Piav Xim Qhov txawv ntawm Cov Yeeb Nkab Hlau

Cov tshuaj tiv thaiv hnyav ntawm cov yeeb nkab steel feem ntau yog tshwm sim los ntawm cov tshuaj tiv thaiv muaj zog ntawm cov hlau thiab zinc, yog li cov txheej txheem ua tiav thaum chiv thawj tsim los ntawm cov hlau txheej thiab cov zinc txheej ntshiab tsuas yog txheej txheej tsis muaj zinc txheej. Grey lossis grey tsaus yog xim ntawm cov hlau-zinc alloys. Tsis tas li ntawd, yog tias qhov zoo ntawm zinc tov ua tsis zoo, cov ntsiab lus hlau hauv zinc yuav nce ntxiv. Thiab vim yog cov ntsiab lus hlau, cov zinc txheej ntshiab ntawm qhov chaw tom qab galvanizing yuav tshwm grey, ua rau cov xim sib txawv, qhov laj thawj tshwj xeeb: d Cov khoom ntawm cov khoom siv electroplated muaj ntau cov pa roj carbon, silicon, sulfur thiab phosphorus ntsiab.

Cov tshuaj tiv thaiv electrochemical ntawm hlau thiab zinc yog ntaus nqi rau inert hluav taws xob tsim los ntawm cov ntsiab lus, thiab cov txheeb ze muaj peev xwm ua rau siab, uas ua rau muaj zog ntawm cov hlau thiab zinc cov tshuaj tiv thaiv. Cov ntsiab lus ntawm cov khoom siv hlau xws li txhuas hauv zinc da dej yog qhov me me. Rau cov galvanizing ntawm active steel thiab lwm yam ntaub ntawv, cov hlau-zinc cov tshuaj tiv thaiv tsis tau zoo suppressed, thiab cov ntsiab lus hlau nyob rau hauv cov tshuaj zinc nce, uas txo qhov zoo ntawm zinc tov. Kev ntsuas kev txhim kho: xaiv qhov tsim nyog galvanizing kub raws li cov khoom siv, thiab kho cov tshuaj zinc. muaj pes tsawg leeg los tswj cov ntsiab lus ntawm txhuas thiab npib tsib xee nyob rau hauv ib tug haum ntau yam.

Txo lub sij hawm dipping kom ntau li ntau tau; txias hauv dej kom sai li sai tau tom qab tshem tawm ntawm lub lauj kaub. Purify cov zinc kua nyob rau hauv lub sij hawm los xyuas kom meej qhov zoo ntawm zinc kua thiab qhia rau peb paub koj yuav tsum tau rau kub-dip galvanized steel kav. Tus so yuav ua los ntawm peb thiab koj yuav txaus siab.
