Kodi kukhuthala kwa hydroxypropyl methyl cellulose aqueous solution ndi chiyani?

Hydroxypropyl methyl cellulose ili ndi chiyembekezo chokulirapo pantchito yomanga, ndipo kukhuthala kwake komanso kusunga madzi kumapangitsa kuti ntchito yake yomanga isanyalanyazidwe.Koma kodi tikudziwa bwanji za ubwino wake?Tsopano tiyeni tikambirane za kukhuthala kwamphamvu kwa hydroxypropyl methyl cellulose amadzimadzi.

Hydroxypropyl methyl cellulose amadzimadzi njira yosavuta mawu oyamba: English chidule HPMC non-ionic, madzi sungunuka mapadi efa, maonekedwe woyera kapena kuwala chikasu ufa kapena granular chuma.Zake zoipa, odorless, sanali poizoni, khola mankhwala katundu m'madzi kupanga yosalala pang'ono mandala viscous madzi.

Kodi ndi zinthu ziti zomwe zimakhudza kukhuthala kwa hydroxypropyl methyl cellulose aqueous solution?
1.Ubale ndi ma polima: kukhuthala kwa hydroxypropyl methyl cellulose yamadzimadzi amadzimadzi kumayenderana ndi kulemera kwa polima kapena molekyulu, ndipo kumawonjezeka ndikusintha kwa digiri ya polymerization.Zimenezi n'zoonekeratu kwambiri pa nkhani ya otsika polymerization kuposa nkhani ya mkulu polymerization.
2.Ubale pakati pa mamasukidwe akayendedwe ndi ndende: kukhuthala kwa hydroxypropyl methyl cellulose mu njira yamadzimadzi kumawonjezeka ndi kuchuluka kwa njira yamadzimadzi, ndipo ngakhale kusintha pang'ono kwa ndende kungayambitse kusintha kwakukulu kwamawonekedwe.
3.Ubale pakati pa viscosity ndi shear rate: Mayesowa akuwonetsa kuti hydroxypropyl methyl cellulose alibe kusintha kwakukulu pamlingo wocheperako wometa ubweya, ndipo kukhuthala kumachepa ndi kuchuluka kwa shear.
4.Ubale pakati pa mamasukidwe akayendedwe ndi kutentha: hydroxypropyl methyl cellulose imakhudzidwa kwambiri ndi kutentha, ndipo mamasukidwe ake amachepa ndi kuwonjezeka kwa kutentha.
5.Zina: kukhuthala kwa hydroxypropyl methyl cellulose ndi zowonjezera zosiyanasiyana, mayankho, ma PH amakhudzanso.

Tikamachita mayeso a labu tiyenera kudziwa za mawonekedwe a viscosity ya hydroxypropyl methyl cellulose amadzimadzi?
