Mai ka hoʻomaka ʻana o Dupont e hana i ka PTFE i ka makahiki 1945, he 61 mau makahiki mai ia manawa.I kēia manawa he huahana koʻikoʻi o PTFEPTFE microporous kiʻiʻoniʻonihoʻohana nui ʻia, e hoʻonui ana i ke kahua mai ka ʻenekinia biological a hiki i ka ʻoihana lole, mai ka ʻoihana mechanical a hiki i ka petrochemical, i ka ʻoihana mālama kaiapuni hiki ke hoʻohana ʻia ʻaʻole wale no nā papahana mālama wai, akā no ka hoʻomaʻemaʻe ʻana i ka ea.Hiki ke ʻōlelo ʻia ʻo ia ka laulā o kāna noi.
Nā hiʻohiʻona o ka polytetrafluoroethylene
1. Nā hiʻohiʻona o ka hale molekala
2. Paʻa kemika
3. Nā waiwai wela

Ka hoʻomohala ʻana o ka kiʻiʻoniʻoni microporous PTFE
I kēia manawa, ke kaʻina hana oPTFE microporous kiʻiʻoniʻoniloaʻa ke ʻano kiʻiʻoniʻoni calendering, ke ʻano kiʻiʻoniʻoni hoʻohuli a me ke ʻano kiʻiʻoniʻoni kikoo.Hiki ke hoʻokaʻawale ʻia ke ʻano kiʻi ʻoniʻoni i hoʻokahi ala a me ʻelua ala, ma o ka nānā ʻana i ka hana a me ke ana maoli ʻana, ʻelua wale ke kiʻi ʻoniʻoni i loaʻa ka microporous maikaʻi.Hōʻike ʻia ke kaʻina hana o ka biaxially oriented PTFE microporous kiʻi ma ke kiʻi.
Noi o PTFE microporous kiʻiʻoniʻoni
1. Hoʻohana i nā mea kānana
2. Hoʻohana i nā mea lapaʻau
Hoʻomākaukau ʻana i ke kiʻiʻoniʻoni PTFE
1. Ka hana mua o ka PTFE microporous kiʻiʻoniʻoni
2. Kaʻina hoʻomākaukau
3. Kaʻina hana
Ka hopena o nā ʻāpana hana i nā waiwai o nā kiʻiʻoniʻoni PTFE
ʻO nā mea e hoʻopili ai i nā waiwai o nā kiʻi ʻoniʻoni microporous PTFE i ka biaxial stretching process a me kāna hana mua he paʻakikī a multifaceted.Ma waho aʻe o ka hana ʻana o nā mea hana, ka hoʻolōʻihi ʻana i ka mahana a me ka wikiwiki o ka hoʻolōʻihi ʻana, ʻo nā mea hoʻohālikelike ʻē aʻe: ka mahana hana, ka haʻahaʻa hana.
ʻO ka mahana hana: ʻO nā kiʻiʻoniʻoni PTFE ka mea maʻalahi i ka wela, a hiki i nā wela hana like ʻole ke hopena i nā waiwai kiʻiʻoniʻoni like ʻole.ʻO ka mahana he mea koʻikoʻi hana koʻikoʻi ʻaʻole wale i ke kaʻina hoʻolōʻihi, akā i ka hana ʻana o ka resin PTFE a me nā kaʻina waena.
ʻO ka haʻahaʻa hana: ʻO ka haʻahaʻa e pili ana i ka mahana a ʻaʻole hiki ke kūkākūkā me ka ʻole o ka mahana.He hopena hoʻi ka haʻahaʻa ambient i ke kiʻiʻoniʻoni.
Loaʻa i ka PTFE ke kūpaʻa kemika koʻikoʻi, ka hana kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa a me ka pale ʻana i ka corrosion, a hoʻohana nui ʻia i nā kemika, petroleum, textile, uila a me nā ʻoihana mechanical.I kēia manawa, ʻo ka ikaika hydrophobic a me nā waiwai porous o PTFE e lilo ia i mea membrane kūpono no ka hoʻomākaukau ʻana i nā fibers wai a me nā breathable textile a me ka distillation membrane a me nā contactors membrane.Ke hoʻohālikelike ʻia me nā mea membrane ʻē aʻe, ʻo ka membrane ePTFE wale nō ka membrane hiki ke hoʻohana paʻa ʻia no ka manawa lōʻihi me ka coefficient hoʻoili nuipaʻa kiʻekiʻe, a me nā pono o ka liʻiliʻi liʻiliʻi, ikaika kākoʻo ponoʻī a me ka hoʻouka ʻana kiʻekiʻe o ka hollow fiber membranes. ʻO ka PTFE hollow fiber membranes e huki nui i ka nānā ʻana i ke kula o nā contactors membrane.
Porous PTFE hollow fiber membranes ua hoomakaukauia ma ka extrusion-kaʻina hana, a me ka hoomakaukau kaʻina me ka huikau, extrusion milo, unidirectional kikoo a me ka sintering.Hoʻopili mua ʻia ka mea PTFE i hui pū ʻia ma kahi paʻi hakahaka e hana i kahi blank cylindrical.Hoʻopuka ʻia nā blanks i kaomi mua ʻia a wili ʻia ma 40-100 ° C.Ma hope o ka degreasing, hoʻonohonoho wela e loaʻa iā PTFE hollow fiber membrane.ʻO ka mahana wela o ka degreasing he 200-340 ° C, ka mahana hoʻonohonoho wela he 330-400 ° C, a ʻo ka manawa hoʻonohonoho wela he 45-500 s.ʻO ke ʻano microscopic he ʻano pōʻai poʻo (elliptical a circular) kokoke.
