Ceramic grade CMC

Ceramic grade CMC Sodium carboxymethyl celluloseyankho akhoza kusungunuka ndi zomatira madzi sungunuka ndi utomoni. Kukhuthala kwa njira ya CMC kumachepa ndi kuwonjezeka kwa kutentha, ndipo mamasukidwe amatsitsimutso amachira pambuyo pozizira. CMC amadzimadzi yothetsera ndi sanali Newtonian madzimadzi ndi pseudoplasticity, ndi mamasukidwe akayendedwe ake amachepetsa ndi kuwonjezeka kwa tangential mphamvu, ndiko kunena, fluidity ya yankho amakhala bwino ndi kuwonjezeka kwa tangential mphamvu. Sodium carboxymethyl cellulose (CMC) yankho ali ndi dongosolo lapadera maukonde, akhoza bwino kuthandizira zinthu zina, kotero kuti dongosolo lonse wogawana omwazika mu lonse.

Ceramic grade CMC itha kugwiritsidwa ntchito mu thupi la ceramic, glazing zamkati, ndi glaze wokongola. Amagwiritsidwa ntchito mu thupi la ceramic, ndi chinthu chabwino cholimbikitsa, chomwe chingalimbikitse kuumbika kwa matope ndi mchenga, kuthandizira kupanga thupi ndikuwonjezera mphamvu yopinda ya thupi lobiriwira.

Mapulogalamu:

1. Ntchito mu ceramic yosindikiza glaze

CMC ili ndi kusungunuka kwabwino, kuwonekera kwakukulu kwa yankho komanso pafupifupi palibe zinthu zosagwirizana. Ili ndi kumeta ubweya wabwino kwambiri wa shear ndi lubricity, zomwe zimatha kusintha kwambiri kusinthasintha kwa kusindikiza komanso kukonzanso pambuyo pakusindikiza kwa glaze yosindikiza. Pakadali pano, CMC ili ndi kukhuthala bwino, kubalalitsidwa komanso kukhazikika ikagwiritsidwa ntchito pa glaze yosindikiza ya ceramic:

* Rheology yabwino yosindikiza kuti mutsimikizire kusindikiza kosalala;

* Njira yosindikizidwa ndi yomveka bwino ndipo mtundu wake ndi wofanana;

* Kusalala kwambiri kwa yankho, mafuta abwino, kugwiritsa ntchito bwino;

* Kusungunuka kwamadzi bwino, pafupifupi zinthu zonse zosungunuka, osati ukonde womata, osatsekereza ukonde;

* Yankho lake limakhala lowonekera kwambiri komanso kulowa bwino kwa ukonde;

* Kumeta ubweya wabwino kwambiri, kumathandizira kwambiri kusinthika kwa kusindikiza kwa glaze;

2. Ntchito mu ceramic infiltration glaze

Embossing glaze muli ambiri sungunuka mchere zinthu, ndi acidic, embossing glaze CMC ali wapamwamba asidi kukana ndi mchere kukana bata, kuti embossing glaze ntchito ndi masungidwe ndondomeko kukhala khola mamasukidwe akayendedwe, kupewa kusintha mamasukidwe akayendedwe ndi zimakhudza kusiyana kwa mtundu, kumathandizira kwambiri kukhazikika kwa embossing glaze:

* Kusungunuka kwabwino, palibe pulagi, kukwanira bwino;

* Good yofananira ndi glaze, kuti duwa glaze bata;

* Good asidi kukana, alkali kukana, mchere kukana ndi bata, kuonetsetsa mamasukidwe akayendedwe a infiltration glaze khola;

* Kuwongolera magwiridwe antchito ndikwabwino, komanso kukhazikika kwa mamachulukidwe abwino, kumatha kuletsa kusintha kwamawonekedwe kukhudza kusiyana kwa mtundu.

