PTFE vs Teflon: Ese ni bimwe? – Besteflon

Iyo dukorana n'abakiriya bo mu mahanga, dukunze guhura n'iki kibazo: ibishushanyo bigaragaza umuyoboro wa PTFE, mu gihe ibiciro by'abatanga ibicuruzwa biwushyira ku rutonde rw'umuyoboro wa Teflon, bigatuma amakipe ashinzwe gutanga amasoko atamenya neza niba bavuga ku bikoresho bimwe kandi bigatuma habaho kwemeza gutinda no gutinda. Ikibazo gikomeye kurushaho, bamwe mu batanga amasoko bakoresha "Teflon" mu kwerekana PFA cyangwa FEP—kubera ko ikirango cya Teflon® gikubiyemo ibikoresho byinshi. Iyi ngingo itanga ibisobanuro birambuye ku magambo, ikirango, n'ibipimo ngenderwaho mu gutanga amasoko ahantu hamwe.

•PTFE na Teflon ni ibikoresho bimwe;Teflon® ni izina ry'ubucuruzi rya PTFE gusa.

•Ariko, ijambo "Teflon" ryakoreshejwe cyane mu nganda nobishobora kuba PTFE, PFA, cyangwa FEP.

•Chemours (yahoze ari DuPont) ifite ikirango cya Teflon®;abatanga ibicuruzwa batabifitiye uburenganzira ntibashobora kubikoresha mu buryo bwemewe n'amategeko.

•Umwanzuro wo kugura ugomba kugaragaza PTFE aho kugaragaza Teflonkugira ngo hirindwe ko ibyo umuntu atanze bitaba byoroshye.

•"Teflon tube" ifite igiciro gito cyane birashoboka cyane ko idakorwa hakoreshejwe ibikoresho fatizo bya Chemours;ibi bigomba kwemezwa.

Ese PTFE na Teflon ni ibintu bimwe?

Iki ni cyo kibazo cy'ingenzi, kandi igisubizo ni cyoroshye: yego, PTFE na Teflon ni ibikoresho bimwe. Ariko, "ibikoresho bimwe" na "ijambo rimwe" ntibisobanura ikintu kimwe mu bijyanye n'amasoko—gusobanukirwa iri tandukaniro bituma ibibazo byose bikurikira byoroha.

PTFE = Polytetrafluoroethylene = Izina ry'ikinyabutabire

PTFE isobanura Polytetrafluoroethylene, izwi cyane mu Gishinwa nka "polytetrafluoroethylene." Iyi ni inyito y'ibinyabutabire yerekeza kuri polymer ikozwe muri tetrafluoroethylene monomers. Hatitawe ku isoko ry'ibikoresho fatizo, ibicuruzwa byose bya polytetrafluoroethylene bikorerwa n'ikigo icyo ari cyo cyose byitwa PTFE—ijambo risanzwe ritari iry'uruganda runaka.

Teflon® = Ikirango cyanditswe cya DuPont

Teflon® ni ikirango cyanditswe cya Chemours (cyakomotse kuri DuPont mu 2015). Mu 1938, umuhanga mu bya siyansi wa DuPont, Roy Plunkett, yavumbuye PTFE ku bw'impanuka, maze isosiyete itangira kuyicuruza ikoresheje ikirango cya Teflon® mu 1945. Mu by'ukuri, Teflon® yerekeza kuri "PTFE yakozwe na DuPont/Chemours" - nkuko Kleenex® yerekeza ku bwoko bwihariye bw'amatafari y'impapuro.

Ariko, ukuri ni ikintu kigoye kurusha uko ibisobanuro bibivuga. Mu nganda, "Teflon" yahindutse izina rya PTFE, kandi abatanga ibicuruzwa benshi bakoresha iri jambo mu gusobanura ibicuruzwa byabo nta burenganzira—ikintu gikunze kugaragara cyane mu nganda z’Ubushinwa: iyo abakiriya basabye "imiyoboro ya Teflon," abatanga ibicuruzwa bose bemera ko ibi bivuga imiyoboro ya PTFE. Muri Besteflon, dukunda guhura n’ibibazo nk’ibyo; nyuma yo kwemeza ibisabwa n’ibikoresho, duhora dusobanura PTFE mu nyandiko zemewe kugira ngo twirinde ko ibintu bitagaragara neza.

