CMC qib ceramic

Ceramic qib CMC Sodium carboxymethyl celluloseCov tshuaj no tuaj yeem yaj nrog lwm cov nplaum thiab cov resins uas yaj tau hauv dej. Qhov viscosity ntawm CMC kua txo qis nrog qhov kub nce, thiab qhov viscosity yuav rov qab los tom qab txias. CMC aqueous kua yog cov kua tsis-Newtonian nrog pseudoplasticity, thiab nws cov viscosity txo qis nrog qhov nce ntawm lub zog tangential, uas yog hais tias, qhov fluidity ntawm cov tshuaj zoo dua nrog qhov nce ntawm lub zog tangential. Sodium carboxymethyl cellulose (CMC) kua muaj cov qauv network tshwj xeeb, tuaj yeem txhawb nqa lwm yam khoom, yog li tag nrho lub cev tau sib npaug zos rau hauv ib qho tag nrho.

CMC qib ceramic siv tau rau hauv lub cev ceramic, glazing pulp, thiab fancy glaze. Siv rau hauv lub cev ceramic, nws yog ib qho tshuaj zoo rau kev txhawb zog, uas tuaj yeem txhawb zog cov av nkos thiab xuab zeb kom pwm tau zoo, pab txhawb kev ua kom lub cev zoo nkauj thiab ua kom lub cev ntsuab muaj zog dua.

Cov ntawv thov:

1Daim ntawv thov hauv cov xim luam ntawv ceramic

CMC muaj kev yaj zoo, kev daws teeb meem siab thiab yuav luag tsis muaj cov khoom tsis sib xws. Nws muaj kev sib xyaw ua ke zoo heev thiab lubricity, uas tuaj yeem txhim kho kev hloov pauv ntawm kev luam ntawv thiab cov nyhuv tom qab ua tiav ntawm cov xim luam ntawv. Lub caij no, CMC muaj cov nyhuv thickening, dispersion thiab stability zoo thaum siv rau cov xim luam ntawv ceramic:

* Kev luam ntawv zoo rheology kom ntseeg tau tias du printing;

* Cov qauv luam tawm yog qhov tseeb thiab xim zoo ib yam;

* Kev du ntawm cov kua, lubricity zoo, siv tau zoo;

* Zoo solubility dej, yuav luag txhua yam khoom yaj, tsis nplaum net, tsis thaiv net;

* Cov kev daws teeb meem muaj kev pom tseeb siab thiab kev nkag mus rau hauv lub vas zoo;

* Kev txo qhov shear zoo heev, ua kom zoo dua qhov kev hloov pauv ntawm kev luam ntawv glaze;

2Daim ntawv thov hauv cov xim av infiltration glaze

Cov kua nplaum embossing muaj ntau cov ntsev uas yaj tau, thiab cov kua qaub, cov kua nplaum embossing CMC muaj cov kua qaub zoo dua thiab cov ntsev tsis kam, yog li ntawd cov kua nplaum embossing hauv kev siv thiab kev tso kom ruaj khov, kom tiv thaiv kev hloov pauv ntawm viscosity thiab cuam tshuam rau qhov sib txawv xim, zoo heev txhim kho kev ruaj khov ntawm cov kua nplaum embossing:

* Solubility zoo, tsis muaj ntsaws, permeability zoo;

* Zoo sib phim nrog glaze, yog li ntawd lub paj glaze stability;

* Zoo acid tsis kam, alkali tsis kam, ntsev tsis kam thiab ruaj khov, tuaj yeem ua kom cov viscosity ntawm infiltration glaze ruaj khov;

* Kev ua tau zoo ntawm kev daws teeb meem yog qhov zoo, thiab kev ruaj khov viscosity yog qhov zoo, tuaj yeem tiv thaiv kev hloov pauv viscosity cuam tshuam rau qhov sib txawv xim.

