He aha ka petroleum resin? He aha nā ʻāpana nui?

2022-10-26

ʻO ka Petroleum resin kahi ʻano epoxy resin me ke kaumaha molekala haʻahaʻa. ʻOi aku ka haʻahaʻa o ka paona molekala ma mua o 2000. Loaʻa iā ia ka ductility thermal a hiki ke hoʻoheheʻe i nā mea hoʻoheheʻe, ʻoi aku ka nui o nā mea hoʻoheheʻe ʻaila ʻaila. He kūpono maikaʻi me nā mea resin ʻē aʻe. Loaʻa iā ia ke kūpaʻa abrasion kiʻekiʻe a me ke kūpaʻa ʻelemakule. ʻO kāna mau ʻāpana hana koʻikoʻi e pili ana i ka wahi palupalu, hue, unsaturation, waiwai waika, waiwai saponification, pili pili, a pēlā aku.

ʻO ka wahi palupalu kahi hiʻohiʻona nui o ka resin petroleum, ʻo ia hoʻi he ʻokoʻa kona ikaika, brittleness, a me ka viscosity me ka noi, a ʻokoʻa hoʻi ka wahi palupalu i koi ʻia. Ma lalo o nā kūlana maʻamau, ʻo 70 ° C a hiki i 1000 ° C ka mea palupalu i ka hana ʻana i ka ʻoihana ʻenehana, a ʻo ka wahi palupalu i ka hana ʻana o nā uhi a me nā pena he 100 ° C a 1200 ° C.

Eia kekahi, ʻo ke kiʻekiʻe o ka hoʻololi tonal i hoʻokumu ʻia e ka kukui ultraviolet a me nā hopena wela he mea koʻikoʻi loa ka hana hana. ʻAʻole hiki ke hoʻohana ʻia ka waiwai waika no ka ʻike ʻana i ka hiki ke mālama ʻia o nā mea hoʻoheheʻe metala acid-base akā no ka ʻike pū ʻana i nā ʻāpana carbonyl a me ka carboxyl o ka waiho ʻana o ka resin petroleum ma muli o kāna oxidation.

He paʻakikī loa ka hana ʻana o ka petroleum resin. Me ka kūʻai ʻana a me ka hoʻolaha ʻana i kāna mau hoʻohana nui, ʻoi aku ka nui o nā ʻano, hiki ke hoʻokaʻawale ʻia i ʻelima mau ʻāpana:

â  ʻO ka momona o ke kino kanaka, cycloaliphatic epoxy resin, maʻamau i hoʻomākaukau ʻia mai ka hakina C5, ʻike ʻia hoʻi ʻo C5 epoxy resin;

â¡ p-xylene epoxy resin, hana ma'amau mai ka hakina C9, i kapa 'ia 'o C9 epoxy resin;

⢠p-xylene-aliphatic hydrocarbon copolymer epoxy resin, i ʻike ʻia ʻo C5/C9 epoxy resin;

â£Dicyclopentadiene epoxy resin, i hana ʻia mai ka dicyclopentadiene a i ʻole kona mau pūhui, ua kapa ʻia ʻo DCPD epoxy resin. No ka mea he mau pūʻulu hydrocarbon aliphatic unsaturated kēia resin epoxy, ua kapa ʻia nō hoʻi ia i ke apo reflective Oxygen resin.

⤠Hydrocracking petroleum resin, maʻamau C5 a i ʻole C9 epoxy resin he ʻulaʻula ʻulaʻula i ka melemele māmā a hiki ke lilo i keʻokeʻo waiū a i ʻole translucent ma hope o ka hydrocracking.

Hoʻohana nui ʻia ka Petroleum resin i nā hale kūkulu hale, adhesives, paʻi inika, preservatives, a me nā mea i hoʻololi ʻia i ka vulcanized rubber. Me ka ulu mau ʻana o ka ʻenehana resin, ke hoʻomau mau nei kāna mau hoʻohana nui. ʻO C5 epoxy resin kahi ʻāpana me ka wikiwiki o ka hoʻomohala ʻana i kēia pae, a ua hoʻohana nui ʻia i nā hale kūkulu hale, paʻi inika, sila, hoʻopaʻa a me nā ʻoihana ʻē aʻe. Hoʻohana nui ʻia ka C9 epoxy resin i ka pena, ka vulcanized rubber, plastic a me nā ʻoihana ʻē aʻe, a ʻo kona hoʻomohala ʻana a me ka hoʻolālā ʻana i ka mākeke ākea ākea.
