I ka ʻoihana mana makani, ua hoʻohana nui ʻia ka epoxy resin i nā mea makani turbine blade.ʻO ka epoxy resin kahi mea hana kiʻekiʻe me nā waiwai mechanical maikaʻi loa, kūpaʻa kemika, a me ka pale ʻana i ka corrosion.I ka hana ʻana i nā ʻāpana turbine makani, hoʻohana nui ʻia ka epoxy resin i nā ʻāpana hana, nā mea hoʻohui, a me nā uhi o nā lau.Hiki i ka epoxy resin ke hāʻawi i ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, a me ke kūpaʻa luhi i ke kākoʻo kākoʻo, iwi iwi, a me nā ʻāpana hoʻohui o ka lau, e hōʻoia ana i ka paʻa a me ka hilinaʻi o ka lau.

Hiki i ka Epoxy resin ke hoʻomaikaʻi i ka ʻili makani a me ka hopena o ka pale ʻana o nā lau, e hōʻemi i ka leo haʻalulu o ka ʻili, a hoʻomaikaʻi i ka hana ʻana o ka makani.I kēia manawa, hoʻohana pololei ʻia ka epoxy resin a me ke aniani fiber i hoʻololi ʻia i ka makani turbine blade material, hiki ke hoʻomaikaʻi i ka ikaika a me ka pale ʻana i ka corrosion.

I nā mea hoʻoheheʻe makani turbine, pono ka hoʻohana ʻana i ka epoxy resin i ka hoʻohana ʻana i nā huahana kemika e like me ka curing agents a me nā accelerators:

ʻO ka mea mua, ʻo ka mea maʻamau epoxy resin curing agent i ka ʻoihana mana makani he polyether amine

ʻO kahi huahana maʻamau he polyether amine, ʻo ia hoʻi ka mea hoʻohana maʻamau epoxy resin curing agent i ka ʻoihana makani.Hoʻohana ʻia ka polyether amine epoxy resin curing agent i ka hoʻōla ʻana o ka matrix epoxy resin a me ka hoʻopili ʻana.Loaʻa iā ia nā waiwai piha maikaʻi e like me ka haʻahaʻa haʻahaʻa, ka lōʻihi o ka lawelawe ʻana, anti-aging, etc. Ua hoʻohana nui ʻia i ka hana makani makani, ka paʻi textile a me ke kala ʻana, ke kaʻaahi anti-corrosion, ke alahaka a me ka wai ʻole o ka moku, ka ʻimi ʻaila a me ka shale kinoea. a me nā kula ʻē aʻe.ʻO ka lalo o ka polyether amine e ʻoi aku ma mua o 62% o ka mana makani.Pono e hoʻomaopopo ʻia aia nā amine polyether i nā resins amine epoxy.

Wahi a ka hoʻokolokolo ʻana, hiki ke loaʻa nā amine polyether ma o ka hoʻohui ʻana o ka polyethylene glycol, polypropylene glycol, a i ʻole ethylene glycol/propylene glycol copolymers ma lalo o ke kiʻekiʻe o ka wela a me ke kaomi.Ke koho ʻana i nā hale polyoxoalkyl ʻokoʻa hiki ke hoʻoponopono i ka hana pane, ka paʻakikī, ka viscosity, a me ka hydrophilicity o polyether amines.ʻO ka polyether amine nā mea maikaʻi o ka paʻa maikaʻi, ka liʻiliʻi o ka keʻokeʻo, ka nani maikaʻi ma hope o ka hoʻōla ʻana, a me ka paʻakikī kiʻekiʻe.Hiki iā ia ke hoʻoheheʻe i nā mea hoʻoheheʻe e like me ka wai, ethanol, hydrocarbons, esters, ethylene glycol ethers, a me nā ketones.

Wahi a ka noiʻi, ua ʻoi aku ka nui o ka hoʻohana ʻana o ka mākeke amine polyether Kina ma mua o 100000 tons, e hōʻike ana i ka piʻi ʻana o 25% i nā makahiki i hala.Ua manaʻo ʻia e 2025, ʻoi aku ka nui o ka mākeke o nā polyether amines ma Kina ma mua o 150000 tons i ka wā pōkole, a ke manaʻo ʻia nei ka ulu ʻana o ka nui o ka polyether amines ma kahi o 8% i ka wā e hiki mai ana.

