Ib qho kev daws teeb meem rau kev hnav siab thiab hnyav hnyav
Lub thoob log excavators yog cov cuab yeej tseem ceeb hauv cov khoom siv tuav ntau, dav siv hauv mining, thee, thiab chaw nres nkoj terminals. Lawv ua haujlwm tsis tu ncua nyob rau hauv tsis tshua muaj abrasive thiab siab - tej yam kev mob cuam tshuam. Qhov kev ua tau zoo ntawm cov liners ncaj qha cuam tshuam rau cov khoom siv lub neej thiab kev ua haujlwm zoo. Alumina ceramic liner tau dhau los ua pov thawj kev daws teeb meem rau cov teeb meem no.
Cov xwm txheej ua haujlwm hnyav ntawm thoob lub log liner
Hauv kev siv mining, liners ntsib kev sib xyaw ua ke ntawm cov xwm txheej hnyav:
Heavy abrasion:Cov ntaub ntawv nyuaj thiab ntse xws li ore thiab thee tsim cov zawv zawg thiab dov tsis tu ncua, ua rau cov khoom siv sai sai ntawm cov khoom siv hlau.
Muaj zog cuam tshuam:Cov pob loj loj poob los ntawm qhov siab los yog sib tsoo nrog cov khoom ua rau muaj kev cuam tshuam loj, ua rau tawg lossis deformation.
Corrosion thiab oxidation:Moist, acidic, alkaline, los yog siab - qhov kub thiab txias ib puag ncig ua rau muaj kev xeb ntawm cov hlau sib xws.
Cov xwm txheej no feem ntau ua rau lub neej ua haujlwm luv luv, hloov pauv tsis tu ncua, nce nqi txij nkawm, thiab txo qhov system stability.
Hnav Mechanism
Liners feem ntau raug kev txom nyem los ntawm kev sib xyaw ua kesiab -stress abrasive hnavthiabcuam tshuam hnav. Cov khoom tawv tawv txiav thiab ua rau qaug zog ntawm daim kab xev, thaum rov muaj kev cuam tshuam pib thiab nthuav dav micro- tawg, ua kom cov kab tsis ua haujlwm.
Vim li cas Alumina Ceramic Liners yog qhov kev xaiv zoo tshaj plaws
Alumina ceramic liners yog engineered los tiv taus huab cua abrasive thiab tej yam kev mob. Lawv cov txiaj ntsig tseem ceeb suav nrog:
Exceptional hnav tsis kam
Nrog hardness saum HRA 85, alumina ceramics muaj kev hnav tsis kam ntau lub sij hawm siab dua li manganese hlau, ua kom ntev liner lub neej.
Txhim kho qhov cuam tshuam toughness
High -cov ntaub ntawv ceramic muaj zog nqus lub zog thiab tiv thaiv kev ua haujlwm tsis zoo lossis delamination thaum thauj khoom hnyav.
Zoo tshuaj stability
Alumina ceramics tiv taus acids, alkalis, thiab cov kuab tshuaj, ua rau lawv haum rau qhov chaw ntub dej, kub, lossis corrosive ib puag ncig.
Ceramic liners tuaj yeem ntsia tau los ntawm bolts lossis nplaum nplaum. Rau cov mining mob hnyav nrog kev cuam tshuam loj dua, lub thickness dhau30 mmraug pom zoo kom muaj kev ruaj ntseg thiab ntev - kev ua tau zoo.
