Ma Iulai 2023, ua ʻoi aku ka nui o ka epoxy resin ma Kina ma mua o 3 miliona tons i kēlā me kēia makahiki, e hōʻike ana i ka wikiwiki o ka ulu ʻana o 12.7% i nā makahiki i hala iho nei, me ka ulu ʻana o ka ʻoihana ma mua o ka awelika o ka ulu ʻana o nā kemika nui. Hiki ke ʻike ʻia i nā makahiki i hala iho nei, ua wikiwiki ka piʻi ʻana o nā hana epoxy resin, a ua nui nā ʻoihana i hoʻokomo a hoʻolālā e kūkulu i kahi papahana nui. Wahi a nā helu helu, ʻoi aku ka nui o ke kūkulu ʻana o ka epoxy resin ma Kina ma mua o 2.8 miliona tons i ka wā e hiki mai ana, a e hoʻomau ka piʻi ʻana o ka ulu ʻana o ka ʻoihana ma kahi o 18%.
ʻO ka epoxy resin ka hana polymerization o bisphenol A a me Epichlorohydrin. Loaʻa iā ia nā hiʻohiʻona o nā waiwai mechanical kiʻekiʻe, ka cohesion ikaika, ka molecular structure, ka hoʻopili maikaʻi ʻana i ka hana, ka liʻiliʻi curing shrinkage (paʻa ka nui o ka huahana, liʻiliʻi ke koʻikoʻi o loko, ʻaʻole hiki ke maʻalahi), insulation maikaʻi, kūpaʻa maikaʻi. kūpaʻa maikaʻi, a me ke kūpaʻa wela maikaʻi (a hiki i 200 ℃ a i ʻole). No laila, hoʻohana nui ʻia ia i nā uhi, nā mea uila, nā mea i hoʻohui ʻia, nā adhesives a me nā māla ʻē aʻe.

Hoʻokaʻawale ʻia ke kaʻina hana o ka epoxy resin i hoʻokahi ʻanuʻu a me ʻelua mau ala. Hoʻokahi kaʻina hana, ʻo ia ka hana ʻana i ka resin epoxy ma o ka hoʻololi pololei ʻana o ka bisphenol A a me ka Epichlorohydrin, ka mea maʻamau i hoʻohana ʻia no ka synthesize haʻahaʻa molekala haʻahaʻa a me ka medium molecular weight epoxy resin; ʻO ke ala ʻelua-ʻanuʻu e pili ana i ka hoʻomau ʻana o ka resin molecular haʻahaʻa me ka bisphenol A. Hiki ke hoʻohui ʻia ka resin epoxy kaumaha molekala kiʻekiʻe ma o nā ʻano hana hoʻokahi a i ʻole ʻelua.
ʻO ke kaʻina hana hoʻokahi, ʻo ia ka hoʻemi ʻana i ka bisphenol A a me ka Epichlorohydrin ma lalo o ka hana a NaOH, ʻo ia hoʻi, e hoʻokō i nā hopena puka apo a pani ʻia ma lalo o nā ʻano hopena like. I kēia manawa, hoʻohui ʻia ka hana nui loa o E-44 epoxy resin ma Kina ma o kahi kaʻina hana hoʻokahi. ʻO ke kaʻina hana ʻelua, ʻo ia ka bisphenol A a me Epichlorohydrin e hoʻohua i ka diphenyl propane chlorohydrin ether ma waena o ka hoʻohui ʻana i ka hana mua ma lalo o ka hana o ka catalyst (e like me Quaternary ammonium cation), a laila e hana i ka hopena pani pani i mua o ka NaOH hana i ka epoxy resin. ʻO ka pōmaikaʻi o ke ʻano hana ʻelua he manawa pōkole pōkole; ʻO ka hana paʻa, nā loli liʻiliʻi o ka mahana, maʻalahi ke kāohi; Hiki i ka manawa hoʻohui alkali pōkole ke pale i ka hydrolysis nui o epichlorohydrin. Hoʻohana nui ʻia ke kaʻina hana ʻelua no ka synthesizing resin epoxy.

