Nibihe bikoresho ptfe tube ikozwe muri？
Kumenyekanisha ibicuruzwa
1 、Ptfe tubeni irindi zina rya polytetrafluoroethylene, impfunyapfunyo y'Icyongereza ni PTFE, (bakunze kwita "Plastike King, Hara"), naho imiti ni - (CF2-CF2) n-.Polytetrafluoroethylene yavumbuwe ku bw'impanuka mu 1938 na chimiste Dr. Roy J. Plunkett muri DuPont's Laboratoire ya Jackson muri New Jersey, muri Amerika Mugihe yagerageje gukora chlorofluorocarbon nshya Mugihe cya firigo ikomatanya.Ibicuruzwa byibi bikoresho muri rusange byitwa "gutwikira inkoni";nibikoresho bya sintetike ya polymer ikoresha fluor kugirango isimbuze atome zose za hydrogène muri polyethylene.Ibi bikoresho birwanya aside, alkalis, hamwe nudukoko dutandukanye twinshi, kandi ntibishobora gukemuka mumashanyarazi yose.Muri icyo gihe, PTFE ifite ibiranga ubushyuhe bwo hejuru, kandi coefficente yayo yo guterana ni mike cyane, bityo irashobora gukoreshwa nkuburyo bwo gusiga amavuta, kandi nayo yabaye igipfundikizo cyiza kumurongo wimbere wibikono bidafite inkoni. n'imiyoboro y'amazi
Ibicuruzwa bikoreshwa cyane cyane kubicuruzwa bikurikira:
PTFE, FEP, PFA, ETFE, AF, NXT, FFR.
PTFE: PTFE (polytetrafluoroethylene) igifuniko kitari inkoni irashobora gukoreshwa ubudahwema kuri 260°C, hamwe nubushyuhe ntarengwa bwo gukoresha ubushyuhe bwa 290-300°C, coefficente yo hasi cyane, irwanya kwambara neza kandi ihagaze neza.
FEP: FEP (fluorine etylene propylene copolymer) idafite inkoni irashonga kandi iratemba kugirango ikore firime idahwitse mugihe cyo guteka.Ifite imiterere ihamye yimiti nibiranga ibintu bidasanzwe.Ubushyuhe ntarengwa bwo gukoresha ni 200℃.
PFA: PFA (ifumbire ya perfluoroalkyl) idafite inkoni irashonga kandi itemba mugihe cyo guteka kugirango ikore firime idahwitse nka FEP.Ibyiza bya PFA nuko ifite ubushyuhe bwo hejuru bwo gukoresha ubushyuhe bwa 260°C, gukomera no gukomera, kandi birakwiriye cyane cyane gukoreshwa muburyo bwo kurwanya imiti no kurwanya imiti mugihe cy'ubushyuhe bwinshi.
PTFE (Polytetrafluoroethene) ni ibikoresho bya polymeriki ya syntetique ikoresha fluor kugirango isimbuze atome zose za hydrogène muri polyethylene.Ibi bikoresho birwanya aside, alkalis, hamwe nudukoko dutandukanye twinshi, kandi ntibishobora gukemuka mumashanyarazi yose.Muri icyo gihe, umuyoboro wa ptfe ufite ibiranga ubushyuhe bwo hejuru, kandi coefficente yacyo yo guterana ni mike cyane, ku buryo ishobora gukoreshwa mu gusiga amavuta, kandi ikaba yaranabaye igifuniko cyiza kuri woks yoroshye-isukuye hamwe nu miyoboro y'amazi.Irashobora gukoreshwa muburyo bwo kurwanya ruswa, kurwanya ubushyuhe bwo hejuru no hasi, hamwe no kurwanya ruswa.Ikoreshwa mubidukikije bikaze nko gusiga amavuta, ubwubatsi, ibikoresho bya elegitoroniki, ibikoresho by'amashanyarazi, hamwe nindege.
Ibiranga ibicuruzwa
1 resistance Kurwanya ubushyuhe buke kandi buke: ingaruka nke kubushyuhe, ubushyuhe bwagutse, ubushyuhe bukoreshwa -65 ~ 260 ℃.
2 、 Kudafatana: Ibintu hafi ya byose ntabwo bihujwe na firime ya PTFE.Filime yoroheje cyane nayo yerekana imikorere myiza yo kutivanga.2. Kurwanya ubushyuhe: firime ya PTFE ifite ubushyuhe bwiza kandi irwanya ubushyuhe buke.Irashobora kwihanganira ubushyuhe bwo hejuru bugera kuri 300 ° C mugihe gito, kandi muri rusange irashobora gukoreshwa ubudahwema hagati ya 240 ° C na 260 ° C.Ifite ubushyuhe bukomeye.Irashobora gukora ku bushyuhe bukonje nta gushiramo kandi ntishonga ku bushyuhe bwinshi.
