Coil Galvalume

Coil galvalume yog cov hlau kauj uas tau kub-dip coated nrog aluminium-zinc alloy txheej. Nws feem ntau yog coated sib npaug ntawm qhov chaw ntawm cov hlau kauj siv kub -dip aluminium-zinc alloy txheej txheej txheem. Cov txheej no tuaj yeem muab cov hlau zoo dua corrosion thiab huab cua tsis kam thiab ua rau lub neej ua haujlwm ntawm cov hlau.

• Ntxuav

Piv nrog rau kev tsim cov ntawv kub kub zoo tib yam -dip galvanized los xij, kev tsim cov txhuas-zinc alloy coated steel nplooj ntawv muaj cov kev cai nruj dua ntawm kev huv ntawm lub substrate, thiab ib qho electrolytic degreasing thiab tu seem yog teem ua ntej lub qhov cub annealing.

• Annealing

Txhawm rau kom muaj qhov muaj zog txo qhov cua hauv qhov cub thiab nruj me ntsis tswj qhov xoom kub ntawm qhov cub qhov ntswg

• Kub-dip galvanizing

Txhawm rau kom tau txais cov txheej txheem zoo dua, qhov kub ntawm cov sawb nkag mus rau hauv lub lauj kaub zinc yuav tsum yog li 50℃qis dua qhov kub ntawm da dej. Kev ua kom txias sai sai yog xav tau tom qab plating, thiab qhov cua txias feem ntau yuav tsum yog 10 ~ 30℃C / s.

• Tom qab -plating kev kho mob

Alu-zinc alloy phaj feem ntau kuj tau tshaj tawm- kho nrog chromic acid passivation. Nyob rau hauv xyoo tas los no, txhawm rau txhim kho kev tsim thiab kev tiv thaiv ib puag ncig ntawm kub-dip galvanized aluminium-zinc alloy phaj, cov menyuam-coated acrylic acid txheej txheem tau maj mam hloov cov tsoos chromic acid passivation, thiab chromium-dawb organic passivation tau maj mam tau txais kev saib xyuas.

• Corrosion kuj:Galvanized steel kauj muaj zog corrosion kuj thiab kev pab cuam lub neej txog li 25 xyoo, uas yog 3-6 npaug ntawm galvanized steel kauj.
• Thaum tshav kub kub kuj:Nws muaj lub siab thermal reflectivity thiab tsim nyog ua cov khoom siv vov tsev. Nws tuaj yeem siv tau ntawm qhov kub ntawm 315 degrees Celsius.
• Recoatability:Coil alvalume tuaj yeem tuav tau zoo adhesion nrog cov xim txheej thiab tuaj yeem txau lossis hmoov-coated yam tsis muaj kev kho tshwj xeeb ua ntej-.
• Processability:Nws muaj cov txheej txheem zoo thiab tsim nyog rau stamping, txiav, vuam, thiab lwm yam haujlwm.
• conductivity:Qhov saum npoo yog tshwj xeeb kho kom tau raws li qhov yuav tsum tau ntawm electromagnetic shielding.
