhathi esifanayo yakha ifilimu ebusweni besikhumba ukuze kuncishiswe ukuhwamuka kwamanzi (isikhathi sokufumisa singafinyelela emahoreni angu-4 kuya kwangu-8).

Ukulungisa

I-Hydroxypropyl Cellulose isetshenziswa ku-foundation kanye ne-mascara njenge-ejenti yokwakha ifilimu kanye ne-dispersant, okuthuthukisa ukunamathela kwezimonyo (kungenzeka ukuthi zingaphumi), futhi ngesikhathi esifanayo kwenza umbala uhlakazeke ngokulinganayo (umbala ozinzile).

Umuthi wamazinyo

I-Hydroxypropyl Cellulose, njenge-binder kanye ne-thickener, ilawula i-viscosity ye-toothpaste (ivimbela izinhlayiya eziqinile ukuthi zingahlali), ithuthukisa "umuzwa oqinile" ngesikhathi sokuxubha, futhi ayicasuli.

4. Eminye imikhakha yezimboni

Izembozo noyinki

I-Hydroxypropyl Cellulose isetshenziswa njengesithako sokujiya kanye nesithako sokulinganisa ezimbozweni ezisekelwe emanzini kanye noyinki wokuphrinta ukuvimbela ukubola kwe-pigment kanye nokuthuthukisa i-leveling properties yezimbozo (ukugwema izimpawu zamabhulashi).

Imboni yezinto zokwakha

I-Hydroxypropyl Cellulose isetshenziswa ku-cement mortar kanye ne-putty powder njenge-ejenti yokugcina amanzi (ukunciphisa ukuhwamuka kwamanzi ngokweqile nokuvimbela ukuqhekeka) kanye ne-thickener (ukuthuthukisa ukugeleza kokwakhiwa).

Izinto ze-elekthronikhi

I-HPC ehlanzekile kakhulu isetshenziswa njenge-resin eyakha ifilimu yokumelana ne-photoresist enqubweni yokukhiqiza ama-chip e-semiconductor (okuqukethwe kokungcola kumele kulawulwe ngokuqinile).
