Tsawg qis qhov kub thiab txias ua kom zoo antylene prantylene prantenene epdm

Tsawg cov cua sov yooj yim, cov khoom siv hluav taws xob zoo, cov roj

hmab uas muaj kev sib txawv, ib puag ncig kev

ua phooj ywg, thiab kev ruaj khov ib puag ncig, thiab kev ruaj khov ib puag ncig, thiab kev ruaj khov ib puag ncig? Saib tsis muaj ntxiv tshaj li Ter 4047 ethylene prest areber teb roj hmab. Cov roj hmab ntau zaus ua ke tag nrho cov nta tshwj xeeb no kom xa cov kev ua tau zoo hauv ntau cov ntawv thov.

    Tsis tshua muaj ntsuas kub hloov

4047 qhov tsawg tshaj plaws hloov tau yog tsis muaj lwm yam kev xaiv, ua rau nws xaiv zoo rau cov ntawv thov hauv ib puag ncig txias. Nws cov cim tshwj xeeb tso cai rau nws tswj hwm nws cov khoom elastic txawm tias tsis tshua muaj kev ua tau zoo hauv qhov kub uas muaj qhov kub qis li -60 ° C. Qhov no ua rau nws xaiv zoo rau kev siv sab nraum zoov hauv cov huab cua txias lossis siv hauv cryogenic tshuab.

    Kev siv tau ua tiav

tiav 4047 txoj kev ua tiav zoo ua rau nws yooj yim rau kev tsim cov txheej txheem roj hmab siv ntau yam. Nws tuaj yeem yooj yim sib xyaw thiab moulded rau hauv cov duab nyuaj uas siv cov khoom siv roj hmab siv roj hmab. Cov roj hmab cov khoom siv lub cev zoo nkauj kuj tseem ua tau kev ua tau zoo sib xws, muab cov chaw tsim khoom lag luam nrog kev ntseeg tau thiab rov ua dua rau cov khoom ntim siab.

    Tshwj xeeb cov khoom siv

ter 4047 tsis tsuas muaj cov ntsuas kub tsawg thiab cov txheej txheem zoo tab sis kuj tseem khav theeb lub tswv ntawm cov khoom tshwj xeeb. Nws nruab nrab moey viscosity ua rau nws yooj yim los tuav thiab txheej txheem thaum nws cov ntsiab lus ethylene tsis zoo ua kom zoo cov khoom siv zoo. Nws ib puag ncig cov phooj ywg ua rau nws xaiv kom ruaj khov, thiab nws txoj kev ruaj khov zoo kom muaj kev ua tau zoo thiab rov ua dua. Nws tseem muab lub suab tshwj xeeb suab thiab kev tawm tsam los ntawm kev coj los ntawm kev sib cav, ua rau nws muaj kev xaiv zoo heev rau ntau cov ntawv thov.

Hauv kev xaus, Ter 4047 ethylene propylene roj hmab yog ib qho tshwj xeeb thiab ntau yam khoom siv uas muaj kev ua tau zoo hauv ntau cov ntawv thov. Nws qhov kev kub kub tsawg, cov txheej txheem zoo, nruab nrab mooney viscosity, ib puag ncig nrhiav kev daws teeb meem rau lawv cov teeb meem nyuaj tshaj plaws nrog roj hmab thev naus laus zis.
