M'ndandanda wazopezekamo

M'zomera zamankhwala, mapaipi ndi zotengera zimakumana ndi kuukira kosalekeza kuchokera kuzinthu zaukali - ma asidi amphamvu, ma alkali otentha, zosungunulira organic, ndi nthunzi. PTFE tepi ndi njira wamba yothetsera dzimbiri, sanali ndodo, ndi kusindikiza chitetezo. Koma kusankha tepi yoyenera sikophweka monga kusankha kutentha kwapamwamba kwambiri.

Aokai PTFE yapereka tepi ya PTFE yogwiritsa ntchito mankhwala kwazaka zambiri. Bukhuli likufotokoza mawonekedwe atatu a tepi ya PTFE, njira zosankhidwa zoyambira (kutentha, media media, zofunikira zamakina), ndi malangizo omanga ofunikira.

Mapangidwe Atatu a PTFE High-Temperature Tepi

Ntchito yonse ya tepi yamalonda ya PTFE imatsimikiziridwa ndi zigawo zitatu:

Structural Layer	Zida Zogwirizana	Zokhudza Kusankha Kwazinthu
Pamwamba ntchito wosanjikiza	Filimu yoyera ya PTFE / PTFE-yopangidwa ndi fiberglass nsalu	Imalamulira katundu wopanda ndodo, kukana kwa mankhwala, komanso kukana kutentha kwambiri
Kulimbikitsa gawo lapansi	Palibe (filimu yoyera) / Fiberglass nsalu / Aramid nsalu	Imatsimikizira mphamvu zamakina, kukana kwamphamvu, komanso kukana nkhonya
Zomatira wosanjikiza	Silicone PSA, Acrylic PSA, PSA yochokera ku Rubber	Amayika malire a kutentha kwapamwamba ndi kukana kwa mankhwala a tepi yonse; kawirikawiri ulalo wofooka kwambiri wa magwiridwe antchito

Kuzindikira kofunikira: Ngakhale PTFE yokha imatha kugwira ntchito mokhazikika kuyambira -190 ° C mpaka 260 ° C kwa nthawi yayitali, zomatira ndizolepheretsa ntchito . Sankhani zomatira potengera malo enieni a utumiki, osati malo a PTFE okha.

Zosankha Zoyambira ndi Mfundo Zofananira

1. Kutentha kwa ntchito - kusankha zomatira ndizofunika kwambiri

Kutentha Kusiyanasiyana	Analimbikitsa zomatira	Chifukwa chiyani?
200 ° C - 260 ° C (nthawi yayitali)	Silicone PSA (yofunikira)	Njira yokhayo yomatira yomwe imakhalabe yokhazikika pamtundu uwu; zotsalira zochepa pambuyo peeling
120 ° C - 180 ° C ndi zosungunulira zapamwamba & kukana mafuta	Kutentha kwambiri kwa acrylic PSA	Kulumikizana mwamphamvu kuposa silikoni, koma kumalephera mwachangu pa 260 ° C
Pansi pa 100 ° C	Ma acrylics okhazikika kapena opangidwa ndi mphira	Zovomerezeka, koma zosowa m'malo opangira mankhwala

Chidziwitso cha Aokai PTFE: Pazogwiritsa ntchito pa 200 ° C+, acrylic PSA sizovomerezeka - imatsitsa, kufewetsa, ndikuyambitsa kusenda kwa tepi. Silicone ndiye chisankho chokhacho chotheka.

2. Chemical media - kuyanjana pakati pa zomatira ndi gawo lapansi

Zosanjikiza zogwira ntchito za PTFE zimakhala ndi pafupifupi kukana dzimbiri kwachilengedwe chonse (kupatula zitsulo zosungunuka za alkali ndi mpweya wotentha kwambiri wa fluorine). Komabe, media media imalowa m'mphepete mwa tepi ndikuwononga mwachindunji zomatira.

Chemical Media	Analimbikitsa zomatira	Chenjezo
Ma asidi amphamvu achilengedwe (HCl, H₂SO₄ ≤80%), ma alkali amphamvu (NaOH), brine, nthunzi wamadzi	Silicone PSA	Kulekerera kwabwino; amapanga zotchinga zodzitchinjiriza
Ma organic solvents (ketoni, esters, benzene, toluene), mafuta, mafuta, amphamvu oxidizing acid (HNO₃, concentrated H₂SO₄), glacial acetic acid.	Acrylic PSA (kalasi yosasunthika)	Silicone amatupa mu zosungunulira organic; acrylic akulimbikitsidwa, koma tsimikizirani kutentha (nthawi zambiri ≤150 ° C)
Mpweya wotentha kwambiri + asidi wambiri / alkali (kuwonetseredwa mosinthana)	Silicone yosinthidwa PSA + yokhotakhota yamitundu yambiri	Mkhalidwe wovuta kwambiri - silikoni imatha kukhala ndi hydrolyze; limbitsani ndikumangirira kwamitundu yambiri

Pakutentha kopitilira 150°C ndi zosungunulira organic: Gwiritsani ntchito makina okonza kapena glue-free heat-shrink pure PTFE tepi/chubu.

