I loko o ke aupuni o ka ea kānana ʻoihana,ʻeke kānana PTFEua puka mai ma ke ʻano he hopena maikaʻi loa a hilinaʻi. Hoʻolālā ʻia kēia mau ʻeke e kū i nā kūlana paʻakikī like ʻole, e lilo ia i mea koʻikoʻi i nā ʻoihana lehulehu. Ma keia 'atikala, mākou e delve i loko o ka intricacies o PTFE kānana eke, e 'imi ana i ko lakou haku mele 'ana, pono, noi, a me ka lakou hoohalike ana me kekahi mau mea kānana e like me PVDF.
He aha ke kānana ʻeke PTFE?
ʻO kahi kānana ʻeke PTFE (Polytetrafluoroethylene) he ʻano mea kānana ea e hoʻohana ana i nā ʻeke i hana ʻia mai nā mea PTFE e hopu a wehe i nā mea haumia mai ka lewa. ʻO ka PTFE kahi fluoropolymer synthetic i ʻike ʻia no kona kūʻokoʻa kemika, kūpaʻa wela, a me ka haʻahaʻa haʻahaʻa. Hana kēia mau waiwai i ka PTFE i mea kūpono no ka hana ʻana i nā ʻeke kānana maikaʻi loa a paʻa.
Hana ʻia nā ʻeke kānana PTFE me ka hoʻohana ʻana i ka hui pū ʻana o ka PTFE staple fibers, PTFE scrims, a hoʻonui ʻia.PTFE (ePTFE).. ʻO kēia hana ka mea e hiki ai i nā ʻeke ke kānana maikaʻi i nā ʻāpana maikaʻi loa a me nā mea haumia mai ka lewa. ʻO ka membrane ePTFE, ʻo ia hoʻi, he hana koʻikoʻi i ka hoʻokō ʻana i ka pono kānana kiʻekiʻe. Hoʻokumu ia i kahi papa honua e pale ai i nā ʻāpana lepo mai ke komo hohonu ʻana i loko o ka media kānana, e hōʻoia i ka mālama ʻana o nā ʻeke i kā lākou hana no ka manawa lōʻihi.
ʻO kekahi o nā pōmaikaʻi nui o nā ʻeke kānana PTFE ʻo ko lākou hiki ke mālama i kahi ākea o nā kūlana kemika. Hiki iā lākou ke kūpaʻa i nā kinoea a me nā mea kemika nui loa, e kūpono ana iā lākou no ka hoʻohana ʻana i nā ʻoihana e like me nā mea kanu kemika a me nā hale hana lāʻau. Hoʻohui hou, hōʻike nā ʻeke kānana PTFE i ke kūpaʻa kiʻekiʻe kiʻekiʻe, e ʻae iā lākou e hana maikaʻi i nā kaiapuni me nā mahana kiʻekiʻe, e like me nā keʻena puhi ʻōpala.
ʻO ka lōʻihi o nā ʻeke kānana PTFE kekahi hiʻohiʻona kaulana. Ke hoʻohālikelike ʻia me nā ʻano ʻeke kānana ʻē aʻe, ʻoi aku ka lōʻihi o ka lawelawe ʻana o nā ʻeke PTFE. ʻO kēia lōʻihi o ke ola e unuhi i ka hoʻemi ʻana i nā kumukūʻai mālama a me ka manawa haʻahaʻa no nā hana ʻoihana. Eia kekahi, ʻoi aku ka maikaʻi o nā ʻeke kānana PTFE i ka hopu ʻana i nā ʻāpana maikaʻi, e hōʻoia i ka maʻemaʻe o ka ea e puka ana i ka ʻōnaehana kānana. ʻO kā lākou ʻano maʻalahi e hoʻomaʻemaʻe e hoʻomaikaʻi hou i kā lākou hana, ʻoiai hiki ke wehe koke ʻia nā pōpō lepo, e mālama ana i ka pono kānana maikaʻi.
Nā noi o nā ʻeke kānana PTFE
ʻO ka versatility o nā ʻeke kānana PTFE e kūpono iā lākou no kahi ākea o nā noi ʻoihana. I loko o nā kiln sima, no ka laʻana, hoʻohana ʻia nā ʻeke kānana PTFE e kānana i ka lepo a me nā mea haumia i hana ʻia i ka wā o ke kaʻina hana sima. ʻO ke kūpaʻa wela kiʻekiʻe o kēia mau ʻeke e hiki ai iā lākou ke pale i nā wela wela i loaʻa i nā kiln sima, e hōʻoiaʻiʻo ana i ka hana filtration kūpaʻa a hilinaʻi.
Ma ka ʻoihana hoʻoheheʻe ʻōpala, he kuleana koʻikoʻi nā ʻeke kānana PTFE i ka hopu ʻana i nā mea haumia ʻino a me nā ʻāpana i hoʻokuʻu ʻia i ka wā o ke kaʻina hana. ʻO kā lākou kūpaʻa kemika a me nā hiki ke wela kiʻekiʻe e lilo lākou i koho kūpono no kēia noi koi. Pēlā nō, i loko o nā mea kanu kemika a me nā hale hana lāʻau lapaʻau, hoʻohana ʻia nā ʻeke kānana PTFE e kānana i nā kinoea a me nā ʻāpana kemika, e pale ana i ke kaiapuni a me ka hōʻoia ʻana i ka palekana o nā limahana.
