ICarbon Nine Petroleum Resin yiresin ye-thermoplastic efunyenwe ngokwahlula-hlula imveliso ye-carbon elithoba yesityalo se-ethylene kwizixhobo eziphambili, i-petroleum Resin ipholisa phambi kwe-catalyst, i-petroleum Resin okanye i-copolymerizing nge-aldehydes, i-hydrocarbons enevumba elimnandi, i-terpenes. Ubunzima bayo bemolekyuli ngokubanzi bungaphantsi kwama-2000, indawo yokuthambisa yePetroleum Resin ingaphantsi kwe-150 â, lulwelo lwe-thermoplastic viscous okanye oluqinileyo. Ngenxa yeendawo zayo zokuthambisa ezisezantsi kunye nobunzima bemolekyuli encinci, iPetroleum Resin ayisetyenziswa yodwa njengesixhobo. Ngenxa yokuba ulwakhiwo lwe-carbon ye-petroleum resin ayiqulathanga maqela e-polar, inokumelana kakuhle namanzi, i-asidi kunye nokumelana ne-alkali, ukumelana nemozulu kunye nokumelana nokuguga okukhanyayo, i-petroleum Resin yokunyibilika kakuhle kwizinyibilikisi zezinto eziphilayo, kunye nokuhambelana kakuhle nezinye iintlaka. , ukubamba, ukuncamathela kwePetroleum Resin kunye neplastikhi, kwaye isetyenziswa ikakhulu kumasimi okwambathisa, izongezo zerabha, izongezo zephepha lePetroleum Resin, ii-inks zePetroleum Resin kunye nezinto zokuncamathelisa, kwaye inemfuno enkulu yentengiso.
Imathiriyeli ekrwada yepetroleum resin eqhekekileyo ikhabhoni elithoba iqhezu ngumxube ontsonkothileyo weentlobo ezingaphezu kwe-150 zamacandelo e-hydrocarbon anevumba elimnandi elinendawo yokubilisa kuluhlu lwama-240 â, ngaphandle kokwakheka okumiselweyo, i-petroleum Resin kwaye isasazeke kakhulu kwaye ayihlali. kulula ukwahlula. Ngokombono we-synthesis, i-Petroleum Resin inokwahlulwa ibe ngamacandelo amabini. Olunye uhlobo lwamacandelo asebenzayo anokuthi afakwe i-polymerized, njenge: styrene kunye ne-vinyl toluene, i-dicyclopentadiene, i-Petroleum Resin njl.; olunye uhlobo lwamacandelo angasebenziyo, njenge-alkylbenzene kunye ne-fused ring hydrocarbons enevumba elimnandi, njl. njl Ikhabhoni imathiriyeli ekrwada esithoba iqulathe malunga ne-50% yeemonomerizable monomers.
Iindlela eziqhelekileyo zokwenziwa kweereyini zepetroleum yi-polymerization eshushu, i-catalytic polymerization, i-Petroleum Resin kunye ne-polymerization yasimahla. Phakathi kwezinto ezininzi ezibonakalayo kunye neekhemikhali ze-petroleum resin, eyona nto ibalulekileyo yindawo yokuthambisa kunye ne-hue. Indawo yokuthambisa kufuneka ibe yi-50-140 ° C, i-hue ingaphantsi kwe-l3, i-Petroleum Resin kunye nokukhanya okutyheli ukuya kumdaka omnyama. Indlela ye-polymerization ye-carbon nine fraction inefuthe elikhulu kwi-hue kunye ne-softening point of carbon nine petroleum resin.
