Hauv cov txheej txheem thauj mus los tseem ceeb ntawm kev tsim khoom lag luam, cov xwm txheej ua haujlwm nyuaj xws li kev yaig ntawm cov khoom siv, kev xeb nruab nrab, kub siab thiab siab siab yeej ib txwm yog cov teeb meem "laus thiab nyuaj" uas txwv tsis pub ua haujlwm zoo ntawm cov tuam txhab. Cov kav hlau lossis yas ib txwm muaj teeb meem xws li kev hnav, kev xau, kev xeb, kev hloov pauv, kev thaiv, thiab kev tawg thaum siv ntev. Qhov no tsis yog tsuas yog yuav tsum tau kaw thiab hloov pauv ntau zaus, ua rau cov nqi kho dua tshiab nce ntxiv, tab sis kuj tseem yuav ua rau muaj kev pheej hmoo kev nyab xeeb xws li kev xau ntawm cov khoom siv thiab kev puas tsuaj ntawm cov khoom siv, ua rau "kev phom sij zais" ntawm cov kab ntau lawm. Kev tshwm sim ntawmsilicon carbide hnav-resistant yeeb nkab, nrog nws cov txiaj ntsig zoo ntawm cov khoom siv, muab kev daws teeb meem tshiab rau kev thauj mus los hauv kev lag luam thiab tau dhau los ua tus neeg nyiam "hardcore protector" hauv ntau yam lag luam.
Silicon carbide nws tus kheej yog ib qho khoom siv inorganic uas tsis yog hlau uas muaj qhov nyuaj heev, thib ob tsuas yog pob zeb diamond. Nws kuj muaj cov khoom siv tshuaj lom neeg ruaj khov thiab tsis yooj yim cuam tshuam nrog cov xov xwm corrosive xws li acid thiab alkali. Kev vam khom rau cov txheej txheem molding thiab cov txheej txheem sib xyaw ua ke, cov kav dej silicon carbide hnav-resistant siv tag nrho cov txiaj ntsig ntawm cov khoom siv no - phab ntsa sab hauv yog du thiab ntom, uas tuaj yeem tiv taus kev yaig ceev ntawm cov ntaub ntawv tawv xws li ore slurry, fly ash, thiab cov khib nyiab metallurgical, txo kev hnav thiab tsim kua muag, thiab tiv taus kev yaig ntawm ntau yam xov xwm corrosive hauv kev lag luam tshuaj lom neeg, tshem tawm qhov kev pheej hmoo ntawm kev xau. Txawm hais tias nws yog kev thauj mus los slurry hauv kev khawb av, kev thauj mus los ntawm cov khoom siv desulfurization thiab denitrification hauv kev lag luam fais fab, lossis kev thauj mus los ntawm acid-base hauv kev lag luam tshuaj lom neeg, nws tuaj yeem hloov kho rau ntau yam kev ua haujlwm thiab ua haujlwm ruaj khov rau lub sijhawm ntev.
Piv rau cov kav dej ib txwm muaj, cov txiaj ntsig ntawm cov kav dej silicon carbide hnav-resistant mus deb tshaj qhov ntawd. Cov kav dej hlau ib txwm muaj hnyav, nyuaj rau teeb tsa, thiab yooj yim rau oxidation thiab xeb, uas tuaj yeem cuam tshuam rau lawv lub neej kev pabcuam; cov kav dej yas ib txwm muaj kev tiv thaiv cua sov tsis zoo thiab tsis muaj zog tiv thaiv kev cuam tshuam, ua rau nws nyuaj rau hloov mus rau qhov chaw ua lag luam nyuaj. Cov kav dej silicon carbide hnav-resistant tsis yog tsuas yog sib dua hauv qhov hnyav, yooj yim dua rau kev thauj mus los thiab teeb tsa, thiab txo cov nqi tsim kho, tab sis kuj muaj qhov kub thiab txias zoo heev. Lawv tuaj yeem tswj tau qhov ruaj khov ntawm cov qauv hauv qab cov xwm txheej hnyav xws li hloov pauv kub siab thiab qis thiab kev co hnyav, thiab tsis yooj yim deformed lossis tawg. Qhov tseem ceeb tshaj, nws phab ntsa sab hauv du tuaj yeem txo qhov tsis kam ntawm cov khoom xa tuaj, zam kev sib sau ua ke thiab thaiv cov khoom, xyuas kom meej tias kev ua haujlwm tas mus li thiab du ntawm lub kaw lus xa khoom, txo lub sijhawm tsis ua haujlwm rau kev saib xyuas, thiab tsis ncaj qha txhim kho kev ua haujlwm ntawm lub tuam txhab.
Hauv qhov kev hloov pauv tam sim no ntawm kev txhim kho kev lag luam ntsuab thiab qis carbon, qhov "kev ua haujlwm ntev" ntawm cov kav dej silicon carbide hnav-resistant yog nyob rau hauv kab nrog cov kev xav tau ntawm cov lag luam kom txo cov nqi thiab ua kom muaj txiaj ntsig zoo. Nws lub neej kev pabcuam ntau dua li ntawm cov kav dej ib txwm muaj, uas tuaj yeem txo qhov zaus ntawm kev hloov pauv kav dej, txo cov khoom siv raw thiab kev tsim cov khib nyiab, thaum txo cov neeg ua haujlwm thiab cov khoom siv hauv cov txheej txheem txij nkawm, txuag cov nqi ua haujlwm thiab kev txij nkawm rau cov lag luam thiab pab ua tiav kev tsim khoom ntsuab. Los ntawm kev khawb av mus rau hluav taws xob, los ntawm kev lag luam tshuaj lom neeg mus rau metallurgy, cov kav dej silicon carbide hnav-resistant maj mam hloov cov kav dej ib txwm muaj thiab dhau los ua qhov kev xaiv tseem ceeb rau kev txhim kho kev thauj mus los hauv kev lag luam, tso ib txoj kab tiv thaiv zoo rau kev nyab xeeb ntawm kev tsim khoom hauv ntau yam lag luam thiab txhaj tshuaj muaj zog rau hauv kev txhim kho zoo ntawm kev lag luam niaj hnub.
