Njira yothetsera hydroxypropyl methylcellulose (HPMC)

Hydroxypropyl methylcellulose (HPMC) amagwiritsidwa ntchito kwambiri mu zomangamanga, zokutira, utomoni kupanga, zoumba, mankhwala, chakudya, nsalu, ulimi, zodzoladzola, fodya ndi mafakitale ena. Hydroxypropyl methylcellulose (HPMC) ndi ether yosakhala ionic cellulose yopangidwa kuchokera ku cellulose yachilengedwe ya polima kudzera munjira zingapo zama mankhwala. Hydroxypropylmethylcellulose (HPMC) ndi ufa woyera wopanda fungo, wosakoma, wopanda poizoni womwe ukhoza kusungunuka m'madzi ozizira kuti ukhale wowonekera bwino wa viscous. Lili ndi makhalidwe a thickening, kumanga, kubalalika, emulsifying, filimu kupanga, suspending, adsorbing, gelling, pamwamba yogwira, kusunga chinyezi ndi kuteteza colloid.

Njira yothetsera hydroxypropyl methylcellulose (HPMC):

Mankhwalawa amafufuma ndikubalalika m'madzi otentha opitilira 85 ° C, ndipo nthawi zambiri amasungunuka ndi njira izi:

1. Tengani 1/3 ya madzi otentha ofunikira, yambitsani kuti musungunule mankhwala owonjezera, kenaka yikani madzi ena otentha, omwe angakhale madzi ozizira, kapena madzi oundana, ndikugwedeza mpaka kutentha koyenera (20). °C), ndiye idzasungunuka kwathunthu. ndi

2. Kuwumitsa ndi kusakaniza:

Pankhani yosakanikirana ndi ufa wina, uyenera kusakanikirana bwino ndi ufa musanawonjezere madzi, ndiye ukhoza kusungunuka mwamsanga popanda agglomeration. ndi

3. Njira yonyowetsa zosungunulira za organic:

Choyamba kumwaza mankhwala mu zosungunulira organic kapena kunyowetsa ndi organic zosungunulira, ndiyeno kuwonjezera madzi ozizira kupasuka bwino.
