Momwe mungagwiritsire ntchito hydroxypropyll methylcelulose

Hydroxypylropyl (HPMC) ndi ma cellulose omwe amagwiritsidwa ntchito kwambiri m'matoto omanga, mankhwala, chakudya, mankhwala tsiku lililonse.

1. Makhalidwe Oyambira
Kusungunuka: HPMC imasungunuka m'madzi ozizira ndi ena okhazikika, ndipo mankhwala ake am'madzi satenga nawo mbali kapena ofowoka alkaline.
Kukula: HPMC ili ndi luso labwino kwambiri ndipo limatha kusintha mamasukidwe ndi thixotropy ya nkhaniyi.
Kusungidwa kwamadzi: kumatha kupitirira nthawi yopanduka yamadzi ndikusintha magwiridwe antchito.
Katundu wopanga makanema: hpmc amatha kupanga filimu yowonekera komanso yosinthika.
Thermogelation: Iyo idzatentha kutentha kwina ndikubwerera ku dziko losungunuka pambuyo pozizira.

2. Momwe Mungagwiritsire Ntchito
Masitepe Osiyanasiyana
HPMC imayenera kusungunuka bwino mukamagwiritsa ntchito njira yake:
Kusintha kwamadzi kozizira:
Kuwaza HPMC pang'onopang'ono m'madzi ozizira kupewa kuphatikizika.
Onjezani poyambitsa kupanga osakanikirana.
Nditayimirira kwa nthawi yayitali (pafupifupi mphindi 30 mpaka maola angapo), HPMC imasungunuka kuti apange yankho.
Kusintha kwa madzi otentha:
Sakanizani hpmc ndi madzi otentha (pamwamba pa 70 ° C) ndikuyambitsa kubereka.
Pambuyo pozizira, onjezani madzi ozizira ndikupitiliza chosangalatsa mpaka utasungunuka kwathunthu.
Njirayi ndiyoyenera kuchitika komwe yankho liyenera kukonzedwa mwachangu.

Kulamulira zinthu mozama
Malinga ndi momwe amagwirira ntchito, kuchuluka kwa HPMC kuyenera kusintha:
Gawo lomanga: Nthawi zambiri zimakonzedwa ngati 0,1% ~ 1% ya aluth, makamaka imagwiritsidwa ntchito pomacheza, putty ufa, tile zomata, etc.
Chakudya Chomwe: Kugwiritsa ntchito nthawi zambiri kumakhala 0,05% ~ 0,5%, kutsimikiza malinga ndi malamulo owonjezera chakudya.
Gawo la zamankhwala: HPMC ndi yosangalatsa pa mapiritsi a mankhwala, ndipo kuchuluka kwake kumafunikira kuwongolera kuti awonetsetse mankhwala osokoneza bongo.

Gwiritsani ntchito kukonza
Makampani omanga:
Mu ufa wa putty ndi matope, choyamba kusuta hpmc m'madzi, kenako osakaniza mogwirizana ndi zina zophatikizira molingana.
Mukamagwiritsa ntchito tile zomatira, hpmc imatha kusintha mamasukidwe ndi anti-slip.
Gawo la mankhwala:
Itha kugwiritsidwa ntchito mwachindunji pokutidwa ndi mapiritsi opanga mapiritsi kuti muchepetse kusokonekera ndi kumasula.
Tsiku lililonse Mankhwala:
Amagwiritsidwa ntchito ngati thicker kapena emulsifier okhazikika m'malo oyeretsa ndi mawonekedwe a nkhope.
Utoto Wapakati:
Imagwiritsidwa ntchito ngati thickiner mu utoto wa mochedwa kuti mupewe matenda a pigment.
3. Kusamala
Kutentha kwa kutentha: Kusungunuka kwa HPMC kumagwirizana kwambiri ndi kutentha. Kutentha kwakukulu kumatha kuyambitsa miyeso, motero tikulimbikitsidwa kuti muzigwiritsa ntchito m'madzi ozizira kupewa kukayikira.
Njira yosangalatsa: khalani mwachisokonezo pang'onopang'ono komanso mozama kupewa ma thovu ochuluka chifukwa chogwira ntchito mwamphamvu.
Storage conditions:
Pewani kuwonekera malo achilengedwe.
Pewani kulumikizana ndi acid amphamvu, alkali olimba kapena oxidants.
Chitetezo: HPMC sikuti zida zopweteka komanso zopanda pake, koma zotchinga ziyenera kuvalidwa panthawi ya ufa kuti mupewe kupweteka kapena kulumikizana ndi maso.
Kudutsa kuwonongeka koyenera ndikugwiritsa ntchito, hydroxypropyll methylcellulose imatha kusewera kwambiri, kusungidwa kwamadzi, kutsatira komanso kukhazikika kwamitundu yosiyanasiyana.
