Zotsatira Zamtengo Wozizira pa Tepi ya PTFE

Monga opanga oyambirira a PTFE matepi otentha kwambiri, Jiangsu Aokai New Materials apa akulongosola zotsatira za njira zoziziritsira ndi kuzizira kwa matepi ochiritsidwa a PTFE.

I. Zofunika za PTFE Crystallization Makhalidwe ndi Kuzirala Rate Regulation

The PTFE gawo lapansi la anachiritsa mkulu-kutentha tepi wa theka-crystalline polima, amene amakumana mofulumira crystallization pa kuzirala pambuyo sintering. Kwenikweni, kuzirala mlingo ndi pachimake ndondomeko chizindikiro kulamulira crystallinity wa PTFE mkulu-kutentha tepi: pang'onopang'ono kuzirala kumabweretsa apamwamba crystallinity, pamene mofulumira kuzirala kumabweretsa m'munsi crystallinity.

II. Zotsatira za Kuzizira Pang'onopang'ono pa PTFE Matepi Otentha Kwambiri

Chikoka pa  Kupsinjika Kwamkati Kuzizira pang'onopang'ono kumatha kuchepetsa kupsinjika kotsalira kotsalira mkati mwa tepi. Pamene tepiyo itakhazikika mwachibadwa mkati mwa ng'anjo, PTFE masanjidwewo ndi galasi CHIKWANGWANI chigoba amakhala ndi nthawi yokwanira kusintha shrinkage kusiyana kudzera mu unyolo unyolo kupuma, kupewa ndende kupsinjika maganizo.

Njira yomwe anthu ambiri amatengera ndikuziziritsa tepiyo mwachilengedwe mu ng'anjo mpaka 150-200 ℃ musanayitulutse kuti iziziziritsa. Kuzizira pang'onopang'ono kumeneku kumachepetsa kupsinjika kwamkati bwino ndikulepheretsa kutikita delamination ndi kusweka.

Chikoka pa Dimensional Stability  Kuzizira pang'onopang'ono kumathandizira kwambiri kukhazikika kwa mawonekedwe. Pakuzizira pang'onopang'ono, unyolo wa ma molekyulu a PTFE amakonzekera m'magalasi owoneka bwino a kristalo mokwanira, kupanga kristalo wapamwamba kwambiri komanso njere za kristalo zopangidwa bwino, zomwe zimatsimikizira miyeso yokhazikika yomaliza.

Kutsika pang'ono kwa kutentha kudzachitika pansi pa kutentha kwakukulu mukugwiritsa ntchito kwenikweni, choncho tikulimbikitsidwa kusunga malire a 1% -2% panthawi yogwiritsira ntchito. Kuziziritsa pang'onopang'ono kumathandizira kuchulukira kosalekeza kotsalira pang'ono.

Chikoka pa Zomatira Magwiridwe  Kuziziritsa pang'onopang'ono kumakhala ndi zotsatira ziwiri pa zomatira. Kumbali imodzi, imalola kuti zomatira zimalize kulumikizana ndikupumula kwathunthu, ndikusunga mphamvu zomangira zokhazikika. Kumbali inayi, crystallinity yapamwamba imawonjezera kukhazikika kwa gawo lapansi la PTFE, zomwe zimapangitsa kuti pakhale kupsinjika kwakukulu pamawonekedwe omangirira pansi pa mphamvu yopukutira.

III. Zotsatira za Kuzizira Kwambiri pa matepi a PTFE Otentha kwambiri

     Chikoka pa Kupsinjika Kwamkati  Kuzizira kofulumira ndizomwe zimayambitsa kupsinjika kwamkati. Kuzimitsa mwachindunji pambuyo sintering kumapanga kusiyana kwakukulu kwa kutentha pakati pa PTFE masanjidwewo ndi galasi CHIKWANGWANI chimango, kutulutsa nthawi yomweyo shrinkage nkhawa ndi mosavuta kupanga ming'alu zabwino.

Chigawo chapamwamba chimachepa ndipo chimauma mofulumira pamene gawo lamkati limakhalabe likukulitsidwa, kupanga chikhalidwe cha kutentha kwa kutentha kwa kunja ndi kupanikizika kwamkati, zomwe zimayambitsa mwachindunji kusweka kwa tepi.

Chikoka pa Dimensional Stability  Kuzizira kofulumira kumasintha nsonga ya crystallization kuti ichepetse kutentha ndikuchepetsa crystallinity ndi mawonekedwe osakwanira a kristalo. Tepiyo imakhala m'malo oundana osakhazikika pambuyo pozimitsa. Sekondale crystallization ndi pambuyo-shrinkage zikhoza kuchitika pansi pa kusintha kwa kutentha, kumabweretsa kupatuka pang'onopang'ono dimensional.

Mphamvu pa Adhesive Performance  Kuzizira mwachangu kumalepheretsa kulumikizana kwathunthu kwa zigawo zomatira. Zomatirazo zimawumitsidwa musanapange maukonde athunthu olumikizana, zomwe zimapangitsa kuchepa kwa mphamvu yomangira komanso kukana kutentha.

Pansi pa njinga yozizira ndi yotentha mobwerezabwereza, kusiyana kwa kutentha kwapakati pakati pa gawo lapansi la PTFE ndi zomatira kumapangitsa kuti pakhale kupsinjika kwapakati pa nkhope, kufulumizitsa ukalamba womatira ndikumangirira, ndikufooketsa kulimba kwa kukhuthala.

IV. Kuyerekeza Njira Zosiyanasiyana Zozizirira

 

Nthawi zambiri, kuziziritsa pang'onopang'ono ndi yunifolomu ndiyo mfundo yofunikira pakuchiritsa pambuyo pochiritsa matepi a PTFE otentha kwambiri. Ndibwino kuti mutengere kuziziritsa kwachilengedwe mu ng'anjo mutatha kuyatsa, ndikutulutsa matepi kuti muzizire mpweya mpaka kutentha kutentha kutsika pansi pa 150-200 ℃. Kuzizira kosagwirizana panthawi yopanga kumayambitsa kufooka ndipo pamapeto pake kuwononga mtundu wazinthu.

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

Ngati mukufuna kudziwa mwatsatanetsatane magawo, mawonekedwe ogwiritsira ntchito ndi mayankho makonda azinthu zathu zonse kuphatikiza nsalu ya PTFE yotentha kwambiri, tepi ya PTFE yotentha kwambiri, lamba wotentha kwambiri wa PTFE, lamba wamakina osakanizika, mbali imodzi ya PTFE nsalu, lamba wosamva kutentha kwambiri wa PTFE, lamba wosamva kutentha kwa fiberglass ndi kutentha kwambiri.

Nthawi zonse timatsatira mfundo za ukatswiri ndi kukhulupirika, ndipo ndi mtima wonse timakupatsirani mayankho okhazikika komanso ntchito zoganizira.
