Kapangidwe kagawo kakang'ono ka nsalu ya PTFE High-Temperature: Kodi Pali Kusintha Pakati Pakati pa PTFE Coating ndi Fiberglass Substrate?

Jiangsu Aokai New Materials, katswiri wopanga nsalu za PTFE zotentha kwambiri, amakupatsirani chidziwitso chakuya. Monga zinthu zophatikizika kwambiri, mawonekedwe ang'onoang'ono amtundu wa PTFE kutentha kwambiri ndikofunikira pakukana kwake kutentha, mphamvu ya peel ndi kusinthasintha. Popanga nsalu ya PTFE yotentha kwambiri, pali gawo  lofunikira losinthira pakati pa zokutira za PTFE ndi gawo lapansi la fiberglass. Popanda kusanjikiza kosinthika kumeneku, kukhulupirika kwadongosolo kwa nsalu ya PTFE yotentha kwambiri sikungakwaniritsidwe.

Kupyolera mu kusanthula kwapang'onopang'ono kwapang'onopang'ono, kusinthaku sikupangidwa ndi mankhwala amodzi, koma mawonekedwe ophatikizika amapangidwa kudzera munjira zingapo zosinthira thupi ndi mankhwala. Kapangidwe kake ndi kapangidwe kagawo kakusintha kumafotokozedwa motere:

1. Silane Coupling Agent Bonding Layer

Magalasi a fiberglass osasamalidwa sangathe kulumikizana mwachindunji ndi utomoni wa PTFE. Chifukwa chake, nsalu ya fiberglass iyenera kusinthidwa ndi ma silane coupling agents popanga. Mapeto amodzi a ophatikizana amakhudzidwa ndi magulu a silanol (Si-OH) pamtunda wa fiberglass, pomwe mbali ina ili ndi magulu okhudzidwa omwe ali ndi kuyanjana kwakukulu kapena kuyanjananso ndi fluororesins. Kugwira ntchito ngati mlatho womangira mankhwala pakati pa mafupa a fiberglass ndi zokutira za PTFE, wosanjikizawu umapereka maziko olimba amankhwala pakuyamwa kwathunthu.

2. Hot-Melt Adhesive Intermediate Layer

Pakuwunika kwapang'onopang'ono kwa nsalu zapamwamba za PTFE zotentha kwambiri, mawonekedwe osinthika a gradient okhala ndi PFA (Perfluoroalkoxy alkane) kapena FEP (Fluorinated Ethylene Propylene) amatha kuwonedwa bwino pakati pa zokutira za PTFE ndi gawo lapansi la fiberglass. Panthawi yotentha kwambiri, ma fluoroplastics osungunukawa amakhala ngati zomatira zamkati zosungunuka, kulowa ndi kukulunga mitolo ya fiberglass kuti apange gawo lopitilira. Izi wosanjikiza wapakatikati bwino kupewa ❖ kuyanika delamination pansi mobwerezabwereza kupinda ndi kusinthasintha zinthu.

3. Makina Olumikizirana Makina

Nsalu ya PTFE yotentha kwambiri imapangidwa kudzera munjira zingapo zoyatsira ndi zokutira. Tizilombo tating'ono, PTFE emulsion likulowerera mu micron-kakulidwe pores opangidwa ndi warp ndi weft kuluka nsalu fiberglass. Pambuyo sintering ndi kuchiritsa, olimba PTFE utomoni amapanga atatu azithunzithunzi makina nangula dongosolo ndi nsalu CHIKWANGWANI. Kapangidwe kameneka kamene kamakhala kamene kamapereka chithandizo chodalirika cha makina, kuonetsetsa kukhazikika kwa mawonekedwe ndi ntchito zotsutsana ndi delamination muutumiki wautali.

4. Chiyankhulo cha Gradient Buffer

Kupaka kwa PTFE ndi magalasi a fiberglass amakhala ndi ma coefficients osiyanasiyana akukula kwa matenthedwe, komwe kumapangitsa kupsinjika kwamkati mosavuta ndikuwotcha mwachangu ndi kuzizira. Nsalu yotentha kwambiri ya PTFE imakhala ndi mawonekedwe ozungulira: dera lomwe lili pafupi ndi fiberglass lili ndi zomatira zosagwira kutentha ndi FEP, pomwe chiyero cha PTFE chimawonjezeka pang'onopang'ono kumtunda. Kapangidwe ka gradient kameneka kamateteza kupsinjika kwamatenthedwe pakatentha kwambiri komanso kumapewa kusweka kwa zokutira.

5. Substrate Pretreatment Interface

Musanapange zigawo zosinthira pamwambapa, nsalu ya fiberglass iyenera kutenthedwa ndi kutentha kwambiri ndikuchotsa zinthu zopangira nsalu ndi zonyansa. Gawo loyambirira lothandizirali likuwonetsa magulu a silanol omwe akugwira ntchito pamalo opangira ulusi, ndikupereka mawonekedwe oyera komanso osakanikirana ndi mankhwala ophatikizana komanso kulowa kwa utomoni.

Mapangidwe amtundu wa nsalu za PTFE zotentha kwambiri zimapanga dongosolo lathunthu lokhala ndi zomangira zolimba, kulowera kwa gradient ndi utomoni wopanda ntchito pamwamba . Kupindula ndi magawo osiyanasiyana osinthika ophatikizidwa ndi kutsekeka kwakuthupi ndi kulumikizana ndi mankhwala, zinthuzo zimasungabe katundu wabwino kwambiri wotulutsa komanso kukana kwa dzimbiri kwa PTFE, pomwe zimapeza mphamvu zolimba komanso kukana kutopa.

Zomwe zili pamwambapa zimaperekedwa ndi Jiangsu Aokai New Material Technology Co., Ltd.

Timapereka zinthu zosiyanasiyana kuphatikizapo PTFE nsalu yotentha kwambiri, tepi yotentha kwambiri ya PTFE, lamba wa PTFE wotentha kwambiri, lamba wa makina osakanikirana, mbali imodzi ya PTFE yokutidwa ndi nsalu, lamba wonyamula kutentha kwambiri komanso nsalu ya fiberglass yosagwira kutentha kwambiri. Kuti mumve zambiri zamalonda, mayankho ogwiritsira ntchito ndi ntchito zosinthidwa makonda, chonde titumizireni:
