Hauv kev lag luam niaj hnub tsim, kev ua yeeb yam ntawm cov khoom ntim ncaj qha txiav txim siab qhov ruaj khov thiab kev nyab xeeb ntawm cov cuab yeej. Raws li qhov kub siab, muaj mob siab, thiab muaj zog corrosion ntau zuj zus ua cov khoom siv roj hmab ntau, cov khoom siv roj hmab tsoos tsis txaus. Raws li yav tom ntej -} cov khoom siv roj hmab silicate, thiab huab cua sov, tau dhau los ua qhov kev xaiv zoo tshaj plaws hauv thaj teb ntawm kev lag luam sealing.
1. Cov tub ntxhais zoo ntawm cov khoom siv roj hmab silicone
Silicone roj hmab ntawv yog ib qho khoom loj ua los ntawm cov organic silicai polymers los ntawm precision tov thiab vulcanization. Piv nrog tsoos roj hmab, cov roj hmab silicone cov ntaub ntawv silicone tuaj yeem ua kom muaj kev kawm elicium thiab kev sib khi ua haujlwm nyob rau hauv kev kub ntxhov, deformation, lossis tawg. Nws ua hauj lwm kub ntau zaus feem ntau txuas ntawm-qib℃rau +250 degree, ua kom muaj kev txhim khu kev qha ntawv txawm tias nyob rau hauv cov kev hloov pauv kub heev.
Tsis tas li ntawd, cov roj hmab silicone cov ntaub qhwv muaj cov xim zoo tshaj plaws, UV tsis kam, thiab rwb thaiv hluav taws xob hauv hluav taws xob. Nws yog dav siv hauv tshuaj, hluav taws xob, kho tsheb, kev kho mob, thiab kev lag luam txhua yam. Txawm hais tias siv raws li lub siab {2} h siab} rwb thaiv tsev txheej, lossis cov hluav taws xob}} roj hmab roj hmab daim ntawv qhia ruaj khov thiab ntev} {} {}}}}}}}}}}}}} kav ntev.
2. Daim ntawv thov cov xwm txheej hauv kev lag luam sealing
Hauv teb ntawm kev lag luam sealing, cov roj hmab silicone roj hmab ntawv ua lub luag haujlwm tseem ceeb hauv ntau daim ntawv thov. Nws elasticity thiab yooj yim tshuab ua nws cov khoom zoo rau gaskets, rwb thaiv tsev cov ntaub, thiab txheej sib khi. Piv txwv li, hauv cov khoom siv tshuaj lom neeg, silicone roj hmab cov ntawv yooj yim tiv thaiv kom tsis txhob muaj cov xov xwm corrosive; Hauv cov tshuab hluav taws xob, lawv muab cov rwb thaiv tsev txhim khu kev qha thiab tiv thaiv tiv thaiv arc paug.
Cov ntaub qhwv cov roj hmab silicone tuaj yeem ua kom haum nrog du, matte, ntaub {{0} Cov qauv sib txawv, lossis cov chaw muaj kev sib txawv. Qee hom kev txhawb zog kuj tseem muaj cov fiberglass lossis hlau cov txheej txheem los txhim kho cov kua muag tsis kam thiab sab ruaj khov. Qhov no hloov kho tau muab cov roj hmab silicone
3. Kev sib piv nrog cov ntaub ntawv ib txwm muaj
Piv nrog cov ntxaij xws li nitrile lossis fluororubber, cov roj hmab silicone Txawm tias tom qab ntev- Todle raug rau kev kub siab, silicone roj hmab ntawv tseem nyob muag muag thiab dav. Tsis tas li ntawd, cov ntawv roj hmab silicone silicium yog cov inert, ua rau nws tiv taus cov kua qaub, alkalis, txuas ntxiv txuas nws cov kev pabcuam lub neej thiab txo cov nqi kho mob.
Los ntawm ib puag ncig lub tswv yim, cov roj hmab silicone
4. Yav Tom Ntej Kev Loj Hlob
Nrog rau kev txhim kho kev nyab xeeb ntawm kev muaj tshuab thiab kev ntse ntse tsim, kev ntseeg tau ntawm cov ntaub ntawv sealing tau dhau los ua kev cuam tshuam. Cov khoom siv roj hmab silicone
Kev tsim kho yav tom ntej yuav suav nrog:
Thermally ua raws silicone cov ntaub ntawv roj hmab rau hluav taws xob txias tshuab;
Hluav taws xob coj ua silicate roj hmab ntawv rau anti - zoo li qub thiab EMI Tiv Thaiv Kev Siv;
Siv cov roj hmab silicone roj hmab sib txuas ua ke nrog cov fibers, cov hlau, lossis ceramics rau kev txhim kho kev siv zog thiab seem ruaj khov.
Cov kev hloov tshiab no yuav txuas ntxiv rau daim ntawv thov Silicone cov ntaub ntawv roj hmab hauv Aerospace, cov khoom lag luam semiconductor, thiab lub zog khoom tshiab.
5. Xaus
Hauv cov ntsiab lus, cov ntaub ntawv roj hmab silicone tau dhau los ua cov khoom siv tsis tau hauv cov khoom siv sealing ua tsaug rau nws cov khoom siv lub cev thiab cov khoom yoog tau zoo. Nws txhim kho cov cuab yeej siv tau thiab kev nyab xeeb thaum txo cov nqi txij nkawm thiab lub neej pabcuam txuas ntxiv. Raws li thev naus laus zis txuas ntxiv hloov zuj zus, silicone roj hmab los xij yuav tsum tau xa cov nqi ntau dua thoob plaws ntau yam kev lag luam.
Yog tias koj lub tuam txhab nrhiav cov khoom sib khi uas muaj kev cuam tshuam nrog tshav kub, xeb, thiab kev laus, cov roj hmab silicone ntxeem tau.
