I-C9 petroleum resin yiresin ye-thermoplastic eveliswa ngokukrazula icandelo lemveliso ye-C9 yeyunithi yokuvelisa i-ethylene njengeyona nto iphambili ekrwada, i-petroleum Resin i-polymerizing phambi kwe-catalyst, i-petroleum Resin okanye i-copolymerizing nge-aldehydes, i-hydrocarbons enuka kamnandi, i-terpenes. Ubunzima bayo bemolekyuli ngokubanzi bungaphantsi kwama-2000, indawo yokuthambisa yePetroleum Resin ingaphantsi kwe-150 â, iPetroleum Resin lulwelo lwe-thermoplastic viscous okanye oluqinileyo.
I-petroleum resin ibizwa ngokuba ivela kwi-petroleum derivatives. Ineempawu zexabiso le-asidi ephantsi, i-Petroleum Resin efanelekileyo yokungahambi kakuhle, ukunganyangeki kwamanzi, ukuxhathisa kwe-ethanol ye-Petroleum Resin kunye nokuxhathisa imichiza. Uzinzile ngokwekhemikhali kwi-acids kunye neziseko kwaye une-viscosity enhle kunye nokuzinza kwe-thermal. Iimbonakalo. I-petroleum resins ayisoloko isetyenziswa yodwa, i-Petroleum Resin kodwa njenge-accelerators, i-regulators, i-modifiers kunye nezinye ii-resin.
Izinto ezibonakalayo: Iireyini zepetroleum eziveliswa kusetyenziswa amaqhezu e-C9 kwipetroleum njengoko imathiriyeli ekrwada ibizwa ngokuba ziiC9 petroleum resins. Ifunyanwe ngokwenza i-polymerizing amaqhezu aseleyo (C8~C11) emva kokwahlula i-benzene, i-petroleum Resin toluene kunye ne-xylene kwi-oyile yokuqhekeka kwemveliso enzima. Kwiqondo lobushushu begumbi, yiglasi eqinileyo ye-thermoplastic, i-brittle, i-petroleum Resin etyheli ukuya kumdaka okhanyayo, ubunzima bemolekyuli obuphakathi 500 ~ 1000.
Izinto eziyingozi eziveliswa kukutsha kwepetroleum resin: umsi, inkungu, iPetroleum Resin carbon oxides, izinto ezingatshanga ngokupheleleyo, iPetroleum Resin kunye neehydrocarbons ezinokutsha. Izicima-mlilo kufuneka zisebenzise izixhobo ezifanelekileyo zokucima umlilo: sebenzisa inkungu yamanzi, ugwebu, iPetroleum Resin engumgubo owomileyo okanye ikharbon diokside isicima-mlilo.
Iimpawu eziphezulu zemishini. I-petroleum resin inobumbano olomeleleyo kunye nesakhiwo semolekyuli exineneyo, i-Petroleum Resin ngoko ke iipropathi zayo zoomatshini ziphezulu kuneenjongo eziqhelekileyo zokubeka i-thermosetting resin ezifana ne-phenolic resin kunye ne-polyester engafakwanga. Ukusebenza okugqwesileyo kokudibanisa.
Nangona iiresin zepetroleum zahlulwe zaba ziindidi ezine, iPetroleum Resin iindlela zokuvelisa ziphantse zifane. Ngaphandle kwezinye iireyini ze-DCPD eziveliswa yi-polymerization eshushu, i-Petroleum Resin eseleyo zonke zisetyenziswa yi-cationic polymerization. Ii-catalysts eziqhelekileyo ngamanye amaxesha zongezwa kunye ne-accelerator encinci.
