Petroleum resin tuaj yeem siv dav hauv ntau lub lag luam, Roj av Resin xws li xim, roj hmab, thiab lwm yam. Vim li cas roj av resin thiaj li nrov?
Muaj ob txoj hauv kev tseem ceeb ntawm kev hloov kho. Ib qho yog kev hloov kho hydrogenation, Roj av Resin uas ntxiv ob daim ntawv cog lus hauv cov roj av resin molecule, Petroleum Resin yog li txhim kho nws cov xim thiab tiv thaiv oxidation stability. Petroleum resins nrog cov khoom tshwj xeeb tuaj yeem npaj tau los ntawm kev ntxiv pawg polar los yog hloov pauv xws li monoolefin rau cov khoom siv raw.
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.
