Iterambere rya Polytetrafluoroethylene (PTFE) - kuva ku gicuruzwa cyihariye gikoreshwa gusa mu bikorwa by'agaciro kanini kugeza ku gikenewe rusange ryagiye rikorwa buhoro buhoro.
Ariko, mu myaka makumyabiri ishize ikoreshwa rya PTFE risa n’aho ryarenze urugero, bituma rishobora kugurishwa mu nganda zisaga 200, ku bakoresha no mu buvuzi. Nubwo impapuro, inkoni, irangi n'ibice byaryo ari byo bikurura isoko ry'ibicuruzwa bya PTFE, umuyoboro wa PTFE n'umuyoboro wa PTFE ubu biri kugaragara nk'agace k'ingenzi gakuramo.
Porogaramu za PTFE tube
Ikoreshwa ryaUmuyoboro wa PTFEyakwirakwiriye mu bikorwa bitandukanye birimo imodoka, imiti, amashanyarazi n'ubuvuzi. Imbonerahamwe ya 1 igaragaza imiterere y'ingenzi igaragaza uburyo PTFE ikora neza, mu gihe Ishusho ya 1 igaragaza ikoreshwa ryayo mu nzego zitandukanye.
Mu mikoreshereze y'imodoka, ubushobozi bwa PTFE bwo kwihanganira ubushyuhe burenze 250°C butuma iba nziza cyane mu gutwara amazi mu bushyuhe bwinshi.
Mu buvuzi,Umuyoboro wa PTFEirakenewe cyane bitewe n'uburyo ikoresha amavuta menshi kandi ikaba idakora neza. Catheters zikoresha umuyoboro wa PTFE zishobora gushyirwa mu mubiri w'umuntu nta bwoba bwo kugira ingaruka cyangwa gushwanyagurika ku bice by'umubiri.
Mu ikoreshwa rya shimi – harimo na laboratwari – PTFE ni nziza cyane gusimbura ikirahure bitewe nuko kidapfa kandi kidapfa.
Mu mikoreshereze y'amashanyarazi, imiterere myiza ya dielectric ya PTFE ya virgin ituma ikoreshwa neza mu gukingira insinga zifite amashanyarazi menshi.
Ubwoko bw'umuyoboro wa PTFE
Bitewe n'uburyo ikoreshwa, umuyoboro wa PTFE ugabanyijemo ibyiciro bitatu binini - buri kimwe gisobanurwa n'umurambararo w'umuyoboro n'ubugari bw'urukuta (reba Imbonerahamwe ya 2).
Ndetse no mu byiciro, umuyoboro wa PTFE wifashisha uburyo butandukanye, buri kimwe cyemerera gukoreshwa mu buryo butandukanye (reba Imbonerahamwe ya 3):
Umuyoboro wa PTFE uri ku isoko ry'ibikoresho by'ubuvuzi
Muri rusange, umuyoboro muto wa spaghetti ukoreshwa mu buvuzi. Ikoreshwa rya PTFE muri aka gace rishingiye ku bintu bibiri by'ingenzi: amavuta n'ubushobozi bwo guhuza ibintu. Fluoropolymers zigaragaza amavuta meza cyane ugereranije n'izindi plastiki. PTFE ni polymeri irusha izindi amavuta amavuta, ifite coefficient of friction ya 0.1, ikurikirwa na fluorinated ethylene propylene (FEP), ifite 0.2. Izi polymeri ebyiri zigaragaza igice kinini cy'umuyoboro wose wa fluoropolymer ukoreshwa mu bikoresho by'ubuvuzi.
Kuba polymer iyo ari yo yose ikoreshwa mu gikoresho cyo kwa muganga ihura n’ibibazo ni ikibazo gihangayikishije. PTFE irakomeye muri uru rwego kandi ifite amateka maremare yo gukoreshwa mu mubiri. Fluoropolymer zo mu rwego rw’ubuvuzi zigomba kuzuza ibisabwa mu isuzuma rya USP Class VI na ISO 10993. Birumvikana ko isuku yo gutunganya ibikoresho nayo ari ikintu cy’ingenzi.
Mu myaka 18 ishize, Besteflon yakomeje kwibanda ku gukora imiyoboro ya PTFE na PTFE. Nk'abambere mu bijyanye no gukora fluoroplastics, dukurikirana serivisi nziza kandi nyuma yo kugurisha. Niba wifuza gutangira guhindura umuyoboro wa PTFE kugira ngo ukoreshe neza, twandikire!
