lole PTFE, a polytetrafluoroethylene lole, he lole hana kiʻekiʻe i hoʻohana nui ʻia ma nā ʻano he nui ma muli o kona maikaʻi ʻole o ka wai, ka hanu, ka makani, a me nā mea mahana.
ʻO ke kumu o ka lole PTFE he kiʻiʻoniʻoni microporous polytetrafluoroethylene, nona kahi ʻano microporous kūʻokoʻa me ka nui o ka pore o 0.1-0.5 microns wale nō, ʻoi aku ka liʻiliʻi ma mua o ke anawaena o kahi mole wai, akā he mau tausani ka nui ma mua o ka mole wai mahu. No laila, hiki i ka lole PTFE ke hoʻopaʻa pono i ke komo ʻana o nā kulu wai i ka wā e ʻae ana i ka mahu wai e hele manuahi, e loaʻa ai kahi hui kūpono o ka wai a me ka hanu. He mau waiwai pale makani maikaʻi kēia lole, a hiki i kona ʻano microporous ke pale pono i ka convection o ka ea, a laila mālama ʻia ka mahana i loko o ke kapa.
1. Nā waiwai kumu o PTFE
Ua hoʻokumu mua ʻia ʻo PTFE e DuPont i nā makahiki 1940 a ua ʻike ʻia ʻo ia ʻo "King of Plastics" no kāna hana koʻikoʻi. ʻO ka molecular structure o PTFE he mea paʻa loa, a he kiʻekiʻe loa ka ikehu paʻa ma waena o nā kalapona kalapona a me nā ʻātoma fluorine, e hāʻawi ana iā PTFE i kēia mau mea kupaianaha:
● Paʻa wai:ʻO nā lole PTFE he mau waiwai waiʻole maikaʻi loa, a ʻaʻole hiki i nā molekala wai ke komo i ko lākou ʻili, no laila hoʻohana pinepine ʻia lākou e hana i nā lole wai a me nā lako.
● Hiki i ka hanu:ʻOiai ʻaʻohe wai, he ʻano microporous nā lole PTFE e hiki ai i ka mahu wai ke hele i loko, e mālama ana i ka ʻoluʻolu o ka mea hoʻohana. Hana kēia waiwai i mea koho maikaʻi no nā lole haʻuki waho a me nā lole pale.
● Ke kū'ē kemika:He kūpaʻa loa ka PTFE i ka hapa nui o nā kemika a aneane ʻaʻole i hoʻopilikia ʻia e nā mea corrosive e like me nā waikawa, alkalis, a me nā solvents.
● pale wela:Hiki i nā lole PTFE ke noho paʻa i nā wela wela, a ʻo kāna pae wela hana mai -200 ° C a +260 ° C, kūpono no nā wahi wela kiʻekiʻe a haʻahaʻa paha.
● ʻĀpana haʻahaʻa haʻahaʻa:ʻO ka PTFE he maʻemaʻe maikaʻi loa a he haʻahaʻa haʻahaʻa haʻahaʻa, no laila hoʻohana pinepine ʻia i nā ʻāpana ʻoihana e pono ai e hoʻemi i ka friction.
● Kūʻē ʻelemakule:He kūpaʻa loa ka PTFE i nā kukuna ultraviolet a me nā mea ʻē aʻe o ke kaiapuni, a ʻaʻole hiki ke ʻelemakule ma hope o ka hoʻohana lōʻihi.
I waena o lākou, ʻo ka hiʻohiʻona kaulana loa o ka lole PTFE ʻo ia ke kūpaʻa kino kino. Hiki iā ia ke pale aku i ka hoʻoneʻe ʻana o nā waikawa ikaika, alkalis ikaika a me nā mea kemika ʻē aʻe, no laila ua hoʻohana nui ʻia i nā lole kūikawā e like me nā lole pale nuklea, biological a me nā kemika a me nā lole pale kemika. Eia kekahi, he mea antibacterial ka lole PTFE, antistatic, virus blocking a me nā hana ʻē aʻe, he mea koʻikoʻi ia i ke kahua o ka pale olakino.
Ma nā noi maoli, ua hui pū ʻia ka lole PTFE me ka nylon, polyester a me nā lole ʻē aʻe ma o kahi kaʻina lamination kūikawā e hana ai i kahi ʻelua a i ʻole ʻekolu-i-hoʻokahi. ʻAʻole mālama wale kēia lole i ka hana maikaʻi loa o ke kiʻi ʻoniʻoni PTFE, akā loaʻa pū ka ʻoluʻolu a me ka lōʻihi o nā lole ʻē aʻe.
2. Nā kahua noi o nā lole PTFE
Ma muli o nā waiwai kūʻokoʻa o nā lole PTFE, ua hoʻohana nui ʻia i nā kula he nui:
● Nā lole waho:Hoʻohana pinepine ʻia nā lole PTFE no ka hana ʻana i nā ʻaʻahu wai a me ka hanu, nā pants a me nā kāmaʻa, kūpono no nā haʻuki waho e like me ka piʻi mauna a me ka ski.
● Nā lole pale ʻoihana:ʻO kona kūpaʻa kemika a me ke kūpaʻa wela e lilo ia i mea kūpono no ka lole pale i ka kemika, ka ʻaila a me nā ʻoihana ʻē aʻe.
● Nā lako lapaʻau:Hoʻohana ʻia nā lole PTFE no ka hana ʻana i nā ʻaʻahu ʻokiʻoki, nā kāwili disinfection a me nā lako lāʻau ʻē aʻe e hōʻoia ai i kahi kaiapuni sterile.
● kānana mea:ʻO ka microporous structure o PTFE e hana ia i mea kānana pono, i hoʻohana nui ʻia i ka hoʻomaʻemaʻe ʻana i ka ea, ka mālama wai a me nā māla ʻē aʻe.
● Aerospace:ʻO ke kūpaʻa wela o ka PTFE a me ka coefficient friction haʻahaʻa e hoʻohana ʻia i loko o ke kahua aerospace, e like me nā sila a me nā mea insulation.
3. Palena kaiapuni o nā lole PTFE
ʻOiai he nui nā pōmaikaʻi o nā lole PTFE, ua hoʻokipa nui ʻia kā lākou mālama kaiapuni. He mea paʻakikī ka hoʻohaʻahaʻa ʻana i ka PTFE, a loaʻa iā ia kekahi hopena i ke kaiapuni ma hope o ka hoʻolei ʻia ʻana. No laila, pehea e hana hou ai a hoʻolei i nā lole PTFE i lilo i mea koʻikoʻi. I kēia manawa, ke hoʻomohala nei kekahi mau ʻoihana i nā mea PTFE recyclable e hōʻemi i ko lākou hopena i ke kaiapuni.
4. Hōʻuluʻulu manaʻo
Ua lilo nā lole PTFE i mea makemake nui no nā noi kiʻekiʻe ma muli o ko lākou maikaʻi ʻole wai, ka hanu, ke kūpaʻa kemika, ka pale wela a me nā waiwai ʻē aʻe. Inā he haʻuki waho, palekana ʻoihana, a i ʻole nā mea lapaʻau a me ka aerospace, ua hōʻike nā lole PTFE i ko lākou mau pono kūʻokoʻa. Eia nō naʻe, me ka piʻi ʻana o ka ʻike kaiapuni, pehea e hoʻoponopono maikaʻi ai i ka ʻōpala o nā lole PTFE e lilo i kumu no ka noiʻi a me ka hoʻomohala ʻana.
