Ni ubuhe bushyuhe ibikoresho bya PTFE bishobora gukoreshwa?

Isahani ya Tetrafluoroethylene izwi nk'umwami wa plastiki mu rwego rwa plastiki, kandi imikorere yayo ntishoboka na plastiki zisanzwe, bityo rero ikaba isanzwe ikoreshwa ahantu hafite ibidukikije bikaze, nka aside na alkali, itangazamakuru ryangiza n'ubushyuhe bwinshi.None, ni izihe nyungu z'ubuyobozi bwa PTFE?

Ubwa mbere, ifite ubushyuhe bwo hejuru.Kubijyanye no gukoresha ubu urupapuro rwa tetrafluoroethylene, ibikoresho fatizo birashobora kugera kuri 232 ° C, ndetse nubushyuhe bwo hejuru nyuma yo gusubira mu kato bishobora kugera kuri 150 ° C, kandi ubushyuhe bwo gukoresha ni bugari cyane.

Urupapuro rwa PTFE rufite imiterere myiza ya dielectric, imbaraga zidasanzwe za dielectric hamwe no kurwanya arc, gutakaza ingufu za dielectric tangent, hamwe no kurwanya corona nabi.Urupapuro rwa tetrafluoroethylene rufite uburyo bwiza bwo kwinjiza amazi, kutagira ogisijeni, UV hamwe n’ikirere.Imbaraga zidasanzwe zo hanze ntizigeze zihinduka mumyaka itatu ikurikiranye, gusa kuramba kwaragabanutse.Filime ya Teflon hamwe na coatings byinjira mumazi na gaze kubera ubwiza bwabo.PTFE irashobora kuba ikwiranye nubushyuhe bwibidukikije hagati ya dogere 190 na dogere 250.Irashobora gushyuha cyangwa ubukonje butunguranye, cyangwa guhinduranya ubushyuhe n'imbeho nta ngaruka.Usibye gukemura ibibazo by’imiti n’ibikomoka kuri peteroli, impapuro za tetrafluoroethylene zishobora no kugira uruhare mu miti n’imiti.Hano haribintu byinshi bifunga kashe kumasoko uyumunsi, hamwe nibicuruzwa cyangwa ibicuruzwa.Mubyongeyeho, PTFE nayo ikoreshwa cyane mubikoresho bisabwa kashe, kandi ikoreshwa cyane nka Jinxining yuzuza.Uruhare rwurupapuro rwa PTFE ni runini cyane, kubera ko urupapuro rwa PTFE rufite uruhare runini, ibicuruzwa bitandukanye, kandi rukagira uruhare runini mubice bitandukanye no mubice bitandukanye.PTFE irashobora kugaragara ahantu hose mubuzima bwacu.

Icya kabiri, uko ubwoko bwimiti yaba imeze kose, niyo yaba yangirika gute, PTFE irashobora gukoreshwa cyane.Birashobora kuvugwa ko niba urupapuro rwa PTFE rudashobora kuzuza ibisabwa byo kurwanya ruswa, nta bindi bikoresho bya pulasitike bishobora gukoreshwa.Usibye uburyo bwiza bwo kurwanya imiti, imiterere yubukanishi nayo iragaragara cyane, ituma ikwiriye gukoreshwa mugihe gifite ibizunguruka binini kandi byunamye.

Urupapuro rwa PTFE rukoreshwa cyane muri plastiki yubuhanga nkubushyuhe bwo hejuru 260 ℃, ubushyuhe buke -196 ℃, aside irwanya ruswa, kurwanya ikirere no kutagira uburozi.PTFE irashobora kugaragara mubikomoka kuri peteroli, imiti, ubuvuzi, ibikoresho bya elegitoroniki ndetse ninganda zibiribwa.Niba isahani ya PTFE ifite uburozi kandi ifite imbaraga zo kurwanya kwambara, ni ibikoresho byiza byo gufunga.PTFE (Polytetrafluoroethylene, mu magambo ahinnye yitwa PTFE), bakunze kwita "gutwikira inkoni" cyangwa "ibikoresho byoroshye-byoza".Ibi bikoresho bifite ibiranga aside na alkali birwanya no kurwanya imashanyarazi itandukanye, kandi ntibishobora gukemuka mumashanyarazi yose.Muri icyo gihe, isahani ya PTFE ifite ibiranga ubushyuhe bwo hejuru hamwe na coefficient de fraisse nkeya cyane.Usibye gusiga amavuta, uburyo bwo gukora plaque ya PTFE nabwo bwabaye igifuniko cyiza cyo gusukura byoroshye igice cyimbere cyamazi.
