Hauv kev lag luam niaj hnub no, cov cuab yeej siv feem ntau ntsib qhov chaw ua haujlwm hnyav, thiab hnav thiab tsim kua muag tau dhau los ua qhov tseem ceeb cuam tshuam rau kev tsim khoom thiab cov nqi.Silicon carbide ceramic hnav-resistant hauv ob sab phlu, raws li cov khoom siv ua haujlwm siab, yog maj mam tawm thiab muab cov kev daws teeb meem zoo heev rau ntau qhov chaw lag luam. Niaj hnub no, cia peb delve rau hauv cov hnav-resistant hauv ob sab phlu ntawm silicon carbide ceramics.
1, Lub 'superpower' ntawm silicon carbide ceramics
Silicon carbide (SiC) ceramics yog cov khoom sib xyaw ua ke ntawm ob lub ntsiab lus, silicon thiab carbon. Txawm tias nws yooj yim muaj pes tsawg leeg, nws muaj amazing kev ua tau zoo.
1. Hardness tawg: Lub hardness ntawm silicon carbide ceramics tsuas yog me ntsis inferior rau lub hardest pob zeb diamond nyob rau hauv cov xwm. Qhov no txhais tau hais tias nws tuaj yeem yooj yim tiv thaiv kev khawb thiab txiav ntawm ntau yam nyuaj, thiab tseem muaj kev ruaj ntseg nyob rau hauv qhov chaw hnav khaub ncaws siab, ib yam li muab ib txheej ntawm cov cuab yeej tawv tawv ntawm cov khoom siv.
2. Hnav tsis kam thiab kev tsim ua haujlwm: Nrog nws cov hardness ultra-siab thiab cov qauv siv lead ua tshwj xeeb, silicon carbide ceramics muaj kev hnav zoo heev. Raws li tib lub sijhawm hnav, nws tus nqi hnav qis dua li cov khoom siv hlau ib txwm siv, ua kom lub neej ntev ntawm cov cuab yeej siv tau zoo thiab txo lub sijhawm thiab cov nqi poob los ntawm kev hloov khoom siv ntau zaus.
3. Qhov kub thiab txias tsis kam: Silicon carbide ceramics kuj muaj qhov kub thiab txias tsis kam thiab tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev ntawm qhov kub ntawm 1400 ℃ lossis siab dua. Qhov no ua rau nws ua lub luag haujlwm tseem ceeb hauv high-temperature industrial fields xws li steel smelting, thermal power generation, thiab lwm yam. Nws yuav tsis deform, soften los yog poob nws thawj qhov kev ua tau zoo vim qhov kub thiab txias.
4. Muaj zog tshuaj lom neeg ruaj khov: Tsuas yog qee yam khoom siv xws li hydrofluoric acid thiab concentrated phosphoric acid, silicon carbide ceramics muaj zog tiv taus rau feem ntau cov acids, muaj zog hauv paus, thiab ntau yam hlau molten, thiab lawv cov khoom siv tshuaj muaj zog heev. Hauv kev lag luam xws li tshuaj lom neeg thiab roj av, ntsib ntau yam xov xwm corrosive, nws tuaj yeem tiv thaiv cov khoom siv los ntawm corrosion thiab ua kom cov khoom zoo.
2, Daim ntawv thov scenarios ntawm silicon carbide ceramic hnav-resistant hauv ob sab phlu
Raws li kev ua tau zoo tshaj plaws uas tau hais los saum no, silicon carbide ceramic hnav-resistant hauv ob sab phlu tau siv dav hauv ntau qhov chaw lag luam.
1. Kev Mining: Thaum lub sij hawm kev thauj mus los ntawm cov ore, cov khoom xws li cov kav dej khoov thiab cov chutes muaj kev cuam tshuam rau kev kub ceev thiab kev sib txhuam los ntawm cov khoom ore, uas ua rau hnyav hnyav thiab tsim kua muag. Tom qab txhim kho silicon carbide ceramic hnav-tiv taus hauv ob sab phlu, hnav tsis kam ntawm cov khoom siv no zoo heev, thiab kev pabcuam lub neej tuaj yeem txuas ntxiv los ntawm ob peb lub hlis mus rau ntau xyoo, txo cov khoom siv tu lub sijhawm thiab txhim kho kev tsim khoom.
2. Fais fab kev lag luam: Txawm hais tias nws yog cov hmoov paug pov tseg thiab pneumatic tshauv tshem tawm ntawm thermal fais fab nroj tsuag, los yog cov hmoov xaiv tshuab hniav thiab cyclone separator liners ntawm cov cement nroj tsuag, lawv txhua tus ntsib ib tug loj npaum li cas ntawm plua plav yaig thiab hnav. Silicon carbide ceramic hnav-resistant hauv ob sab phlu, nrog nws zoo heev hnav tsis kam, txo cov khoom siv coj tus nqi, ncua kev pab cuam lub neej ntawm cov cuab yeej, thiab kuj txo downtime los ntawm cov khoom ua tsis tau tejyam, kom ruaj khov kev lag luam ntawm lub hwj chim thiab cement ntau lawm.
3. Kev lag luam tshuaj: Kev tsim tshuaj lom neeg feem ntau cuam tshuam nrog ntau yam corrosive media xws li cov kua qaub thiab alkalis, thiab cov khoom siv kuj yuav muaj kev sib txawv ntawm kev hnav thiab tsim kua muag thaum ua haujlwm. Silicon carbide ceramic hnav-resistant hauv ob sab phlu yog ob qho tib si corrosion-resistant thiab hnav-resistant, thiab tuaj yeem hloov kho kom haum rau qhov chaw ua haujlwm nyuaj, ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm cov khoom siv tshuaj. Hauv cov xwm txheej xws li lithium roj teeb ntau lawm uas yuav tsum tau muaj cov khoom siv purity siab heev, nws tseem tuaj yeem zam cov hlau tsis huv thiab ua kom cov khoom zoo.
Silicon carbide ceramic hnav-resistant hauv ob sab phlu muab txhim khu kev qha hnav-resistant tiv thaiv rau cov khoom siv nrog nws cov kev ua tau zoo heev, dhau los ua tus pab cuam muaj zog rau ntau qhov kev lag luam los txhim kho kev tsim khoom thiab txo cov nqi. Yog tias koj lub tuam txhab tseem tab tom ntsib cov cuab yeej siv thiab tsim kua muag, koj tuaj yeem txiav txim siab xaiv peb cov silicon carbide ceramic hnav-tiv taus hauv ob sab phlu los pib tshooj tshiab hauv kev tsim khoom tau zoo!
