ʻO ka hā, ka noi ʻana opolyimide:
Ma muli o nā hiʻohiʻona o ka polyimide i ʻōlelo ʻia ma luna i ka hana a me ke kemika synthetic, he paʻakikī ke ʻike i ka nui o nā noi e like me ka polyimide ma waena o nā polymers he nui, a hōʻike ia i ka hana koʻikoʻi loa i kēlā me kēia ʻano..
1. Kiʻiʻoniʻoni: ʻO ia kekahi o nā huahana mua loa o ka polyimide, i hoʻohana ʻia no ka insulation slot o nā kaʻa a me nā mea wīwī no nā kaula.ʻO nā huahana nui ʻo DuPont Kapton, Ube Industries 'Upilex series a me Zhongyuan Apical.Hoʻohana ʻia nā kiʻiʻoniʻoni polyimide maʻalahi ma ke ʻano he substrates cell solar.
2. Hoʻopili: hoʻohana ʻia e like me ka insulating varnish no ka uea electromagnetic, a i ʻole hoʻohana ʻia e like me ka uhi ʻana i ka wela wela.
3. Nā mea hoʻohui kiʻekiʻe: hoʻohana ʻia i ka aerospace, nā mokulele a me nā ʻāpana rocket.ʻO ia kekahi o nā mea hoʻolālā pale wela kiʻekiʻe.No ka laʻana, ua hoʻolālā ʻia ka papahana mokulele mokulele US me ka wikiwiki o 2.4M, kahi mahana wela o 177 ° C i ka wā lele, a me ke ola lawelawe pono o 60,000h.Wahi a nā hōʻike, 50% o nā mea hana i hoʻoholo ʻia e hoʻohana i ka polyimide thermoplastic e like me ka resin matrix.ʻO ka carbon fiber i hoʻoikaika ʻia i nā mea hoʻohuihui, ʻo ka nui o kēlā me kēia mokulele ma kahi o 30t.
4. Fiber: ʻO ka modulus o ka elasticity ka lua wale nō i ke kalapona kalapona.Hoʻohana ʻia ʻo ia ma ke ʻano he kānana no ka media wela kiʻekiʻe a me nā mea radioactive, a me nā lole pale a me ke ahi.
5. Foam plastic: hoʻohana ʻia e like me ke ʻano wela wela wela.
6. ʻEnekinia plastics: Aia nā ʻano thermosetting a me thermoplastic.Hiki ke hoʻoheheʻe ʻia nā ʻano Thermoplastic a i ʻole ke hoʻoheheʻe ʻia a hoʻololi ʻia paha.Hoʻohana nui ʻia no ka lubrication ponoʻī, sealing, insulation a me nā mea hana.Ua hoʻomaka ʻia nā mea polyimide Guangcheng i nā ʻāpana mechanical e like me nā compressor rotary vanes, piston apo a me nā sila pauma kūikawā.
7. Adhesive: hoʻohana e like me ke kiʻekiʻe wela structural adhesive.Ua hana ʻia ʻo Guangcheng polyimide adhesive ma ke ʻano he kiʻekiʻe-insulation potting compound no nā mea uila.
8. Membrane hoʻokaʻawale: hoʻohanaʻia no ka hoʻokaʻawaleʻana i nā hui kinoea likeʻole, e like me ka hydrogen / nitrogen, nitrogen / oxygen, carbon dioxide / nitrogen a methane, a me nā mea'ē aʻe, e wehe i ka makū mai ka ea hydrocarbon hānai kinoea a me nā waiʻona.Hiki ke hoʻohana ʻia e like me ka membrane pervaporation a me ka membrane ultrafiltration.Ma muli o ke kūpaʻa wela a me ka pale ʻana o ka polyimide organik, he mea koʻikoʻi ia i ka hoʻokaʻawale ʻana o nā kinoea a me nā wai.
9. Photoresist: Aia nā kū'ē kū'ē a maikaʻi, a hiki i ka hoʻonā ke piʻi i ka pae submicron.Hiki ke hoʻohana ʻia i loko o ke kiʻi kānana kala i hui pū ʻia me nā puaʻa a i ʻole nā kala, hiki ke maʻalahi i ke kaʻina hana.
