Waa maxay sababta Maro Fiber-ka Dhalada ah ay Mawduuca ka saarayso ka-hortagga Emulsion-ka PTFE? Waa maxay Mabda'a?

Sida soo saaraha xirfadlaha ah ee dharka heerkulka sare ee PTFE, Qalabka Cusub ee Aokai wuxuu ku sameeyaa daweyn heerkul sare ah maro fiber galaas ah. Ka hor inta aan la damin PTFE (Polytetrafluoroethylene) emulsion, maro fiber galaas ah ayaa la mariyaa dewaxing iyo deumming si looga saaro walxaha cabbirka (kaaliyeyaasha dunta) ee dusha fiberka. Kaaliyayaashani waxay u adeegaan xidhidhka, saliidaynta iyo ilaalinta inta lagu jiro sawirista iyo tolnimada fiber-ka. Si kastaba ha ahaatee, haddii aan la saarin, waxay si ba'an u dhimi doonaan tayada isku dhafan ee PTFE iyo fiber galaaska. Mabaadi'da inta badan waa sida soo socota:

1. Ka saar Walxaha Tamarta Dusha Hoose oo Hagaajinta Qoyaanka

Paraffin, saliidda saliidda iyo qaybaha kale ee wakiilada cabbirka ayaa ah walxaha tamarta korka hoose. Haddii la sii hayo, emulsion-ka PTFE (oo leh kacsanaan dusha hoose leh laakiin shuruudo adag) si siman uguma faafi karo dusha sare ee fiber-ka galaaska, taasoo keentay cillado sida jeexjeexyada iyo indhaha kalluunka. Iyada oo la adeegsanayo nadiifinta kulaylka sare ee kuleylka ama nadiifinta dareeraha, wasakhooyinka ayaa laga saaraa waxaana la kordhiyaa tamarta dusha sare ee fiber-ka galaaska, taas oo awood u siinaysa qoynta buuxda ee PTFE.

2. Ka Hortagga Kaarboonaynta iyo Kala-saarista Inta lagu jiro Heerkulka Sare

Heerkulka PTFE waa mid aad u sarreeya 360-380 ° C. Xabagta haraaga ah ama xabagta epoxy ee dusha sare ee fiber-ka galaaska ayaa kaarboon ka dhigi doonta heerkul aad u sarreeya, oo soo saara qaybo madow ama gaas. Tani ma aha oo kaliya inay wasakhayso dhexdhexaadiyaha (saamaynta guryaha dielectric ee laminates-ka-soo noqnoqda ee naxaasta ah) laakiin, si ka sii daran, lakabka carbonized wuxuu sameeyaa interface daciif ah, si weyn u yareynaya xoogga isku-xidhka u dhexeeya PTFE iyo fiber galaas oo keena delamination walxaha isku dhafan.

3. Samee Saamayn Xoogan 'Mechanical Anchoring'

Dexing-tayada sare leh iyo jarista (gaar ahaan daawaynta kulaylka heerkulka sare) waa wax ka badan 'nadiifinta' kaliya. Sida walxaha dabiiciga ah laga saaro, dusha sare ee fiber-ka muraayadda ayaa waxyar u dhejisan si ay u sameeyaan micropores ama soo bandhigaan kooxo badan oo silanol ah (-OH). Tani waxay abuurtaa shuruudo dahaarka xiga ee wakiilka isku xidhka (tusaale, phenyl silane), oo u oggolaanaysa PTFE inay samaysato curaarta kiimikada ama dhibcaha ku xidhidhaynta jirka oo leh fiber galaas ah iyada oo loo sii marayo wakiilada isku xidhka - u beddela 'dahaarka' fudud 'isku-xidhka' adag.

4. Ka Fogow Xumida Guryaha Dielectric Wajiga Dhexdooda

Codsiyada dhamaadka-sare sida laminates-ka-soo-celinta-sare iyo-xawaaraha sare leh ee naxaasta-xidhan, walxaha dabiiciga ah ee haraaga ah (wax, xanjo) waxay si weyn u kordhiyaan lumista dielectric hoos heerkulka sare iyo soo noqnoqda sare. Dewaxing iyo jarista waxay hubisaa in isku-dhafka fiber-PTFE-ga galaaska uu ilaalinayo lumitaanka dielectric aad u hooseeya.

Marka la soo koobo, ujeedada ugu muhiimsan ee daaweyntan waa in la baabi'iyo lakabyada is-dhexgalka daciifka ah iyo in la hubiyo in PTFE, qalab tamar hoose ah, uu gaaro qoynta qumman iyo isku-xidhka xoogga sare ee nadiifka ah, muraayadda tamarta sare leh.
