Saamaynta Muhiimka ah ee Qaybinta Cabbirka Qaybaha Emulsion ee PTFE iyo Miisaanka Molecular ee Ku Saabsan Caabbiska Xidhashada Maro Fiber Glass

Maro heerkul sare ah oo Teflon ah oo ka timid Jiangsu Aokai Walxaha Cusub waa walxo isku dhafan oo ku salaysan maro fiber galaas ah, oo lagu dhex darey emulsion polytetrafluoroethylene (PTFE) iyo sintered. Iska caabbinta xidhashada aadka u wanaagsan ayaa muhiim u ah hubinta nolosha adeeg dheer ee xaaladaha shaqo ee firfircoon sida suumanka qaada, gaasaska la sii daayo, iyo qalajinta microwave-ka. Qodobbada asaasiga ah ee go'aaminaya caabbinta xirashada dharka heerkulka sare ee Teflon waxay ku jiraan laba tilmaame oo ka mid ah emulsion PTFE ee impregnating: qaybinta cabbirka qaybta  iyo miisaanka kelli . Labadan arrimood ayaa si toos ah u go'aaminaya daacadnimada, isku-duubnida iyo adkaanta lakabka ilaalinta dusha sare ee Teflon maro heerkul sare ah. Si kor loogu qaado habka wax soo saarka ee Teflon maro heerkul sare ah, waxaa lagama maarmaan ah in la fahmo saameyntooda muhiimka ah ee caabbinta xirashada.

Baaxadda iyo qaybinta qaybaha emulsion-ka ayaa go'aaminaya in PTFE ay si isku mid ah u geli karto oo si adag ugu dhejin karto qaabka fiber-ka galaaska ee maro heerkul sare leh oo Teflon ah.

Qiyaasta walxaha ku habboon ee dharka heerkulka sare ee Teflon : PTFE emulsions oo si gaar ah loogu talagalay Teflon maro heerkul sare ah ayaa caadi ahaan leh cabbirka walxaha celceliska ah ee lagu xakameynayo 0.15-0.35 µm (150-350 nm) . Tusaale ahaan, emulsions gaar ah oo loogu talagalay marada heerkulkeedu sarreeyo ee Teflon sida Chemours DISP 30LX waxay leeyihiin celcelis cabbir cabbirkiisu yahay 0.22µm. Qaybaha kala duwani waxay si sax ah u dhex geli karaan xidhmooyinka fiber-ka ee maro heerkul sare leh oo Teflon ah, iyaga oo samaynaya lakab difaac adag oo siman ka dib marka la jeexjeexo.

Saamaynta xun ee cabbirka qayb yar oo xad dhaaf ah : Emulsion aad u fiican ayaa leh awood xad dhaaf ah. Inta lagu jiro uurka, waxay u egtahay inay si xad dhaaf ah u gasho dhabarka ama bannaanka gudaha ee substrate-ka, hoos u dhigista qaybaha wax ku oolka ah ee u adkaysta ee lagu hayo dusha sare ee Teflon maro heerkul sare ah oo gaabinaysa nolosha xidhashada dusha sare.

Saamaynta xun ee cabbirka walxaha aadka u weyn : Emulsion aadka u qalafsan ma soo geli karo qoto dheer ee fiilooyinka fiber-ka galaaska ee marada heerkulku sareeyo ee Teflon, kaliya samaynaysa dahaar dabacsan oo dusha sare ah. Marka Teflon marada heerkulkeedu sarreeyo ay la soo gudboonaato is jiid jiid firfircoon, daahan si liidata ugu dheggan ayaa si fudud uga fuqaya qaybo waaweyn, taasoo si toos ah u horseedaysa guuldarada alaabta.

Miisaanka unugyadu wuxuu go'aamiyaa sifooyinka farsamada iyo habdhaqanka tribological ee PTFE polymer laftiisa, waxayna muhiim u tahay habka ka hortagga xirashada ee dharka heerkulka sare ee Teflon.

Xiro u adkaysta iyo habka is-saliimaynta ee Teflon maro heerkul sare ah : caabbinta xidhashada dharka heerkulka sare ee Teflon waxay ka timaadaa isku-dhafka aadka u hooseeya. Inta lagu jiro khilaaf, molecules PTFE ee dusha sare waxay u wareejiyaan shayga isku-dhafka ah, samaynta filim wareejin ah oo iskiis u duuban oo ilaaliya marada Teflon lafteeda.

Saamaynta gaarka ah ee miisaanka molecular ee waxqabadka : Daraasaduhu waxay muujinayaan in codsiyada maro heerkul sarreeya ee Teflon, PTFE-miisaanka-hoosaadku  ay inta badan soo bandhigaan iska caabbinta xirashada. Tani waa sababta oo ah miisaanka-molecular-yar ee PTFE wuxuu leeyahay silsilado molecular gaaban iyo dhaqdhaqaaq sare, awood u siinaya si deg deg ah oo xasilloon oo filim wareejin wax ku ool ah inta lagu jiro khilaafka u dhexeeya marada iyo qaybta shaqada. Taas bedelkeeda, PTFE-miisaanka-molecular-sare wuxuu u janjeeraa inuu keeno habdhaqan simbiriirixan leh inta lagu jiro isqabqabsiga, taas oo ka sii dari karta xirashada maxalliga ah ee Teflon maro heerkul sare ah.

Qaybinta cabbirka qaybtu waxay hubisaa in qoto-dheeraanta impregnation iyo adhesion lebis ee daahan on Teflon maro heerkul sare, halka miisaanka kelli uu hagaajiyo hufnaan formation of filimka wareejin is-lubricating. Kaliya iyada oo si qoto dheer loo fahmo oo si sax ah loo xakameeyo xiriirka ka dhexeeya labadan arrimood ayaa Teflon maro heerkul sare ah lagu siin karaa waxqabad heer sare ah oo ka hortag ah oo looga baahan yahay xaaladaha shaqo ee firfircoon ee muddada dheer, si weyn u kordhiya nolosheeda adeeg ee dubista cuntada, qalajinta daabacaadda, lamination photovoltaic iyo beeraha kale. Qalabka Cusub ee Aokai wuxuu diiradda saarayaa tilmaamayaashan yar yar si loo hubiyo waxqabadka macroscopic ee deggan ee Teflon marada heerkulkeedu sarreeyo.
