Powder Coating Cast Iron Tub
Discussion on the technology of powder coated cast iron bathtub
Fu cast iron bathtub, want to be powder coated, the process is complicated, and it is related to the quality.
First heavy casting blank. The material of cast iron must be selected and precisely matched, and impurities must be removed to make it pure and strong. When casting the mold, the heat and flow rate must be precisely controlled to ensure that the body of the bathtub is uniform and free of bubbles and trachoma. If the body is not good, although the coating is beautiful, it will not last.
Second and surface treatment. When the body is ready, remove oil stains and rust stains. Or degrease it with lye, or remove rust with acid solution, and then clean it with water, dry it for later use. The purpose of this step is to make the surface of the green body clean and rough, which is conducive to the adhesion of the coating. If the surface is not clean, the coating is easy to peel off.
As for the powder coating, the choice of powder is crucial. The quality, color and particle size of the powder are all exquisite. Superior powder, the coating is wear-resistant, corrosion-resistant and bright in color. When coating, or by electrostatic spraying, the powder is evenly adsorbed on the green body; or by fluidized bed dipping, so that the bathtub is covered with powder. After coating, bake in the oven. Proper temperature and time can melt and cure the powder to form a dense coating. If the temperature is too high, the coating will change color and foam; if the temperature is too low, the curing will be incomplete and the performance will be poor.
Powder coated cast iron bathtub, after all these processes, becomes a good product. Its durability and beauty can add color to the house, and it shows its superiority in daily use.
