Cov kav dej thee pulverized yooj yim hnav, yog li nws raug pom zoo kom siv cov khoom siv ceramic uas tiv taus hnav rau kev tiv thaiv kev hnav

Cov kav dej thee uas raug hluav taws xob feem ntau yuav hnav hnyav heev, tshwj xeeb tshaj yog lub luj tshib, nrog rau cov nqi kho ntau zaus nce ntxiv, yog li daws qhov kev hnav ntawm cov kav dej tau dhau los ua qhov tseem ceeb tshaj plaws.

Peb pom zoo kom siv cov alumina ceramics uas tiv taus hnav xws li cov khoom siv uas tiv taus hnav siab. Cov ceramics uas tiv taus hnav yog ua los ntawm AL2O3 ua cov khoom siv tseem ceeb, cov hlau oxides tsis tshua muaj ua cov kua dej, thiab cov ceramics corundum tshwj xeeb ci ntawm 1,700 degrees kub, nrog Rockwell hardness ntawm HRA80-90, qhov nyuaj thib ob tsuas yog pob zeb diamond, thiab hnav tsis kam sib npaug rau 266 npaug ntawm manganese hlau thiab 171.5 npaug ntawm cov hlau cam khwb cia chromium siab. Cov ceramics uas tiv taus hnav yog cov khoom siv tshwj xeeb uas muaj kev tiv taus hnav siab, tiv taus corrosion thiab tiv taus kub siab. Kev siv cov ceramics uas tiv taus hnav hauv cov kav dej pulverized thee tuaj yeem txo qhov hnav ntawm cov kav dej thiab ua kom lub neej kev pabcuam ntawm cov kav dej ntev dua.

Cov khoom siv ceramic uas tsis hnav tau tuaj yeem ntsia tau rau ntawm lub luj tshib lossis lub tee sab hauv phab ntsa ntawm cov kav dej thee uas raug tsoo kom tiv thaiv cov kav dej ntawm kev hnav cov khoom siv, thiab nws kuj tuaj yeem ua rau cov kav dej uas tsis hnav tau sib xyaw nrog cov khoom siv ceramic thiab hlau. Nws yog qhov tsim nyog heev los daws qhov teeb meem ntawm kev hnav cov kav dej nrog cov khoom siv ceramic uas tsis hnav tau, cov khoom siv ceramic yooj yim rau kev teeb tsa, yuav tsis coj teeb meem thaiv rau cov kav dej, thiab txawm tias tuaj yeem tiv taus kev xeb ntawm cov khoom siv, cov khoom siv ceramic uas tsis hnav tau kuj zoo heev rau cov chaw xeb.

Tsis tas li ntawd,cov khoom siv ceramic uas tsis yooj yim hnav kuj tseem siv tau rau cov li qub, twj tso kua mis thiab lwm yam khoom ntawm cov kav dej thee pulverized kom txhim kho lawv txoj kev hnav tsis kam.

Raws li cov xwm txheej thauj mus los, qhov loj ntawm cov khoom siv, qhov loj ntawm cov kav dej, xaiv cov ntaub pua plag ceramic uas tiv taus kev hnav, kom ua tiav qhov zoo tshaj plaws tiv thaiv kev hnav.
