Kushandisa epoxy simende kana adhesive yekuisa chisimbiso polymer kune girazi nesimbi uye kune pachayo.
Kuramba kwepolytetrafluorethylene (PTFE) kune chero rudzi rwekunamatira kune ngano uye kunowanzo batsira zvakanyanya sekuita kwayo kusagadzikana kwemakemikari.Asi hunhu uhwu hune imwe yakakosha dhiraivha, iyo polymer yakaoma kwazvo kubatanidza yakavimbika kune zvimwe zvinhu kana kune pachayo.Pane mhinduro yedambudziko iri yakaunzwa kumunyori nekambani inonzi Reltek.(Zvimwe pamusoro pavo pazasi).Mhinduro yedambudziko iri Sodium Naphthalide yakanyungudutswa mu 2-Methoxyethyl Ether kana muTetrahydrofuran.Izvi zvinoshandiswa semushonga kutsiva maatomu efluorine pamusoro neakawanda anoshanda uye anosungirirwa mamolecular marudzi.Mushure mekuisa iyo polymer pamusoro kunowedzera kubvuma kweakasiyana masimende, kusanganisira epoxy resin adhesives seAraldite, kana iyo inonyanya hunyanzvi Reltek Epoxy Resins.Iyo etching yakatwasuka uye inosanganisira kufumura iyo yakaomeswa uye yakasvibiswa polymer pamusoro kune mhinduro yeSodium Naphthalide kweanenge maminetsi maviri uye wobva wageza iyo yakamiswa neIsopropanol.Iyo etched surface yakagadzikana uye michina inopikisa uye inosungwa.Iyo chete yakaoma kugadzira uye kubata kweSodium Naphthalide complex.
Sodium Naphthalide inhengo ine simba rakanyanyisa yekudzikisa, uye inobata nekukasira neOxygen yemuchadenga uye nemvura.Chero kuratidzwa kwakakosha kumhepo kuchakurumidza kuimisa.Saka inogadzirwa zvakanyanya uye inoshandiswa mubhokisi regirovhosi pasi penitrogen kana kushandisa Scklenk tekinoroji.
Mukugadzirira kwakashandiswa nemunyori, 2.5 gm yeNaphthalene (GPR Rectapur) yakanyungudutswa mu25 ml yeTetrahydrofuran muSchlenk tube.Kumusanganiswa uyu 0.2 gm yesimbi ichangobva kuchekwa sodium yakawedzerwa.Iyo mhepo-nzvimbo muSchlenk chubhu yakacheneswa neArgon uye yakasimbiswa neSubaseal stopper.Tepi yepadivi yakavharwa uye schlenk chubhu yakanyudzwa zvishoma mumvura yekugezera yakachengetwa pa45C kwemaawa gumi nemaviri.
Mukushandiswa, Sodium Naphthalide inonyatso kubatwa muSchlenk chubhu kana mubhokisi regirovhosi uye kupihwa kweNitrogen kana Argon kunobatsira kudzivirira reagent oxidation panguva yekushandiswa.Hurongwa hwekunamira machubhu akaonda epolymer ekuvharira musimbi isina tsvina kana girazi tubing.
Iyo polymer chubhu yekumisikidzwa inovharirwa kumagumo kudzivirira kushuvira kweiyo etchant, uye inopinzwa nemuboora we hypodermic tsono inobaya subbaseal.Iyo Subaseal ndeyekuvharika kwakasiyana-siyana mukuti inogona kutakura akawanda machubhu emadhayamita akasiyana.Izvi zvinoreva kuti machubhu akafara chose (anosvika 6mm od) anogona kuiswa nenzira iyi.
