Ubwihindurize bwa Polytetrafluoroethylene (PTFE) - kuva ku bicuruzwa byiza byakoreshejwe gusa mu gaciro gakoreshwa cyane kugeza kubisabwa byingenzi byabaye buhoro buhoro.
Nyamara, mu myaka 20 ishize imikoreshereze ya PTFE isa nkaho yarenze imbaga nyamwinshi, ituma ishobora kuba ingirakamaro mu bucuruzi mu nganda zirenga 200, inganda, abaguzi n’ubuvuzi.Mugihe kandi impapuro, inkoni, ibifuniko hamwe nibigize ibice byinshi byisoko ryibicuruzwa bya PTFE, umuyoboro wa PTFE na hose ya PTFE ubu bigaragara nkigice cyingenzi cyo gukura.
Porogaramu ya PTFE
Ikoreshwa ryaUmuyoboro wa PTFEyakwirakwiriye mubikorwa bitandukanye birimo ibinyabiziga, imiti, amashanyarazi nubuvuzi.Imbonerahamwe 1 irerekana ibintu byingenzi byerekana uburyo butandukanye bwa PTFE, mugihe igishushanyo 1 cyerekana imikoreshereze yacyo mubice bitandukanye.
Mubikorwa byimodoka, ubushobozi bwa PTFE bwo guhangana nubushyuhe burenze 250 ° C bituma iba umukandida mwiza wo kohereza amazi menshi.
Mubisabwa mubuvuzi,Umuyoboro wa PTFEirakenewe cyane kubera amavuta nubusembure bwimiti.Catheters ikoresha umuyoboro wa PTFE irashobora kwinjizwa mumubiri wumuntu udatinya kubyitwaramo cyangwa gukuramo ibice byose byumubiri.
Mubikoresho bya chimique - harimo na laboratoire - PTFE nigisimburwa cyiza cyikirahure bitewe nubusembure bwacyo.
Mumashanyarazi, ibikoresho byiza bya dielectrici yisugi PTFE ituma bikwiranye no gukingira insinga nini za voltage.
Ubwoko bwa PTFE
Ukurikije porogaramu, umuyoboro wa PTFE ugabanijwemo ibyiciro bitatu bigari - buri kimwe gisobanurwa na diameter ya tube hamwe nubunini bwurukuta (reba Imbonerahamwe 2).
Ndetse no mubyiciro, umuyoboro wa PTFE utanga uburyo butandukanye, buri kimwe cyemerera porogaramu zitandukanye (reba Imbonerahamwe 3):
Umuyoboro wa PTFE ku isoko ryibikoresho byubuvuzi
Muri rusange, diameter ntoya spaghetti ikoreshwa mubisabwa mubuvuzi.Imikoreshereze ya PTFE muri kano karere yibanze kumitungo ibiri yingenzi: amavuta na biocompatibilité.Fluoropolymers yerekana amavuta meza cyane ugereranije nandi plastiki.PTFE ni polymer yamavuta menshi aboneka, hamwe na coefficient de friction ya 0.1, ikurikirwa na fluorine etylene propylene (FEP), hamwe na 0.2.Izi polimeri zombi zerekana ubwinshi bwa fluoropolymer tube ikoreshwa mubikoresho byubuvuzi.
Biocompatibilité ya polymer iyo ari yo yose ikoreshwa mubikoresho byubuvuzi ni impungenge zigaragara.PTFE nziza muri kano karere kandi ifite amateka maremare yo gukoresha vivo.Floropolymers yo mu rwego rwubuvuzi igomba kuba yujuje ibyangombwa byo gupima USP Icyiciro cya VI na ISO 10993.Nibyo, gutunganya isuku nabyo ni ikintu cyingenzi.
Mu myaka 18 ishize, Besteflon ikomeje kwibanda ku gukora PTFE Tubes na PTFE hose.Nka bambere mubijyanye no gukora fluoroplastique, dukurikirana serivise nziza na nyuma yo kugurisha.Niba wifuza gutangira gutunganya umuyoboro wa PTFE kubisabwa byihariye, nyamuneka twandikire!
