ʻO Carbon Nine Petroleum Resin kahi resin thermoplastic i loaʻa ma ka hoʻokaʻawale ʻana i ka huahana carbon nine distillate o ka mea kanu ethylene i nā kumu waiwai nui, Petroleum Resin polymerizing ia i mua o kahi catalyst, Petroleum Resin a i ʻole copolymerizing me nā aldehydes, aromatic hydrocarbons, terpenes. ʻOi aku ka liʻiliʻi o kāna molecular mass ma mua o 2000, ʻoi aku ka liʻiliʻi o ka Petroleum Resin ma lalo o 150 â, he wai thermoplastic viscous a paʻa paha. Ma muli o kona haʻahaʻa haʻahaʻa haʻahaʻa a me ka liʻiliʻi liʻiliʻi molecular paona, Petroleum Resin ʻaʻole i hoʻohana wale ʻia ma ke ʻano he mea. No ka mea, ʻaʻole i loaʻa i nā hui polar ke ʻano o ka carbon nine petroleum resin, maikaʻi ke kūpaʻa wai, ka wai a me ke kūpaʻa alkali, ka pale ʻana i ka wā a me ka pale ʻana o ka ʻelemakule, Petroleum Resin maikaʻi ka solubility i nā mea hoʻoheheʻe organik, a me ka launa pū me nā resins ʻē aʻe. , Tackiness, Petroleum Resin adhesion a me ka plasticity, a ua hoʻohana nui ʻia i loko o nā māla o nā uhi, nā mea hoʻohui i ka lāʻau, nā mea hoʻohui pepa Petroleum Resin, nā inika Petroleum Resin a me nā adhesives, a he koi nui ka mākeke.
ʻO ka mea maka o ka petroleum resin cracked carbon nine fraction he hui paʻakikī o ka ʻoi aku ma mua o 150 mau ʻano o nā ʻāpana hydrocarbon aromatic me kahi paila i loko o ka laulā o 240 â, me ka ʻole o ka haku mele, Petroleum Resin a ua hoʻopuehu loa a ʻaʻole. oluolu e hookaawale. Mai ka hiʻohiʻona o ka synthesis, Petroleum Resin hiki ke hoʻokaʻawale ʻia i ʻelua mau ʻāpana. ʻO kekahi ʻano o nā mea hana i hiki ke polymerized, e like me: styrene a me vinyl toluene, dicyclopentadiene, Petroleum Resin etc.; ʻO kekahi ʻano o nā ʻāpana hana ʻole, e like me alkylbenzene a me fused ring aromatic hydrocarbons, etc. Petroleum Resin e hana ma ke ʻano he mea hoʻoheheʻe i ka wā polymerization Ma hope o ka hoʻoheheʻe ʻia ʻana o ka hopena. Loaʻa ma kahi o 50% o nā monomers polymerizable ka carbon eiwa maka.
ʻO nā ala maʻamau no ka synthesizing petroleum resins he thermal polymerization, catalytic polymerization, Petroleum Resin a me free radical polymerization. Ma waena o nā waiwai kino a me nā kemika o ka petroleum resin, ʻo ka mea nui ka wahi palupalu a me ka hue. Pono ka wahi palupalu i 50-140 ° C, ʻoi aku ka liʻiliʻi o ka hue ma mua o l3, Petroleum Resin a me ka melemele māmā i ka ʻeleʻele ʻeleʻele. ʻO ke ʻano polymerization o ka hakina kalapona ʻeiwa he mana nui i ka hue a me ka wahi palupalu o ka resin petroleum carbon nine.
