Carboxymethyl cellulose (CMC) bụ polymer molekụla dị elu nke a na-ejikarị eme ihe n'ịgba mmiri na-enwe ezigbo rheological Njirimara na nkwụsi ike. Ọ bụ cellulose gbanwetụrụ, nke a na-etolite site na imeghachi cellulose na chloroacetic acid. N'ihi arụmọrụ ya dị mma, a na-eji CMC eme ihe n'ọtụtụ ebe dị ka ịkụ ala mmanụ, ngwuputa ihe, ihe owuwu na ụlọ ọrụ nri.
1. Ngwongwo nke CMC
Carboxymethyl cellulose bụ ọcha na-acha odo odo ntụ ntụ nke na-etolite ngwọta colloidal transperent mgbe agbazere na mmiri. Ọdịdị kemịkal ya nwere otu carboxymethyl, nke na-eme ka ọ nwee ezigbo hydrophilicity na mmanu. Tụkwasị na nke ahụ, viscosity nke CMC nwere ike ịchịkwa site n'ịgbanwe ịdị arọ ya na ntinye uche ya, nke na-eme ka ngwa ya na-egwupụta mmiri na-agbanwe agbanwe.
2. Ọrụ na-egwupụta mmiri mmiri
N'oge a na-egwupụta mmiri, ịrụ ọrụ nke mmiri mmiri dị mkpa. CMC na-arụ ọrụ ndị a bụ isi n'ịgba mmiri:
Thickener: CMC nwere ike ịbawanye viscosity nke mmiri mmiri na-egwupụta mmiri, si otú ahụ na-eme ka ikike ibu ha dịkwuo elu, na-edebe ihe ndị siri ike kwụsịtụrụ, na igbochi sedimentation.
Rheology modifier: Site n'ịgbanwe ihe rheological Njirimara nke mmiri na-egwupụta mmiri, CMC nwere ike imeziwanye mmiri ya ka o wee nwee ike ịnọgide na-enwe ezigbo mmiri n'okpuru okpomọkụ dị elu na ọnọdụ nrụgide dị elu.
Plug agent: CMC ahụ nwere ike mejupụta mgbape nkume, belata mfu mmiri nke ọma ma melite arụmọrụ mkpọpu.
Mmanya: Mgbakwunye nke CMC nwere ike ibelata esemokwu n'etiti ihe ọkụkụ na mgbidi olulu mmiri, belata iyi ma na-abawanye ngwa ngwa.
3. Uru nke CMC
Iji carboxymethyl cellulose dị ka ihe mgbakwunye mmiri na-egwu mmiri nwere uru ndị a:
Enyi na gburugburu ebe obibi: CMC bụ ihe eji eme polymer nke nwere ezigbo biodegradability na obere mmetụta na gburugburu ebe obibi.
Ọnụ ahịa bara uru: E jiri ya tụnyere polymers synthetic ndị ọzọ, CMC nwere ọnụ ala dị ala, arụmọrụ magburu onwe ya na ọnụ ahịa dị elu.
Okpomọkụ na salinity mgbanwe: CMC ka nwere ike ịnọgide na-arụ ọrụ kwụsiri ike na oke okpomọkụ na nnukwu nnu gburugburu yana ime mgbanwe n'ụdị ọnọdụ ala dị iche iche.
4. Ihe atụ ngwa
N'ime ngwa n'ezie, ọtụtụ ụlọ ọrụ mmanụ ejirila CMC mee ihe nke ọma n'ọrụ ịkụ ala dị iche iche. Dịka ọmụmaatụ, na ụfọdụ nnukwu okpomọkụ na olulu mmiri dị elu, na-agbakwunye CMC kwesịrị ekwesị nwere ike ịchịkwa rheology nke apịtị ahụ nke ọma ma hụ na ịkụ ala dị mma. Na mgbakwunye, n'ụdị ụfọdụ dị mgbagwoju anya, iji CMC dị ka ihe nkwụnye ọkụ nwere ike belata mfu mmiri ma melite arụmọrụ mkpọpu.
5. Akpachara anya
Ọ bụ ezie na CMC nwere ọtụtụ uru, a ga-ahụkwa isi ihe ndị a n'oge eji:
Oke: Gbanwee ego nke CMC agbakwunyere dabere na ọnọdụ n'ezie. Iji oke eme ihe nwere ike ibute mbelata mmiri mmiri.
Ọnọdụ nchekwa: Ekwesịrị idobe ya na ebe kpọrọ nkụ ma dị jụụ iji zere mmiri na-emetụta arụmọrụ.
Ịgwakọta nke ọma: Mgbe ị na-akwadebe mmiri mmiri na-egwupụta ihe, hụ na CMC agbazere n'ụzọ zuru ezu iji zere nchịkọta urughuru.
Ngwa nke carboxymethyl cellulose na mmiri mmiri na-egwupụta ọ bụghị nanị na-eme ka nrụpụta ọrụ dị mma ma na-ebelata ụgwọ ọrụ, ma na-akwalite mmepe nke teknụzụ nchebe gburugburu ebe obibi ruo n'ókè ụfọdụ. Site na ọganihu nke sayensị na nkà na ụzụ, a ga-agbasawanye ngwa ngwa nke CMC, anyị na-atụkwa anya ikere òkè dị ukwuu na ọrụ ịkụ ala n'ọdịnihu.
