Utoto wamafuta utha kugwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana,Utomoni wamafuta monga utoto, mphira, ndi zina zambiri. Chifukwa chiyani utomoni wamafuta ndi wodziwika kwambiri?
Pali njira ziwiri zazikulu zosinthira. Imodzi ndi hydrogenation modification, Petroleum Resin yomwe imawonjezera mgwirizano wapawiri mu molekyulu ya petroleum resin, Petroleum Resin potero imapangitsa kuti mtundu wake ukhale wolimba komanso kukhazikika kwa anti-oxidation. Mafuta a petroleum okhala ndi katundu wapadera amatha kukonzedwa powonjezera magulu a polar kapena zosintha monga monoolefin ku zipangizo.
Kagawo kakang'ono ka C9 kamakhala ndi mankhwala onunkhira a hydrocarbon monga vinyl toluene, inde, methylstyrene, Petroleum Resin etc.
Kukonzekera kwa C9 petroleum resin ndi motere: zopangira zimayikidwa kale kuti zichotse (bis) cyclopentadiene ndi isoprene,Petroleum Resin kuti mupeze zopangira zokhala ndi gawo lalikulu lopitilira 50%,Petroleum Resin ndikuwonjezera kununkhira konunkhira kwa hydrocarbon. motetezedwa ndi nayitrogeni,Petroleum Resin Kenako yikani chothandizira AlCl3.
Chitukuko cha C9 petroleum resin kupanga kunyumba ndi kunja: chitukuko cha mafakitale a petrochemical chimapereka zipangizo zolemera komanso zotsika mtengo zopangira mafuta a petroleum resin, Petroleum Resin kotero kuti kupanga mafuta a petroleum resin m'mayiko otukuka a petrochemical kukukula mofulumira.
C9 petroleum resin ndi thermoplastic resin yomwe imapangidwa pophwanya kachigawo kakang'ono ka C9 kagawo kakang'ono ka ethylene monga chopangira chachikulu, Petroleum Resin polima pamaso pa chothandizira, Petroleum Resin kapena copolymerizing ndi aldehydes, ma hydrocarbon onunkhira, terpenes. Ma molekyulu ake nthawi zambiri amakhala osakwana 2000, Petroleum Resin softening point ndi osakwana 150 â, Petroleum Resin ndi madzi owoneka bwino a thermoplastic kapena olimba.
