Salt spray resistance

When the coating is damaged, there is still an anti-corrosion layer to protect the substrate, which is not easy to corrode.

The enamel layer is easy to collapse and fall off after being impacted, exposing the substrate and easy to corrode.

Painting

Sandblasted

High requirements on the substrate, generally use high carbon cast iron, because the substrate is cured at high temperature

The thermal expansion and contraction are large, and the yield rate is low

Pre-treatment chrome, three coats and two bakes, more complicated

21

Construction

One coat and one bake or two coats and one bake,

Convenient construction

Three painting and two baking, complex

Three coats and one bake, the construction is more complicated

22

Installation

The board itself is lighter,

Dry hanging installation is simple and convenient

The board itself is bulky,

Transportation and installation are difficult

The board itself is lighter,

Dry hanging installation is simple and convenient

Note:

In view of the current national environmental protection policy, water-based porcelain aluminum plate has become an industry application trend. The actual effect can refer to the sample, and please refer to the appendix for related technical parameters.
