Arụmọrụ:
1. A na-eji hydroxypropyl methyl cellulose eme ihe n'ụdị ngwa agha niile gụnyere ngwa agha nkume, ngwa agha plastering na ngwa agha nhazi iji melite ọbara ọgbụgba nke ngwa agha.
2. hydroxypropyl methyl cellulose nwere mmetụta nke ịdị arọ, na-eme ka arụmọrụ owuwu na arụmọrụ nke ngwa agha ahụ ka mma, ma na-eme ka saturation na olu nke ngwa agha ahụ ka mma.
3. hydroxypropyl methyl cellulose nwere ike ime ka ngwa agha ahụ dịkwuo mma ma rụọ ọrụ nke ọma, ma merie ntụpọ nkịtị nke ngwa agha nkịtị dịka ịkpụ shei na oghere.
4. hydroxypropyl methyl cellulose nwere mmetụta na-egbochi ihe, nke nwere ike ijide n'aka na ngwa agha ahụ na-ewe oge ma melite mmetụta owuwu nke ngwa agha ahụ.
5. Hydroxypropyl methyl cellulose nwere ike iweta ọnụọgụ afụ kwesịrị ekwesị, nwere ike ime ka ntu oyi na-eguzogide ngwa ngwa, na ogologo oge ngwa agha dịkwuo elu.
6. Hydroxypropyl methyl cellulose bụ njikọta nke mmetụta anụ ahụ na kemịkalụ iji rụọ ọrụ na njigide mmiri na oke, na usoro mmiri nwere ike ibute obere mgbasawanye nke ihe ahụ, si otú a ngwa agha nwere oke obere mgbasawanye, a na-egbochi mgbawa nke mkpụkọ nke ngwa agha kpatara na usoro mmiri mmiri emechara, a na-emekwa ka ndụ ọrụ nke ụlọ ahụ dịkwuo elu.
Ụzọ Ojiji
1. Oke moto akwadoro nke moto M10 bụ: simenti: ntụ ntụ: ájá = 120:80:800 (ọ bụrụ na ejirighị ntụ ntụ, a ga-eji simenti dochie ọnụọgụ ntụ ntụ). Ọdịnaya nke cellulose ether bụ 0.5 ~ 1.0% nke moto niile.
2. Dịka e si tụọ simenti na ájá dị mma, wee tinye ihe e ji eme ihe nke cellulose ether, n'ebe a na-ewu ụlọ dịka e si kwuo na ojiji mmiri na-agwakọta ya.
3. Ụzọ ngwakọta nke ngwa agha: nke mbụ, a tụrụ mmiri n'ime akpa ahụ, wee tinye ngwa agha ahụ n'ime akpa ahụ maka ịgwakọta ya.
4. A na-agwakọta ngwa agha a gwakọtara ya na cellulose ether nke ụrọ n'ụzọ igwe. Oge ngwakọta ahụ na-amalite site na nkeji 3-5 mgbe etinyechara ihe ahụ n'ime ụrọ ahụ. 5. A ga-agwakọta ngwa agha ahụ na ojiji ya, a na-emekarị ya n'ime awa 4 mgbe agwakọtara ya, mgbe okpomọkụ n'oge owuwu ihe karịrị 30 Celsius C ga-adịrịrị n'ime awa 3 mgbe agwakọtara ya.
