Nsalu yotentha kwambiri ya PTFE PTFE-yokutidwa ndi fiberglass ) imadziwika ndi kukana kutentha, kusakhala ndi ndodo, komanso kusagwira ntchito kwamankhwala. Koma kwenikweni imakhala nthawi yayitali bwanji? Yankho lake si lophweka - limasiyanasiyana kuyambira miyezi ingapo mpaka zaka zingapo, malingana ndi momwe ntchito ikugwirira ntchito komanso momwe zimakhalira bwino.
Aokai PTFE yapereka nsalu za PTFE pazogwiritsa ntchito zambiri. Pansipa tikufotokozera zinthu zomwe zimakhudza moyo pazochitika zilizonse, kenako perekani zoyembekeza zenizeni za moyo pazinthu zisanu ndi chimodzi zomwe zimagwiritsidwa ntchito nthawi zambiri - kuyambira kuphika chakudya kupita ku anti-corrosion.
Zambiri Zomwe Zimakhudza Moyo Wautumiki - Gwiritsani Ntchito Zonse
Musanayambe kuyang'ana ntchito zenizeni, mvetsetsani zinthu zonse zomwe zimafupikitsa kapena kuwonjezera moyo wa nsalu za PTFE.
1. Kuwongolera kutentha ndikofunikira
Kutentha kogwira ntchito kwa nthawi yayitali ndi -70 ° C mpaka 260 ° C. Maulendo ang'onoang'ono mpaka 350 ° C ndizotheka, koma kutentha kwanthawi yayitali kumawononga kapangidwe kazinthu ndikufupikitsa moyo.
Zoyeserera: Zinthuzo zimasunga magwiridwe antchito pambuyo powonekera mosalekeza pa 250 ° C kwa masiku 200.
Lamulo la chala chachikulu: Pa 10 ° C iliyonse pamwamba pa 260 ° C, chiwopsezo cha kuwonongeka chimawonjezeka kawiri. Khalani osapitirira malire.
2. Pewani kuwonongeka kwa thupi - mikwingwirima yakuthwa ndi mdani
Pewani mikwingwirima yakuthwa pakukhazikitsa ndikugwiritsa ntchito. Mikwingwirima imapanga malo opanikizika ndipo imatha kuyambitsa kung'ambika - makamaka ikagwiritsidwa ntchito ngati malamba otumizira. Mzere wa crease ukapangika, gawo lapansi la fiberglass limasweka pansi, ndipo zokutira zimang'ambika.
3. Kuwonekera kwa mankhwala ndi kuipitsidwa
PTFE imakana ma acid amphamvu ndi alkalis bwino kwambiri. Komabe, kukhudzana kwa nthawi yayitali ndi madontho amafuta, zomatira zotentha zosungunuka, kapena ma inki pa kutentha kwakukulu kungapangitse kuti kukalamba kufulumizitse. Ngakhale PTFE ndi inert, zotsalira zinthu akhoza carbonize pamwamba ndi kuwononga kumasulidwa katundu.
4. Kukana kuvala kwa makina
Kukangana kosalekeza ndi kukangana kumawononga zokutira pamwamba. Sungani nsalu kutali ndi zinthu zakuthwa. Pamapulogalamu otsetsereka, lingalirani magiredi odzaza a PTFE kapena mafuta okhazikika.
5. Kuyendera nthawi zonse ndi kusintha
Chitani zosamalira mwachizolowezi ndikuwunika miyezi itatu iliyonse kuti zigwire bwino ntchito. Pamizere yayikulu yopangira, konzani zotsalira kuti mugwiritse ntchito mosinthana. Kuzindikira koyambirira kwa kavalidwe kumateteza kulephera kowopsa.
Kufananiza kwa Moyo Wautumiki kwa Zochitika Zisanu ndi Zimodzi Zogwiritsa Ntchito
Gome lotsatirali likufotokozera mwachidule moyo wautumiki womwe ukuyembekezeka kutengera zenizeni zapadziko lonse lapansi kuchokera kwa makasitomala a Aokai PTFE .
