Kodi PTFE High-Temperature Fabric Imagwira Bwanji Kugwedezeka kwa Matenthedwe?

M'mafakitale ambiri, Nsalu za PTFE sizimawonetsedwa ndi kutentha kokhazikika. Zimakhala ndi kusintha kwa kutentha kwachangu - kuchokera mufiriji kupita ku uvuni, kuchokera ku makina osindikizira otentha kupita ku mpweya wozungulira, kapena kuchoka ku chosindikizira kutentha kupita kumalo ozizira. Izi zimatchedwa kutentha kwa kutentha.

Funso ndilakuti: kodi PTFE nsalu yotentha kwambiri imatha kupulumuka mobwerezabwereza, kutentha kwachangu kusinthasintha popanda kusweka, kusokoneza, kapena kutaya ntchito?

Yankho limadalira kutentha kwa kutentha. M'kati mwa malire ake ogwirira ntchito, nsalu ya PTFE imachita bwino kwambiri. Koma kukankhira pamwamba kwambiri, ndipo zokutira zidzalephera.

Aokai PTFE yayesa kukana kugwedezeka kwamafuta pamitundu yathu yonse. Bukhuli likufotokoza kusiyana kwa kutentha komwe kuli kotetezeka, momwe zinthuzo zimagwirira ntchito, ndi zomwe tiyenera kupewa.

Kulekerera Kusiyanasiyana kwa Kutentha - Kodi Otetezeka Ndi Chiyani?

1. Nthawi zambiri ntchito (-70°C mpaka 260°C)

Kuthamanga kwapang'onopang'ono kwapang'onopang'ono mkati mwamtunduwu sikungawononge zowonongeka kwa nsalu. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo kusinthana pafupipafupi pakati pa kusungirako kuzizira pa -50 ° C ndi makina osindikizira otentha pa 260 ° C. Zomwe zimakula ndikugwirizanitsa, koma zokutira za PTFE zimakhalabe ndipo gawo lapansi la fiberglass silimang'ambika.

Chitsanzo: Zipangizo zowumitsa zowumitsira kuzizira kumene lamba amasinthasintha pakati pa kuzizira kwambiri (-40°C) ndi uvuni wowumitsa (150°C). Nsalu za PTFE zimagwira izi tsiku lililonse.

2. Kusiyana kwa kutentha kwambiri (kuzungulira 250°C delta)

Nsalu zapamwamba za PTFE zimatha kupirira kutentha kwakukulu - mwachitsanzo, kumizidwa nthawi yomweyo m'madzi ozizira a 10 ° C pambuyo pa 260 ° C (kutsika kwa 250 ° C). Chophimbacho sichidzang'ambika kapena kung'ambika pambuyo pobwerezabwereza. Izi zatsimikiziridwa ndi kuyesa kwa Aokai PTFE .

3. Malo oopsa - pamwamba pa 300 ° C

Chiwopsezo cha kuwonongeka chimakwera kwambiri ngati kusiyana kwa kutentha kukukulirakulira, monga kuzizira kofulumira kuchokera ku kutentha kopitilira 300 ° C. Nsaluyo ikadutsa 300 ° C (pafupi ndi malo osungunuka a PTFE a 327 ° C), zokutira zimakhala zosungunuka komanso zofooka mwamakina. Kuzizira kwadzidzidzi ndiye kumayambitsa kuchepa kwakukulu ndi kusweka.

Mfundo Yogwirira Ntchito - Gawo laling'ono vs

Kutentha kwa kutentha kumatsimikiziridwa ndi zinthu zowonjezera za gawo lapansi la fiberglass ndi zokutira za PTFE.

1. Fiberglass gawo lapansi - msana wokhazikika

• Malo ochepetsera pamwamba pa 800 ° C

• Kukula kwamafuta ochepa kwambiri (pafupifupi 5 × 10⁻⁶/°C)

• Osauka matenthedwe madutsidwe

Izi zikutanthauza kuti ulusi wagalasi sukula kapena kutsika kwambiri ndi kutentha. Amakhala ndi miyeso yokhazikika pansi pa kugwedezeka kwamafuta ndipo amakana kusweka kwa kupsinjika bwino. Gawo lapansi si ulalo wofooka.

