Chongqing cov txhuas profile kev lag luam raug xaiv los tsim kev lag luam txhuas tshwj xeeb, nrog kaum xyoo chaw tsim khoom thiab kev lees paub zoo. Ntau tus neeg siv nug, vim li cas qhov sib txawv ntawm xim tshwm sim tom qab electrolytic xim ntawm cov txhuas profile kev lag luam? Electrolytic xim ntawm cov txhuas profiles yog siv dav hauv tsev thiab txawv teb chaws vim nws zoo nkauj, tshwj xeeb tshaj yog hauv kev kho kom zoo nkauj ntawm cov txhuas profiles. Tam sim no, cov txheej txheem tseem ceeb yog electrolytic xim nrog tin-nickel sib xyaw ntsev, thiab cov xim ntawm cov khoom tsim tawm feem ntau yog champagne. Piv nrog rau ib qho nickel ntsev xim, cov khoom electrolytic xim nrog tin-nickel sib xyaw ntsev yog ci xim thiab puv xim. Qhov teeb meem tseem ceeb yog tias cov khoom muaj qhov sib txawv ntawm xim, thiab cov txheej txheem extrusion tsis tsim nyog thiab cov txheej txheem oxidation xim hauv kev tsim cov txhuas profiles yuav ua rau muaj qhov sib txawv ntawm xim.
