Khoom zoo
① Peroxide Curing - Thermal stability
Peroxide curing forms C-C crosslinks (~ 85 kcal / mol), muab cov thermal stability ntau dua li leej faj- kho tshuab.
Ntawm 150℃× 70h, compression teeb tuaj yeem ncav cuag tsawg dua lossis sib npaug li 16%, piv rau Ntau dua lossis sib npaug li 25% rau kev kho cov sulfur.
② Kub Kub Kev laus tiv taus
Kev khiav hauj lwm ntau yam: -40℃txog 150 degree, mus txog 160℃hauv roj xov xwm.
Tom qab 150℃× 70h laus (ASTM D865):
Hardness hloov tsawg dua los yog sib npaug rau +10
Tensile hloov Tsawg dua lossis sib npaug rau -25% (feem ntau poob qis)
Elongation hloov tsawg dua los yog sib npaug rau -30%
③ Tsawg Compression Teeb
150℃× 70h: Tsawg dua lossis sib npaug li 25%
150℃× 22h: Tsawg dua lossis sib npaug li 20%
160℃× 70h: Tsawg dua lossis sib npaug li 35%
④ Media Resistance
Tau tshaj H₂S{0}}muaj roj, cav roj additives, refrigerants (R134a/R1234yf), thiab dilute acids/alkalis, nrog ruaj khov ntim hloov kev ua tau zoo nyob rau hauv cov qauv roj xeem.
⑤ Mechanical Strength
Tensile zog Ntau dua los yog sib npaug rau 16 MPa, elongation Ntau dua los yog sib npaug li 250%, haum rau hydraulic systems txog li tsawg dua los yog sib npaug rau 10 MPa nrog extrusion kuj.
⑥ Kev Pabcuam Lub Neej
Hauv 150℃cov roj kub kub, kev pabcuam lub neej yog 1.5-2 × ntev dua li HNBR tus qauv, txo qhov hloov zaus.
