Kumangirira njira ya polytetrafluoroethylene (PTFE) - sodium naphthalene solution Polytetrafluoroethylene (PTFE) - sodium naphthalene solution mankhwala bonding njira: sodium naphthalene solution mankhwala a fluorine munali zipangizo, makamaka kudzera dzimbiri njira ndi PTFE pulasitiki mankhwala anachita, kung'amba mbali ya fluorine maatomu pamwamba pa zinthu, kuti achoke mu carbonization wosanjikiza ndi magulu ena polar pamwamba.Kuchiza kwa zipangizo zokhala ndi fluorine ndi njira ya sodium naphthalene makamaka kudzera muzochita pakati pa njira yowonongeka ndi pulasitiki ya PTFE kuti igwetse maatomu ena a fluorine pamwamba pa zipangizozo, motero kusiya mpweya wa carbonization ndi magulu ena a polar pamwamba.Mawonekedwe a IR akuwonetsa kuti magulu a polar monga gulu la hydroxyl, gulu la carbonyl ndi ma unsaturated bond amalowetsedwa pamwamba, zomwe zimatha kuwonjezera mphamvu zapamtunda, kuchepetsa ngodya yolumikizana ndikuwongolera kunyowa.Iyi ndi njira yothandiza kwambiri komanso yogwiritsidwa ntchito kwambiri pa kafukufuku wamakono.Sodium naphthalene tetrahydrofuran amagwiritsidwa ntchito ngati njira ya dzimbiri.Njira yolumikizirana ili motere: (1) Kukonzekera kwamankhwala: zitsulo zina za sodium zimawonjezeredwa mu yankho la tetrahydrofuran ndi naphthalene, momwe gawo lalikulu la chitsulo cha sodium limayendetsedwa pa 3% ~ 5%, ndi yankho amasonkhezera kutentha kwa pafupifupi 2 h mpaka yankho liri lakuda kapena lakuda;(2) Miwiritsani PTFE workpiece kuti athandizidwe mu yankho kwa pafupifupi 5 ~ 10 mphindi, mutulutsemo, ndiyeno muimitse mu njira ya acetone kwa mphindi 3 ~ 5; ( 3) Chotsani workpiece ku yankho la acetone, muzimutsuka. ndi madzi oyera, ndikuyiyika mumdima kuti iume mwachibadwa;(4) Sankhani epoxy resin, silikoni kapena polyurethane monga zomatira, wogawana ntchito pamwamba kuti amangirire, ndipo nthawi yomweyo chomangira.Itaima pa 24 ~ 30 ℃ kwa maola 24, imatha kulumikizana mwamphamvu.
