Qhov sib txawv ntawm ceramics thiab precision ceramics

Qhov sib txawv ntawm ceramics thiab precision ceramics

Cov hlau, cov ntaub ntawv organic, thiab ceramics yog kev xa mus rau raws li "peb cov ntaub ntawv loj". Lub sij hawm ceramics tau hais tias tau muaj keeb kwm los ntawm Keramos, cov Greek lo lus rau cov av nplaum rho tawm. Ameslikas xa mus rau ceramics, tsis ntev los no, lub sij hawm ceramics pib siv los xa mus rau cov ntaub ntawv tsis yog xim hlau thiab inorganic thiab cov khoom siv hluav taws xob, iav, thiab xis mas. Rau cov laj thawj saum toj no, ceramics tam sim no tau txhais tias yog "cov khoom siv uas tsis yog xim hlau lossis cov ntaub ntawv kho kom sov thiab raug rau kev tsim khoom".

Among ceramics, high performance and high precision are required for ceramics used in various industrial purposes, including the electronics industry. Yog li ntawd, lawv tam sim no hu ua "cerision ceramics" txhawm rau muab piv nrog cov khoom siv dog dig los ntawm cov khoom ntuj xws li av nplaum thiab silica. sib txawv. Kev nplua khoom nplua yog cov khoom siv hluav taws xob siab siv "nruj me ntsis xaiv hmoov" thiab "tau hloov kho cov tshuaj lom neeg".

Cov ntaub ntawv raw thiab kev tsim cov qauv sib txawv sib txawv
Cov khoom siv raw siv nyob rau hauv Ceramics yog cov zaub mov ntuj, thiab cov neeg siv nyob rau hauv precision ceramics yog qhov ua kom huv si cov khoom siv raw.

Cov khoom lag luam tej nroj tsuag muaj cov yam ntxwv ntawm cov khoom siv tawv tawv muaj zog, thiab cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam. Ntawm lub hauv paus ntawm cov khoom saum toj no, cov ceramics saum toj no muaj ntau cov tshuab, hluavtaws, tshuaj lom neeg, thiab cov haujlwm muaj zog ntau. Tam sim no, precision ceramics yog dav siv nyob rau hauv ntau thaj teb, tsheb, cov ntaub ntawv kev sib txuas lus, thiab kev saib xyuas thiab kho mob. Qhov sib txawv ntawm cov lis dej num ib txwm muaj xws li ceramics thiab cov ceramics tsuas yog nyob ntawm cov khoom nyoos thiab lawv txoj kev tsim khoom. Cov kev coj noj coj ua yog tsim los ntawm kev sib xyaw cov zaub mov ntuj xws li cov av nkos, feldspar, thiab av nplaum, tua lawv. Nyob rau hauv kev sib piv, zoo ceramics siv tau zoo heev cov ntaub ntawv, khoom siv rawial raw ua synthesized los ntawm kev kho tshuaj lom neeg, thiab cov tebchaw uas tsis muaj nyob hauv cov xwm. Los ntawm kev tsim cov ntawv sau saum toj no, cov tshuaj muaj cov khoom xav tau tuaj yeem tau txais. Tsis tas li ntawd, cov khoom npaj cov khoom ntim tau tsim los rau hauv cov khoom lag luam muaj txiaj ntsig zoo thiab cov haujlwm muaj zog los ntawm kev tsim cov txheej txheem xws li molding, thiab sib tsoo.

Kev faib tawm:

1. Cov tais diav thiab Ceramics

1.1 earthenware

Ib lub thawv unglazed ua los ntawm kneading av nplaum, molding nws thiab tua nws ntawm qhov kub tsawg (ncig 800 ° C). Cov no suav nrog Jomon-style earthenware, YAYOi hom earthenware, tsis tau pom los ntawm nruab nrab thiab ze East hauv 6000 BC thiab lwm yam. Cov khoom tam sim no siv yog tsuas yog liab-xim av paj lub lauj kaub, qhov cub liab, qhov cub, lim dej, dej lim dej, thiab lwm yam.

1.2 phav phav

Nws raug rho tawm haujlwm ntawm qhov kub siab dua (1000-1250 ° C) tshaj li earthenware, thiab nws muaj cov khoom nqus dej thiab yog cov khoom siv rho tawm uas siv tau tom qab glazing. Cov no suav nrog Sueki, Rakuyaki, Maice, thiab lwm yam Tam sim no cov khoom siv tau dav ntau, tableware, cov vuas thiab lwm yam.

1.3 plooj (porcelain

Cov khoom lag luam tua hluav taws uas tau muaj kuab heev tom qab ntxiv silica thiab feldspar rau high-purity av nplaum (lossis mudstone), sib xyaw, moulding. Muaj yeeb yuj glazes siv. Nws tau tsim nyob rau lub sijhawm feudal (7th thiab 8th thiab thib 8 xyoo) ntawm Tuam Tshoj xws li Suynasy thiab Tang dynasty thiab kis tau rau lub ntiaj teb. Muaj feem ntau jingdezhen, arita ware, seto ware thiab li ntawd. Cov khoom uas tau siv dav tam sim no feem ntau yog suav nrog tabsware, insulators, kos duab thiab kos duab, cov vuas dai thiab lwm yam.

2. Refractories

Nws yog molded thiab raug rho tawm haujlwm los ntawm cov ntaub ntawv uas tsis cuam tshuam ntawm qhov kub. Nws yog siv los ua kom sov rau cov hlau smelting, hlau ua thiab iav zoo nkauj.

3. Iav

Nws yog cov khoom khov kho tsim los ntawm cov cua kub thiab melting raw cov ntaub ntawv xws li silica, limestone thiab dej qab.

4. Maas

Ib cov hmoov tau los ntawm kev sib xyaw ua ke los ntawm kev sib xyaw ua ke thiab silica, calcining, thiab ntxiv gypsum. Tom qab ntxiv cov dej, cov pob zeb thiab xuab zeb tau ua ke ua ke los ua pob zeb.

5. Precision Industrial Ceramic

Kev nplua khoom zoo yog cov khoom siv siab los ntawm "siv xaiv lossis cov khoom siv raw tshuaj txhuas, finely hloov kho cov tshuaj lom neeg" + "nruj me ntsis tsim qauv kev tsim khoom". Piv nrog tsoos ceramics, nws muaj ntau zog zog, yog li nws tau siv dav hauv ntau yam kev siv, cov tsheb, thiab kev lag luam tshuab, thiab kev lag luam,. Kev nplua cov khoom zoo raug hu ua ceramics thiab kev tshaj lij ceramics rau ib pliag.
