Mea palasitika Poly tetra fluoroethylene (PTFE), e masani ona taʻua o le "tupu o palasitika", o se polymer polymerized e le ethylene tetrafluoroethylene o se monomer. White waxy, translucent, vevela lelei ma le malulu, e mafai ona faʻaaogaina i le -180 ~ 260 C mo se taimi umi. O lenei mea e iai uiga o le anti - acid, anti - alkali, anti - solvents organic eseese, toetoe lava a le mafai ona faʻafefe i soʻo uma. I le taimi lava e tasi, o le polytetrafluoroethylene o loʻo i ai uiga o le maualuga o le vevela, o lona coefficient o feteʻenaʻiga e matua maualalo, o lea e mafai ai ona faʻaaogaina mo le lubrication, ae faʻafaigofie foi ona faʻamama le ufiufi lelei i totonu o le paipa vai Mea palasitika Poly tetra fluoroethylene (PTFE) , e masani ona taʻua o le "tupu o palasitika", o se polymer polymerized e le ethylene tetrafluoroethylene o se monomer.

I le taimi lava e tasi, o le polytetrafluoroethylene o loʻo i ai uiga o le maualuga o le vevela, o lona coefficient o feteʻenaʻiga e matua maualalo, o lea e mafai ai ona faʻaaogaina mo le lubrication, ae faʻafaigofie foi ona faʻamama le ufiufi lelei i totonu o le paipa vai.
Faʻamau i le vevela masani ma le mamafa, aloese mai le susu ma le vevela, leai se mea faʻafefete moni i le maualuga o le vevela, faʻagesegese lemu i luga ole 450 ℃ ma liliu saʻo ile kesi. I le 327 ℃, na faʻafuaseʻi ona mou atu le malosi faʻainisinia. E le mafai ona solu i so'o se solvent.
E ese mai i lona gafatia e tali atu ai i metala alkali liusuavai, e le afaina i le tafia e so o se mea, ma e le suia e tusa lava pe vela i le hydrofluoric acid, aqua roya, po o le fuming sulfuric acid, po o le sodium hydroxide.2. Paʻepaʻe, leai se manogi, leai se tofo ma le oona paʻu, e masani ona taʻua o le "tupu o palasitika".
O loʻo i ai le faʻamautuina o vailaʻau sili ona lelei, faʻamaʻi faʻamaʻi, faʻamaufaʻailoga, maualuga le viscosity, faʻapipiʻi eletise ma le faʻamalosia lelei o le matua.
Teteʻe maualuga vevela, faʻaogaina le vevela e oʻo atu i le 250 ℃. Low temperature resistance, maualalo le vevela o loʻo i ai le malosi faʻainisinia lelei, e tusa lava pe pa'ū le vevela i le -196 ℃, e mafai ona tausia le 5% elongation.
Tete'e o le corrosion, o le tele o vaila'au ma solvents e fa'aalia ai le inert, malosi malosi ma alkali, vai ma le tele o solvents fa'aletino. Lelei le tau, sili atu le soifua matua o palasitika.
Lubrication maualuga, o le mea mautu fesiitai coefficient o le maualalo.
Le fa'apipi'i, o le mea mautu o le la'ititi la'ititi o luga, e le pipii i so'o se mea.
E le o'ona, ma le physiological inertia, e pei o toto fa'afugaga ma totoga ua totoina i totonu o le tino mo se taimi umi e aunoa ma ni mea leaga.
Fa'aaoga lautele i masini, meafaifa'aili, vaega ta'avale, eletise ma fa'aeletoroni, nofoaafi, meafale, feso'ota'iga, masini ie, mea tau ta'aloga ma taimi paganoa, paipa suau'u, tane suau'u ma nisi mea fa'ainisinia sa'o.

SPCT66G15/20/30 | 15%-30% | HB/V0 | Toe fa'aleleia atili le ofuina, umi le fa'aogaina o le vevela, tulaga mautu e fa'agata fa'ama'i, maualuga maualuga, fetolofi. PTFE tetee i acids ma faavae, tetee i solvents organic eseese, ma e toetoe lava le mafai ona solu i solvents uma. I le taimi lava e tasi ma uiga maualuga o le vevela, o lona faʻaupuga faʻafefe e matua maualalo, o lea e mafai ai ona faʻaaogaina mo le lubrication. Faʻatasi ma le PPS, PPA, PA66, PA46, MOS2, e mafai ona faʻaleleia atili ai le faʻaogaina o le ofuina, feteʻenaʻiga ma mea faʻafefe o nei mea. Faʻaaogaina lautele e fai ai mea faʻaoga, bearings ma pulleys, faʻaaogaina foi e sui ai le matafaioi o le lubrication o vaega uʻamea, faʻaitiitia le mamafa o vaega ma faʻaitiitia tau tausiga. |
