Bonding nzira ye polytetrafluoroethylene (PTFE) - sodium naphthalene solution Polytetrafluoroethylene (PTFE) - sodium naphthalene mhinduro yekurapa bonding nzira: sodium naphthalene mhinduro kurapwa kwe fluorine-ine zvinhu, kunyanya kuburikidza nekuora mhinduro uye PTFE epurasitiki kemikari reaction, kubvarura chikamu chefluorine. maatomu pamusoro pechinhu, kuitira kuti usiye carbonization layer uye mamwe mapoka epolar pamusoro.Kurapa kwemidziyo ine fluorine ine sodium naphthalene solution kunonyanya kuburikidza nemakemikari anoita pakati pekugadzirisa kupisa uye PTFE plastiki kubvarura mamwe maatomu efluorine pamusoro pezvinhu, zvichisiya carbonization layer uye mamwe mapoka epolar pamusoro.IR spectra inoratidza kuti mapoka epolar senge hydroxyl boka, carbonyl boka uye unsaturated bond anounzwa mukati, izvo zvinogona kuwedzera simba repamusoro, kuderedza kona yekubata uye kugadzirisa kunyorova.Iyi ndiyo nzira inonyanya kushanda uye inowanzoshandiswa mukutsvakurudza kwemazuva ano.Sodium naphthalene tetrahydrofuran inowanzoshandiswa senge corrosion solution.Iyo yekubatanidza maitiro ndeaya anotevera: (1) Kugadzirira kwekurapa mhinduro: imwe chiyero chesodium simbi inowedzerwa mumhinduro ye tetrahydrofuran uye naphthalene, umo chikamu chikuru chesodium metal chinodzorwa pa3% ~ 5%, uye mhinduro inokurudzirwa pakushambidzika kwekamuri kweanenge 2 h kusvikira mhinduro yacho yakasviba kana yakasviba;( 2) Nyura iyo PTFE workpiece kuti irapwe mumhinduro kweinenge 5 ~ 10 maminetsi, ibudise kunze, uye woinyudza muacetone mhinduro ye3 ~ 5 maminetsi min; ( 3) Bvisa workpiece kubva kune acetone mhinduro, sukurudza. nemvura yakachena, wozoiisa murima kuti iome zvawo;( 4) Sarudza epoxy resin, silicone kana polyurethane seanonamatira, zvakaenzana zviise pamusoro kuti isungirwe, uye pakarepo sunga.Mushure mekumira pa24 ~ 30 ℃ kwemaawa makumi maviri nemana, inogona kubatana zvakasimba.
