Carboxymethyl cellulose CMC-Ceramic qib

Lus piav qhia luv luv:

Carboxymethylation cov tshuaj tiv thaiv yog ib qho ntawm etherification technologies.Tom qab Carboxymethylation ntawm cellulose, carboxymethyl cellulose (CMC) tau txais.Nws cov tshuaj aqueous muaj cov haujlwm ntawm thickening, film-forming, bonding, dej tuav, colloidal tiv thaiv, emulsification thiab ncua kev kawm ntawv.Nws yog dav siv hauv roj av, zaub mov, tshuaj, textile thiab papermaking industries.Nws yog ib qho tseem ceeb tshaj plaws ntawm cov cellulose ethers.Nrog peb cov kws tshaj lij nyob rau lub sijhawm ntev hauv kev lag luam tshuaj lom neeg, peb puas muab koj cov lus qhia tshaj lij ntawm cov khoom thiab cov kev daws teeb meem rau koj lub hom phiaj tshwj xeeb.Peb zoo siab los pab koj xaiv cov ntaub ntawv uas tsim nyog rau koj.Cia li nias mus nrhiav cov ntawv thov hauv koj qhov kev lag luam: CMC hauv cov khoom noj, roj av, luam ntawv thiab dyeing, ceramics, tshuaj txhuam hniav, floating beneficiation, roj teeb, txheej, putty hmoov thiab papermaking.

Ceramic CMC qauv: C1074 C1274 C1083 C1583
Sodium carboxymethylcellulose CMC hauv kev lag luam ceramic li billet excipient, plasticizer, ntxiv dag zog rau tus neeg sawv cev.Siv nyob rau hauv ceramic pobzeb hauv qab glaze thiab nto glaze, tuaj yeem ua rau lub cev glaze nyob rau hauv lub xeev ruaj khov ntawm dispersion.Nws yog tsuas yog siv rau thickening, bonding thiab dispersing zog ntawm printing glaze.

CMC-Application In Ceramics

Kev ua haujlwm ntawm CMC hauv ceramic pobzeb hauv qab glaze thiab nto glaze:
- Khaws lub glaze nyob rau hauv ib tug ruaj khov dispersion xeev;
- Txhim kho qhov nro ntawm glaze;
-Slow cia qhov diffusion ntawm dej los ntawm glaze mus rau billet;
- Ua kom lub smoothness ntawm glaze;
-Tsis txhob tawg thiab luam ntawv tawg thaum lub sijhawm thauj mus los vim qhov txo qis ntawm lub cev ntsuab lub zog tom qab glazing;
- Txo glaze pinholes tom qab sintering.
Daim ntawv thov ntawm CMC hauv ceramic pobzeb hauv qab glaze thiab nto glaze:
CMC yog ib qho zoo heev stabilizer thiab binder.Thaum siv hauv qab glaze, nws tuaj yeem ua rau muaj kev sib raug zoo ntawm cov glaze slurry thiab lub cev ntsuab, ua rau lub cev glaze nyob rau hauv ib qho chaw ruaj khov dispersion xeev, txhim kho qhov nro ntawm lub glaze, tiv thaiv cov diffusion ntawm dej los ntawm glaze. lub cev ntsuab, thiab nce qhov smoothness ntawm glaze nto;CMC yog tus neeg sawv cev zoo tshaj plaws, stabilizer thiab binder.Thaum siv cov glaze, nws tuaj yeem txhim kho qhov nro ntawm glaze, ua rau lub cev glaze nyob rau hauv ib qho chaw ruaj khov dispersion xeev, tiv thaiv cov dej ntws los ntawm glaze rau lub cev, tsis txhob poob ntawm lub zog ntawm lub cev nrog tuab. glaze, ua rau tawg thiab luam ntawv tawg thaum lub sij hawm thauj mus los, thiab txo cov pinhole phenomenon ntawm glaze tom qab ci.
Kev ua haujlwm ntawm CMC hauv lub cev ceramic:
-Nws tuaj yeem ua kom lub zog sib txuas ntawm qhov khoob thiab qhov khoob yog yooj yim rau kev tsim;
- Txhim kho qhov khoov lub zog ntawm lub cev ntsuab thiab txo qhov kev puas tsuaj ntawm lub cev ntsuab;
- Ua kom cov dej hauv qhov khoob evaporate tusyees kom tsis txhob qhuav thiab tawg.
Kev siv CMC hauv lub cev ceramic:
CMC yog siv los ua excipient, plasticizer thiab reinforcing agent nyob rau hauv ceramic lub cev.Ntxiv qhov tsim nyog ntawm CMC rau hauv lub cev tuaj yeem ua rau muaj kev sib raug zoo ntawm lub cev, ua rau lub cev yooj yim tsim, txhim kho lub zog flexural los ntawm 2-3 zaug, txhim kho kev ruaj ntseg ntawm lub cev, txhim kho cov khoom lag luam zoo heev ntawm ceramics thiab txo tus nqi ua tom qab.Vim yog qhov sib ntxiv ntawm CMC, cov dej noo hauv cov khoom siv hauv lub cev ntsuab yog qhov sib xws thiab tsis tu ncua los tiv thaiv kom qhuav thiab tawg.Tshwj xeeb tshaj yog thaum thov rau cov vuas luaj loj hauv pem teb thiab polished cib lub cev, cov nyhuv yog pom tseeb dua.
Daim ntawv thov of CMC in luam ntawv glaze:
CMC yog ib qho zoo heev stabilizer nrog muaj zog ncua kev kawm ntawv thiab dispersion muaj peev xwm, tsawg insoluble teeb meem, siab transparency, thiab zoo heev acid thiab alkali kuj thiab ntsev kuj.Nws ua kom nrawm nrawm ntawm cov ntawv luam tawm glaze, zoo txo lub sijhawm ntawm kev tu lub tshuab luam ntawv, txo cov cim ntawm cov xim sib txawv, thiab ua kom muaj kev ruaj ntseg ntawm cov ntawv luam tawm glaze thiab infiltrated glaze thaum khaws cia.
