Solar street lamps light pole anticorrosive process have any requirements

Solar street lamps light pole anti-corrosion design are usually using hot-rolled steel tube hot dip zinc ( Or cold galvanizing) Spray outdoor powder coating ( Or spray paint) Coating process. ( 1) Spraying outdoor powder coating has the advantages of good adhesion, high hardness, but outdoor powder coatings are resistant to

the solar street light light pole usually adopts the hot-rolled steel pipe anticorrosion design & rarr; Hot dip zinc ( Or cold galvanizing) → Spray outdoor powder coating ( Or spray paint) Coating process.

　　( 1) Spraying outdoor powder coating has the advantages of good adhesion, high hardness, but there are outdoor powder coating aging resistance is poor, shortcomings and so on loss of gloss, easy pulverization, good outdoor powder can 3 years or so, light, color difference there is less than a year of the phenomenon of color change, loss of light, the powder. Recommended excellent weather resistance of pure polyester paint, weather resistance can reach more than 7 years. Longer time requirements, recommend the paint coating.

　　( 2) Spray paint

paint variety, choose the right paint, correct construction is an important factor to ensure the quality of coating use effect.

most of the time for the use of the light pole is long-term, require high weather resistance, therefore recommend to paint fluorocarbon lacquer and acrylic polyurethane paint;

light pole substrate for galvanized steel pipe, usually as a result, solar road lights 丨 丨 solar street lamps quotation price 丨 solar street lamps, solar street lamps should choose to adapt to the special primer for galvanized steel. Do not use alkyd antirust paint, and can't use red lead antirust paint.

light pole decorative requirement is high, the film thickness cannot too thin, otherwise not enough light and full appearance, can choose epoxy micaceous iron oxide intermediate paint, epoxy paint as middle paint.

construction technology:

refer to each item of construction technology, this scheme can spray, roll besmear, brush besmear, electrostatic spraying. If need dip coating, spray coating, need to adjust the formula to fit.

drying methods: recommended 90 ℃, 30 minutes to dry; Can also be normal to dry.
