Bonding txoj kev ntawm polytetrafluoroethylene (PTFE) - sodium naphthalene tov Polytetrafluoroethylene (PTFE) - sodium naphthalene tov kev kho mob sib txuas txoj kev: sodium naphthalene tov kev kho mob ntawm fluorine-muaj cov ntaub ntawv, feem ntau yog los ntawm cov tshuaj corrosion thiab PTFE yas tshuaj tshuaj tiv thaiv, kua muag tawm ib feem ntawm cov fluorine. atoms nyob rau saum npoo ntawm cov khoom, thiaj li yuav tawm hauv carbonization txheej thiab ib co polar pawg nyob rau saum npoo.Kev kho cov khoom siv fluorine nrog cov tshuaj sodium naphthalene feem ntau yog los ntawm cov tshuaj tiv thaiv ntawm cov tshuaj corrosive thiab PTFE yas los rhuav tshem qee cov fluorine atoms ntawm cov ntaub ntawv, yog li tawm hauv cov txheej txheem carbonization thiab qee pawg polar nyob rau saum npoo.IR spectra qhia tias pawg polar xws li hydroxyl pab pawg, carbonyl pawg thiab unsaturated daim ntawv cog lus tau nkag mus rau hauv qhov chaw, uas tuaj yeem ua rau lub zog saum npoo, txo lub kaum sab xis thiab txhim kho qhov ntub dej.Qhov no yog txoj kev siv tau zoo tshaj plaws thiab feem ntau siv hauv kev tshawb fawb tam sim no.Sodium naphthalene tetrahydrofuran feem ntau yog siv los ua cov tshuaj tiv thaiv corrosion.Cov txheej txheem kev sib koom ua ke yog raws li hauv qab no: (1) Kev npaj cov tshuaj kho mob: ib qho nyiaj ntawm sodium hlau ntxiv rau hauv cov tshuaj tetrahydrofuran thiab naphthalene, nyob rau hauv uas pawg loj ntawm sodium hlau yog tswj ntawm 3% ~ 5%, thiab cov cov tshuaj yog nplawm ntawm chav tsev kub li 2 teev kom txog thaum cov tshuaj yog xim av los yog dub;(2) Raus lub PTFE workpiece yuav tsum tau kho nyob rau hauv cov kev daws rau li 5 ~ 10 feeb, tshem tawm, thiab ces muab tso rau hauv acetone tov rau 3 ~ 5 feeb min; (3) Tshem tawm lub workpiece los ntawm acetone tov, yaug nws. nrog dej huv, thiab tom qab ntawd muab tso rau hauv qhov tsaus ntuj kom qhuav ib txwm;(4) Xaiv cov epoxy resin, silicone lossis polyurethane ua cov nplaum, sib npaug rau ntawm qhov chaw kom sib koom, thiab daim ntawv cog lus tam sim ntawd.Tom qab sawv ntawm 24 ~ 30 ℃ rau 24 teev, nws tuaj yeem sib cog lus ruaj khov.
