Qhov zoo ntawm ethylene propyleneroj hmab sealing nplhaib
1. Kev laus zoo heev. Qhov zoo tshaj plaws ozone tsis kam, zoo dua li butyl roj hmab thiab CR. Zoo huab cua tsis kam, 3 xyoos nyob rau hauv lub hnub tsis muaj kab nrib pleb. NR150 hnub tawg, SBR5 hnub tawg, 70 hnub tawg. Zoo aging kuj. Nws tuaj yeem siv rau lub sijhawm ntev ntawm 150 degree. Kev laus kuj yog qhov zoo tshaj plaws universal roj hmab.
2, tshuaj tiv thaiv corrosion. Rau ntau hom tshuaj polar thiab acids, alkali muaj kev tiv thaiv ntau dua. Tsis zoo rau cov roj hydrocarbon.
3, zoo hluav taws xob rwb thaiv tsev. Ntau tshaj li roj hmab butyl, haum rau 45 ~ 65KW siab siab.
4. Kev cuam tshuam zoo thiab ua haujlwm txias. Tus nqi rov qab tuaj yeem ncav cuag 50 feem pua ~ 60 feem pua, thib ob nkaus xwbNR and BR. Lub elastic retention kev ua tau zoo dua ntawm qhov kub thiab txias, hardening ntawm -57 degree, brittle ntawm -77 degree .
Qhov tsis zoo ntawm ethylene propylene roj hmab sealing nplhaib: curing ceev yog qeeb
Peb mus rau plaub zaug qeeb dua li qub. Nyuaj hauv kev sib xyaw nrog lwm cov pos hniav unsaturated; Nws tus kheej viscosity thiab kev sib nrig sib viscosity tsis zoo, adhesion nyuaj, kev ua haujlwm tsis zoo. Tab sis nws yog ib qho yooj yim kom tau txais cov ntaub ntawv raw, pheej yig tus nqi, feem ntau yog siv hauv roj hmab hose, daim kab xev, nws pib qhov chaw, hlau thiab cable.
