Classification of aluminum mirror sheet

According to different surface treatment, mirror aluminum plate can be divided into embossed mirror aluminum sheet coil, anodized mirror aluminum, color coated mirror aluminum, etc.

According to different raw materials, it can be divided into cast-rolled and hot-rolled mirror aluminum. The hot-rolled mirror aluminum sheet has better ductility and bending capacity. But the price of hot-rolled mirror aluminum sheet is slightly higher, the ductility and the bending performance is good, and the subsequent anodizing can be done. Cast-rolled mirror aluminum plate has a high-cost performance ratio. Cast-rolled mirror aluminum plate has a slightly lower price, high strength, and cannot be bent by 90 degrees.

Embossed aluminum mirror sheet/coil

Embossed aluminum mirror sheet/coil is aluminum mirror sheet with concave and convex patterns. It can increase the surface area of the aluminum plate and play a good heat dissipation effect. At the same time, the strength of the aluminum mirror sheet will also increase after embossing.

Processing technology of aluminum mirror sheet

Chalco specializes in the production of polished aluminum mirror sheet coil. The surface polishing process of aluminum plate includes three kinds mechanical polishing, electrolytic polishing and chemical polishing.

Polished aluminum mirror sheet coil usually needs chemical polishing, electrolytic polishing or mechanical polishing to make the aluminum mirror sheet surface brighter after sandblasting.

Mechanical polishing

Mechanical polishing refers to the mechanical processing process of improving the surface smoothness of metal products by means of grinding between the polishing wheel coated with polishing paste and the grinding stone of parts.

Chemical polishing

The chemical polishing equipment is simple, power-saving, efficient, and low-cost, which eliminates the cumbersome steps of hanging, and is not limited by the shape and size of the parts. Especially when mechanical polishing cannot be carried out for parts with small size and complex shape, chemical polishing can obtain uniform and bright surface.

Electrolytic polishing

Electrolytic polishing uses a DC power supply with a voltage of about 25-30V. The workpiece to be polished must be placed on the anode and have good conductivity.

Common problems of aluminum mirror sheet

Simple discrimination test of aluminum mirror sheet

The aluminum mirror sheet will not be scratched easily.

Fingerprints can't be left easily on the aluminum mirror sheet.

The mirror aluminum plate is bent without cracks.

How to polish into aluminum mirror sheet

Mechanical polishing steps in industrial field

Rough grinding, fine grinding, polishing, polishing, sandblasting, brushing or rolling, etc., different processes shall be adopted according to the roughness of the surface.

Electrochemical polishing steps in industrial field

First, the aluminum profile is mechanically polished. Then the aluminum profile is polished by chemical polishing and electrochemical polishing with phosphoric acid, nitric acid and sulfuric acid mixture.

Polishing steps in civil field

Prepare sodium nitrate aqueous solution, and then prepare a diamond grinding wheel. First, use coarse sanding paper and polishing paste to polish. Then polish it with fine polishing paste, wipe off the remaining polishing paste with glasses cloth, and clean the metal surface with clean glasses cloth.

Note that the original coarse sanding marks should be polished with coarse sanding paper and polishing paste before using fine polishing paste. In this way, manual polishing is completed, and the polished metal surface is smooth and bright.

Why choose Chalco

Chalco has mirror aluminum coils prepared by rolling technology. Mirror aluminum sheet roll is just a general term, which is classified according to the high, medium and low specular reflectance of the sheet surface. It can also be divided into 80% reflectivity mirror aluminum plate, 85% reflectivity mirror aluminum plate, 89% reflectivity mirror aluminum plate, and 95% ultra-high reflectivity mirror aluminum plate.

Chalco has more than 20 years of production experience in the mirror anodized aluminum sheet industry. The company specializes in the production of mirror anodized aluminum sheet, and is one of the only manufacturers in the world with continuous coil mirror anodizing production lines. It has the following advantages:

1. The reflectivity of Chalco hot-rolled mirror aluminum sheet is 7% - 10% higher than that of polished mirror aluminum sheet.

2. The hot-rolled mirror aluminum plate solves the problem that the traditional domestic mirror aluminum cannot be anodized. There is no wax spot on the surface, which can be directly processed for screen printing and heat transfer printing.

3. The hot-rolled mirror aluminum is produced by fully automatic equipment. Compared with the traditional semi-automatic production method of domestic mirror aluminum, the production capacity is increased by 10% and the quality consistency is 90%, thus reducing the cost by 30%.
