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. Chifukwa cha kufewetsa kwake kochepa komanso kulemera kochepa kwa maselo, Petroleum Resin nthawi zambiri sagwiritsidwa ntchito ngati chinthu.
Ndi chitukuko cha sayansi yamakono ndi teknoloji, makamaka kupita patsogolo kwa teknoloji yowunikira, Petroleum Resin chitukuko cha petroleum resin chalowa mu nthawi ya mpikisano wamakono. Opanga osiyanasiyana akunja aganizira mozama pazachuma, ukadaulo, chilengedwe cha Petroleum Resin ndi zinthu zina, kuyang'ana kwambiri pakuwongolera magwiridwe antchito ndikukulitsa kuchuluka kwazinthu zomwe zimagwiritsidwa ntchito. Kusintha kwa C9 petroleum resin makamaka kumachitika mbali ziwiri: kusankha kwa zida zapadera kapena zida zosinthidwa ndi kagawo kakang'ono ka C9 ka copolymerization, Petroleum Resin ndiko kuti,Petroleum Resin chemical modification; utomoni utatha kupangidwa ndi polymerized, umakhala ndi hydrogenated, womwe umasinthidwa ndi hydrogenated.
Kusintha kwa Chemical: Poyambitsa magulu a polar mu C9 petroleum resin, Petroleum Resin yogwirizana ndi dispersibility ndi mankhwala polar akhoza kusintha. Mankhwalawa amatha kugwiritsidwa ntchito ngati stabilizer yamadzi ndi thickener. Mwachitsanzo, utomoni wa Petroleum utomoni umasinthidwa ndi maleic anhydride kuti ukonze utomoni wosungunuka m'madzi: zinthu za phenolic zimaphatikizidwa mosavuta mu vinyl onunkhira hydrocarbon polima. Mankhwala a phenolic amagwiritsidwa ntchito ngati zosungunulira zosungunulira kuti apititse patsogolo polarity ya utomoni ndikulimbikitsa Sakanizani ndikubalalitsa ndi ma resin ena.
Kusintha kwa Hydrogenation: Common C9 petroleum resin nthawi zambiri imakhala yofiirira kapena yofiirira, Petroleum Resin yomwe imachepetsa kugwiritsa ntchito kwake. Pambuyo pa hydrogenation, Petroleum Resin chomangira choyambirira chapawiri mu utomoni chimawonongeka, ndikupanga chomangira chimodzi. Utoto umakhala wopanda mtundu ndipo ulibe fungo lapadera. Ithanso kukonza kukana kwake kwanyengo, kumamatira, kukhazikika kwa Petroleum Resin ndi zinthu zina, kukulitsa gawo lake logwiritsa ntchito. Ichi chidzakhala cholinga cha chitukuko chamtsogolo m'munda wa petroleum resin.
