Ceramic raj thiab qhov tshwj xeeb-zoo li tus

Ceramic raj thiab qhov tshwj xeeb zoo li qhov Featured duab

Lus piav qhia luv luv:

Hnav resistant ceramics uas yog tsim los ntawm tsawg kawg yog 90% Al2O3 yog cov feem ntau siv nyob rau hauv lub ntiaj teb no niaj hnub no.

Peb cov khoom yog tsim los ntawm nruj me ntsis xaiv alumina hmoov nrog cov khoom me me qhov ntau thiab tsawg CaO cov ntsiab lus. Hnav resistant ceramics tuaj yeem ua los ntawm cov xovxwm qhuav los yog isostatic nias txheej txheem thiab tom qab ntawd sintering lawv ntawm qhov kub thiab txias hauv qhov cub.Lawv yog cov ntaub ntawv tsim nyog rau cov khoom siv coj los siv vim qhov ntev, qhov ntom ntom, siab alumina cov ntsiab lus, zoo flatness thiab ruaj khov zoo.

Piv txwv ntawm Kev Siv

Lus Cim: Peb tuaj yeem ua alumina hnav pobzeb raws li koj xav tau.

Nta

Siab hardness

Rockwell hardness ntawm siab alumina ceramics yog mus txog HRA80-90 uas yog thib ob tsuas yog pob zeb diamond thiab deb tshaj hnav-resistant steel stainless.

Zoo heev hnav tsis kam

Kev hnav tsis kam ntawm siab alumina ceramics yog 266 npaug ntawm cov hlau manganese thiab 171.5 npaug ntawm cov chromium cam khwb cia hlau siab. ua hauj lwm tej yam kev mob.

Corrosion kuj

High alumina ceramics yog inorganic oxides nrog cov qauv molecular ruaj khov thiab tsis muaj electrochemical corrosion, yog li lawv tuaj yeem tiv taus yaig ntawm cov kua qaub, alkali, ntsev tov thiab cov kuab tshuaj organic.

Thermostability

Ua hauj lwm kub ntawm siab alumina ceramics yuav siab li 1400 ℃.

Zoo tus kheej-lubricity

High alumina ceramics muaj cov khoom ntawm nws tus kheej-lubricity thiab inadhesion, qhov roughness tsuas yog 1/6 ntawm cov kav hlau steel yog li tsis tshua muaj dej tsis kam.

Lub teeb nyhav

Qhov ceev ntawm high alumina ceramics yog hais txog 3.6g / cm3, uas tsuas yog ib nrab ntawm cov hlau, yog li yooj yim rau kev tsim kho thiab installation.

Hnav cov kev daws teeb meem peb muab

Qhov no yog txheej txheem nyuaj.Our engineers nkag siab txog cov teeb meem hnav thiab qhia meej

kev daws teeb meem kom tau raws li koj qhov chaw ua haujlwm.Cov khoom siv, kam rau ua, flatness, txuas txoj kev, thiab cov nqi ntawm cov khoom yog suav tias yog nyob rau hauv ib tug hnav s
