1. anti-corrosion
I loko o nā lako anticorrosion kemika, pipeline, mechanical manufacturing nā ʻano anti corrosion o nā ʻāpana, e like me ka paipu, nā valves, diaphragm, nā hui hoʻonui o ka paila.Hiki iā Porous PTFE ke like me ke ʻano corrosive ikaika o nā mea kānana.Ma muli o ka PTFE ʻaʻole i hoʻopaʻa ʻia i ka hopena, no laila, PTFE manufacturing reactor, hoʻohana ʻia ka hale kiaʻi distillation e hoʻomaʻemaʻe i nā koi o ka mea maʻemaʻe ultra he mea maikaʻi ia, akā hiki ke hoʻohana ʻia no nā mea kemika corrosion linings a me nā uhi.
2. lubrication, sila
Me ka PTFE e hana ana i nā ʻano kāʻei packing, gaskets, seals, valve seat ring, etc., me nā huahana PTFE filler like ʻole i hoʻohana ʻia i ka lawe ʻana i nā koi like ʻole o ka lubricating a me ka pale ʻana, ke apo piston a pēlā aku.No ka laʻana, ka hoʻohana 'ana i ka graphite PTFE alakai apo apo, hoʻohana 'ole i ka aila lubricated compressor;ʻO ke apo piston PTFE me ke one quartz i hoʻohana ʻia i ka mea hoʻoheheʻe oxygen;ʻO ke apo piston ʻaila-ʻole i hoʻopiha ʻia me ka graphite a me ka MoS2, ka mea hoʻoheheʻe i hoʻohana ʻia i ka helium, ʻoi aku ka maikaʻi o ka haʻahaʻa haʻahaʻa o -269 ℃;me MoS2, silica, pauka keleawe e like me ka hoʻopiha piha PTFE piston apo, ka ea compressor hana ana wela o 150 ℃ e holo ma luna o nā pier hiki maikaʻi;ke alahaka ma muli o ka hoʻonui ʻana i ka wela a me ka ʻoki ʻana me ka PTFE slider hiki ke hoʻihoʻi ʻia.
3. hoʻopololei uila
ʻO ka PTFE ma ke ʻano he uila insulating mea hoʻohana nui ʻia i nā koi o nā hiʻohiʻona kiʻekiʻe kiʻekiʻe maikaʻi a kūpaʻa loa i ka wela, ke kū anuanu, ke kū ʻana o ka wai, ke kū ʻana i ka corrosion, ka ʻelemakule a me nā manawa.No ka laʻana, hoʻohana ʻia i loko o kahi ākea o ka hoʻololi ʻana i ka wela o ka mokulele jet fierce, radar a me nā mea ʻē aʻe e like me ka insulation o ka mea uila uila kiʻekiʻe, kiʻekiʻe alapine cable, flexible cable, motor groove, capacitor insulation a me ka papa kaapuni paʻi.
4. lāʻau ʻole
Ma muli o ka PTFE a me nā mea ʻē aʻe ʻaʻole paʻa, i ka hana plastics, ka hoʻoili ʻana i ka meaʻai a me nā ʻoihana ʻē aʻe e hoʻokaʻawale nui ʻia, ʻo nā mea kuke i uhi ʻia me ka PTFE ʻaʻole hiki ke lilo i ʻaila ʻaila, kiʻi ʻoniʻoni wela welding maʻamau i hoʻohana ʻia i ka lole aniani PTFE e like me ka spacer viscous a pēlā aku.
