Kumurongo wihuta wapakira, kashe yubushyuhe ni icyuho. Igihe cyose plastiki yashongeshejwe ifashe ku cyuma gifunga, umurongo uhagarara kugirango usibe - byica umusaruro. Ikidodo kibi cyose cyohereza imifuka gusubira mubikorwa. Buri kashe yambarwa ipfa igura ibihumbi kugirango bisimburwe.
Igisubizo kiroroshye kubeshya: shyira mu bikorwa PTFE ubushyuhe bwo hejuru kaseti
Aokai PTFE yatanze kaseti ya PTFE kubakora ibikoresho byo gupakira hamwe nabakoresha-imyaka. Iyi ngingo ikubiyemo indangagaciro enye zikoreshwa - kurekura anti-inkoni, kurinda ibikoresho, ubuziranenge bwa kashe, hamwe no guterana amagambo - hiyongereyeho ibipimo ngenderwaho byatoranijwe (substrate, ubushyuhe, ibifatika, ibikoresho bya mashini) kugirango bigufashe guhitamo kaseti ibereye kumurongo wawe.
Ibintu bine byingenzi byo gusaba indangagaciro za PTFE mugushushanya ubushyuhe
1. Kurandura ibisigazwa bifata - Gukomeza umusaruro-mwinshi
Nibyiza bya kaseti ya PTFE. Gupakira firime zirimo PE, PP, PET, na aluminiyumu ikomatanya ikunda koroshya no kwizirika ku cyuma cyambaye ubusa hejuru yubushyuhe, bigatuma imifuka imeneka, gutanyagura firime, hamwe nigihe cyo gukora isuku.
Uburyo PTFE ifasha: Ingufu zidasanzwe zo hejuru (ingoma ya 18-20 / cm) irwanya plastiki zashongeshejwe hamwe nibishishwa bishushe. Filime isohora neza buri cyiciro.
Igisubizo: Kwanga kugabanuka kw'igipimo; imashini ihagarika igihe cyo gukora isuku igabanukaho 80-90%.
2. Kurinda Ubushyuhe-Gufunga Ibikoresho - Ongera ibikoresho Ubuzima
Icyuma gifunga cyangwa icyuma gishyushya ni icyuma cyuzuye. Igihe kirenze, guterana muri firime no gukata ibyuma birashira, kandi okiside / ruswa ikubita hejuru.
PTFE nk'urwego rukingira kurinda: Kaseti ikora nk'igiciro gito, gisimbuzwa imyenda. Gusimbuza kaseti bifata iminota kandi bigura amafaranga ugereranije no gusana cyangwa gusimbuza kashe yabugenewe ($ 500- $ 5,000 +).
Igisubizo: Ibikoresho bya serivisi ubuzima buraguka cyane; gupfa gusimbuza intera ndende.
3. Homogenize Gukwirakwiza Ubushyuhe - Kuzamura Ikidodo gihoraho
Premium fiberglass-yongerewe imbaraga ya PTFE kaseti ifite uburyo bwo kugereranya no gukwirakwiza ubushyuhe. Irasubizaho ubusumbane buto hagati yicyuma gifunga na firime yo gupakira kurwego rwa micro.
Uburyo ikora: Kaseti ikwirakwiza ubushyuhe n'umuvuduko biringaniye ahantu hafunzwe.
Igisubizo: Ikidodo cyiza, gihamye gifite imbaraga zimwe - nta kashe ituzuye (kumeneka) cyangwa gutwika cyane (pinholes).
4. Coefficient yo hepfo yo hasi - Gutanga firime nziza
PTFE ya ultra-low kinetic friction coefficient (μ≈0.05-0.10) ifite agaciro karenze kashe. Irakoreshwa cyane mugukora amakariso hamwe nintoki zuburyo bwa vertical verisiyo yuzuza kashe (VFFS).
Inyungu: Kugabanya kwiruka kwiruka kwa firime; irinda firime irambuye; Kugabanya ibyubaka byubaka (iyo anti-static ikoreshwa).
Igisubizo: Kugaburira firime ihamye, jama nkeya.
Aokai PTFE itanga fiberglass ishyigikiwe na kaseti ya PTFE kugirango ushireho ubushyuhe. Silicone yacu PSA ihujwe na 260 ° C ikomeza serivisi, yemejwe nigeragezwa ryamasaha 1.000 yubusaza nta ooze ifata. Urwego rwumukara anti-static (irwanya ubuso 10⁶-10⁹ Ω) irahari kumirongo yihuta ya firime.
Ubushyuhe bwo gufunga ibintu buratandukanye cyane mubushyuhe bwakazi, imbaraga zo kwikuramo, no kwihuta. Ibisobanuro bikurikira bigomba kugenzurwa mugihe cyo gutoranya.
