Q: Cov nyhuv ntawm Galvanized Steel nto ntawm Corrosion Kuj?
A: Moderate roughness: tsim nyog nto nto tuaj yeem nce cov khoom siv tshuab ua ke ntawm cov khoom siv hluav taws xob (xws li cov tshuaj noo thiab qeeb qeeb) rau hauv substrate .
Kev Ntxim Siab Tshaj Plaws: "Corrosion Taps" tau yooj yim tsim nyob rau hauv cov valasy lossis lwm qhov kev tsis txaus siab los ntxuav, xws li pitting) .
The coating thickness on the rough surface is uneven (the coating is thin in the concave area and thick in the convex area). The thin coating area is easily corroded and penetrated first, causing the substrate to rust.
Kev ntxhib yog tsawg dhau: ib qho chaw saum npoo uas yog dhau lawm yuav txo cov neeg sib txuas ntawm txheej thiab cov txheej txheej yooj yim rau tev thiab poob nws cov nyhuv tiv thaiv {}}
Q: Cov nyhuv ntawm qhov saum npoo roughness ntawm Galvanized steel ntawm cov khoom siv neeg kho tshuab?
A: Cov siab heev roughness: lub ntsej muag saum npoo av tau dhau los ua kom muaj kev ntxhov siab thaum kev sib txhuam, ua rau cov kab sib txuas thiab cov iav ntsuas kev sib txuas).
Tsawg dhau roughness: dhau du ib qho yuav txo qhov kev sib txhuam cov coefficients ntawm cov khoom (xws li stair treads thiab anti-npleem cov hlau daim hlau) {}
Q: Qhov twg galvanized steel nto deg roughness muaj rau txheej thiab xim nplaum?
A: Tsim nyog roughness tuaj yeem tsim ib qho "thauj mus rau cov qauv"
Tsawg heev roughness (xws li daim iav polished saum npoo) yuav ua rau tsis txaus ntawm txheej, yooj yim rau npuas thiab poob tawm; kev ntxhib siab dhau yuav ua rau txheej txheej tsis sib xws thiab cov npoo av tsis zoo .
Q: Dab tsi ua rau cov npoo roughness ntawm galvanized steel muaj nyob rau ntawm cov tsos zoo?
A: Cov xwm txheej ua kom zoo nkauj, thiab lwm yam {}}}}}}} Cov khoom siv ncab ntau dhau, cuam tshuam rau cov tsos.
Q: Qhov twg cuam tshuam ua qhov saum npoo roughness muaj nyob rau tom ntej ua zoo?
A: Rau galvanized seem uas xav tau tom ntej ua xws li vuam, electroplating, thiab txau, kev sib txau saum npoo yuav cuam tshuam rau kev ua zoo .
Piv txwv li: thaum vuam, roj lossis oxides kuj tseem nyob hauv qhov chaw tsis xws luag xws li Weld pores thiab tawg.
Thaum lub sij hawm electrolating, cov txheej ntawm cov ntxhib saum npoo yog qhov tsis sib xws, cuam tshuam rau cov tsos thiab kev tiv thaiv kev ua haujlwm .
