Imyenda ya PTFE , izwi kandi ku izina rya Teflon yometseho imyenda, yahinduye inganda zitandukanye n’imiterere idasanzwe yo kurwanya umuriro. Ibi bikoresho bikora cyane bihuza imbaraga za fiberglass hamwe nibiranga bidasanzwe bya PTFE, bikavamo umwenda uruta mubihe bikabije. Ku bijyanye n’umutekano w’umuriro, imyenda isize PTFE igaragara kubera ubushobozi bwabo bwo guhangana nubushyuhe bwo hejuru, kurwanya ikwirakwizwa ry’umuriro, no gukomeza ubusugire bw’imiterere mu gihe cy’umuriro. Iyi ngingo iracengera mubice byo kurwanya umuriro byimyenda ya PTFE, igenzura imiterere yabyo, ibipimo ngenderwaho, hamwe nukuri kwisi kugirango iguhe gusobanukirwa neza nubushobozi bwabo bwo kurwanya umuriro.

Gusobanukirwa Ibigize nibyiza bya PTFE Bipfunyitse
Imiterere yimyenda ya PTFE
Imyenda ya PTFE igizwe nibikoresho fatizo, mubisanzwe fiberglass, bisizwe na polytetrafluoroethylene (PTFE). Uku guhuza kudasanzwe bivamo ibikoresho bizungura imbaraga za fiberglass hamwe nubusemburo bwimiti bwa PTFE. Fiberglass substrate itanga imbaraga zidasanzwe kandi zihamye, mugihe PTFE itanga ibintu bidafite inkoni, imiti irwanya imiti, hamwe nubushyuhe bukabije.
Igikorwa cyo gutwikira kirimo gukoresha ibice byinshi bya PTFE kuri fibre yububiko. Ubunini n'umubare w'ibyiciro birashobora gutegurwa kugirango byuzuze ibisabwa byihariye. Imyenda imwe irashobora kuba ifite PTFE iri hagati ya 15% kubisabwa byoroshye kugeza 85% kubicuruzwa bisize cyane. Ubu buryo bwinshi butuma ababikora bakora imiterere yimyenda ikoreshwa mubikorwa bitandukanye byinganda nubucuruzi.
Ubushyuhe bwa PTFE
PTFE, ibyingenzi byingenzi muribi bitambaro bya Teflon , bifite imiterere idasanzwe yubushyuhe. Ifite aho gushonga igera kuri 327 ° C (620 ° F) kandi irashobora kugumana imiterere yumubiri ku bushyuhe bugera kuri 260 ° C (500 ° F). Uku kurwanya ubushyuhe bwo hejuru ni ingenzi cyane mubikorwa bidashobora kurwanya umuriro, kuko bituma imyenda igumana ubusugire bwayo hamwe nimico irinda nubwo ihura nubushyuhe bukabije.
Byongeye kandi, PTFE ifite ubushyuhe buke bwumuriro, bivuze ko bidahita byimura ubushyuhe. Uyu mutungo ugira uruhare mubikorwa byawo nkinzitizi yubushyuhe, ifasha kugabanya umuvuduko woherejwe nubushyuhe mugihe cyumuriro. Ibikoresho kandi bifite ubushobozi bwihariye bwubushyuhe, bikabasha gukuramo ingufu zitari nke zumuriro mbere yuko ubushyuhe bwayo buzamuka cyane.
Imiti ihamye hamwe no gucana umuriro
Kimwe mu bintu by'ingenzi bigira uruhare mu kurwanya umuriro w'imyenda isize PTFE ni imiti ihamye ya PTFE. Imiyoboro ikomeye ya karubone-fluor muri PTFE ituma irwanya cyane imiti yimiti, harimo na okiside. Uku gushikama bivuze ko PTFE idashyigikira byoroshye gutwikwa, bigatuma irinda umuriro.
Iyo uhuye numuriro, PTFE ikunda char aho gutwika. Ubu buryo bwo kwishyiriraho butanga urwego rukingira rukomeza kubuza ikwirakwizwa ryumuriro kandi rugafasha gukomeza uburinganire bwimyenda. Umuriro muke wa PTFE, ufatanije nubushobozi bwawo bwo kuzimya, bituma uhitamo neza kubisabwa aho umutekano wumuriro wambere.
Ibipimo byo kurwanya umuriro no gupima imyenda ya PTFE
Ibipimo mpuzamahanga byo kurwanya umuriro
Imyenda ya PTFE isuzumwa cyane kugirango yizere ko yujuje ubuziranenge bukomeye bwo kurwanya umuriro. Ibipimo biratandukanye bitewe nibisabwa kugenewe hamwe na geografiya. Bimwe mubipimo mpuzamahanga bizwi cyane harimo:
- ASTM E84: Uburyo bwikizamini gisanzwe kubutaka bwo gutwika Ibiranga ibikoresho byubaka
- EN 13501-1: Gutondekanya umuriro mubicuruzwa byubwubatsi nibintu byubaka
- UL 94: Igipimo cyibizamini byo gutwika ibikoresho bya plastiki kubice mubikoresho nibikoresho
Ibipimo ngenderwaho bisuzuma ibintu bitandukanye byerekana imikorere yumuriro, harimo ikwirakwizwa ryumuriro, iterambere ryumwotsi, hamwe no kurwanya umuriro. Imyenda ya PTFE isanzwe ikora neza cyane muribi bizamini kubera imiterere yabyo irwanya umuriro.