Ma waho aʻe o kēia mau ʻoihana kikoʻī, hoʻohana ʻia nā ʻeke kānana PTFE i nā hale hana metallurgic, nā mea kanu mana, a me nā wahi ʻoihana ʻē aʻe kahi e koi ʻia ai ka kānana ea kiʻekiʻe. ʻO ko lākou hiki ke mālama i nā ukana lepo nui a me nā kūlana hana paʻakikī e lilo lākou i koho hilinaʻi no ka mālama ʻana i ka maikaʻi o ka ea a me ka hoʻokō ʻana i nā lula kaiapuni.
ʻO ka ʻokoʻa ma waena o nā kānana PTFE a me DF PV
I ka wā e pili ana i ka kānana ea ʻoihana, ʻo nā kānana PTFE a me PVDF (Polyvinylidene Fluoride) nā mea hoʻohana maʻamau. Eia nō naʻe, aia kekahi mau ʻokoʻa koʻikoʻi ma waena o nā mea ʻelua e hiki ke hoʻopili i ko lākou kūpono no nā noi kikoʻī.
Palekana Kemika
Kaulana ʻia nā kānana PTFE no ko lākou kūʻokoʻa kemika. Hiki iā lākou ke kūpaʻa i ka nui o nā kemika corrosive a me nā kinoea, e hoʻolilo iā lākou i mea kūpono no ka hoʻohana ʻana i nā kaiapuni kemika nui loa. ʻO kēia kiʻekiʻe o ke kūpaʻa kemika ma muli o nā waiwai kūlohelohe o PTFE, ʻo ia ka fluoropolymer me kahi ʻano molekala paʻa.
ʻO nā kānana PVDF, ma ka ʻaoʻao ʻē aʻe, hōʻike pū kekahi i ke kūpaʻa kemika maikaʻi, akā ʻaʻole like lākou i kemika e like me PTFE. ʻOiai hiki i ka PVDF ke lawelawe i nā ʻano kemika like ʻole, ʻaʻole kūpono paha ia no nā noi e pili ana i nā kemika ʻoi loa. Ma ia mau hihia, ʻo nā kānana PTFE ka mea i koho ʻia ma muli o ko lākou kūpaʻa kemika kiʻekiʻe.
Kūleʻa wela
Loaʻa i nā kānana PTFE kahi pale wela kiʻekiʻe, e ʻae iā lākou e hana maikaʻi i nā wahi me nā mahana kiʻekiʻe. ʻO kēia ka mea kūpono iā lākou no nā noi e like me ka hoʻoheheʻe ʻana i ka ʻōpala a me ka kānana kiln sima, kahi e maʻamau ai nā wela kiʻekiʻe. ʻO ka hiki i ka PTFE ke mālama i kāna hana i nā mahana kiʻekiʻe me ka ʻole o ka hoʻohaʻahaʻa ʻana he mea maikaʻi loa ia i kēia mau kūlana koi.
Loaʻa i nā kānana PVDF ke kūpaʻa wela maikaʻi, akā ʻoi aku ka haʻahaʻa o ka mahana hana kiʻekiʻe ma mua o nā kānana PTFE. ʻO ia hoʻi, ʻoiai hiki i nā kānana PVDF ke mālama i nā wela haʻahaʻa haʻahaʻa, ʻaʻole maikaʻi paha lākou i nā noi wela kiʻekiʻe loa. No laila, i ke koho ʻana i kahi mea kānana, pono e noʻonoʻo i nā koi wela kūikawā o ka noi e hōʻoia i ka hana maikaʻi loa.
Hoʻomaʻamaʻa kānana
Hoʻolālā ʻia nā kānana PTFE a me PVDF e hāʻawi i ka pono kānana kiʻekiʻe, e hopu ana i nā ʻāpana maikaʻi a me nā mea haumia mai ka lewa. Eia nō naʻe, loaʻa pinepine nā kānana PTFE i kahi liʻiliʻi e pili ana i ka pono o ka kānana ma muli o nā waiwai kūikawā o ka membrane eFEPT i hoʻohana ʻia i kā lākou hana. Hoʻokumu ka membrane ePTFE i kahi papa honua e pale ai i nā ʻāpana lepo mai ke komo hohonu ʻana i loko o ka media kānana, e hopena i ka hopu ʻana a me ka wehe ʻana.
Hāʻawi pū nā kānana PVDF i ka maikaʻi kānana maikaʻi, akā ʻaʻole hiki ke hoʻokō i ka pae like o ka hopu ʻana i nā ʻāpana maikaʻi e like me nā kānana PTFE. Hiki ke koʻikoʻi kēia ʻokoʻa i ka pono kānana i nā noi kahi e koi ʻia ai ka haʻahaʻa haʻahaʻa. Ma ia mau hihia, ʻoi aku ka maikaʻi o nā kānana PTFE i nā kūlana hoʻokuʻu hoʻokuʻu.
