Hydroxypropyl Methylcellulose (HPMC) bụ ihe a na-ejikarị eme ihe na mmiri na-agbaze mmiri nke a na-ejikarị eme ihe na ihe owuwu ụlọ, mkpuchi, ọgwụ, nri na ubi ndị ọzọ. Na mmepụta ciment, a na-ejikarị HPMC eme ihe. Ọrụ ya pụrụ iche na njirimara dị elu na-eme ka ọ bụrụ ihe mgbakwunye dị mkpa na ngwaahịa ciment.
1. Melite arụmọrụ na ịrụ ọrụ ihe owuwu
HPMC nwere ike melite arụmọrụ nke ngwakọta ciment. N'ime usoro mmepụta ciment, mmiri mmiri na ịdị n'otu nke ngwakọta bụ ihe ndị dị mkpa na-emetụta àgwà ụlọ. HPMC nwere ezi dispersion na ndim Njirimara na mmiri, na-eme ka ciment slurry mfe ịkpali, wụsa na-eji ire ụtọ n'oge ewu. Nke a na-emeziwanye ọ bụghị nanị na-eme ka arụmọrụ nke ihe owuwu dịkwuo mma, ma na-ebelata ọgbọ nke egosipụta ma na-eme ka compactness na n'ozuzu àgwà nke ihe.
2. Meziwanye njigide mmiri
HPMC nwere ezigbo njide mmiri ma nwee ike ibelata evaporation mmiri nke ọma. Nke a dị oke mkpa maka usoro ọgwụgwọ nke ngwaahịa ciment. Simenti chọrọ mmiri zuru oke maka mmeghachi omume hydration n'oge usoro ọgwụgwọ, na iji HPMC nwere ike ịgbatị oge njigide mmiri nke ciment slurry ma hụ na mmiri nwere ike ịbanye n'ime akụkụ ciment nke ọma, si otú a na-eme ka ike na ịdịte aka nke ciment dịkwuo mma. Karịsịa na ọnọdụ okpomọkụ dị elu ma ọ bụ ikuku na-ekpochapụ, arụmọrụ njigide mmiri nke HPMC dị mkpa karịsịa.
3. Meziwanye nkwụsị mgbape
Na mmepụta na iji ngwaahịa ciment mee ihe, ihe na-eme nke mgbawa bụ nsogbu nkịtị. The ojiji nke HPMC nwere ike n'ụzọ dị irè ibelata omume nke cracks. N'ihi njide mmiri ya dị mma, HPMC nwere ike ibelata ihicha ihicha nke ikuku mmiri na-akpata, si otú ahụ belata ihe ize ndụ nke mgbawa na-akpata site na shrinkage. Na mgbakwunye, HPMC nwekwara ike na-etolite a edo netwọk Ọdịdị na simenti matriks, dịkwuo ike na mgbawa nguzogide nke ihe, na melite n'ozuzu anwụ ngwa ngwa.
4. Meziwanye adhesion
HPMC nwere ike ịkwalite ike njikọ dị n'etiti ciment na mkpụrụ. Karịsịa mgbe ị na-eji ihe ntụ ntụ, ihe ndị na-agbapụta agba nke HPMC nwere ike melite nrapado nke ciment slurry nke ọma. Maka ngwa nke adhesives tile, gypsum na ihe ndị ọzọ na-ewu ụlọ, HPMC nwere ike hụ na njikọ siri ike n'etiti ihe, gbochie oghere na ịdaba, ma hụ na ọ dị mma.
5. Melite mmegharị na ịrụ ọrụ
Mgbakwunye nke HPMC nwere ike imeziwanye mmiri nke ciment slurry nke ọma, na-eme ka ngwakọta ahụ gbasaa ma dị mfe ịmepụta n'oge a na-ewu ụlọ. Karịsịa n'ime usoro nwere ọdịnaya dị elu, HPMC nwere ike belata viscosity nke ngwakọta ma melite mmiri mmiri ya, si otú ahụ meziwanye mma nke ihe owuwu. Nke a dị mkpa karịsịa na nnukwu ihe owuwu, nke nwere ike imeziwanye arụmọrụ na ịdị mma nke ihe owuwu.
6. Ike mgbanwe
HPMC nwere nnukwu mgbanwe yana dakọtara na ụdị ciment dị iche iche na mgbakwunye ndị ọzọ. Ma ọ bụ ciment Portland nkịtị, ciment siri ike ngwa ngwa, ma ọ bụ ciment pụrụ iche, HPMC nwere ike ịrụpụta uru ya nke ọma. Na mgbakwunye, HPMC nwekwara ike iji ya na mgbakwunye kemịkalụ ndị ọzọ (dị ka ihe na-eme ka ikuku ikuku, ihe na-ebelata mmiri, wdg) iji kwalite arụmọrụ kọmpụta zuru oke ma gboo mkpa ihe owuwu dị iche iche.
7. Meziwanye ike
Ngwaahịa ciment na-eji HPMC nwere ọmarịcha anwụ ngwa ngwa. HPMC nwere ike igbochi ịka nká na mmebi nke mkpụrụ simenti ma melite nguzogide acid na alkali, nguzogide mmiri, na nguzogide ifriizi. Site n'ibelata mfu mmiri, HPMC na-ahụ na ciment nwere ike meghachi omume n'ụzọ zuru ezu n'oge usoro hydration, na-eme ka ike dịkwuo elu na ogologo oge. Nke a dị mkpa maka iji ogologo oge na nhazi nke ihe owuwu ụlọ.
8. Green na gburugburu ebe obibi enyi
Dị ka a eke polymer ihe, HPMC nwere ezi gburugburu ebe obibi nchedo Njirimara. A gaghị ahapụ ihe ndị na-emerụ ahụ n'oge mmepụta na ojiji ya, ọ na-emezukwa ihe achọrọ nke ụlọ akwụkwọ ndụ akwụkwọ ndụ nke oge a. Site na mmụba na-aga n'ihu nke ihe nchebe gburugburu ebe obibi chọrọ na ụlọ ọrụ ihe owuwu, ngwa nke HPMC enwetawo nlebara anya karị. Ngwaahịa ciment na-eji HPMC na-arụ ọrụ dị elu ma na-enye aka na nchekwa gburugburu ebe obibi.
9. Ọnụ-erite uru
Ọ bụ ezie na ọnụ ahịa nke HPMC na mmepụta dị oke elu, ọtụtụ uru ọ na-eweta nwere ike ibelata ojiji nke mgbakwunye ndị ọzọ nke ọma, si otú a na-ebuli ọnụ ahịa niile. Na mgbakwunye, iji HPMC nwere ike imeziwanye arụmọrụ ihe owuwu ma belata oge owuwu, si otú a na-ebelata ụgwọ ọrụ. N'ozuzu, ngwa nke HPMC nwere ike ime n'ụzọ akụ na ụba.
HPMC nwere ọtụtụ uru na ciment mmepụta, gụnyere mma operability, mmiri njigide, mgbape na-eguzogide, adhesion, fluidity, wdg Ndị a àgwà na-eme ka HPMC ihe dị oké mkpa mmako na ọgbara ọhụrụ ciment mmepụta. Dị ka ụlọ ọrụ ihe owuwu chọrọ maka ịrụ ọrụ ihe na-aga n'ihu, ngwa nke HPMC ga-abawanye ụba, na-akwalite mmepe nke ngwaahịa ciment n'ụzọ dị elu na nchebe gburugburu ebe obibi.
