More and more methods to solve the surface of aluminum profiles, in addition to the general air oxidation profiles, Dongguan aluminum profiles, electrophoretic principle profiles, spray paint profiles, fluorocarbon paint profiles, wood paint profiles, etc., all kinds of color. The shortcomings of adsorption particles, the general air oxidation material does not have a great impact, but the impact of other solutions is relatively large, mainly hinder the surface of this profile beautiful and generous. In the extrusion production and manufacturing, 2030 aluminum extrusion profile adsorption particles; Through careful observation or hand rolling on the profile surface, will be found. In the sawing and basket loading process, most of the small particles can be removed by gently blowing or scrubbing with the wind. But there is also a part of the electrostatic induction is still adsorbed on the surface of the profile. After quenching and tempering, the particles adhere to the surface of the profile more closely. In the profile surface preparation processing process, because of the influence of the liquid content of the tank, some can be removed, but in the profile surface to produce small pits, some can not be cleared, then produce protrusions.
