He mea ʻupena ka PTFE mesh i hana ʻia me ka polytetrafluoroethylene (PTFE). He nui kona mau waiwai maikaʻi loa:
1. Ke kū'ē wela kiʻekiʻe:Hiki ke hoʻohana ʻia ka ʻupena PTFE i kahi pae mahana ākea. Hiki iā ia ke mālama i ka hana maikaʻi ma waena o -180 ℃ a me 260 ℃, kahi e lilo ai ia i mea pono loa i kekahi mau wahi wela kiʻekiʻe e like me ka kānana a me ka pale ʻana. No ka laʻana, i loko o nā lako kānana kinoea flue o kekahi mau umu ʻoihana,ʻUpena PTFEhiki ke kū i ka hopena o ke kinoea flue wela kiʻekiʻe me ka ʻole o ka hoʻololi a hōʻino paha i nā mahana kiʻekiʻe e like me nā mea maʻamau.
2. Paʻa kemika:ʻAʻole ia e pala i kekahi mau mea kemika. Inā he waikawa ikaika, alkali ikaika a i ʻole ka mea hoʻoheheʻe organik, he paʻakikī ke pala i ka PTFE mesh. I ka kānana pipeline o ka ʻoihana kemika, ka pale ʻana i nā ipu hana kemika, a me nā mea ʻē aʻe, hiki i ka PTFE mesh ke pale pono i ka pala o nā mea kemika a hoʻolōʻihi i ke ola lawelawe o nā lako. No ka laʻana, i ke kaʻina hana hana sulfuric acid, ʻaʻole e pala ka PTFE mesh i hoʻohana ʻia e kānana i ka noe sulfuric acid e ka sulfuric acid a hiki ke hoʻopau pono i ka hana kānana.
3. Ka helu haʻahaʻa haʻahaʻa:He laumania loa ka ʻili o ka PTFE mesh a he haʻahaʻa loa kona coefficient friction. ʻO kēia ka mea e hana maikaʻi ai i kekahi mau hiʻohiʻona noi e pono ai ka friction haʻahaʻa. No ka laʻana, i loko o nā uhi pale o kekahi mau ʻāpana mechanical, hiki i ka PTFE mesh ke hōʻemi i ka friction ma waena o nā ʻāpana mechanical a me nā uhi pale, hoʻemi i ka ʻaʻahu, a hoʻomaikaʻi i ka pono hana o nā ʻāpana mechanical.
4. Hoʻopaʻa uila maikaʻi:He mea hoʻokaʻawale uila maikaʻi loa ia. I ka pale ʻana i nā lako uila, ka pale ʻana i ka hoʻokaʻawale ʻana o nā uea a me nā kaula, a pēlā aku, hiki i ka PTFE mesh ke pāʻani i kahi hana hoʻokaʻawale maikaʻi. No ka laʻana, i loko o ka papa hoʻokaʻawale o kekahi mau kaula uila kiʻekiʻe, hiki i ka PTFE mesh ke pale i ka liki ʻana o ke au a hōʻoia i ka palekana o ka hoʻoili mana.
5.Breathability a me ka permeability wai:Wahi a nā kaʻina hana like ʻole, hiki ke hana ʻia ka ʻupena PTFE i nā huahana me nā ʻano hanu like ʻole a me ka permeability wai. I loko o kekahi mau lole hanu a me ka pale wai, hiki i ka ʻupena PTFE ke ālai i ke komo ʻana o nā molekala wai me ka ʻae ʻana i ka mahu wai e hele ma waena, e mālama ana i ka mea ʻaʻahu i maloʻo a ʻoluʻolu hoʻi.
He aha nā noi kikoʻī o ka PTFE mesh i ka ʻoihana?
He ākea nā noi ʻoihana kikoʻī o ka PTFE mesh. Eia kekahi o nā wahi noi nui:
1. ʻOihana kemika
Hoʻomaʻemaʻe kinoea a me ka kānana wai: Hoʻohana pinepine ʻia ka ʻupena PTFE i nā ʻōnaehana kānana kemika ma muli o kona kūpaʻa maikaʻi loa i ka pala a me nā waiwai ʻaʻole e pipili. Hiki iā ia ke lawelawe pono i nā mea ʻino, kiʻekiʻe-viscosity, ʻawahia a me nā mea ʻino.
