Hydroxypyl methyl celluse vs methyl cellulose

1. Hydroxypropyll Methyl cellulose yosungunuka m'madzi ozizira, madzi otentha osungunuka amakumana ndi zovuta. Koma kutentha kwake kwamadzi otentha kumakhala kokulirapo kuposa kwa methyl cellulose. Kusungunuka kwa methyl cellulose m'madzi ozizira kumasinthanso kwambiri.

2. Makulidwe a hydroxypropyl meth cellose amakhudzana ndi kulemera kwake, ndipo kulemera kwakukulu kwa ma vilecular ndi mamasukidwe apamwamba kwambiri. Kutentha kumakhudzanso ma viwawo, kutentha kumawonjezeka, mafayilo amachepa. Komabe, mawonekedwe owoneka bwino otsika kwambiri kuposa a methyl cellulose. Njira yothetsera vutoli ndi yokhazikika ikasungidwa kutentha.

3. Hydroxypropyl methy cellose ndi yokhazikika kwa asidi ndi alkali, ndipo yankho lake la madzi ndi lokhazikika mu pH = 2 ~ 12. Caustic Soda ndi Madzi a laimu alibe mphamvu pazinthu zake, koma alkali amatha kusamalira kuchuluka kwake ndikusintha mafayilo a pini. Hydroxypropyl methy cellulose imakhala ndi mchere wambiri, koma pamene kuchuluka kwa mchere ndi yayitali, mamasukidwe a hydroxypropyl cellouse yankho.

4. Kusunga kwamadzi kwa hydroxypropyl methy cellose kumadalira kuchuluka kwake, mafayilo am'madzi omwe ali ndi ndalama zofananira ndi zapamwamba kuposa cellouse.

5. Kumatira kwa hydroxypropyl methy cellouse ku matope omanga ndi apamwamba kuposa a methyl cellulose.

6. Hydroxypropyl methy celyose ili ndi enzyme yolimba kuposa methyl cellulose, komanso kuthekera kwa enzymatic kuwonongeka kotheratu ndikotsika kuposa cellulose.
