Description

Technical Field

[0001] This utility model relates to the technical field of exhaust dust removal equipment, specifically an exhaust dust removal device for thermal spraying. Background Technology

[0002] Thermal spraying refers to a series of processes in which fine, dispersed metallic or non-metallic coating materials, in a molten or semi-molten state, are deposited onto a prepared substrate surface to form a sprayed deposition layer. The coating material can be in powder, strip, filament, or rod form. The thermal spray gun uses fuel gas, an electric arc, or a plasma arc to provide the necessary heat, heating the thermal spray material to a plastic or molten state. Then, it is accelerated by compressed air, causing a constrained beam of particles to impact the substrate surface. The particles impacting the surface deform due to the pressure, forming stacked sheets that adhere to the prepared substrate surface. They then cool and accumulate, ultimately forming a layered coating. Depending on the coating material, this coating can achieve functions such as high-temperature corrosion resistance, wear resistance, heat insulation, and electromagnetic wave protection.
