1. Dab tsi yog qhov sib txawv hauv corrosion kuj muaj cov yam ntxwv ntawm hom sib txawv?
Ga txheej (galvanized aluminium): muaj 5% ~ 11% aluminium kuj tseem ua yeeb yaj kiab al₂o₃ oxide, nrog cov xim ntshiab al₂o₃ oxide, nrog cov xim ntshiab zinc
Zn-ni txheej (Zinc-Nickel Alloy): Thaum cov khoom siv npib tsib) tuaj yeem ncav cuag ntau dua 2000 lossis sib npaug ntawm 500) thiab muaj zog pob zeb ntau.
ZN-MG Txheej (Zinc-Magnesium Alloy): Muaj 1% Cov Ntsiab Lus (Oh) ₂ (Oj) ₂
Puas txheej (xws li zn / zn-ni cov txheej huv ob chav): cov txheej dog dig) txhim kho qhov kev ua kom huv si, thiab cov khoom ua haujlwm me me) {2}
2. Yuav ua li cas los muab corrosion tsis kam los ntawm pretreatment zoo thiab txheej txheem txheej txheem txheej txheem Optimization?
Degreasing thiab tu: Ultrasonic tu + + Txau sib xyaw ua ke kom ntseeg tau tias tsis muaj cov roj ntsha (cen))}} (anodic kev tiv thaiv), txawm tias qhov xim puas ntau, cov xim hluav taws xob tuaj yeem cuam tshuam rau kev tiv thaiv corrosion, uas yog qhov tshwj xeeb rau kev tiv thaiv Corrosion ntawm Q235 txheej txheem sib npaug.
3.} Yuav ua li cas los muab kev tiv thaiv corrosion corrosion thaum lub sij hawm molding ua khoom siv?
Lub Stamping tuag siv titanium nitride (tin) kom txo cov txheej txheem sib txhuam (cov khawb av muaj nce ntawm 85% rau 95%.
Sijhawm cov txheej tom qab tsim: stamping seem yog electrophoresed nyob rau hauv 240%) .
4.} Yuav ua li cas kom tsis txhob xeb ntawm cov qauv rhiab?
Txo cov khoob thiab dej tsub zuj zuj: tsim kev txig qhov cub thiab kua dej thiab lwm qhov chaw kom tiv thaiv dej nag los ntawm stagnating thiab ua rau muaj kev sib tsoo thiab ua rau cov pob txha creeve; Qhov sib txawv ntawm kev sib txawv ntawm DC03 Npog feem yog tswj tsis pub dhau 3 hli thiab muaj cov foob nrog kev sib tw .
Electrochemical Compatibility Tsim: Zam kev sib cuag ncaj qha ntawm Galvanized ntu sib txuas thiab tooj liab (xws li kev sib txuas ntawm cov ntsia hlau GALVANIC). Yog tias muaj kev sib cuag yog qhov tsim nyog, siv cov gaskets (xws li nylon gaskets) kom cais .
5. Dab tsi yog qhov kev txhim kho kev txhim kho systematic txhim kho?
Cov nqi ntau ntxiv (xws li sab nraud sab nrauv, cov qauv kev tiv thaiv siab + cov txheej txheem chromium-dawb kom sib npaug thiab ib puag ncig kev tiv thaiv {}}
Tus nqi-rhiab scararios (xws li cov txheej txheem tsheb lag luam hauv tsheb): tuab kub-dip galvanizing + txheej txheem ua kom zoo tshaj plaws kom ua tau zoo tus nqi kev ua haujlwm {}}
Cov Txheej Txheem Yav Tom Ntej: txhim kho rau Chromium-dawb, cov txheej txheej qis dua (xws li ZN-MG Txheej Txheem Kev Tiv Thaiv (xws li Hnav Khaub Ncaws) .
