Optimization txheej txheem rau electroplating thiab kub-dip galvanizing ntawm hluav taws xob cua sov raj
Muaj ntau yam tsis xws luag hauv cov txheej txheem kub-dip galvanizing: ① kev siv dej tsis txaus; ② Cov txheej txheem degreasing tseem siv cov tshuaj alkali sib xyaw aqueous thiab cov txheej txheem degreasing kub siab tshaj 90 degree. Qhov chaw ua haujlwm muaj cov ntxhiab tsw zoo thiab muaj hlau to thiab roughness ntawm qhov chaw ntawm lub workpiece; ③ Kev tshem tawm xeb feem ntau siv ib qho kev tivthaiv, uas tuaj yeem ua rau muaj kev xeb ntau dhau thiab hydrogen evolution ntawm qhov chaw ua haujlwm; ④ Ib feem ntawm cov khoom siv plating hnyav tuaj yeem ua rau muaj qhov tsis xws luag hauv txheej txheej thiab nce zinc noj; ⑤ Cua sov sab nraum cov hlau zinc melting lauj kaub ua rau qhov tsis zoo ntawm zinc; ⑥ Thaum lub sij hawm kub dip galvanizing, ntxiv cov ntshiab txhuas, cable txhuas hlau, npib tsib xee hmoov, hmoov av tsawg, thiab lwm yam ncaj qha rau cov kua zinc molten tuaj yeem ua rau cov kua zinc ua kom khov, muaj cov dej tsis zoo, thiab muaj cov khoom siv rau ntawm qhov chaw.
Nyob rau hauv cov txheej txheem optimization ntawm kub dip galvanizing, qhov degree ntawm kev sib txawv yog muab faib ua kua qaub pickling, acid degreasing tus neeg sawv cev yog siv es tsis txhob muaj zog alkaline tov degreasing, composite xeb tshem tawm yog siv es tsis txhob ntawm ib tug hydrochloric acid los yog sulfuric acid tov rau xeb tshem tawm, thiab kev ntxuav dej sov yog siv tom qab acid pickling los txhim kho lossis txhim kho kev tu kom zoo ntawm lub workpiece ua ntej auxiliary plating. Kev tswj xyuas nruj ntawm cov neeg ua haujlwm plating muaj txiaj ntsig zoo hauv kev txo cov zinc noj thiab txhim kho cov txheej txheem galvanized zoo.
Zinc yog ib qho tseem ceeb raw khoom rau cov hlau uas tsis yog-ferrous. Tam sim no, zinc yog thib ob tsuas yog tooj liab thiab txhuas hauv kev noj cov hlau tsis muaj hlau. Zinc hlau muaj qhov zoo dov tsis kam, hnav tsis kam, thiab corrosion kuj, thiab tuaj yeem ua rau cov alloys zoo dua lub cev thiab tshuaj lom neeg nrog ntau yam hlau. Cov khoom tseem ceeb uas tsim los ntawm thawj cov tuam txhab zinc muaj xws li: hlau zinc, zinc raws li alloys, thiab zinc oxide.
