Polyvinylidene fluoride orʻO ka polyvinylidene difluoride (PVDF) he semi-crystalline thermoplastic fluoropolymer.Hiki ke hoʻoheheʻe ʻia a hiki ke hana ʻia i mau ʻāpana e ka injection a me ka hoʻowili ʻana.Hoʻohui ia i ka ikaika mechanical kiʻekiʻe me ka processability maikaʻi.PVDFhoʻohana maʻamau ʻia i nā mea hana kemika e like me nā pamu, nā ʻili, nā paipu, nā paipu a me nā mea pono.ʻO kona kumu hoʻohālike kemika (C2H2F2)n.ʻO ka PVDF kahi plastik kūikawā i hoʻohana ʻia i nā noi e koi ana i ka maʻemaʻe kiʻekiʻe loa, a me ke kūʻē ʻana i nā solvents, nā waikawa a me nā hydrocarbons.He haʻahaʻa haʻahaʻa ko PVDF he 1.78 g/cm3 i ka hoʻohālikelike ʻana me nā fluoropolymers ʻē aʻe, e like me polytetrafluoroethylene.
Loaʻa ia ma ke ʻano o nā huahana piping, sheet, tubing, films, plate and insulator for premium wire.Hiki ke hoʻopili ʻia, hoʻoheheʻe ʻia a welded a hoʻohana maʻamau ʻia i ka ʻoihana kemika, semiconductor, lāʻau lapaʻau a me nā ʻoihana pale, a menā pākahi lithium-ion.Loaʻa iā ia ma ke ʻano hepili kea huʻa paʻa-cell foam, hoʻohana nui ʻia i nā noi mokulele a me ka aerospace, a ma ke ʻano he filament paʻi 3D exotic.Hiki ke hoʻohana ʻia i ka launa pū ʻana me nā huahana meaʻai, no ka mea, ʻo ia ka FDA-compliant a ʻaʻohe mea ʻawaʻawa ma lalo o kona wela degradation.
I nā makahiki i hala iho nei, ua nui ka hoihoi i hōʻike ʻia i ka polymer Polyvinylidene Fluoride (PVDF).ʻO ka hoihoi i loaʻa iā ia no ka mea e hōʻike ana i nā waiwai piezoelectric ikaika loa i hoʻohālikelike ʻia me nā polymer pāʻoihana ʻē aʻe.Hoʻohana nui ʻia ka polymer i nā noi ʻenehana kiʻekiʻe e like me nā mea hana kemika, nā uila a me nā uila, nā noi kūikawā a me ka ikehu.Akā, he aha ka mea e hana ai ʻo PVDF i kahi plastik hana kiʻekiʻe ma nā ʻāpana he nui?E heluhelu no ka ike hou aku.
ʻO PVDF (PVF2 a i ʻole Polyvinylidene fluoride a i ʻole polyvinylidene difluoride) he semi-crystalline, maʻemaʻe kiʻekiʻe thermoplastic fluoropolymer.Me nā mahana lawelawe a hiki i 150°C, hōʻike ʻo PVDF i kahi hui maikaʻi o nā waiwai e like me:
- Kūʻē kemika kūʻokoʻa
- Ka ikaika mechanical kiʻekiʻe
- Piezoelectric a me pyroelectric waiwai
- A me ka maikaʻi processability
ʻO kona makemake nui ʻole a me nā waiwai uila ka hopena mai ka polarity o nā pūʻulu CH2 a me CF2 ma ke kaulahao polymer.
Hiki ke hoʻoheheʻe ʻia ka PVDF a hiki ke hana ʻia i mau ʻāpana e ka injection a me ka hoʻoheheʻe ʻana.ʻO ka hopena, hoʻohana maʻamau ia i nā mea hana kemika e like me nā pamu, nā kiwi, nā paipu, nā paipu a me nā mea pono;nā mea ʻike a me nā mea hana etc.
Loaʻa iā ia nā noi uila he nui, ʻoi aku hoʻi e like me nā mea lole no ka plenum-rated cable i hoʻohana ʻia i nā leo a me nā polokalamu wikiō a me nā ʻōnaehana alarm.ʻO ka laha ahi haʻahaʻa a me ka hana ʻana o ka uahi o PVDF kahi waiwai nui i kēia mau noi.
Loaʻa ka PVDF i ka ʻae ʻia ma ke ʻano he mea hoʻopaʻa no nā cathodes a me nā anodes i nā pā lithium-ion, a ma ke ʻano he mea hoʻokaʻawale pākaukau i nā ʻōnaehana polimer lithium-ion.
ʻO nā noi e puka mai ana o PVDF e pili ana i nā membrane cell fuel, a me nā ʻāpana no nā mokulele mokulele a me nā lako hana ʻoihana
Mahalo i kāna hui maikaʻi loa o nā waiwai a me ka hiki ke hana, ua lilo ʻo PVDF i ka nui o nā fluoropolymers ma hope o PTFE.
Loaʻa ka PVDF ma ke kālepa ma kahi ākea o nā kahe kahe o ka hehee a me nā mea hoʻohui like ʻole e hoʻomaikaʻi i ka hana ʻana a i ʻole nā mea hoʻohana hope.
ʻO kā mākou mīkini hoʻoheheʻe ʻilika hiki ke hoʻohana i ka wili kūikawā a me ka barela e hana a hana hou i ka PVDF. ʻO ka Screw mākou e hoʻohana i ka huila C267 a hoʻohana ka pahu i ka alloy Ni.E hoʻohana ka ʻōnaehana hana hou a me ka pelletizing i kastrand pelletizing e hana i ka mea.
Me ke aloha,
