ʻO nā ʻaila hinu (hydrocarbon resin)
ʻO ka Petroleum resin kahi huahana kemika hou i kūkulu ʻia i nā makahiki i hala iho nei. Ua kapa ʻia ʻo ia ma muli o ke kumu o ka ʻaila ʻaila. Loaʻa iā ia nā hiʻohiʻona o ka waiwai haʻahaʻa haʻahaʻa, miscibility maikaʻi, kūpaʻa wai, kūpaʻa ethanol a me ke kūpaʻa kemika, a me ke kūpaʻa kemika maikaʻi i ka waikawa a me ka alkali. , a loaʻa ka hoʻoponopono viscosity maikaʻi a me ke kūpaʻa wela, ke kumu kūʻai haʻahaʻa. ʻAʻole hoʻohana wale ʻia nā resins Petroleum, akā hoʻohana pū ʻia e like me nā accelerators, regulators, modifiers a me nā resins ʻē aʻe. Hoʻohana nui ʻia i ka lāʻau, adhesives, coatings, pepa, inika a me nā ʻoihana ʻē aʻe a me nā māla.
ʻO ka mea maʻamau, hiki ke hoʻokaʻawale ʻia e like me C5 aliphatic, C9 aromatic (hydrocarbons aromatic), DCPD (cycloaliphatic, cycloaliphatic) a me nā monomers maʻemaʻe e like me poly SM, AMS (alpha methyl styrene) a me nā ʻano ʻehā ʻē aʻe o nā huahana. , no laila ua kapa ʻia ʻo ia he hydrocarbon resins (HCR).
Wahi a nā ʻano mea like ʻole, ua māhele ʻia i loko o Asiatic resin (C5), alicyclic resin (DCPD), aromatic resin (C9), aliphatic/aromatic copolymer resin (C5/C9) a me hydrogenated petroleum resin. C5 hydrogenated petroleum resin, C9 hydrogenated petroleum resin
ʻO nā mea i hoʻohana nui ʻia
C9 petroleum resin e pili pono ana i kahi mea resinous i loaʻa ma ka "polymerizing olefins or cyclic ole fins a copolymerizing with aldehydes, aromatic hydrocarbons, terpenes, etc." ʻeiwa mau ʻātoma kalapona.
ʻO C9 petroleum resin, i ʻike ʻia he resin aromatic, ua māhele ʻia i ka polymerization thermal, polymerization anuanu, tar a pēlā aku. I waena o lākou, ʻo ka huahana polymerization anuanu he māmā i ke kala, maikaʻi i ka maikaʻi, a he 2000-5000 ka nui o ka molecular weight. ʻO ka melemele māmā a i ka ʻulaʻula ʻulaʻula, granular a paʻa nui paha, ʻālohilohi a ʻālohilohi, pili pili 0.97~1.04.
ʻO 80~140â ka helu palupalu. ʻO ka mahana hoʻololi aniani he 81°C. Hōʻike hoʻohālikelike 1.512. kiko uila 260 â. Waiwai ʻakika 0.1~1.0. ʻO ka waiwai iodine he 30-120. Hiki ke hoʻoheheʻe ʻia i ka acetone, methyl ethyl ketone, cyclohexane, dichloroethane, ethyl acetate, toluene, gasoline, etc.
ʻAʻole hiki ke hoʻoheheʻe ʻia i ka ethanol a me ka wai. He ʻano pōʻaiapuni kona, loaʻa kekahi mau mea paʻa pālua, a paʻa ka pilina paʻa. ʻAʻohe pūʻulu polar a i ʻole nā hui hana i loko o ka molecular structure a ʻaʻohe hana kemika. Loaʻa ka maikaʻi o ka waikawa a me ka alkali, ka pale kemika a me ka pale wai.
ʻAʻole pono e hoʻohana wale ʻia ka adhesion maikaʻi ʻole, brittleness, a me ka pale ʻana i ka wā kahiko. Hoʻopili maikaʻi me ka resin phenolic, coumarone resin, terpene resin, SBR, SIS, akā maikaʻi ʻole ka launa pū me nā polymers non-polar ma muli o ka polarity kiʻekiʻe. Hiki ke ahi. Nontoxic.
Me kona ʻili kiʻekiʻe a me ka ikaika hoʻopaʻa ʻana, ka wikiwiki wikiwiki, ka hana hoʻopaʻa paʻa, ka viscosity hoʻoheheʻe haʻahaʻa, ka pale wela maikaʻi, ka hoʻohālikelike maikaʻi me ka polymer matrix, a me ke kumu kūʻai haʻahaʻa, hoʻomaka ia e hoʻololi i ka resin kūlohelohe e hoʻonui i nā mea viscosity (rosin a me terpene resins. ).
ʻO nā hiʻohiʻona o ka resin petroleum C5 i hoʻomaʻemaʻe ʻia i nā mea hoʻoheheʻe wela: ka wai maikaʻi, hiki ke hoʻomaikaʻi i ka wettability o ka mea nui, viscosity maikaʻi, a me ka hana tack mua. ʻOi aku ka maikaʻi o nā waiwai anti-kahiko, ka waihoʻoluʻu māmā, ke aniani, ka ʻala haʻahaʻa, nā volatiles haʻahaʻa. I nā mea hoʻoheheʻe wela, hiki ke hoʻohana wale ʻia ka moʻo ZC-1288D e like me ka tackifying resin a i hui pū ʻia me nā resins tackifying ʻē aʻe e hoʻomaikaʻi i kekahi mau ʻano o nā mea hoʻoheheʻe wela.
