C9 roj av resin yog ib qho thermoplastic cob uas ua los ntawm kev tawg cov khoom los ntawm C9 feem ntawm ethylene ntau lawm chav tsev ua cov khoom siv tseem ceeb, Petroleum Resin polymerizing nws nyob rau hauv lub xub ntiag ntawm ib tug catalyst, Petroleum Resin los yog copolymerizing nws nrog aldehydes, aromatic hydrocarbons, terpenes. Nws cov molecular loj yog feem ntau tsawg dua 2000, Petroleum Resin softening point yog tsawg dua 150 âº, Petroleum Resin nws yog ib qho thermoplastic viscous kua lossis khoom. Vim nws qhov qis softening point thiab qhov hnyav molecular me me, Petroleum Resin feem ntau tsis siv ib leeg los ua cov khoom siv.
Nrog rau txoj kev loj hlob ntawm kev tshawb fawb niaj hnub thiab thev naus laus zis, tshwj xeeb tshaj yog kev nce qib ntawm kev tshawb fawb thev naus laus zis, Petroleum Resin txoj kev loj hlob ntawm roj av resin tau nkag mus rau lub sijhawm ntawm kev sib tw thev naus laus zis. Ntau lub tuam txhab txawv teb chaws tau muab kev saib xyuas tag nrho rau kev lag luam, thev naus laus zis, Petroleum Resin ib puag ncig thiab lwm yam, tsom mus rau kev txhim kho cov khoom lag luam thiab nthuav dav daim ntawv thov ntau yam ntawm cov khoom. Kev hloov kho ntawm C9 roj av resin feem ntau yog tsim los ntawm ob qho kev qhia: kev xaiv cov khoom tshwj xeeb lossis cov ntaub ntawv hloov kho thiab C9 feem rau copolymerization, Petroleum Resin uas yog, Petroleum Resin tshuaj hloov kho; Tom qab cov resin yog polymerized, nws yog hydrogenated, uas yog hydrogenated hloov.
Kev hloov kho tshuaj: Los ntawm kev qhia pawg polar hauv C9 roj av resin, Petroleum Resin compatibility thiab dispersibility nrog polar tebchaw tuaj yeem txhim kho. Cov khoom siv tau los ua cov dej zoo stabilizer thiab thickener. Piv txwv li, Petroleum Resin cov resin tau hloov kho nrog cov txiv neej anhydride los npaj cov dej-soluble resin: phenolic tshuaj tau yooj yim muab tso rau hauv vinyl aromatic hydrocarbon polymer. Cov tshuaj phenolic yog siv los ua cov kuab tshuaj catalyst los txhim kho cov polarity ntawm cov resin thiab txhawb kev sib tov thiab disperse nrog lwm cov resins.
Kev hloov kho hydrogenation: Cov roj av C9 feem ntau yog xim av lossis xim av, Petroleum Resin uas txwv nws daim ntawv thov. Tom qab hydrogenation, Petroleum Resin thawj ob daim ntawv cog lus hauv cov resin raug rhuav tshem, tsim ib daim ntawv cog lus. Cov resin ua tsis muaj xim thiab tsis muaj ntxhiab tsw tshwj xeeb. Nws tseem tuaj yeem txhim kho nws cov huab cua tiv thaiv, adhesion, Petroleum Resin stability thiab lwm yam khoom, ntxiv nthuav nws daim ntawv thov teb. Qhov no yuav yog lub hom phiaj ntawm kev txhim kho yav tom ntej hauv kev lag luam roj av.
