Nā ʻenehana hana a me nā noi Fluoropolymers

Hoʻokumu ʻia nā fluoropolymers pāʻoihana ma TFE, VDF, a ma kahi liʻiliʻi CTFE.ʻO nā laʻana o nā comonomers me PMVE, PEVE, PPVE, HFP, CTFE, a me PFBE.ʻO nā hopena maʻamau o ka hoʻololi ʻana i ka fluorine no ka hydrogen i loko o ka polymer, ʻo ia ka piʻi ʻana o ke kemika a me ka pale pale, hoʻonui ʻia nā waiwai uila e like me ka haʻahaʻa dielectric mau, haʻahaʻa haʻahaʻa o ka friction, kiʻekiʻe o ka heheʻe ʻana, hoʻonui i ka photostability a me ke kūpaʻa wela, hoʻomaikaʻi i ke kūpaʻa ahi, a nāwaliwali ka mīkini. waiwai.Loaʻa nā waiwai hope loa i ka wā e hoʻopiha piha ʻia ka polymer.

Nā ʻenehana hana

Me ka ʻelua o nā fluoropolymers, PVF a me PTFE, hiki ke hana ʻia ke koena o nā resins i wehewehe ʻia ma kēia mokuna e nā ʻenehana hoʻoheheʻe maʻamau e like me ka injection, transfer and blow molding, extrusion and rotational molding.Pono e hana ʻia nā mea hana hana no nā fluoropolymers mai nā mea hoʻoheheʻe kūʻokoʻa ma muli o ka pūhui corrosive i hiki ke hana ʻia ke hoʻomehana ʻia nā fluoropolymers ma luna o ko lākou mau wahi heheʻe.ʻOi aku ka nui o ka hoʻoheheʻe viscosity o kēia mau resins e koi hou aku i ka pauda a me nā lako helu kiʻekiʻe.

Hoʻohana ʻia ka PTFE me ka hoʻohana ʻana i nā ʻenehana hoʻoheheʻe ʻia i ka pauka metala kahi i hoʻoheheʻe ʻia a "sintered."Hiki ke hoʻohana ʻia ka hoʻoheheʻe ʻana e hana i nā ʻāpana PTFE.Hoʻopili ʻia nā dispersion PTFE e nā ʻenehana like me nā uhi ʻē aʻe.Hoʻopili ʻia ka extrusion kahi i hui ʻia ai ka PTFE me kahi hydrocarbon, ma mua o ka hoʻoheheʻe ʻana i kahi preform, hoʻohana ʻia e hana mau i ka PTFE i loko o nā paipu, nā lipine, a me ka insulation uea.Hoʻopau ʻia ka hydrocarbon ma mua o ka hoʻopaʻa ʻia ʻana o ka ʻāpana.

Hoʻopuehu ʻia ka PVF i loko o kahi mea hoʻoheheʻe polar latent e like me ka dimethyl acetamide a hoʻoheheʻe ʻia e like me ka plastisol, a ukali ʻia e ka wehe ʻana i ka solvent ma ka maloʻo.

Nā noi

ʻO nā waiwai o nā fluoropolymers i alakaʻi i nā noi e pili ana i ke kūpaʻa kemika, ke kūpaʻa wela, nā waiwai cryogenic, ka coefficient haʻahaʻa o ka friction, ka ikehu haʻahaʻa haʻahaʻa, ka hoʻomau dielectric haʻahaʻa, ka leo kiʻekiʻe a me ka resistivity i luna, a me ke kūpaʻa ahi.Hoʻohana ʻia nā Fluoropolymers ma ke ʻano he liner (papa hana) ma muli o ko lākou kūʻē ʻana i ka hoʻouka kemika.Hāʻawi lākou i nā mea ʻokoʻa paʻa, haʻahaʻa haʻahaʻa, a me ka hoʻokele waiwai i nā metala exotic no ka hoʻohana ʻana i nā wela kiʻekiʻe me ka hoʻokomo ʻole ʻana i nā haumia.ʻO nā waiwai uila ka waiwai nui o nā fluoropolymers i nā polokalamu uila a me nā uila e like me nā insulators, e laʻa, FEP i nā kamaʻilio ʻikepili.

I nā kaʻa kaʻa a me nā lako keʻena, pono nā waiwai mechanical o nā fluoropolymers i nā bearings haʻahaʻa haʻahaʻa a me nā sila e kūʻē i ka hoʻouka ʻana e nā hydrocarbons a me nā wai ʻē aʻe.I ka hoʻoili ʻana i ka meaʻai, ua ʻae ʻia nā māka fluoropolymer i ka meaʻai a me ka lāʻau lapaʻau no nā lako hana ma muli o ko lākou kūʻē ʻana i ka aila a me nā mea hoʻomaʻemaʻe, a me kā lākou mau mea anti-stick a me nā waiwai friction haʻahaʻa.I loko o nā lako hale, hoʻohana ʻia nā fluoropolymers ma ke ʻano he pale nonstick no nā mea kuke a me nā mea hana.ʻO nā ʻatikala lapaʻau e like me nā ʻokiʻoki a me nā grafts cardiovascular e hilinaʻi i ka paʻa lōʻihi o nā fluoropolymers a me ko lākou ikaika haʻahaʻa a me ke kūpaʻa kemika.

No nā mokulele, nā kahua pāʻani, a me nā hale ʻē aʻe, ua hana ʻia ka lole fiber aniani i uhi ʻia me PTFE i ka hale a me nā pā.Hāʻawi ʻo PTFE i ke kūpaʻa maikaʻi loa i ka wā, me ka ʻike ʻana i nā kukuna UV i ka lā, ka pale ʻana i ke ahi no ka palekana, a me ka ikehu haʻahaʻa no ka pale ʻana i ka lepo, a me ka hoʻomaʻemaʻe maʻalahi.