10. Hoʻohana i nā mea microelectronic: ma ke ʻano he papa dielectric no ka insulation interlayer, ma ke ʻano he pale pale e hōʻemi i ke kaumaha a hoʻomaikaʻi i ka hua.Ma keʻano he pale pale, hiki iā ia ke hoʻemi i ka mana o ke kaiapuni ma luna o ka mea hana, a hiki ke pale aku i nā a-particles, e hōʻemi a hoʻopau paha i ka hewa palupalu (softerror) o ka mea.
11. Mea hoʻoponopono no ka hōʻike aniani wai:PolyimideHe hana koʻikoʻi loa ia i ka mea alignment agent o TN-LCD, SHN-LCD, TFT-CD a me ka hōʻike aniani wai ferroelectric e hiki mai ana.
12. Electro-optic mea: hoʻohana 'ia ma ke 'ano he passive a i 'ole nā mea hana hawewe nalu, optical switch materials, etc. Fluorine-containing polyimide is transparent in the communication wavelength range, and using polyimide as a chromophore matrix can improve the performance of the material.kūpaʻa.
I ka hōʻuluʻulu ʻana, ʻaʻole paʻakikī ke ʻike i ke kumu e hiki ai i ka polyimide ke kū i waho o nā polymers heterocyclic aromatic i ʻike ʻia i nā makahiki 1960 a me 1970, a lilo i papa nui o nā mea polymer.
5. Nānā:
Ma ke ʻano he mea polymer hoʻohiki,polyimideua ʻike piha ʻia, a ke hoʻonui mau nei kāna noi ʻana i nā mea insulating a me nā mea hana.Ma ke ʻano o nā mea hana, ke puka mai nei, a ke ʻimi ʻia nei kona hiki.Eia naʻe, ma hope o 40 mau makahiki o ka hoʻomohala ʻana, ʻaʻole ia i lilo i ʻano nui.ʻO ke kumu nui ke kiʻekiʻe loa ke kumukūʻai i hoʻohālikelike ʻia me nā polymers ʻē aʻe.No laila, ʻo kekahi o nā kuhikuhi nui o ka noiʻi polyimide i ka wā e hiki mai ana, ʻo ia ka ʻimi ʻana i nā ala e hōʻemi ai i nā kumukūʻai i ka monomer synthesis a me nā ʻano polymerization.
1. Hoʻohui ʻia o nā monomers: ʻO nā monomers o polyimide he dianhydride (tetraacid) a me diamine.ʻO ke ʻano hana synthesis o ka diamine he ʻano makua, a he nui nā diamine i loaʻa i ke kālepa.ʻO Dianhydride kahi monomer kūikawā, i hoʻohana nui ʻia i ka synthesis o polyimide koe wale nō ka mea hoʻōla o ka resin epoxy.Hiki ke loaʻa ka Pyromellitic dianhydride a me ka trimellitic anhydride e ka pae kinoea hoʻokahi-ʻanuʻu a me ka hoʻoheheʻe ʻana o ka wai o ka durene a me ka trimethylene i unuhi ʻia mai ka aila ʻala kaumaha, kahi huahana o ka hoʻomaʻemaʻe ʻaila.ʻO nā dianhydride koʻikoʻi ʻē aʻe, e like me benzophenone dianhydride, biphenyl dianhydride, diphenyl ether dianhydride, hexafluorodianhydride, a me nā mea ʻē aʻe, ua hana ʻia e nā ʻano ʻano like ʻole, akā nui ke kumukūʻai.umi tausani yuan.Hoʻomohala ʻia e Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, kiʻekiʻe-maʻemaʻe 4-chlorophthalic anhydride a me 3-chlorophthalic anhydride hiki ke loaʻa mai ka o-xylene chlorination, oxidation a me isomerization separation.ʻO ka hoʻohana ʻana i kēia mau pūhui ʻelua e like me nā mea maka hiki ke synthesize i kahi Series dianhydrides, me ka hiki ke hōʻemi i ke kumu kūʻai, he ala synthetic waiwai.
