Construction
High-pressure water jet surface treatment
Surface treatment with ultra-high pressure water jet technology can be completely dust-free, spark-free, and flash-explosion-free, resulting in a clean surface with no salt residue. Solvent-free, moisture-resistant epoxy coatings can be directly applied to surfaces that are damp and prone to flash rust after high-pressure water treatment. This coating has no solvent volatilization, no safety hazards, and has excellent anti-corrosion properties, achieving a perfect combination of safety, environmental protection, and long-term anti-corrosion effects.
4 core advantages
High-pressure water spraying provides the best surface with almost no salt for coating, and provides a longer foundation for the subsequent coating life;
High-pressure water spraying is more thorough in treating complex steel structure surfaces with many corner welds and bolt joints in pipe corridors:
High-pressure water spraying does not produce dust, and on-site construction is more environmentally friendly;
High-pressure water spraying does not produce sparks, has no flash explosion hazards, and is safer.
