Uburinganire bwimyenda ya PTFE yubushyuhe bwo hejuru bugenwa nibintu bine: guhuza ibice (ingano ya 0.15-0.35 μ mm, viscosity, ibintu bikomeye), gutwikira & gucumura (gutwikira icyuma gikundwa kuburinganire), ubuziranenge bwibisobanuro (kuboha, kubanza kubivura), hamwe nibidukikije (20-25 ° C, <60% RH). Dip + blade ikomatanyirijwe hamwe iringaniza kwinjira no kugaragara neza.

Gusukura neza no kubungabunga byongera ubuzima bwimyenda yubushyuhe bwo hejuru. Isuku nyuma yo kuyikoresha na nyuma yo gukonja. Koresha umuyonga woroshye, ibikoresho bidafite aho bibogamiye, cyangwa inzoga kubirindiro. Ntuzigere ukoresha acide ikomeye / alkalis, byakuya, cyangwa ibyuma bisakara. Amavuta ya silicone asanzwe amavuta agabanya kwambara. Kurikiza aya mabwiriza kugirango wirinde kwangirika.

Imyenda ya PTFE yubushyuhe bwo hejuru hamwe nigitambara cya silicone byombi bikoresha umwenda wa fiberglass nkibanze ariko bitandukanye mubikoresho byo gutwikira (PTFE resin vs silicone rubber). PTFE irusha abandi kutagira inkoni, kwambara, no kurwanya imiti igera kuri 260 ° C. Umwenda wa Silicone utanga ibintu byoroshye guhinduka, kubika amashanyarazi, no kurwanya umuriro (kugeza kuri 230 ° C). Hitamo ukurikije ibyo ushyira imbere.

Imyenda ya PTFE yubushyuhe bwo hejuru (PTFE membrane material) ni ihitamo ryiza kubwubatsi bubi. Ibyiza byingenzi: ubuzima bwimyaka 30+ yo hanze, kwiyuhagira hejuru (amazi yimvura yoza umwanda), kohereza urumuri rworoshye (6-13%), Urwego rwumuriro A, nimbaraga zimeze nkicyuma munsi ya 1.5 kg / m². Ikoreshwa muri stade, ibibuga byindege, ninyubako zishushanyije kwisi yose.

Imyenda ya PTFE itanga ubushyuhe budasanzwe itanga imiti idasanzwe, irwanya aside ikomeye, alkalis, ibishishwa kama, hamwe na gaze yangirika. Iyi ngingo irambuye ibintu birwanya imbaraga zayo, imbogamizi (ibyuma bya alkali byashongeshejwe, imiti ikomeye ya fluorine), nibintu byingenzi nkubushyuhe, kwibanda, hamwe no guhangayika.

Kwinjiza PTFE ntabwo bigarukira gusa kumyenda ya fiberglass. Iyi ngingo itangiza ubundi buryo 7 - aramide, fibre karubone, PBI, ibyuma byoroshye, grafite, asibesitosi (byaciwe), hamwe na ceramic yuzuza - hamwe nibikorwa byabo, ibyiza, imipaka, hamwe nibikorwa byingenzi.

Imyenda ihumeka cyane PTFE yubushyuhe bwo hejuru ikomatanya ibintu bidafite inkoni, ituze ryumuriro, hamwe nikirere. Iyi ngingo irasobanura ibyingenzi byingenzi mukumisha imyenda, gutunganya ibiryo, gukora inganda, ibikoresho bya elegitoroniki, gutanga pneumatike, kurengera ibidukikije, nibikoresho byubaka.

Iyi ngingo isobanura impamvu umwenda wa fiberglass udafite alkali ari substrate yemewe kumyenda yubushyuhe bwo hejuru bwa PTFE. Ikubiyemo imiti ihuza imiti ikoresheje ibikoresho bya silane hamwe nibintu byingenzi bifatika nkubushyuhe bwumuriro, guhagarara neza, hamwe no kurwanya ruswa - kwemeza imikorere irambye mubidukikije.

Nigute ushobora guhitamo imyenda iboneye ya PTFE kubikorwa byubwubatsi? Mugihe uhisemo umwenda mwiza wa PTFE ushyizwe mubikorwa byo kubaka, ugomba gutekereza kubikenewe byumushinga, uko bikora, nuburyo bizagira ingaruka ku isi. Igice cya polytetrafluoroethylene nicyiza mukurinda ibintu umutekano,

Amabwiriza yo Guhitamo Iburyo bukwiye bwa PTFE Fiberglass Imyenda yo Kuringaniza Ubushyuhe bwo hejuru Kugira ngo uhitemo umwenda mwiza wa PTFE ushyizwemo fibre yububiko kugirango uhagarike akazi kubushyuhe bwinshi, ugomba kumenya imikorere yingenzi yibikorwa, ubucuruzi bwawe bukeneye, hamwe nubutunzi bwabatanga isoko. Imvange idasanzwe
