Steel-lined tetrafluorotube sodium naphthalene kua kho kev sib txuas txoj kev

Polytetrafluoroethylene (PTFE)-sodium naphthalene tov kev kho mob txoj kev sib txuas: sodium naphthalene kev kho cov khoom siv fluorine, feem ntau yog los ntawm cov tshuaj tiv thaiv ntawm cov kua corrosive nrog PTFE yas, rhuav tshem ib feem ntawm cov fluorine atoms ntawm cov khoom siv, yog li ntawd nws yog nyob rau saum npoo Ib txheej carbonized thiab ib co polar pawg tau tso rau ntawm nws.

Cov tshuaj sodium naphthalene kev kho mob ntawm cov ntaub ntawv uas muaj fluorine feem ntau yog los ntawm cov tshuaj tiv thaiv ntawm cov kua corrosive thiab PTFE yas los rhuav tshem ib feem ntawm cov fluorine atoms ntawm cov khoom siv, yog li tawm hauv ib txheej carbonized thiab qee pawg polar nyob rau hauv. nto.Lub infrared spectrum qhia tau hais tias pawg polar xws li hydroxyl, carbonyl thiab unsaturated bonds tau nkag rau ntawm qhov chaw.Cov pab pawg no tuaj yeem ua kom lub zog saum npoo av, txo qhov kev sib cuag ntawm lub kaum sab xis, txhim kho lub wettability, thiab hloov los ntawm qhov nyuaj rau nplaum rau nplaum.Qhov no yog txoj kev siv tau zoo tshaj plaws thiab feem ntau siv ntawm txhua txoj kev kawm tam sim no.Feem ntau, sodium naphthalene tetrahydrofuran yog siv los ua cov tshuaj etching.
