Umuyoboro wa PTFE w'icyuma kidasanza ni iki?

Imiyoboro ya PTFE yabanje gukoreshwa muri sisitemu ya hydraulic cyangwa pneumatic cyangwa mu rwego rw'indege maze ihita ikunzwe cyane. Imiyoboro n'imiyoboro byakozwe muri polytetrafluoroethylene bikora neza mu bihe bigoye by'ibidukikije n'inganda, bityo ikoreshwa ryabyo mu bucuruzi riri kwiyongera. Bitewe n'uko biboneka cyane mu bucuruzi kandi imikorere yabyo myiza, ibicuruzwa bya PTFE ni ibicuruzwa by'ingenzi ku masoko y'inganda, ubuvuzi n'abaguzi, aho bidakoreshwa gusa mu buryo gakondo, ahubwo binakoreshwa mu buryo budasanzwe kandi budasanzwe.

Umuyoboro wa PTFE urimo urukuta ni iki?

ItsindaUmuyoboro wa PTFEni umuyoboro ugizwe n'imbere ya PTFE hamwe n'inyuma y'igipfundikizo. Umuyoboro wa PTFE usa n'umuyoboro wa PTFE ufite igipfundikizo cyo hanze, byongera imbaraga zawo zo kurwanya umuvuduko. Guhuza igipfundikizo cyo hanze n'imbere ya PTFE bituma umuyoboro uba igikoresho cy'ingenzi mu bikorwa byinshi

Ibiranga umuyoboro wa PTFE

Umuyoboro wa PTFE ufite ibi bikurikira:

Ubudahangarwa bw'ubushyuhe n'ubukonje

kubungabunga

Nta burozi, isuku nyinshi

Ubushobozi buke cyane bwo kwinjira

Irwanya umunaniro

Uburemere bworoheje

Byoroshye gukoresha mu gusukura no kwica udukoko

Irwanya UV na ozone

Nta kintu na kimwe gikoreshwa mu kuvura ibiyobyabwenge

Ubudahangarwa bw'amazi

Ubudahangarwa bw'ingaruka

irwanya static

gukurura imiyoboro ya PTFE

Ibi bikurikira bigomba kwitabwaho mu gihe cyo kubihitamo kugira ngo bikoreshwe mu buryo bwihariye.

Ubwoko bw'umuyoboro ugororotse cyangwa ubwoko bw'umuyoboro ugoranye: Ibintu by'ingenzi bitandukanya imiyoboro ya PTFE ni umuyoboro ugoranye n'ingano. Umwobo w'umwobo ugororotse ni munsi cyangwa ungana na santimetero imwe. Muri icyo gihe, umuyoboro ugoranye uzaba muto cyane wa santimetero 12, naho umwobo ugoranye uzaba muto cyane wa santimetero 3.

Idatwara umuriro cyangwa itwara umuriro: Itanga umuriro uhoraho ni itanga umuriro uturuka ku kintu runaka iyo itanga umuriro unyuze mu muyoboro wa PTFE ku muvuduko mwinshi. Iyo wirengagije izi tanga umuriro uhoraho, bishobora guteza akaga nko guturika. Kubwibyo, imiyoboro ya PTFE rimwe na rimwe ikorwa mu bikoresho byihariye birwanya umuriro uhoraho kugira ngo hirindwe ubwinshi bw'amashanyarazi ahoraho.

Ubunini bw'urukuta rw'umuyoboro wa PTFE: ubunini bw'urukuta rw'umuyoboro wa PTFE buratandukanye. Mu mikoreshereze aho imiyoboro igoramye cyane, inkuta nini ni zo zifatwa mbere kuko zifite ubushobozi bwo guhangana neza. Inkuta nini z'umuyoboro nazo zitanga ubushobozi buke bwo kwinjira muri gaze, ariko zifata umwanya munini.

Ibikoresho byo kuboha: Ubusanzwe kuboha icyuma kidashonga ni byo bikunze gukundwa cyane mu bihe byinshi. Ariko, ku bijyanye no gukoresha mu mazi, koresha ubwoko bwa 316 bwo kuboha icyuma kidashonga. Byongeye kandi, niba umuyoboro ugomba gukoreshwa ahantu hangiza cyane, umuyoboro ukoreshwa ugomba kuba ukozwe mu cyuma kidashonga. Byongeye kandi, umuyoboro ugomba kuba ukozwe mu muringa, mu gihe umuyoboro uzakoreshwa ahantu hakomeye bitewe n'ubushobozi bwawo bwo gusiga amavuta.