Puna kiʻi: China Industrial Information
Wahi a nā helu helu pili, nui nā ʻoihana e komo i ka ʻoihana epoxy resin i ka wā e hiki mai ana. No ka laʻana, 50000 tons o Hengtai lako uila / makahiki lako e hoʻokomo 'ia i loko o ka hana i ka hopena o 2023, a me 150000 tons o mauna Huangshan Meijia hou mea / makahiki lako e hoʻokomo 'ia i loko o 'Okakopa 2023. Zhejiang Zhihe New Materials '100000 ton / Hoʻolālā ʻia nā mea hana makahiki e hoʻokomo i ka hana ma ka hopena o 2023, South Asia Electronic Materials (Kunshan) Co., Ltd. manao e hookomo i loko o ka hana 300000 ton / makahiki lako a me nā lako a puni 2025, a me Yulin Jiuyang High tech Materials Co., Ltd. manao e hookomo i ka hana 500000 ton / makahiki lako a puni 2027. E like me ka pau ole. helu, e pālua ia i ka wā e hiki mai ana ma kahi o 2025.

No ke aha e hoʻolilo ai nā mea a pau i nā papahana resin epoxy? ʻO nā kumu o ka loiloi penei:
ʻO ka epoxy resin kahi mea hoʻopili uila maikaʻi loa
ʻO ka mea hoʻopaʻa uila e pili ana i kahi pūʻulu o nā mea hoʻopili uila a me nā mea hoʻopili i hoʻohana ʻia e hoʻopaʻa i nā mea uila, e like me ke sila, sila, a me ka ipuhao. Hiki i nā mea uila i hoʻopaʻa ʻia ke pāʻani i kahi wai ʻole, ʻaʻohe haʻalulu, pale lepo, anti-corrosion, hoʻopau wela, a me ka hana huna. No laila, ʻo ka glue e hoʻopili ʻia nā hiʻohiʻona o ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa haʻahaʻa haʻahaʻa, ka ikaika Dielectric kiʻekiʻe, ka insulation maikaʻi, ka palekana o ka nohona a me ka palekana.
Loaʻa i ka epoxy resin ke kūpaʻa wela maikaʻi, ka insulation uila, ka hoʻopaʻa ʻana, nā waiwai dielectric, nā waiwai mechanical, a me ka liʻiliʻi liʻiliʻi a me ke kūpaʻa kemika. Ma hope o ka hoʻohui ʻia ʻana me nā lāʻau lapaʻau, hiki iā ia ke ʻoi aku ka maikaʻi o ka hana a me nā ʻano mea āpau e pono ai no ka hoʻopili ʻana i nā mea uila, a hoʻohana nui ʻia i nā kula e like me ka hoʻopili mea uila.
Wahi a ka ʻikepili mai ka National Bureau of Statistics, ua hoʻonui ʻia ka piʻi ʻana o ka ʻoihana hana uila uila ma 2022 e 7.6% i kēlā me kēia makahiki, a ua ʻoi aku ka nui o ka ulu ʻana i kekahi mau mea uila ma mua o 30%. Hiki ke ʻike ʻia ke ʻano o ka ulu wikiwiki ʻana o ka ʻoihana uila o Kina, ʻoi aku hoʻi i nā ʻoihana uila e nānā i mua e like me semiconductors a me 5G Ma nā kahua e like me ka naʻauao artificial a me ka Internet of Things, ua mau ka ulu ʻana o ka nui o ka mākeke. ma mua loa.
I kēia manawa, ke hoʻololi nei kekahi mau hui epoxy resin ma Kina i kā lākou hoʻolālā huahana a hoʻonui i ka māhele huahana o nā brand epoxy resin e pili ana i ka ʻoihana uila. Eia kekahi, ʻo ka hapa nui o nā ʻoihana epoxy resin i hoʻolālā ʻia e kūkulu ʻia ma Kina e nānā nui i nā hiʻohiʻona huahana uila.
ʻO ka resine epoxy ka mea nui no nā lau makani turbine
Loaʻa i ka Epoxy resin nā waiwai mechanical maikaʻi loa, kūpaʻa kemika, a me ke kūpaʻa ʻana i ka corrosion, a hiki ke hoʻohana ʻia e like me nā ʻāpana structural blade, nā mea hoʻohui, a me nā uhi hana mana makani. Hiki i ka epoxy resin ke hāʻawi i ka ikaika kiʻekiʻe, ka ʻoʻoleʻa kiʻekiʻe, a me ke kūpaʻa luhi, e hōʻoia ana i ka paʻa a me ka hilinaʻi o nā lau, me ke ʻano kākoʻo, ka iwi, a me nā ʻāpana pili o nā ʻāpana. Eia kekahi, hiki i ka epoxy resin ke hoʻomaikaʻi i ka pale ʻana o ka makani a me ka hopena o ka pale ʻana o nā lau, hoʻemi i ka haʻalulu a me ka walaʻau o nā lau, a hoʻomaikaʻi i ka hana o ka mana makani.
