Protective paint treatment plan: Protective paint is a hard film that can be directly bonded to the substrate, usually epoxy or polyurethane coatings. Flanges have many edges and corners, and due to the thinning effect of the edges, conventional paint systems are difficult to effectively conceal the edges. Although thickening the coating can address the issue of edge protection, it can also seal the fasteners and prevent them from being disassembled during subsequent repairs. Other than that, the coating may be damaged during bolt operation, and it is necessary to repaint from scratch after repair.
Hot melt plastic treatment solution: Hot melt plastic is essentially a wax like meltable polymer that is heated at high temperatures and sprayed onto the surface of the substrate through hot melt equipment. The advantage of this protection method is that it can be remelted and reused, saving costs. But this method still requires hot work, equipment, and construction effectiveness. Although it can be used from scratch, it is not easy to open and seal during maintenance.
Tape or semi-solid anti-corrosion tape treatment scheme: Tape wrapped in rolls (such as mineral grease tape, wax or elastic polymer wrapping tape) is wrapped around the surface of the substrate for protection. Due to the good waterproof properties of semi-solid polymers, this protection method can provide reliable anti-corrosion protection.
However, if the flange shape is messy, this information is not only time-consuming but also difficult to construct. When disassembling bolts, the data is relatively soft and easy to cut, but it is difficult to seal and restore the original protection from scratch after disassembly, so it is generally necessary to start construction from scratch. Polymer sealing bag treatment plan: The sealing bag can completely wrap the flange and is composed of low-permeability polymer, corrosion inhibitor vapor, and desiccant.
