Yuav muaj duab galvanized galvanized yog welded?
Galvanized cov plaub hau yuav welded, tab sis vim lawv yog coated txheej (kub} Kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov cuam tshuam ntawm cov txheej txheem zinc txheej, thiab {{{{{} Lub ntev corrosion tsis kam ntawm cov qauv.
I. Qhov teeb meem tseem ceeb ntawm Galvanized lub raj raj Vuam Vuam Vuam: Qhov cuam tshuam ntawm cov txheej zinc
Lub suab nrov ntawm zinc (kwv yees li 419 degree) yog qhov qis dua li ntawm cov hlau (kwv yees li 1538 degree). Kev kub siab thaum lub sij hawm vuam yuav ua rau cov txheej zinc me ntsis kom yaj, muaj peev xwm ua rau cov teeb meem hauv qab no, uas yuav tsum zam ua ntej:
Cov tshuaj lom fumes: zinc oxide fumes (feem ntau hu ua "zinc evaporation tuaj yeem ua rau" hlau fever, thiab lwm yam) yog nqus tau lub sijhawm ntev. Yog li ntawd, qhov chaw dim kom tsim nyog thiab kev tiv thaiv tus kheej (xws li hnav cov pa tawm) yog qhov tseem ceeb.
Cov Kev Cuam Tshuam Ntawm Weld Zoo:
Zinc Vinc Vacor tuaj yeem yooj yim tsim cov hws hauv Weld, txo Weld ntom ntom ntom ntom.
Molten Zinc tuaj yeem nkag mus rau hauv Weld, ua rau Zinc embrittlement (txo weld kev nruj thiab nquag mus tawg). Qhov kev pheej hmoo no yog qhov tshwj xeeb tshaj yog qhov kub tsawg lossis ntxhov siab.
Kev rhuav tshem cov kev tiv thaiv corrosion: lub siab vuam qhov kub thiab txias tuaj yeem hlawv tam sim no lub zinc txheej ncig ntawm weld thiab thaj tsam ib puag ncig (kwv yees li 50-100mm), tawm ntawm cov thawv tsis muaj kev tiv thaiv. Yog tsis muaj kev tiv thaiv corrosion ntxiv, xeb tau yooj yim los ntawm Weld.
