Kodi hpmc ndi cmc kusakaniza
Methyl cellulosendi loyera kapena loyera ngati ufa kapena glanlar ufa; Fungo lopanda tanthauzo. Izi m'madzi mumatupa mu njira yodziwikiratu kapena pang'ono ya conloidal; Zopanda malire mu Mthetherthal, chloroform kapena diethyl ether. Imabalalika mwachangu komanso yotupa m'madzi otentha pa 80-90 ℃, ndipo adasungunuka msanga. Njira yothetsera matendawa imakhala yokhazikika mu kutentha kwa firiji, ndipo imatha kuthina kutentha kwambiri, ndipo gel imasintha ndi yankho ndi kutentha.
Ili ndi utoto wabwino kwambiri, kubalalitsidwa, kotsatira, kukula, kukula, emulsization, kusungidwa kwamadzi komanso mapangidwe a filimu, komanso kusokonekera kwa mafuta. Kanemayo ali ndi kulimba kwambiri, kusinthasintha komanso kuwonekera. Chifukwa siyopanda Ionic, zitha kukhala yogwirizana ndi ma emulsifiers ena, koma ndizosavuta kuti mcherewu ukhale wokhazikika pa cellulose ya ma cellose g / cubimemeter ya sebimemeter, pafupifupi fungo labwino, yopanda pake, hygroscopic. Yosavuta kufalitsa madzi mu madzi a gelatinous gelatinous yankho, influble mu ethanol ndi zina zosungunulira.
Pamene pH ya fund ndi 6.5 - 8.5, mamasukidwe a slurry amatsika kwambiri pomwe PH ndi> kukhazikika kwa mafilimu a 45 ℃, ndi mafayilo a colloud pomwepo atatenthedwa kwa 80 ℃. Kusungunuka mosavuta m'madzi, yankho lowonekera; Imakhazikika kwambiri mu alkaline, komanso yosavuta hydrolyze pa nkhani ya asidi. Mtengo wa PH ndi 2-3, mpweya udzachitika, ndipo mpweya umachitika, ndipo chidzachitikenso kudzakhalanso ndi mchere wa mitundu yosiyanasiyana. Hydroxypyl methl cellulose, yomwe imadziwikanso kuti hydroxypropyl methy celyl ethelose, ndikusankhidwa kwa celron yapamwamba kwambiri, yomwe ikukonzekera.
Sungunulani m'madzi ndi polar c ndi gawo loyenerera la ethanol / madzi, propanol / madzi, acetone, mithete, yotupa m'madzi ozizira kapena otupa pang'ono. Njira yothetsera matendawa imakhala ndi zochitika zapamwamba, kuwonekera kwambiri komanso kusakhazikika.Hpmcali ndi malo otentha. Pambuyo potenthetsa, mankhwala a madzi am'madzi a mankhwalawa pamtunda, kenako amasungunuka pambuyo pozizira. Kutentha kwa gel kuli kosiyana.
