Kugwiritsa ntchito kwa CMC mu Ceramic Glaze
Ceramic glaze ndi zokutira zamagalasi zomwe zimagwiritsidwa ntchito pazadothi kuti zikhale zokongoletsedwa bwino, zolimba, komanso zogwira ntchito. Chemistry ya ceramic glaze ndizovuta, ndipo zimafunikira kuwongolera moyenera magawo osiyanasiyana kuti mupeze zomwe mukufuna. Chimodzi mwazinthu zofunika kwambiri ndi CMC, kapena kuti micelle concentration, yomwe imagwira ntchito yofunika kwambiri pakupanga ndi kukhazikika kwa glaze.
CMC ndi kuchuluka kwa ma surfactants pomwe mapangidwe a micelles amayamba kuchitika. Micelle ndi kamangidwe kamene kamapanga pamene mamolekyu a surfactant aphatikizana pamodzi mu njira yothetsera, kupanga mawonekedwe ozungulira omwe ali ndi michira ya hydrophobic pakati ndi mitu ya hydrophilic pamwamba. Mu ceramic glaze, ma surfactants amakhala ngati dispersants omwe amalepheretsa kukhazikika kwa tinthu tating'onoting'ono ndikulimbikitsa kupanga kuyimitsidwa kokhazikika. CMC ya surfactant imatsimikizira kuchuluka kwa surfactant yofunikira kuti ikhale yokhazikika, yomwe imakhudzanso mtundu wa glaze.
Chimodzi mwazofala kwambiri za CMC mu ceramic glaze ndi ngati dispersant kwa ceramic particles. Tinthu tating'onoting'ono ta Ceramic timakhala ndi chizolowezi chokhazikika mwachangu, zomwe zingayambitse kugawa kosagwirizana komanso kusauka kwapamwamba. Ma dispersants amathandizira kuti asakhazikike popanga mphamvu yonyansa pakati pa tinthu tating'onoting'ono, tomwe timawapangitsa kuti asasunthike mu glaze. CMC ya dispersant imatsimikizira ndende yocheperako yofunikira kuti mukwaniritse kubalalitsidwa koyenera. Ngati ndende ya dispersant ndi yotsika kwambiri, tinthu tating'onoting'ono timakhazikika, ndipo glaze idzakhala yosiyana. Kumbali ina, ngati ndendeyo ili yokwera kwambiri, imatha kupangitsa kuti glaze ikhale yosakhazikika ndikugawanika kukhala zigawo.
Ntchito ina yofunika yaCMC mu ceramic glazeali ngati rheology modifier. Rheology imatanthawuza kuphunzira za kayendedwe ka zinthu, ndipo mu ceramic glaze imatanthawuza momwe glaze imayendera ndikukhazikika pamwamba pa ceramic. The rheology wa glaze amakhudzidwa ndi zinthu zosiyanasiyana, kuphatikizapo tinthu kukula kugawa, mamasukidwe akayendedwe a suspending sing'anga, ndi ndende ndi mtundu dispersant. CMC angagwiritsidwe ntchito kusintha rheology wa glaze ndi kusintha mamasukidwe akayendedwe ndi kuyenda katundu. Mwachitsanzo, dispersant yapamwamba ya CMC imatha kupanga glaze yamadzimadzi yomwe imayenda bwino komanso molingana pamwamba, pomwe dispersant ya CMC yotsika imatha kupanga glaze yokulirapo yomwe siyikuyenda mosavuta.
CMC itha kugwiritsidwanso ntchito kuwongolera kuyanika ndi kuwombera kwa ceramic glaze. Pamene glaze ikugwiritsidwa ntchito pamwamba pa ceramic, iyenera kuuma isanayambe kuyaka. Kuwumitsa kungakhudzidwe ndi zinthu zosiyanasiyana, kuphatikizapo kutentha ndi chinyezi cha chilengedwe, makulidwe a glaze wosanjikiza, ndi kupezeka kwa surfactants. CMC angagwiritsidwe ntchito kusintha kuyanika katundu wa glaze ndi kusintha mavuto padziko ndi mamasukidwe akayendedwe a suspending sing'anga. Izi zingathandize kupewa ming'alu, kupotoza, ndi zolakwika zina zomwe zingachitike panthawi yowumitsa.
Kuphatikiza pa ntchito yake monga dispersant and rheology modifier, CMC itha kugwiritsidwanso ntchito ngati binder mu ceramic glaze. Zomangira ndi zida zomwe zimagwirizanitsa tinthu tating'onoting'ono ta glaze ndikulimbikitsa kumamatira kumtunda wa ceramic. CMC imatha kukhala ngati chomangira popanga filimu yopyapyala pamwamba pa tinthu tating'onoting'ono ta ceramic, zomwe zimathandiza kuzigwirizanitsa pamodzi ndikulimbikitsa kumamatira. Kuchuluka kwa CMC kofunikira ngati chomangira kumatengera zinthu zosiyanasiyana, kuphatikiza kukula kwa tinthu ndi mawonekedwe, mawonekedwe a glaze, ndi kutentha kwamoto.
Pomaliza, ma CMC) amagwira ntchito yofunika kwambiri popanga glaze ya ceramic.