3. Kugwiritsa ntchito mu thupi la ceramic

CMC ili ndi mawonekedwe apadera a polima. CMC ikawonjezeredwa kumadzi, gulu lake la hydrophilic limaphatikizidwa ndi madzi kuti likhale losanjikiza, kotero kuti mamolekyu a CMC amamwazikana m'madzi. Ma polima a CMC amadalira chomangira cha haidrojeni ndipo van der Waals amakakamiza kupanga maukonde, motero akuwonetsa kumamatira. CMC ya ceramic mluza thupi angagwiritsidwe ntchito ngati excipient, plasticizer ndi kulimbikitsa wothandizila mwana wosabadwayo mu makampani ceramic.

* Mlingo wocheperako, mphamvu yopindika yobiriwira imakulitsa magwiridwe antchito ndizodziwikiratu;

* Kupititsa patsogolo liwiro lobiriwira, kuchepetsa kugwiritsa ntchito mphamvu zamagetsi;

* Good imfa ya moto, palibe zotsalira pambuyo kuwotcha, sikukhudza wobiriwira mtundu;

* Yosavuta kugwiritsa ntchito, kupewa kugudubuzika kwa glaze, kusowa kwa glaze ndi zolakwika zina;

* Ndi odana ndi coagulation tingati kusintha fluidity wa glaze phala, zosavuta utsi glaze ntchito;

* Monga billet excipient, kuwonjezera plasticity wa zinthu mchenga, zosavuta kupanga thupi;

* Amphamvu mawotchi kuvala kukana, zochepa maselo unyolo kuwonongeka mu ndondomeko ya mpira mphero ndi makina oyambitsa;

* Monga wothandizira billet, onjezani mphamvu yopindika ya billet wobiriwira, sinthani kukhazikika kwa billet, chepetsani kuwonongeka;

* Wamphamvu kuyimitsidwa ndi kubalalitsidwa, zingalepheretse osauka zopangira ndi zamkati particles kukhazikika, kuti slurry wogawana omwazika;

* Pangani chinyezi mu billet kuti chisasunthike mofanana, kupewa kuyanika ndi kusweka, makamaka kumagwiritsidwa ntchito muzitsulo zazikulu zamatabwa zapansi ndi mapepala a njerwa opukutidwa, zotsatira zake ndi zoonekeratu.

4. Kugwiritsa ntchito mu ceramic glaze slurry

CMC ndi ya gulu la polyelectrolyte, lomwe limagwiritsidwa ntchito makamaka ngati chomangira ndi kuyimitsidwa mu glaze slurry. Pamene CMC mu glaze slurry, madzi amalowa mu CMC pulasitiki chidutswa mkati, hydrophilic gulu pamodzi ndi madzi, kupanga madzi mayamwidwe kutambasuka, pamene micelle mu hydration kukula, mkati kunja pamodzi ndi wosanjikiza madzi aumbike, micelle mu gawo oyambirira kusungunuka mu njira zomatira, chifukwa cha kukula, mawonekedwe asymmetry, ndicophatikizidwa ndi madzi pang'onopang'ono anapanga dongosolo maukonde, voliyumu ndi lalikulu kwambiri, Choncho, ali amphamvu adhesion luso:

* Pansi pa mlingo otsika mlingo bwino kusintha rheology wa glaze phala, yosavuta kugwiritsa ntchito glaze;

* Sinthani magwiridwe antchito a glaze opanda kanthu, sinthani kwambiri mphamvu ya glaze, kupewa kugwa;

* Kuwala kowala kwambiri, phala lokhazikika la glaze, ndipo chitha kuchepetsa tsinde pa glaze wonyezimira;

* Kubalalika kwabwino komanso chitetezo cha colloid, kungapangitse kuti glaze ikhale yokhazikika yobalalika;

* Mogwira bwino pamwamba mavuto a glaze, kuteteza madzi glaze kufalikira kwa thupi, kuonjezera kusalala kwa glaze;

* Pewani kusweka ndi kusindikiza fracture panthawi yotumiza chifukwa cha kugwa kwa mphamvu ya thupi pambuyo pa glazing.
