Hydroxypropyl methyl cellulose VS methyl cellulose

1. Hydroxypropyl methyl cellulosesungunuka m'madzi ozizira, madzi otentha osungunuka amakumana ndi zovuta. Koma kutentha kwake kwa gelation m'madzi otentha ndikokwera kwambiri kuposa kwa methyl cellulose. Kusungunuka kwa methyl cellulose m'madzi ozizira kumakhalanso bwino kwambiri.

2. Kukhuthala kwa hydroxypropyl methyl cellulose kumagwirizana ndi kulemera kwake kwa maselo, ndipo kulemera kwake kwa maselo ndikokwera kwambiri. Kutentha kudzakhudzanso mamasukidwe ake, kutentha kumawonjezeka, kukhuthala kumachepa. Komabe, kukhuthala kwa kutentha kwakukulu ndi kotsika kuposa kwa methyl cellulose. Yankho lake ndi lokhazikika likasungidwa kutentha.

3. Hydroxypropyl methyl cellulose imakhala yokhazikika ku asidi ndi alkali, ndipo njira yake yamadzimadzi imakhala yokhazikika kwambiri mu pH = 2 ~ 12. Koloko ndi madzi a mandimu alibe zotsatira zabwino pa katundu wake, koma zamchere zimatha kufulumizitsa kusungunuka kwake ndikuwongolera kukhuthala kwa pini. Hydroxypropyl methyl cellulose imakhala yokhazikika ku mchere wamba, koma mchere ukakhala wambiri, kukhuthala kwa hydroxypropyl methyl cellulose solution kumawonjezeka.

4. Kusungidwa kwa madzi kwa hydroxypropyl methyl cellulose kumadalira kuchuluka kwake, kukhuthala kwake, ndi zina zotero. Mlingo wosungira madzi pansi pa kuchuluka komweko wowonjezera ndi wapamwamba kuposa wa methyl cellulose.

5. Kumamatira kwa hydroxypropyl methyl cellulose kumapangidwe amatope ndikokwera kuposa methyl cellulose.

6. Hydroxypropyl methyl celluloseali ndi kukana bwino kwa enzyme kuposa methyl cellulose, ndipo kuthekera kwa kuwonongeka kwa enzymatic mu yankho ndikotsika kuposa methyl cellulose.
