Kev siv ntawm Carboxymethyl Cellulose Sodium hauv Ceramic Glaze Slurry

Carboxymethyl cellulose sodium (CMC) pom ntau daim ntawv thov nyob rau hauv ceramic glaze slurries vim nws cov khoom rheological, dej tuav peev xwm, thiab muaj peev xwm tswj viscosity. Nov yog qee qhov kev siv ntawm CMC hauv ceramic glaze slurries:

1. viscosity tswj:
   • CMC yog siv los ua tus neeg sawv cev thickening hauv ceramic glaze slurries los tswj viscosity. Los ntawm kev kho qhov concentration ntawm CMC, manufacturers tuaj yeem ua tiav qhov xav tau viscosity rau kev thov kom raug thiab ua raws li cov khoom siv ceramic. CMC pab tiv thaiv kom tsis txhob muaj dej ntau dhau lossis khiav ntawm glaze thaum thov.
2. Suspension ntawm Particles:
   • CMC ua raws li tus neeg sawv cev ncua, pab kom cov khoom siv (piv txwv li, pigments, fillers) sib npaug sib faib thoob plaws hauv cov glaze slurry. Qhov no tiv thaiv kev nyob los yog sedimentation ntawm hais, kom ntseeg tau tias uniformity nyob rau hauv cov xim thiab kev ntxhib los mos ntawm glaze.
3. Kev tuav dej:
   • CMC muaj cov khoom tuav dej zoo heev, uas pab tswj cov dej noo ntawm ceramic glaze slurries thaum khaws cia thiab daim ntawv thov. Qhov no tiv thaiv cov glaze los ntawm ziab sai heev, tso cai rau lub sij hawm ua hauj lwm ntev thiab zoo adhesion rau ceramic nto.
4. Thixotropic Properties:
   • CMC imparts thixotropic cwj pwm rau ceramic glaze slurries, txhais tau hais tias lub viscosity txo nyob rau hauv shear stress (piv txwv li, thaum stirring los yog daim ntawv thov) thiab nce thaum muaj kev ntxhov siab raug tshem tawm. Cov cuab yeej no txhim kho qhov ntws thiab kis tau ntawm cov glaze thaum tiv thaiv sagging los yog poob tom qab daim ntawv thov.
5. Adhesion Enhancement:
   • CMC txhim kho cov adhesion ntawm ceramic glaze slurries rau lub substrate nto, xws li av nplaum lub cev los yog ceramic vuas. Nws tsim ib zaj duab xis nyias, tsis sib xws ntawm qhov chaw, txhawb kev sib txuas zoo dua thiab txo qhov kev pheej hmoo ntawm qhov tsis xws luag xws li pinholes lossis hlwv hauv cov glaze raug rho tawm haujlwm.
6. Rheology Hloov Kho:
   • CMC hloov kho cov khoom rheological ntawm ceramic glaze slurries, cuam tshuam rau lawv tus cwj pwm ntws, shear thinning, thiab thixotropy. Qhov no tso cai rau cov tuam txhab tsim kho cov yam ntxwv rheological ntawm glaze rau cov kev thov tshwj xeeb thiab cov kev xav tau.
7. Txo qhov tsis xws luag:
   • Los ntawm kev txhim kho cov dej ntws, adhesion, thiab uniformity ntawm ceramic glaze slurries, CMC pab txo qhov tsis xws luag ntawm cov glaze raug rho tawm haujlwm, xws li tawg, crazing, los yog tsis sib xws. Nws txhawb nqa qhov smoother thiab zoo ib yam glaze nto, txhim kho qhov zoo nkauj thiab zoo ntawm cov khoom siv ceramic.

carboxymethyl cellulose sodium (CMC) plays lub luag haujlwm tseem ceeb hauv ceramic glaze slurries los ntawm kev muab viscosity tswj, particle suspension, dej tuav, thixotropic zog, adhesion li, rheology hloov kho, thiab txo qhov tsis xws luag. Nws siv los txhim kho kev ua, daim ntawv thov, thiab zoo ntawm ceramic glazes, pab rau zus tau tej cov high-zoo ceramic cov khoom uas ntshaw aesthetic thiab kev ua tau zoo yam ntxwv.
