I ka mahana hea e hoʻohana ʻia ai ka palapala PTFE?

Ua ʻike ʻia ka pā Tetrafluoroethylene ma ke ʻano he mōʻī o nā plastics ma ke kahua o nā plastics, a ʻaʻole i ʻike ʻia kāna hana e nā plastics maʻamau, no laila hoʻohana maʻamau ia i nā wahi me nā wahi paʻakikī, e like me ka waikawa a me ka alkali, corrosive media a me ke kiʻekiʻe wela.No laila, he aha nā pōmaikaʻi o ka papa PTFE?

ʻO ka mea mua, loaʻa iā ia ke kū'ē wela kiʻekiʻe.E pili ana i ka hoʻohana ʻana i kēia manawa o ka tetrafluoroethylene sheet material, hiki i ka mea maka ke piʻi i 232 °C, a ʻo ke kiʻekiʻe kiʻekiʻe ma hope o ka hoʻi ʻana i ka hale paʻa hiki ke piʻi i kahi 150 °C, a ākea loa ka mahana hoʻohana.

Loaʻa i ka pepa PTFE nā waiwai dielectric maikaʻi loa, ka ikaika dielectric koʻikoʻi a me ke kūpaʻa arc, haʻahaʻa dielectric loss tangent, a me ka pale pale corona maikaʻi ʻole.ʻO ka pepa tetrafluoroethylene he maikaʻi ka hoʻoheheʻe wai ʻole, oxygen-free, UV a me ka pale ʻana i ka wā.ʻAʻole i loli ka ikaika o waho no ʻekolu mau makahiki, ʻo ka elongation wale nō i emi iho.ʻO nā kiʻiʻoniʻoni Teflon a me nā uhi e paʻa i ka wai a me ke kinoea ma muli o ko lākou porosity maikaʻi.Hiki i ka PTFE ke kūpono i nā mahana ambient ma waena o 190 degere a me 250 degere.Hiki ke wela a i ʻole ke anu hikiwawe, a i ʻole ke ʻano wela a me ke anu me ka ʻole o ka hopena.Ma waho aʻe o ka hoʻoponopono ʻana i nā pilikia hana kemika a me ka ʻaila, hiki i nā lau tetrafluoroethylene ke pāʻani i ka hana i nā lāʻau lapaʻau a me nā māla ʻē aʻe.Nui nā ʻāpana sealing ma ka mākeke i kēia lā, a me nā huahana gasket a i ʻole gasket.Eia kekahi, hoʻohana nui ʻia ʻo PTFE i nā mea me nā koina sealing, a hoʻohana maʻamau ʻia e like me Jinxining filler.ʻO ke kuleana o ka pepa PTFE he mea nui loa, no ka mea, he kuleana nui ka pepa PTFE, he nui o nā huahana, a he hana nui i nā ʻano āpau a me nā ʻāpana o ka mana.Hiki ke ʻike ʻia ka PTFE ma nā wahi āpau o ko mākou ola.

ʻO ka lua, ʻaʻohe ʻano o ka mea kemika, ʻaʻohe mea ʻino, hiki ke hoʻohana pono ʻia ka PTFE.Hiki ke ʻōlelo ʻia inā ʻaʻole hiki i ka pepa PTFE ke hoʻokō i nā koi kūpaʻa corrosion, ʻaʻole hiki ke hoʻohana ʻia nā mea plastik ʻē aʻe.Ma waho aʻe o kāna kūpaʻa kemika maikaʻi loa, ʻoi aku ka maikaʻi o kāna mau waiwai mechanical, e kūpono ia no ka hoʻohana ʻana i nā manawa me nā koli nui a me nā piko.

Hoʻohana nui ʻia ka pepa PTFE i nā plastics ʻenekinia e like me ke kiʻekiʻe kiʻekiʻe 260 ℃, haʻahaʻa haʻahaʻa -196 ℃, acid a me ka alkali corrosion resistance, weather resistance and non-toxicity.Hiki ke ʻike ʻia ka PTFE i ka ʻaila, kemika, ka lāʻau lapaʻau, ka uila a me nā ʻoihana meaʻai.Inā he mea ʻawaʻawa ka pā PTFE a maikaʻi ke pale ʻana i ka lole, he mea hoʻopaʻa sila maikaʻi.ʻO ka PTFE (Polytetrafluoroethylene, i hoʻopau ʻia ʻo PTFE), i kapa ʻia ʻo "non-stick coating" a i ʻole "mea maʻalahi e hoʻomaʻemaʻe".Loaʻa i kēia mea nā hiʻohiʻona o ka waikawa a me ke kūpaʻa alkali a me ke kū'ē ʻana i nā mea hoʻoheheʻe kūlohelohe, a aneane hiki ʻole ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe āpau.I ka manawa like, loaʻa i ka pā PTFE nā hiʻohiʻona o ke kūpaʻa wela kiʻekiʻe a me ka coefficient friction haʻahaʻa.Ma waho aʻe o ka lubrication, ua lilo ke kaʻina hana o ka uhi ʻana o ka pā PTFE i kahi uhi kūpono no ka hoʻomaʻemaʻe maʻalahi o ka papa o loko o nā paipu wai.
