Adhesion Zotsatira
The adhesion wa CMC mu slurry akuti ndi mapangidwe olimba maukonde dongosolo kudzera hydrogen zomangira ndi van der Waals mphamvu pakati macromolecules.Madzi akalowa mu chipika cha CMC, magulu a hydrophilic okhala ndi madzi ocheperako amatupa, pomwe ma hydrophilic ochulukirapo amasiyana atangotupa.Magulu a inhomogeneous hydrophilic mukupanga kwa CMC amabweretsa kusagwirizana kwa tinthu tating'ono ta micelles.Kutupa kwa hydration kumachitika mkati mwa micelles, ndikupanga wosanjikiza wamadzi kunja.Kumayambiriro kwa kusungunuka, ma micelles amakhala omasuka mu colloid.Mphamvu ya van der Waals pang'onopang'ono imabweretsa micelles palimodzi, ndipo madzi omangikawo amapanga mawonekedwe a network chifukwa cha asymmetry ya kukula ndi mawonekedwe.Kapangidwe ka netiweki ka fiber CMC kamakhala ndi voliyumu yayikulu, kumamatira mwamphamvu, komanso kumachepetsa kuwonongeka kwa glaze.
Levitation Mmene
Popanda zowonjezera, glaze slurry idzakhazikika chifukwa cha mphamvu yokoka pakapita nthawi, ndipo kuwonjezera dongo lambiri sikokwanira kuti izi zisachitike.Komabe, kuwonjezera kuchuluka kwa CMC kumatha kupanga maukonde omwe amathandizira mphamvu yokoka ya mamolekyu a glaze.The CMC mamolekyu kapena ayoni kutambasula mu glaze ndi kutenga danga, kuteteza kukhudzana mamolekyu glaze ndi particles, amene bwino dimensional bata slurry.Makamaka, ndi zoipa mlandu CMC anions kubweza zoipa mlandu particles dongo, zikubweretsa kuwonjezeka kuyimitsidwa kwa glaze slurry.Izi zikutanthauza kuti CMC ili ndi kuyimitsidwa bwino mu glaze slurry.Mawonekedwe a netiweki opangidwa ndi CMC amathandizanso kuchepetsa kuwonongeka kwa glaze ndikuwonetsetsa kutha kwapamwamba.Ponseponse, CMC imatenga gawo lofunikira pakukhazikika ndi kuyimitsidwa kwa glaze slurry, komwe ndikofunikira kuti tipeze zotsatira zosasinthika komanso zapamwamba kwambiri pakuwunikira.
Mafunso Oti Muwaganizire Posankha CMC
Kugwiritsa ntchito bwino kwa CMC popanga glaze kumatha kusintha kwambiri mtundu wa chinthu chomaliza.Kuti muwonetsetse zotsatira zabwino, pali mfundo zingapo zofunika kuzitsatira.Choyamba, ndikofunikira kuyang'ana mtundu wa CMC musanagule ndikusankha zoyenera kupanga.Powonjezera CMC ku glaze pa mphero, zitha kuthandiza kukonza bwino mphero.Chidwi chiyeneranso kuperekedwa ku chiŵerengero cha madzi-to-CMC pamene kuthira madzi kuti mukwaniritse zotsatira zake.
The glaze slurry iyenera kuloledwa kuvunda kwa tsiku limodzi kapena awiri kuti iwonetsetse kuti ili yokhazikika ndipo CMC ikhoza kusewera bwino.Ndikofunikiranso kusintha moyenera kuchuluka kwa CMC yowonjezeredwa molingana ndi kusintha kwa nyengo, ndikuwonjezera kwambiri m'chilimwe, kucheperako m'nyengo yozizira, ndi 0.05% mpaka 0.1% pakati.Mlingo ukasiyidwa mosasinthika m'nyengo yozizira, ukhoza kuyambitsa kutentha kwambiri, kuyanika pang'onopang'ono, ndi glaze yomata.Mosiyana ndi zimenezi, mlingo wosakwanira umapangitsa kuti pakhale mdima wandiweyani komanso wonyezimira.
M'chilimwe, kutentha kwambiri kumatha kusokoneza kukhuthala kwa CMC chifukwa cha chikoka cha bakiteriya.Chifukwa chake, ndikofunikira kuchita ntchito yodana ndi dzimbiri ndikuwonjezera zowonjezera zoyenera kuti mukhalebe ndi CMC.Pomaliza, mukamagwiritsa ntchito glaze, tikulimbikitsidwa kuti musefa ndi sieve pamwamba pa 100 mesh kuti zotsalira za CMC zisakhudze pamwamba pa glaze panthawi yowombera.Potsatira malangizowa, CMC itha kugwiritsidwa ntchito bwino popanga glaze kuti ikhale yabwino.
