Ingoweruzani mtundu wa hydroxypropyl methylcellulose

Hydroxypropyl methylcelluloseali ndi thickening, kumanga, kubalalitsa, emulsifying, filimu kupanga, suspending, adsorbing, gelling, pamwamba yogwira, kusunga chinyezi ndi kuteteza colloid katundu. Mitundu ya ntchito ndi yotakata kwambiri.

Ubwino

Ubwino wa hydroxypropyl methylcellulose nthawi zambiri umakhala ndi mauna 80 ndi mauna 100. Kukongoletsedwa bwino, kusungunuka kwachangu, nthawi zambiri kumakhala bwino. Nthawi zambiri, ofukula riyakitala kubala woonda mankhwala kuposa yopingasa riyakitala.

Kutumiza

Sungunulani hydroxypropyl methylcellulose (HPMC) m'madzi kuti mupange madzi owonekera. Yang'anani kuwala kwake. Kuchuluka kwa kuwala kwamagetsi, kumakhala bwinoko, kusonyeza kuti muli ma insolubles ochepa mmenemo.

gawo

Kukula kwapakati ndikwabwinoko. Ngati mphamvu yokoka ndi yayikulu kwambiri kapena yaying'ono kwambiri, zitha kukhala chifukwa cha kusawongolera bwino panthawi yopanga.

Kunja

Hydroxypropyl methylcellulose yoyera ndi yowoneka bwino ndipo imakhala yochepa kwambiri, kuyambira 0.3-0.4g/ml; HPMC wonyengedwa ali ndi madzimadzi bwino ndipo amamva kulemera, zomwe mwachiwonekere zimasiyana ndi mankhwala enieni m'mawonekedwe. Maonekedwe a cellulose ena opangidwa ndi cholinga chapadera amasiyananso kwambiri ndi zomwe zimachitika kawirikawiri, ndipo zinthu zinazake zimawunikidwa mwatsatanetsatane.

njira yamadzimadzi

Koyera HPMC amadzimadzi yothetsera ndi bwino, mkulu kuwala transmittance, madzi posungira mlingo ≥ 90%; HPMC amadzimadzi yothetsera vutoli ndi turbid, ndipo mlingo posungira madzi n'zovuta kufika 70%

BaiDu

Ngakhale kuyera sikungadziwe ngatiMtengo wa HPMCndizosavuta kugwiritsa ntchito, ndipo ngati zoyera zimawonjezeredwa panthawi yopanga, zimakhudza mtundu wake. Komabe, zinthu zambiri zabwino zimakhala ndi zoyera zabwino.