Ibizamini byihariye byo kurwanya umuriro
Kugirango usuzume umuriro urwanya imyenda ya PTFE cyangwa igitambaro cya PTFE , abayikora na laboratoire yigenga bakora ibizamini bitandukanye. Ibi bishobora kubamo:
- Ikizamini cya Vertical Flame: Gupima ubushobozi bwimyenda yo kuzimya no kurwanya ikwirakwizwa ryumuriro
- Ikizamini cya Radiant Heat Resistance Test: Isuzuma imikorere yibikoresho iyo ihuye nubushyuhe bukabije
- Kugabanya igipimo cya Oxygene (LOI) Ikizamini: Kugena byibuze byibuze umwuka wa ogisijeni ukenewe kugirango ushigikire
Ibi bizamini bitanga amakuru yingirakamaro yukuntu imyenda ya PTFE itwikiriye yitwara munsi yumuriro utandukanye, ifasha injeniyeri nabashushanya guhitamo ibikoresho bibereye mubisabwa byihariye.
Ibipimo ngenderwaho hamwe nu amanota
Ukurikije ibisubizo by'ibizamini byo kurwanya umuriro, imyenda isize PTFE ihabwa amanota yo gukora. Iri gereranya risanzwe risuzuma ibintu nka:
- Ikirangantego cyo gukwirakwiza ibirimi: Gupima uburyo umuriro ugurumana vuba hejuru yibikoresho
- Igipimo cyatejwe imbere yumwotsi: Kugabanya ingano yumwotsi ukorwa mugihe cyo gutwikwa
- Gutwika-Kurwanya: Gusuzuma ubushobozi bwimyenda yo gukumira umuriro
Imyenda ya PTFE ikunze kugera ku ntera yo hejuru muri ibi byiciro, bigatuma ikoreshwa neza muri porogaramu aho umutekano w’umuriro ari ngombwa. Gusobanukirwa n'ibipimo ngenderwaho bifasha abadondora hamwe nabakoresha-nyuma guhitamo umwenda ukwiye wa PTFE kugirango bakenure umuriro.
Porogaramu ninyungu zumuriro-utarwanya PTFE Umwenda wuzuye
Inganda ninganda zikoreshwa
Ibikoresho birwanya umuriro byimyenda ya PTFE ituma biba ingirakamaro mubikorwa bitandukanye byinganda. Mubikorwa byo gukora, iyi myenda ikoreshwa kenshi:
- Imikandara ya convoyeur murwego rwo hejuru
- Inzitizi zo gukumira ibikoresho bikoresha ibikoresho byashongeshejwe
- Imyenda ikingira ahantu ho gusudira
Ubushobozi bwimyenda ya PTFE yo guhangana nubushyuhe bukabije mugihe ukomeje ubusugire bwimiterere itanga ibikorwa byumutekano kandi neza muribi bidukikije bisaba. Byongeye kandi, imitungo yabo itari inkoni irinda iyubakwa ryibikoresho, kugabanya ibisabwa byo kubungabunga no kuzamura umusaruro muri rusange.
Gukoresha Ubwubatsi nubwubatsi
Mu nganda zubaka, imyenda irwanya PTFE irwanya umuriro yabonye ibikoresho byinshi, harimo:
- Ubwubatsi bwa Tensile bwububiko bunini
- Ibisenge byo hejuru kubibuga bya siporo nibibuga byindege
- Imyenda irwanya umuriro n'ibice mu nyubako rusange
Gukomatanya kurwanya umuriro, kuramba, hamwe nuburemere bworoshye bituma PTFE itwikiriye imyenda ihitamo neza kububatsi naba injeniyeri. Ibi bikoresho birashobora gutanga ubwiza bwubwiza nibintu byingenzi birinda umutekano wumuriro, bigira uruhare mumutekano rusange nimikorere yinyubako zigezweho.
Urwego rwo mu kirere no gutwara abantu
Inganda zo mu kirere no gutwara abantu zishingiye cyane ku bikoresho birwanya umuriro kugira ngo umutekano w’abagenzi ubungabunge. Imyenda ya PTFE ikoreshwa mubikoresho bitandukanye, nka:
- Indege imbere
- Ibikoresho byo kubika icyogajuru
- Kwicara birinda umuriro no gufunga mu modoka zitwara abantu
Imiterere yoroheje yimyenda isize PTFE, ifatanije nuburyo bwiza bwo kurwanya umuriro, ituma biba byiza kuriyi porogaramu aho umutekano ndetse n’ibikorwa bya peteroli ari byo byingenzi. Ubushobozi bwabo bwo kubahiriza amategeko akomeye yumutekano wumuriro mugihe batanga imikorere irambye byatumye baba ikirangirire mubyogajuru bigezweho no gutwara abantu.
Umwanzuro
Imyenda isize PTFE yerekanye ko ari ibikoresho bidasanzwe mugihe cyo kurwanya umuriro. Ibigize bidasanzwe, bihuza imbaraga za fiberglass hamwe nubushyuhe bwa chimique na chimique ya PTFE, bivamo umwenda uruta mubihe bikabije. Kuva guhangana nubushyuhe bwo hejuru kugeza kurwanya ikwirakwizwa ryumuriro, ibyo bikoresho bitanga uburinzi butagereranywa ahantu hashobora kwibasirwa n’umuriro. Mu gihe inganda zikomeje gushyira imbere umutekano n’imikorere, icyifuzo cy’imyenda itwikiriwe n’umuriro PTFE gishobora kwiyongera, bigatuma udushya twinshi muri uru rwego.
Ibibazo
