N'ozuzu, ngwa ngwa na-ahụ maka onwe ya chọrọ mmiri mmiri, mana mmiri ciment n'ezie n'ezie na-abụkarị naanị 10-12cm; N'ime usoro okike cell, hydroxypyl methylcellose (hpmc) bụ ihe mgbakwunye ahụ dị ala, ọ nwere ike ime ka arụmọrụ nke ngwa agha, ọ nwere ike melite agbanwe agbanwe, arụmọrụ ọrụ na njikọta mmiri na-arụ ọrụ nke ngwa agha. Ọ na-arụ ọrụ dị oke mkpa n'ọhịa ngwa ngwa.
1. Mongy
Hydroxypyl Methylcellose (hpmc) nwere mmetụta dị mkpa na njigide mmiri, na-agbanwe agbanwe na arụmọrụ nke ngwa agha. Karịsịa dị ka ngwa agha nke onwe, ọnya bụ otu n'ime ihe ndị bụ isi maka inyocha arụmọrụ onwe ya. N'okpuru mbu na-agba mbọ ka usoro ihe mejupụtara nke ngwa agha ahụ, a ga-agbanwe nke ngwa agha site na ịgbanwe ego HPMC. Agbanyeghị, ọ bụrụ na usoro ọgwụgwọ dị oke elu, a ga-ebelata ọnya nke ngwa agha, yabụ na ị ga-achịkwa hpmc n'ime ezi uche dị na ya.
2. Njide mmiri
Njikọ mmiri nke ngwa agha bụ ndeksi dị mkpa iji tụọ nkwụsi ike nke ihe mejupụtara nke oghere ciment. Iji mepụta mmeghachi omume hydration nke Gel ihe, nke ezi uche dị na HPMC nwere ike ịnọgide na-enwe mmiri ahụ na ngwa agha ruo ogologo oge. N'ikwu okwu n'ozuzu, mmiri mgbochi mmiri nke slurry na-abawanye na mmụba nke ọdịnaya HPMC. Arụ ọrụ n 'mgbochi mmiri nke HPMC nwere ike igbochi mkpụrụ site na ịmịnye mmiri ngwa ngwa, ma na-egbochi mmiri mmiri, iji hụ na gburugburu ebe a na-enye mmiri hydration. Na mgbakwunye, viscosity hydroxypropyythylthylcellose nwekwara nnukwu mmetụta na mmiri iji mmiri. Nnọọ dị elu na viscosity, ka mma njigide mmiri. N'ozuzu, ngwaahịa na viscosity nke ihe dị ka 400MPA.S maka ngwa agha nke onwe, nke nwere ike ime ka arụmọrụ nke ngwa agha ma bulie ngwa ngwa nke ngwa agha.
3. Ebe a na-edebe oge
HPMC nwere ụfọdụ na-arụ ọrụ na ngwa agha. Site na mmụba nke usoro ọgwụgwọ, oge nrụpụta nke ngwa agha na-adị ogologo. Mmetụta na-akwụ ụgwọ nke HPMC na ciment pastema na-adabere na ogo nke otu Alkyl, ma nwee obere mmekọrịta na oke molecular ya. Obere obere nke Alkyl nbanye, na-ebuwanye ọdịnaya hydroxy, na nsonaazụ doro anya karị. Ma dị elu na-ahụ maka ihe dị na HPMC ọdịnaya, ihe doro anya na mmetụta nke ihe nkiri dị mgbagwoju anya oyi akwa na mbido hyderation nke ciment, yabụ mmetụta azụta na-apụtakwa ìhè karị.

Ọtụtụ mgbe, ike bụ otu n'ime ihe dị mkpa atụmatụ nyocha maka mmetụta nke ciment ciment ciment na ngwakọta. Ike ike na ike na-eme ka mmụba nke ọdịnaya HPMC ga-belata.
5. Bong Ike
HPMC nwere ezigbo mmetụta na njikọta nke ngwa agha. HPMC na-etolite ihe nkiri polymer na-eme ka ọ dị n'etiti usoro mmiri mmiri na ciment hydration, nke na-eme ka ọfụma nke ciment, nke si otú ahụ na-eme ka ọ dị mma. Ike nke ha. N'otu oge ahụ, ịgbakwunye ego HPMC kwesịrị ndụ na ngbanwe nke ngwa agha, na-ebelata ike nke mpaghara ntụgharị n'etiti ngwa agha, ma na-ebelata ikike ndị dị n'etiti etiti. Nye otu oge, mmetụta nke njikọ dị n'etiti ngwa agha na mkpụrụ a kụrụ. Na mgbakwunye, n'ihi ịdị adị nke HPMC na ciment na mpaghara mgbanwe pụrụ iche na akwa interface a na-guzobere n'etiti ngwakọ na ngwaahịa hydration. Oyi interface na-eme ka interface Mpaghara na-agbanwe agbanwe ma na-adịghị ala. Ya mere, ihe ọkụkụ ahụ nwere ike nke ji sie ike.
