Ngwa agha na-edobe onwe ya nwere ike ịdabere n'ịdị arọ nke ya iji guzobe ntọala dị larịị, dị nro na nke siri ike na mkpụrụ maka ịtọọ ma ọ bụ jikọta ihe ndị ọzọ, ma nwee ike ịrụ nnukwu ihe owuwu na nke ọma. Ya mere, elu fluidity bụ nnọọ ịrịba akụkụ nke onwe larịị ngwa agha; Tụkwasị na nke ahụ, ọ ga-enwekwa ogo nke njide mmiri na ike njikọ, na-enweghị ihe omume nke nkewa mmiri, ma nwee njirimara nke mkpuchi na ịrị elu okpomọkụ dị ala. N'ozuzu, ngwa agha na-ebuli onwe ya na-achọ ezigbo mmiri, ma n'ezie fluidity nke ciment slurry na-abụkarị naanị 10-12cm; Cellulose ether bụ ihe mgbakwunye bụ isi n'ime ngwa agha agwakọtara agwakọta. Ọ bụ ezie na ego agbakwunyere dị ntakịrị, ọ nwere ike imeziwanye arụmọrụ nke ngwa agha ahụ. Ọ nwere ike imeziwanye nkwụsi ike, ịrụ ọrụ, ịrụ ọrụ njikọ, na njigide mmiri nke ngwa agha ahụ. Ọ na-arụ ọrụ dị oke mkpa n'ọhịa nke ngwa ngwa agwakọta.

1. Mmiri mmiri
Cellulose ether nwere mmetụta dị ukwuu na njide mmiri, nkwụsi ike, na ịrụ ọrụ nke ngwa agha na-edo onwe ya. Karịsịa dị ka ngwa agha na-ebuli onwe ya elu, ịgbasa mmiri bụ otu n'ime ihe ndị bụ isi na-egosi iji nyochaa arụmọrụ nke onwe. N'ihe gbasara ijide n'aka na ihe mejupụtara nke ngwa agha ahụ dị, enwere ike ịhazigharị mmiri nke ngwa agha ahụ site n'ịgbanwe usoro nke cellulose ether. Otú ọ dị, ịṅụbiga mmanya ókè nwere ike ibelata mmiri mmiri nke ngwa agha ahụ, ya mere ekwesịrị ịchịkwa usoro nke cellulose ether n'ime oke ezi uche.

2. Njide mmiri
Njide mmiri nke ngwa agha bụ ihe dị mkpa iji tụọ nkwụsi ike nke ihe dị n'ime nke ngwa ciment agwakọtara ọhụrụ. Iji mee ka ihe gel na-eme ka mmiri dị n'ụzọ zuru ezu, ihe ezi uche dị na ya nke cellulose ether nwere ike ịnọgide na-enwe mmiri na ngwa ngwa ruo ogologo oge. N'ikwu okwu n'ozuzu, ọnụ ọgụgụ njide mmiri nke slurry na-abawanye site na mmụba nke cellulose ether ọdịnaya. Mmetụta njide mmiri nke cellulose ether nwere ike igbochi mkpụrụ ahụ ka ọ ghara ịmịnye mmiri nke ukwuu ma ọ bụ ngwa ngwa, na-egbochi ikuku mmiri, si otú ahụ hụ na ebe slurry na-enye mmiri zuru oke maka hydration ciment. Na mgbakwunye, viscosity nke cellulose ether nwekwara mmetụta dị ukwuu na njide mmiri nke ngwa agha. Nke dị elu nke viscosity, ka mma na-ejigide mmiri. Cellulose ether nwere viscosity izugbe nke 400mpa. s ka a na-ejikarị eme ihe na ngwa agha na-ebuli onwe ya, nke nwere ike imeziwanye arụmọrụ ọkwa na mkpirisi nke ngwa agha ahụ.
