Kub Dipped Galvanized Steel Chev
S280GD yog ib qho muaj zog, qis- alloy structural steel uas tau siv dav hauv kev tsim kho thiab tsim khoom. Nrog rau qhov tsawg kawg nkaus tawm lub zog ntawm 280 MPa, nws yog qhov nyuaj txaus rau kev xav tau cov haujlwm ua haujlwm. Qhov kub-dip zinc txheej muab kev tiv thaiv zoo tshaj plaws tiv thaiv corrosion, lav kev ua haujlwm ntev. Ua tsaug rau qhov kev sib xyaw ua ke ntawm lub zog thiab kev tiv thaiv, S280GD yog qhov zoo tshaj plaws rau cov txheej txheem thav duab, vov tsev, thiab lwm yam hnyav - daim ntawv thov.
Kub Dipped Galvanized Steel Sheet nyob rau hauv Chev (GI) yog tsim los ntawm kev dhau daim ntawv Tag Nrho Hard uas tau ua tiav cov txheej txheem ntxuav cov kua qaub thiab dov txheej txheem los ntawm lub lauj kaub zinc, yog li thov zinc zaj duab xis rau saum npoo. Nws muaj kev tiv thaiv corrosion zoo heev, pleev xim, thiab ua haujlwm tau zoo vim Zinc tus yam ntxwv. Feem ntau, kub-dipped galvanized steel ntawv thiab galvanized steel kauj txheej txheem thiab specifications yeej ib yam.
Kub-dip galvanizing yog txheej txheem ntawm kev siv cov zinc txheej tiv thaiv rau cov ntawv hlau lossis cov ntawv hlau, kom tsis txhob xeb.
* Kev tiv thaiv zoo heev -corrosion, paintability, thiab processability vim tus kheej - txi tus yam ntxwv ntawm zinc.
* Muaj los xaiv thiab tsim cov nyiaj xav tau ntawm zinc gilded thiab tshwj xeeb ua rau cov txheej zinc tuab (ntau tshaj 120g / m2).
* Muab cais raws li xoom spangle lossis ntxiv du nyob ntawm seb daim ntawv puas hla kev kho mob ntawm daim tawv nqaij.
Kev kho saum npoo
Spangle yog tsim thaum kub -dip galvanizing txheej txheem. Qhov loj, ci ntsa iab, thiab nto ntawm spangles tsuas yog nyob ntawm seb muaj pes tsawg leeg ntawm zinc txheej thiab cov txheej txheem txias. Raws li qhov loj me, nws suav nrog me me spangles, tsis tu ncua spangles, loj spangles, thiab dawb spangles. Lawv saib txawv, tab sis cov spangles yuav luag tsis cuam tshuam qhov zoo ntawm galvanized hlau. Koj tuaj yeem xaiv raws li koj nyiam thiab lub hom phiaj.
