Thaum xaiv cov zinc plating dub thiab blackening rau cov ntsia hlau nto, nws yog ib qho tseem ceeb uas yuav tau xav txog ntau yam tseem ceeb:
Txheej Thickness: Covdub zinc plating ntsia hlaufeem ntau muaj cov txheej tuab dua piv rau blackening. Qhov no yog vim muaj tshuaj lom neeg cov tshuaj tiv thaiv ntawm sodium nitrate ntawm kwv yees li 160 ° C thiab carbon atoms, uas ua rau tsim cov hlau oxide dub (Fe3O4) thaum blackening, uas ua rau cov coatings nyias.
Reactions nyob rau hauv Acid: Immersing lubntsia hlaunyob rau hauv acid tuaj yeem muab cov lus qhia txog lawv qhov kev kho mob saum npoo. Yog hais tias ib tug blackened ntsia hlau pom ib txheej dawb tom qab cov dub txheej raug tshem tawm nyob rau hauv cov kua qaub thiab txuas ntxiv mus nrog cov kua qaub, nws qhia passivated dub zinc plating. Txwv tsis pub, nws yog feem ntau blackening.
Scratch Test: Lwm txoj hauv kev kom paub qhov txawv ntawm cov kev kho mob no yog los ntawm kev siv qhov yooj yim khawb nrog ib daim ntawv dawb. Kev khawb qhov chaw dub yuav ua rau cov xim ploj mus, vim tias blackening cuam tshuam cov tshuaj tiv thaiv uas hloov qhov chaw. Ntawm qhov tod tes, cov ntsia hlau nrog zinc plating dub yuav khaws lawv cov txheej txheem raws li cov khoom siv zinc raug khi rau saum npoo los ntawm electroplating.
Peb cov screws tuaj nyob rau hauv ntau yam ntaub ntawv xws li carbon steel, stainless hlau, tooj dag, hlau alloy, thiab lwm yam. Lawv pab yog customizable kom phim koj cov kev xav tau tshwj xeeb.