Ola lawelawe
ʻO ke ola lawelawe o kahi ʻeke kānana he mea nui e noʻonoʻo ai i nā hana ʻoihana, no ka mea e pili pono ana i nā kumukūʻai mālama a me ka manawa haʻahaʻa. ʻIke ʻia nā ʻeke kānana PTFE no ko lākou ola lawelawe lōʻihi, hiki ke hoʻohālikelike ʻia i ko lākou kūpaʻa a me ke kūʻē ʻana i nā ʻano mea kaiapuni. ʻO ka lōʻihi o ke ola ʻana o nā ʻeke PTFE e hōʻemi ana i ka pinepine o ka hoʻololi ʻana i ka kānana, e hopena i nā kumukūʻai mālama haʻahaʻa a hoʻonui i ka pono hana.
Loaʻa i nā ʻeke kānana PVDF ke ola lawelawe kūpono, akā ʻoi aku ka pōkole ma mua o nā ʻeke PTFE. ʻO ia ke ʻano o nā ʻeke PVDF pono e hoʻololi pinepine ʻia, e alakaʻi ana i nā kumukūʻai mālama kiʻekiʻe a me ka manawa haʻahaʻa no nā loli kānana. No laila, i nā noi i mea koʻikoʻi ka hoʻohaʻahaʻa ʻana i ka mālama ʻana a me ka hoʻonui ʻana i ka manawa hana, ʻoi aku ka maikaʻi o nā ʻeke kānana PTFE.
Noonoo Kumukuai
ʻOiai ke hāʻawi nei nā ʻeke kānana PTFE i nā pono he nui, he mea nui e noʻonoʻo i ka hopena o ka hoʻohana ʻana i kēia mea. ʻOi aku ka nui o nā kānana PTFE ma mua o nā kānana PVDF ma muli o nā kaʻina hana kiʻekiʻe a me nā mea kiʻekiʻe kiʻekiʻe. Hiki i kēia kumukūʻai kiʻekiʻe ke lilo i kumu koʻikoʻi no kekahi mau hana ʻoihana, ʻoi aku ka nui o nā kālā paʻa.
Eia naʻe, he mea nui e kaupaona i ke kumu kūʻai mua i nā pono lōʻihi o ka hoʻohana ʻana i nā ʻeke kānana PTFE. ʻO ka lōʻihi o ke ola lawelawe, ʻoi aku ka maikaʻi o ka kānana ʻana, a me nā koi mālama pono ʻana o nā ʻeke PTFE hiki ke hopena i ka mālama kālā i ka manawa. Eia hou, hiki i ka hiki o nā kānana PTFE ke hoʻokō i nā kūlana paʻakikī a hoʻokō i nā kūlana hoʻokuʻu paʻa hiki ke hāʻawi i ka waiwai nui i nā ʻōlelo o ka hoʻokō kaiapuni a me ka hilinaʻi o ka hana.
Ka hopena
Ua hoʻokumu nā ʻeke kānana PTFE iā lākou iho he hopena maikaʻi loa a hilinaʻi hoʻi no ka kānana ea ʻoihana. ʻO kā lākou kūʻokoʻa kemika kūʻokoʻa, nā mana wela kiʻekiʻe, ke ola lōʻihi o ka lawelawe ʻana, a me ka ʻoi aku ka maikaʻi o ka kānana ʻana e kūpono iā lākou no kahi ākea o nā noi koi. Mai nā kiln sima a hiki i nā mea kanu hoʻopau ʻia, hāʻawi nā ʻeke kānana PTFE i kahi ʻano ikaika a me ke ʻano o ka hopu ʻana i nā mea haumia a me ka hōʻoia ʻana i ka ea maʻemaʻe.
I ka hoʻohālikelike ʻana i nā kānana PTFE i nā kānana PVDF, ua akaka ka hāʻawi ʻana o PTFE i nā pono he nui ma ke ʻano o ke kemika a me ke kūpaʻa wela, ka pono kānana, a me ke ola lawelawe. Eia nō naʻe, pono e noʻonoʻo ʻia ke kumukūʻai kiʻekiʻe o nā kānana PTFE ma ke ʻano o nā koi kikoʻī a me nā kaohi kālā o kēlā me kēia hana ʻoihana. Ma ka loiloi pono ʻana i kēia mau mea, hiki i nā ʻoihana ke hoʻoholo i ka ʻike e pili ana i nā mea kānana kūpono loa no kā lākou pono kānana ea.
I ka hopena, he waiwai nui nā ʻeke kānana PTFE i ka hakakā ʻana i ka pollution ea a me ka mālama ʻana i nā kūlana kiʻekiʻe o ka ea. ʻO kā lākou mau waiwai kūʻokoʻa a me nā mea hiki ke hoʻokō iā lākou i koho maikaʻi ʻia no nā ʻoihana he nui e ʻimi nei i nā ʻoluʻolu kānana ea pono a maikaʻi.
