An Overview of Colored Aluminum Sheet Metal

  The colored aluminum sheet metal is well known for long service life, light weight, excellent surface effect and high recycling value. Different coatings are available: PE, PVDF, epoxy paint, etc. It is widely used in roofing system, building decoration and thermal insulation.

The smog is composed of various nitrogen-containing substances. The nanomaterials of Haomei colored aluminum coil use a titanium dioxide layer. The nitrogen oxide molecules are decomposed by oxygen radicals into harmless reaction products such as water and nitrates.

The PVDF-coated aluminum sheet has a good antifouling effect, and the protected object can be kept clean for a longer period of time and can be easily washed with water. It has high water repellency, and the dirt on the surface is easily removed by heavy rain.

Haomei Aluminum has two prefinished aluminum sheet production lines, using the German Siemens control system, and the core painting process with the world's advanced German roller coating technology.

The first production line adopts adopts the two-coating and two-baking hot-air curing coating process, which can accurately control the coating thickness and curing quality. In the chemical treatment process, the color aluminum plate adopts neutral treatment agent, roller coating treatment and hot air rapid drying process, which is different from the ordinary dip coating chemical treatment method, which effectively eliminates the damage to the environment.

Advanced chromium-free treatment liquid is used for surface treatment, which meets strict environmental protection requirements at home and abroad. During the curing process of color-coated aluminum plate surface coating, volatile components can be recycled and burned for secondary use.
