Epoxy-aluminum-powder-coated doors have a good anti-corrosion effect. Cement gates are thin-walled structures with a typical thickness of 12-30 mm. The concrete protection layer is very thin. Cracks, nets, stencils, shedding, and reinforcement tend to appear during operation. Or wire mesh corrosion and other diseases, and brushing epoxy aluminum powder paint gate anti-corrosion process can be a good solution to this problem. After the anti-corrosion process of the epoxy aluminum powder coating gate is applied, the gate is used for more than 10 years without flaws. According to experts from the China Epoxy Resin Industry Association, the mechanism is: the protective layer of epoxy aluminum powder paint has good alkali resistance, high impermeability, wear resistance and toughness, and the epoxy aluminum powder paint can dry and form a film on the surface of the object. , from the barrier protection. The coating formulations and formulations are epoxy aluminum powder paint epoxy resin in terms of weight ratio: dibutyl ester: xylene: ethylene diamine: aluminum powder = 1:0.15:0.15:0.08:0.15. Brushing process should be mastered. Brush the net of the gate concrete with a steel brush before use, and brush it into a light rough surface. Then wash it with a 4:1 aqueous solution of hydrochloric acid and rinse it with water for 10 minutes. Preparation of epoxy putty is also very important, first in the prepared epoxy aluminum powder paint plus appropriate amount of talc powder, modulation into a putty; then put the epoxy putty on the gate concrete surface of the pores, cracks, depressions and exposed net; After the putty is cured (generally 24 hours), it is sanded and smoothed, and the dust is brushed off to keep it clean; later, epoxy aluminum powder paint is applied. When brushing requires uniform thickness, no runny, bad bottom, thickness 0.1 mm. Each interval of 2 hours, brushing a total of 4 times.
