Gukoresha nibyiza byubuyobozi bwa PTFE

Ubwoko bwose bwibicuruzwa bya PTFE byagize uruhare runini mubukungu bwigihugu nkinganda zimiti, imashini, ibikoresho bya elegitoroniki, ibikoresho byamashanyarazi, inganda za gisirikare, ikirere, kurengera ibidukikije nikiraro.
Ikibaho cya Tetrafluoroethylene kibereye ubushyuhe bwa -180 ℃ ~ + 250 ℃.Ikoreshwa cyane cyane nk'ibikoresho byo gukwirakwiza amashanyarazi n'amashanyarazi kugirango bihuze n'ibitangazamakuru byangirika, bifasha kunyerera, kashe ya gari ya moshi n'ibikoresho byo gusiga.Ikoreshwa mu nganda zoroheje nibikoresho bikungahaye., Ikoreshwa cyane mubikoresho bya chimique, farumasi, ibikoresho byo gusiga amarangi, ibigega byo kubikamo, indobo yumunara, ibikoresho byo kurwanya ruswa kumiyoboro minini;indege, igisirikare n’izindi nganda ziremereye;imashini, ubwubatsi, kunyerera ikiraro cyumuhanda, kuyobora inzira;gucapa no gusiga irangi, inganda zoroheje, imyenda Ibikoresho byo kurwanya inganda, nibindi.
Ibyiza
Kurwanya ubushyuhe bwinshi - ubushyuhe bwakazi burashobora kugera kuri 250 ° C.
Kurwanya ubushyuhe buke - bifite ubukana bwiza;niyo ubushyuhe bwamanuka kuri -196 ° C, burashobora gukomeza kuramba kwa 5%.
Kurwanya ruswa - kwinjizamo imiti myinshi nu mashanyarazi, irwanya aside ikomeye na alkalis, amazi hamwe nudukoko dutandukanye.
Ikirere cyihanganira ikirere - gifite ubuzima bwiza bwo gusaza muri plastiki.
Amavuta menshi - coefficient yo hasi yo guterana mubikoresho bikomeye.
Kudafatana - ni ntoya yoroheje yubuso hagati yibikoresho bikomeye, ntabwo yubahiriza ikintu icyo aricyo cyose, kandi imiterere yubukanishi ifite coefficient ntoya cyane, ikaba ari 1/5 gusa cya polyethylene, nikintu cyingenzi kiranga parfluorocarubone Ubuso.Kandi kubera imbaraga nke cyane za intermolecular zumunyururu wa fluor-karubone, PTFE ntabwo ifatanye.
Ntabwo ari uburozi - ni inert physiologique kandi ntigira ingaruka mbi iyo yatewe mumubiri nkumuyoboro wamaraso hamwe ningingo igihe kirekire.
Ibikoresho byamashanyarazi PTFE ifite dielectric idahoraho hamwe nigihombo cya dielectric mumurongo mugari, hamwe na voltage yamenetse cyane, irwanya amajwi hamwe no kurwanya arc.
Imirasire irwanya imishwarara ya polytetrafluoroethylene irakennye (rad 104), kandi yangizwa nimirasire y’ingufu nyinshi, kandi amashanyarazi nubukanishi bwa polymer bigabanuka cyane.Porogaramu PTFE irashobora gutunganywa no kwikuramo cyangwa gukuramo;irashobora kandi gukorwa muburyo bwo gukwirakwiza amazi yo gutwikira, gutera akabariro cyangwa gukora fibre.WT inganda.
Kurwanya gusaza kwa Atmospheric: kurwanya imishwarara no gutwarwa gake: kumara igihe kinini ikirere, ubuso n'imikorere ntibigihinduka.
Kudakongoka: Igipimo cya ogisijeni igabanya kiri munsi ya 90.
Kurwanya aside na alkali: kudashonga muri acide ikomeye, alkali ikomeye na solge organic.
Kurwanya Oxidation: Irashobora kurwanya ruswa ya okiside ikomeye.
Acide na alkaline: kutabogama.
Imiterere ya mashini ya PTFE iroroshye.Ifite ingufu nke cyane.
Polytetrafluoroethylene (F4, PTFE) ifite urukurikirane rwibikorwa byiza: kurwanya ubushyuhe bwinshi - gukoresha igihe kirekire ubushyuhe bwa dogere 200 ~ 260, ubushyuhe buke - buracyoroshye kuri dogere -100;Kurwanya ruswa - kurwanya aqua regia hamwe nudukoko twose;Kurwanya ikirere - ubuzima bwiza bwo gusaza muri plastiki;amavuta menshi-coefficient ntoya yo guterana (0.04) muri plastiki;kudafatika-umutwaro muto muto mubikoresho bikomeye udatsimbaraye kubintu byose;idafite uburozi-inert physiologique;Ibikoresho by'amashanyarazi bihebuje, ni ibikoresho byiza byo mu rwego rwa C.
