Ceramic ọkwa CMC

Ceramic ọkwa CMC sodium carboxymethyl celluloseEnwere ike igbari ihe ngwọta na nrapado na resins ndị ọzọ na-agbaze mmiri. Viscosity nke CMC ngwọta na-ebelata na mmụba nke okpomọkụ, na viscosity ga-agbake mgbe jụrụ oyi. CMC aqueous solution bụ mmiri na-abụghị Newtonian na pseudoplasticity, na viscosity ya na-ebelata na mmụba nke ike tangential, ya bụ, mmiri mmiri nke ngwọta na-adị mma na mmụba nke ike tangential. Sodium carboxymethyl cellulose (CMC) ngwọta nwere pụrụ iche netwọk Ọdịdị, nwere ike nke ọma na-akwado ndị ọzọ bekee, nke mere na dum usoro evenly chụsasịrị n'ime a dum.

1. Ngwa na seramiiki obibi glaze

CMC nwere ezigbo solubility, nghọta ngwọta dị elu na ọ fọrọ nke nta ka ọ bụrụ ihe na-adabaghị adaba. Ọ nwere mma shear dilution na mmanu mmanu, nke nwere ike imeziwanye ikike obibi akwụkwọ na mmetụta post-processing nke glaze obibi. Ka ọ dị ugbu a, CMC nwere mmetụta dị mma, mgbasa na nkwụsi ike mgbe etinyere ya na glaze ebipụta seramiiki:

* rheology obibi akwụkwọ dị mma iji hụ na mbipụta dị larịị;

* Ụkpụrụ e biri ebi doro anya na agba na-agbanwe agbanwe;

* Ịdị nro dị elu nke ngwọta, ezigbo mmanu mmanu, mmetụta eji eme ihe dị mma;

* Ezigbo solubility mmiri, ihe fọrọ nke nta ka ọ bụrụ ihe niile agbazere, ọ bụghị ụgbụ nnyapade, anaghị egbochi ụgbụ;

* Ngwọta ahụ nwere nghọta dị elu na ntinye ntanetị dị mma;

* Ọkachamara shiee dilution, na-emeziwanye ikike obibi akwụkwọ nke glaze;

2. Ngwa na seramiiki infiltration glaze

Embossing glaze nwere ọnụ ọgụgụ dị ukwuu nke soluble nnu bekee, na acidic, embossing glaze CMC nwere elu acid nguzogide na nnu na-eguzogide nkwụsi ike, nke mere na embossing glaze na ojiji na ntinye usoro iji nọgide na-enwe ike viscosity, iji gbochie mgbanwe nke viscosity na-emetụta. agba dị iche, na-eme ka nkwụsi ike nke embossing glaze dịkwuo mma:

* Ezigbo solubility, enweghị plọg, ezigbo permeability;

* Ezigbo mma na glaze, nke mere na ifuru glaze kwụsie ike;

* Ezigbo nguzogide acid, nguzogide alkali, nguzogide nnu na nkwụsi ike, nwere ike ime ka viscosity nke infiltration glaze kwụsie ike;

* Ngwọta ọkwa arụmọrụ dị mma, na nkwụsi ike viscosity dị mma, nwere ike igbochi mgbanwe viscosity na-emetụta ọdịiche agba.

3. Ngwa na ahụ seramiiki

CMC nwere usoro polymer linear pụrụ iche. Mgbe a na-agbakwunye CMC na mmiri, a na-ejikọta ìgwè hydrophilic ya na mmiri na-eme ka oyi akwa dị nro, nke mere na mkpụrụ ndụ CMC na-eji nwayọọ nwayọọ gbasaa na mmiri. Ndị polymer CMC na-adabere na njikọ hydrogen na van der Waals na-amanye ịmepụta usoro netwọk, si otú a na-egosi nrapado. Enwere ike iji CMC maka ahụ ẹmbrayo seramiiki mee ihe dị ka ihe mgbakwunye, plasticizer na onye na-ewusi ahụ embrayo na ụlọ ọrụ seramiiki.

* Obere usoro onunu ogwu, ike na-ehulata akwụkwọ ndụ akwụkwọ ndụ na-abawanye arụmọrụ pụtara ìhè;

* Meziwanye ọsọ nhazi akwụkwọ ndụ akwụkwọ ndụ, belata oriri ike mmepụta;

* Ọkụ ọkụ dị mma, ọ nweghị ihe fọdụrụ mgbe ọkụ, anaghị emetụta agba ndụ ndụ;

* Ọ dị mfe ịrụ ọrụ, gbochie ịgbagharị glaze, enweghị glaze na ntụpọ ndị ọzọ;

* Site na mmetụta mgbochi coagulation, nwere ike melite fluidity nke glaze mado, dị mfe ịgba glaze ọrụ;

* Dị ka billet excipient, mụbaa plasticity nke ájá ihe onwunwe, dị mfe na-etolite ahụ;

* ike n'ibu na-eyi na-eguzogide, obere molekụla yinye mmebi na usoro nke igwe-egwe ọka na n'ibu ịkpali;

* Dị ka onye na-ewusi billet ike, na-abawanye ike na-ehulata nke billet akwụkwọ ndụ akwụkwọ ndụ, meziwanye nkwụsi ike nke billet, belata ọnụego mmebi;

* Strong nkwusioru na dispersion, nwere ike igbochi ogbenye akụrụngwa na pulp ahụ edozi, nke mere na slurry evenly gbasasịrị;

* Mee ka mmiri dị n'ime billet kpochaa nke ọma, gbochie ihicha na ịgbawa, ọkachasị ejiri ya na akwa akwa akwa akwa na akwa brik na-egbu maramara, nsonaazụ ahụ pụtara ìhè.

4. Ngwa na seramiiki glaze slurry

CMC bụ nke klaasị polyelectrolyte, nke a na-ejikarị dị ka ihe nkedo na nkwusioru na slurry glaze. Mgbe CMC na glaze slurry, mmiri seep n'ime CMC plastic ibe n'ime, hydrophilic otu jikọtara na mmiri, na-emepụta mmiri absorption mgbasa, mgbe micelle na hydration mgbasa, esịtidem mpụta jikọtara na mmiri oyi akwa na-guzobere, micelle na mmalite etisasịwo na-adọ na ngwọta nrapado, n'ihi nha, ọdịdị asymmetry, nacombied na mmiri nke nta nke nta kpụrụ netwọk Ọdịdị, olu bụ nnọọ nnukwu, Ya mere, o nwere ike adhesion ikike:

* N'okpuru ọnọdụ nke obere onunu ogwu, n'ụzọ dị irè dozie rheology nke glaze mado, dị mfe itinye glaze;

* Meziwanye arụmọrụ njikọ nke glaze oghere, kwalite ike glaze nke ukwuu, gbochie deglazing;

* Ọmarịcha glaze dị elu, tapawa glaze kwụsiri ike, ma nwee ike belata pinhole na glaze siri ike;

* Mgbasa dị mma na arụmọrụ colloid na-echebe, nwere ike ime ka glaze slurry na steeti mgbasasị kwụsiri ike;

* Na-emeziwanye esemokwu elu nke glaze nke ọma, gbochie mmiri ịgbasa glaze na ahụ, na-abawanye ire ụtọ nke glaze;

* Zenarị mgbaji na-ebi akwụkwọ mgbe a na-ebuga ya n'ihi mbelata ike nke ahụ mgbe glazing gasịrị.
