lole PTFE, a i ʻole ka lole polytetrafluoroethylene, he lole hana kiʻekiʻe i hoʻohana nui ʻia ma nā ʻano he nui ma muli o kona mau waiwai wai ʻole maikaʻi loa, hanu ʻole, pale makani, a mehana.
ʻO ke kumu o ka lole PTFE he kiʻiʻoniʻoni microporous polytetrafluoroethylene, nona kahi ʻano microporous kū hoʻokahi 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 manawa ka nui ma mua o kahi mole mahu wai. No laila, hiki i ka lole PTFE ke ālai pono i ke komo ʻana o nā kulu wai me ka ʻae ʻana i ka mahu wai e hele manuahi, e hoʻokō ana i kahi hui kūpono o ka pale wai a me ka hanu. Loaʻa i kēia lole nā waiwai pale makani maikaʻi, a hiki i kona ʻano microporous ke pale pono i ka convection ea, no laila e mālama ana i ka mehana i loko o ke kapa.
1. Nā waiwai kumu o PTFE
Ua hoʻomohala mua ʻia ʻo PTFE e DuPont i nā makahiki 1940 a ua kapa ʻia ʻo ia ʻo "King of Plastics" no kāna hana koʻikoʻi. He paʻa loa ke ʻano molekala o PTFE, a he kiʻekiʻe loa ka ikehu hoʻopaʻa ma waena o nā ʻātoma kalapona a me nā ʻātoma fluorine, ka mea e hāʻawi iā PTFE i nā waiwai kupaianaha penei:
● Pale wai:He waiwai wai maikaʻi loa nā lole PTFE, a ʻaʻole hiki i nā mole wai ke komo i loko o ko lākou ʻili, no laila hoʻohana pinepine ʻia lākou e hana i nā lole a me nā lako wai ʻole.
● Ka hiki ke hanu:ʻOiai he pale wai, he ʻano microporous ko nā lole PTFE e hiki ai i ka mahu wai ke hele ma loko, e mālama ana i ka ʻoluʻolu o ka mea e ʻaʻahu ana. ʻO kēia waiwai e lilo ia i koho kūpono 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 ʻino e like me nā waikawa, alkalis, a me nā mea hoʻoheheʻe.
● Ke kū'ē ʻana i ka mahana:Hiki i nā lole PTFE ke noho paʻa i nā mahana wela loa, a ʻo kona pae mahana hana mai -200°C a i +260°C, kūpono no nā wahi wela kiʻekiʻe a haʻahaʻa paha.
● Ka helu haʻalulu haʻahaʻa:He ʻili laumania loa ko PTFE a he haʻahaʻa loa ke koina friction, no laila hoʻohana pinepine ʻia ia i nā ʻāpana ʻoihana e pono ai ke hōʻemi i ka friction.
● Ke kūpaʻa ʻana i ka ʻelemakule:He kūpaʻa loa ka PTFE i nā kukuna ultraviolet a me nā mea ʻē aʻe o ke kaiapuni, a ʻaʻole ia e ʻelemakule ma hope o ka hoʻohana lōʻihi.
I waena o lākou, ʻo ka hiʻohiʻona kaulana loa o ka lole PTFE ʻo ia kona kūpaʻa i ka palaho kemika. Hiki iā ia ke pale aku i ka ʻino ʻana o nā waikawa ikaika, nā 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 nukelea, olaola a me ke kemika a me nā lole pale kemika. Eia kekahi, loaʻa i ka lole PTFE nā hana antibacterial, antistatic, virus blocking a me nā hana ʻē aʻe, e lilo ia i mea nui i ke kahua o ka palekana lapaʻau.
I nā noi maoli, ua hui pū ʻia ka lole PTFE me ka nylon, polyester a me nā lole ʻē aʻe ma o kahi kaʻina hana lamination kūikawā e hana i kahi lole composite ʻelua-i-hoʻokahi a ʻekolu-i-hoʻokahi paha. ʻAʻole wale kēia lole composite e mālama i ka hana maikaʻi loa o ka kiʻiʻoniʻoni PTFE, akā loaʻa pū kekahi i ka ʻoluʻolu a me ke kūpaʻa o nā lole ʻē aʻe.
2. Nā kahua noi o nā lole PTFE
Ma muli o nā waiwai kūikawā o nā lole PTFE, ua hoʻohana nui ʻia ia ma nā ʻano he nui:
● Nā lole o waho:Hoʻohana pinepine ʻia nā lole PTFE e hana i nā ʻaʻahu pale wai a me ka hanu, nā lole komo 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 i ka mahana e lilo ia i mea kūpono no nā lole pale i nā ʻoihana kemika, ka ʻaila a me nā ʻoihana ʻē aʻe.
● Nā lako lapaʻau:Hoʻohana ʻia nā lole PTFE e hana i nā ʻaʻahu ʻokiʻoki, nā ʻōwili disinfection a me nā lako lapaʻau ʻē aʻe e hōʻoia i kahi kaiapuni sterile.
● Nā mea kānana:ʻO ke ʻano microporous o PTFE e hoʻolilo iā ia i mea kānana kūpono, i hoʻohana nui ʻia i ka hoʻomaʻemaʻe ʻana i ka ea, ka mālama wai a me nā mahina ʻē aʻe.
● Lewa:ʻO ke kūpaʻa wela o ka PTFE a me ke koina friction haʻahaʻa e hoʻohana ʻia ai i ke kahua aerospace, e like me nā sila a me nā mea insulation.
3. Ka palekana kaiapuni o nā lole PTFE
ʻOiai he nui nā pono o nā lole PTFE, ua huki pū ʻia ka nui o ka nānā ʻana i ko lākou palekana kaiapuni. He mea paʻakikī ke hoʻohaumia ʻia ka PTFE, a he hopena koʻikoʻi kona i ke kaiapuni ma hope o ka hoʻolei ʻia ʻana. No laila, pehea e hana hou ai a hoʻolei aku i nā lole PTFE ua lilo ia i mea nui. I kēia manawa, ke hoʻomohala nei kekahi mau ʻoihana i nā mea PTFE hiki ke hana hou ʻia e hōʻemi i ko lākou hopena i ke kaiapuni.
4. Hōʻuluʻulu Manaʻo
Ua lilo nā lole PTFE i mea makemake ʻia no nā noi kiʻekiʻe he nui ma muli o ko lākou kūpaʻa wai maikaʻi loa, ka hanu ʻana, ke kūpaʻa kemika, ke kūpaʻa wela a me nā waiwai ʻē aʻe. Inā he haʻuki waho, palekana ʻoihana, a i ʻole nā kahua lapaʻau a me ka aerospace, ua hōʻike nā lole PTFE i ko lākou mau pono kūikawā. Eia nō naʻe, me ka hoʻonui ʻana o ka ʻike kaiapuni, pehea e hana maikaʻi ai me ka ʻōpala o nā lole PTFE e lilo i kikowaena o ka noiʻi a me ka hoʻomohala ʻana i ka wā e hiki mai ana.
