Kev lag luam cement yeej ib txwm ntsib ob qhov kev sib tw loj:kev siv hluav taws xob siabthiabhnyav hnav ntawm cov hlau.
Txhua xyoo hauv Suav teb ib leeg, ntau dua2 lab tons ntawm hlauyog hnav tawm thiab hloov. Ntawm lawv,sib tsoo pob siv li 55%ntawm tag nrho hnav, thiabliners account rau lwm 11%.
Nyob rau tib lub sijhawm, chromium paug hauv cov cement tau dhau los ua kev txhawj xeeb ntxiv rau tib neeg kev noj qab haus huv thiab ib puag ncig. Nrog cov qauv nruj dua hauv lub tebchaws nyob rau hauv qhov chaw, ntau cov nroj tsuag tau pib nrhiav cov ntaub ntawv huv thiab ruaj khov dua.
Qhov no yog qhov chaw ceramics tuaj.
Vim li cas Ceramics? Vim Lawv Nyuaj Siab Heev
Hnav- cov ceramics resistant feem ntau yog ua los ntawm alumina.
Thaum cov ntsiab lus alumina nce siab tshaj 90%, peb hu nwscorundum ceramic-thiab nws cov hardness siab heev,hauv qab pob zeb diamond.
Qhov ntawd ua rau nws hloov tau zoo rau siab -chrome cam khwb cia hlau siv hauv kev sib tsoo cement.
Tab sis Tsis yog Alumina Brittle? Peb daws qhov ntawd.
Ntshiab alumina yog ib qho nyuaj heev, tab sis nws kuj tuaj yeem ua nkig. Hauv cov cement mills, cov kev cuam tshuam muaj zog tuaj yeem ua rau tawg.
Txhawm rau kho qhov no, zirconia ntxiv rau alumina. Qhov no tsimZTA (Zirconia Toughened Alumina), uas muaj ob:
siab hardness
zoo dua toughness thiab cuam tshuam tsis kam
Raws li cov khoom siv no, peb tsimceramic sib tsoo pobthiabZTA ceramic lineruas:
txo hwj chim noj
heev txo cov hlau hnav
tshem tawm cov kab mob chromium
muab kev pab lub neej ntev dua
Pov thawj nyob rau hauv Dawb Cement thiab Xim Cement Cog
Ob peb xyoos dhau los, ceramic sib tsoo xov xwm thiab ZTA liners tau siv rau hauv cov cement dawb thiab cov xim cement ntau lawm nrog cov txiaj ntsig zoo heev.
Cov neeg siv tau pom:
ntau dua kev sib tsoo efficiency
qis zog siv
tsawg hloov thiab downtime
ntxuav, chromium -dawb cement
Vim yog cov txiaj ntsig zoo no, ntau thiab ntau cov cement nroj tsuag hloov los ntawm siab -chrome cam khwb cia hlau rau cov ntaub ntawv ceramic.
Ib qho tshuaj ntxuav thiab ua kom zoo dua
Raws li kev lag luam txav mus rau ntsuab thiab muaj zog ntau dua - cov khoom siv tau zoo, cov ntaub ntawv ceramic tau dhau los ua qhov kev xaiv zoo tshaj plaws rau ntau lub tuam txhab cement.
Lub neej ntev dua, xoom chromium, thiab kev txuag nqi tiag tiag -ceramics yog pab cov cement kev lag luam hloov mus rau lub neej yav tom ntej.
