02. Nchekwa methyl cellulose na okpomọkụ dị elu bụ ihe ngosi dị mkpa iji chọpụta ịdị mma nke methyl cellulose ether. Ihe ndị dị ka okpomọkụ ikuku, okpomọkụ ikuku na ọsọ ifufe na-emetụta mgbanwe nke ngwaahịa simenti slurry na gypsum. Ya mere, site na itinye otu ọnụọgụ ngwaahịa HPMC n'oge dị iche iche, enwere ọdịiche ụfọdụ na arụmọrụ nchekwa mmiri. N'ime usoro ọrụ akọwapụtara, enwere ike idozi mmetụta nke moisturizing serosa site na ibelata ọnụọgụ HPMC agbakwunyere. hydroxypropyl methylcellulose HPMC dị elu nwere ike idozi nsogbu nke nchekwa mmiri dị elu nke ọma.
Enwere ike kesaa methyl cellulose dị elu nke ọma n'ụzọ dị mfe na nke ọma na simenti na ngwaahịa plastering, na-emepụta ihe nkiri siri ike, nke a na-ewepụta nwayọ nwayọ site na oyi akwa isi ma na-emepụta mmeghachi omume hydrophilic site na ihe ndị na-adịghị agbanwe agbanwe, si otú a na-ahụ na ike na ike dị. HPMC cellulose methyl propoxylate dị mma ma dịkwa otu, oxygen nke ethyl bromide na otu propionic acid dị n'akụkụ yinye cellulose molecular dịkwa otu, nke na-eme ka njikọ oxygen na hydrogen nke atọm isi ọ bụla nke hydroxyl na ether dịkwuo mma.