ʻO ka ʻoihana hana o polyether amine ma Kina ʻo Chenhua Co., Ltd., nona nā kumu hana ʻelua ma Yangzhou a me Huaiʻan.Loaʻa iā ia he 31000 tons / makahiki o ka polyether amine (end amino polyether) (me ka mana hoʻolālā o 3000 tons / makahiki o ka polyether amine project ma lalo o ke kūkulu ʻia ʻana), 35000 tons / makahiki o alkyl glycosides, 34800 tons / makahiki o ke ahi retardants. , 8500 tons / makahiki o ka silicone rubber, 45400 tons / makahiki o polyether, 4600 tons / makahiki o ka aila silicone, a me nā mana hana ʻē aʻe o 100 tons / makahiki.Hoʻolālā ka Future Changhua Group e hoʻolilo ma kahi o 600 miliona yuan ma ka Huaiʻan Industrial Park ma Jiangsu Province e kūkulu i kahi hana makahiki o 40000 tons of polyether amine a me 42000 tons of polyether projects.

Eia kekahi, ʻo Wuxi Acoli, Yantai Minsheng, Shandong Zhengda, ʻenehana Real Madrid a me Wanhua Chemical nā ʻoihana ʻoihana polyether amine ma Kina.Wahi a nā helu helu o nā papahana i hoʻolālā ʻia ma lalo o ke kūkulu ʻana, ʻoi aku ka lōʻihi o ka hoʻolālā ʻana o ka polyether amines ma Kina ma mua o 200000 tons i ka wā e hiki mai ana.Ua manaʻo ʻia e ʻoi aku ka lōʻihi o ka hana ʻana o nā polyether amines ma Kina ma mua o 300000 tons i kēlā me kēia makahiki, a e hoʻomau ʻia ka ulu ulu lōʻihi.

ʻO ka lua, ʻo ka mea hoʻōla epoxy resin e ulu wikiwiki ana i ka ʻoihana mana makani: methyltetrahydrophthalic anhydride.

Wahi a ka noiʻi, ʻo ka mea hoʻōla epoxy resin epoxy wikiwiki loa i ka ʻoihana mana makani he methyltetrahydrophthalic anhydride curing agent.Ma ke kahua o ka makani mana epoxy curing agents, aia kekahi methyl tetrahydrophthalic anhydride (MTHPA), ʻo ia ka mea lapaʻau maʻamau i hoʻohana pinepine ʻia i ka hana kiʻekiʻe epoxy resin e pili ana i ka carbon fiber (a i ʻole aniani fiber) i hoʻoikaika ʻia i nā mea hoʻohui no ka makani mana ma o. kaʻina hana hoʻoheheʻe extrusion.Hoʻohana pū ʻia ka MTHPA i nā mea ʻike uila, nā lāʻau lapaʻau, nā pesticides, resins, a me nā ʻoihana pale aupuni.ʻO ka Methyl tetrahydrophthalic anhydride he mea koʻikoʻi o ka anhydride curing agents a me ka wikiwiki o ka ulu ʻana o ka lāʻau lapaʻau i ka wā e hiki mai ana.

Hoʻopili ʻia ʻo Methyltetrahydrophthalic anhydride mai maleic anhydride a me methylbutadiene ma o ka diene synthesis a laila isomerized.ʻO Puyang Huicheng Electronic Materials Co., Ltd., ʻo ka ʻoihana kūloko nui, me ka nui o ka hoʻohana ʻana ma kahi o hoʻokahi kaukani tona ma Kina.Me ka ulu wikiwiki ʻana o ka hoʻokele waiwai a me ka hoʻonui ʻana i ka hoʻonui ʻana, ke hoʻomau nei ka noi no nā uhi, plastics, a me ka rubber, e hoʻonui ana i ka ulu ʻana o ka mākeke methyl tetrahydrophthalic anhydride.

Eia kekahi, ua komo pū nā mea ho'ōla anhydride i ka tetrahydrophthalic anhydride THPA, hexahydrophthalic anhydride HHPA, methylhexahydrophthalic anhydride MHHPA, methyl-p-nitroaniline MNA, etc. Hiki ke hoʻohana ʻia kēia mau huahana ma ke kahua o ka makani turbine blade epoxy resin curing agents.

