Kusiyana pakati panjihydroxypypyl methylcellulose(Hpmc) ndi kapena kapena s?
1.
Mtundu wa HPMC mwachangu umadzaza ndi chilembo S. Pa nthawi yopanga, Glyloxal ayenera kuwonjezeredwa.
Mtundu wa HPMC sunawonjezere zilembo zilizonse, monga "100000" ndi "100000 viscyvess diprs Happy mtundu hpmc".
2. Ndi kapena wopanda s, mikhalidweyi ndi yosiyana
Kufalikira mwachangu kwa HPMC kumabala mwachangu m'madzi ozizira ndikuzimiririka m'madzi. Pakadali pano, madziwo alibe mamasukidwe, chifukwa HPMC imangomwazika m'madzi, ndipo palibe kufalikira kwenikweni. Patatha pafupifupi mphindi ziwiri, mamasukidwe amadzimadzi pang'onopang'ono amawonjezeka, ndikupanga madzi ophikira. Colloid wandiweyani.
Nthawi yomweyo hpmc imatha kufalitsa mwachangu m'madzi otentha nthawi pafupifupi 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. Mu glues wamadzimadzi, zokutira ndi zoyeretsa, zotchinga zidzachitika ndipo sizingagwiritsidwe ntchito.
Kufalikira mwachangu hpmc kuli ndi ntchito zingapo. Itha kugwiritsidwa ntchito mu ufa wa putty, matope, guluu wamadzimalo, utoto, ndi kusamba zinthu popanda kutsutsana.
Njira Yokhutira
1. Tengani kuchuluka kwa madzi otentha, ikani chidebe ndikuchitenthe pamwamba pa 80 ° C, ndipo pang'onopang'ono onjezani pang'onopang'ono malondawo pansi pa kusuntha pang'onopang'ono. Cellulose yoyandama pamadzi poyamba, koma pang'onopang'ono amabalalitsidwa kupanga yunifolomu. Kuzizira yankho ndi oyambitsa.

4. Onjezani ma cellulose pang'onopang'ono komanso mobwerezabwereza kutentha kwa firiji, ndikupitilizabe kulimbikitsa nthawi yowonjezera mpaka yankho lowunikiridwa.
Ndi zinthu ziti zomwe zimakhudza kusungidwa kwamadzi kwa hydroxypropyl methylcelulose?
Kusunga kwamadzi kwa hydroxpyl methylcellulose zinthu zomwe zimakhudzidwa ndi zinthu zotsatirazi:
1. Cellulose ether hpmc homogeneity
Kuchita bwino kwa HPMC kuli ngati kufalitsa kwa methoxy ndi hydroxyprophiroxy magulu ndi kusungidwa kwamadzi kwambiri.
2. Cellulose etherc hpmc kutentha kwa gel
Kutentha kwa mafuta kwa gel osakaniza, kuchuluka kwa madzi osunga madzi; Kupanda kutero, kutsitsa madzi osunga madzi.
3. Treuluse ether hpmc
Pamene mafakidwe a HPMC amawonjezeka, kuchuluka kwa madziwo kumawonjezekanso. Mawonekedwe akafika pamlingo wina, kuwonjezeka kwa malo osungira madzi kumatenga kuti akhale odekha.
Cellulose ether hpmc kuwonjezera
Chokulirapo chowonjezera cha cellulose ether hpmc, malo osungira madziwo ndi madzi osungitsa madzi.
Mu mitundu ya 0,25-0.6%, kuchuluka kwa madzi kumawonjezera mwachangu ndi kuchuluka kwa kuchuluka kwa zowonjezera; Kuphatikiza apo kumawonjezeranso, zomwe zimachitika kuti madzi osungitsa madzi ayamba pang'onopang'ono.
