Niki uzi kuri PTFE?

PTFE ni iki?

Polytetrafluoroethylene (PTFE) ni ubwoko bwa polymer polymerized hamwe na tetrafluoroethylene nka monomer. Ifite ubushyuhe buhebuje no kurwanya ubukonje kandi irashobora gukoreshwa igihe kirekire kuri minus 180 ~ 260 º C. Ibi bikoresho bifite ibiranga kurwanya aside, kurwanya alkali no kurwanya imiti itandukanye, kandi ntibishobora gukemuka mumashanyarazi yose. Muri icyo gihe, polytetrafluoroethylene ifite ibiranga ubushyuhe bwo hejuru, kandi coefficente yayo yo guterana ni mike cyane, bityo irashobora gukoreshwa mu gusiga amavuta, kandi ikanaba igipfundikizo cyiza cyo gusukura byoroshye igice cyimbere cyimiyoboro y'amazi. PTFE bivuga kongeramo igifuniko cya PTFE imbere mubisanzwe bisanzwe bya EPDM reberi, byera cyane.

Uruhare rwa PTFE

PTFE irashobora kurinda neza ingingo ya reberi aside ikomeye, alkali ikomeye cyangwa amavuta yubushyuhe bwinshi hamwe nibindi byangirika byitangazamakuru.

Intego

• Ikoreshwa mu nganda zamashanyarazi kandi nkurwego rwokwirinda, ibintu birwanya ruswa kandi birwanya kwambara kumashanyarazi no mumirongo yikirere, indege, ibikoresho bya elegitoroniki, ibikoresho, mudasobwa nizindi nganda. Irashobora gukoreshwa mugukora firime, amabati, inkoni, ibyuma, gasketi, indangagaciro, imiyoboro yimiti, ibyuma bifata imiyoboro, ibikoresho byabitswe, nibindi.
• Ikoreshwa mubijyanye nibikoresho byamashanyarazi, inganda zimiti, indege, imashini nizindi nzego kugirango isimbuze ibirahuri bya quartz kugirango isesengurwe ryimiti ya ultra-yera kandi ibike acide zitandukanye, alkalis hamwe n’umusemburo kama mubijyanye ningufu za atome, ubuvuzi, semiconductor n'izindi nganda. Irashobora gukorwa mubice byamashanyarazi bikabije, insinga nini yumurongo wa kabili, ibikoresho bya chimique birwanya ruswa, imiyoboro ya peteroli irwanya ubushyuhe bwinshi, ingingo zubukorikori, nibindi. amavuta, n'ibindi.
• PTFE irwanya ubushyuhe bwinshi no kwangirika, ifite amashanyarazi meza cyane, irwanya gusaza, amazi make, hamwe nuburyo bwiza bwo kwisiga. Nifu yamavuta yo kwisiga ikwiranye nibitangazamakuru bitandukanye, kandi irashobora gutwikirwa vuba kugirango ikore firime yumye, ishobora gukoreshwa mugusimbuza grafite, molybdenum nandi mavuta adasanzwe. Nibikoresho byo kurekura bikwiranye na thermoplastique na polimosetting polymers, hamwe nubushobozi buhebuje bwo gutwara. Ikoreshwa cyane munganda za elastomer na rubber no mukurinda ruswa.
• Nukuzuza resin ya epoxy, irashobora kunoza kurwanya abrasion, kurwanya ubushyuhe hamwe no kwangirika kwangirika kwa epoxy.
• Ikoreshwa cyane nkuguhuza no kuzuza ifu.

Ibyiza bya PTFE

• Ubushyuhe bwo hejuru - ubushyuhe bwo gukora bugera kuri 250 ℃
• Ubushyuhe buke - ubukanishi bwiza; Nubwo ubushyuhe bwamanutse kuri - 196 ℃, kuramba kwa 5% birashobora gukomeza.
• Kurwanya ruswa - kumiti myinshi nu mashanyarazi, iba inert kandi irwanya aside ikomeye na alkalis, amazi nudukoko twinshi kama.
• Kurwanya ikirere - bifite ubuzima bwiza bwo gusaza bwa plastiki.
• Amavuta menshi ni coefficente yo hasi yo kugabanuka mubikoresho bikomeye.
• Kudashyira hamwe - ni byibuze ubushyuhe bwo hejuru mubikoresho bikomeye kandi ntibukurikiza ikintu icyo aricyo cyose.
• Ntabwo ari uburozi - Ifite inertia physiologique, kandi ntigira ingaruka mbi nyuma yo guterwa igihe kirekire nkimiyoboro yamaraso ningingo.
• Gukwirakwiza amashanyarazi - birashobora kwihanganira voltage ya 1500 V.
