Galvanized steel ntawv SECCCov txheej hauv qab ntawm SECC yog qhov txias txias-txias-txias steel kauj, uas dhau los ua electro-galvanized cov khoom tom qab degreasing, pickling, electroplating thiab ntau yam kev kho tom qab ntawm cov txuas ntxiv txuas ntawm electro-galvanizing cov kab ntau lawm. SECC tsis tsuas yog muaj cov yam ntxwv ntawm cov khoom siv thiab cov txheej txheem zoo sib xws ntawm cov khaub thuas txias-txias cov ntawv steel, tab sis kuj muaj kev tiv thaiv zoo dua thiab cov khoom zoo nkauj. Nws yog qhov sib tw heev thiab hloov mus rau hauv kev ua lag luam ntawm cov khoom siv hluav taws xob, khoom siv hauv tsev thiab rooj tog. Piv txwv, SECC feem ntau siv rau hauv cov khoos phis tawj.
Cov ntawv ua cov tub luam zoo nkauj SPCCSPCC yog hais txog kev nruam cov hlau ua ntu zus los ntawm kev txias txias rau hauv cov hlau lossis cov ntawv ua tuab tuab. Tsis muaj kev tiv thaiv nyob rau saum npoo ntawm SPCC, thiab nws yooj yim oxidized thaum raug rau huab cua, tshwj xeeb tshaj yog nyob rau hauv qhov chaw noo, qhov ceev ntawm oxidation yog nrawm, thiab tsaus nti xeb pom tshwm. Cov nplaim yuav tsum pleev xim, electroplated lossis lwm yam kev tiv thaiv thaum siv.Kub dip galvanized steel ntawv SGCCKub-dip galvanized steel kauj yog hais txog cov khoom tiav ib nrab tom qab kub-dov thiab pickling lossis txias-dov, uas tau ntxuav thiab annealed, thiab tom qab ntawd muab raus rau hauv molten zinc da dej ntawm qhov kub ntawm txog 460 ° C, kom tus steel ntawv yog coated nrog zinc txheej thiab tom qab ntawd quenched thiab tempered Nws yog tsim los ntawm qib thiab tshuaj kho mob. SGCC cov ntaub ntawv nyuaj dua li cov khoom siv los ntawm SECC, muaj cov dej tsis zoo (tsis txhob nqus cov qauv kos duab sib sib zog nqus), cov zinc txheej tuab dua, thiab tsis zoo hluav taws xob weldability.Hlau stainless SUS304Ib qho ntawm feem ntau siv cov hlau stainless. Vim tias nws muaj Ni (npib tsib xee), nws muaj qhov zoo dua corrosion thiab kub thaum tshav kub dua Cr (chromium) steel. Nws muaj cov yam ntxwv zoo siv tshuab zoo heev, tsis muaj cua kub kho ua kom tawv tawv, thiab tsis muaj elasticity.
Ib daim ntawv hlau qhov kev pab cuam debbrication, tiv tauj nug.
