Q:What are the characteristics of brush-coated anti-corrosion performance?
A:Advantages: simple tools, flexible operation, suitable for complex structures or small area construction.
Disadvantages: low efficiency, uneven coating thickness, easy to produce brush marks and bubbles, poor density of anti-corrosion layer.
Q:What are the advantages and disadvantages of roller coating?
A:Advantages: Construction efficiency is higher than brushing, suitable for flat or regular surfaces, and the coating thickness is relatively uniform.
Disadvantages: It is difficult to penetrate into complex structures, and the roller is prone to residual air, causing bubbles, and the integrity of the anti-corrosion layer is limited.
Q:What are the advantages and disadvantages of air spray?
A:Advantages: thin and uniform coating, smooth surface, high coverage efficiency, and can achieve uniform coating of complex structures.
Disadvantages: low coating utilization (part of the coating is atomized and lost), high construction environment requirements (ventilation and explosion-proof are required), coating thickness is greatly affected by air pressure and nozzle, and the anti-corrosion performance is insufficient when it is too thin.
Q:What are the advantages and disadvantages of airless spraying?
A:Advantages: Suitable for batches of small parts or porous components, the coating evenly covers depressions and gaps.
Disadvantages: The solvent evaporates quickly, the coating thickness is difficult to control (too thick and easy to sag), the solvent residue may affect the adhesion, and it is not suitable for large components.
Q:What are the advantages and disadvantages of spray coating?
A:Advantages: high degree of automation, high efficiency, uniform coating, suitable for assembly line production.
Disadvantages: large coating consumption, complex structures are prone to coating dead corners, and edges may accumulate or sag.
