Ntau tus neeg paub tias galvanized steel yog dab tsi. Nws yog siv rau ntau yam kev siv xws li HVAC ductwork mus rau lub vaj pails; tsev kho kom zoo nkauj rau cov thoob khib nyiab. Lub spangle tiav ntawm qhov chaw ua rau nws pom kev txaus siab, tab sis kuj ua rau nws ruaj thiab corrosion resistant.
Yog li, galvanized steel li cas? Lub spangle tuaj qhov twg? Zoo, cia peb nrhiav.
Nruam Galvanizing
Nruam galvanizing siv cov zinc txheej rau saum npoo ntawm cov hlua txuas ntxiv ntawm cov hlau (coil) raws li nws dhau los ntawm zinc da dej. Lub kauj mus ncig ntawm qhov nrawm ntawm kwv yees li 600 ko taw ib feeb.Raws li lub kauj tawm ntawm zinc da dej nws nqa nrog nws ib txheej ntxiv ntawm zinc molten. Cov zinc ntxiv yog muab tshem tawm nrog cua siab (air riam) los tsim cov thickness uas xav tau. Cov khoom siv yog tom qab ntawd tso cai rau txias thiab lub spangled tiav yog tsim.Nruam galvanizing tso cai rau ntau leej tswj ntawm lub thickness thiab feem ntau yog siv rau steel khoom uas tseem tsis tau fabricated. Raws li cov txheej thickness nce, qhov kev pheej hmoo ntawm kev poob ib co txheej thaum lub sij hawm fabrication los yog forming kuj nce.
Zuag qhia tag nrho Surface Finish
Galvanized coil thiab ntawv yog tsim rau cov ntawv thov uas muaj kev tiv thaiv corrosion tseem ceeb. Lub zinc txheej lengthens lub neej ntawm cov khoom kawg, ua rau cov neeg tsim khoom tsim nyog. Qhov zoo nkauj nto tiav kuj ua rau nws ntshaw rau cov neeg siv khoom.
