Sidee bay PTFE iyo Glass Fiber Bond u sameeyaan dammaanad la'aan aan lahayn curaarta kiimikada?

Jiangsu Aokai New Materials, oo ah hormuudka soo saaraha PTFE dhar heerkul sare leh, ayaa sharaxaya:

Polytetrafluoroethylene (PTFE) iyo fiber galaas ah (inta badan ka kooban silica) ma samayn karaan curaarta kiimikada. PTFE waxa ay leedahay tamar aad u hoosaysa oo dusha sare ah (qiyaastii 18 mN/m), oo loo yaqaan 'daahan aan dhegta lahayn', halka fiber galaas uu yahay walxo aan dabiici ahayn Labaduba waa kuwo aan isqaban karin.

At Aokai, waxaan impregnate maro fiber galaas leh emulsion PTFE, inta badan iyada oo loo marayo hababka soo socda: In kasta oo PTFE lafteedu ay adag tahay in bond, wakiilka isku xidha (sida silane) waxaa loo isticmaali karaa in lagu dhiso buundada on dusha fiber galaaska. Mabda'a ayaa ah: Dusha sare ee fiber-ka muraayadda waxaa lagu dahaadhay wakiilka isku xirka silane. Mid ka mid ah dhamaadka silane (kooxda alkoxy) waxay maraysaa falcelinta uumiga kooxaha silanol (Si-OH) ee fiber galaaska si ay u sameeyaan curaarta kiimikada; dhamaadka kale (sida kooxda amino, epoxy group) waa falcelin.

Haddii PTFE lafteeda aan la daaweynin, dhamaadka falcelinta ee wakiilka isku xidhka kama xidhi karo PTFE, markaa daaweynta dusha ayaa loo baahan yahay. Dhaqanka caadiga ah waa in lagu daro walxaha isku-xidhka ah iyo isku-xidhayaasha polymer-ka (sida PFA, FEP - resin perfluoroalkoxy ama tetrafluoroethylene-hexafluoropropylene copolymer, kuwaas oo ah fluoroplastics dhalaalaysa-processable) PTFE emulsion.

Lakabka kala-guurka : Perfluoroalkoxy resin ama tetrafluoroethylene-hexafluoropropylene copolymer waxa loo isticmaalaa lakab dhexdhexaad ah. Fluoroplastics-yadani waxay leeyihiin iswaafajin kiimikaad oo wanaagsan oo PTFE ah, waxay dhalaali karaan oo ku qulquli karaan heerkul hoose, ku xidhi kara fiber galaas silane-la daweeyay oo leh PTFE badan, waxay sameeyaan isdhexgal gradient ah, oo baabi'iya isbeddelka walaaca.

Xidhiidhka u dhexeeya PTFE iyo fiber galaas asal ahaan waa isku darka jireed ee isku-xirnaanta farsamada + cadaadiska cadaadiska + lakabka kala-guurka gradient.
