Whether the amusement facilities are indoors or outdoors, anti-corrosion coating is necessary. The corrosion of steel has brought huge economic losses to amusement equipment (facilities) and caused great difficulties in the operation of amusement equipment (facilities). Steel is corroding all the time under natural conditions (atmosphere, natural gas, soil) or artificial conditions (acids, alkalis, salts and other media). The fundamental reason is that steel is in a thermodynamically unstable state. Under the above conditions, they will restore their original relatively stable state, generate iron oxides, carbonates, etc., or transform into soluble ions. This process is the corrosion process of metals. Therefore, it is necessary to do a good job in the anti-corrosion coating of the metal of amusement equipment (facilities).
Requirements and implementation of anti-corrosion coating
1. Before construction, the surface to be coated should be rust-free. The quality of the surface rust removal treatment should reach the Sa2.5-Sa3.0 level specified in GB/T8923 “Surface rust grade and rust removal grade of steel before coating”.
2. During construction, the ambient temperature should be between -5℃ and 35℃ (epoxy paint and water-based paint should be between 10℃ and 35℃). Before construction, pay attention to changes in weather and temperature. Anti-corrosion coating construction should be stopped in rain, fog, snow or when the relative humidity is greater than 80%.
3. The “chemically reactive” two-component coating in the product must be weighed and mixed according to the specified ratio when used, and can only be applied after ripening for the specified time. The ripened coating should be used up within the specified applicable period to avoid cementation and waste.
4. During construction, it is generally not necessary to add diluent. If the paint (paint) is too thick, a small amount of diluent can be added. The amount should generally be controlled at 5~10% of the weight of the paint (paint). Adding more should avoid affecting the quality of the coating (paint) layer (except for special varieties).
5. Paints (varnishes) that are dangerous goods should be stored in a cool and ventilated place, away from fire and heat sources. Open flames are strictly prohibited at the construction site. There should be good ventilation conditions and safety measures should be practical and reliable to prevent poisoning and fire accidents.
