Pa'u Fluorine o se ituaiga o pa'u fa'akomepiuta o lo'o i ai ni fa'atomu o le fluorine. E sili ona lelei le vevela, faʻamaʻi faʻamaʻi, faʻamaʻi suauu ma vailaʻau faʻasaina. E masani ona faʻaaogaina i vaalele, vailaʻau vailaʻau, suauʻu, taʻavale ma isi matagaluega faʻapisinisi e pei o mea faʻamaufaʻailoga, mea faʻafefe ma mea faʻapipiʻi. O se pa'u fa'akomepiuta o lo'o i ai ni fa'atomu fluorine i lona fausaga mole.
E masani lava ona fa'aalia i le numera o fa'atomu fluorine o iunite o lo'o iai i totonu o le copolymer. Mo se faʻataʻitaʻiga, o le fluororubber 23 o se copolymer o le vinylidene fluoride ma le chlorotrifluoroethylene. Fluororubber e tetee i le maualuga o le vevela, suauu ma vailaʻau faʻamaʻi.
Tulaga lelei ole fluororubber:
1. E sili atu le maualuga o le tete'e o le vevela: o le vevela o le tautua e amata mai - 60 ℃ i le 250 ℃. Suau'u sili tete'e: o le tetee atu i le suauʻu suauʻu vevela maualuga, sulfur-o loʻo i ai lubricating suauu, suauʻu hydraulic, suauʻu diester, silicate ester ma isi suauu e sili atu nai lo isi paʻu.
3. Lelei le tete'e atu i auala corrosive malosi ma oxidant malosi; O lona mautu i ala fa'a'a'ala malosi e pei ole fuming nitric acid, concentrated sulfuric acid, hydrochloric acid, hydrogen peroxyide ma concentrated alkali e sili atu nai lo isi pa'u.
4. Lelei mea faʻainisinia, faʻapipiʻi eletise ma faʻamalosi faʻamalosi.
5. Lelei le tetee atu i le maualuga o le vacuum.
Fa'aoga lautele ole fluororubber:
1. Pe a afaina le paʻu fluorine i le susu ma le vai poʻo le maualuga o le vevela, e laʻititi le suiga. E tusa lava pe o le silicon dioxide e faʻatupuina e ala pupuu faʻamumu o loʻo avea pea ma insulator, e faʻamautinoa o loʻo faʻaauau pea le galue o mea eletise, o lea e talafeagai mo le faia o uaea, uaea ma uaea taʻitaʻia.
2. Fluoroplastic tube e mafai ona faʻaogaina mo le faʻafeiloaʻiina ma le faʻamaufaʻailogaina o vailaʻau malosi ma alkali, ausa, ea vevela, suauʻu vevela ma isi vai. E mafai foi ona faʻaaogaina mo mea faigaluega a le fale, moli ma masini faʻafomaʻi; 3. O le mamafa galue o le fluororubber tube (0.5-3.0 MPa) e mafai ona puipuia e ala i sooga faʻapipiʻi ma uamea uamea ufiufi upega.
4. O lo'o fa'aogaina fo'i le fasipepa fluoroplastic mo peleue uaea i le siosiomaga galue faigata.;
5. Fluororubber e tulaga ese le vevela maualuga ma corrosion tetee, ma ei ai le talaaga o le tupu o pa'u. E mafai ona gaosia i totonu o le paʻu paʻu, faʻapipiʻi mea faʻapipiʻi, ata tifaga, gasket, (framework) faʻamaufaʻailoga suauʻu, "O" mama, "V" mama, ma isi, lea e faʻaaogaina lautele i vaalele, taavale, suauʻu, alamanuia kemisi, fesoʻotaʻiga, meafaigaluega ma isi fanua.
E pei ona tatou iloa uma, e tatau ona faʻaogaina e le valve taʻitasi mea faʻamaufaʻailoga eseese, e pei o le ethylene propylene rubber (EPDM), nitrile rubber (NBR), polytetrafluoroethylene (PTFE), fluororubber (Viton), silicone rubber (SEP), vevela ma ofuina paʻu faʻafefe EPDM, carbide sima, uʻamea uʻamea.
