ʻO PTFE, FEP a me PFA nā fluoroplastics kaulana loa.Akā, he aha kā lākou ʻokoʻa?E ʻike i ke kumu he mau mea ʻokoʻa nā fluoropolymers, a ʻo wai ka fluoroplastic i kūpono i kāu noi.
ʻO nā waiwai kūikawā o nā fluoroplastics
Loaʻa i nā Fluoropolymers kekahi mau waiwai kūʻokoʻa i kūpono iā lākou no ka hoʻohana ʻana i ka lāʻau lapaʻau, automotive, uila a me nā noi home, a me nā mea ʻē aʻe.
Loaʻa i nā Fluoroplastics nā waiwai penei:
1.Very kiʻekiʻe hana wela
2.Non-stick hiʻona
3.Low friction ili
4.Very kiʻekiʻe ke kū'ē i nā kinikona a me nā'ūlū
5.Very kiʻekiʻe uila kū'ē
Loaʻa nā fluoroplastics like ʻole i nā ʻokoʻa liʻiliʻi, me nā ʻano mahana hana like ʻole, a kūpono i nā noi like ʻole.Inā koho pololei ʻia, hiki i nā fluoropolymers ke hāʻawi i nā kumukūʻai maikaʻi a me nā pono hana.
ʻO nā pono o ka PTFE
PTFE, a i ole Polytetrafluoroethylene, ke kupunakane o na fluoroplastics a pau.Ua ʻike ʻia e ka mea ʻepekema ʻo Roy J. Plunkett i ka makahiki 1938, ʻo PTFE ka fluoropolymer maʻamau a hōʻike i ka hana maikaʻi loa ma ke ʻano o ka mahana, ke kūpaʻa kemika a me nā waiwai non-stick.
Ma waho aʻe o ka leʻaleʻa i nā waiwai kūʻokoʻa o nā fluoroplastics, hoʻokaʻawale ʻo PTFE iā ia iho ma o ka loaʻa ʻana o kēia mau pono:
1.Best kumu kūʻai: hana lākiō
2. Hoʻomau ka mahana hana o + 260 ° C - ʻO kēia ka mahana hana kiʻekiʻe loa no kekahi fluoroplastic
3.Resistance i ka aneane a pau kemika
4. ʻAʻole lāʻau paʻa loa (e paheʻe ka gecko i ka PTFE)
5.Translucent kala
ʻO ka hemahema nui o ka PTFE ʻaʻole ia e hoʻoheheʻe maoli i ka wā wela a no laila paʻakikī ke hana.Pono nā ʻenehana kuʻuna ʻole no ka hoʻoheheʻe ʻana, extrude a weld i kēia fluoropolymer.
Ma muli o kāna mau waiwai kūʻokoʻa, kūpono ka PTFE no nā noi i ka insulation uila a me ka pale o nā mea uila.
He mea hana oihana makou opaipu ptfe， inā he nīnau kāu, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou!
ʻO nā pōmaikaʻi o FEP
ʻO FEP, a i ʻole Fluoroethylenepropylene, ka mana hoʻoheheʻe ʻia o PTFE.Ua like loa ka FEP me ka PTFE, akā he haʻahaʻa haʻahaʻa haʻahaʻa ka wela hana o +200°C.Eia nō naʻe, hiki ke maʻalahi ka hana ʻana o FEP a hiki ke maʻalahi i ka welded a hoʻoheheʻe hou ʻia i loko o nā profile paʻakikī.
Me ka loaʻa ʻana o nā waiwai kūʻokoʻa o nā fluoroplastics, loaʻa iā FEP kēia mau pono:
1. Hiki i ka welding a me ka hana hou
2. ʻO nā mahana hana hana o -200 ° C a + 200 ° C - hiki ke maʻalahi ka FEP i nā mahana cryogenic
3.Total kū'ē i nā kemika a me UV
4.Bio-kūpono
5. kala kala
Mahalo i kēia mau pōmaikaʻi, ʻo ka FEP heat shrink he haʻahaʻa haʻahaʻa haʻahaʻa a hiki ke hoʻohaʻahaʻa ʻia ma luna o nā mea pili i ka wela me ka makaʻu ʻole i ka pōʻino.ʻO ka hopena, kūpono ka FEP no ka hoʻopili ʻana i nā ʻāpana uila a me nā mea kani.
Nā pōmaikaʻi o ka PFA
ʻO PFA, a i ʻole Perfluoralkoxy, kahi mana wela kiʻekiʻe o FEP.He mau waiwai like ko PFA me ka FEP akā hiki ke hoʻohana ʻia i nā mahana hana a hiki i +260°C oiai e koe ana melt-processable, mahalo i ka viscosity hehee haahaa ma mua o ka PTFE.
Ma kahi o ka leʻaleʻa i nā waiwai kūʻokoʻa o nā fluoropolymers, hoʻokaʻawale ʻo PFA iā ia iho ma o ka loaʻa ʻana o nā pono aʻe:
ʻO ka mahana hana mau o +260 ° C - ʻO kēia ka wela hana kiʻekiʻe loa no kēlā me kēia fluoroplastic
1.Welding a me ka hana hou ʻana i ka hiki
2.Good permeability kū'ē
3.Excellent chemical resistance, ʻoiai ma nā mahana kiʻekiʻe
4.Bio-kūpono
Loaʻa nā māka maʻemaʻe 5.High
6. Clear kala
ʻO ka hemahema nui o PFA, ʻoi aku ka maikaʻi ma mua o ka PTFE a me FEP.
He kūpono ʻo PFA no nā noi e koi ana i kahi pae maʻemaʻe kiʻekiʻe, kūpaʻa kemika maikaʻi loa a me kahi 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 pono, a me nā liner valve.
Eia maBesteflonhe poʻe loea mākou i ka hāʻawi ʻana i nā hopena fluoropolymer hou no kāu mau noi ʻenehana.E ʻike hou aku e pili ana i kā mākouNā huahana Fluoroplastic.
