PTFE, FEP na PFA ni byo binyabutabire bizwi cyane kandi bikunze gukoreshwa. Ariko se koko itandukaniro ryabyo ni irihe? Menya impamvu fluoropolymers ari ibikoresho bidasanzwe, n'ubwoko bwa fluoroplastic bukwiriye gukoreshwa.
Imiterere yihariye ya fluoroplastics
Fluoropolymers zifite imiterere itandukanye idasanzwe ituma zikoreshwa mu buvuzi, mu modoka, mu by'amashanyarazi no mu ngo, n'ibindi.
Fluoroplastic ifite imiterere ikurikira:
1.Ubushyuhe buri hejuru cyane mu kazi
2. Ikiranga kudafatana
3.Ubuso bworoshye bwo gukururana
4. Ubudahangarwa bukomeye cyane ku miti n'ibinyabutabire
5. Ubudahangarwa bw'amashanyarazi buri hejuru cyane
Udupira twa fluoroplastic dutandukanye dufite itandukaniro rito, harimo n'ubushyuhe butandukanye mu kazi, kandi dukwiriye gukoreshwa mu buryo butandukanye. Iyo dutoranijwe neza, fluoropolymers zishobora gutanga inyungu ku giciro cyiza no ku mikorere myiza.
Ibyiza bya PTFE
PTFE, cyangwa Polytetrafluoroethylene, ni yo mvange y’uturemangingo twose twa fluoroplastic. Yavumbuwe n’umuhanga mu bya siyansi Roy J. Plunkett mu 1938, PTFE ni yo fluoropolymer idasanzwe kandi igaragaza imikorere myiza mu bijyanye n’ubushyuhe, kurwanya imiti ndetse n’imiterere idafatana.
Uretse kuba ifite imiterere yihariye ya fluoroplastics, PTFE yitandukanya n'izindi nyungu zikurikira:
1. Igiciro cyiza: igipimo cy'imikorere
2. Ubushyuhe buhoraho bwo gukora bwa +260°C - Ubu ni bwo bushyuhe bwinshi bwo gukora kuri fluoroplastic iyo ari yo yose
3. Kurwanya hafi ya imiti yose
4. Ntibifata cyane (ndetse n'igikoko cyagwa kuri PTFE)
5. Ibara ry'urumuri
Ingorane nyamukuru ya PTFE ni uko idashonga iyo ishyushye bityo ikaba igoye kuyitunganya. Hakenewe ubuhanga budasanzwe kugira ngo iyi fluoropolymer ikoreshwe, ivanwemo kandi isudirwe.
Bitewe n'imiterere yayo idasanzwe, PTFE ni nziza cyane mu bikorwa byo gukingira amashanyarazi no kurinda ibice by'ikoranabuhanga.

Ibyiza bya FEP
FEP, cyangwa Fluoroethylenepropylene, ni verisiyo ya PTFE ishobora gushonga. FEP ifite imiterere isa cyane na PTFE, ariko ifite ubushyuhe buke bwo gukora bwa +200°C. Ariko, FEP ishobora gutunganywa byoroshye kandi ishobora gusukurwa byoroshye no kongera kuyihinduramo imiterere igoye.
Uretse kuba ifite imiterere yihariye ya fluoroplastics, FEP ifite izi nyungu:
1. Gusudira no kongera gukoresha ibikoresho byo gushushanya
2. Ubushyuhe bw'akazi kuva kuri -200°C kugeza kuri +200°C - FEP iguma ihinduka iyo ubushyuhe bukabije
3. Ubudahangarwa bwose ku binyabutabire na UV
4. Bijyanye n'ibinyabuzima
5. Ibara risobanutse neza
Kubera izi nyungu, ubushyuhe bwa FEP bugabanuka buhoro kandi bushobora kugabanuka neza ku bikoresho bishobora kwangirika nta gutinya kwangiza. Kubera iyo mpamvu, FEP ni nziza cyane mu gufunga ibice by'amashanyarazi n'ibikoresho byayo.
Ibyiza bya PFA
PFA, cyangwa Perfluoralkoxy, ni verisiyo y'ubushyuhe bwinshi ya FEP. PFA ifite imiterere isa na FEP ariko ishobora gukoreshwa ku bushyuhe bugera kuri +260°C mu gihe ikomeza gushonga, bitewe n'ubushyuhe buke bwo gushonga ugereranyije na PTFE.
Uretse kuba ifite imiterere yihariye ya fluoropolymers, PFA yitandukanya n'izindi nyungu zikurikira:
Ubushyuhe buhoraho bwo gukora bwa +260°C - Ubu ni bwo bushyuhe bwinshi bwo gukora kuri fluoroplastic iyo ari yo yose
1. Gusudira no kongera gukoresha ubushobozi bwo gutunganya
2. Ubudahangarwa bwiza bwo kwinjira mu kirere
3. Irwanya imiti cyane, nubwo haba hari ubushyuhe bwinshi
4. Bijyanye n'ibinyabuzima
5. Amanota yo kutagira isuku menshi arahari
6. Ibara risobanutse neza
Ingorane nyamukuru ya PFA ni uko ihenze kurusha PTFE na FEP.
PFA ni nziza cyane ku bikoresho bisaba ubuziranenge buri hejuru, ubushobozi bwo kurwanya imiti n'ubushyuhe bwinshi mu kazi. Iyi fluoroplastic ikoreshwa cyane mu miyoboro y'ubuvuzi, mu byuma bihindura ubushyuhe, mu dusanduku twa semi-conductor, mu mapompo n'ibikoresho, no mu byuma bigabanya ubushyuhe.
