ʻO PTFE, FEP a me PFA nā fluoroplastics i ʻike nui ʻia a maʻamau. Akā he aha ko lākou ʻokoʻa? E ʻike i ke kumu he mea kūikawā nā fluoropolymers, a ʻo wai ka fluoroplastic i kūpono loa i kāu noi.
Nā waiwai kūikawā o nā fluoroplastics
Loaʻa i nā Fluoropolymers kekahi mau waiwai kū hoʻokahi e kūpono ai no ka hoʻohana ʻana i nā lāʻau lapaʻau, kaʻa, nā uila a me nā noi kūloko, a me nā mea ʻē aʻe.
Loaʻa i nā fluoroplastics nā waiwai penei:
1. Nā mahana hana kiʻekiʻe loa
2. ʻAno ʻaʻole e pipili
3. ʻIli haʻahaʻa haʻahaʻa
4. Kū'ē kiʻekiʻe loa i nā kemika a me nā mea hoʻoheheʻe
5. Ke kū'ē uila kiʻekiʻe loa
Loaʻa i nā fluoroplastics like ʻole nā ʻokoʻa liʻiliʻi, me nā mahana hana like ʻole, a kūpono no nā noi like ʻole. Inā koho pololei ʻia, hiki i nā fluoropolymers ke hāʻawi i nā pono kumukūʻai maikaʻi a me ka hana.
Nā pono o ka PTFE
PTFE, a i ʻole Polytetrafluoroethylene, ʻo ia ke kupuna kāne o nā fluoroplastics āpau. Ua ʻike ʻia e ka ʻepekema ʻo Roy J. Plunkett i ka makahiki 1938, ʻo PTFE ka fluoropolymer ʻokoʻa loa a hōʻike i ka hana maikaʻi loa ma ke ʻano o ka mahana, ke kūpaʻa kemika a me nā waiwai ʻaʻole e pipili.
Ma waho aʻe o ka hauʻoli ʻana i nā waiwai kūikawā o nā fluoroplastics, hoʻokaʻawale ʻo PTFE iā ia iho ma o ka loaʻa ʻana o nā pono penei:
1. ʻO ke kumukūʻai maikaʻi loa: ka lakio hana
2. Ka mahana hana mau o +260°C - ʻO kēia ka mahana hana kiʻekiʻe loa no kekahi fluoroplastic
3. Ke kū'ē nei i nā kemika āpau
4. ʻAʻole e pipili loa (ʻoiai he gecko e paheʻe ma ka PTFE)
5. Waihoʻoluʻu ʻālohilohi
ʻO ka hemahema nui o ka PTFE, ʻaʻole ia e heheʻe maoli i ka wā e hoʻomehana ʻia ai a no laila he paʻakikī ke hana. Pono nā ʻano hana maʻamau ʻole e hoʻoheheʻe, hoʻopuka a hoʻoheheʻe i kēia fluoropolymer.
Ma muli o kona mau waiwai kūikawā, kūpono ʻo PTFE no nā noi i ka insulation uila a me ka pale ʻana i nā ʻāpana uila.
He mea hana ʻoihana mākou opaipu ptfe，Inā he mau nīnau kāu, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou!
Nā pono o FEP
ʻO FEP, a i ʻole Fluoroethylenepropylene, ka mana hiki ke hoʻoheheʻe ʻia o ka PTFE. He like loa nā waiwai o FEP me PTFE, akā he haʻahaʻa loa ka mahana hana kiʻekiʻe o +200°C. Eia nō naʻe, hiki ke maʻalahi ka hana ʻana o FEP a hiki ke maʻalahi ke hoʻopaʻa ʻia a hoʻoheheʻe hou ʻia i loko o nā ʻaoʻao paʻakikī.
Ma waho aʻe o ka loaʻa ʻana o nā waiwai kūikawā o nā fluoroplastics, hauʻoli ʻo FEP i kēia mau pono:
1. Ka hiki ke hoʻoheheʻe ʻia a me ke kūkulu hou ʻana
2. Nā mahana hana hana o -200°C a i +200°C - Noho maʻalahi ʻo FEP i nā mahana cryogenic
3.Total ke kūpaʻa i nā kemika a me UV
4. Kūlike me ka Bio
5. Waihoʻoluʻu moakāka
Mahalo i kēia mau pono, he haʻahaʻa ka mahana hoʻēmi wela o ka FEP a hiki ke hoʻēmi palekana ʻia ma luna o nā mea i ʻike ʻia ka mahana me ka makaʻu ʻole i ka hōʻino ʻana. ʻO ka hopena, kūpono ka FEP no ka hoʻopuni ʻana i nā ʻāpana uila a me nā mea hana.
Nā pono o ka PFA
ʻO PFA, a i ʻole Perfluoralkoxy, kahi mana wela kiʻekiʻe o FEP. Loaʻa i ka PFA nā waiwai like me FEP akā hiki ke hoʻohana ʻia i nā mahana hana a hiki i +260°C ʻoiai e hiki ke hoʻoheheʻe ʻia, mahalo i ka mānoanoa hoʻoheheʻe haʻahaʻa ma mua o PTFE.
Ma waho aʻe o ka hauʻoli ʻana i nā waiwai kūikawā o nā fluoropolymers, hoʻokaʻawale ʻo PFA iā ia iho ma o ka loaʻa ʻana o nā pono penei:
Mahana hana mau o +260°C - ʻO kēia ka mahana hana kiʻekiʻe loa no kekahi fluoroplastic
1. Ka hiki ke hoʻopili a me ke kūkulu hou ʻana
2. Ke kū'ē maikaʻi o ka permeability
3. Ke kūpaʻa kemika maikaʻi loa, ʻoiai ma nā mahana kiʻekiʻe
4. Kūlike me ka Bio
5. Loaʻa nā māka maʻemaʻe kiʻekiʻe
6. Kala moakaka
ʻO ka hemahema nui o ka PFA, ʻoi aku ke kumukūʻai ma mua o ka PTFE a me ka FEP.
He kūpono ka PFA no nā noi e pono ai kahi papa maʻemaʻe kiʻekiʻe, ke kūpaʻa kemika maikaʻi loa a me ka mahana hana kiʻekiʻe. Hoʻohana nui ʻia kēia fluoroplastic i nā paipu lapaʻau, nā mea hoʻololi wela, nā hīnaʻi semi-conductor, nā pamu a me nā mea hoʻopili, a me nā liner valve.
Maanei maʻO Besteflonhe poʻe loea mākou i ka hāʻawi ʻana i nā hopena fluoropolymer hou no kāu mau noi loea. E ʻike hou aʻe e pili ana i kā mākouNā Huahana Fluoroplastic.
