Kub-dip galvanizing yog txheej txheem uas cov hlau molten reacts nrog cov hlau substrate los tsim cov zinc-hlau alloy txheej, tsim kom muaj kev sib raug zoo ntawm cov hlau hauv paus thiab txheej.
Hauv kev ua ntawmSPA-C weathering steel daim hlau, thawj kauj ruam yog acid pickling, uas tshem tawm cov hlau oxide nplai thiab nto impurities los ntawm steel nto.
Tom qab pickling, SPA-C weathering steel phaj yog kho nrog aqueous tov ntawm ammonium chloride, zinc chloride, los yog ib tug tov ntawm ammonium chloride thiab zinc chloride. Lub phaj yog tom qab ntawd yaug hauv lub tank ntxuav thiab tom qab ntawd muab tso rau hauv qhov kub kub -dip galvanizing da dej.
Thaum lub sij hawm kub -dip galvanizing, ib tug complex ntawm lub cev thiab tshuaj cov tshuaj tiv thaiv tshwm sim ntawm SPA-C weathering steel substrate thiab cov zinc molten.
Cov tshuaj tiv thaiv no tsim cov zinc-hlau alloy txheej txheej uas muab kev tiv thaiv corrosion zoo heev thiab kev ua haujlwm ntev.
Lub zinc-hlau alloy txheej yog sib koom ua ke nrog cov txheej txheej ntshiab zinc txheej thiab SPA-C weathering steel matrix. Yog li ntawd, kub-dip galvanized SPA-C weathering steel daim hlau qhia qhov zoo ntawm cov txheej txheej, muaj zog adhesion, thiab ntev kev pab cuam lub neej, ua rau lawv haum rau ntev - siv nyob rau hauv xav tau sab nraum zoov thiab corrosive ib puag ncig.
09CrCuSb steel yog dab tsi?
09CrCuSb, tseem hu ua ND steel, yog ib qho qis - alloy corrosion- cov hlau tsis muaj zog tshwj xeeb uas tsim los siv rau hauv cov kua qaub dew point corrosion ib puag ncig. Nws muaj cov ntsiab lus alloying xws li chromium (Cr), tooj liab (Cu), thiab antimony (Sb), uas ua rau nws muaj zog tiv thaiv sulfuric acid thiab flue gas corrosion.
Vim li cas 09CrCuSb hu ua ND steel?
"ND" sawv rauNitric acid thiab Dew -point corrosion kuj. Cov hlau tau tsim los tiv thaiv qis -kub acid condensation corrosion feem ntau pom nyob rau hauv boilers, heat exchangers, thiab flue gas systems.
Puas yog 09CrCuSb steel muaj qhov zoo weldability?
Yog lawm. 09CrCuSb steel muaj qhov zoo weldability. Cov txheej txheem vuam txheej txheem xws li SMAW, SAW, thiab TIG tuaj yeem siv tau, tab sis qis -hydrogen electrodes thiab preheating kom zoo yuav raug pom zoo rau cov ntu tuab.
Puas yog 09CrCuSb haum rau siab -kev pabcuam kub?
09CrCuSb yog tsim los rau nruab nrab - qhov kub thiab txias qhov chaw uas acid dew point corrosion tshwm sim. Nws tsis yog npaj rau siab heev - qhov kub siab ntawm lub nkoj siv yam tsis muaj kev ntsuam xyuas zoo.
