Carbon Nine Petroleum Resin yog ib qho thermoplastic cob tau los ntawm kev faib cov khoom los ntawm carbon cuaj distillate ntawm ethylene cog rau hauv cov ntaub ntawv 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, nws yog cov 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. Vim tias cov qauv ntawm carbon cuaj roj av resin tsis muaj cov polar pawg, nws muaj dej tsis kam, acid thiab alkali tsis kam, huab cua tsis kam thiab lub teeb aging kuj, Petroleum Resin zoo solubility hauv cov kuab tshuaj organic, thiab zoo sib xws nrog lwm cov resins Nws kuj muaj brittleness. , tackiness, Petroleum Resin adhesion thiab plasticity, thiab yog tsuas yog siv nyob rau hauv lub teb ntawm coatings, roj hmab additives, Roj av Resin ntawv additives, Roj av Resin inks thiab adhesives, thiab muaj ib tug loj kev lag luam xav tau.
Cov khoom siv raw ntawm cov roj av resin tawg cov pa roj carbon cuaj feem yog cov sib xyaw ua ke ntawm ntau dua 150 hom tshuaj tsw qab hydrocarbon cov ntsiab lus nrog lub rhaub dej kub hauv qhov ntau ntawm 240 â, tsis muaj qhov sib xyaw ruaj khov, Petroleum Resin thiab nws yog dispersed heev thiab tsis. yooj yim cais. Los ntawm qhov kev xav ntawm kev sib txuas, Petroleum Resin tuaj yeem muab faib ua ob pawg. Ib hom khoom siv uas tuaj yeem ua tau polymerized, xws li: styrene thiab vinyl toluene, dicyclopentadiene, Petroleum Resin thiab lwm yam.; Lwm yam khoom tsis muaj zog, xws li alkylbenzene thiab fused nplhaib uas muaj ntxhiab hydrocarbons, thiab lwm yam.Petroleum Resin ua cov kuab tshuaj thaum lub sijhawm polymerization Tom qab cov tshuaj tiv thaiv yog distilled. Cov pa roj carbon cuaj cov khoom siv feem ntau muaj li 50% ntawm polymerizable monomers.
Feem ntau txoj hauv kev los ua cov roj av resins yog thermal polymerization, catalytic polymerization, Roj av Resin thiab dawb radical polymerization. Ntawm ntau lub cev thiab tshuaj lom neeg ntawm cov roj av resin, qhov tseem ceeb tshaj plaws yog qhov muag muag thiab xim. Lub softening point yuav tsum yog 50-140 ° C, lub xim yog tsawg dua l3, Roj av Resin thiab lub teeb daj mus rau tsaus xim av. Cov txheej txheem polymerization ntawm carbon cuaj feem muaj qhov cuam tshuam zoo rau cov xim daj thiab softening point ntawm carbon cuaj petroleum resin.