Ka palekana o ka paipu a me nā lako: Hoʻohana ʻia nā mea PTFE e hana i nā paipu, nā valves, nā pamu a me nā sila e pale i nā lako mai ka pala e nā kemika.
2. ʻOihana meaʻai a me nā lāʻau lapaʻau
Kānana ea a me ka wai: ʻAʻohe ʻawahia ka ʻupena PTFE, ʻaʻohe ʻala a maʻalahi hoʻi e hoʻomaʻemaʻe. Hoʻohana nui ʻia ia i ka kānana ea i nā hale hana meaʻai a me ka kānana wai i nā kaʻina hana lāʻau lapaʻau.
Ka uhi ʻana a me nā sila o nā lako: I loko o ka uhi ʻana o loko a me nā sila o nā lako hana meaʻai, hōʻoia nā mea PTFE i ka palekana o ka meaʻai a me ka lōʻihi o nā lako.
3. Kahua palekana kaiapuni
ʻO ka mālama ʻana i ke kinoea ʻōpala a me ka mālama ʻana i ka wai ʻino: Hoʻohana nui ʻia ka ʻupena PTFE i ka mālama ʻana i ka wai ʻino a me ka mālama ʻana i ke kinoea ʻōpala, a hiki ke kānana pono i ka wai ʻino a me ke kinoea ʻōpala e loaʻa ana nā mea ʻino loa e like me ka fluoride a me ka chloride.
Kaohi haumia uahi ʻoihana: Hana maikaʻi nā ʻeke kānana PTFE i ka kānana uahi wela kiʻekiʻe i nā ʻoihana e like me ka hoʻoheheʻe kila, ka hana sima a me ka hana mana wela. Hiki iā lākou ke kū i nā mahana kiʻekiʻe a hiki i 260°C, a he pololei ke kānana a me ka hana hoʻomaʻemaʻe maikaʻi.
4. ʻOihana ʻaila a me ke kinoea
ʻŌnaehana kānana aila a me ke kinoea: Hoʻohana pinepine ʻia ka PTFE mesh i nā ʻōnaehana kānana i ka wā o ka unuhi ʻana i ka aila a me ke kinoea, ka hana ʻana a me ka halihali ma muli o kona kūpaʻa maikaʻi loa i ka mahana a me ke kūpaʻa kemika.
5. ʻOihana ikehu
ʻO ka ikehu nuklea a me ka makani: I ka kānana ʻana o nā kinoea radioactive i loko o nā mea kanu mana nuklea a me ka kānana ea i loko o nā turbine makani, ua lilo ka PTFE mesh i mea kānana kūpono ma muli o kona mau waiwai uila maikaʻi loa a me ka hiki ʻole ke lapalapa.
6. Kahua mokulele
ʻŌnaehana kānana kinoea a me ka wai: Hoʻohana nui ʻia ka PTFE mesh i nā ʻōnaehana kānana kinoea a me ka wai i nā mokulele a me nā mokulele mokulele ma muli o kona mau waiwai uila maikaʻi loa a me ka pale ʻole i ka lapalapa ʻana.
7. Nā noi ʻē aʻe
Nā lako uila a me nā lako uila: ʻO nā waiwai insulation uila o nā mea PTFE e hoʻohana nui ʻia i ka insulation uwea, nā papa kaapuni i paʻi ʻia a me nā ʻāpana insulating o nā lako uila kiʻekiʻe.
Nā mea lapaʻau: ʻO ka maʻemaʻe kiʻekiʻe o ka PTFE a me ke kūpaʻa kemika e lilo ia i mea kūpono no nā mea lapaʻau e like me nā catheters, nā valves a me nā mea hoʻohui.
He kuleana koʻikoʻi ko PTFE mesh ma nā ʻoihana ʻoihana he nui ma muli o kona kūpaʻa wela kiʻekiʻe, kūpaʻa i ka pala, haʻahaʻa haʻalulu a me nā waiwai ʻaʻole e pipili.
