400A；0.4 MPa of air pressure~0.6MPa, compressed air quality：It is greater than or equal to 0.1 in the every cubic metres of air of dedusting precision
The particle of μm size is no more than 10, oil-containing water≤0.1mg/m3；Gun slot distance steel structured metal surface is maintained at 180
Mm~200mm, gun slot central axis is as far as possible perpendicular to being sprayed-on steel construction metal surface, gun slot central axis and workpiece table
Face allows slanted angle >=45 °, and spray gun laterally at the uniform velocity moves during spraying.
Steel construction metal surface cannot be when 4 is small during interior completion coating aluminum, segmentation spraying, and segmentation principle is：
Blasting treatment and non-grit blasted surfaces edge should reserve 100mm~150mm, and grit blasted surfaces without aluminium-plated, make next
It is easy to continue during Duan Jinhang blasting treatments.Carry out next section of sandblasting or it is aluminium-plated when, should and lacquered surface aluminium-plated to leading portion wrap
Prick/block protection.
After the aluminium film of steel construction metal surface spray metal, aluminium film is closed using reactive coating application within 4 hours
Hole.
Steel construction metalwork using segmentation cannot be sprayed when 4 is small during interior completion application closing aluminium film, be segmented principle
It is：Should be reserved at aluminium-plated and not aluminium-plated edge 80mm~120mm aluminium-plated surface without Seal treatment, make next section into
Row is easy to continue when aluminium-plated.
