Momwe Mungapewere Mavuto Omwe Amadza chifukwa cha Kukula kwa Matenthedwe mu PTFE High-Temperature Fabric Applications

Nsalu ya PTFE yotentha kwambiri ilibe coefficient of thermal expansion (CTE). Mosiyana ndi zitsulo kapena pulasitiki yolimba, kukula kwake kumakhudzidwa pamodzi ndi nsalu ya fiberglass, PTFE yotsegula, kapangidwe kake, ndi kutentha kwa ntchito.

Kusokonekera kumeneku nthawi zambiri kumabweretsa zovuta zosayembekezereka: malamba omangika omangika, ma gaskets ong'ambika, zigawo zodetsedwa, kapena zomangira zokhotakhota. Kumvetsetsa ndi kupanga kukulitsa kutentha ndikofunikira kuti pakhale ntchito yodalirika yanthawi yayitali.

Aokai PTFE yasanthula machitidwe okulitsa kutentha pamapulogalamu ambiri. Bukuli likufotokoza za CTE zomwe zimayendera ndipo limapereka njira zisanu ndi imodzi zothandiza kupewa zolephera zokhudzana ndi kukulitsa.

Ma Coefficients Odziwika a Kukula kwa Matenthedwe - Dziwani Manambala Anu

1. CTE yoyera ya PTFE

Pure PTFE ili ndi mzere wapamwamba wowonjezera wowonjezera kutentha: pafupifupi 10×10⁻⁵ – 20×10⁻⁵/°C (100–200 ppm/°C) pa kutentha kwa firiji, ndi kusiyanasiyana kosiyana monga kusintha kwa kutentha.

Zofunika kwambiri: PTFE imadutsa kusintha kwa gawo la crystalline pafupifupi 19 ° C ndi 30 ° C , zomwe zimapangitsa kuti voliyumu isinthe mwadzidzidzi 1% -2% . Izi zimafuna chidwi chapadera pakugwiritsa ntchito molondola. Filimu yoyera ya PTFE ya mita imodzi imatha kukula ndi 1-2 cm podutsa kutentha kwachipinda.

2. PTFE nsalu yotentha kwambiri (fiberglass substrate) - mtundu wa CTE

Fiberglass palokha ili ndi CTE yotsika kwambiri ya pafupifupi. 5×10⁻⁶/°C (5 ppm/°C) , yogwira ntchito ngati chimango cholimba choletsa kukula kwa PTFE ndikuchepetsa kwambiri kukulitsa kwamafuta mundege kwa nsalu yomalizidwa. Komabe, kamangidwe kameneka kamapangitsa kuti pakhale kukula kwakukulu kuposa nsalu za fiberglass.

Kukula m'mbali mwa makulidwe ndikofunikira kwambiri chifukwa cha kuchuluka kwa utomoni wa PTFE. Pazolinga zauinjiniya, zosintha zamkati mwandege zokha zomwe zimayikidwa patsogolo.

Mapangidwe Apangidwe Ovomerezeka a Kutalikira Kwamatenthedwe

1. Mphepete zowonjezera zaulere

Mukagwiritsidwa ntchito ngati ma gaskets, matayala otchingira matenthedwe, kapena malo otsetsereka, pewani kukhazikika kwathunthu mbali zonse zinayi. Sungani osachepera m'mphepete mwaulere umodzi kapena ziwiri kuti mulole kutambasuka ndi kutsika kopanda malire.

2. Mabowo okwera otalikirapo

Ngati pakufunika kumangirira bawuti, kulitsani mabowo kapena gwiritsani ntchito mabowo atalitali. Musamangitse mabawuti kwathunthu; onjezani ma gaskets kuti musunge ndalama zocheperako. Izi zimalola kuti zinthuzo zikule komanso ziwonjezeke popanda kupsinjika pamaboliti.

3. Kuyika kwa magawo

Poika malo akuluakulu, gawani nsaluyo kukhala mapanelo osiyana okhala ndi 3-5 mm zolumikizira pakati pa zidutswa, makamaka motsatira utali. Izi zimalepheretsa kukumbatirana kuti zisawonjezeke kwa nthawi yayitali.

Pewani Kukwera Panjinga Kwachangu Kudutsa Pagawo Lofunika Kutentha Kwambiri

PTFE imakhala ndi kusinthasintha kwakukulu kwa voliyumu pafupi ndi kutentha kwa chipinda - makamaka pa 19 ° C ndi 30 ° C gawo losinthira. Ngati zida zimasinthasintha pakati pa kusungirako kuzizira ndi kutentha kozungulira, musamanikize nsalu ya PTFE mwamphamvu kwambiri.

• Ikayikidwa pa kutentha kochepa koma ikagwiritsidwa ntchito kutentha kwakukulu, nsaluyo imatalika (mwachitsanzo, nsalu ya mita imodzi imatambasula mamilimita angapo ikatenthedwa kuchokera 25 ° C mpaka 200 ° C).

• Konzekeretsani zomangira zolimba ndi zolipira zokha (zodzaza masika kapena makina owerengera) m'malo mokhoma molimba.

