Qhov sib txawv ntawm ceramics thiab precision ceramics
Cov hlau, cov ntaub ntawv organic, thiab ceramics tau sau npe hu ua "peb cov ntaub ntawv loj".Lo lus Ceramics tau hais los ntawm Keramos, lo lus Greek rau av nplaum raug rho tawm haujlwm.Ameslikas xa mus rau ceramics, tsis ntev los no, lo lus ceramics pib siv los xa mus rau cov khoom tsis yog xim hlau thiab inorganic nrog rau cov ntaub ntawv refractory, iav, thiab cement.Rau cov laj thawj saum toj no, ceramics tam sim no tuaj yeem txhais tau tias yog "cov khoom siv uas tsis yog xim hlau lossis cov khoom siv tsis zoo thiab raug kev kub ntxhov hauv cov txheej txheem tsim khoom".
Ntawm cov ceramics, kev ua haujlwm siab thiab kev ua haujlwm siab yog yuav tsum tau siv rau cov ceramics siv ntau lub hom phiaj, nrog rau kev lag luam hluav taws xob.Yog li ntawd, tam sim no lawv hu ua "precision ceramics" txhawm rau muab piv nrog cov ceramics zoo tib yam ua los ntawm cov khoom siv ntuj xws li av nplaum thiab silica.sib txawv.Fine ceramics yog cov khoom siv high-precision ceramics uas tsim los siv "cov khoom siv nruj me ntsis los yog cov khoom sib xyaw ua ke hmoov" los ntawm "cov txheej txheem tsim khoom nruj me ntsis" thiab "tsim kho cov tshuaj muaj pes tsawg leeg".
Cov khoom siv raw thiab kev tsim khoom sib txawv heev
Cov khoom siv raw siv hauv ceramics yog cov ntxhia hauv ntuj, thiab cov khoom siv hauv cov khoom siv ceramics yog cov khoom siv purified heev.
Cov khoom siv ceramic muaj cov yam ntxwv ntawm kev ua haujlwm siab, kev ua haujlwm kub zoo, kev tiv thaiv corrosion, hluav taws xob rwb thaiv tsev, thiab lwm yam Ceramics, cov khoom siv refractory, iav, cement, precision ceramics, thiab lwm yam yog nws cov khoom sawv cev.Raws li lub hauv paus ntawm cov khoom saum toj no, nplua ceramics muaj cov khoom siv zoo heev, hluav taws xob, kho qhov muag, tshuaj, thiab biochemical zog, nrog rau kev ua haujlwm zoo dua.Tam sim no, precision ceramics yog dav siv nyob rau hauv ntau yam xws li semiconductors, tsheb, cov ntaub ntawv kev sib txuas lus, industrial machinery, thiab kev kho mob.Qhov sib txawv ntawm cov tsoos ceramics xws li ceramics thiab nplua ceramics feem ntau yog nyob ntawm cov khoom siv raw thiab lawv txoj kev tsim khoom.Cov tsoos ceramics yog tsim los ntawm kev sib xyaw tej yam ntuj tso xws li av nkos, feldspar, thiab av nplaum, thiab tom qab ntawd molding thiab tua lawv.Hauv qhov sib piv, cov ceramics zoo siv cov khoom siv raw khoom zoo heev, cov khoom siv raw khoom tsim los ntawm kev kho tshuaj, thiab cov tebchaw uas tsis muaj nyob hauv cov xwm txheej.Los ntawm kev tsim cov khoom siv raw li hais saum toj no, ib yam khoom uas muaj cov khoom xav tau tuaj yeem tau txais.Tsis tas li ntawd, cov ntaub ntawv npaj tau tsim los rau hauv cov khoom muaj nqis ntxiv nrog qhov tseeb qhov tseeb thiab muaj zog ua haujlwm los ntawm kev tswj xyuas cov txheej txheem xws li molding, tua, thiab sib tsoo.
Classification ntawm ceramics:
1. Cov tais diav & Ceramics
1.1 Earthenware
Ib lub thawv unglazed ua los ntawm kneading av nplaum, molding nws thiab tua nws ntawm qhov kub thiab txias (nyob ib ncig ntawm 800 ° C).Cov no suav nrog Jomon-style earthenware, Yayoi-type earthenware, unearthed objects from Middle and Near East in 6000 BC thiab hais txog.Cov khoom siv tam sim no feem ntau yog xim liab-xim av paj lauj kaub, cib liab, qhov cub, lim dej, thiab lwm yam.
1.2 Lub khob hliav qab
Nws raug rho tawm haujlwm ntawm qhov kub siab dua (1000-1250 ° C) dua li cov khoom siv hauv av, thiab nws muaj dej nqus thiab yog cov khoom raug rho tawm haujlwm uas siv tom qab glazing.Cov no suav nrog SUEKI, RAKUYAKI, Maiolica, Delftware, thiab lwm yam. Tam sim no cov khoom siv dav siv feem ntau yog cov tshuaj yej teeb, tableware, paj teeb, vuas thiab lwm yam.
1.3 Porcelain
Cov khoom raug rho tawm haujlwm dawb uas tau ua tiav tiav tom qab ntxiv silica thiab feldspar rau cov av nplaum uas muaj purity (los yog av nkos), sib tov, molding, thiab tua.Cov yeeb yuj glazes yog siv.Nws tau tsim nyob rau hauv lub sijhawm feudal (7th thiab 8th centuries) ntawm Tuam Tshoj xws li Sui Dynasty thiab Tang Dynasty thiab kis mus rau lub ntiaj teb no.Muaj feem ntau Jingdezhen, Arita ware, Seto ware thiab hais txog.Cov khoom siv dav siv tam sim no feem ntau suav nrog tableware, insulators, arts thiab crafts, hniav vuas thiab lwm yam.
2. Refractories
Nws yog molded thiab raug rho tawm los ntawm cov ntaub ntawv uas tsis deteriorate nyob rau hauv high kub.Nws yog siv los tsim qhov cub rau hlau smelting, steel ua thiab iav melting.
3. iav
Nws yog amorphous khoom tsim los ntawm cua sov thiab melting raw cov ntaub ntawv xws li silica, limestone thiab soda tshauv.
4. Cement
Cov hmoov tau los ntawm kev sib xyaw limestone thiab silica, calcining, thiab ntxiv gypsum.Tom qab ntxiv dej, cov pob zeb thiab cov xuab zeb tau sib txuas ua ke los ua pob zeb.
5. Precision Industrial Ceramic
Fine ceramics yog high-precision ceramics tsim los ntawm "siv xaiv los yog tsim cov khoom siv raw hmoov, ua kom zoo kho cov tshuaj muaj pes tsawg leeg" + "cov txheej txheem tsim khoom nruj me ntsis".Piv nrog cov tsoos ceramics, nws muaj lub zog muaj zog dua, yog li nws tau siv dav hauv ntau daim ntawv thov xws li semiconductors, tsheb, thiab kev lag luam machinery.Fine ceramics tau hu ua cov ceramics tshiab thiab cov ceramics siab heev rau ib pliag.
