Qhov Tseem Ceeb - Ceramic vs Porcelain
Ntau tus neeg xav tias Ceramic thiab Porcelain yog tib yam khoom thiab ob lo lus tuaj yeem siv sib hloov; Txawm li cas los xij, muaj qhov sib txawv ntawm cov ntaub ntawv no raws li lawv cov khoom thiab kev siv. Qhov sib txawv tseem ceeb ntawm ceramic thiab porcelain tuaj yeem piav qhia raws li hauv qab no. Porcelain yog hom khoom siv ceramic, tab sis nws cov txheej txheem txheej txheem suav nrog cua sov ntawm ceramics mus rau qhov kub thiab txias kom tau txais cov khoom xav tau. Cov khoom siv plooj (porcelain) kuj kim dua li cov khoom siv ceramic.
Porcelain yog dab tsi?
Porcelain yog cov khoom siv ceramic; Txawm li cas los xij, cov plooj (porcelain) yog tsim los ntawm cov khoom siv hluav taws xob cua sov ntawm qhov kub siab heev (12000C txog 14000C). Yog li ntawd, cov plooj (porcelain) muaj vitreous lossis glassy cov khoom xws li translucence (tso cai rau lub teeb kom dhau mus, tab sis diffusing nws kom cov khoom ntawm sab nraud tsis pom meej) thiab porosity tsawg.
Cov khoom siv plooj (porcelain) sib txawv raws li kev siv. Kaolin yog cov khoom siv tseem ceeb hauv cov plooj (porcelain); Tsis tas li ntawd, av nplaum minerals muaj nyob rau hauv me me kom txhim kho cov plasticity. Lwm cov ntaub ntawv raw yog feldspar, pob av nplaum, iav, pob txha tshauv, steatite, quartz, petuntse, thiab alabaster.
YCeramic yog dab tsi?
Ceramic tam sim no tau dhau los ua ib qho ntawm cov khoom tseem ceeb hauv peb txoj haujlwm niaj hnub; cov khoom siv ceramic muaj xws li cov vuas, cib, phaj, iav, thiab chav dej. Ceramic kuj tuaj yeem pom nyob rau hauv watches, snow skies, tsheb, xov tooj, chaw shuttles, dav hlau thiab cov khoom siv xws li enamel coatings. Nws yog inorganic, non-metallic khoom nrog ntau ntau yam. Piv txwv li, nyob ntawm txoj kev tsim khoom, ceramics tuaj yeem yog cov khoom siv ntom ntom lossis cov khoom siv hnyav. Feem ntau, ceramic yog cov khoom siv tawv, tab sis nws yog nkig. Ceramics muaj qee yam khoom zoo xws li hluav taws xob conductivity uas tso cai rau hluav taws xob hla cov khoom siv. Hauv qhov sib piv, nws tuaj yeem cuam tshuam lub insulator, uas tsis ntws hluav taws xob los ntawm cov khoom siv. Tsis tas li ntawd, qee cov ceramics tuaj yeem pom cov khoom siv hluav taws xob thiab cov khoom sib nqus.

Qhov txawv ntawm Ceramic thiab Porcelain yog dab tsi?
Kev tsim cov txheej txheem ceramic thiab cov plooj (porcelain)
Porcelain: Cov txheej txheem tsim cov plooj (porcelain) muaj rau lub ntsiab lus tseem ceeb. Nws pib nrog crushing thiab sib tsoo cov ntaub ntawv raw mus rau qhov xav tau loj siv ntau yam khoom siv. Tom qab ntawd, cov ntaub ntawv loj dhau raug tshem tawm los ntawm kev tshuaj ntsuam lossis sieving. Tom qab ntawd, dej yog ntxiv kom tau qhov xav tau sib xws. Tom ntej no, lub cev ntawm cov porcelain yog tsim; cov txheej txheem no txawv nyob ntawm seb hom khoom siv. Cov khoom tsim tau raug rho tawm haujlwm ntawm qhov kub thiab txias, kom vaporize volatile contaminants thiab txo qis shrinkage thaum tua. Qhov no yog hu ua bisque firing. Ob txheej txheem kawg yog glazing thiab tua.
Ceramic: Cov khoom siv raw ntawm cov ceramic yog av nplaum, av av, hmoov, thiab dej. Tag nrho cov khoom xyaw no sib tov zoo thiab zoo li tus xav tau. Cov ntaub ntawv zoo li raug rho tawm ntawm qhov kub ntawm qhov kub hauv qhov cub. Feem ntau, cov ntaub ntawv ceramic yog them rau cov khoom siv zoo nkauj, cov ntaub ntawv tsis muaj dej hu ua glazes.
Siv Ceramic thiab Porcelain
Porcelain: Cov khoom siv plooj (porcelain) yog siv los ua cov ntaub ntawv insulating, cov khoom siv hauv tsev, cov khoom siv hauv chav dej thiab hauv cov khoom siv nrov nrov.
Ceramic: Cov ntaub ntawv porcelain yog siv los ua cov khoom siv xws li cib, kav dej, thiab hauv pem teb thiab phab ntsa. Tsis tas li ntawd, nws kuj tseem siv rau hauv cov khoom siv hluav taws xob, cov hluav taws xob hluav taws xob, cov khoom siv hluav taws xob, cov tais diav, cov tais diav thiab cov khoom siv engineering.
Khoom Ceramic thiab Porcelain
Porcelain: Cov ntaub ntawv plooj (porcelain) yog qhov ruaj khov, tiv taus xeb thiab impermeable.
Ceramic: Cov khoom siv yog hais los ntawm cov qauv atomic scale; hom atoms tam sim no, hom kev sib txuas ntawm cov atoms, thiab txoj kev uas cov atoms tau ntim ua ke. Hom kev sib txuas ntau tshaj plaws hauv cov ntaub ntawv ceramic yog ionic thiab covalent bonds. Feem ntau, cov ntaub ntawv Ceramic muaj ntau yam khoom, tab sis qee yam ntawm cov khoom muaj npe hauv qab no.