 

Kuki "Teflon" itavuga PTFE byanze bikunze?

Iyo Teflon iba ari izina ry’ubucuruzi rya PTFE gusa, ikibazo cyari kuba cyoroshye. Ariko, mu by’ukuri, Chemours icuruza fluoropolymer zirenze imwe munsi y’izina rya Teflon®. Iki kintu ni cyo ntandaro y’urujijo mu itangwa ry’amasoko kandi gishimangira ko ari ngombwa gukoresha neza inyandiko zigaragaza imiterere y’ibicuruzwa.

Chemours ubu igurisha ibikoresho bikurikira munsi y’ikirango cya Teflon®:

 

 

Ibi bivuze ko iyo umutanga serivisi avuze ati "dutanga imiyoboro ya Teflon," ashobora kuba yerekeza ku miyoboro ya PTFE, imiyoboro ya PFA, cyangwa imiyoboro ya FEP. Ibi bikoresho bitatu bitandukanye cyane mu bushyuhe bwabyo ntarengwa, ibisabwa mu gutunganya, n'ibiciro; ikosa ry'inyuguti imwe rishobora gutuma urwego rw'imikorere rutandukanye rwose iyo rutanzwe.

Inama: Buri gihe koresha amazina y'imiti (PTFE/PFA/FEP) mu nyandiko zo kugura, ibisobanuro, n'amasezerano; irinde gukoresha "Teflon." Ubu si ugushaka gusa ahubwo ni uburyo bworoshye bwo gukumira impaka zo gutanga. Menya ko Besteflon yoseIbikoresho bya PTFE mu miyoborozanditseho amazina y’ibinyabutabire aho kuba "Teflon" - kuko ubwiza buruta ubworoherane.

 

Ni nde nyiri ikirango cya Teflon®?

Nubwo gutunga ikirango cy'ubucuruzi bishobora gusa n'aho ari ikibazo cyemewe n'amategeko, bigena neza niba abagutanga bashobora gukoresha ijambo "Teflon" mu buryo bwemewe n'amategeko n'ibikoresho bikoreshwa mu "tube ya Teflon" uguze.

Amateka y'ikirango

•1938,Umuhanga mu bya siyansi wa DuPont, Roy Plunkett, yavumbuye PTFE.

•1945:DuPont yandika ikirango cya Teflon® inatangira kugicuruza.

•2015:DuPont yashyize ubucuruzi bwayo bw'imiti ikoreshwa mu gukora imiti mu isosiyete yigenga ya Chemours, aho ikirango cya Teflon® cyahawe Chemours.

•Skure, Chemours ifite ikirango cya Teflon® kandi itanga uburenganzira bwo gutanga uruhushya ku bagura resin ya PTFE ku isi yose.

Ibi bivuze iki ku bijyanye no gutanga amasoko?

Gutunga ikirango cy'ubucuruzi byemewe n'amategeko bifite ingaruka ebyiri zifatika ku itangwa ry'amasoko:

1. Umutanga serivisi wawe ashobora kuba adafite uburenganzira bwo gushyira ikimenyetso kuri Teflon® kuri icyo gicuruzwa.Iyo uruganda rukora imiyoboro rukoresheje ikirango cya Teflon® ku birango by'ibicuruzwa cyangwa imbuga za interineti rutabonye uburenganzira bw'ikirango buturutse kuri Chemours, ibi bifatwa nk'ikosa ry'ikirango ryemewe n'amategeko. Ibi ntibigira ingaruka ku bwiza bw'ibikoresho ubwabyo—inganda nyinshi zo mu Bushinwa zikoresha resin ya PTFE ikorerwa mu gihugu (urugero, Dongyue, Haohua, nibindi), yujuje ibisabwa by'imikorere—ariko ntushobora gushyira ikirango ku gicuruzwa cya nyuma na Teflon®.

2. "Umuyoboro wa Teflon" ntushobora gukoreshwa nk'ishingiro ryo kwemerwa.Itangazo ryo kugura rigomba kugaragaza "umuyoboro wa Teflon"; umucuruzi ashobora gutanga ubwoko ubwo aribwo bwose bw'umuyoboro wa fluoropolymer. Kugaragaza gusa "umuyoboro wa PTFE" cyangwa "umuyoboro wa PFA" bishobora kuba ibipimo ngenderwaho byo kwemerwa mu gihe habayeho impaka.