Zochitika Zogwiritsira Ntchito ndi Kusankhidwa Kwagawo Logwirizana

Ntchito Scenario	Substrate yovomerezeka	Chifukwa
Chitoliro chakunja cha khoma lodana ndi dzimbiri & zokutira zoletsa ndodo (letsani kuchulukira kwa zinthu za splash)	Nsalu yamphamvu kwambiri ya PTFE-yokutidwa ndi fiberglass (yabulauni/yakuda)	Zosavala, zosagwedera; makulidwe 0.13-0.25mm; oyenera mapiringidzo mobwerezabwereza, conformability kwambiri
Khoma lamkati la chombo & flange pamwamba odana ndi ndodo liner	Kanema wa Transparent pure PTFE	Yosalala kwambiri yopanda ndodo, palibe chiwopsezo chowotcha ulusi; yabwino kwa malo athyathyathya ndi aakulu okhotakhota
Kusakaniza shaft & roller wrapping	PTFE fiberglass nsalu yokhala ndi zomatira zapamwamba za silikoni	Imathandizira kukhazikika kwamphamvu; gawo lapansi la fiberglass limapereka mphamvu zolimba kwambiri, limapewa kupunduka panthawi yozungulira
Kusindikiza ulusi ndi kusintha gasket	Tepi yopangidwa ndi filimu yoyera ya PTFE	Amagwiritsa ntchito katundu wa PTFE ozizira kuti akwaniritse mipata; tepi wopanda fiberglass ndiyofunika
Mabowo & magalasi owonera a matanki amphamvu osungira asidi	Filimu yoyera ya PTFE / nsalu ya fiberglass yokhala ndi zomatira zosagwirizana ndi mankhwala	Filimu yoyera imapatula media zowononga; nsalu ya fiberglass imawonjezera kulimba; ma lap joints amafuna multilayer reinforcement

Zomangamanga Zovuta ndi Malangizo a Chitetezo

1. Kukonzekera kwapamwamba - maziko a mgwirizano

Kuchotsa mafuta kwathunthu, kuchotsa dzimbiri, ndi kuyanika. Pukutani pamwamba ndi acetone kapena mowa ndikutsatiridwa ndi kuphika kwamoto mwachangu kuti muchulukitse mphamvu yolumikizana. Izi zimachotsa zowononga ndikuyambitsa zitsulo pamwamba kuti zigwirizane kwambiri.

2. Zigawo zopindika ndi zopindika

zosachepera 2-3 Zosanjikiza zimafunikira kuti chitetezo chamankhwala chitetezedwe ndi 50% pagulu lililonse. Mapeto a tepi ayenera kulimbikitsidwa ndi tepi yofananira ya PTFE kapena zomangira zitsulo zosapanga dzimbiri kuti zisavumbuluke pambuyo polowera zomatira ndi media.

3. Chitetezo pachimake - nthawi yopewera tepi ya PTFE palimodzi

Pazinthu zotsatsira zotsatirazi, matepi onse okhala ndi zomatira organic ndi osatetezeka :

Hydrogen fluoride (HF)
Kutentha kwambiri alkali wamphamvu (> 80%)
Chlorine trifluoride (ClF₃)

Njira ina: Sinthani ku PTFE yathunthu kapena zotchingira zokhazikika (zopanda zomatira).

4. Njira zotsutsa-static ndi kuphulika-kuphulika

Ngati payipiyo ili ndi zinthu zoyaka moto ndipo kuchulukidwa kosasunthika kungachitike, sankhani tepi yotsutsana ndi malo amodzi (kawirikawiri wakuda wakuda wokhala ndi mpweya wa carbon, resistivity 10⁶-10⁹ Ω) kuti muwononge static charge bwinobwino.

Ngati chilengedwe chanu ndi ...	Sankhani...	Pewani...
200-260 ° C, zidulo / alkali / nthunzi	Silicone PSA + fiberglass gawo lapansi	Acrylic PSA (idzasokoneza)
120-150 ° C, organic solvents	Acrylic PSA (yosagwirizana ndi zosungunulira)	Silicone PSA (kutupa mu zosungunulira)
> 150 ° C, zosungunulira organic	Filimu yoyera ya PTFE + kukonza makina	Tepi iliyonse yomatira
HF, kuwira > 80% alkali, ClF₃	PTFE-yokha lining (palibe zomatira)	Tepi iliyonse yokhala ndi zomatira organic
Zida zoyaka moto, chiopsezo chokhazikika	PTFE tepi ya Anti-static (yodzazidwa ndi mpweya)	Non-conductive standard tepi
Kusindikiza ulusi, kudzaza mipata	Anajambula tepi ya filimu ya PTFE	Fiberglass-reinforced tepi

Aokai PTFE imapereka matepi athunthu a PTFE opangira mankhwala - silikoni PSA yautumiki wotentha kwambiri wa asidi/alkali, acrylic PSA ya kukana zosungunulira, ndi magiredi odana ndi malo amodzi. Lumikizanani nafe ndi media media, kuchuluka kwa kutentha, ndi zofunikira zamakina kuti musankhe mogwirizana.