ʻO ke kolu, ʻo ka epoxy resin curing agents me ka hana maikaʻi loa i ka ʻoihana mana makani e komo pū me isophorone diamine a me methylcyclohexane diamine.

Ma waena o nā huahana epoxy resin curing agent, ʻo nā ʻano lāʻau lapaʻau kiʻekiʻe loa ka isoflurone diamine, methylcyclohexanediamine, methyltetrahydrophthalic anhydride, tetrahydrophthalic anhydride, hexahydrophthalic anhydride, methylhexahydrophthalic anhydride, methyl-p-nitroaniline ikaika, etc. ʻO ka manawa hana kūpono, ka hoʻokuʻu wela haʻahaʻa haʻahaʻa, a me ke kaʻina hana injection maikaʻi loa, a hoʻohana ʻia i loko o nā mea hana o ka epoxy resin a me ke aniani aniani no nā ʻōpala turbine makani.ʻO nā mea hoʻolaʻa anhydride no ka hoʻōla wela a ʻoi aku ka maikaʻi no ke kaʻina hana hoʻoheheʻe extrusion o nā lau turbine makani.

ʻO nā ʻoihana hana honua o isophorone diamine ka BASF AG ma Kelemānia, Evonik Industries, DuPont ma United States, BP ma UK, a me Sumitomo ma Iapana.Ma waena o lākou, ʻo Evonik ka ʻoihana hana isophorone diamine nui loa ma ka honua.ʻO nā ʻoihana Kina nui ʻo Evonik Shanghai, Wanhua Chemical, Tongling Hengxing Chemical, a me nā mea ʻē aʻe, me ka nui o ka hoʻohana ʻana ma kahi o 100000 tons ma Kina.

ʻO ka Methylcyclohexanediamine ka mea maʻamau ka hui ʻana o 1-methyl-2,4-cyclohexanediamine a me 1-methyl-2,6-cyclohexanediamine.He aliphatic cycloalkyl pūhui i loaʻa ma ka hydrogenation o 2.4-diaminotoluene.Hiki ke hoʻohana wale ʻia ka Methylcyclohexanediamine ma ke ʻano he lāʻau lapaʻau no ka epoxy resins, a hiki ke hui pū ʻia me nā mea hoʻolaʻa epoxy maʻamau (e like me fatty amines, alicyclic amines, aromatic amines, acid anhydrides, etc.) , imidazole).ʻO nā mea hana nui o ka methylcyclohexane diamine ma Kina, ʻo ia ʻo Henan Leibairui New Material Technology Co., Ltd. a me Jiangsu Weiketerri Chemical Co., Ltd. ʻO ka nui o ka hoʻohana ʻana ma kahi o 7000 tons.

Pono e hoʻomaopopo ʻia ʻaʻole e like me ka hoʻōla ʻana o ka amine i ka honua a ʻoi aku ka lōʻihi o ke ola e like me ka anhydride curing agents, akā ʻoi aku ka maikaʻi o ka hana a me ka manawa hana i hoʻohālikelike ʻia me nā ʻano mea hoʻolaʻa anhydride.

He nui nā ʻano huahana epoxy resin curing agent ʻo Kina i ka ʻoihana mana makani, akā hoʻokahi nā huahana nui i hoʻohana ʻia.Ke ʻimi nei ka mākeke honua a me ka hoʻomohala ʻana i nā huahana epoxy resin curing agent hou, a ke hoʻomaikaʻi mau nei nā huahana curing agent.He lohi ka holomua o ia mau huahana ma ka mākeke Kina, ma muli o ke kumukūʻai kiʻekiʻe o ka hoʻololi ʻana i ka formula no nā huahana epoxy resin curing agent i ka ʻoihana makani makani, a me ka nele o nā huahana piha.Eia nō naʻe, me ka hoʻomau mau ʻana o ka ʻenehana a me ka hoʻohui ʻana o ka epoxy resin curing agents me ka mākeke honua, ʻo nā huahana epoxy resin curing agent o Kina i ka pā makani makani e hoʻomau mau ʻia a me nā hoʻololi.
