PTFE, FEP na PFA nibyo bizwi cyane kandi bisanzwe bya fluoroplastique.Ariko, ni ubuhe buryo butandukanye?Menya impamvu fluoropolymers aribikoresho byihariye, kandi fluoroplastique ikwiranye nibisabwa.
Imiterere yihariye ya fluoroplastique
Fluoropolymers yishimira ibintu byinshi bidasanzwe bituma ikoreshwa muburyo bwubuvuzi, ibinyabiziga, amashanyarazi ndetse no murugo, nibindi.
Fluoroplastique ifite ibintu bikurikira:
1.Ubushyuhe bukabije bwo gukora
2.Nta nkoni iranga
3.Gabanya ubuso bwo hejuru
4.Kurwanya cyane imiti nu mashanyarazi
5.Kurwanya amashanyarazi menshi
Fluoroplastike itandukanye yishimira itandukaniro rito, harimo ubushyuhe bwakazi butandukanye, kandi burakwiriye mubikorwa bitandukanye.Niba uhisemo neza, fluoropolymers irashobora gutanga igiciro cyiza ninyungu zo gukora.
Inyungu za PTFE
PTFE, cyangwa Polytetrafluoroethylene, ni sekuru wa fluoroplastique yose.Yavumbuwe n'umuhanga Roy J. Plunkett mu 1938, PTFE ni fluoropolymer idasanzwe kandi yerekana imikorere myiza mubijyanye n'ubushyuhe, imiti irwanya imiti ndetse n'ibidafite inkoni.
Usibye kwishimira imiterere yihariye ya fluoroplastique, PTFE iratandukanye ifite inyungu zikurikira:
1.Ibiciro byiza: igipimo cyimikorere
2.Ubushyuhe bukomeza bwa + 260 ° C - Ubu ni bwo bushyuhe bwo hejuru bwo gukora kuri fluoroplastique
3.Kurwanya imiti hafi ya yose
4.Byinshi bidafite inkoni (ndetse na gecko yatembera kuri PTFE)
5.Ibara risobanutse
Ingaruka nyamukuru ya PTFE nuko idashonga mubyukuri iyo ishyushye bityo bikaba bigoye kuyitunganya.Ubuhanga budasanzwe burakenewe kubumba, gusohora no gusudira iyi fluoropolymer.
Bitewe nimiterere yihariye, PTFE nibyiza mubisabwa mugukoresha amashanyarazi no kurinda ibikoresho bya elegitoroniki.
Turi abanyamwuga bakoraumuyoboro， Niba ufite ikibazo, ushobora kutwandikira!
Inyungu za FEP
FEP, cyangwa Fluoroethylenepropylene, ni verisiyo ishonga ya PTFE.FEP ifite ibintu bisa cyane na PTFE, ariko ifite ubushyuhe buke bwo gukora bwa + 200 ° C.Ariko, FEP irashobora gutunganywa byoroshye kandi irashobora gusudwa byoroshye kandi ikongera kubumbabumbwa muburyo bworoshye.
Nku gutunga ibintu byihariye bya fluoroplastique, FEP yishimira izi nyungu:
1. Gusudira no kongera kubumba ubushobozi
2.Gukoresha ubushyuhe bwakazi -200 ° C kugeza + 200 ° C - FEP ikomeza guhinduka mubushyuhe bwa kirogenike
3.Kurwanya byimazeyo imiti na UV
4.Bio-ihuza
5. Ibara risobanutse
Bitewe nizi nyungu, kugabanuka kwa FEP bifite ubushyuhe buke kandi birashobora kugabanuka neza hejuru yibikoresho byubushyuhe nta bwoba bwo kwangiza.Nkigisubizo, FEP nibyiza mugukwirakwiza ibikoresho byamashanyarazi byoroshye.
Inyungu za PFA
PFA, cyangwa Perfluoralkoxy, ni ubushyuhe bwo hejuru bwa FEP.PFA ifite imitungo isa na FEP ariko irashobora gukoreshwa mubushyuhe bwakazi bugera kuri + 260 ° C mugihe hasigaye gushonga-gutunganywa, bitewe nubwiza buke bwo gushonga kuruta PTFE.
Usibye kwishimira imiterere yihariye ya fluoropolymers, PFA iratandukanye no kugira inyungu zikurikira:
Ubushyuhe bukomeza bwo gukora bwa + 260 ° C - Ubu ni bwo bushyuhe bwo hejuru bwo gukora kuri fluoroplastique
1.Gusudira no kongera kubumba ubushobozi
2.Ibirwanya neza
3.Imiti idasanzwe irwanya imiti, ndetse no ku bushyuhe bwo hejuru
4.Bio-ihuza
5.Icyiciro cyo hejuru cyera kirahari
6.Ibara risobanutse
Ingaruka nyamukuru ya PFA nuko ihenze kuruta PTFE na FEP.
PFA nibyiza kubisabwa bisaba urwego rwohejuru rwo hejuru, imiti irwanya imiti nubushyuhe bwo hejuru.Iyi fluoroplastique ikoreshwa cyane mubuvuzi bwubuvuzi, guhanahana ubushyuhe, ibiseke byayobora igice, pompe na fitingi, hamwe na valve.
Hano kuriBesteflonturi inzobere mugutanga udushya twa fluoropolymer kubisabwa bya tekiniki.Shakisha byinshi kuri tweIbicuruzwa bya Fluoroplastique.