Paʻa hoʻoheheʻe wela:
ʻO ka resin kumu o ka hoʻoheheʻe wela wela ka ethylene a me ka vinyl acetate copolymerized ma lalo o ke kiʻekiʻe kiʻekiʻe a me ke kaomi kiʻekiʻe, ʻo ia ka EVA resin. ʻO kēia resin ka mea nui no ka hana ʻana i ka mea hoʻoheheʻe wela wela. ʻO ka māhele a me ka maikaʻi o ka resin kumu e hoʻoholo i nā waiwai kumu o ka mea hoʻoheheʻe wela wela.
Heluhelu helu (MI) 6-800, haʻahaʻa VA maʻiʻo, ʻoi aku ka kiʻekiʻe o ka crystallinity, ʻoi aku ka kiʻekiʻe o ka paʻakikī, ma lalo o nā kūlana like, ʻoi aku ka nui o ka waihona VA, ʻoi aku ka haʻahaʻa o ka crystallinity, ʻoi aku ka elastic ʻilihune i ka pulu ʻana a me ka permeability o nā mea pili.
ʻO ka mea ʻē aʻe, inā ʻoi aku ka nui o ka helu hoʻoheheʻe, haʻahaʻa ka wela hoʻoheheʻe ʻana o ke kāpili, maikaʻi ka wai, akā hoʻemi ʻia ka ikaika paʻa. ʻO ke koho ʻana i kāna mea hoʻohui pono e koho i ka ratio kūpono o ka ethylene a me ka vinyl acetate.
Nā polokalamu ʻē aʻe:
1. Pena
Hoʻohana nui ka pena i ka resin petroleum C9, resin DCPD a me ka resin copolymer C5/C9 me kahi wahi palupalu kiʻekiʻe. ʻO ka hoʻohui ʻana i ka resin petroleum i ka pena hiki ke hoʻonui i ka nani o ka pena, hoʻomaikaʻi i ka pili ʻana, ka paʻakikī, ka pale ʻana i ka waikawa a me ke kūpaʻa alkali o ke kiʻi pena.
2. Lapa
Hoʻohana nui ka Rubber i ka wahi palupalu haʻahaʻa C5 petroleum resin, C5/C9 copolymer resin a me DCPD resin. ʻO ia mau resins ka mea hiki ke hoʻoheheʻe maikaʻi ʻia me nā ʻāpana kopa maoli, a ʻaʻohe mana nui i ke kaʻina hana vulcanization o ka lāʻau. Hiki ke hoʻonui i ka viscosity, hoʻoikaika a palupalu ka hoʻohui ʻana i ka petroleum resin i ka lāʻau. ʻO ka mea nui, ʻaʻole hiki i ka hoʻohui ʻana o ka resin copolymer C5 / C9 ke hoʻonui i ka hoʻopili ʻana ma waena o nā ʻāpana lāʻau, akā hoʻomaikaʻi hoʻi i ka adhesion ma waena o nā ʻāpana a me nā kaula. He kūpono ia no nā huahana kāpili me nā koi kiʻekiʻe e like me nā kaila radial.
3. ʻOihana hoʻopili
He maikaʻi ka hoʻopili ʻana o ka resin petroleum. ʻO ka hoʻohui ʻana i ka resin petroleum i nā adhesives a me nā lipine pili i ka puʻuwai hiki ke hoʻomaikaʻi i ka ikaika adhesive, ka pale ʻana i ka waikawa, ke kūpaʻa alkali a me ka pale wai o ka adhesive, a hiki ke hoʻemi pono i ke kumukūʻai hana.
4. ʻOihana Inika
ʻAla ʻaila resins
5. ʻoihana uhi
ʻO nā uhi no nā hōʻailona alanui a me ka mākaʻikaʻi ʻana o ke alanui, ʻoi aku ka maikaʻi o ka resin petroleum i ka palaki a i ʻole ka asphalt pavement, a maikaʻi ke pale ʻana i ka ʻaʻahu a me ka pale wai, a he pilina maikaʻi me nā mea inorganic, maʻalahi ke kapa, maikaʻi ke kū kūʻē i ka wā.
ʻO ka maloʻo wikiwiki, ka paʻa kiʻekiʻe, a hiki ke hoʻomaikaʻi i nā waiwai kino a me nā kemika o ka papa, hoʻomaikaʻi i ka pale ʻana o UV a me ka pale ʻana i ka wā. Ke hele mālie nei ka peʻa ʻala ʻala ʻaila peila, a ke piʻi nei ke koi i kēlā me kēia makahiki.
6. ʻO nā mea ʻē aʻe
Loaʻa i ka Resin kahi ʻano o ka unsaturation a hiki ke hoʻohana ʻia e like me ka mea hoʻohana pepa, mea hoʻololi plastic, etc.
7.
E mālama i loko o kahi ea, anuanu a maloʻo. Hoʻokahi makahiki ka manawa mālama, a hiki ke hoʻohana ʻia ma hope o hoʻokahi makahiki inā hala ka nānā ʻana.
