ZTA Ceramic Phaj Ntawv
Kev piav qhia txog khoom
Zirconia Toughened Alumina Ceramic kuj hu ua ZTA ceramic, uas yog xim dawb, yog cov khoom siv sib xyaw ua ke ntawm txhuas oxide thiab 20 ~ 25% zirconium oxide. ZTA Ceramics yog cov khoom siv tshiab tsim tawm hauv xyoo tas los no.
Chemshun ZTA yog ib qho kev txhim kho zoo heev hauv kev muaj zog cuam tshuam thiab kev tawv dua li alumina ceramic. Chemshun ZTA txoj kev tiv thaiv kev hnav yog 2.5 npaug zoo dua li alumina ceramic. ZTA muab lub neej ntev dua ntawm cov khoom siv thiab kev daws teeb meem ntev dua, nws tsim nyog heev rau kev cuam tshuam hnyav thiab cov khoom siv hnav ntawm kev lag luam mining. Tam sim no BHP Australia siv ntau ntawm ZTA Ceramic Liners.
Cov duab thiab hom ntawm ZTA Ceramics
Chemshun ZTA ceramics tuaj yeem tsim ua ceramic hom tiaj tus, arc hom, cube, cylinder, hex tile thiab lwm yam.
Cov khoom siv tshuab tshwj xeeb kuj tau tsim tshwj xeeb nrog cov duab kos CAD.
Yuav kom siv tau ZTA zoo dua, peb feem ntau vulcanize ZTA rau roj hmab thiab hlau thiab ntsia cov bolts rau sab nraub qaum ntawm cov hlau. Peb hu ua kev sib xyaw ua ke li hnav ZTA ceramic roj hmab liner. Cov neeg siv khoom tuaj yeem yooj yim ntsia cov khoom ntawm qhov chaw.
Cov yam ntxwv ntawm ZTA Hnav Cov Khoom Uas Tiv Thaiv Kev Cuam Tshuam:
Muaj zog tiv taus kev cuam tshuam ntau dua li High alumina
Tus nqi qis dua li cov khoom siv zirconia ceramics uas muaj purity
Kev tiv thaiv zoo heev
Kev tiv thaiv corrosion siab
Kev tawg siab tawv
Kev ruaj khov kub siab
