1. HPMC imagawidwa kuti ikhale mtundu wambiri komanso mtundu wambiri wobalalitsa.
Mtundu wa HPMC Rever wobalalika uli ndi chilembo chosakwanira. Glyloxal iyenera kuwonjezeredwa pakupanga.
Mtundu wachangu wa HPMC sukuwonjezera zilembo zilizonse, monga "100000" amatanthauza "ma Isccton ofatsa hpmc".
2. Ndi kapena wopanda s, mikhalidweyi ndi yosiyana
Kufalikira mwachangu hpmc mofulumira kufalikira m'madzi ozizira ndikuzimiririka m'madzi. Madzimadzi alibe mafakisoni panthawiyi chifukwa HPMC imangomwazika m'madzi ndipo osasungunuka kwenikweni. Patatha pafupifupi mphindi ziwiri, mafayilo amadzimadzi pang'onopang'ono amawonjezeka, ndikupanga madzi owoneka bwino. Colloid wandiweyani.
Nthawi yomweyo hpmc imatha kubalalitsidwa mwachangu m'madzi otentha nthawi zonse 70 ° C. Kutentha pakagwa mpaka kutentha kwinakwake, ma viwawo amawoneka pang'onopang'ono mpaka Collous yowonekera bwino imapangidwa.
3. Ndi kapena popanda, cholinga chake ndi chosiyana
Nthawi yomweyo hpmc imatha kugwiritsidwa ntchito mu ufa ndi matope. M'magulu amadzimadzi, utoto ndi zoyeretsa, ma cumps amatha kuchitika ndikusasinthika.
Kufalikira mwachangu hpmc kuli ndi ntchito zingapo. Itha kugwiritsidwa ntchito ngati ufa wa punty, matope, guluu wamadzimalo, penti, ndikuyeretsa zinthu popanda kutsutsana.
Njira Yokhutira
1. Tengani kuchuluka kwa madzi otentha, ikani chidebe ndikuchitenthe pamwamba pa 80 ℃, ndiye pang'onopang'ono onjezani izi ndikusintha pang'onopang'ono. Cellulose yoyandama pamadzi poyamba, koma amabalalitsa pang'onopang'ono kupanga yunifolomu. Kuziziritsa yankho mukamayambitsa.
2.
3. Cellulose ili ndi kukula kwa machesi komanso kumakhalapo ngati tinthu tating'onoting'ono tomwe timakhala osakhazikika. Imasungunuka mwachangu ikawonekera ndi madzi kuti apange mawonekedwe ofunikira.
4. Onjezani ma cellulose pang'onopang'ono komanso mobwerezabwereza kutentha kwa firiji, oyambitsa mosalekeza mpaka yankho labwino.
Ndi zinthu ziti zomwe zimakhudza kusungidwa kwamadzi kwa hydroxypropyl methylcelulose?
Kusunga kwamadzi kwa hydroxpyl methylcellulose zinthu zomwe zimakhudzidwa ndi zinthu zotsatirazi:
1.
Magulu osagwirizana ndi HPMC Methoxy ndi Hydroxyprovoy amagawidwa ndipo ali ndi madzi ambiri.
2. Cellulose etherc hpmc kutentha kwa gel
Kutentha kwa mphamvu ya mphamvu ya gel, malo osungitsa madzi; mosiyanasiyana, kutsitsa madzi kusunga madzi.
3. Makulidwe a cellulose ether hpmc
Pamene mafakidwe a HPMC amawonjezeka, kuchuluka kwa madziwo kumawonjezekanso. Mawonekedwe akafika pamlingo winawake, kuwonjezeka kwa madzi osunga madzi kumakhala odekha.
Cellulose ether hpmc kuwonjezera
Kuchuluka kwa cellulose ether hpmc kuwonjezera, kuchuluka kwa malo osungitsa madzi ndikuwongolera madzi.
Mu mitundu ya 0,25-0.6%, kuchuluka kwa madzi kumachulukanso mwachangu monga momwe kuphatikiza kumawonjezeka; Kuphatikiza apo kumawonjezeka, kuchuluka kwa kuchuluka kwa madzi osunga madzi kumachepa.
