1. Lungisa iiparamitha zenkqubo ye-electroplating
Lawula ngokungqongqo ixabiso le-pH lomqulu omkhuluucingo lwezinkibath, uphando lubonisa ukuba ubukhulu ibhafu pH ixabiso kuchaphazela ngqo umgangatho wentsimbi yokwambathisa ucingo, ulawulo olungafanelekanga ixabiso pH kuya kubangela ukutyabeka ekhululekile.Xa ixabiso le-pH lingaphezulu kwe-3, i-coating yensimbi yensimbi ine-burr ebangelwa yi-dendrites emihle, kwaye umphezulu awugudi.Ukuxinana kwangoku kulawulwa ngokungqongqo.Ukususela kwi-microscopic morphology, ukuphakama koxinano lwangoku, ubukhulu be-zinc layer grain deposition, iyancipha i-zinc layer ehambelanayo.
Ngokuchasene noko, i-denser i-ion deposition, ingcono umgangatho we-zinc layer.Ngaphantsi kwemeko yokuba i-zinc layer i-zinc layer kwaye ikhanya, umgangatho we-zinc layer kwindawo nganye yeyunithi kufuneka ufikelele kwi-80g / m2, kwaye iiparameters zenkqubo kufuneka ziphuculwe ngolu hlobo lulandelayo: ubuninzi bangoku yi-16-20A / dm2, ukuxinwa kwe-zinc isisombululo se-sulfate yi-500g / L, kunye nexabiso le-pH yi-2.5-3.0.
2. Lungisa iiparamitha zenkqubo yokudweba kwitanki yamanzi
Ngokuhambelana ngokungqongqo kunye ne-multi-pass encinci yokulinganisa izinga lokunciphisa, izinga lokunyanzeliswa lilonke liyi-96.48%, ukunciphisa ukukrazula kwe-zinc layer.Umzobo wonke womzobo wenziwa nge-tungsten steel die kunye ne-polycrystalline die.I-Angle yekhowuni yokusebenza yomzobo wocingo wokufa yi-12 ° ~ 16 °, kwaye ubude bebhanti yokulinganisa yi-0.15 ye-diameter yocingo, ukwenzela ukuba kuqinisekiswe ukuba ukuguqulwa komgca we-zinc ngokusisiseko kuyahambelana. i-steel wire substrate.
Inkqubo yokujikeleza okupholisa isebenzisa ukutshiza ukupholisa umzobo wokufa, kwaye ithatha ubushushu obuninzi obuveliswa ngumatshini wokuzoba kwisantya esiphezulu sokuzoba ngexesha lokuqinisekisa umgangatho wocingo.Lawula iiparamitha zenkqubo yokudweba: isantya sokudweba 10 ~ 12m / s;Uxinzelelo lomoya 8 ~ 10N;Ukulinganisa ubude 30km;Iqhezu lobunzima be-lubricant yi-3.5 ~ 4.5%;ixabiso le-pH ye-lubricant 7 ~ 8;Ubushushu beLubricant 30 ~ 40℃.
Emva kokulungiswa kwenkqubo, ukuveliswa kobuninzi be-0.80mm electroucingo lwentsimbii-electro galvanized zinc layer quality ilawulwa ngaphakathi kwe-80 ~ 90g / m2, i-zinc layer quality dispersion incinci kakhulu;Iziphumo zibonisa ukuba ubunzima obuqhelekileyo be-zinc layer yi-14.5g / m2, ukulahlekelwa kwe-zinc layer ingaphantsi kwe-5%, kwaye amandla ombane we-wire wire yi-2300 ~ 2500MPa.Ayilawulanga ngokufanelekileyo kuphela umgangatho we-zinc layer yocingo lwentsimbi ekrwada, kodwa ikwanciphisa inkunkuma engeyomfuneko kunye neendleko zokuvelisa.
