铝艺护栏的防锈处理工艺有哪些

镇江铝艺护栏在焊接成型之后,整体将会进行镀锌处理,使表面有锌层,以此达到防锈效果。镀锌分为热侵镀锌和冷镀锌、机械镀锌。

After welding, the whole aluminum barrier will be galvanized, so that the surface has a zinc layer, so as to achieve anti-rust effect. Galvanizing is divided into hot dip galvanizing, cold galvanizing, and mechanical zinc plating.

一、 热镀锌

1. Hot dip galvanizing

热镀锌是将除锈后的钢件浸入500℃左右融化的锌液中,使铝艺护栏表面附着锌层,从而起到防腐的目的。热镀锌板的生产工序主要包括:原板准备→镀前处理→热浸镀→镀后处理→成品检验等。

Hot-dip galvanizing is to immerse the rust-removing steel into the molten zinc solution at about 500 C, so that zinc layer is attached to the surface of the aluminum guardrail, so as to prevent corrosion. The production process of hot-dip galvanized sheet mainly includes preparation of original sheet, pretreatment before plating, hot-dip plating, post-plating and inspection of finished products.

二、 冷镀锌

Two. Cold galvanizing

冷镀锌也叫电镀锌,是利用电解设备将管件经过除油、酸洗、后放入成分为锌盐的溶液中,并连接电解设备的负极,在管件的对面放置锌板,连接在电解设备的正极接通电源,利用电流从正极向负极的定向移动就会在管件上沉积一层锌,铝艺护栏是先钣金加工后镀锌。

Cold galvanizing, also known as galvanizing, is the use of electrolytic equipment after oil removal, pickling, and then into the composition of zinc salt solution, and connected to the electrolytic equipment of the negative electrode, placed in the opposite of the tube zinc plate, connected to the electrolytic equipment on the positive electrode power supply, the use of electric current from the positive electrode to the negative electrode of the directional movement will sink on the tube. A layer of zinc is deposited, and the aluminum fence is first processed and galvanized.

三、 机械镀锌

Three. Mechanical zinc plating

机械镀锌在装有镀件、玻璃球、锌粉、水和促进剂的旋转滚桶内,作为冲击介质的玻璃球随着滚桶转动,与铝艺护栏表面发生摩擦和锤击产生机械物理能量,在化学促进剂的作用下,将镀涂的锌粉“冷焊”到镀件表面上,形成光滑、均匀和细致的具有一定厚度的镀层。

Mechanical zinc plating in a rotating drum with plating parts, glass balls, zinc powder, water and accelerators, as the impact medium of glass balls rotating with the drum, friction and hammering with the surface of aluminum barrier to produce mechanical and physical energy, in the role of chemical accelerators, the coating of zinc powder "cold welding" to the surface of the plating, forming Smooth, uniform and meticulous coating with a certain thickness.