 

Ese imiterere ya PTFE ituruka ahantu hatandukanye isa neza?

Nyuma yo gusobanura ibibazo bijyanye n'ibirango by'ubucuruzi n'amategeko agenga amazina, impungenge zikurikira ku matsinda ashinzwe gutanga amasoko ni izi zikurikira: Ese ibikoresho bya PTFE bituruka ahantu hatandukanye bigaragaza imiterere imwe? Igisubizo ni "mu by'ukuri bisa, hamwe n'impinduka nto" — iri tandukaniro muri rusange ntirigira ingaruka ku mikorere mu bikorwa byinshi ariko rishobora guteza imbogamizi mu bihe by'ubuhanga buhanitse.

Ibice bimwe by'ibikoresho byose bya PTFE

Imiterere ya PTFE igizwe n'iminyururu igororotse igizwe n'imigozi ya karuboni na fluorine, kandi iguma ari imwe nubwo yaba ikomoka kuri Chemours, Daikin, Dongyue, cyangwa abandi batanga. Imiterere ikurikira irahuye ku bwoko bwose bwa PTFE:

• Kutagira ubushobozi bwo gukoresha imiti – hafi nta ngaruka za shimi zibaho.

• Ingano y'ubushyuhe bw'akazi: -65°C kugeza +260°C

• Igipimo cyo kugongana – 0.1, kiri hasi cyane ku bikoresho bikomeye

• Imiterere ya Dielectric – Dielectric constant: 2.1; Ingufu za Dielectric: 25 kV/mm

• Ntifatana – Ibintu hafi ya byose ntibifatana

Ni izihe tandukaniro zishobora kubaho

Kusa kw'imiterere y'imiti ntibivuze ko ibicuruzwa byose bya PTFE bingana. Ibintu bikurikira bishobora gutuma habaho itandukaniro hagati y'ibicuruzwa biva mu byiciro bitandukanye cyangwa ababicuruza:

 

 

Inama z'ingenzi ku bijyanye no gutanga amasoko:Ku bijyanye n'ikoreshwa rijyanye no gutunganya imiti isanzwe cyangwa ikoreshwa mu nganda rusange, itandukaniro ry'ibikoresho fatizo ni rito cyane. Ariko, niba umushinga ushyiraho ibisabwa bikomeye ku buryo bwo kwihanganira uburebure bw'umurambararo w'imbere (urugero, imiyoboro ya PTFE capillary), uburyo bworoshye bw'inkuta z'imbere, cyangwa uburyo bwo kwirinda umuvuduko w'amashanyarazi igihe kirekire, ntugomba kwibanda gusa ku kumenya niba ibikoresho ari PTFE, ahubwo no ku kugenzura ubushobozi bw'umutanga serivisi zo gusohora no kugenzura ubuziranenge. Uburyo bwo kugenzura ubuziranenge kuri BesteflonImiyoboro ya PTFE igenda neza——harimo ikizamini cyo gufunga umwuka, ikizamini cyo gufata umuvuduko wa hydrostatic, ndetse n'urukurikirane rw'igenzura nko gupima umuvuduko ukabije, ikizamini cyo guturika kwa hydraulic n'ikizamini cyo gucika intege, kwemeza ko ibicuruzwa byujuje ibisabwa mu nganda za fluoroplastic. Byagenewe by'umwihariko ibintu nk'ibi bifite ubuziranenge bwo hejuru.

Yagombye kwandikwa gute ku itegeko ryo kugura?

Ikiganiro cyagaragaje itandukaniro riri mu mategeko agenga amazina, ibirango by'ubucuruzi, n'ibikoresho, amaherezo cyibanze ku kibazo gifatika: ni gute aya makuru yasobanurwa mu nyandiko zigenewe kugura no mu bisobanuro bya tekiniki?

Koresha amazina y'ibinyabutabire, ntabwo ukoreshe amazina y'ibirango

 

Kwandika izina ry'ikintu gusa ntibihagije

Kuvuga gusa "PTFE tube" ntibihagije. Ibisobanuro byuzuye by'itangwa ry'amasoko bigomba kuba bikubiyemo ibi bikurikira:
