C9 roj av resin yog ib qho thermoplastic cob uas ua los ntawm kev tawg cov khoom los ntawm C9 feem ntawm ethylene ntau lawm chav tsev ua cov khoom siv tseem ceeb, Petroleum Resin polymerizing nws nyob rau hauv lub xub ntiag ntawm ib tug catalyst, Petroleum Resin los yog copolymerizing nws nrog aldehydes, aromatic hydrocarbons, terpenes. Nws cov molecular loj yog feem ntau tsawg dua 2000, Petroleum Resin softening point yog tsawg dua 150 âº, Petroleum Resin nws yog ib qho thermoplastic viscous kua lossis khoom.
Petroleum resin yog lub npe vim nws yog muab los ntawm roj av derivatives. Nws muaj cov yam ntxwv ntawm tus nqi qis, Roj av Resin zoo miscibility, dej tsis kam, Roj av Resin ethanol tsis kam thiab tshuaj lom neeg. Nws yog tshuaj lom neeg ruaj khov rau cov kua qaub thiab cov hauv paus thiab muaj viscosity zoo thiab thermal stability. Nta. Petroleum resins feem ntau tsis yog siv ib leeg xwb, Petroleum Resin tab sis raws li accelerators, regulators, modifiers thiab lwm yam resins.
Lub cev muaj zog: Petroleum resins tsim siv C9 feem hauv roj av raws li cov khoom siv raw hu ua C9 roj av resins. Nws yog tau los ntawm polymerizing cov seem seem (C8 ~ C11) tom qab sib cais benzene, Petroleum Resin toluene thiab xylene los ntawm hnyav los ntawm cov khoom tawg cov roj. Nyob rau hauv chav tsev kub, nws yog ib tug iav thermoplastic khoom, nkig, Roj av Resin lub teeb daj mus rau lub teeb xim av, nruab nrab molecular luj 500 ~ 1000.
Cov khoom tsim kev puas tsuaj uas tsim los ntawm kev sib tsoo ntawm cov roj av: cov pa taws, pos huab, Petroleum Resin carbon oxides, cov khoom tawg tsis tiav, Petroleum Resin thiab flammable hydrocarbons. Cov hluav taws tua hluav taws yuav tsum siv cov cuab yeej tua hluav taws uas tsim nyog: siv cov dej pos huab, ua npuas dej, Roj av Resin qhuav hmoov lossis carbon dioxide tua hluav taws.
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.
