Imyenda ya PTFE , izwi kandi ku izina rya Teflon yometseho umwenda cyangwa umwenda wa PTFE, ni ibintu bidasanzwe byerekana kurwanya bidasanzwe ubushyuhe no kwangirika. Uku guhuza ibintu bidasanzwe guturuka kubiranga PTFE (polytetrafluoroethylene) hamwe no guhuza hamwe nimyenda yo mu rwego rwo hejuru. Ipitingi ya PTFE ikora inzitizi idahwitse ihanganira ubushyuhe bukabije bugera kuri 500 ° F (260 ° C) kandi ikarwanya igitero cy’imiti kiva mu bintu byinshi byangiza. Imiterere ya molekile yayo, igizwe na karubone-fluor ikomeye, itanga ubushyuhe budasanzwe bwumuriro hamwe nubusembure bwimiti, bigatuma imyenda ya PTFE ikomeza kuba inyangamugayo no gukora mubidukikije bikabije aho ibindi bikoresho byangirika vuba.

Ubumenyi Bwihishe inyuma ya PTFE
Imiterere ya molekulari hamwe nubushyuhe bwumuriro
Ubushyuhe budasanzwe bwa PTFE bushinze imizi muburyo bwihariye bwa molekile. Polymer igizwe numugongo wa karubone hamwe na atome ya fluor ihujwe cyane nayo. Iyi gahunda ikora molekile ihamye cyane isaba imbaraga zikomeye zo gusenyuka. Imiyoboro ya karubone-fluor iri mubikomeye muri chimie organic, bigira uruhare mubushobozi bwa PTFE bwo gukomeza imiterere n'imiterere yubushyuhe bwinshi.
Iyo ihuye nubushyuhe, molekile ya PTFE ntishobora guhita ikora cyangwa ngo ibore. Ahubwo, bakomeza iboneza ryabo, bemerera ibikoresho kurwanya ubushyuhe bwumuriro. Uku gushikama ni ingenzi cyane mubikorwa mu nganda nko mu kirere no mu modoka, aho ibice bishobora guhura n’imihindagurikire y’ubushyuhe bukabije.
Ubushyuhe buke
Ikindi kintu kigira uruhare muri Teflon yambitswe imyenda yubushyuhe ni ubushyuhe buke bwumuriro. Uyu mutungo bivuze ko ubushyuhe butoroha byoroshye binyuze mubikoresho. Nkigisubizo, imyenda isize PTFE irashobora gukora nkimashanyarazi ikora neza, ikarinda hejuru yubutaka cyangwa ibice byubushyuhe bwinshi.
Mu nganda, ibi biranga bifite agaciro cyane. Kurugero, mu nganda zitunganya ibiryo, imikandara ya convoyeur ya PTFE irashobora gukoresha ibicuruzwa bishyushye bitarinze kohereza ubushyuhe bukabije kumashini cyangwa guhungabanya ubusugire bwibintu bitwarwa.
Ingingo yo gushonga
PTFE ifite ahantu hanini cyane gushonga ya 327 ° C (620 ° F). Ubu bushyuhe bwo hejuru bwo gushonga butuma imyenda ya PTFE isize kugirango igumane imiterere ihamye hamwe nibikorwa bikora mubidukikije aho izindi polymers nyinshi zoroha cyangwa zishonga.
Ahantu ho gushonga ni ngombwa cyane mubikorwa byinganda nko guhimba ibyuma cyangwa gusudira, aho imyenda ya PTFE ishobora gukoreshwa mu mwenda ukingira cyangwa imyenda. Ibi bikoresho birashobora kwihanganira guhura nigihe gito cyashongeshejwe cyuma cyangwa ubushyuhe bukabije bitabangamiye imiterere yabyo yo kubarinda.
Uburyo bwa PTFE bwo Kurwanya Kurwanya
Ubusembwa bwa Shimi
PTFE idasanzwe yo kurwanya ruswa iterwa ahanini nubusembure bwimiti. Imiyoboro ikomeye ya karubone-fluor muri molekile ya PTFE ituma irwanya cyane imiti yimiti. Ubu budahangarwa bivuze ko imiti myinshi, harimo acide na base ikomeye, idashobora gusenyuka byoroshye cyangwa kubyitwaramo na PTFE.
Mu nganda zikoreshwa mu nganda, uyu mutungo ni uw'agaciro. Imyenda ya PTFE ishobora gukoreshwa mu nganda zitunganya imiti, muri laboratoire, ndetse n’ibindi bidukikije aho usanga ibintu byangirika. Ipitingi ikora nk'inzitizi ikingira, irinda umwenda wimbere cyangwa substrate guhura n’imiti ishobora kwangiza.
Ubuso butagaragara
Imiterere idafatika ya PTFE igira uruhare runini mukurwanya ruswa. Ingufu nkeya zubutaka bwa PTFE bivuze ko ibintu byinshi, harimo namazi yangirika, bigira ikibazo cyo kwizirika hejuru yacyo. Uyu mutungo ntutuma gusa umwenda utwikiriye PTFE woroshye gusukurwa ahubwo unarinda ibintu byangirika gukomeza guhuza igihe kirekire nibikoresho.
Mubisabwa nko kuyungurura inganda cyangwa kubika imiti, ubu bwiza butari inkoni bufasha gukumira ikwirakwizwa ryibisigazwa byangirika bishobora kwangiza ibikoresho mugihe. Yorohereza kandi uburyo bworoshye bwo kubungabunga no gukora isuku, ikongerera igihe cyibikoresho bya PTFE.
