I-EPDM (E-Ithone proplene Diene Monomer) Irabha
Irabha ye-EPDMyi-copolymer ye-Ethylene, proplenene kunye nenani elincinci le-monomer yesithathu engakhange igcinwe. Igama lehlabathi li: I-Etheyone Proppeene Diene Methyiene, okanye i-EPDM yefutshane. Irabha ye-EPDM ilungeleUkuchasana ne-UV, ukumelana kwemozulu, ukuxhathisa ubushushu, ukunganyangeki kobushushu obuphantsi, ukunganyangeki kwe-ozone, ukuxhathisa kwamachiza, ukuxhaswa kwamanzi kunye ne-elaistity, nezinye iipropathi zomzimba kunye noomatshini. Ezi zibonelelo azinakutshintshwa ziinjongo ezininzi.
1. Ukuxhathisa kwemozuluNgaba amandla okubanda kakhulu, ubushushu, ukomisa kunye nokufuma ixesha elide, kwaye kuxhathisa ukumelana nekhephu kunye ne-windows kunye neendonga zekhephu.
2. Ukuxhathisa ubushushu bokwaluphala kuthetha ukuba kuyachasana nokomelela kwi-air humes eshushu. Ingasetyenziswa ngo-50 ~ 120 ℃ ixesha elide. Ingagcina iimpawu ezifanelekileyo ixesha elide kwi-140 ~ 150 ℃. Inokukhusela amaqondo obushushu aphezulu angama-230 ~ 260 ℃ ngexesha elifutshane. Ingadlala indima kwiShishini leziBonakalayo ezidolophini. Ukulibazisa ukusebenza; Ukudityaniswa nokusetyenziswa kwefomula ekhethekileyo,Irabha ye-EPDMInovelwano olufanayo ukusuka -50 ° C ukuya kwi-15 ° C. Olu kufakelo lwemveliso lwenze iziphumo eziphezulu zokusebenza.
3. KubaI-EPDMUnenkcaso egqwesileyo ye-ozone, ikwabizwa ngokuba "yirabha enkulu". Isetyenziswe ngokukodwa kwizakhiwo ezahlukeneyo zedolophu kunye nezalathiso zahlukeneyo zemomospheric kwaye zivezwe ngokupheleleyo emoyeni. Iya kubonisa imveliso yawo imveliso.
4. Ukuxhathisa kwi-radiation ye-ultraviolet ibonelela ngokhuseleko lwendalo kubasebenzisi bezakhiwo ezinyukayo; Inokumelana ne-60 ukuya kwi-150kv voltage, kwaye ichaze kakhulu i-corona, ukunganyangeki kombane, kunye nokuxhathisa i-ArC. Iqondo lokushisa eliphantsi eliphantsi, iqondo lobushushu xa amandla e-subile efikelela i-100MPA ngu -58.8 ℃.
5. Ngenxa yeepropathi zayo ezilungileyo zezomatshini, ihlala isetyenziswa ekwenzeni inqwelo moya, iimoto, iibhasi ze-windows, ii-voltage eziphezulu, ii-voltal eziphezulu, ii-tunnels, ii-tunnels, iinxalenye ze-viaduct kunye nezinye iindawo zokutywina kwamanzi kunye nezinye izinto zokutywina kwamanzi kunye nezinye izinto zokutywina kwamanzi kunye nezinye izinto zokutywina kwamanzi kunye nezolimo.

I-Silicon (irabha ye-silicone)
1. Ngenxa yeengenelo zeempawu zezakhiwo zeirabha ye-silicone, kunokubanakho ukugcina uzinzo oluhle ngaphakathi kwexesha elithile kunye nodidi lwamaqondo obushushu. Xa kuthelekiswa nolunye uhlobo lwe-synthert, irabha ye-silicone inokumelana nobushushu obu-51 ukuya kwi-316 ° C kwaye igcine iipropathi zayo.
I-2. Ezinye iipropathi ezizodwa zalo mgama jikelele:Ukunganyangeki kwe-radiation, ifuthe elincinci ledosi yokubulala iintsholongwane; Ukunganyangeki kwentshukumo, phantse ireyithi yothungelwano eqhubekayo kunye nezakhiwo zokuphumla nge-50 ~ 65 ° C; Ukuphefumla okungcono kunezinye ii-polymers zepropathi; Isidima samandla 500v · ne-1; Inqanaba lokuhambisa <0.1-15ωm; ukhulule okanye ugcine amathembumba; Ubushushu obungasebenziyo 4982 ° C; ubuncinci bokukhula emva kokudityaniswa okufanelekileyo; ilungele ukusetyenziswa kwesicelo phantsi kwemigaqo yolawulo lokutya ukugcwaliswa kokutya; iipropathi ezihlawulayo; Iimveliso ezingenamibala kunye ne-odols zinokuveliswa; Iipropathi zamanzi; I-intergeogical dieternity yezityholo ezintlanu kunye neendawo zokuziphatha zonyango.
