Sidee PTFE Iskuxidhitaan Teflon Dharka Heerkulka Sare ee Dharka Fiberglass-ka?
PTFE (polytetrafluoroethylene) hasan aad u hooseeya oo dusha sare ah oo loo yaqaan 'non-stick' walxo othmanufacturer–JiangsuAokaiNewMaterial TechnologyCo.,Ltd
Hababka gaarka ah ee isku xidhkaTeflon-heerkul-sare oo ay ku jiraan kuwan soo socda:
1.Mechanical interlocking (PhysicalBonding) Tani waa habka ugu muhimsan ee loo wajaho dhexda (qiyaastii 360-400 ° C), qaybaha PTFE waxay dhalaalayaan filim joogto ah, si adag u qabsanaya xirmooyin fiber ah oo aan la tirin karin.
Tani waa habka ugu muhiimsan ee loogu talagalay dhammaan tayada-sare ee PTFEfiberglassfabrics. Dusha sare ee fiberglassfabricis waxaa lagu daaweeyay asilane isku xidhka (suchasaminosilane,epoxysilane, iwm.):
Oneendofthesilane (koox siloxy), ka dib-hydrolysis, si kiimiko ah ugu xidhnaan kara kooxaha Hydroxyl-ups (-OH) dusha sare ee muraayadaha;
Dhanka kale, kooxuhu waxay leeyihiin qaab-dhismeedyo firfircoon, waxay isku gudbi karaan isku-xirnaan xoog leh oo la dagaallami kara qaybaha isku-dheelitirka ah ee fluorinated ka-hortagga dahaarka.

Si toos ah u dahaadhay PTFE natiijooyinka soodhaweynta ka dib is dhexgalka, soadedicated aprimerisisi ahaan si toos ah ayaa loogu dabaqay warshadda fiberglasssfabric. lakabkan aasaasiga ah wuxuu ka kooban yahay:
Adhesiveresins: Suchaspolyamide-imide (PAI), polyphenylenesulfide (PPS), polyethersulfone (PES), ama polytheretherketone (PEEK), kuwaas oo leh qoyaan wanaagsan iyo xoog-dhesiontoglassfibers, oo u adkeysan kara heerkulka xiga ee heerkulbeegga ah ee PTFEsinteringprocess.
PTFEmicrowder: Si loo hubiyo in ciyaartoyga ugu horreeya iyo kan ugu dambeeyaPTFE ay wada heli karaan.
Kani wuxuu ku guulaystaa isku xidhka kiimikaad iyo isku xidhka jirka ee isku-xidhka-wakiilada-la daaweeyay fiberglassfabric, samaynta lakabka beddelka.

FEP (fluorinatedthylenepropylene) ama PFA (perfluoroalkoxy) filimada , kuwaas oo leh dhibicda dhalaalaysa ee PTFE (qiyaastii 260-310 ° C) . Markay dhalaaliyaan, waxay qooyn karaan fiberglasssfabricandinter-diffous/ku dhalaali PTFEfil msurface.Habka,FEP/PFAfilimku waxay dhexdhigeen PTFEfilimka iyo warshadda fiberberglaska,kuleylka iyo cadaadiska,iyo qaboojinta ka dib,oo aan qaabaysanayn.
5.Qaab-dhismeedka Gradient iyada oo loo marayo is-maris badan iyo wareegyo isku xidhid
Heerkul badan oo heerkul sare leh ayaa soo saara geeddi-socod-is-uur-qaadis badan oo badan: dhalmada ugu horreysa waxay isticmaashaa PTFE kala-baxyo ay ku jiraan xirmooyinka iyo isku-xirnaanta, taas oo u oggolaanaysa in-primertopenetratedeepintofiberbundles. Isku soo wada duuboo, dib-u-dhacyo badan oo isdaba joog ah oo leh PTFEemulsionn iyo guulo la taaban karo ayaa la qaaday, taasoo keentay inay kordheyso nadiifnimada sare ee PTFE ee dusha sare. Tani waxay abuurtaa qaab-dhismeed si tartiib-tartiib ah u beddelka lakabka fiberglass-fabric ilaa PTFE, oo leh cadaadis hoose iyo xoog isku-xidhid xooggan.
