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. Kurwanya Vacuum birashobora gukoreshwa mugihe cyimyuka, mugukora imiti, akenshi biterwa no gukonja, gusohora igihe kirekire, pompe ya pompe ntabwo ihujwe nigikorwa cyibintu byatewe na leta ya vacuum yaho.
3. Kurwanya umuvuduko mwinshi mukoresha urwego rwubushyuhe, birashobora kwihanganira kugera kuri 3MPA yo gukoresha igitutu
4. Kurwanya anti-permeation ya resin nziza ya PTFE, binyuze mumurongo wateye imbere murwego rwinshi, ubunini buhagije bwurwego rwa PTFE, kuburyo ibicuruzwa bifite anti-permeability
5. Muri rusange uburyo bwo kubumba no gucumura kumurongo bikemura ikibazo cyo kwaguka gukonje nubukonje bwibyuma na fluor, bigatuma bigera no kwaguka hamwe
6. Ibipimo bisanzwe byemejwe, cyane cyane kumiyoboro n'ibikoresho bikoreshwa mu miyoboro ya shimi, bihinduranya cyane kandi bitanga uburyo bworoshye bwo kwishyiriraho no kubika ibikoresho.
Ibyiza byo kurwanya ruswa:
1. Kurwanya ubushyuhe bwinshi {koresha ubushyuhe bwa dogere 260.
2. Acide ikomeye na alkali irwanya (pH 1 ~ 14)
3. Kwifata neza pressure igitutu kibi gishobora kugera 0.09MPa, ingaruka za vacuum.
4. Ubuzima bumara igihe kirekire {Mubihe bisanzwe birashobora gukoreshwa mumyaka 8 kugeza 10, kandi igihe cya garanti gisezeranijwe kuba umwaka 1.
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 fluide, irashobora kurwanya ibitangazamakuru bya chimique hafi ya byose hamwe na aside nitricike yibanze hamwe na aqua regia ruswa, irashobora gukora kuri 230 ℃ - 250 ℃ ubushyuhe mugihe kirekire.Icyuma cya polyvinylidene fluoride cyangwa ikindi cyiciro cya vinylidene fluoride icyiciro cya compte, kugeza halogen, hydrocarbone ya halogene, okiside ikomeye, aside itetse, alkali, ibishishwa bitandukanye byumubiri bifite imbaraga zo kurwanya ruswa, ariko ntibisukamo aside sulfurike, aside irike ya sulfurike na aside nitricike, 90 ℃ hejuru ya ketone, ester, amine nubushyuhe bwo hejuru sulphonated agent ruswa.
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.
