Mukawonjezera hydroxypropyl methylcellulose kuzinthu zopangidwa ndi simenti, imatha kukhuthala. Kuchuluka kwa hydroxypropyl methylcellulose kumatsimikizira kufunikira kwa madzi kwa zinthu zopangidwa ndi simenti, motero zimakhudza kutulutsa kwamatope.
Zinthu zingapo zimakhudza kukhuthala kwa hydroxypropyl methylcellulose:
1. Kuchuluka kwa ma polymerization a cellulose ether, kukula kwake kwa maselo, komanso kukulitsa kukhuthala kwa njira yamadzi;
2. Kuchuluka kwa kudya (kapena kuchuluka) kwa cellulose ether, kumapangitsanso kukhuthala kwake kwamadzimadzi. Komabe, m'pofunika kusamala posankha kudya koyenera panthawi yogwiritsira ntchito kuti tipewe kudya kwambiri, zomwe zingakhudze ntchito ya matope ndi konkire. khalidwe;
3. Monga zamadzimadzi zambiri, kukhuthala kwa cellulose ether solution kudzachepa ndi kuchuluka kwa kutentha, ndipo kuchuluka kwa cellulose ether kumapangitsanso kutentha kwambiri;
4. Hydroxypropyl methylcellulose solution kawirikawiri ndi pseudoplastic, yomwe imakhala ndi kumeta ubweya wa ubweya. Kuchuluka kwa kumeta ubweya wa ubweya panthawi yoyesedwa, kumachepetsa kukhuthala.
Choncho, kugwirizana kwa matope kudzachepa chifukwa cha mphamvu yakunja, yomwe imakhala yopindulitsa pakupanga matope, zomwe zimapangitsa kuti pakhale ntchito yabwino komanso kugwirizana kwamatope nthawi yomweyo.
Njira ya hydroxypropyl methylcellulose idzawonetsa mikhalidwe yamadzimadzi a Newtonian pamene ndende imakhala yotsika kwambiri ndipo kukhuthala kuli kochepa. Pamene ndende ikuwonjezeka, yankho lidzawonetsa pang'onopang'ono makhalidwe a pseudoplastic fluid, ndipo kumtunda kwa ndende, kumakhala koonekeratu pseudoplasticity.
