Aqueous long-lasting rust preventive, engine protection combination and protection process

By combining the corrosion-inhibiting film formation and intelligent indication of water-based long-lasting rust inhibitors, the problem of the effectiveness of the rust-preventive layer in the engine cavity and the early corrosion judgment has been solved. It has achieved accurate corrosion diagnosis and full-process protection without disassembling the equipment, reduced maintenance costs and improved the environmental compatibility of rust inhibitors.
