PTFE vs FEP vs PFA: He aha ka ʻokoʻa?

PTFE vs FEP vs PFA

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, he haʻahaʻa haʻahaʻa ka wela o ka FEP heat shrink a hiki ke hoʻohaʻahaʻa pono ʻia ma luna o nā mea 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.
