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. Cov yam ntxwv ntawm cationic polymerization yog cov tshuaj tiv thaiv tus nqi. Fast, Petroleum Resin lub catalyst yog ib qho yooj yim los txiav tawm cov tshuaj tiv thaiv vim muaj yam xws li impurities lossis molecular qauv hauv cov khoom siv raw, yog li nws tuaj yeem ua polymerized rau hauv ib lub polymer nrog ib qho hnyav molecular ntawm 500 txog 2,000, Petroleum Resin uas txhim kho cov viscosity nce. nyhuv.
Muaj ob peb kauj ruam tseem ceeb hauv cov txheej txheem ntawm roj av resin-xaiv thiab kev kho ua ntej ntawm cov roj nyoos, Roj av resin polymerization ntawm cov khoom siv raw, nruab nrab thiab kev sib cais ntawm cov resin. Ntawm lawv, Petroleum Resin kev kho mob ua ntej yog qhov tseem ceeb tshaj plaws, txhawm rau tshem tawm cov ntaub ntawv tsis zoo ua ntej Xaiv cov txau nrog cov sib xyaw sib txawv los kho cov khoom ntawm cov roj av resin; Roj av Resin lossis cua sov kom ua tiav cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv tseem ceeb nyob rau hauv cov txheej txheem yog tag nrho los yog txheeb ze concentration ntawm cov pub, Petroleum Resin hom catalyst thiab nws cov concentration, thiab kub. Cov khoom saum toj no yuav tsum tau ua tib zoo tswj Kom tau txais txiaj ntsig zoo, Petroleum Resin molecular hnyav thiab molecular hnyav faib.
Txoj kev polymerization tuaj yeem muab faib ua batch hom, Petroleum Resin nruam hom, thiab ntau hom kev txuas mus ntxiv. Ntawm lawv, qhov ntsuas qhov hnyav molecular ntawm cov tshuaj tiv thaiv batch yog dav dua, Petroleum Resin thiab ntau cov kauj ruam txuas ntxiv muaj cov txiaj ntsig ntau dua thiab nqaim molecular hnyav faib. Cov ntaub ntawv raw yog tsim nyob rau hauv cov txheej txheem roj av Nws yog ib qho tseem ceeb heev. Los ntawm kev kho cov roj pub ntawm cov feem sib txawv, Petroleum Resin cov qauv molecular thiab cov yam ntxwv ntawm cov khoom tiav tuaj yeem hloov kho. Piv txwv li, Petroleum Resin C5 thiab C9 yog copolymerized los yog ib co ntshiab monomers ntxiv raws li kev hloov kho, ntxiv rau kev kho cov roj av cob Rau cov polarity los yog acid tus nqi ntawm cov khoom tiav, Petroleum Resin chemical compositions xws li maleic anhydride (MA), phenol thiab rosin kuj tuaj yeem muab ntxiv rau cov khoom siv raw, Petroleum Resin lossis roj av resin tuaj yeem raug grafted nrog acid radicals los ntawm grafting mis.