3 Umutungo wo kunyerera: firime ya PTFE ifite coefficient yo hejuru yo guterana.Coefficient de fraux ihinduka iyo umutwaro urimo kunyerera, ariko agaciro kari hagati ya 0.05-0.15.
4 resistance Kurwanya ubuhehere: Ubuso bwa firime ya PTFE ntabwo ifata amazi namavuta, kandi ntabwo byoroshye gukomera kubisubizo mugihe cyibikorwa byo gukora.Niba hari umwanda muto, uhanagure.Igihe gito cyatakaye, uzigama amasaha yakazi no kunoza imikorere.
5 resistance Kwambara birwanya: Ifite imbaraga zo kwihanganira kwambara munsi yumutwaro mwinshi.Munsi yumutwaro runaka, ifite ibyiza bibiri byo kurwanya kwambara no kutivanga.
6 resistance Kurwanya ruswa: PTFE ntishobora kwangirika n’imiti, kandi irashobora kwihanganira aside zose zikomeye (harimo na aqua regia) hamwe na okiside ikomeye usibye ibyuma bya alkali byashongeshejwe, itangazamakuru rya fluor na hydroxide ya sodium iri hejuru ya 300 ° C.Uruhare rwo kugabanya imiti hamwe nudukoko twinshi dushobora kurinda ibice ubwoko ubwo aribwo bwose bwangirika
umutungo wa shimi
1 ulation Gukingira: Ntabwo byatewe nibidukikije ninshuro, kurwanya amajwi birashobora kugera kuri 1018 ohm · cm, igihombo cya dielectric ni gito, kandi voltage yameneka ni ndende.
2 resistance Kurwanya ubushyuhe buke kandi buke: ingaruka nke kubushyuhe, ubushyuhe bwagutse, ubushyuhe bukoreshwa -190 ~ 260 ℃.
3 、 Kwisiga amavuta: Ifite coefficient ntoya yo guterana muri plastiki kandi ni ibikoresho byiza bitarimo amavuta.
4 Ubuso budakomera: ibikoresho bizwi ntibishobora kwizirika ku buso, ni ibintu bikomeye bifite ingufu nkeya zo hejuru.
5 resistance Kurwanya ikirere, kurwanya imishwarara no gutwarwa gake: guhura nigihe kirekire nikirere, ubuso n'imikorere ntibigihinduka.
6 、 Kudakongoka: Indangagaciro ya ogisijeni iri munsi ya 90.
7 、 PTFE ikoreshwa cyane mu nganda zisaba kurwanya ubushyuhe bwinshi no kwiyegereza cyane.Acide ikomeye cyane ya acide-fluoroantimonic irashobora kandi gukoreshwa mukubungabunga
Agace gasaba ibicuruzwa
Polytetrafluoroethylene irashobora gushirwaho mugusunika cyangwa gusohora;irashobora kandi gukorwa muri firime hanyuma igacibwa muri kaseti ya PTFE yashizwemo mugihe ikoreshejwe insinga z'ubushyuhe bwo hejuru.Ikoreshwa mukubyara insinga nyinshi kandi bigakorwa muburyo bwo gukwirakwiza amazi.Irashobora gukoreshwa mugutwikira, gutera akabariro cyangwa gukora fibre.
Polytetrafluoroethylene ikoreshwa cyane mu nganda nk'ingufu za kirimbuzi, ingabo z’igihugu, icyogajuru, ibikoresho bya elegitoroniki, amashanyarazi, imiti, imashini, ibikoresho, metero, ubwubatsi, imyenda, kuvura ibyuma, imiti, ubuvuzi, ibiryo, metallurgie no gushonga, n'ibindi. ibikoresho, ibikoresho bikingira, ibirwanya anti-inkoni, nibindi bituma biba ibicuruzwa bidasimburwa.
PTFE hoseifite ibintu byiza cyane byuzuye, birwanya ubushyuhe bwo hejuru, birwanya ruswa, bitari inkoni, kwisiga, ibintu byiza bya dielectric, hamwe na coeffisiyeti yo hasi cyane.Ikoreshwa nka plastiki yubuhanga, irashobora gukorwa mubituba bya PTFE, inkoni, umukandara, amasahani, firime, nibindi. Mubisanzwe bikoreshwa mumiyoboro irwanya ruswa, kontineri, pompe, valve, radar, ibikoresho byitumanaho ryinshi, ibikoresho bya radio, radomes, nibindi nibisabwa cyane.Wongeyeho icyuzuzo cyose gishobora kwihanganira ubushyuhe bwa polytetrafluoroethylene, imiterere yubukanishi irashobora kunozwa cyane.Mugihe kimwe, indi mico myiza ya PTFE irabungabunzwe.Ubwoko bwuzuye bwuzuyemo ibirahuri, ibyuma, oxyde yicyuma, grafite, molybdenum disulfide, fibre karubone, polyimide, EKONOL, nibindi. Kurwanya kwambara no kugabanya agaciro ka PV birashobora kwiyongera inshuro 1000
