Sodium carboxymethyl cellulose (CMC-Na maka nkenke) bụ ihe dị mkpa mmiri-soluble polymer compound na-eji ọtụtụ ebe na mmanụ olulu mmiri. Ngwongwo ya pụrụ iche na-eme ka ọ bụrụ ihe dị mkpa na usoro mmiri mmiri na-egwupụta ihe.
1. Ihe ndị bụ isi nke sodium carboxymethyl cellulose
Sodium carboxymethyl cellulose bụ anionic cellulose ether eme site cellulose mgbe alkali ọgwụgwọ na chloroacetic acid. Ọdịdị ya molekụla nwere ọnụ ọgụgụ buru ibu nke carboxymethyl otu, nke na-eme ka ọ nwee ezigbo mmiri solubility na nkwụsi ike. CMC-Na nwere ike ịmepụta ihe ngwọta dị elu na mmiri, na-eme ka ọkpụkpụ, nkwụsi ike na mmepụta ihe nkiri.
2. Ngwa nke sodium carboxymethyl cellulose na mkpọpu mmiri mmiri
Ọkpụrụkpụ
A na-eji CMC-Na eme ihe dị ka onye na-agba mmiri na mmiri mmiri. Isi ọrụ ya bụ ịbawanye viscosity nke mmiri mmiri na-egwupụta ihe ma welie ikike ya ibu mkpọ nkume na mkpọpu osisi. Viscosity kwesịrị ekwesị nke mmiri na-egwupụta ihe nwere ike igbochi mgbidi nke ọma nke ọma ma nọgide na-enwe nkwụsi ike nke olulu mmiri ahụ.
Mbelata mmiri mmiri
N'oge a na-egwupụta mmiri, mmiri mmiri ga-abanye n'ime oghere nke nhazi ahụ, na-eme ka mmiri na-efunahụ mmiri na-ekpo ọkụ, nke na-eme ka ọ bụghị nanị na-eme ka mmiri na-ekpo ọkụ na-ekpochapụ, ma nwekwara ike ime ka mgbidi mgbidi na-emebi emebi. Dị ka a ọmụmụ ọnwụ reducer, CMC-Na nwere ike na-etolite a ok iyo achicha na olulu mmiri mgbidi, n'ụzọ dị irè mbenata filtration ọnwụ nke mkpọpu mmiri mmiri na-echebe guzobe na olulu mmiri.
Mmanu mmanu
N'oge a na-egwupụta ihe, esemokwu dị n'etiti ihe ọkụkụ na mgbidi olulu mmiri ga-eme ka ọ dịkwuo ọkụ, na-eme ka ọkpụkpụ na-ebuwanye ibu nke ngwá ọrụ ahụ. Mmanya nke CMC-Na na-enyere aka ibelata esemokwu, belata iyi ngwá ọrụ a na-egwupụta ihe, ma melite arụmọrụ mkpọpu.
Stabilizer
Mmiri ịkwọ ụgbọ mmiri nwere ike ịfesa ma ọ bụ mebie n'okpuru oke okpomọkụ na nrụgide dị elu, si otú a tụfuo ọrụ ya. CMC-Na nwere ezigbo nkwụsi ike nke okpomọkụ na nguzogide nnu, ma nwee ike ịnọgide na-enwe nkwụsi ike nke mmiri mmiri n'okpuru ọnọdụ siri ike ma gbasaa ndụ ọrụ ya.
3. Usoro ọrụ nke sodium carboxymethyl cellulose
Ndozi viscosity
Ọdịdị molekụla nke CMC-Na nwere ọnụ ọgụgụ buru ibu nke otu carboxymethyl, nke nwere ike ịmepụta njikọ hydrogen na mmiri iji mee ka viscosity nke ngwọta dị elu. Site n'ịgbanwe ịdị arọ nke molekụla na ngbanwe nke CMC-Na, enwere ike ịchịkwa viscosity nke mmiri mmiri na-egwupụta ihe iji gboo mkpa nke ọnọdụ mkpọpu dị iche iche.
Njikwa nzacha
CMC-Na ụmụ irighiri ihe nwere ike na-etolite a atọ akụkụ netwọk Ọdịdị na mmiri, nke nwere ike na-etolite a ok iyo achicha na olulu ọma mgbidi na ibelata filtration ọnwụ nke mkpọpu mmiri mmiri. Nhazi nke achicha nzacha na-adabere ọ bụghị naanị na ntinye nke CMC-Na, kamakwa na ịdị arọ ya na ogo mgbanwe ya.
mmanu mmanu
CMC-Na ụmụ irighiri ihe nwere ike adsorbed n'elu nke akuakuzinwo bit na olulu mmiri dị na mmiri na-etolite a lubricating film ma belata esemokwu ọnụọgụ. Tụkwasị na nke ahụ, CMC-Na nwekwara ike ibelata esemokwu n'etiti oghere na mgbidi olulu mmiri site n'ịgbanwe viscosity nke mmiri mmiri.
Nkwụsi ike okpomọkụ
CMC-Na nwere ike ịnọgide na-enwe nkwụsi ike nke ihe owuwu molekụla ya n'okpuru ọnọdụ okpomọkụ dị elu ma ọ dịghị enwe ike imebi okpomọkụ. Nke a bụ n'ihi na ndị otu carboxyl dị n'ime ụmụ irighiri ya nwere ike ịmepụta njikọ hydrogen kwụsiri ike na ụmụ irighiri mmiri iji guzogide mmebi okpomọkụ. Na mgbakwunye, CMC-Na nwekwara ezigbo nguzogide nnu ma nwee ike ịnọgide na-arụ ọrụ ya na nhazi saline.
4. Ngwa Ihe atụ nke Sodium Carboxymethyl Cellulose
N'ime usoro ịgbapu mmiri n'ezie, mmetụta ntinye nke sodium carboxymethyl cellulose dị ịrịba ama. Dịka ọmụmaatụ, n'ime ọrụ ịkụ ala miri emi, a na-eji usoro mmiri mmiri nke nwere CMC-Na mee ihe iji chịkwaa nkwụsi ike na nkwụsị nke nzacha nke olulu mmiri ahụ nke ọma, mee ka ngwa ngwa na-egwupụta ihe, ma belata ụgwọ ọrụ. Tụkwasị na nke ahụ, a na-ejikwa CMC-Na eme ihe n'ọtụtụ ebe n'ịgba mmiri, na ezigbo nnu na-eguzogide ya na-eme ka ọ rụọ ọrụ nke ọma na gburugburu mmiri.
Ngwa nke sodium carboxymethyl cellulose n'ime mmiri na-egwupụta ihe na-agụnye akụkụ anọ: mbelata, ibelata mmiri na-efunahụ, mmanu na nkwụsi ike. Njirimara anụ ahụ na kemịkalụ ya pụrụ iche na-eme ka ọ bụrụ ihe dị mkpa na sistemu mmiri mmiri. Site na mmepe teknụzụ na-aga n'ihu na-aga n'ihu, atụmanya ngwa nke sodium carboxymethyl cellulose ga-aba ụba. N'ime nyocha n'ọdịnihu, enwere ike ịhazi usoro ihe omimi na ụzọ mgbanwe nke CMC-Na iji meziwanye arụmọrụ ya yana gboo mkpa gburugburu ebe igwu mmiri dị mgbagwoju anya.
