Hauv kev lag luam niaj hnub no, feem ntau cov kev lag luam muaj qhov chaw ua haujlwm kub. Ntau lub tshuab loj ua haujlwm tib lub sijhawm ntev, uas yuav tsim kom muaj cua sov ntau. Los ntawm aerospace mus rau lub zog teb, los ntawm kev tsim tsheb mus rau cov txheej txheem tshuaj, lub hav zoov ntawm qhov kub thiab txias ib puag ncig yog qhov kev sim hnyav rau seb cov khoom siv thiab cov tshuab tuaj yeem tswj hwm lawv qhov kev ua tau zoo li cas. Tawm tsam keeb kwm yav dhau los no, ntau yam roj hmab ntsaws ruaj ruaj hauv cov khoom siv kuj yuav tsum muaj peev xwm tiv nrog qhov kev sim no. Lub high-temperature-resistant series ntawm roj hmab foob tuaj yeem muab kev daws teeb meem rau ntau yam kev lag luam.
Vim li cas thiaj siv cov roj hmab uas muaj qhov kub thiab txias
Raws li qhov tseem ceeb ntawm cov khoom sib khi, cov roj hmab foob ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov kua dej, gases, thiab impurities. Txawm li cas los xij, cov khoom siv roj hmab tsoos feem ntau ua haujlwm tsis zoo nyob rau hauv qhov kub thiab txias thiab ua rau poob ntawm elasticity, hardening, los yog brittleness. Txhawm rau ua kom tau raws li qhov xav tau ntawm kev sib khi ua haujlwm nyob rau hauv qhov chaw kub kub, peb tau tsim cov roj hmab cov ntsaws ruaj ruaj tshiab thiab tsim cov khoom kub-resistant.
Cov ntaub ntawv tshwj xeeb thiab cov txheej txheem
Tshiab-kub-resistant roj hmab seals siv cov khoom siv roj hmab tshwj xeeb thiab cov txheej txheem los tiv thaiv qhov kub thiab txias. Ua ntej, cov khoom siv roj hmab uas muaj kev ruaj ntseg zoo tau raug xaiv, xws li roj hmab fluorine (FKM) lossis silicone roj hmab (VMQ). Cov ntaub ntawv no lawv tus kheej muaj kev kub ntxhov thiab tshuaj lom neeg. Ntxiv mus, cov txheej txheem tshwj xeeb xws li kev kho cua sov thiab txheej txheej yog siv los txhim kho qhov kub-kub tsis kam ntawm cov roj hmab foob. Daim ntawv thov ntawm cov thev naus laus zis no tso cai rau cov roj hmab ntsaws ruaj ruaj kom muaj qhov zoo elasticity thiab sealing kev ua tau zoo nyob rau hauv qhov kub thiab txias ib puag ncig, ua kom muaj kev ua haujlwm zoo ntawm cov khoom siv thiab cov tshuab.
Daim ntawv thov Scope
High-temperature-resistant roj hmab seals muaj ntau yam kev siv. Hauv thaj chaw aerospace, lawv tau siv los kaw cov cuab yeej kub kub xws li lub cav thiab cov roj turbines kom ntseeg tau tias cov roj thiab cov roj lubricating tsis txhob xau thaum tiv thaiv cov impurities sab nraud nkag mus. Hauv kev lag luam hluav taws xob, cov khoom siv hluav taws xob tiv thaiv kev kub ntxhov yog siv rau hauv cov txheej txheem kub xws li nuclear fais fab nroj tsuag, thee-fired fais fab nroj tsuag, thiab petrochemical cov cuab yeej los xyuas kom meej kev ruaj ntseg thiab txhim khu kev qha kev khiav hauj lwm ntawm lub system. Hauv kev lag luam tsheb tsim khoom, cov ntsaws ruaj ruaj uas muaj qhov kub thiab txias yog siv rau hauv cov cav tov, cov tshuab tso pa, hydraulic systems, thiab lwm qhov chaw los tiv thaiv cov teeb meem ntawm qhov kub thiab txias.
Lwm qhov zoo
Ntxiv nrog rau qhov kub thiab txias tsis kam, cov roj hmab tshiab no muaj lwm yam khoom zoo heev. Lawv kuj muaj cov pa roj tsawg thiab cov kua permeability, zoo hnav tsis kam, thiab tuaj yeem hloov mus rau ntau qhov chaw ua haujlwm thiab ib puag ncig. Cov yam ntxwv no ua rau kub-resistant roj hmab seals nrov hauv ntau qhov kev lag luam.
Customized xav tau
Raws li kev siv thev naus laus zis txuas ntxiv mus thiab kev xav tau txuas ntxiv mus ntxiv, peb yuav txuas ntxiv ua haujlwm ntawm kev tsim cov khoom tsim tshiab thiab txhim khu kev qha siab kub. Qhov no yuav pab tau ntau yam kev lag luam kov yeej cov teeb meem tshwm sim los ntawm qhov kub thiab txias ib puag ncig thiab txhim kho cov cuab yeej kev ntseeg siab thiab kev ua haujlwm. Tsis tas li ntawd, nrog rau kev txhim kho sai ntawm lub zog tauj dua tshiab, cov cuab yeej siv hluav taws xob huv xws li cua turbines tseem yuav tso cov kev xav tau siab dua ntawm cov roj hmab uas muaj kub-resistant. Yog tias koj muaj lwm yam kev xav tau tshwj xeeb, thov koj xav tiv tauj peb. Peb cia siab tias peb tseem yuav muaj Lub Zog tuaj yeem ua tau raws li koj qhov yuav tsum tau ua.
Xaus
Nyob rau hauv luv luv, qhov yuav tsum tau tiv nrog huab ib puag ncig tau tsav lub nruam innovation thiab kev loj hlob ntawm roj hmab seals. Kev lag luam kub-resistant roj hmab foob kev lag luam muab cov kev daws teeb meem zoo rau ntau yam kev lag luam kom ntseeg tau tias kev lag luam txhim khu kev qha ntawm cov kab ke hauv qhov chaw kub kub. Nyob rau hauv lub neej yav tom ntej, nrog rau kev txhim kho ntxiv hauv kev siv thev naus laus zis thiab kev xav tau ntau ntxiv, peb tuaj yeem cia siab tias cov khoom siv roj hmab uas muaj qhov kub thiab txias los ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam thiab pab txhawb kev txhim kho thiab kev ruaj khov ntawm kev lag luam.