2. Kupaka kwa PTFE - cholepheretsa

• Coefficient of thermal expansion ndi pafupifupi 30 mpaka 40 nthawi ya fiberglass (100-150 × 10⁻⁶/°C)

• Pakutentha kofulumira ndi kuziziritsa, zokutira zimakula ndipo zimakhazikika kwambiri kuposa gawo lapansi

• Izi zimabweretsa kupsinjika kwakukulu pamawonekedwe olumikizana

Chifukwa chake imagwirabe ntchito: Chophimba cha PTFE ndi choonda (nthawi zambiri 10-30 μm) komanso chosinthika. Njira ya impregnation imamangiriza mwamphamvu ku fiberglass. Mkati mwa kutentha kwanthawi zonse, zokutira zimatha kutambasula ndikuchira popanda kusweka. Pakutentha kwambiri kapena kupanga kosapanga bwino, kupsinjika kumaposa mphamvu ya zokutira.

Chidziwitso cha Aokai PTFE: Nsalu yathu yapamwamba kwambiri imagwiritsa ntchito mapasidwe angapo, kulola PTFE kulowa mkati mwa fiberglass weave. Izi zimapanga 'nangula' wamakina omwe amalimbana ndi delamination panthawi yanjinga yotentha - kusiyana kwakukulu kuchokera ku zokutira zotsika kwambiri zomwe zimangokhala pamwamba.

Zinthu Zofunika Kwambiri Zomwe Zimakhudza Kukaniza Kutentha Kwambiri

Sikuti nsalu zonse za PTFE ndizofanana. Zinthu zitatu zimatsimikizira momwe chinthu china chimatha kupirira kutentha kwa njinga.

1. Ukadaulo wopanga - nkhani zamtundu wa impregnation

Nsalu zapamwamba zimakhala ndi njira zambiri zoyamwitsa komanso zopangira sintering . PTFE imalowa mkati mwa mipata ya ulusi, ndikupanga chokhazikika chokhazikika. Chomangira ichi 'chotsekeredwa' chimakana delamination panthawi yotentha.

Zogulitsa zotsika zimagwiritsa ntchito zokutira zachiphaso chimodzi. PTFE imangokhala pamwamba. Pakusintha kwa kutentha kwachangu, zokutirazo zimatuluka ngati zomata zotayirira.

2. Kupaka makulidwe - kuonda ndi bwino

Zovala zowonda zimasintha bwino kusinthika kwa gawo lapansi. Chophimba cha 5-10 μm chidzasinthasintha ndi ulusi wagalasi. Chophimba chokhuthala cha 30-50 μm ndi cholimba komanso chotheka kusweka.

3. Gawo la gawo lapansi - zokhotakhota wandiweyani, ma filaments amphamvu kwambiri

Nsalu zolukidwa kwambiri, zolimba kwambiri zokhala ndi ma void ochepa komanso okhazikika bwino. Amaperekanso malo ochulukirapo a PTFE anchoring. Nsalu zotsika, zokhotakhota zotseguka zimakhala zosavuta kuphulika komanso kutaya zokutira pansi pa njinga yamoto.

Kukhalitsa mu Ntchito Zothandiza - Zomwe Muyenera Kuyembekezera

Pazida zomwe zimafunikira kutentha ndi kuziziritsa mobwerezabwereza, monga:

• Zosindikizira kutentha (kuzungulira masekondi angapo aliwonse)

• Mapadi odzipatula otenthetsera

• Zida zoteteza kuwotcherera

• Zida zoyendetsa njinga zachisanu

Nsalu zotentha kwambiri za PTFE zimatha kupirira matenthedwe masauzande masauzande ambiri popanda kulephera.