2. Ke kaʻina hana polymerization: ʻO ke kaʻina hana ʻelua-ʻanuʻu i hoʻohana ʻia i kēia manawa a me kahi kaʻina polycondensation hoʻokahi-ʻanuʻu e hoʻohana i nā mea hoʻoheheʻe kiʻekiʻe.He kiʻekiʻe ke kumukūʻai o nā solvents polar aprotic, a paʻakikī ke wehe iā lākou.ʻO ka hope, koi ʻia ka mālama wela kiʻekiʻe.Hoʻohana ke ʻano PMR i kahi mea hoʻoheheʻe waiʻona liʻiliʻi.Hiki i ka Thermoplastic polyimide ke polymerized a me ka granulated pololei i ka extruder me ka dianhydride a me ka diamine, ʻaʻohe mea e pono ai, a hiki ke hoʻomaikaʻi maikaʻi ʻia ka pono.ʻO ia ke ala synthesis ʻoi loa e loaʻa ai ka polyimide ma o ka polymerizing chlorophthalic anhydride me ka diamine, bisphenol, sodium sulfide a i ʻole elemental sulfur me ka hele ʻole o ka dianhydride.
3. Hoʻoponopono: ʻO ka hoʻohana ʻana o ka polyimide he ākea loa, a aia nā koi like ʻole no ka hana ʻana, e like me ke kūlike kiʻekiʻe o ka hoʻokumu ʻana i ke kiʻiʻoniʻoni, wili, deposition mahu, sub-micron photolithography, hohonu pololei paia engraving Etching, nui-wahi, nui- ʻO ka hoʻoheheʻe ʻana i ka volume, ka hoʻokomo ʻana i ka ion, ka hoʻoponopono pololei ʻana i ka laser, ka ʻenehana hybrid nano-scale, etc.
Me ka hoʻomaikaʻi hou ʻana o ka ʻenehana hana o ka ʻenehana synthesis a me ka hoʻohaʻahaʻa nui ʻana o ke kumukūʻai, a me kāna mau waiwai mechanical kiʻekiʻe a me nā waiwai insulation uila, ʻoi aku ka nui o ka polyimide thermoplastic i ke kahua o nā mea i ka wā e hiki mai ana.A ʻoi aku ka maikaʻi o ka polyimide thermoplastic ma muli o kāna hana maikaʻi.
6. Ka hopena:
Nui nā kumu nui no ka hoʻomohala lohi opolyimide:
1. Ka hoʻomākaukauʻana i nā mea waiwai no ka hana polyimide:ʻaʻole lawa ka maʻemaʻe o ka pyromellitic dianhydride.
2. ʻO ka mea maka o ka pyromellitic dianhydride, ʻo ia hoʻi, ua kaupalena ʻia ka puka o ka durene.Hoʻopuka honua: 60,000 tons / makahiki, puka home: 5,000 tons / makahiki.
3. He kiʻekiʻe loa ke kumukūʻai hana o pyromellitic dianhydride.I ka honua, ma kahi o 1.2-1.4 tons durene e hoʻopuka i 1 ton o pyromellitic dianhydride, aʻo nā mea hana maikaʻi loa ma koʻu ʻāina i kēia manawa e hana i kahi 2.0-2.25 tons durene.nā tona, ʻo Changshu Federal Chemical Co., Ltd. wale nō i hiki i ka 1.6 tons/ton.
4. He liʻiliʻi loa ka pālākiō hana o ka polyimide e hana i kahi ʻoihana, a he nui a paʻakikī nā hopena ʻaoʻao o ka polyimide.
5. ʻO ka hapa nui o nā ʻoihana kūloko i ka ʻike koi kuʻuna, e kaupalena ana i ka wahi noi i kekahi ʻano.Hoʻohana mua lākou i nā huahana haole a ʻike paha i nā huahana haole ma mua o ka ʻimi ʻana iā lākou ma Kina.Loaʻa nā pono o kēlā me kēia ʻoihana mai nā pono o nā mea kūʻai aku o lalo o ka ʻoihana, ka ʻike manaʻo a me ka ʻike;ʻAʻole maʻalahi nā ala kumu, nui nā loulou waena, a ʻaʻole i kūpono ka nui o ka ʻike pololei.
