Study on the Technology and Mechanism of Cleaning Architectural Aluminum Formwork for Concrete Pouring by High Energy and High Repetition Frequency Pulsed Laser

In the field of construction, surface architectural aluminum formwork for concrete pouring will remain adhesion layer heterogeneous composite structures. view difficulty removing layer, we studied technology and mechanism by laser cleaning in this paper. We analyzed composition distribution characteristics residual on formwork, set up a test system, carried out experiments under different storage times, cleaning. The experimental results showed that time affect quality efficiency residue pouring. For residues with short time, lasering can achieve efficient high-quality A nanosecond pulsed could strengthen hardness alloy template during cleaning, which is helpful improving durability template. main mechanisms to remove bubbles water loose structure instantly absorb high-energy make aggregate continuously air-burst. This paper provides technological theoretical support application construction.
