Umuyoboro wa Teflon ni iki (PTFE)?

1. Kuki byitwa umuyoboro wa Teflon (PTFE)? Umuyoboro wa Teflon witwa ute?

Umuyoboro wa Teflon, uzwi kandi ku izina rya PTFE, bakunze kwita “umwami wa plastiki”, ni polymer ndende ya polymerisime hamwe na tetrafluoroethylene nka monomer. Ibishashara byera, bisobanutse, ubushyuhe buhebuje no kurwanya ubukonje, birashobora gukoreshwa igihe kirekire kuri -180 ~ 260ºC. Ibi bikoresho ntabwo birimo pigment cyangwa inyongeramusaruro, irwanya aside, irwanya alkali hamwe nudukoko twinshi kama, kandi ntishobora gukemuka mumashanyarazi yose. Muri icyo gihe, PTFE ifite ibiranga ubushyuhe bwo hejuru hamwe na coeffisiyeti yo hasi cyane, bityo irashobora gukoreshwa mu gusiga amavuta, bigatuma iba umuyoboro mwiza wo gutwikira byoroshye gusukura byoroshye imbere yimbere yimiyoboro y'amazi.

2. Ubwoko bwa pipelon

①. Teflon yoroshye ya bore itunganijwe ikozwe muri 100% ya PTFE itavuwe kandi ntabwo irimo pigment cyangwa inyongeramusaruro. Irakwiriye gukoreshwa mu ikoranabuhanga mu kirere no gutwara abantu, ibikoresho bya elegitoroniki, ibice na insulator, gukora imiti n’imiti, gutunganya ibiryo, ubumenyi bw’ibidukikije, icyitegererezo cy’ikirere, ibikoresho byohereza amazi hamwe na sisitemu yo gutunganya amazi. Imiyoboro yose iraboneka muri anti-static (carton) cyangwa verisiyo y'amabara.

②. Umuyoboro wa Teflon wakozwe mu bikoresho 100% bya PTFE bitavuwe kandi ntabwo birimo pigment cyangwa inyongeramusaruro. Ifite imiterere ihindagurika kandi irwanya torsional, itanga imikorere myiza mubisabwa bisaba radiyo igoramye, ubushobozi bukomeye bwo guhangana nigitutu cyangwa guhangana. Inzogera ziraboneka hamwe na flares, flanges, cuffs cyangwa guhuza ibisubizo byinshi byateguwe neza. Imiyoboro yose iraboneka muri anti-static (carbone).

③. Ibiranga ubushyuhe hamwe no kurwanya ruswa ya teflon capillary tubes yakoreshejwe cyane mu nganda zirwanya ruswa, nk'inganda z’imiti, gutoragura, amashanyarazi, ubuvuzi, anodize n’izindi nganda. Imiyoboro ya capillary ifite cyane cyane irwanya ruswa, irwanya igipimo cyiza, irwanya gusaza neza, imikorere myiza yo kohereza ubushyuhe, irwanya rito, ingano nto, uburemere bworoshye nuburyo bworoshye.
