Hydroxypropyl cellulose CAS 9004-64-2

1. Gawo la mankhwala (gawo lofunika kwambiri, liyenera kutsatira miyezo ya mankhwala, monga USP, EP, CP)

Zosakaniza za mlingo wolimba pakamwa

Chogwirizira: Hydroxypropyl Cellulose HPC imagwiritsidwa ntchito popangira mapiritsi ndi makapisozi (mwachitsanzo, pochita zonyowa, madzi a 1% mpaka 5% HPC amagwiritsidwa ntchito ngati chogwirizira kuti awonjezere kusinthasintha ndi kuuma kwa ma granules ndikuchepetsa kuchedwa kwa kusweka kwa mapiritsi).

Disintegrant: HPC yocheperako yosinthira (mlingo wosinthira 0.2-0.4), chifukwa cha kuchuluka kwa magulu a hydroxyl osatenthedwa, imakhala ndi mphamvu zotupa kwambiri ikatha kuyamwa madzi ndipo ingagwiritsidwe ntchito ngati disintegrant ya mapiritsi (mlingo wa 2% - 5%).

Zipangizo zophikira: Hydroxypropyl cellulose m'mapiritsi. HPC ethanol solution (5% - 10%) imagwiritsidwa ntchito popanga mafilimu ophikira mapiritsi kuti apange filimu yoteteza yowonekera bwino, yomwe imabisa kukoma kowawa kwa mankhwalawa, imalimbitsa kukhazikika, komanso siyimakhudza kusweka.

Zipangizo za mafupa otulutsidwa nthawi zonse: HPC yokhuthala kwambiri ingagwiritsidwe ntchito ngati matrix ya mafupa a mapiritsi otulutsidwa nthawi zonse (ndi mlingo wa 20% mpaka 50%), ndipo kuchuluka kwa mankhwala otulutsidwa kumayendetsedwa ndi kuchuluka kwa kusungunuka kwa HPC gel layer, zomwe zimapangitsa kuti kutulutsidwa kukhale kokhalitsa kwa maola 12 mpaka 24.

Zinthu zothandizira pakhungu

Hydroxypropyl Cellulose HPC imagwiritsidwa ntchito m'madontho a m'maso, ma gels ndi mafuta odzola ngati chokhuthala (kusintha kukhuthala kwa mankhwalawo ndikuwonjezera nthawi yomwe mankhwalawa amakhala pamalo omwe akugwiritsidwa ntchito) komanso chokhazikika (kuletsa kutayikira kwa tinthu ta mankhwala).

2. Hydroxypropyl cellulose mu chakudya (iyenera kutsatira miyezo ya chakudya, monga FDA, GB 2760)

Zothandizira kukhuthala ndi zokhazikika

Hydroxypropyl Cellulose HPC imagwiritsidwa ntchito mu zakumwa (monga zakumwa za lactic acid bacteria, madzi a zipatso), ayisikilimu, ndi jamu kuti ziwonjezere kukhuthala kwa mankhwala, kukonza kapangidwe kake (monga kusalala kwa ayisikilimu), ndikuletsa kugawikana kapena kulekanitsidwa kwa madzi (mlingo: 0.1% mpaka 1.0%).

Wopanga mafilimu

Hydroxypropyl Cellulose HPC imagwiritsidwa ntchito mu "filimu yodyera" ya zipatso ndi ndiwo zamasamba (HPC yamadzi imapopedwa ndikuumitsidwa kuti ipange filimu yowonekera), kuchepetsa kutayika kwa madzi ndi kuipitsidwa kwa tizilombo toyambitsa matenda, ndikuwonjezera nthawi yosungira.

Chowonjezera kuphika

Hydroxypropyl Cellulose imawonjezeredwa ku mtanda wa buledi ndi keke kuti mtandawo ukhale wofewa komanso wofewa, komanso kuti ukhale wotetezeka (mlingo wake ndi 0.2% mpaka 0.5%).

3. Mu gawo la mankhwala ndi zodzoladzola za tsiku ndi tsiku

Zosamalira khungu

Hydroxypropyl Cellulose, monga mafuta odzola komanso okhuthala, imagwiritsidwa ntchito mu mafuta odzola, mafuta odzola nkhope ndi zinthu zina kuti awonjezere kukhuthala kwa zinthuzo (kuwonjezera kumveka kwa khungu likagwiritsidwa ntchito), komanso nthawi yomweyo kupanga filimu pamwamba pa khungu kuti achepetse kutuluka kwa madzi (nthawi yonyowetsa imatha kufika maola 4 mpaka 8).

Makongoletsedwe

Hydroxypropyl Cellulose imagwiritsidwa ntchito mu maziko ndi mascara ngati chopangira filimu komanso chotulutsira utoto, zomwe zimapangitsa kuti zodzoladzola zikhale zolimba (nthawi zambiri sizingachoke), komanso nthawi yomweyo zimapangitsa kuti utotowo ufalikire mofanana (mtundu wokhazikika).

Mankhwala otsukira mano

Hydroxypropyl Cellulose, monga chomangira ndi chokhuthala, imawongolera kukhuthala kwa mano otsukira mano (kuletsa tinthu tolimba kuti tisakhazikike), imawongolera "kumveka ngati zingwe" mukamatsuka mano, ndipo siikwiyitsa.

4. Magawo ena a mafakitale

Zophimba ndi inki

Hydroxypropyl Cellulose imagwiritsidwa ntchito ngati chokhuthala komanso cholemeretsa mu zophimba zochokera m'madzi ndi inki zosindikizira kuti zisawononge utoto ndikuwongolera mphamvu ya zophimbazo (kupewa zizindikiro za burashi).

Makampani opanga zida zomangira

Hydroxypropyl Cellulose imagwiritsidwa ntchito mu simenti ndi ufa wa putty ngati chosungira madzi (kuchepetsa kuuma kwa madzi ambiri ndikuletsa ming'alu) komanso chokhuthala (kuwonjezera kusinthasintha kwa kapangidwe kake).

Zipangizo zamagetsi

HPC yoyera kwambiri imagwiritsidwa ntchito ngati utomoni wopanga filimu wa photoresist popanga ma chip a semiconductor (zodetsa ziyenera kulamulidwa mosamala).
