Introduction
The commonly used anti-corrosion and anti-rust primer for steel structure corrosion prevention is an epoxy zn-rich primer with cathodic protection effect. The paint not only has strong attachment ability for the surface of sandblasted steel, but also has strong corrosion resistance and high cost performance. With the increase of people's love, it is widely used in all kinds of steel structure anti-corrosion engineering.
As a two-component anti-rust primer, epoxy zinc-rich primer has excellent anti-rust properties, adhesion, mechanical properties and supporting properties. It is suitable for steel anti-rust in atmospheric environment, and is widely used in general anti-corrosion, chemical atmosphere, Marine environment and other anti-corrosion and weatherproof coating, such as: Plant steel structure, large Bridges, port machinery, heavy machinery, oil mining and mine equipment, buried pipelines, oil storage tank outer wall, gas tank outer wall and ship hull and deck above the water line and other steel structure heavy anti-corrosion system.
epoxy zinc-rich primer
When zinc-rich paint is applied to steel structure bridge primer, storage tank exterior anticorrosive primer, container exterior anticorrosive paint, steel structure anticorrosive paint, ship shell primer, port facility anticorrosive corrosion prevention and other atmospheric environment, it is necessary to choose a reasonable supporting system, and adopt the matching structure of prime-intermediate paint-top paint to achieve the purpose of long-term protection of the substrate. Generally, the coating system of epoxy zinc-rich primer + epoxy iron intermediate paint + acrylic polyurethane topcoat is more extensive.
In the actual use process, the proportion of paint and curing agent should be in accordance with the requirements of the manufacturer, and the special diluent used, the commonly used brushing method is gas spraying, airless spraying, brush coating, etc., according to the shape of the steel structure, area and other reasonable selection, the thickness of the paint film brushing should be controlled at 70-80μm to achieve better anti-corrosion effect.
In the above article, we introduce the widely used coating system. When carrying out the work of this coating system, we should ensure that after the completion of the primer coating, the intermediate paint is painted after an interval of 24 hours. The intermediate paint not only has excellent adhesion, anti-corrosion, shielding and thick coating, but also improves the overall thickness of the paint film and enhances the anti-corrosion effect. The film thickness can be sprayed to 100-150μm to achieve the specified film thickness.
After the intermediate paint is finished, the acrylic polyurethane topcoat is applied at an interval of 24 hours. The topcoat is a high-performance anticorrosive paint with high weather resistance, acid and alkali resistance, strong film and good decoration. Through the protection of the top paint layer, the bottom epoxy coating is avoided by ultraviolet radiation and powder, and provides strong protection and decoration.
