Adhesion nyhuv
Lub adhesion ntawm CMC nyob rau hauv lub slurry yog ntaus nqi los ntawm tsim ib tug ruaj network qauv los ntawm hydrogen bonds thiab van der Waals rog ntawm macromolecules.Thaum cov dej nkag mus rau hauv CMC block, cov pab pawg hydrophilic nrog cov dej tsis txaus nyiam swell, thaum cov hydrophilic ntau cais tam sim ntawd tom qab o.Lub inhomogeneous hydrophilic pawg hauv CMC ntau lawm ua rau inconsistent dispersed particle loj ntawm micelles.Kev ywg dej o tshwm sim hauv cov micelles, tsim ib txheej dej khi rau sab nraud.Nyob rau hauv thaum ntxov theem ntawm dissolution, cov micelles yog dawb nyob rau hauv lub colloid.Lub van der Waals quab yuam maj mam coj cov micelles ua ke, thiab cov txheej txheem dej ua ke tsim ib lub network qauv vim qhov asymmetry ntawm qhov loj thiab cov duab.Lub fibrous CMC network qauv muaj lub ntim loj, muaj zog adhesion, thiab txo glaze tsis xws luag.

Yog tsis muaj additives, glaze slurry yuav khom vim lub ntiajteb txawj nqus dhau lub sij hawm, thiab ntxiv ib co av nplaum tsis txaus los tiv thaiv qhov no tshwm sim.Txawm li cas los xij, qhov sib ntxiv ntawm qee qhov ntawm CMC tuaj yeem tsim cov qauv network uas txhawb nqa lub ntiajteb txawj nqus ntawm glaze molecules.Lub CMC molecules los yog ions stretch nyob rau hauv lub glaze thiab nyob qhov chaw, tiv thaiv kev sib cuag ntawm glaze molecules thiab hais, uas pab txhim kho qhov seem stability ntawm slurry.Tshwj xeeb, qhov tsis zoo CMC anions tshem tawm cov av nplaum uas tsis zoo, ua rau muaj kev ncua ntxiv ntawm glaze slurry.Qhov no txhais tau hais tias CMC muaj kev ncua zoo hauv glaze slurry.Lub network qauv tsim los ntawm CMC kuj pab txo qis glaze tsis xws luag thiab xyuas kom meej ib tug du nto.Zuag qhia tag nrho, CMC plays lub luag haujlwm tseem ceeb hauv kev ruaj ntseg thiab kev ncua ntawm glaze slurry, uas yog ib qho tseem ceeb rau kev ua tiav cov txiaj ntsig zoo thiab cov txiaj ntsig zoo hauv cov txheej txheem glazing.
Cov lus nug los xav txog thaum xaiv CMC
Kev siv CMC kom zoo hauv kev tsim cov glaze tuaj yeem txhim kho qhov zoo ntawm cov khoom kawg.Txhawm rau kom muaj txiaj ntsig zoo tshaj plaws, muaj ob peb lub ntsiab lus tseem ceeb ua raws.Ua ntej, nws yog ib qho tseem ceeb los xyuas CMC qauv specification ua ntej kev yuav khoom thiab xaiv ib tug haum specification rau ntau lawm.Thaum ntxiv CMC rau glaze thaum lub sij hawm milling, nws tuaj yeem pab txhim kho milling efficiency.Kev saib xyuas kuj yuav tsum tau them rau qhov sib piv ntawm dej-rau-CMC thaum nchuav dej kom ua tiav cov txiaj ntsig siab tshaj plaws.
Lub glaze slurry yuav tsum tau tso cai rau rot rau ib hnub lossis ob zaug kom ntseeg tau tias nws ruaj khov txaus thiab CMC tuaj yeem ua tau zoo tshaj plaws.Nws tseem yog ib qho tseem ceeb uas yuav tsum tau kho tus nqi ntawm CMC ntxiv raws li kev hloov pauv raws caij nyoog, nrog rau feem ntau ntxiv rau lub caij ntuj sov, qhov tsawg tshaj plaws nyob rau lub caij ntuj no, thiab qhov ntau ntawm 0.05% mus rau 0.1% nyob nruab nrab.Yog tias qhov ntau npaum li cas tsis hloov pauv thaum lub caij ntuj no, nws tuaj yeem ua rau lub ntsej muag ci, qeeb ziab, thiab nplaum nplaum.Conversely, tsis txaus noj yuav ua rau ib tug ntom thiab ntxhib glaze nto.
Nyob rau lub caij ntuj sov, qhov kub thiab txias tuaj yeem degrade lub viscosity ntawm CMC vim cov kab mob cuam tshuam.Yog li ntawd, nws yog ib qho tsim nyog los ua haujlwm los tiv thaiv corrosion thiab ntxiv cov khoom tsim nyog kom tswj tau CMC zoo.Thaum kawg, thaum siv cov glaze, nws raug nquahu kom sieve nrog lub sieve saum toj no 100 mesh los tiv thaiv cov seem ntawm CMC los ntawm kev cuam tshuam cov glaze nto thaum tua.Los ntawm kev ua raws li cov lus qhia no, CMC tuaj yeem siv tau zoo hauv kev tsim glaze los txhim kho cov khoom zoo.