1. Momwe kulephera kumachitikira - kutopa pang'onopang'ono

Kulephera sikungochitika mwadzidzidzi. Zimachitika pang'onopang'ono:

1. Ming'alu yaying'ono imakula mu zokutira za PTFE (zosawoneka ndi maso)

2. Kupaka kumayamba kutaya katundu wopanda ndodo m'madera opanikizika

3. Kuwombera m'mphepete kumawonekera pamikwingwirima kapena m'mphepete

4. Kupaka delaminates, poyera fiberglass

5. Magalasi a fiberglass amaphulika ndi misozi ya nsalu

Kuyang'ana pafupipafupi (zambiri zingapo zilizonse) kumatha kuzindikira kusweka koyambirira kusanachitike ngozi yowopsa.

Zolemba Zogwiritsa Ntchito & Zovuta Zodziwika - Zomwe Muyenera Kupewa

Ngakhale nsalu yabwino kwambiri ya PTFE ikhoza kuwonongedwa ndi ntchito yosayenera.

1. Osazizira kwambiri chifukwa cha kutentha kwambiri (>300 ° C)

Ngati nsaluyo imatenthedwa pamwamba pa 300 ° C (pafupi ndi malo osungunuka a 327 ° C) ndiyeno itakhazikika mwadzidzidzi (mwachitsanzo, kuzimitsa m'madzi kapena kungoyang'ana kutentha kwa mpweya), chophimba cha PTFE chidzachepa kwambiri ndipo chikhoza kuyamba kuwola. Izi zimabweretsa kusweka, kusenda, ndi kuwonongeka kosatha . Ntchitoyi iyenera kuletsedwa kwathunthu.

Mphepete mwachitetezo: Kwa moyo wautali, sungani kutentha kwa nsalu pansi pa 260 ° C. Maulendo ang'onoang'ono mpaka 280-300 ° C amatha kupirira magiredi ena, koma osachita mantha chifukwa cha kutenthako.

H3: Khalani kutali ndi zinthu zakuthwa komanso kupindika kwambiri

Kutenthedwa kwa kutentha pamodzi ndi kuwonongeka kwa makina - monga ma creases, scratches, kapena makola akuthwa - kumathandizira kwambiri kuwonongeka. Chophimba chophwanyika chafooka kale; matenthedwe njinga ndiye propagates ming'alu kuchokera zikande.

Kuchita bwino: Yang'anani nsalu nthawi zonse. Bwezerani ngati muwona zikwatu zowoneka, zopindika, kapena kukweza m'mphepete kupalasa kotentha kusanapitirire.

Chidule - Malangizo a Thermal Shock a PTFE Fabric

Aokai PTFE imapanga nsalu yotentha kwambiri ya PTFE yokhala ndi mapasi angapo olowera ndi zokutira zopyapyala zokometsedwa kuti zisamatenthedwe ndi kutentha. Pamapulogalamu omwe ali ndi kutentha kwambiri panjinga (monga kuzirala kofulumira kuchokera pa 260°C), titumizireni kuti mumve zambiri za mayeso ndi zomwe mungakonde.

Zomwe zili pamwambazi zimaperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.

Ngati mukufuna zambiri zokhudzana ndi ndondomeko, zochitika zamagwiritsidwe ntchito ndi njira zothetsera makonda amtundu wathu wonse, kuphatikizapo nsalu za PTFE zotentha kwambiri, matepi a PTFE apamwamba, malamba a PTFE, malamba a makina osakanikirana, nsalu imodzi ya PTFE, lamba wotentha kwambiri wosagwira ntchito, malamba osamva kutentha kwa magalasi, chonde kukhudzana ndi magalasi osasunthika:

• Bambo Guo: +86 18944819998

• Bambo Liu: + 86 13705266308

Timatsatira filosofi yautumiki ya ukatswiri ndi kukhulupirika, ndipo timayesetsa kukupatsirani mayankho okhazikika ndi ntchito zoganizira.
