1.How ua hluav taws xob nrog zinc piv rau cov hlau?
Qhov kev ua tau zoo ntawm Zinc me ntsis siab dua li cov hlau roj carbon tsawg (li 30% -70% siab dua), tab sis ntau dua li tus tooj liab xws li tooj liab thiab txhuas.
Lub hauv paus ntsiab lus: kev ua haujlwm ntawm cov hlau tau txiav txim siab los ntawm kev ua kom muaj zog thiab kev txav chaw ntawm cov tshuab hluav taws xob dawb. Tus naj npawb ntawm kev tsim hluav taws xob ntawm zinc (2) ze rau ntawm cov qauv hlau (2-3), tab sis cov qauv siv le
2.What yog qhov tshwj xeeb tshaj plaws ntawm zinc txheej ntawm zinc txheej ntawm conductivity?
Cov txheej nyias nyias: xws li elecoplating zinc, qhov tsis kam ntawm zinc txheej yuav raug tsis quav ntsej.
Thick coating (>50μm): xws li kub-dip galvanizing, qhov tsis kam ntawm zinc txheej yuav nce qis dua qhov kev sib tw tiv thaiv (thiab tuaj yeem tsis quav ntsej hauv cov ntawv thov kev siv.
3.Qhov dab tsi yog txheej txheej txheej txheem qauv thiab cov khoom sib txawv muaj nyob rau ntawm kev coj ua tau zoo?
Ntom ntom: ib qho kev hnav khaub ncaws thiab tuab zinc txheej tau ruaj khov sib xws; Yog tias muaj qhov hws los yog oxide txheej nyob rau hauv txheej, kev sib cuag yuav yuav nce ntxiv.
Kev kho deg: yog tias passivation yog ua tom qab galvanizing, cov yeeb yaj kiab passivation yog txheej txheej insulating yog ib txheej insulating yog ib txheej insulating, uas yuav loj tuaj yeem txo cov npoo kev ua haujlwm.
4.Yog dab tsi cov xwm txheej sib tiv tauj muaj kev coj ua?
Conduction ncaj qha: Thaum tam sim no hla dhau ntawm Galvanized Txheej, yog li kev ua haujlwm ntawm cov hlau, yog li txheej txheem kev txhim kho me ntsis (xws li galvanized xaim).
Hu rau interface interface: Yog tias qhov kev xav tau tam sim no los dhau ntawm cov txheej txheem thiab cov txheej txheem sib tham thiab lwm yam kev xav tau polish kev sib cuag thaum bolting).
5.Qhov dab tsi yog qhov kev coj ua kom zoo thiab kev ceev faj?
Process control ◦ Avoid over-passivation: Chromate passivation film thickness should be < 1μm, or use conductive passivation (such as silane treatment).
Tswj coctive porosity: kub-dip galvanizing tuaj yeem txo cov porvaning thiab txhim kho kev kho mob los ntawm kev kho kom zoo nkauj (xws li Fe-Zn Alloy Txheej).
Daim Ntawv Thov Tsim
Kev kho mob rau kev sib cuag: Grind nto ntawm galvanized txheej kom pom cov hlau zinc; Lossis siv cov tshuaj txhuam hniav (xws li cov nyiaj uas muaj cov roj silicone grease) kom txo kev sib chwv tau.
Electrochemical Compatibility: Thaum Galvanized Steel Hu rau Maskets yog qhov yuav tsum tau kom tsis txhob muaj galvanaic corrosion uas ua rau muaj kev nce siab tiv thaiv.
Txoj kev xeem
Kev Xeem Tawm Tsam: Siv cov txheej txheem plaub-kev ua mob lossis Micro-Ahmmeter ntsuas ntawm txheej, thiab xa mus rau GB / T 21388-2008 rau tus qauv.
