Kev siv tshuab

Kaolin tau dhau los ua cov khoom siv ntxhia tsim nyog rau ntau qhov kev lag luam xws li ntawv ua, ceramics, roj hmab, tshuaj, txheej, tshuaj thiab kev tiv thaiv hauv tebchaws.

Ceramic kev lag luam yog qhov ntxov tshaj daim ntawv thov ntawm kaolin, ntau qhov kev lag luam. Qhov dav dav npaum li cas yog 20% ~ 30% ntawm cov mis. Lub luag hauj lwm ntawm kaolin nyob rau hauv ceramics yog qhia A1203, uas yog conducive rau tiam ntawm mullite, txhim kho nws cov tshuaj stability thiab sintering lub zog, thiab decompose kaolin mus rau hauv mullite nyob rau hauv lub firing txheej txheem, tsim lub ntsiab ncej ntawm lub zog ntawm lub billet, uas. tuaj yeem tiv thaiv qhov deformation ntawm cov khoom, ua kom qhov kub hnyiab tau dav dua, thiab tseem ua rau cov billet muaj qee yam xim dawb. Nyob rau tib lub sijhawm, kaolin muaj qee yam plasticity, adhesion, ncua kev kawm ntawv thiab kev sib koom ua ke, muab cov av nkos plooj (porcelain), porcelain glaze formability zoo, yog li cov av nkos ceramic yog qhov zoo rau kev tig thiab grouting, yooj yim rau kev tsim. Yog tias siv rau hauv cov xov hlau, nws tuaj yeem ua rau muaj kev rwb thaiv tsev thiab txo dielectric poob.

Ceramics tsis tsuas yog muaj cov kev cai nruj rau cov yas, khi, ziab kom qhuav, ziab lub zog, sintering shrinkage, sintering zog, refractoriness thiab post-firing whiteness ntawm kaolin, tab sis kuj muaj cov tshuaj muaj zog, tshwj xeeb tshaj yog muaj hlau, titanium, tooj liab, chromium. , manganese thiab lwm yam xim, uas txo cov xim dawb tom qab tua thiab tsim cov pob.

Lub granularity yuav tsum tau ntawm kaolin feem ntau finer, qhov zoo dua, yog li ntawd cov porcelain av nkos muaj zoo plasticity thiab qhuav lub zog, tab sis rau cov txheej txheem casting yuav tsum tau ceev nrooj, accelerating lub casting ceev thiab lub cev qhuav dej ceev, nws yog ib qhov tsim nyog yuav tau ua kom cov particle loj. cov khoom xyaw. Tsis tas li ntawd, qhov sib txawv ntawm cov degree ntawm crystallization ntawm kaolinite hauv kaolinite kuj tseem cuam tshuam rau cov txheej txheem kev ua tau zoo ntawm cov plooj (porcelain billet). Yog hais tias lub degree ntawm crystallization yog zoo, lub plasticity thiab bonding peev xwm yog tsawg, lub qhuav shrinkage yog txo, lub sintering kub yog siab, thiab cov impurity cov ntsiab lus kuj txo. Ntawm qhov tsis sib xws, nws cov plasticity yog siab, qhov ziab ziab yog qhov loj, qhov kub ntawm sintering yog tsawg, thiab cov ntsiab lus impurity coj los kuj siab.

Physicochemical khoom

Khoom: ntau npub, ntshiab thaum dawb thiab muag heev, xws li muaj impurities tuaj yeem nrog grey, daj, xim av thiab lwm yam xim. Nyob ntawm lub hauv paus chiv keeb, qhov tsos tuaj yeem yog xoob av thaiv thiab ntom pob zeb thaiv.

Qhov ceev: 2.54-2.60g / cm3. Melting point: txog 1785 ℃.

Nrog plasticity, cov av ntub dej tuaj yeem ua rau ntau yam duab tsis tawg, thiab tuaj yeem nyob twj ywm tsis hloov mus ntev.
