ʻElua ʻano oNā papa PTFE: hoʻoheheʻe a me ka skiving/huli.Hana ʻia ka pā hoʻoheheʻe me ka polytetrafluoroethylene resin ma ka hoʻoheheʻe ʻana i ka lumi wela, a laila sintered a hoʻomaha.Hana ʻia ka pā hoʻohuli i ka resin PTFE ma ke kaomi ʻana, sintering, a me ka peeling.
ʻO ka pā PTFE ka mea ʻoi aku ka maikaʻi o ka pale ʻana i ka abrasion ma waena o nā plastik ʻenekinia āpau a ʻo ia ka mea ʻoi loa ka maka.ʻOi aku ke kiʻekiʻe o ke kaumaha molekala, ʻoi aku ka ʻoi aku o ka ʻaʻahu ʻana i nā mea, ʻoi aku ka nui o nā mea metala (e like me ke kila kalapona, ke kila kila, ke keleawe, etc.).No ka laʻana, ʻo nā paipu UHMW-pe ke ola lawelawe o 4-6 mau manawa o nā paipu kila ma lalo o nā kūlana o ka corrosion ikaika a me ka lole kiʻekiʻe, a ua hoʻonui ʻia ka pono o ka hoʻouna ʻana e 20%.Hōʻike piha ia i ke kūlana kiʻekiʻe o "ka mālama ʻana i ka ikehu, ka mālama ʻana i ke kaiapuni, ka hoʻokele waiwai, a me ka hana kiʻekiʻe".
He aha nā pōmaikaʻi o ka pā PTFE?
Ke kū'ē i ka wela kiʻekiʻe- Hiki i ka mahana hana ke hiki i 250 ℃.
Kūʻai haʻahaʻa haʻahaʻa- Loaʻa ka paʻakikī mechanical maikaʻi;ʻoiai inā hāʻule ka mahana i -196 ℃, hiki iā ia ke mālama i ka 5% elongation.
ʻO ke kūpaʻa ʻino- He inert ia i ka hapa nui o nā kemika a me nā mea hoʻoheheʻe, a hiki ke kū i nā waikawa ikaika a me nā alkalis, ka wai a me nā mea hoʻoheheʻe kūlohelohe.
Kūleʻa i ka wā- Loaʻa i ke ola ʻelemakule maikaʻi loa ma waena o nā plastics.
Lubrication kiʻekiʻe- ʻO ka helu haʻahaʻa haʻahaʻa o ka friction ma waena o nā mea paʻa.
Hoʻopili ʻole- ʻO ia ka liʻiliʻi liʻiliʻi ma waena o nā mea paʻa a ʻaʻole pili i kekahi mea.He liʻiliʻi loa ka ʻāpana friction o nā waiwai mechanical, he 1/5 wale nō o ka polyethylene, he mea nui ia o ka ʻili perfluorocarbon.Eia hou, no ka mea, he haʻahaʻa loa ka fluorine-carbon kaulahao intermolecular ikaika, ʻaʻole pili ka PTFE.
ʻAʻohe mea ʻawaʻawa- Me ka physiological inertness, implantation lōʻihi o nā kīʻaha koko a me nā kino i loko o ke kino me ka ʻole o nā hopena ʻino.
ʻO ka laulā noi o ka pā PTFE penei:
1. Ke hoʻohana nei i nā hiʻohiʻona o ka haʻahaʻa friction coefficient, ua hoʻohana ʻia no ka ʻaila ʻaila derrick slide veneer, dock slide veneer, river dam gate slide veneer, bridge telescopic support slide veneer, nā mea mīkini like ʻole, nā mīkini ʻoluʻolu, Grinder, planer sliding guide veneer , etc.
2. Ke hoʻohana nei i kāna mau waiwai lāʻau ʻole, ua hoʻohana ʻia ia i ka ʻoihana kō, ʻoihana lole, meaʻai, a me ka baka baking conveyor kāʻei, paʻi, a me ka ʻoihana hoʻoluʻu anti-sticking anti-corrosion coating layer o nā ʻano alakaʻi wili, etc.
3. ʻO ka hoʻohanaʻana i nā motika dielectric he hana maikaʻi loa ia a hoʻohanaʻia i loko o nā keʻena mana wela, nā pūnaewele electrolytic, nā apo sealing, nā kaapuni i paiʻia i nā mea uila a me nāʻoihana lolouila uila, nā mea i hoʻopaʻaʻia i ke keleawe, nā meaʻoki likeʻole a me nā mea hana kūikawā.
4. Ke hoʻohana nei i kona kūpaʻa kemika maikaʻi, hiki ke hoʻohana nui ʻia no nā gaskets, linings, valve discs, a me diaphragms of large-scale valves in petroleum, chemical, a me nā ʻoihana kemika, a me nā linings o nā moku pane like ʻole, nā pahu mālama. , a me nā hale kiaʻi pane, ka pā hoʻolaha, etc.
Hoʻohana ʻia o ka pā PTFE i hoʻololi ʻia
ʻO ka pā PTFE i hoʻololi ʻiaʻO ia ka mea i makemake ʻia no ka pale ʻana i ka corrosion-resistant, no laila he aha nā wahi noi o ka pā PTFE i hoʻololi ʻia?
Ma ke ʻano he mea hoʻopaʻa, hoʻohana nui ʻia nā papa PTFE i hoʻololi ʻia i nā mīkini, petrochemical, halihali, textile, a me nā ʻoihana kūkulu.Wahi a ke kinoea permeability i koho ʻia o ka pā PTFE ma hope o ka mālama ʻana, hiki ke hoʻohana ʻia e like me kahi mea hoʻokaʻawale e koho i ke kinoea a i ʻole ka wai, ʻoi aku ka kānana i nā wai corrosive.I nā makahiki i hala iho nei, ua hoʻohana ʻia ka pā PTFE i hoʻololi ʻia ma ke ʻano he ʻano hana, a e hoʻohana ʻia i nā ʻano ʻano like ʻole i ka wā e hiki mai ana.
