Raws li tus xa khoom ntawm hluav taws ntsaws cov hluav taws kub EPDM ntsaws ruaj ruaj, Kuv feem ntau ntsib cov lus nug txog kev sib tw shear ntawm cov tseem ceeb ntawm cov tseem ceeb. Nkag siab txog lub zog ntawm hluav taws xob ntawm hluav taws kub yog qhov tseem ceeb rau kev ua kom tau nws cov kev ua tau zoo hauv ntau yam kev siv, tshwj xeeb hauv hluav taws- kev nyab xeeb kev nyab xeeb.
Cov hauv paus ntawm shear lub zog
Lub zog shear yog hais txog qhov ntau ntawm shear kev nyuaj siab tias cov khoom tuaj yeem tiv taus ua ntej nws ua tsis tiav. Nyob rau hauv cov ntaub ntawv hluav taws kub epdm (ethylene {{1} {{{{{2} {{2}- Monomer {}} Monomer, ua rau ib feem ntawm cov ntaub ntawv rau lwm tus. Qhov no tuaj yeem tshwm sim vim muaj ntau yam xws li kev txav hauv cov qauv uas lub foob nyob qhov twg lub foob nyob sab nraud thiab kev cog lus, lossis cov rog sab nraud.
Yam cuam tshuam rau cov shear lub zog ntawm cov hluav taws rated EPDM ntsaws ruaj ruaj
Cov Khoom Siv Cov Khoom Siv
Qhov muaj pes tsawg leeg ntawm EPDM roj hmab yog ib qho tseem ceeb ua feem cuam tshuam shear lub zog. Siab -} Zoo} Cov tebchaw zoo epdm siv hauv hluav taws rated ntsaws nrog kev sib ntxiv tshwj xeeb thiab cov polymers. Cov khoom ntxiv no txhim kho cov cuab yeej siv ntawm cov roj hmab, suav nrog nws cov shear tsis kam. Piv txwv li, qhov kev sib ntxiv ntawm kev txhawb nqa cov chav ua haujlwm tuaj yeem txhawb cov qauv sab hauv kev ncaj ncees, tso cai rau lub foob rau kev tiv thaiv shear zoo dua.
Hla -} kev txuas ceev ntom ntom ntom ntom
Hla -} kev sib txuas yog cov txheej txheem tshuaj lom neeg uas khi cov saw hlau polymer hauv cov roj hmab EPDM ua ke. Ib qho siab dua hla - ntawv txuas feem ntau tshwm sim hauv cov khoom muaj zog thiab ntau dua. Nyob rau hauv hluav taws rated EPDM ntsaws ruaj ruaj, ib qho zoo tshaj plaws hla {{}}} Txuas ntom ntom ntom ntom ntom. Yog tias tus ntoo khaub lig-} Txuas yog tsawg dhau, lub foob yuav dhau mus muag thiab ntxim nyiam rau shear tsis ua haujlwm. Ntawm qhov tod tes, ntau hla hla {8} Kev sib txuas tau tuaj yeem ua rau lub peev xwm sib txawv, uas tuaj yeem ua rau thaum ntxov ua tsis tau raws li kev ntxhov siab sheats.
Qho so
Qhov kub muaj qhov cuam tshuam tseem ceeb ntawm cov hluav taws xob ntawm hluav taws kub ntawm hluav taws xob kaw. Thaum ib puag ncig cua sov, EPDM roj hmab muaj qee theem ntawm kev yoog raws thiab shear tsis kam. Txawm li cas los xij, raws li qhov kub kub nce, tshwj xeeb tshaj yog nyob rau qhov teeb meem hluav taws, lub zog ntawm lub cev ntawm cov roj hmab hloov. EPDM tuaj yeem pib ua kom mos muag ntawm qhov kub thiab txias, txo nws lub zog shear. Hluav taws kub hluav taws xob EPDM ntsaws ruaj ruaj yog tsim los tswj kom muaj qee qib kev ncaj ncees thiab kev ua tau zoo txawm nyob ntawm ntug dej kub. Tshwj xeeb hluav taws - tiv taus rau cov txheej txheem degradation thiab pab lub foob khaws nws lub zog txav rau ib lub sijhawm thaum hluav taws.
Cov xwm txheej
Kev teeb tsa yog qhov tseem ceeb rau kev cia siab tias lub zog shear zog ntawm hluav taws kub EPDM foob. Yog hais tias lub foob tsis tau nruab kom raug, nws yuav raug rau kev faib tsis tau kev ntxhov siab. Piv txwv li, yog hais tias lub foob yog ncab lossis compressed ntau dhau thaum lub sij hawm teeb tsa, nws tuaj yeem tsim cov ntsiab lus tsis muaj zog uas muaj feem ntau yuav tsis muaj kev sib tw poob qis. Ib qho ntxiv, qhov chaw uas cov foob uas cov foob nyob qhov twg yog ntsia yuav tsum yog huv, uas yog qhov tseem ceeb kom tswj cov shear tiv thaiv.
Ntsuas lub zog shear ntawm hluav taws kub EPDM ntsaws ruaj ruaj
Muaj ob peb txoj kev ntsuam xyuas cov qauv los ntsuas cov khib nyiab ntawm EPDM ntsaws ruaj ruaj. Ib txoj kev ib txwm yog ASTM D732 xeem, uas muaj feem cuam tshuam nrog lub zog shear rau ib qho quav ntawm cov khoom sib tsoo kom txog thaum nws swb. Qhov siab tshaj plaws shear kev ntxhov siab ntawm qhov tsis ua tiav tau sau tseg raws li lub zog shear. Lwm qhov kev sim cuam tshuam yog ISO 815 tus qauv, uas ntsuas cov khoom siv compression teeb thiab shear cov khoom ntawm cov khoom siv roj hmab raws li cov xwm txheej sib txawv. Cov kev ntsuam xyuas no yog qhov tseem ceeb heev rau kom ntseeg tau tias cov ntsaws ruaj ruaj EPDM ntsaws ruaj ruaj raws li cov qauv kev lag luam thiab kev ua tau zoo.
Cov ntawv thov thiab qhov tseem ceeb ntawm Shear lub zog
Hluav taws kub -} tiv taus qhov rai thiab qhov rooj
Hauv hluav taws -} Cov qhov rooj resistant qhov rai thiab qhov hluav taws xob, hluav taws kub ntaus lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev kis hluav taws thiab pa taws. Cov ntsaws ruaj ruaj yuav tsum tau tiv thaiv lub zog tsim los ntawm kev nthuav dav thiab kev txhawb nqa ntawm lub qhov rais lossis lub qhov rooj ntas thaum hluav taws. Lub zog shear zog ua kom muaj txiaj ntsig uas cov foob tseem muaj txiaj ntsig zoo thiab muab cov gaps zoo rau cov nplaim taws thiab cov roj kub.
