Kev thov loj hlob ntawm tus nqi-txuag kev tiv thaiv kev hnav khaub ncaws thawb cov khoom siv ceramic rau hauv txoj haujlwm tseem ceeb ntawm cov ntaub ntawv hauv ob sab phlu rau cov khoom siv ua khoom lag luam thoob ntiaj teb.
Ceramic coj daim hlau feem ntau yog sintered los ntawm 92% mus rau 95% siab-purity alumina hmoov nyob rau hauv ultra- kub. Ua tsaug rau cov txheej txheem ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom qauv tsim cov qauv tsim ua tiav, cov khoom tiav tiav ua tiav cov hardness zoo heev thiab tsis tshua muaj hnav tsis zoo. Lawv cov kev ua tau zoo yog 8 mus rau 12 npaug ntawm cov hlau manganese tsis tu ncua, thiab lawv nyob twj ywm tsis cuam tshuam los ntawm feem ntau cov kua qaub, alkaline thiab corrosive raw khoom thaum lub sij hawm tas mus li ntau lawm.
Cov neeg tsim khoom muab cov qauv sib txawv nrog rau cov khoom siv monolithic ceramic phaj thiab roj hmab -ceramic composite coj daim hlau. Cov khoom sib xyaw ua ke ua ke nrog cov khoom siv hluav taws xob los tiv thaiv- muaj peev xwm ua kom tawg nrog roj hmab poob siab- nqus cov cuab yeej, ua kom haum rau qhov chaw ua haujlwm nrog cov khoom siv muaj zog xws li hloov pauv hoppers, chutes thiab cyclone separators. Cov khoom puas tuaj yeem hloov pauv hloov pauv ntawm tag nrho cov khoom tawg, ua kom lub sijhawm nres ntau lawm.
Tam sim no, cov ris tsho hnav no tau ua tiav kev lag luam dav dav. Cov tuam txhab mining siv lawv ntawm cov khoom siv ore conveying; cement nroj tsuag txhim kho cov kab hauv cov kav dej nyoos; Thermal fais fab chaw cia siab rau cov khoom rau thee tshauv xa khoom. Cov lus tawm tswv yim qhia tau hais tias cov neeg siv khoom feem ntau txo cov nqi kho txhua xyoo ntau dua 45% tom qab kho dua tshiab.
Cov tuam txhab tsim khoom hauv zos khaws cov txheej txheem tsim khoom thiab muab qhov ntau thiab tsawg, tuab thiab cov duab raws li qhov sib txawv ntawm - qhov yuav tsum tau ua ntawm qhov chaw. Cov kws tshuaj ntsuam xyuas kev lag luam hais txog lub ntiaj teb ceramic hnav phaj kev lag luam yuav tuav ruaj khov txhua xyoo kev loj hlob thaum lub ntiaj teb kev lag luam hloov pauv mus rau kev ua haujlwm siab thiab tus nqi qis.
Raws li cov khoom siv hluav taws xob tshiab thiab cov khoom siv pov tseg rov ua dua tshiab nthuav dav sai, cov phaj hnav ceramic yuav tau txais cov ntawv thov tshwm sim ntau dua thiab txhawb nqa kev lag luam muaj zog hauv xyoo tom ntej.
