High mechanical zog. Petroleum resin muaj zog cohesion thiab ntom molecular qauv, Petroleum Resin yog li nws cov khoom siv kho mob siab dua li cov hom phiaj thermosetting resins xws li phenolic resin thiab unsaturated polyester. Kev sib txuas ua haujlwm zoo heev.
Txawm hais tias roj av resins tau muab faib ua plaub hom, Petroleum Resin txoj kev tsim khoom yog tib yam. Tsuas yog qee qhov DCPD resins ua los ntawm thermal polymerization, Petroleum Resin tus so yog siv los ntawm cationic polymerization. Cov catalysts muaj qee zaum ntxiv nrog me ntsis accelerator.
Beige C9 roj av resin tsis zoo-zoo, tab sis nws yog cov khoom nplooj ntsuab, Petroleum Resin ntsiag to, tab sis nws plays lub hom phiaj zoo heev. Tsis zoo li qee cov neeg nrov nrov uas nyiam caw kom muaj txiaj ntsig, Petroleum Resin C9 roj av resin yog siv rau hauv cov kua nplaum Hauv cov khoom siv tshuaj lom neeg thiab cov khoom siv kho kom zoo nkauj, cov ntsiab lus yuav tsum tau them sai sai rau thaum yuav, Petroleum Resin yam C9 roj av resin yog qhov zoo tshaj plaws. ? Dab tsi yog qhov zoo?
Petroleum resin yog ib hom thermoplastic resin uas ua los ntawm kev tawg C5 olefins hauv cov khoom ntawm ethylene cog los ntawm pretreatment, polymerization, Petroleum Resin flash evaporation thiab lwm yam txheej txheem. Nws yog ib qho oligomer nrog cov txheeb ze molecular loj li ntawm 300 txog 3000. Roj av resin muaj insoluble hauv dej, Roj av Resin yooj yim soluble nyob rau hauv organic solvents, Roj av Resin acid kuj, alkali tsis kam, dej tsis kam, Roj av Resin tshuaj tiv thaiv, roj av Resin. kev laus thiab lwm yam khoom zoo heev.
Petroleum resin chemical element qauv qauv: Petroleum resin ntau lawm daim ntaub ntawv yog C9 roj av resin thiab C5 roj av resin.C5 roj av resin yog yus muaj los ntawm nws siab tev adhesion zog, Roj av Resin zoo ceev adhesion, Petroleum Resin ruaj khov adhesion kev ua tau zoo, nruab nrab yaj zoo viscosity kuj, zoo compatibility nrog siab polymer matrix, Petroleum Resin thiab tus nqi qis. Resin tackifier (rosin thiab terpene resin).
C5 roj av resin tseem hu ua C5 roj av resin, Petroleum Resin uas tau tuav txoj haujlwm tseem ceeb ua cov tackifying resin. Ntawm lawv, Petroleum Resin feem ntau siv yog cov nplaum nplaum kub thiab cov nplaum nplaum nplaum, Roj Hmab Resin roj hmab log tsheb thiab lwm yam. Petroleum resins yog tsim rau kub-melt adhesives, siab-rhiab nplaum nplaum thiab roj hmab log tsheb.
