Tetrafluorotube sodium naphthalene mafita maganin haɗin gwiwa Hanyar

Polytetrafluoroethylene (PTFE) - sodium naphthalene mafita magani hanyar haɗin gwiwa: sodium naphthalene bayani magani na fluorine-dauke da kayan, yafi ta hanyar sinadaran dauki na lalata ruwa tare da PTFE filastik, yaga kashe wani ɓangare na fluorine atom a saman kayan, don haka yana kan saman Layer na carbonized da wasu rukunin polar an bar su a kai.

Maganin maganin sodium naphthalene na kayan da ke ɗauke da fluorine galibi ta hanyar halayen sinadarai tsakanin ruwa mai lalata da filastik PTFE don yaga wani ɓangare na atom ɗin fluorine a saman kayan, don haka barin Layer carbonized da wasu rukunin polar akan farfajiya.Bakan infrared ya nuna cewa ƙungiyoyin polar irin su hydroxyl, carbonyl da unsaturated bond ana gabatar dasu akan saman.Waɗannan ƙungiyoyi na iya ƙara ƙarfin saman ƙasa, rage kusurwar lamba, inganta jimiri, da canzawa daga wuya zuwa mai ɗanɗana zuwa mai ɗanɗano.Wannan ita ce hanya mafi inganci da amfani da ita a cikin dukkan hanyoyin da aka yi nazari a halin yanzu.Gabaɗaya, ana amfani da sodium naphthalene tetrahydrofuran azaman maganin etching.
