N'ime ngwa agha agwakọtara agwakọta, mgbakwunye cellulose ether dị ntakịrị, mana ọ nwere ike melite arụmọrụ ngwa agha mmiri, nke bụ nnukwu mgbakwunye na-emetụta arụmọrụ nke ngwa agha. Ọrụ dị mkpa nke HPMC na ngwa agha bụ isi n'akụkụ atọ, otu bụ ikike njigide mmiri dị mma, nke abụọ bụ mmetụta na nkwụsi ike ngwa ngwa, nke atọ bụ mmekọrịta na ciment.
1. Ihe ka ukwuu nke viscosity nke cellulose ether, ka mma na-arụ ọrụ njigide mmiri.
2. Ka ọnụ ọgụgụ dị ukwuu nke cellulose ether na-agbakwunye na ngwa agha, ka mma na-arụ ọrụ njigide mmiri.
3. N'ihi na urughuru size, mma urughuru, mma na-ejigide mmiri.
4. Mkpuchi mmiri nke methyl cellulose ether na-ebelata na mmụba nke okpomọkụ.
Mmetụta siri ike nke hydroxypropyl methyl cellulose dị ka thickener metụtara nha nha, viscosity na mgbanwe nke hydroxypropyl methyl cellulose. N'ikwu okwu n'ozuzu, ka viscosity nke cellulose ether dị elu, nke nta nke nta nke nta ahụ, ka ọ na-apụta ìhè na mmetụta na-agbapụta.
Ọrụ nke atọ nke cellulose ethers bụ ịkwụsị usoro hydration nke ciment. Cellulose ethers na-enye ngwa agha dị iche iche bara uru ma na-ebelata mmalite nke hydration okpomọkụ ntọhapụ nke ciment ma na-akwụsị usoro ike hydration nke ciment. N'ịdị elu nke cellulose ether na ihe gel ịnweta, otú ahụ ka mmetụta nke hydration na-egbu oge na-apụta ìhè karị. Cellulose ethers ọ bụghị nanị na ọ na-eweghachite ntọala ahụ, kamakwa ọ na-egbu oge usoro siri ike nke simenti ngwa ngwa. Site na mmụba nke ọgwụ HPMC, nhazi oge nke ngwa agha mụbara nke ukwuu.
Na nchịkọta, na ngwa ngwa agwakọta dị njikere, HPMC na-arụ ọrụ nke njide mmiri, ịgbatị, na-egbu oge ike hydration nke ciment na imeziwanye arụmọrụ ihe owuwu. Ikike njide mmiri dị mma na-eme ka hydration ciment zuo oke, nke nwere ike ime ka mgbochi mmiri nke mmiri mmiri dịkwuo elu ma mee ka njikọ nke ngwa agha dịkwuo elu. Ya mere, a na-eji HPMC eme ihe n'ọtụtụ ebe dị ka ihe mgbakwunye dị mkpa n'ime ngwa agha agwakọtara agwakọta.
