钢结构喷铝喷锌防腐的原理

发布时间:2015-9-6 9:02:00 浏览次数:701



钢结构喷铝喷锌防腐技术中尤以电弧喷涂应用最为普遍,其应用前景也更为广泛。电弧喷涂防腐原理是利用电弧喷涂设备,对两根带电的金属丝(如锌、铝等)进行加热、熔融、雾化、喷涂形成防腐涂层,外加有机封闭涂层的长效防腐复合涂层该涂层的显著特点是:

具有较长久的耐腐蚀寿命其防腐寿命可达到50年以上同时该防腐涂层在30年使用期内无须其它任何防腐维护;30年以后的维护,仅须在电弧喷涂层上刷封闭涂料;无须重新喷涂,实现一次防腐,涂层经久有效。
电弧喷涂层与金属基体具有优良的涂层结合力(可达10Mp以上),金属喷涂层以机械镶嵌和微冶金与基体金属相结合,在轻微的弯曲、冲击或碰撞下也能确保防腐涂层不脱落、不起皮、结合牢固、防腐长久有效,这一点是其它任何表面防腐涂层无法达到的。

钢结构喷铝喷锌防腐涂层原理为阴极保护,在腐蚀环境下,即使防腐涂层局部破损,仍具有牺牲自己保护钢铁基体之效果。涂层(阳极)与钢铁基体(阴极)的面积比≥1;而富锌涂料的阳极与阴极比都<1,其保护效果和结合力也远远低于电弧喷涂防腐涂层。


Especially in steel structure spray aluminum zinc anticorrosion technology, arc spraying applied in the most common, its application prospect is also more widely. Arc spraying anti-corrosion principle is the use of electric arc spraying equipment, the two electrically charged metal wire (such as zinc, aluminium, etc.) for heating, melting, atomization and spray forming anticorrosive coating, and long-term anti-corrosion composite coating of organic coating, closed the significant characteristic of the coating is:

Have a long use life its anti-corrosion life can reach more than 50 years and the anticorrosion coating used in 30 years period without any other anti-corrosion maintenance; After 30 years of maintenance, only on the arc spray coating to brush an enclosed coating; Need repainting, realize a preservative, effective coating over a long period of time.

Arc spraying coating and metal substrate with excellent adhesion (can reach more than 10 mp), metal coating layer with mechanical setting and micro metallurgy combined with matrix metal, under slight bending, impact or collision can also ensure that the anti-corrosion coating fall off, peeling, combined with strong, anti-corrosion is effective for a long time, it is out of reach for any other surface anticorrosion coating.

Principle of steel structure of aluminum zinc spraying anti-corrosion coating for cathodic protection, in corrosive environment, even if the anti-corrosion coating and local breakage, still have sacrificed themselves to protect the effect of the steel substrate. Coating (anode) and the area ratio of the steel substrate (cathode) is 1 or more; And zinc rich coating of anode and cathode than < 1, the protection effect and the binding force is far less than the arc spraying anti-corrosion coating.
