Ibyiza byo mu rwego rwo hejuru Ibyuma bya PTFE byashyizwe kumurongo

Ibikoresho bya Teflon byashyizwe ku murongo ni ibyuma bya PTFE byo mu bwoko bwa pisitike, bishobora kurwanya aside ikomeye na alkali.
Gutangiza imiyoboro: PTFE yatondekanye ibyuma birwanya ruswa nyuma yimyaka myinshi ikoreshwa, bigira ingaruka itaziguye mubuzima bwa serivisi kandi ibintu bihamye ni ubushyuhe, igitutu, itangazamakuru, nibindi, ibikoresho byiza nibikorwa byiterambere bigezweho ni ibyiringiro byiza byibicuruzwa bya PTFE.
Ibiranga
1. Ubushyuhe bwo hejuru mubitangazamakuru bikomeye byangirika, birashobora guhura nikoreshwa ryubushyuhe-dogere 60 ~ 200 dogere, murubu bushyuhe burashobora guhura nibitangazamakuru byose byimiti
2.
3. Kurwanya umuvuduko mwinshi mukoresha ubushyuhe bwubushyuhe, birashobora kwihanganira kugera kuri 3MPA yo gukoresha igitutu
4.
5. Muri rusange uburyo bwo kubumba no gucumura kumurongo bikemura ikibazo cyo kwaguka gashyushye nubukonje bwicyuma na fluor, bigatuma bigera no kwaguka hamwe
6. Ibipimo ngenderwaho byemewe byemejwe, cyane cyane ku miyoboro n’ibikoresho bikoreshwa mu miyoboro y’imiti, bihinduranya cyane kandi bitanga uburyo bworoshye bwo kwishyiriraho n’ibikoresho.
Ibyiza byo kurwanya ruswa:
1. Kurwanya ubushyuhe bwinshi {koresha ubushyuhe bwa dogere 260.
2. Acide ikomeye na anti-alkali (pH 1 ~ 14)
3. Gufata neza cyane pressure igitutu kibi gishobora kugera kuri 0.09MPa, ingaruka za vacuum.
.
5. Kurwanya cyane kwinjira {acide hydrofluoric. Gazi ya Chlorine. Acide ya Bromofluoric hamwe nizindi myuka bifite imbaraga zo kurwanya gucengera
Imikorere:
Imikorere: akazi gaciriritse -100 ℃ ~ -250 ℃
Umuvuduko wo gukora hagati: umuvuduko mwiza: -2.5MPa, kurwanya umuvuduko mubi mubushyuhe bwicyumba 70KPa
Kurwanya ruswa: ibyuma bya polytetrafluoroethylene icyiciro cya compte fitingi, usibye lithium yicyuma gishongeshejwe, potasiyumu, sodium, chlorine trifluoride, ogisijeni trifluoride ku bushyuhe bwinshi, umuvuduko mwinshi wa fluor fluor, irashobora kurwanya ibitangazamakuru hafi ya byose bya chimique hamwe na acide regia ruswa ℃ Icyuma cya polyvinylidene fluoride cyangwa ikindi cyiciro cya fluoride ya vinylidene, kugeza kuri halogene, hydrocarbone ya halogene, okiside ikomeye, aside itetse, alkali, imiti itandukanye yumubiri ifite imbaraga zo kurwanya ruswa, ariko ntabwo ihumeka aside sulfurike, acide ya sulfurike hamwe na acide ya nitric, 90 ℃ hejuru ya ketone, ester.
Ibyiza:
Kurwanya ubushyuhe bwinshi - koresha ubushyuhe bwakazi bugera kuri 250 ℃.
Ubushyuhe buke - ubukanishi bwiza; niyo ubushyuhe bwamanuka kuri -196 ° C, kuramba birashobora gukomeza kuri 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 bwa plastiki iyo ari yo yose.
Amavuta menshi - coefficient yo hasi yo guteranya ibintu byose bikomeye.
Kudafatana - bifite uburemere buke bwo hejuru bwibintu byose bikomeye kandi ntabwo byubahiriza ikintu icyo aricyo cyose.
Ntabwo ari uburozi - ntabwo ari uburozi ku binyabuzima
Gukoresha ibicuruzwa:
Ibyuma bikoreshwa mu byuma bya PTFE: bikwiranye na gaze yangirika cyane hamwe namazi yubushyuhe bwinshi, ubundi bwoko bwibyuma bya pulasitiki hamwe nibikoresho byicyuma ntibikwiye gutwara ibitangazamakuru, ibyuma bya PTFE. Umuyoboro uhuriweho urakoreshwa, icyuma cya polyvinylidene fluoride icyiciro cya compte ikwiranye nogutwara ibitangazamakuru byangirika kubushyuhe bwakazi -40 ℃ ~ +150 ℃.
Ibyuma bitondekanya ibyuma bya PTFE bifatanyirijwe hamwe, ukoresheje uburyo bukomeye bwo gutondekanya umurongo, birwanya umuvuduko mubi na vacuum, kubumba bitagira ikidodo, kiringaniye kandi gikomeye, nta buso bunini. Gukomatanya ntabwo bigwa. Ikoreshwa cyane mumashanyarazi, inganda zimiti, ibikomoka kuri peteroli, kurengera ibidukikije nizindi nganda.
