Hauv ntau lub Hoobkas, qee cov khoom siv tseem ceeb, xws li lub kiv cua, cov chutes, lub luj tshib, lub qhov ncauj ntawm lub twj tso kua mis, thiab lwm yam, feem ntau hnav sai sai vim yog kev puas tsuaj ntawm cov kua dej ceev ceev uas muaj cov khoom khov. Txawm hais tias cov 'cov ntsiab lus yooj yim hnav' no tsis tseem ceeb, lawv cuam tshuam ncaj qha rau kev ua haujlwm zoo thiab zaus kaw ntawm cov khoom siv. Hnub no peb yuav tham txog cov neeg tiv thaiv me me uas tsim tshwj xeeb los "tiv taus" cov kev hnav thiab tsim kua muag no -silicon carbide hnav-resistant blocks.
Tej zaum ib txhia neeg yuav nug tias, vim li cas ho siv "silicon carbide" los ua cov blocks uas tiv taus kev hnav? Cov lus teb yeej yooj yim to taub. Ua ntej, nws yog "nyuaj". Silicon carbide muaj qhov nyuaj heev, thib ob tsuas yog pob zeb diamond, thiab tuaj yeem tiv taus kev yaig ntawm cov khoom me me ceev ceev ntev; Tom ntej no yog 'kev ruaj khov', uas muaj cov khoom siv tshuaj ruaj khov, tiv taus acid thiab alkali corrosion, thiab yuav tsis 'noj' los ntawm ntau yam khoom siv hauv kev lag luam; Ib zaug ntxiv, nws yog 'kub-resistant', uas tuaj yeem ua haujlwm ruaj khov ntawm qhov kub siab dua thiab tsis yooj yim tawg thaum muaj kev hloov pauv kub. Qhov tseem ceeb tshaj plaws, nws muaj qhov chaw du thiab coefficient sib txhuam qis, uas tsis tsuas yog txo qhov hnav tab sis kuj txo qhov tsis kam ntawm cov kua dej, pab cov khoom siv kom siv hluav taws xob ntau dua.
Kev txhim kho cov silicon carbide wear-resistant blocks rau ntawm "cov ntsiab lus yooj yim hnav" ntawm cov khoom siv zoo li muab ib txheej ntawm "tsis pom kev armor" rau ntawm cov khoom siv. Qhov txiaj ntsig ncaj qha tshaj plaws yog ua kom lub neej ntawm cov khoom siv ntev dua, txo cov lej ntawm kev kaw thiab hloov pauv, thiab txo cov nqi txij nkawm; Qhov thib ob, ua kom ruaj khov cov txheej txheem ntau lawm kom tsis txhob muaj kev poob qis lossis cov khoom ua qias tuaj los ntawm kev hnav thiab tsim kua muag hauv zos; Tib lub sijhawm, vim nws cov duab thiab qhov loj me uas tuaj yeem hloov kho raws li qhov xwm txheej tiag tiag ntawm cov khoom siv, txoj kev teeb tsa kuj yooj ywm thiab ntau yam. Txawm hais tias nws tau kho nrog bolts lossis sib txuas nrog cov nplaum tshwj xeeb, nws tuaj yeem ua tiav qhov haum nruj, kom ntseeg tau tias nws tsis yooj yim poob tawm hauv qab kev puas tsuaj loj heev.
Tau kawg, txhawm rau kom lub thaiv uas tiv taus hnav ua haujlwm tau tiag tiag, kev xaiv thiab kev teeb tsa cov ntsiab lus tseem ceeb ib yam. Piv txwv li, hom thiab cov qauv tsim nyog ntawm silicon carbide yuav tsum tau xaiv raws li qhov loj me ntawm cov khoom me me, tus nqi ntws, qhov kub, thiab cov khoom siv tshuaj lom neeg ntawm cov khoom nruab nrab; Thaum lub sijhawm teeb tsa, xyuas kom meej tias qhov chaw huv si thiab lo rau kom tsis txhob muaj kev ntxhov siab los ntawm "kev ntaus hnyav"; Thaum siv, sim ua kom muaj kev ua haujlwm ruaj khov thiab zam kev ntws thiab kev hloov pauv ntawm cov concentration ntau dhau. Los ntawm kev ua cov no zoo, lub neej thiab kev ua haujlwm ntawm lub thaiv uas tiv taus hnav yuav lav ntau dua.
Zuag qhia tag nrho, cov blocks silicon carbide uas tiv taus kev hnav yog ib qho kev daws teeb meem "me me rau loj": lawv tsis loj, tab sis tuaj yeem tiv thaiv cov khoom siv tseem ceeb thiab tiv thaiv kev tsim khoom tas mus li. Yog tias koj kuj muaj teeb meem los ntawm cov teeb meem hnav hauv zos hauv kev tsim khoom, koj yuav xav kawm txog cov blocks silicon carbide uas tiv taus kev hnav thiab saib seb lawv tuaj yeem "txo qhov hnyav" ntawm koj cov khoom siv thiab "ntxiv cov ntsiab lus" rau koj lub peev xwm tsim khoom li cas.
