    1. Ngwa na seramiiki ebi akwụkwọ glaze

    CMC nwere ezigbo ike ịgbaze, nghọta dị elu nke ngwọta, ọ fọrọ nke nta ka ọ ghara ịdị n'otu. O nwere ezigbo mkpụcha na mmanụ dị mma, nke nwere ike ime ka mgbanwe mbipụta na mmetụta nhazi nke glaze mbipụta dị mma. Ka ọ dị ugbu a, CMC nwere ezigbo mmetụta nke ịcha, mgbasa na nkwụsi ike mgbe etinyere ya na glaze mbipụta seramiiki:
    * Ezi rheology ibipụta akwụkwọ iji hụ na ebi akwụkwọ dị ire ụtọ;
    * Ụkpụrụ e biri ebi doro anya, agba ya dịkwa otu;
    * Ọdịmma dị elu nke ngwọta, ezigbo mmanụ aṅụ, mmetụta ojiji dị mma;
    * Mmiri na-agbaze nke ọma, ihe fọrọ nke nta ka ọ bụrụ ihe niile agbazere agbaze, ọ bụghị ụgbụ na-arapara arapara, ọ bụghị ụgbụ na-egbochi;
    * Ngwọta ahụ nwere nghọta dị elu na ntinye aka dị mma;
    * Ezigbo mma ịkwa akwa, na-eme ka mgbanwe mbipụta nke glaze mbipụta dịkwuo mma nke ukwuu;

    2. Ngwa na seramiiki infiltration glaze

    Igwe e ji agbaze agbaze nwere ọtụtụ ihe nnu na-agbaze agbaze, CMC nke nwere acidic na-agbaze agbaze nwere ike iguzogide acid na iguzogide nnu, nke mere na ihe e ji agbaze ...ze agbazeze agbazeze agbazeze agbazeze agbazeze agbazeze agbazeze nke ukwuu.
    * Ọ na-agbaze nke ọma, enweghị plọg, ọ na-agbaze nke ọma;
    * Ndakọrịta dị mma na glaze, nke mere na glaze ifuru ahụ kwụsiri ike;
    * Ezigbo iguzogide acid, iguzogide alkali, iguzogide nnu na nkwụsi ike, nwere ike idobe viscosity nke glaze infiltration kwụsiri ike;
    * Arụmọrụ nhazi ngwọta dị mma, nkwụsi ike viscosity dịkwa mma, nwere ike igbochi mgbanwe viscosity imetụta ọdịiche agba.

    3. Ngwa n'ime ahụ seramiiki

    CMC nwere nhazi polima pụrụ iche. Mgbe etinyere CMC na mmiri, a na-ejikọta otu hydrophilic ya na mmiri iji mepụta oyi akwa gbazere agbaze, ka molekul CMC wee gbasaa nwayọ nwayọ n'ime mmiri. Polima CMC na-adabere na njikọ hydrogen na ike van der Waals iji mepụta nhazi netwọk, si otú a na-egosi nrapado. Enwere ike iji CMC maka ahụ embrayo seramiiki dị ka ihe mgbakwunye, ihe na-eme ka plastik sie ike na ihe na-eme ka ahụ embrayo sie ike na ụlọ ọrụ seramiiki.
    * Obere dose, ike ịgbagọ akwụkwọ ndụ akwụkwọ ndụ na-abawanye arụmọrụ doro anya;
    * Meziwanye ọsọ nhazi akwụkwọ ndụ akwụkwọ ndụ, belata oriri ike mmepụta;
    * Ọkụ dị mma, enweghị ihe fọdụrụ mgbe ọkụ gasịrị, anaghị emetụta agba akwụkwọ ndụ akwụkwọ ndụ;
    * Ọ dị mfe iji, gbochie mkpụgharị glaze, enweghị glaze na ntụpọ ndị ọzọ;
    * Site na mmetụta mgbochi coagulation, ọ nwere ike ime ka mmiri nke glaze mado dịkwuo mma, ọ dịkwa mfe ịgbasa ọrụ glaze;
    * Dịka ihe mgbakwunye billet, mee ka ihe ájá dịkwuo mma, ọ dị mfe ịmepụta ahụ;
    * Ike siri ike n'igbochi ihe eji arụ ọrụ, obere mmebi nke agbụ ígwè molekul n'usoro nke igwe bọọlụ na mkpali igwe;
    * Dịka ihe na-eme ka billet sie ike, mee ka ike ịgbagọ nke billet akwụkwọ ndụ dịkwuo elu, melite nkwụsi ike nke billet, belata ọnụego mmebi;
    * Nkwusioru siri ike na mgbasa, nwere ike igbochi ihe ndị na-adịghị mma na ihe ndị na-amị amị na-edozi, nke mere na slurry ahụ gbasaa nke ọma;
    * Mee ka mmiri dị na billet ahụ ghara ịpụ apụ nke ọma, gbochie ịkpọ nkụ na ịgbawa, karịsịa eji ya na billet taịlị ala buru ibu na billet brik a kpụchara akpụcha, mmetụta ya doro anya.

    4. Ngwa na seramiiki glaze slurry

    CMC so na klas polyelectrolyte, nke a na-ejikarị eme ihe dị ka ihe na-ejikọ ihe na ihe nkwusioru na ihe nkwusioru na ihe nkwusioru na ihe nkwusioru na ihe nkwusioru glaze. Mgbe CMC dị na ihe nkwusioru glaze, mmiri na-abanye n'ime ihe plastik CMC dị n'ime, otu hydrophilic jikọtara ya na mmiri, na-emepụta mgbasawanye nnabata mmiri, ebe a na-emepụta micelle na mgbasawanye hydration, mpụga dị n'ime jikọtara ya na oyi akwa mmiri, micelle na mmalite agbazere na ngwọta nrapado, n'ihi nha, ọdịdị asymmetry, ma jikọta ya na nhazi netwọk mmiri ji nwayọọ nwayọọ mepụta, olu ya buru ibu nke ukwuu. Ya mere, o nwere ike ịrapara siri ike:
    * N'ọnọdụ obere dose, gbanwee usoro ọgwụgwọ nke glaze mado nke ọma, dị mfe itinye glaze;
    * Meziwanye arụmọrụ njikọ nke glaze oghere ahụ, melite ike glaze nke ọma, gbochie iwepụ glaze;
    * Ọcha dị elu nke na-egbuke egbuke, ihe na-eme ka ọ dị nro, ma nwee ike ibelata oghere dị na ihe na-egbuke egbuke;
    * Mgbasa ozi dị mma na arụmọrụ nchekwa colloid, nwere ike ime ka slurry glaze dị na steeti mgbasa kwụsiri ike;
    * Na-eme ka nrụgide elu nke glaze dịkwuo mma nke ọma, gbochie mmiri ịgbasa glaze n'ahụ, mee ka glaze dịkwuo mma;
    * Zere mgbawa na ibipụta mgbawa n'oge ebuga n'ihi mbelata ike nke ahụ mgbe glazing gasịrị.
