Hnav-Resistant Ceramic Pipes: Lub Hwj Chim Sib Nraus - Vim Li Cas Alumina Ceramic Pipes tuaj yeem tiv taus cov khoom yaig?

Hardness hais rau nws tus kheej
Alumina ceramic kav yog tsim los ntawm tsawg kawg 90% Al₂O₃ thiab muaj Mohs hardness ntawm 8.5-9, thib ob tsuas yog pob zeb diamond. Nyob rau hauv sib piv, zoo tib yam steel kav muaj ib tug hardness ntawm kwv yees li 4-5; Raws li kev ua haujlwm zoo ib yam, tus nqi ntawm cov cement mortar yog 8-12 npaug ntawm cov kav dej alumina ceramic. Qhov no txhais tau hais tias thaum thauj cov slurries uas muaj quartz xuab zeb, cov phab ntsa sab hauv ntawm cov kav dej ceramic muaj kev ua haujlwm qeeb qeeb thiab cov khoom siv poob qis dua.

Microstructure Dictates Hnav Resistance
Cov kav dej ceramic uas tsim los ntawm qhov siab -kub sintering feature nruj nreem khi cov nplej nrog qhov tsis zoo ntawm qhov porosity. Thaum raug cov khoom impingement, qhov saum npoo yog resistant rau kev txiav txim ntawm cov khoom nyuaj. Kev sim cov ntaub ntawv qhia meej meej tias kev thauj cov slurry ntawm qhov khiav ceev ntawm 3-5 meters ib ob, qhov sib npaug txhua xyoo hnav tuab rau 95% alumina ceramic kav tsuas yog 0.1-0.3 hli xwb- ib daim duab qis dua qhov hnav txwv uas yuav tsum tau hloov cov kav hlau.

Cov ntsiab lus tseem ceeb rau kev xaiv
1. Wear resistance varies with alumina content. Grades with >92% alumina cov ntsiab lus zoo dua rau siab - hnav kev ua haujlwm.

2. Cov kav dej ceramic yog cov nkig; Yog li ntawd, kev cuam tshuam nruj yuav tsum tau zam thaum lub sijhawm teeb tsa. Kev siv cov elastic sealing rings nrog flanged kev sib txuas yog pom zoo kom txo qis cov ntsiab lus kev ntxhov siab.

Kev nkag siab txog cov ntsiab lus tseem ceeb no yuav pab koj txiav txim siab paub ntau ntxiv thaum xaiv cov cuab yeej siv rau ntawm - daim ntawv thov ntawm qhov chaw.
