Cov tawg C9 feem ntau muaj cov tsis muaj ntxhiab tsw ntxhiab hydrocarbon tebchaw xws li vinyl toluene, indene, methylstyrene, Petroleum Resin thiab lwm yam.
Cov txheej txheem kev npaj ntawm C9 roj av resin yog raws li nram no: cov ntaub ntawv raw yog pretreated kom tshem tawm (bis) cyclopentadiene thiab isoprene, Roj av Resin kom tau raw cov ntaub ntawv nrog ib tug loj feem ntawm ntau tshaj 50%, Petroleum Resin thiab ces ntxiv ib tug diluent aromatic hydrocarbon. nyob rau hauv kev tiv thaiv ntawm nitrogen, Petroleum Resin Ces ntxiv cov catalyst AlCl3.
Txoj kev loj hlob ntawm C9 roj av resin ntau lawm nyob rau hauv tsev thiab txawv teb chaws: kev loj hlob ntawm petrochemical kev lag luam muab nplua nuj thiab pheej yig raw cov ntaub ntawv rau zus tau tej cov roj av resin, Petroleum Resin thiaj li zus tau tej cov roj av resin nyob rau hauv ib co petrochemical tsim lub teb chaws yog tsim sai heev.
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.
