N'ime ngwa ngwa agwakọta agwakọta akọrọ, ọdịnaya nke HPMCE dị obere, mana ọ nwere ike melite arụmọrụ ngwa ngwa mmiri. Nhọrọ ezi uche dị na ya nke cellulose ether dị iche iche, dị iche iche viscosity, dị iche iche urughuru size, dị iche iche viscosity ogo na mgbakwunye ego nwere mmetụta na arụmọrụ nke akọrọ ngwa agha. Ugbu a, ọtụtụ masonry na plasta ngwa agha njigide mmiri adịghị mma, a nkeji ole na ole ga-apụta a obere static water slurry nkewa. Njide mmiri bụ ihe dị mkpa nke Methyl cellulose ether, nke na-emetụtakwa ọtụtụ ndị na-emepụta ngwa agha akọrọ na China, karịsịa na ndịda ebe okpomọkụ dị elu. Ihe ndị na-emetụta njide mmiri nke ngwa ngwa akọrọ gụnyere ọnụọgụ cellulose ether HPMC, viscosity nke cellulose ether HPMC, ịdị mma nke ihe ndị ahụ na okpomọkụ nke gburugburu ebe obibi. Cellulose ether bụ ụdị polymer sịntetik nke sitere na cellulose eke sitere na mgbanwe kemịkalụ. The mmiri-soluble cellulose ether na-arụ ọrụ dị mkpa na ngwa agha n'akụkụ atọ, otu bụ magburu onwe mmiri-ejide ikike, nke ọzọ bụ mmetụta na ngwa agha agbanwe agbanwe na thixotropy, na nke atọ bụ mmekọrịta na ciment. Ọrụ na-ejigide mmiri nke cellulose ether na-adabere na ntinye mmiri nke isi, ihe mejupụtara nke ngwa agha, ọkpụrụkpụ nke ngwa agha, mkpa mmiri nke ngwa agha na oge nhazi nke ihe nhazi. Njide mmiri nke cellulose ether n'onwe ya sitere na solubility na akpịrị ịkpọ nkụ nke cellulose ether n'onwe ya.
N'ịchịkọta, na akọrọ-agwakọta ngwa agha njikere mix, hypromellose na-arụ ọrụ nke njide mmiri, ndim, retarding hydration ike nke ciment, na-emeziwanye ihe owuwu, wdg. Ikike ijide mmiri dị mma na-eme ka hydration ciment zuo oke, nwere ike imezi viscosity mmiri nke ngwa mmiri mmiri, meziwanye ike nke ngwa ngwa, nwere ike gbanwee oge. Mgbakwunye nke hypromellose nwere ike imeziwanye arụmọrụ ihe owuwu na ike nhazi nke ngwa agha ahụ. Ya mere, a na-eji cellulose ether eme ihe n'ọtụtụ ebe dị ka ihe mgbakwunye dị mkpa na ngwa ngwa agwakọta agwakọta akọrọ.
