Zvikumbiro zveCMC muCeramic Glaze
Ceramic glaze igirazi rejasi rinoiswa kune ceramics kuti iwedzere kunakidza, kusimba, uye kushanda. Iyo chemistry yeceramic glaze yakaoma, uye inoda kunyatso kudzora kweakasiyana ma paramita kuti uwane inodiwa zvivakwa. Imwe yeakakosha paramita ndeye CMC, kana yakakosha micelle concentration, inoita basa rakakosha mukuumbwa uye kugadzikana kwe glaze.
CMC ndiko kuunganidzwa kweva surfactants panotanga kuumbwa micelles. A micelle chimiro chinoumba apo mamorekuru epamusoro anoungana pamwechete mumhinduro, achigadzira chimiro chedenderedzwa chine hydrophobic miswe pakati uye misoro ye hydrophilic pamusoro. Muceramic glaze, ma surfactants anoita seanoparadzira anodzivirira kugadzika kwezvikamu uye anokurudzira kuumbwa kwekumiswa kwakagadzikana. Iyo CMC ye surfactant inotarisisa huwandu hwe surfactant inodiwa kuchengetedza yakagadzikana kuturika, izvo zvinozokanganisa kunaka kwe glaze.
Imwe yeanowanzo shandiswa yeCMC muceramic glaze yakaita seanoparadzira zvidimbu zveceramic. Ceramic particles ine maitiro ekugadzirisa nekukurumidza, izvo zvinogona kutungamirira kune kusaenzana kugovera uye kutadza kwepamusoro. Madispersants anobatsira kudzivirira kugadzika nekugadzira simba rinosemesa pakati pezvimedu, izvo zvinoita kuti zvirambe zvakamira mu glaze. Iyo CMC yeanoparadzira inosarudza hushoma hwekusungwa hunodiwa kuti uwane kupararira kunoshanda. Kana iyo yekusarudzika kweiyo dispersant yakanyanya kuderera, zvimedu zvichagara, uye glaze ichave isina kuenzana. Kune rimwe divi, kana iyo yekumisikidza yakawandisa, inogona kuita kuti glaze isagadzikane uye iparadzane kuita zvidimbu.
Imwe yakakosha application yeCMC mune ceramic glazeyakaita se rheology modifier. Rheology inoreva kudzidza kwekuyerera kwechinhu, uye muceramic glaze, inoreva nzira iyo glaze inoyerera uye inogara pamusoro peceramic surface. Iyo rheology ye glaze inokanganiswa nezvinhu zvakasiyana, zvinosanganisira particle size distribution, the viscosity yesvikiro inomisa, uye kusungirirwa uye rudzi rwekuparadzira. CMC inogona kushandiswa kugadzirisa rheology ye glaze nekushandura viscosity uye kuyerera zvivakwa. Semuyenzaniso, yakakwira CMC dispersant inogona kugadzira yakawedzera fluid glaze inoyerera zvakanaka uye zvakaenzana pamusoro pepamusoro, nepo yakaderera CMC dispersant inogona kugadzira gobvu glaze isingayerere nyore nyore.
CMC inogona zvakare kushandiswa kudzora kuomesa uye kupfura zvivakwa zveceramic glaze. Kana iyo glaze inoshandiswa kune ceramic surface, inofanira kuoma isati yatanga kupiswa. Iyo yekuomesa inogona kukanganiswa nezvinhu zvakasiyana, zvinosanganisira tembiricha uye hunyoro hwenzvimbo, ukobvu hweiyo glaze layer, uye kuvapo kwevanoshandisa surfactants. CMC inogona kushandiswa kugadzirisa iyo yekuomesa zvimiro zve glaze nekushandura kushushikana kwepamusoro uye viscosity yepakati inomisa. Izvi zvinogona kubatsira kudzivirira kutsemuka, kuputika, uye zvimwe zvirema zvinogona kuitika panguva yekuomesa.
Pamusoro pebasa rayo seanoparadzira uye rheology modifier, CMC inogona zvakare kushandiswa sebinder mune ceramic glaze. Binders zvinhu zvinobata glaze particles pamwechete uye zvinokurudzira kunamatira kune ceramic pamusoro. CMC inogona kuita sebhainda nekugadzira firimu rakatetepa pamusoro pezvikamu zveceramic, izvo zvinobatsira kuzvibata pamwe chete uye kukurudzira kunamatira. Huwandu hweCMC hunodiwa sebhainda hunoenderana nezvinhu zvakasiyana, zvinosanganisira saizi yechidimbu uye chimiro, kuumbwa kwe glaze, uye tembiricha yekupfura.
Mukupedzisa, iyo yakakosha micelle concentration (CMC) inoita basa rakakosha mukugadzirwa kweceramic glaze.
