Litšobotsi tse ka sehloohong tsa motsoako oa ho atolosa rabara oa EPDM

1. Ho hanyetsa botsofali:Motsoako oa rabara oa EPDMe na le khanyetso e ntle ea boemo ba leholimo, ho hanyetsa ozone, ho hanyetsa mocheso, acid le alkali resistance, ho hanyetsa mouoane oa metsi, botsitso ba mebala, ts'ebetso ea motlakase, ho tlatsa oli le mocheso oa mocheso oa kamoreng.

2. Ho hanyetsa mocheso o phahameng: motsoako oa rabara oa EPDM o ka sebelisoa nako e telele ho 120 ℃, 'me o ka sebelisoa ka nakoana kapa ka nakoana ho 150 - 200 ℃. E na le khanyetso e ntle ea mouoane oa metsi 'me ho hakanngoa hore e phahametse mocheso oa eona.

3. Ho hanyetsa kutu: ka lebaka la ho haella ha polarity le ho fokotseha ho tlaase ha rabara ea ethylene propylene ka manonyeletso a rabara a EPDM, e na le khanyetso e ntle ho lik'hemik'hale tse sa tšoaneng tsa polar tse kang joala, acid, alkali, oxidant, refrigerant, detergent, oli ea liphoofolo le meroho, ketone le mafura.

4. Elasticity e ntle: Lenonyeletso la rabara la EPDM le reketla ho feta motsoako oa rabara oa tlhaho.

Khokahano e bonolo ea rabara ea EPDM e ka fihla ho 150h ntle le ho robeha tlas'a maemo a 50 pphm ozone le 30% ho otlolla, ka ho hanyetsa boemo ba leholimo (sebelisa mocheso oa mocheso - 40 ℃ - 150 ℃) le khanyetso ea lik'hemik'hale. Ka mor'a hore e kenye ntho e thibelang malakabe, e na le ho lieha ho hoholo ha lelakabe le ho thibela lelakabe. Sehlahisoa se sebetsoa ke vulcanization ea microwave e tsoelang pele hang, e nang le bokaholimo bo boreleli le bo botle, ts'ebetso e tsitsitseng haholoanyane (mme ha ho bonolo ho e fetola.
