Impapuro za PTFE zigabanijwemo imbaho ​​zahinduwe, imbaho ​​zibumbabumbwe hamwe n'imbaho.

Isahani
Isahani ibumbabumbwe ikozwe muri polytetrafluoroethylene isigara ibumba ubushyuhe bwicyumba, hanyuma ikayungurura ikonjesha, kandi ubunini bwisahani ya PTFE yabumbwe ni5mm-200mm.
Ikibaho
Ingazi za PTFE zitunganywa no gusohora cyangwa guhindura inzira.Kuberako ibintu byiza cyane byo kunyerera, imbaraga zizewe hamwe no kuramba gukomeye, akenshi bikoreshwa mugutambuka kuntambwe, gushyigikira ibitonyanga, kuyobora inzira, nibindi.
Nibyo, ibicuruzwa bya PTFE byakozwe nuburyo ubwo aribwo bwose birahinduka cyane kandi bifite ibintu byuzuye birenze urugero.Ahanini ikoreshwa nkibikoresho byo gukwirakwiza amashanyarazi hamwe nimirongo ihura nibitangazamakuru byangirika, bifasha kunyerera, kashe ya gari ya moshi nibikoresho byo gusiga, bikoreshwa cyane mubikoresho bya chimique, farumasi, ibikoresho byo gusiga amarangi, ibigega byo kubikamo, iminara ya reaction, imiyoboro minini irwanya ruswa;Imashini, ubwubatsi, kunyerera ikiraro cyumuhanda, kuyobora inzira;gucapa no gusiga irangi, inganda zoroheje, inganda zimyenda irwanya ibikoresho, nibindi.
Ibyiza:
Ubushyuhe bwo hejuru - ubushyuhe bwo gukora kugeza260℃.
Kurwanya ubushyuhe buke - ubukanishi bwiza;5% kuramba birashobora gukomeza nubwo ubushyuhe bugabanuka kuri-196 ° C.
Kurwanya ruswa - kwinjizamo imiti myinshi nu mashanyarazi, aside ikomeye hamwe na alkali irwanya, amazi hamwe nudukoko dutandukanye.
Ikirere Kurwanya - Ifite ubuzima bwiza bwo gusaza bwa plastiki iyo ari yo yose.
Amavuta menshi - Coefficient yo hasi yo guterana mubikoresho bikomeye.
Kudafatana - ni ntoya ntoya hejuru yibikoresho bikomeye, ntabwo yubahiriza ikintu icyo aricyo cyose, kandi imiterere yubukanishi ifite coefficente ntoya cyane, gusa1/5 cya polyethylene, nikintu cyingenzi kiranga parfluorocarubone.Kandi kubera fluor- imbaraga za karubone intermolecular imbaraga ziri hasi cyane, PTFE ntabwo ifatanye.
Ntabwo ari uburozi - Ni inert physiologique, kandi ntigira ingaruka mbi iyo yatewe mumubiri nkumuyoboro wamaraso wimbaraga hamwe ningingo igihe kirekire.
Ibikoresho by'amashanyarazi PTFE ifite dielectric ihoraho kandi igihombo cya dielectric hejuru yumurongo mugari, hamwe na voltage yamenetse cyane, irwanya amajwi hamwe no kurwanya arc.
Kurwanya imirasire Kurwanya imirasire ya PTFE ni bibi (104rad), kandi yangijwe nimirasire yingufu nyinshi, kandi ibikoresho byamashanyarazi nubukanishi bya polymer bigabanuka cyane.Gusaba Polytetrafluoroethylene irashobora gutunganywa no kwikuramo cyangwa gukuramo;irashobora kandi gukorwa muburyo bwo gukwirakwiza amazi yo gutwikira, gutera akabariro cyangwa gukora fibre.PTFE ikoreshwa cyane mu mbaraga za atome, mu kirere, mu bikoresho bya elegitoroniki, mu mashanyarazi, mu miti, mu mashini, ibikoresho, ibikoresho, ubwubatsi, imyenda, ibiryo n’inganda nk’ubushyuhe bwo hejuru kandi buke, ibikoresho birwanya ruswa, ibikoresho byangiza, ibikoresho byo kurwanya inkoni, nibindi .
Kurwanya gusaza kwa Atmospheric: kurwanya imishwarara no gutwarwa gake: kumara igihe kinini ikirere, ubuso n'imikorere ntibigihinduka.
Kudakongoka: Indangagaciro ya ogisijeni iri munsi90 .
Kurwanya aside na alkali: kudashonga muri acide ikomeye, alkalis hamwe na solge organic.
Kurwanya Oxidation: birashobora kurwanya ruswa ya okiside ikomeye.
Acide na alkaline: Ntaho ibogamiye.
Imiterere ya mashini ya PTFE iroroshye.Ifite ingufu nke cyane.
Polytetrafluoroethylene(F4, PTFE)ifite urukurikirane rw'imikorere myiza: ubushyuhe bwo hejuru burwanya - gukoresha igihe kirekire gukoresha ubushyuhe bwa200 ~ 260dogere, ubushyuhe buke bwo guhangana - biracyoroshye kuri-100impamyabumenyi;Kurwanya ruswa - kurwanya aqua regia hamwe nudukoko twose;Kurwanya ikirere - ubuzima bwiza bwo gusaza muri plastiki;amavuta menshi - hamwe na coefficient ntoya yo guterana (0.04) muri plastiki;kudafatika - hamwe nuburemere buke bwo hejuru mubikoresho bikomeye nta kwizirika kubintu byose;idafite uburozi - inert physiologique;Ibikoresho byiza byamashanyarazi, nicyiciro cyizaC ibikoresho.