I ka uhi ʻana o nā ʻili turbine makani, he mea nui hoʻi ka hoʻohana ʻana i ka resin epoxy. Ma ka uhi ʻana i ka ʻili o nā lau me ka resin epoxy, hiki ke hoʻomaikaʻi ʻia ke kūpaʻa a me ka pale ʻana o UV o nā lau, a hiki ke hoʻonui ʻia ke ola lawelawe o nā lau. I ka manawa like, hiki iā ia ke hōʻemi i ke kaumaha a me ke kūpaʻa o nā lau a hoʻomaikaʻi i ka hana o ka mana makani.
No laila, pono e hoʻohana nui ʻia ka epoxy resin i nā ʻano he nui o ka ʻoihana mana makani. I kēia manawa, hoʻohana nui ʻia nā mea hoʻohui e like me ka epoxy resin, carbon fiber, a me ka polyamide e like me nā mea lau no ka hana makani makani.
Aia ka mana makani o Kina i ke kūlana alakaʻi ma ka honua, me ka ulu ʻana o ka makahiki ma mua o 48%. ʻO ka hana ʻana i nā mea hana e pili ana i ka makani ka mea hoʻoikaika nui no ka ulu wikiwiki ʻana o ka hoʻohana ʻana i ka huahana epoxy resin. Ua manaʻo ʻia ʻo ka wikiwiki o ka ʻoihana makani makani o Kina e hoʻomau i ka ulu ʻana ma mua o 30% i ka wā e hiki mai ana, a ʻo ka hoʻohana ʻana i ka resin epoxy ma Kina e hōʻike pū i kahi ulu pahū.
ʻO nā resins epoxy maʻamau a kūikawā ka mea nui i ka wā e hiki mai ana
ʻO nā māhele noi lalo o ka epoxy resin he ākea loa. ʻOiai ke alakaʻi ʻia nei e ka hoʻomohala ʻana o ka ʻoihana ikehu hou, ua ulu wikiwiki ka ʻoihana i ka pālākiō, ʻo ka hoʻomohala ʻana i ka hana maʻamau, ka ʻokoʻa, a me ka hoʻomaʻamaʻa e lilo pū kekahi o nā kuhikuhi hoʻomohala nui o ka ʻoihana.
ʻO ke kuhikuhi o ka hoʻomohala ʻana o ka epoxy resin customization e loaʻa i nā kuhikuhi noi. ʻO ka mea mua, loaʻa i ka papa kaapuni keleawe ʻole halogen ke koi no ka ʻai ʻana i ka linear phenolic epoxy resin a me Bisphenol F epoxy resin; ʻO ka lua, ʻo ke koi ʻai no ka o-methylphenol formaldehyde epoxy resin a me ka hydrogenated bisphenol Ke ulu wikiwiki nei ka resin epoxy; ʻO ke kolu, ʻo ka meaʻai epoxy resin he huahana i hoʻomaʻemaʻe hou ʻia e ka resin epoxy kuʻuna, nona kekahi mau manaʻo hoʻomohala ke hoʻohana ʻia i nā kini metala, pia, nā mea inu kalapona, a me nā kini wai hua; ʻO ka hā, ʻo ka laina hana resin multi-functional he laina hana e hiki ke hana i nā resins epoxy a me nā mea maka, e like me nā resins composite haʻahaʻa haʻahaʻa maʻemaʻe. β- Phenol type epoxy resin, liquid crystal epoxy resin, special structure low viscosity DCPD type epoxy resin, a pela aku.
Ma kekahi ʻaoʻao, ua alakaʻi ʻia e ka hoʻohana ʻana i ke kahua uila uila, a ma ka ʻaoʻao ʻē aʻe, kahi ākea o nā kahua noi a me ka puka ʻana o nā hiʻohiʻona kiʻekiʻe kiʻekiʻe i lawe mai i nā wahi hoʻohana nui i ka ʻoihana resin epoxy. Manaʻo ʻia ʻo ka hoʻohana ʻana i ka ʻoihana epoxy resin o Kina e hoʻomau i ka ulu wikiwiki o ka 10% i ka wā e hiki mai ana, a hiki ke manaʻo ʻia ka hoʻomohala ʻana o ka ʻoihana epoxy resin.
