Yuav ua li cas PTFE thiab iav Fiber Bond yam tsis muaj delamination tsis muaj tshuaj Bonds?

Jiangsu Aokai Cov Khoom Tshiab, cov chaw tsim khoom ntawm PTFE cov ntaub ntawv kub kub, piav qhia:

Polytetrafluoroethylene (PTFE) thiab iav fiber ntau (tsuas yog tsim los ntawm silica) tsis tuaj yeem tsim cov tshuaj tiv thaiv. PTFE muaj qhov tsis tshua muaj zog saum npoo av (kwv yees li 18 mN / m), hu ua 'non-stick txheej', thaum iav fiber ntau yog hydrophilic polar inorganic khoom. Qhov ob yog inherently incompatible.

Ntawm Aokai, peb impregnate iav fiber ntau daim ntaub nrog PTFE emulsion, feem ntau los ntawm cov hauv qab no txoj kev: Txawm hais tias PTFE nws tus kheej yog ib qho nyuaj rau daim ntawv cog lus, ib tug coupling neeg sawv cev (xws li silane) yuav siv tau los tsim ib tug choj ntawm lub iav fiber ntau nto. Lub hauv paus ntsiab lus yog: iav fiber ntau nto yog coated nrog silane coupling tus neeg sawv cev. Ib qho kawg ntawm silane (alkoxy pab pawg) tau txais cov tshuaj tiv thaiv condensation nrog cov pab pawg silanol (Si-OH) ntawm cov iav fiber ntau los tsim cov tshuaj lom neeg; lwm qhov kawg (xws li cov amino pawg, epoxy pawg) yog reactive.

Yog tias PTFE nws tus kheej tsis kho, qhov kawg ntawm tus neeg sawv cev sib txuas tsis tuaj yeem sib txuas nrog PTFE, yog li yuav tsum tau kho qhov chaw. Ib qho kev coj ua yog ntxiv cov khoom sib txuas thiab cov khoom siv polymer (xws li PFA, FEP - perfluoroalkoxy resin los yog tetrafluoroethylene-hexafluoropropylene copolymer, uas yog yaj-processable fluoroplastics) rau hauv PTFE emulsion.

Cov txheej txheem hloov pauv : Perfluoroalkoxy resin lossis tetrafluoroethylene-hexafluoropropylene copolymer yog siv los ua txheej nruab nrab. Cov fluoroplastics no muaj cov tshuaj zoo sib xws nrog PTFE, tuaj yeem yaj thiab ntws ntawm qhov kub thiab txias, sib txuas cov silane-kho iav fiber ntau nrog cov PTFE ntau, tsim cov gradient interface, thiab tshem tawm kev ntxhov siab hloov.

Kev sib koom ua ke ntawm PTFE thiab iav fiber ntau yog qhov tseem ceeb ntawm kev sib txuas ntawm lub cev ntawm kev sib cuam tshuam + kev nyuaj siab compression + gradient hloov txheej.
