HaoFa PTFE feri ya feri yamashanyarazi idafite ibyuma bisize amabara PU cyangwa PVC bitwikiriye umurongo wa feri ya AN3

NikiTeflon?

Teflon hoseis byakozwe na umuyoboro udasanzwe twitaedIbikoresho bya PTFE, bigomba kunyuramokanda sinter, desiccation, ubushyuhe bwo hejuru bwo gucumura nibindi bikorwa, hanyuma unyuze muburyo runaka bwo kurangiza imiterere. Teflon, ubusanzwe izwi ku izina rya "non-stick coating" cyangwa "byoroshye koza ibikoresho bya wok"; Nibikoresho bya sintetike ya polymer ikoresha fluor kugirango isimbuze atome zose za hydrogen muri polyethylene.Nylon ni umuhanga cyane muri Amerika Carothers (Carothers) kandi ubuyobozi bwe bwitsinda ryubushakashatsi bwateye imbere, ni fibre ya mbere yubukorikori.

Itandukaniro hagati ya PTFE na nylon

1. Ubusanzwe Teflon ifite ubucucike burenze 2, mugihe nylon ifite ubucucike bwa 1.2. Ubucucike bwa Ptfe burasa nubucucike, ubushyuhe bwo hejuru nubukomezi bizaba byiza, kandi umuyoboro wa nylon uroroshye, urwanya ubushyuhe bwinshi kuruta umuyoboro wa PTFE urakennye, ariko kubera ko woroshye cyane, kuburyo ushobora guhuza nubutaka bwinshi.

2. Teflon imikorere ni super ubushyuhe bwo hejuru, kurwanya ruswa cyane, kwihanganira super kwambara, coefficient ultra-low friction. Nylon mukurwanya ubushyuhe bwinshi, kurwanya ruswa ni rusange, kwihanganira kwambara ni biciriritse, coefficient de fraux.

Kuki umuhuza afite imyelayo?

1. Ifite uburyo bwiza bwo kumeneka.

Ibyiza bya PTFE:

1. Kurwanya ubushyuhe bwinshi. Ubushyuhe bwabwo bukoreshwa bushobora kugera kuri 250 ℃, ubushyuhe rusange bwa plastike bugera kuri 100 ℃, plastike izashonga .Ariko teflon irashobora kugera kuri 250 ℃ nakomeza ukomeze imiterere rusange idahindutse, kandi nubushyuhe bwihuse burashobora kugera kuri 300 ℃, ntihazabaho impinduka mumitekerereze yumubiri.

2Kurwanya ubushyuhe buke, ku bushyuhe buke kugeza kuri -190 ℃, burashobora gukomeza kuramba 5%.

3. Kurwanya ruswa. Kubintu byinshi byimiti nigishishwa, byerekana inert, irwanya aside ikomeye nishingiro, amazi hamwe nudukoko twinshi kama.

4. Kurwanya ikirere. Teflon ntabwo ikurura ubuhehere, ntabwo yaka, kandi ihagaze neza cyane kuri ogisijeni, urumuri ultraviolet, bityo ikaba ifite ubuzima bwiza bwo gusaza muri plastiki.

5.Gusiga amavuta menshi. Teflon iroroshye cyane kuburyo na barafu idashobora guhangana nayo, ifite rero coefficient yo hasi yo guterana mubikoresho bikomeye.

6. Kudashyira hamwe. Kuberako umwuka wa ogisijeni - imbaraga za karubone intermolecular imbaraga ziri hasi cyane, ntakintu na kimwe gikurikiza.

7. Nta burozi. Ubusanzwe rero ikoreshwa mubuvuzi, nkimiyoboro yamaraso yubukorikori, byipi yumutima, byinoplasti nibindi bikorwa, nkingingo yatewe mumubiri igihe kirekire nta ngaruka mbi.

8. Amashanyarazi. Irashobora kwihanganira volt zigera ku 1500.
