How to protect the large factory steel structure？

Spraying zinc or aluminum spraying on large factory steel components can effectively anticherably. Zinc, aluminum is negative potential and steel structure constitutes a sacrifice anode maintenance effect, so that steel is basically protected. At present, aluminum coating is used to prevent the corrosion of industrial gas and marine air. The characteristics of large factory steel structures are sprayed and sprayed zinc. The characteristics are as follows.

1. The combination of aluminum coating with the factory steel structure is firm and the coating life is long, and the long -term economic benefits are good.

2. Flexible craftsmanship, suitable for the long -term protection of important large -scale and difficult maintenance steel structures, can be constructed on -site.

3. The closure of zinc spraying or aluminum coating with anticorrosive coatings can greatly extend the number of life of coating. From the perspective of theoretical and practical effects. The coating of zinc spray or aluminum is the best bottom layer of anticorrosive coatings. The protection life of the composite coating of metal spray coating and anticorrosive coatings is longer than that of metal coating and anti -corrosion coating protective layer. Long -acting coatings of heavy corruption consisting of primer, intermediate paint, and facial paint.

From long -term economic thinking, the factory steel structure is the most economical. However, one -time investment is large, and good coating can not be repaired within 10 years. The intermediate paint and acrylic polyurethane long -acting protection system of epoxy zinc -enrichment of epoxy are more economical.

The steel structure of the factory is commonly used in zinc or aluminum. Extract corrosive coatings to form a long -effect anti -corrosion structure. Or use supporting heavy anticorrosive coatings to paint for protection. Metal zinc and aluminum have great characteristics of atmospheric corrosion.
