Latest Patents
Hirai's latest patents include a method for forming a rustproof film on PC strands and a double rustproof PC strand. The method for forming a rustproof film involves setting the thickness of the resin film to 200±80 μm. Pre-heating is performed within a temperature range of 60 to 150°C to prevent cob-webbing during the melting of the synthetic resin powder coating material. Post-heating is conducted within a range of 150 to 250°C to ensure uniform thickness on the outer surfaces of the core wire and surrounding wires. The synthetic resin powder coating material used contains particles with diameters ranging from 0.1 to 250 μm, and the line speed is set between 5 to 10 m/min. The double rustproof PC strand boasts superior durability and semi-permanent rustproof performance, achieved through a combination of wire drawing and plating treatments.
