Kodi kukhuthala kwa HPMC E5 ndi chiyani?

HPMC E5 ndi low-molecular-weight hydroxypropyl methylcellulose (HPMC) yomwe imagwiritsidwa ntchito ngati thickening, suspending, and emulsifying agent muzinthu zosiyanasiyana. Ndi ufa woyera, wopanda fungo, wopanda kukoma womwe umasungunuka m'madzi ozizira komanso osasungunuka m'madzi otentha. Amagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo zakudya, mankhwala, ndi zodzoladzola.

Kukhuthala kwa HPMC E5 kumayesedwa mu centipoise (cP). Uwu ndi muyeso wa kukana kwa madzi kuti usayende, ndipo umasonyezedwa ngati kuchuluka kwa mphamvu yofunikira kusuntha voliyumu yamadzimadzi pa liwiro loperekedwa. Kukhuthala kwa HPMC E5 kumatha kuyambira 4 mpaka 6 cP, kutengera kuchuluka kwa yankho ndi kutentha.

Pa ndende ya 1%, kukhuthala kwa HPMC E5 kumakhala kozungulira 5 cP. Pa ndende ya 2%, kukhuthala kumawonjezeka mpaka 5 cP. Pa ndende ya 3%, kukhuthala kumawonjezeka mpaka 5 cP. Pa ndende ya 4%, kukhuthala kumawonjezeka mpaka 5 cP.

Mwachidule, kukhuthala kwa HPMC E5 kumatha kuyambira 1 mpaka 100,000 cP, kutengera kuchuluka kwa yankho, kutentha, ndi pH. Pamagulu a 1%, kukhuthala kwake kumakhala pafupifupi 5 cP. Pamalo okwera kwambiri, mamasukidwe amachulukidwe amawonjezeka, ndipo pa kutentha kwakukulu ndi pH mlingo wapamwamba, kukhuthala kumawonjezekanso.
