Kugawa kwa HPMC ndi njira yopuma

1.Clation:

HPMC ikhoza kugawidwa mu mtundu wa nthawi yomweyo komanso mtundu wosungunuka. Zogulitsa zomwe zimabalalika mwachangu m'madzi ozizira ndikuzimiririka m'madzi. Pakadali pano, madziwa alibe mamasukidwe, chifukwa HPMC imangomwazika m'madzi ndipo ilibe chisinthiko chenicheni. Patatha pafupifupi mphindi ziwiri, mawike amadzimadzi pang'onopang'ono amawonjezeka kuti apange collous yowonekera. Zogulitsa zotentha, mukakumana ndi madzi ozizira, zimatha kusungidwa mwachangu m'madzi otentha ndikuzimiririka m'madzi otentha. Kutentha pakagwa mpaka kutentha kwinakwake, ma viwawo amawoneka pang'onopang'ono mpaka Collous yowonekera bwino imapangidwa. Mtundu wosungunuka umatha kugwiritsidwa ntchito mu ufa ndi matope. M'magulu a udzu ndi utoto, chopindika chodabwitsa chidzachitika ndipo sichingagwiritsidwe ntchito. Mtundu wa nthawi yomweyo umakhala ndi ntchito zambiri. Itha kugwiritsidwa ntchito mu ufa ndi matope, komanso matalala okwanira komanso utoto, popanda contacation.

Njira ya 2.Dissess:

Njira yotentha yosungunuka: Popeza HPMC siyikusungunuka m'madzi otentha, hpmc imatha kukhala yobalalika m'madzi otentha nthawi yoyamba, kenako kusungunuka mwachangu pakuzizira. Njira ziwiri zofananira zimafotokozedwa motere: 1), ikani ndalama zomwe zimafunikira mu chidebe chamadzi otentha ndikutenthetsedwa pafupifupi 70 ° C. The hydroxypropyl pang'onopang'ono idawonjezeredwa pang'onopang'ono poyambitsa pang'onopang'ono, poyamba HPMC idayandama m'madzi, kenako pang'onopang'ono adapanga malo osalala, omwe adakhazikika ndi osokoneza. 2) Kenako onjezani kuchuluka kwa madzi ozizira kumadzi otentha mu slurry, osakaniza adakhazikika pambuyo poyambitsa.

Njira yosakanikirana: Sakanizani ufa wa hpmc wokhala ndi zinthu zina zambiri za ufa, kusakaniza bwino ndi chosakanizira, kenako ndikuwonjezera madzi pang'ono kumatha kusungunuka pomwepo kumatha kulumikizana ndi madzi. Njira ya --this imagwiritsidwa ntchito ndi ufa ndi opanga matope. [Hydroxypypyl methylcellulose (hpmc) imagwiritsidwa ntchito ngati thickener ndi wogulitsa madzi mu matope a ufa]
