EipponCell MHEC LH 620M methyl hydroxyethyl cellulose amagwiritsidwa ntchito mu gypsum slurry kuti apereke mawonekedwe owoneka bwino.Pa kutentha kwa firiji, pamene mamasukidwe akayendedwe ndi mlingo wa cellulose ether ukuwonjezeka, kukhuthala kwake kumawonekera kwambiri.Komabe, kutentha kukamakwera, kukhuthala kwa cellulose ether kumachepa, zomwe zimapangitsa kufooka kwa kukhuthala kwake.Izi zimabweretsa kuchepa kwa kumeta ubweya wa zokolola, kukhuthala kwa pulasitiki, ndi pseudoplasticity ya osakaniza a gypsum, zomwe zimabweretsa kusagwira bwino ntchito.
Cellulose ether imathandizira kusungidwa kwa madzi kwa gypsum.Komabe, kutentha kumawonjezeka, kusungidwa kwa madzi kwa gypsum yosinthidwa kumachepa kwambiri ndipo ngakhale kutaya mphamvu yake yosungira madzi pa 60 ° C.Kuchuluka kwa madzi osungira madzi a gypsum slurry kumakhala bwino kwambiri ndi cellulose ether, ndipo mlingo wosungira madzi pang'onopang'ono umafika pa malo odzaza ndi kuwonjezeka kwa zomwe zili mu HPMC yosinthidwa gypsum slurry ndi ma viscosities osiyanasiyana.Nthawi zambiri, kusungidwa kwa madzi kwa gypsum kumayenderana ndi kukhuthala kwa cellulose ether, koma kumakhala ndi zotsatira zochepa pa kukhuthala kwakukulu.
Kusintha kwa kusungidwa kwa madzi kwa ma cellulose ethers ndi kutentha kumagwirizana kwambiri ndi kapangidwe kakang'ono ka cellulose ethers mu gawo lamadzimadzi.Pazigawo zina, cellulose ether imakonda kuphatikizira ndikupanga mayanjano akuluakulu a colloidal, kutsekereza njira zoperekera madzi za gypsum osakaniza kuti akwaniritse bwino kusunga madzi.Komabe, pamene kutentha kumakwera, matenthedwe a gelation a cellulose ether amachititsa kuti mayanjano akuluakulu a colloidal omwe adapangidwa kale abalalikenso, zomwe zimapangitsa kuchepa kwa madzi.
