Carbon Nine Petroleum Resin ndi thermoplastic resin yomwe imapezedwa pogawanitsa kaboni nine distillate ya ethylene kukhala zopangira zazikulu, Petroleum Resin polima pamaso pa chothandizira, Petroleum Resin kapena copolymerizing ndi aldehydes, onunkhira ma hydrocarbons, terpenes. Mamolekyu ake nthawi zambiri amakhala osakwana 2000, Petroleum Resin softening point ndi osakwana 150 â, ndi thermoplastic viscous liquid kapena solid. Chifukwa cha kufewetsa kwake kochepa komanso kulemera kochepa kwa maselo, Petroleum Resin nthawi zambiri sagwiritsidwa ntchito ngati chinthu. Chifukwa kapangidwe ka kaboni nine petroleum resin mulibe magulu a polar, imakhala ndi kukana kwamadzi bwino, asidi ndi alkali kukana, kukana nyengo komanso kukana kukalamba, Petroleum Resin kusungunuka kwabwino mu zosungunulira za organic, komanso kumagwirizana bwino ndi utomoni wina Imakhalanso ndi brittleness. , tackiness, Petroleum Resin adhesion and plasticity, ndipo amagwiritsidwa ntchito makamaka m'minda ya zokutira, zowonjezera mphira, zowonjezera mapepala a Petroleum Resin, inki ndi zomatira za Petroleum Resin, ndipo zimafuna msika waukulu.
Mafuta a petroleum resin osweka kaboni naini kagawo kakang'ono kagawo kakang'ono ka mitundu yopitilira 150 yamafuta onunkhira a hydrocarbon okhala ndi malo otentha apakati pa 240 â, popanda mawonekedwe osakhazikika, Petroleum Resin ndipo amamwazika kwambiri osati zosavuta kupatukana. Malinga ndi kaphatikizidwe, Petroleum Resin itha kugawidwa m'magulu awiri. Mtundu umodzi wa zigawo yogwira kuti akhoza polymerized, monga: styrene ndi vinilu toluene, dicyclopentadiene, Petroleum utomoni etc.; mtundu wina wa anafooka zigawo zikuluzikulu, monga alkylbenzene ndi anasakaniza mphete onunkhira hydrocarbons, etc.Petroleum utomoni monga solvents pa polymerization Pambuyo anachita ndi distilled. Zopangira kaboni zisanu ndi zinayi nthawi zambiri zimakhala ndi pafupifupi 50% ya ma polymerizable monomers.
Njira zodziwika bwino zopangira utomoni wa petroleum ndi polymerization yamafuta, catalytic polymerization, Petroleum Resin ndi polymerization yaulere. Pakati pa zinthu zambiri zakuthupi ndi zamankhwala za utomoni wa petroleum, chofunikira kwambiri ndikufewetsa ndi mtundu wake. Kufewetsa kumafunika kukhala 50-140 ° C, mtundu wake ndi wochepera l3, Petroleum Resin ndi kuwala chikasu mpaka bulauni. Njira ya polymerization ya kagawo kakang'ono ka kaboni naini imakhala ndi chikoka chachikulu pamtundu komanso kufewetsa kwa carbon 9 petroleum resin.
