02. Nchekwa methyl cellulose na elu okpomọkụ bụ ihe dị mkpa na-egosi iji chọpụta àgwà nke methyl cellulose ether. Ihe ndị dị ka okpomọkụ ikuku, ikuku ikuku na ọsọ ifufe na-emetụta mgbanwe nke ciment slurry na ngwaahịa gypsum. Ya mere, na-agbakwunye otu ego nke ngwaahịa HPMC n'oge dị iche iche, enwere ụfọdụ ọdịiche dị na nchekwa nchekwa mmiri. N'ime usoro ọrụ a kapịrị ọnụ, enwere ike idozi mmetụta nke moisturizing serosa site na ibelata ego nke HPMC agbakwunyere. Hydroxypropyl methylcellulose HPMC dị elu nwere ike dozie nsogbu nke njigide mmiri dị elu nke ọma.
Enwere ike kesaa methyl cellulose dị elu nke ọma na ngwa ngwa ciment na ngwaahịa plasta, na-akpụ ihe nkiri siri ike, nke ejiri nwayọ wepụta site na oyi akwa ma mepụta mmeghachi omume hydrophilic na akụrụngwa inorganic curling, si otú ahụ na-ahụ ike na ike. HPMC cellulose methyl propoxylate bụ qualitative na edo, na oxygen nke ethyl bromide na propionic acid dị iche iche tinyere molekul cellulose yinye bụ otu, nke na-eme ka oxygen na hydrogen bonding nke ọ bụla isi atọ nke hydroxyl na ether mmiri dị ala nwere ike tọghata free mmiri n'ime. mmiri na-azọpụta akpụkpọ anụ, si otú ahụ na-achịkwa ikuku mmiri nke ọma, na-emepụta okpomọkụ, na mmiri dị elu nke dabeere na mmiri.
N'ihi na a na-ewu ụlọ okpomọkụ dị elu n'oge okpomọkụ, iji nweta mmetụta nke ịzọpụta mmiri, ọ dị mkpa ịgbakwunye ngwaahịa HPMC dị elu dị ka usoro ahụ si dị, ma ọ bụghị ya, ọ ga-akpata nsogbu dị ka ihicha oke, ike dị ala, mgbawa, na-abaghị uru. ujo na nkwụsị, ma na-abawanye ihe isi ike nke ihe owuwu maka ndị ọrụ.