Lamulo lofunikira: Osalimbanitsa nsalu ya PTFE mwamphamvu firiji ndikuyitenthetsa - kukulitsa kudzapanga mafunde. Osachilimbitsa mwamphamvu pakutentha kwambiri ndikuziziritsa - kucheperako kumang'amba kapena kukulitsa zinthuzo.

Anti-Buckling Design for Overlops and Joints

• Gwirizanani motsatira njira yokulirapo , ndikuwonetsetsa kuti m'lifupi mwake mukupitilira kutalika komwe kumanenedweratu.

• Kwa seams zosokedwa , siyani ndalama zotayirira pa kusokera kwa ulusi. Ngati amangidwa ndi zomatira zotentha kwambiri, sankhani guluu zotanuka kuti mupewe kung'ambika chifukwa chosagwirizana ndi ma coefficients okulitsa.

• Pamasanjidwe amitundu yambiri , pewani kulumikizana kwathunthu. Gwirizanitsani kulumikiza kapena kukonza magawo ndi zingwe zosindikizira kuti mulole kutsetsereka kwa interlayer - kuchotsa matuza ndi delamination.

Kuwongolera Kuvuta kwa Zochitika Zogwirira Ntchito

1. Ntchito lamba wotumizira

Ikani zolumikizira zowongoka kapena zodzaza ndi masika kuti muzitha kumasuka ndi nsalu pa kutentha kwakukulu ndikuchuna pakutentha kotsika. Musamangitse lamba kwambiri kutentha kwakukulu - izi zimabweretsa kuchulukirachulukira panthawi ya kuzizira. Kuvuta kwa lamba kuyenera kukhazikitsidwa pa kutentha komwe kumayembekezeredwa kocheperako.

2. Kutulutsa zingwe ndi mapepala odzipatula

Lalani mosalekeza popanda kukangana. Tetezani pang'ono podzilemera nokha kapena timizere tating'ono tating'ono kumbali imodzi kuti muteteze kuphulika kosatha komwe kumabwera chifukwa chakukula kwamafuta.

Chepetsani Kusokonekera kuchokera ku Kutentha Kwambiri Gradients

Kukula kosagwirizana kumachitika pamene mbali imodzi ya nsaluyo imakhala ndi kutentha kwakukulu pamene ina imakhalabe yozizira, zomwe zimayambitsa nkhondo.

Njira zochiritsira:

• Kuthina kwapang'onopang'ono ndi mafelemu m'malo mopitilira kukanikizana kwa m'mphepete

• Sankhani nsalu zokulirapo, zotalikirana kwambiri ndi fiberglass kuti muchepetse masamba ankhondo

• Khazikitsanitu reverse arching kumbali yotentha ngati kuli kofunikira (ikani nsaluyo kuti iphwanyike pakutentha)

Kuyendera Kwanthawi ndi Kusamalira

Pambuyo panjinga yayitali yotentha, PTFE idzakhala ndi mawonekedwe ozizira otaya , zomwe zimapangitsa kuti pakhale kutalika kokhazikika kapena kufooka komweko.

• Yang'anani nthawi zonse ndikuwongolera milingo yazovuta - malamba angafunike kuyambiranso pambuyo poyambira matenthedwe angapo oyamba.

• Konzani zotupa ndi delamination mwachangu kuti mupewe kupsinjika ndi kung'ambika.

• Kachitidwe kakukulitsa zolemba - ngati lamba nthawi zonse atalikira kupitilira kusintha, angafunike kusinthidwa kapena gawo lina lofananira ndi CTE.

Malingaliro a Aokai PTFE: Pazogwiritsa ntchito panjinga zotentha kwambiri (monga zotengera zotengera uvuni kumayendedwe ozungulira mpaka 250°C kangapo patsiku), timalimbikitsa nsalu yokhala ndi magalasi apamwamba a fiberglass (otsika CTE) komanso kuyang'anira kugwedezeka.

Chidule cha Chidule - Mndandanda wa Mapangidwe Okulitsa Kutentha kwa Matenthedwe

Aokai PTFE imapereka PTFE nsalu yotentha kwambiri yokhala ndi zolembedwa za CTE ndipo imatha kupangira magiredi enaake amtundu wa kutentha kwa pulogalamu yanu. Lumikizanani nafe kuti mupeze mapepala aukadaulo komanso thandizo la mapangidwe a pulogalamu.

Chikalata chaukadaulochi chikuperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.

Ngati mukufuna zakuya zaukadaulo, milandu yogwiritsira ntchito ndi njira zosinthira makonda athu onse opanga zinthu kuphatikiza nsalu za PTFE zotentha kwambiri, matepi a PTFE, malamba a mauna a PTFE, malamba opanda laminator, nsalu za PTFE zambali imodzi ndi malamba onyamula kutentha kwambiri, chonde titumizireni makiyi apansi apa:

• Bambo Guo: +86 18944819998

• Bambo Liu: + 86 13705266308

Timatsatira miyezo yaukatswiri ndi kukhulupirika kuti tipereke mayankho amtundu umodzi komanso chithandizo choganizira pambuyo pogulitsa kwa makasitomala onse.