3. Daim ntawv thov hauv lub cev ceramic

CMC muaj cov qauv polymer linear tshwj xeeb. Thaum CMC raug ntxiv rau hauv dej, nws cov hydrophilic pawg raug sib xyaw nrog dej los tsim ib txheej solvated, yog li ntawd CMC molecules maj mam dispersed hauv dej. CMC polymers vam khom hydrogen bond thiab van der Waals force los tsim ib lub network qauv, yog li qhia adhesion. CMC rau lub cev embryo ceramic tuaj yeem siv ua excipient, plasticizer thiab strengthening agent rau lub cev embryo hauv kev lag luam ceramic.

* Tsawg dua cov tshuaj, qhov ntsuab khoov zog ua kom muaj txiaj ntsig zoo dua yog qhov pom tseeb;

* Txhim kho qhov ceev ntawm kev ua tiav ntsuab, txo kev siv zog ntau lawm;

* Zoo poob hluav taws, tsis muaj residue tom qab hlawv, tsis cuam tshuam rau xim ntsuab;

* Yooj yim rau kev khiav lag luam, tiv thaiv kev dov glaze, tsis muaj glaze thiab lwm yam tsis zoo;

* Nrog cov nyhuv tiv thaiv kev coagulation, tuaj yeem txhim kho qhov fluidity ntawm glaze paste, yooj yim rau tshuaj tsuag glaze ua haujlwm;

* Ua ib qho khoom siv billet, ua rau kom cov khoom siv xuab zeb zoo dua, yooj yim rau kev tsim lub cev;

* Muaj zog tiv taus kev siv tshuab, tsawg dua kev puas tsuaj ntawm cov saw hlau hauv cov txheej txheem ntawm kev sib tsoo pob thiab kev sib xyaw tshuab;

* Ua tus neeg sawv cev txhawb zog ntawm cov hlau billet, ua kom lub zog khoov ntawm cov hlau billet ntsuab, txhim kho kev ruaj khov ntawm cov hlau billet, txo qhov kev puas tsuaj;

* Muaj zog ncua thiab dispersion, tuaj yeem tiv thaiv cov khoom siv raw tsis zoo thiab cov khoom me me hauv cov pulp, kom cov slurry sib npaug zos;

* Ua kom cov dej noo hauv lub billet qhuav sib npaug, tiv thaiv kom qhuav thiab tawg, tshwj xeeb tshaj yog siv rau hauv cov vuas pem teb loj thiab cov cib ci ci, qhov cuam tshuam yog qhov pom tseeb.

4. Daim ntawv thov hauv cov khoom siv ceramic glaze slurry

CMC yog ib hom polyelectrolyte, feem ntau yog siv ua ib qho binder thiab suspension hauv glaze slurry. Thaum CMC nyob rau hauv glaze slurry, dej nkag mus rau hauv CMC yas daim sab hauv, hydrophilic pawg ua ke nrog dej, tsim dej nqus expansion, thaum lub micelle hauv hydration expansion, sab hauv thiab sab nraud ua ke nrog dej txheej tsim, micelle nyob rau hauv thaum ntxov yaj hauv cov kua nplaum, vim qhov loj me, cov duab tsis sib xws, thiabcsib xyaw nrog cov dej maj mam tsim cov qauv network, ntim loj heev, Yog li ntawd, nws muaj peev xwm lo rau zoo:

* Nyob rau hauv qhov xwm txheej ntawm cov tshuaj tsawg, zoo kho qhov rheology ntawm glaze paste, yooj yim rau thov glaze;

* Txhim kho qhov kev ua tau zoo ntawm cov glaze dawb paug, txhim kho lub zog glaze, tiv thaiv kev deglazing;

* Kev ci ntsa iab zoo, cov nplaum glaze ruaj khov, thiab tuaj yeem txo qhov pinhole ntawm cov sintered glaze;

* Kev sib kis zoo heev thiab kev tiv thaiv colloid kev ua tau zoo, tuaj yeem ua rau cov glaze slurry nyob rau hauv lub xeev ruaj khov dispersion;

* Ua kom zoo dua qhov nro ntawm qhov glaze, tiv thaiv dej los ntawm glaze diffusion mus rau lub cev, ua rau kom du ntawm glaze;

* Tsis txhob tawg thiab luam ntawv tawg thaum lub sijhawm xa khoom vim yog qhov poob qis ntawm lub zog ntawm lub cev tom qab glazing.