Ntchito Scenario
Zogwirira Ntchito & Kupsinjika
Moyo Wautumiki Woyembekezeredwa
Kuphika Chakudya
Kutentha ≤260 ° C; kukhudzana ndi mafuta; zabwino kwambiri zopanda ndodo, zosavuta kuyeretsa
Kutalika - Ntchito zokhazikika (ma tray ophika) zimatha miyezi ingapo osawonongeka
Malamba a Industrial Conveyor
200-260 ° C; kukangana kosalekeza zakuthupi ndi kukangana kwamakina
Wapakati - Kulephera makamaka chifukwa cha kuvala ndi kusweka; pafupifupi miyezi 6-18 kutengera ntchito
Kusindikiza Kutentha & Kuwotcherera
Kutentha kwapakati pa 200-300 ° C; kukhudzana pafupipafupi ndi mitu yosindikiza
Nthawi yayitali - Imakhala ngati yatsopano pambuyo pa 7 kuzungulira pa 190 ° C kukanikiza kwakanthawi kotentha kotentha. Kupaka peel ndiye ngozi yaikulu
Chemical Anti- dzimbiri
Amphamvu zidulo, alkalis, organic solvents; zina pansi pa madzi kapena chinyezi chambiri
Kutalika kwambiri - Mlandu wothandiza: kuyika mapaipi kunagwira ntchito kwa zaka 3 pansi pa 320 ° C nthunzi; Desulfurization tower mu acidity wamphamvu idakhalabe kwa zaka zitatu - 4x nthawi yayitali kuposa zida za mphira
PV Lamination
~ 150 ° C pansi pa kuthamanga kwambiri; kukhudzana pafupipafupi ndi encapsulant ya EVA yosungunuka
Zochepa - Zotsalira zotsalira ndi kukanikiza kotentha kobwerezabwereza ndizo zimayambitsa zolephera; kawirikawiri 6-12 miyezi
Kugwiritsa Ntchito Zovuta Kwambiri
Kulumikizana mwachindunji ndi ma abrasives (mwachitsanzo, gawo lapansi la ma disc odulira abrasive)
Short - Kutupa kwambiri kumafupikitsa moyo; zimasiyanasiyana ndi kuuma kwa abrasive ndi liwiro; imatha milungu kapena miyezi
Momwe Mungakulitsire Moyo Wautumiki - Maupangiri Othandiza
1. Kusankhidwa koyenera kwa mankhwala
Sankhani makulidwe oyenera, kuluka, ndi zokutira kuti mugwiritse ntchito. Pazovala zapamwamba, sankhani giredi ya PTFE yodzaza kapena nsalu yokhuthala. Kuti mukhale ndi mankhwala, onetsetsani kuti mwalowa m'mimba ndipo mulibe mapini.
2. Kukhazikitsa kokhazikika
Pewani kumangika kwambiri poika malamba onyamula katundu.
Gwiritsani ntchito mainchesi akulu kwambiri kuti muchepetse kupsinjika kopindika.
Tsekani m'mphepete ndi silicone sealant kuti mukhale ndi chinyezi.
3. Kusamalira nthawi zonse
Tsukani nsalu nthawi zonse kuti mupewe kuchulukana kotsalira.
Sungani nsalu yosalala komanso yopanda makwinya panthawi yogwira ntchito.
Pazakudya zokhala ndi mafuta ambiri, chepetsa kutentha ndi 10-20 ° C.
4. Kusintha kwanthawi yake - dziwani zizindikiro zochenjeza
Sinthani nsaluyo nthawi yomweyo mukawona:
Kutentha kwambiri (chikasu, browning, blackening)
Brittleness (nsalu imang'ambika ikapindika)
Kupaka matuza kapena peeling kudera lalikulu
Mabowo owoneka kapena mabowo
Osadikirira nthawi yosinthira yomwe yakonzedwa ngati zizindikilo izi zikuwoneka. Nsalu zowonongeka zimatha kuipitsa zinthu kapena kuwononga zida.

Chotsatira chomaliza: Nsalu yotentha kwambiri ya PTFE ndi zinthu zogwira ntchito kwambiri, koma moyo wake weniweni wautumiki umadalira kwambiri momwe umagwiritsidwira ntchito. Kuwongolera kutentha kwambiri (kukhala ≤260 ° C), pewani ming'alu yakuthwa, yeretsani pafupipafupi, ndikusintha mukangoyamba kumene matuza kapena achikasu. Pazinthu zofunikira ngati mankhwala odana ndi dzimbiri, nsalu ya PTFE imatha kupitilira zaka zambiri.
Aokai PTFE imapereka chithandizo chaukadaulo kukuthandizani kusankha nsalu yoyenera ndikukulitsa moyo wake. Lumikizanani nafe ndi zambiri zamapulogalamu anu.
Zomwe zili pamwambazi zimaperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.
Timapereka zinthu zambiri kuphatikizapo nsalu za PTFE zotentha kwambiri, matepi a PTFE otentha kwambiri, malamba a mesh PTFE, malamba opanda msoko a makina omangira, nsalu za PTFE za mbali imodzi, malamba osamva kutentha kwambiri ndi nsalu za fiberglass. Khalani omasuka kulumikizana nafe kuti mumve zambiri zazinthu zamalonda, malangizo ogwiritsira ntchito komanso mayankho osinthidwa mwamakonda.
Zambiri zamalumikizidwe
Timatsatira filosofi ya ukatswiri ndi umphumphu, ndipo tadzipereka kupereka mayankho amodzi ndi ntchito zoganizira makasitomala onse.
