PAINTING METHOD USING LOW DUST AND LOW NOISE

摘要

The present invention relates to a method of painting a steel structure or a metal product using a low dust and noise chipping method. In more detail, the method of painting a steel structure or a metal product using a low dust and noise chipping method includes a wetting and drying process (S10) of spraying hot water or cold water on a paint required surface of a steel structure or a metal product at a high pressure and naturally drying the wet surface; a surface processing process (S20) for spraying blasting slurry (S) at a high pressure by using a chipping machine (100) to chip the paint required surface such that rust and foreign substances are removed; a surface drying process (S30) for spraying high pressure air on the paint required surface by using a high pressure air spray connected to a compressor (50) such that the moisture on the surface generated in the surface processing process (S20) is dried, thereby stabilizing the surface; and a painting process (S40) for coating a paint on the surface from which rust and moisture are removed through the surface drying process (S30).
