Dab tsi yog lub hauv paus ntsiab lus ntawm txias galvanizing

(1) Kub galvanizing
Txias galvanizing, tseem hu ua electroplating, yog cov txheej txheem ntawm kev siv cov khoom siv electrolytic tshem tawm cov roj, kua qaub ntxuav, thiab tom qab ntawd muab cov yeeb nkab fittings tso rau hauv cov tshuaj uas muaj zinc ntsev. Qhov tsis zoo electrode ntawm cov khoom siv electrolytic txuas nrog, thiab zinc phaj yog muab tso rau sab nraud ntawm cov yeeb nkab fittings. Qhov zoo electrode ntawm cov khoom siv electrolytic txuas nrog lub hwj chim, thiab ib txheej ntawm zinc tso rau ntawm cov yeeb nkab fittings los ntawm kev siv cov kev taw qhia ntawm qhov tam sim no los ntawm qhov zoo electrode mus rau qhov tsis zoo electrode. Txias galvanized yeeb nkab fittings yog ua ntej thiab tom qab ntawd galvanized.
① Txoj Cai
Vim nws txoj kev tawm tsam kom hloov hauv cov huab cua qhuav, zinc yuav tsim cov xim zinc carbonate nyob rau hauv cov npoo hauv huab cua noo, uas tuaj yeem tiv thaiv sab hauv los ntawm corrosion. Thiab thaum muaj qee yam vim li cas cov txheej txheej puas thiab cov txheej txheem me me raug nthuav tawm, zinc tsim cov roj teeb micro nrog cov hlau substrate, ua rau lub fastener substrate yog cathode thiab tiv thaiv. Nws yog dav siv nyob rau hauv kev lag luam xws li tsheb thauj mus los, tab sis qhov yuav tsum tau yog ib tug trivalent chromium passivation txheej thiab zinc nickel alloy txheej los txo cov teeb meem thiab lom txheej ntawm hexavalent chromium passivation.
② Kev ua haujlwm zoo
Lub zinc txheej yog tuab, nrog zoo thiab zoo crystallization tsis muaj pores, thiab zoo corrosion kuj; Cov zinc txheej tau los ntawm electroplating yog cov ntshiab thiab corrodes maj mam hauv cov kua qaub, alkali thiab lwm yam pos huab, uas tuaj yeem tiv thaiv cov substrate ntawm fasteners. Cov txheej txheej galvanized ua dawb, xim, tub rog ntsuab, thiab lwm yam tom qab chromate passivation, uas yog qhov zoo nkauj thiab muaj kuab heev, thiab muaj qee qhov kev kho kom zoo nkauj. Vim qhov zoo ductility ntawm galvanized txheej, nws tuaj yeem tsim los ntawm ntau yam txheej txheem xws li txias stamping, dov, dabtsi yog khoov, thiab lwm yam yam tsis muaj kev puas tsuaj rau txheej.
③ Daim ntawv thov Scope
Cov teb koom nrog hauv electrogalvanizing tau dhau los ua qhov dav, thiab kev siv cov khoom siv fastener tau kis mus rau kev tsim khoom, kev tsim cov galvanized hlau mesh, electronics, precision instruments, chemical engineering, tsheb thauj mus los, aerospace, thiab lwm qhov chaw, uas yog qhov tseem ceeb heev. nyob rau hauv lub teb chaws kev khwv nyiaj txiag.
