Hav muaj! Raws li tus neeg xa khoom ntawm EPDM sib khi cov strips, Kuv feem ntau tau nug txog kev tawv ntawm cov khoom lag luam. Yog li, cia tus khawb rau hauv qhov nyuaj ntawm EPDM sib khi cov kab txaij tiag tiag txhais tau tias thiab vim li cas nws tseem ceeb.
Thawj zaug tawm, dab tsi epdm? EPDM sawv rau ethylene propylene diene mones. Nws yog hom hluavtaws hluavtaws hluavtaws uas paub txog nws cov huab cua zoo heev, ozone kuj, thiab rawv hluav taws xob cov khoom lag luam. Cov nta no ua rau epdm sealing strips super nrov nyob rau hauv ib pawg ntawm kev lag luam, los ntawm kev lag luam los tsim kho.
Tam sim no, cia peb tham txog Hardness. Lub hardness ntawm Epdm Sealing ib daim hlab feem ntau yog ntsuas siv lub Ntug Dej Dureter Start. Muaj ntau hom kev sib txawv ntawm ntug dej hiav txwv, tab sis rau epdm, peb feem ntau siv ntug dej hiav txwv. Qhov ntsuas no yog los ntawm 0 txog 100, uas tus lej qis txhais tau tias cov khoom yog softer, thiab tus lej siab dua txhais tau tias nws nyuaj dua.
Mos EPDM Sealing strips, hais nrog ntug dej ib lub hardness ntawm ib ncig 30 - 40, yog hloov tau. Lawv tuaj yeem yooj yim yoog raws qhov chaw tsis xwm yeem, uas ua rau lawv zoo rau cov ntawv thov uas xav tau ntawm thaj chaw tsis sib xws. Piv txwv li, hauv qee cov ntawv thov Automotive, zoo li cov huab cua EPDM tuaj yeem tsoo cov qhov rooj thiab lub qhov rais epdm tuaj yeem ua rau dej zoo li, ua kom dej tawm, hmoov av. Qhov kev sib xyaw ntxiv kuj tseem tso cai rau kev teeb tsa yooj yim, vim tias lawv tuaj yeem khoov duav thiab puab yam tsis muaj tawg.
Ntawm qhov tod tes, harder EPDM sealing strips nrog ntug dej nyab ntawm 70 - 90 yog ntau nruj. Lawv muab qhov zoo dua tsis kam mus rau compression thiab deformation. Hauv chaw muaj kev muaj, qhov chaw muaj kev kub siab lossis hnyav, nyuaj EPDM ib daim hlab yog feem ntau mus -} los xaiv. Piv txwv li, nyob rau hauv cov tshuab nyob qhov twg muaj qhov chaw txav mus los saib xyuas nws cov kab mob tshwm sim hauv siab, ib qho nyuaj EPDM sawb tuaj yeem ua txoj haujlwm zoo.
Tab sis vim li cas hardness teeb meem ntau heev? Zoo, nws cuam tshuam ncaj qha cuam tshuam kev ua yeeb yam ntawm cov sealing sawb. Yog tias koj xaiv Sawb uas yog dhauft rau lub siab -} hillaging app, nws yuav tau compressed ntau thiab poob nws lub peev xwm sib luag nyob rau lub sijhawm. Ntawm Flip sab, yog tias koj siv lub zog tawv uas yooj yim yog qhov yuav tsum tau, nws yuav tsis tsim ib qho kev txiav tawm kom zoo, tawm hauv cov khoom tsis xav tau.
Cia peb saib ntawm qee cov kev siv thiab qhov zoo tshaj plaws rau txhua tus.
Kev Lag Luam Automotive
Nyob rau hauv cov tsheb, ntau qhov chaw yuav tsum sib txawv qib ntawm epdm sealing strips. Raws li kuv tau hais ua ntej lawm, rau kev ua kom sov siab dua, rau lub qhov rooj thiab lub qhov rais, ib qho softer sawb (ntug dej hiav txwv (ntug dej hiav txwv {1} {1} {1} { Nws tuaj yeem hloov kho cov duab ntawm lub qhov rooj thav duab thiab lub khob qhov rai, tsim ib lub khob dej nyab thiab airtight foob. Txawm li cas los xij, rau cov cav sib ceg, qhov muaj kev vibrations thiab qhov kub thiab txias dua, ib qho nyuaj (ntug dej nyuaj (ntug dej siab (ntug dej. Nws tuaj yeem tiv thaiv kev ntxhov siab thiab tswj nws cov duab zoo dua.
