Hauv kev tsim khoom lag luam thiab lub neej niaj hnub, peb feem ntau ntsib cov teeb meem nyuaj xws li kev nplaum, kub kub, thiab corrosion. Txawm li cas los xij, muaj ib qho khoom siv, zoo li tus neeg saib xyuas tsis pom nrog cov txuj ci tshwj xeeb, uas tuaj yeem ua tau raws li cov kev cov nyom no yooj yim: Teflon daim kab xev.
Teflon daim kab xev, siab- zoo iav ntaub xov xov nyob rau hauv ntau yam thicknesses, PTFE txheej, thiab ib zaug xwb -slicon siab siab- rhiab nplaum txheej.
Teflon daim kab xev cov yam ntxwv tseem ceeb
Tsis zoo -Adhesive thiab Anti-Stick Zoo
Lwm cov ntaub ntawv pom tias nws nyuaj rau lo rau saum npoo ntawm PTFE vim nws muaj qhov qis tshaj qhov nro ntawm cov khoom siv. Teflon daim kab xev yog ib qho kev xaiv zoo rau kev kho cov teeb meem sticking vim qhov no feature. Teflon daim kab xev tau ua tiav cov yas molten, kub yaj nplaum, thiab cov khoom xyaw ntawm cov khoom noj los ntawm kev sib khi rau cov khoom siv xws li cov cua sov sealers, ziab daim hlau, thiab cov tais ci. Qhov no ua rau kev tu thiab tu kom yooj yim dua thiab ua kom cov khoom siv ntau lawm.
Kev tiv thaiv zoo rau qhov kub thiab txias
Qhov nruab nrab ua haujlwm kub ntau rau Teflon daim kab xev yog nruab nrab ntawm -70℃thiab +280 degree, thiab nws tuaj yeem tiv taus qhov kub thiab txias li 300℃rau lub sijhawm luv luv. Qhov no feature ua rau nws indispensable nyob rau hauv:
High - qhov kub thiab txias: Piv txwv li, nyob rau hauv yoj soldering shields, reflow soldering carriers, thiab cua sov qws wraps rau daim ntaub ntawv uas muaj xws li soldering thiab cua sov ntawm electronics.
Tsawg- Ib puag ncig Kub: Txawm tias nyob rau hauv cov khoom siv tub yees, PTFE tuav nws yooj yim thiab tiv taus brittleness.
Cov tshuaj tiv thaiv zoo tshaj plaws: PTFE nthuav tawm tshwj xeeb kev ruaj ntseg nyob rau hauv lub ntsej muag ntawm yuav luag txhua yam corrosive media thiab tshuaj kuab tshuaj, suav nrog cov acids muaj zog, cov hauv paus, thiab cov kuab tshuaj organic. Teflon daim kab xev yog li no cov khoom siv tiv thaiv kev ntseeg siab rau kev siv nrog rau cov yeeb nkab sealing, cov khoom siv tshuaj lom neeg, thiab kev tiv thaiv cov ntsiav tshuaj.
Superior Hluav taws xob rwb thaiv tsev: PTFE yog ib qho zoo tshaj uas tsis yog -polar khoom nrog ib tug tsawg dissipation yam thiab dielectric tas li. Raws li qhov tshwm sim, txawm tias nyob rau hauv siab - kub thiab siab - zaus, Teflon daim kab xev khaws nws cov khoom zoo insulating. Hauv kev siv hluav taws xob thiab hluav taws xob xws li cable wrapping, transformers, thiab motors, nws feem ntau siv los ua ib qho kev cuam tshuam kev cuam tshuam.
Kev Siv Tus Thawj Coj rau Teflon Daim Kab Xev: Teflon daim kab xev siv cov yam ntxwv tseem ceeb rau nws kom zoo dua hauv cov haujlwm hauv qab no:
Khoom noj khoom haus thiab ntim khoom: ci daim ntawv mats rau pastries thiab pastry khoom, tshav kub sealer hniav npog, thiab anti- stick conveyor siv.
Electronics thiab Hluav taws xob: Reflow / wave soldering carrier tiv thaiv, coil rwb thaiv tsev, cua sov caij wrapping, thiab Circuit Court board solder masking. Plastics thiab Roj Hmab Kev Lag Luam: Kub yaj cov nplaum nplaum, cov khoom siv laminating, thiab tiv thaiv - nplaum txheej rau cov ntawv qhia chais.
Kev lag luam tshuaj: Reactor thiab yeeb nkab flange sealing thiab tiv thaiv -corrosion linings.
Automotive Kev Lag Luam: Kev tiv thaiv rau siab - kub sensors thiab hlua hlua.
DIY Tsev Siv: Unclogging thiab sealing kav, ntxuav qhov cub, thiab tiv thaiv hlau soleplates.
Yuav Ua Li Cas Teflon Daim Kab Xev Yuav Xaiv thiab Siv?
Cov lus zais rau optimizing Teflon daim kab xev kev ua tau zoo yog xaiv hom tsim nyog:
Xav txog lub substrate:
Cov substrate nrov tshaj plaws yog fiberglass, uas yog qhov zoo tagnrho rau feem ntau ntawm cov ntawv thov kev lag luam vim nws qhov tshwj xeeb txhua yam muaj zog thiab ua haujlwm rau qhov kub thiab txias.
Polyimide substrate: Feem ntau siv nyob rau hauv ntau txoj kev siv hluav taws xob, nws muab kev ruaj ntseg zoo dua thiab kev txiav tsis kam.
Xav txog cov nplaum:
Cov nplaum uas siv ntau tshaj plaws rau Teflon daim kab xev yog silicone siab -sensitive nplaum, uas muab tshwj xeeb tsis kam rau kub kub.
Lub zog pib tack yog muab los ntawm acrylic kua nplaum, txawm li cas los xij ntawm qhov kub thiab txias, nws yuav tsis ua hauj lwm zoo li silicone nplaum.
Xaiv raws li thickness:
Cov thicknesses tsis tu ncua, xws li 0.08 txog 0.20 hli, ua haujlwm zoo rau feem ntau ntawm cov rwb thaiv tsev thiab tiv thaiv - daim ntaub ntawv lo. Cov ntawv thov xav tau kev tiv thaiv kev tiv thaiv ntau dua lossis kev puas tsuaj yuav tsum xaiv cov tuab tuab.
Cov lus qhia siv tseem ceeb:
Nto huv huv: Xyuas kom meej tias qhov chaw uas yuav tsum tau ua kom huv si, qhuav, thiab roj- dawb.
Kev Ruaj Ntseg Zoo: Txhawm rau lav kev sib cuag ntawm daim kab xev thiab qhov chaw, thov lub siab sib npaug thoob plaws hauv daim ntawv thov.
Nco ntsoov "Post-Curing": Cov nplaum nplaum lub zog yuav nce nrog lub sijhawm thiab qhov kub thiab txias tom qab siv rau qhov kub siab thaum pib. Cov txheej txheem no hu ua "post-kho."
