1.Sandblasting is one of the surface treatment of aluminum profile

Sandblasting is to use compressed air as the power to form a high-speed jet beam, spraying the abrasive (steel sand, brown corundum, glass beads, emery, etc.) to the surface of the workpiece to be processed at high speed.

Due to the impact and cutting action of sand, the workpiece surface has a certain degree of cleanliness and different roughness.

2.Benefits of sandblasting aluminum

The mechanical properties of the aluminum profile surface were improved after sandblasting. It improves the fatigue resistance of aluminum profile, increases the adhesion between it and the coating, prolongs the durability of the coating, and also beneficial to the flow of paint and decoration.

3. Excellent performance of products

high transparency and full measure, with special gloss and transparency, the coating has a high stereo effect, and the color of the substrate is obvious.
the high hardness, when the temperature of 180 ℃ baking 30 min, hardness can be up to 4 to 5 h.
good level of flow, strong paint film, and smooth film.
with strong binding force and penetration, the coating is all-pervasive, and the wet film and dry film have a strong binding force.
the performance is good, resistance to discoloration and corrosion when the baking temperature of 180 ℃ ~ 200 ℃ workpiece does not change color, lasting bright color products, corrosion effect is perfect.
the average of the electrophoresis is good, the paint film is evenly flat, and can reach 10-16 um in 90-200v, high efficiency, and low power consumption.
good impact resistance and artificial sweat resistance.
it can be used for the surface protection of aluminum, metal electroplating, precious metal accessories, lamps and high-end furniture.
it can be electrophoresis with various color slurry: titanium gold, general grey, real black and other colors. due to the superior screening rate of the matte electrophoresis coating, the extrusion mold pattern on the surface of the aluminum material has a certain degree of masking effect.And for the color difference of the dying process, it has a certain degree of compensation effect.
