Umphumela Wokunamathela
Ukunamathela kwe-CMC ku-slurry kubangelwa ukwakhiwa kwesakhiwo senethiwekhi eqinile ngamabhondi e-hydrogen namandla e-van der Waals phakathi kwama-macromolecules.Lapho amanzi engena ebhulokhini le-CMC, amaqembu e-hydrophilic angadonsi amanzi amancane ayavuvukala, kuyilapho lawo angama-hydrophilic amaningi ahlukana ngokushesha ngemva kokuvuvukala.Amaqembu e-hydrophilic e-inhomogeneous ekukhiqizeni kwe-CMC aphumela kusayizi wezinhlayiyana ezihlakazekile ezihlukene zama-micelles.Ukuvuvukala kwe-hydration kwenzeka ngaphakathi kwama-micelles, okwenza ungqimba lwamanzi aboshwe ngaphandle.Esigabeni sokuqala sokuqedwa, ama-micelles akhululekile ku-colloid.Amandla e-van der Waals ahlanganisa kancane kancane ama-micelles, futhi ungqimba lwamanzi abophekile lwakha isakhiwo senethiwekhi ngenxa ye-asymmetry yosayizi nokuma.Isakhiwo senethiwekhi ye-CMC ene-fibrous sinevolumu enkulu, ukunamathela okuqinile, futhi kunciphisa amaphutha acwebezelayo.
Levitation Effect
Ngaphandle kwezithasiselo, i-glaze slurry izozinza ngenxa yamandla adonsela phansi ngokuhamba kwesikhathi, futhi ukwengeza inani elithile lobumba akwanele ukuvimbela lokhu ukuthi kungenzeki.Kodwa-ke, ukungezwa kwenani elithile le-CMC kungakha isakhiwo senethiwekhi esisekela amandla adonsela phansi ama-molecule acwebezelayo.Ama-molecule e-CMC noma ama-ion anwebeka kucwebezela futhi athathe isikhala, avimbele ukuthintana kwama-molecule acwebezelayo nezinhlayiyana, okuthuthukisa ukuzinza kwe-dimensional kwe-slurry.Ikakhulukazi, ama-anion e-CMC anecala elibi axosha izinhlayiya zobumba ezifakwe icala elibi, okuholela ekwandeni kokumiswa kwe-glaze slurry.Lokhu kusho ukuthi i-CMC inokumiswa okuhle ku-glaze slurry.Isakhiwo senethiwekhi esakhiwe yi-CMC siphinde sisiza ekwehliseni amaphutha acwebezelayo futhi siqinisekise ukuqedwa okubushelelezi.Sekukonke, i-CMC idlala indima ebalulekile ekuzinzeni nasekumisweni kwe-glaze slurry, okubalulekile ukuze kuzuzwe imiphumela engaguquki nekhwalithi ephezulu enqubweni yokucwebezela.
Imibuzo Okufanele Icatshangwe Lapho Ukhetha I-CMC
Ukusetshenziswa okufanele kwe-CMC ekukhiqizeni i-glaze kungathuthukisa kakhulu ikhwalithi yomkhiqizo wokugcina.Ukuqinisekisa umphumela omuhle kakhulu, kunamaphuzu ambalwa abalulekile okufanele alandelwe.Okokuqala, kubalulekile ukubheka ukucaciswa kwemodeli ye-CMC ngaphambi kokuthenga bese ukhetha imininingwane efanelekile yokukhiqiza.Uma ungeza i-CMC kucwebe ngesikhathi sokugaya, kungasiza ukuthuthukisa ukusebenza kahle kokugaya.Ukunakwa kufanele futhi kukhokhwe kusilinganiso samanzi ukuya ku-CMC lapho kuthelwa amanzi ukuze kuzuzwe umphumela omkhulu.
I-glaze slurry kufanele ivunyelwe ukubola usuku noma ezimbili ukuze kuqinisekiswe ukuthi izinzile ngokwanele futhi i-CMC ingadlala umphumela omuhle kakhulu.Kubalulekile futhi ukulungisa kahle inani le-CMC elingezwe ngokuya ngezinguquko zesizini, ngokwengezwa kakhulu ehlobo, okuncane kakhulu ebusika, kanye nebanga elingu-0.05% ukuya ku-0.1% phakathi.Uma umthamo ushiywe ungashintshiwe ebusika, ungabangela ukucwebezela okugijimayo, ukoma kancane, kanye nokucwebezela okunamathelayo.Ngokuphambene, umthamo onganele uzoholela endaweni ecwebezelayo eqinile.
Ehlobo, amazinga okushisa aphezulu angehlisa i-viscosity ye-CMC ngenxa yethonya lebhaktheriya.Ngakho-ke, kuyadingeka ukwenza umsebenzi we-anti-corrosion futhi wengeze izithasiselo ezifanele ukugcina ikhwalithi ye-CMC.Okokugcina, uma usebenzisa i-glaze, kunconywa ukuthi uyihlunge ngesisefo esingaphezu kwe-100 mesh ukuvimbela insalela ye-CMC ukuthi ithinte indawo ecwebezelayo ngesikhathi sokudubula.Ngokulandela le mihlahlandlela, i-CMC ingasetshenziswa ngempumelelo ekukhiqizweni kweglaze ukuthuthukisa ikhwalithi yomkhiqizo.