Kev Tsim Kho Kev Tsim Kho
Hauv kev tsim kho, EPDM sealing ib daim hlab yog siv rau ntau lub hom phiaj, xws li cov pob qij txha hauv cov vaj tse. Rau cov pob qij txha nthuav dav, ib qho softer sawb tuaj yeem ua kom muaj kev txav ntawm cov ntaub ntawv lub tsev vim qhov ntsuas kub. Ib tug ntug dej hardness ntawm 40 - 60 yog feem ntau xaiv qhov zoo ntawm no. Rau ntau li qub ntsaws ruaj ruaj, zoo li cov kav dej hauv av lossis hauv pre- sawb (ntug dej tawv (ntug dej siab.
Hluav Taws Xob Hluav Taws Xob
EPDM cov hluav taws xob rwb thaiv tsev zog ua nws cov khoom siv zoo rau kev lag luam hluav taws xob. Rau kev sib khi hluav taws xob ua haujlwm, ib txoj hlua khi nrog lub hardness nrab (ntug dej ib 50 - 70) yog feem ntau siv. Nws tuaj yeem muab cov nyiaj sib npaug zoo ntawm kev teeb tsa rau kev teeb tsa thiab nruj los tswj cov foob ntawm hmoov av thiab noo noo, uas yog cov yeeb ncuab ntawm cov hluav taws xob sib xyaw.
Tam sim no, thaum nws los txog rau kev tsim khoom lag luam, lub hardness ntawm epdm sealing strips tuaj yeem hloov kho los ntawm kev hloov cov khoom siv roj hmab. Ntxiv cov puv tsev lossis hloov tus ntoo khaub lig-} Txuas ntom ntom ntom ntom ntom, thaum siv cov tshuab yas ua tau cov sawb softer.
Peb tseem muab ntau hom EPDM sealing strips, zoo li co -} epdm gaskets thiab EPDM daim txhuam cev ua npuas roj hmab. Co - Cov gaskets tuaj yeem muaj cov qib nyuaj sib txawv hauv cov sawb, uas tso cai rau kev sib xyaw ua ke thiab kev sib xyaw ua ke hauv ib qho khoom. Qhov no yog qhov muaj txiaj ntsig tiag tiag hauv cov ntawv thov uas cov kev xav tau sib txawv yuav tsum tau ua tib lub sijhawm.
EPDM daim txhuam cev ua npuas roj hmab, ntawm qhov tod tes, feem ntau muaj qis dua thiab ib softer xav. Nws yog qhov zoo rau cov ntawv thov uas tau siv lub zog cushinged uas xav tau, xws li hauv qee cov neeg siv khoom lossis hauv qee hom rwb thaiv tsev.
Yog tias koj nyob hauv kev ua lag luam rau EPDM sealing strips, nws yog ib qho tseem ceeb kom txiav txim siab lub hardness raws li koj daim ntawv thov tshwj xeeb. Koj tsis xav mus xaus nrog ib lub sawb uas yog cov tawv muag dhau los lossis nyuaj dhau rau txoj haujlwm. Thiab qhov ntawd yog qhov chaw uas peb tuaj rau hauv. Raws li ib tug neeg xa khoom, peb muaj kev txawj ntse los pab koj xaiv qhov ncaj ncees thiab hom EPDM sib khi rau koj cov kev xav tau.
Txawm hais tias koj ua haujlwm ntawm qhov kev tsim kho tsheb, kev tsim kho cov khoom siv hluav taws xob, peb tuaj yeem muab koj nrog high - Zoo epdm sealding strips. Peb cov khoom raug sim kom ntseeg tau tias lawv ua tau raws li cov qauv uas yuav tsum muaj thiab ua tau zoo hauv kev ntseeg tiag tiag.
Yog li, yog tias koj xav paub txog kev kawm ntau dua lossis ua kev yuav khoom, tsis txhob ua siab deb mus txog. Peb nyob ntawm no los pab koj nrog tag nrho koj EPDM Sealing Sawb xav tau thiab pab koj nrhiav cov kev daws teeb meem zoo tshaj plaws rau koj qhov project.