Kutemerwa kubintu byinshi
Imiterere ya PTFE yuzuye ikora inzitizi itemewe kubintu byinshi. Uku kudahinduka ni ingenzi cyane mu kurwanya ruswa, kuko irinda ibintu byangirika kwinjira mu bikoresho no kugera ku nzego cyangwa munsi y’ubutaka.
Mu nganda nko gukora imiti cyangwa gutunganya amazi mabi, aho usanga guhura nibintu bitandukanye byangirika, imyenda isize PTFE ikora nk'imirongo ikingira cyangwa inzitizi. Birashobora gukoreshwa kumurongo wa tanki, imiyoboro, cyangwa ibindi bikoresho, bitanga ingabo irambye yo kurwanya ibitero byangirika.
Porogaramu Gukoresha Ubushyuhe bwa PTFE no Kurwanya Ruswa
Ibikoresho byo gutunganya inganda
Imyenda ya PTFE isanga ikoreshwa cyane mubikoresho bitunganya inganda aho ubushyuhe ndetse no kurwanya ruswa ari ngombwa. Bikunze gukoreshwa nkumukandara wa convoyeur munganda zitunganya ibiryo, aho zishobora kwihanganira ubushyuhe bwinshi bwo guteka no kurwanya iyangirika rya acide yibiribwa cyangwa imiti isukura. Mu nganda zitunganya imiti, imyenda isize PTFE ikora nk'imiterere ihindagurika ya reaktor, ibigega byo kubikamo, hamwe n’amazu yimurwa, bikarinda imiti myinshi yangiza imiti y’ubushyuhe bukabije.
Kuramba no kwizerwa byibikoresho bya PTFE muri izi porogaramu bigira uruhare mu kongera ibikoresho kuramba, kugabanya amafaranga yo kubungabunga, no kunoza imikorere. Kurugero, mubikorwa bya farumasi, imyenda ya PTFE ikozwe muri sisitemu yo kuyungurura irashobora gukoresha ubushyuhe bwinshi hamwe n’umuti ukabije, bigatuma ubuziranenge bwibicuruzwa ndetse nubwiza buhoraho.
Ikirere hamwe na Porogaramu zikoresha imodoka
Inganda zo mu kirere n’imodoka zishingiye cyane cyane ku mwenda wa PTFE kubera guhuza kwihariye kw’ubushyuhe no kurwanya ruswa. Mu ndege, ibyo bikoresho bikoreshwa mu gucana peteroli na hydraulic, aho bigomba kwihanganira ubushyuhe bwinshi kandi bikarwanya iyangirika ry’ibikomoka ku ndege n’amazi ya hydraulic. Imyenda ya PTFE isanga kandi ikoreshwa mubice bya moteri nkibipfundikizo bikingira cyangwa bikingira, aho bishobora kurwanya ubushyuhe n’imodoka.
Mu rwego rw’imodoka, imyenda isize PTFE ikoreshwa muburyo butandukanye butari munsi ya hood, nkingabo zikingira ubushyuhe hamwe ningingo zoroshye. Ubushobozi bwabo bwo guhangana nubushyuhe bwo hejuru mugihe barwanya ruswa ituruka kumavuta ya moteri, ibicurane, hamwe na gaze ya gaze ituma biba ingirakamaro muri ibi bidukikije bisaba. Gukoresha ibikoresho bisize PTFE bigira uruhare mu kunoza imikorere yimodoka, kuramba, numutekano.
Gukoresha Ubwubatsi nubwubatsi
Inganda zubaka zakiriye imyenda ya PTFE kugirango irambe kandi irwanya ibidukikije. Ibi bikoresho bikunze gukoreshwa mubwubatsi bubi, aho bigizwe nububiko bworoshye, butarwanya ikirere. Ubushuhe bugaragaza ubushyuhe bwa PTFE bifasha kugabanya kwiyongera kwizuba mu nyubako, bigira uruhare mu gukoresha ingufu.
Mubisobanuro byihariye, PTFE itwikiriye imyenda ikoreshwa nkigikorwa cyo kwagura ibifuniko mubiraro ninyubako nini. Hano, ntibagomba kurwanya gusa kwangirika kwikirere gusa ahubwo banashyuha nubushyuhe buterwa no guhora hamwe no guterana amagambo. Kuramba hamwe nibisabwa bike kubikoresho bisize PTFE bituma bahitamo neza-kubikoresho byububiko, akenshi bimara imyaka mirongo hamwe no guteshwa agaciro.
Umwanzuro
PTFE yambitswe imyenda idasanzwe yo kurwanya ubushyuhe no kwangirika bituruka ku miterere yihariye ya molekile n'imiterere. Imiyoboro ikomeye ya karubone-fluor, ubushyuhe buke bwumuriro, hamwe nubusembwa bwa chimique ya PTFE birema ibintu bishobora kwihanganira ubushyuhe bukabije nibidukikije bikabije. Uku guhuza imitungo ituma imyenda ya PTFE itwikiriye ntangere muburyo butandukanye bwinganda, ikirere, hamwe nubwubatsi. Mugihe inganda zikomeje gushimangira imipaka yimikorere yibikoresho, imyenda isize PTFE ikomeza kuba kumwanya wambere, itanga ibisubizo byizewe kubidukikije bisabwa cyane.
