Wọpọ aluminiomu alloy dada itọju lakọkọ -Apá Ọkan

Different surface treatments can be applied to aluminium profile, and each treatment process has its own unique advantages, disadvantages and application scenarios.

First, mechanical surface treatment technologies. Sandblasting: Its core principle is that high-speed abrasive particles impact and compress the surface of aluminum extrusions to create plastic deformation, forming a layer of residual compressive stress.Sandblasting can cover minor scratches and blemishes on the aluminum extrusion surface to a certain extent.
