Igipfundikizo cya PTFE kitaringaniye kiganisha kumurongo, pinholes, umuhondo, cyangwa imikorere idahuye. Kubisabwa nkimikandara yo gufunga ubushyuhe, imikandara ya convoyeur, hamwe no kurekura imirongo, uburinganire bwuburinganire bugira ingaruka nziza kubicuruzwa no mubuzima bwa serivisi.
Niki gitera umwenda utaringaniye? Igisubizo gikubiyemo ibice bine: gutunganya ibifuniko, gutwikira & gucumura, ubuziranenge bwibidukikije, hamwe n’ibidukikije.
Aokai PTFE yahinduye ibi bintu mubihumbi n'ibicuruzwa. Iyi ngingo isobanura buri kintu nuburyo bwo kubigenzura kubwiza-bwiza, bumwe Imyenda isize PTFE

Uzuza ibirimo (urugero, ifu ya ceramic)
Bihoraho, bitatanye neza
Hindura imiterere ya microscopique; uwuzuza adahuye atera ubunini butandukanye
Inama ifatika: Buri gihe ugerageze buri cyiciro cya emulioni ya PTFE kugirango igabanye ingano yubunini hamwe nubwiza mbere yumusaruro. Impinduka ya 10% mubucucike irashobora guhindura ipikipiki ya 5-8%.
Isano iri hagati yubunini bwa PTFE nuburinganire bwa buke akenshi ntibisuzugurwa. Emulisiyo hamwe na D50 munsi ya 0,12 mkm itemba byoroshye, bigatera isaro kumpande (gutwikiriye cyane kumpande) mugihe cyumye. Emulisiyo hamwe na D50 hejuru ya 0.4 μm yinjira muri fiberglass nabi, bikavamo ububobere bwo hejuru hamwe na fibre idakomeye. Urutonde rwiza (0.18-0.22 μ m) rutanga uburyo bwiza bwo kwinjira no gukora firime neza. Ikindi kintu gikomeye ni ibintu bitagaragara - birenze urugero bitera ifuro mugihe cyo gutwika, bigatera umwuka mubi uturika ugasiga ibizenga. Hafi ya surfactant nkeya itera uduce duto duto hamwe n '' amaso y amafi 'muburyo bwa nyuma. Kuburinganire bumwe, korana numuntu umwe utanga emulsiyo hanyuma usabe ibyemezo byicyiciro byerekana D50, D90, nijanisha rya surfactant.
Aokai PTFE ikoresha emulioni ya PTFE gusa hamwe no kugabana ingano yubunini bugabanijwe (D50 0.18-0.22 μ m, D90 <0.35 μ m). Ibi byemeza ko byinjira kandi bigahinduka neza kuri buri cyiciro cyimyenda.

2. Kuma no gucumura
Parameter
Ingaruka ku Bumwe
Igipimo cyumye
Kuma bitaringaniye (byihuse cyane cyangwa bitinda cyane) bitera ubunini bwa firime idahuye, guturika, cyangwa kugabanuka
Ubushyuhe
PTFE igomba gushonga muri firime ikomeza kuri 360-420 ° C. Ubushyuhe butaringaniye butera gushonga no kuringaniza
Igihe cyo gucumura
Igihe kidahagije formation gushiraho firime ituzuye; umwanya urenze → umuhondo cyangwa guta ubushyuhe
Ubushyuhe buringaniye ku ziko
Ahantu hashyushye / hakonje bitera gutandukana amabara (urugero, umuhondo mubice bimwe)
Dip + blade ihuriweho hamwe ninganda zinganda zo murwego rwohejuru PTFE imyenda yo hejuru. Dore impamvu: gutwikira byonyine bitanga 'ingaruka ya menisque' - igipfundikizo kiba kinini cyane ku nkombe kandi cyoroshye hagati hagati kubera uburemere bw’imisemburo ya emulioni nkuko umwenda usohoka mu bwogero. Ihinduka-hagati-hagati irashobora kuba 15-20% yubunini bwuzuye. Ipitingi yonyine, mugihe itanga ubuso buringaniye, irwana no kwinjira - PTFE iguma hejuru itarinze gukwirakwiza fibre ya fibre, biganisha ku kurwanya nabi abrasion. Inzira ihuriweho: kwibiza kugirango winjire, hanyuma uhite unyura munsi yicyuma cya muganga kugirango ukureho ibirenze kandi uringanize hejuru. Kubisubizo byiza, icyuho cyicyuma kigomba gushyirwaho 120-150% yubushyuhe bwa nyuma bwifuzwa, bikagabanuka mugihe cyumye. Ubushyuhe bugaragara hejuru y'itanura ryacumuye nabyo birakomeye - igipimo cya 10 ° C hejuru y'ubugari gishobora gutera imirongo igaragara.

Muncamake , gutwikira uburinganire bwimyenda yo hejuru ya PTFE biterwa nibintu bine bifitanye isano. Ipitingi (ingano yubunini, viscosity, ibirimo bikomeye) niyo ntandaro. Igikorwa cyo gutwikira no gucumura - cyane cyane gukoresha dip + icyuma hamwe - nicyiciro gikomeye. Substrate nziza kandi mbere yo kuvura itanga umusingi. Ibidukikije bitanga umusaruro byemeza ko bihoraho.
Kubisaba gusaba bisaba uburinganire buhanitse (urugero, kaseti zifunga ubushyuhe, kurekura imirongo yibicuruzwa bifatika), dip + blade ikomatanyirijwe hamwe ninganda zahabu. Kurikirana buri kintu buri gihe, komeza ibidukikije bidahungabana, kandi ugerageze emulisiyo yinjira kugirango igabanye ingano.