Gukoresha umuyoboro wa PTFE

Uruganda rutunganya peteroli na gaze

Uruganda rw'ibyuma

uruganda rutanga amashanyarazi

Uruganda rukora impapuro

Inganda z'imiti

Inganda zikora ifumbire mvaruganda

Inganda z'ibinyabutabire

Boiler y'inganda

Ingufu zikonjesha n'ubukonje

Ikigo cy'ingufu za kirimbuzi

inganda z'imodoka

Ibyambu n'aho amato akorera

Mu guhitamo umuyoboro wa PTFE ukwiye, inganda zishobora kubyaza umusaruro ubwiza bwa PTFE kandi zikabona inyungu nyinshi zituruka kuri yo. Guhitamo ibikoresho bikwiye bizatuma habaho imikorere myiza kandi amaherezo bikagabanya ikiguzi cyo gutunga, aho ibicuruzwa byakoreshejwe hose.

Umuyoboro wa PTFE ukozwe mu cyuma kidafunze (umuyoboro w'amashanyarazi)

Umuyoboro wa PTFE uboshye mu cyuma kidafunze(conductive core) PTFE irwanya imiti hafi ya yose, aside, alcool, coolants, elastomers, hydrocarbons, solvents, synthetics compounds hamwe n'amavuta ya hydraulic. Irwanya ubushyuhe bwinshi, ishobora guhangana n'ibintu byose kuva ku bushyuhe buke kugeza ku mwuka wose mu muyoboro umwe. Ubushyuhe ni -65° ~ 450°. Kubera imiterere ya PTFE irwanya gufatana, umuvuduko mwinshi w'amazi n'ubushyuhe buke, ntuzabona igitutu gito giterwa n'ibice biri ku muyoboro. Byoroshye kuyisukura, bituma umuyoboro umwe ukoreshwa mu bikorwa byinshi. Yoroshye kandi yoroheje, yoroshye kuyitwara, kuyifata no kuyishyiraho kurusha imiyoboro ya rubber, kandi ifite igipimo kimwe cy'umuvuduko. Ishobora kwihanganira kunama no guhindagura bidatinze bitewe n'umunaniro wo kunama. Irinda ubushuhe, ntifite hygroscopic, ni nziza ku mirizo y'ingurube mu micungire ya gaze nyinshi na sisitemu z'umwuka, urugero ruto rw'umusemburo ni ingenzi. Yoroshye gufata ibintu bidafatana nka kole, asphalt, amarangi, amavuta, kole, latex, lacquer na irangi. Ubushyuhe bwa chimique ntibuzabora cyangwa ngo bushire mu gihe cyo kuyikoresha. Nta gusaza, bitagizweho ingaruka n'ikirere, bishobora kubikwa igihe kirekire bitasaza. Ntibisaza mu gihe cyo kubikoresha. Birwanya gutungurwa, ntibiterwa no kunama guhoraho, guhindagura cyangwa igitutu cy'ingaruka, kandi bishobora kwihanganira ubukonje n'ubushyuhe bigenda bisimburana.

Polytetrafluoroethylene ni fluoropolymer yakozwe mu buryo bwa ikoranabuhanga. Kimwe mu bintu by'ingenzi ikora ni ubudahangarwa bwayo ku bintu bihumanya ikirere; ubushyuhe bwinshi buri hagati ya -100F na 500F (-73C na 260C) butuma ibi bikoreshwa. Ibikoresho by'umuyoboro bikwiranye n'ibintu byinshi biva mu mazi n'ubushyuhe bw'ikirere mu nganda; igipimo cyo hasi cyane cyo gukururana (0.05 kugeza 0.20) gishobora gutanga ubuso budafata; uburyo PTFE ifata amazi ni nto cyane, kandi ikizamini cya ASTM kiri munsi ya 0.01%. Byongeye kandi, byemejwe na FDA kugira ngo bikoreshwe mu biribwa no mu miti. Umuyoboro w'imbere wa PTFE "PTFE" woroshye ushyirwa hejuru kugira ngo ukomeze kuba mwiza cyane. Ukozwe muri resin ya polytetrafluoroethylene nziza, insinga 304 zikozwe mu cyuma kitagira umuhengeri, ingano runaka y'umukara wa karuboni wongerwa ku gice cy'imbere cya polytetrafluoroethylene (PTFE) kugira ngo utangire inzira ihoraho yo kuyobora ibikoresho by'icyuma, no kurekura umwuka cyangwa amazi menshi. Amashanyarazi adahindagurika. Gukoresha mu buryo buhoraho: -65°~450°(-54°~ 232°) Gukoresha mu buryo bw'igihe gito: -100°~ 500°(-73°~ 260°) Byujuje cyangwa birengeje ibisabwa na SAE 100R14. PTFE yujuje ibisabwa na FDA 21 CCFR 177.1550
