Study of Hydrophilic Films on Copper Tube
Copper tube was the air conditioner heat dissipation commonly used material, their hydrophilic and corrosion resistance was great significance to improve the air conditioner heat dissipation effect and the service life. Hydrophilic film was prepared with key components of silica sol and acrylic. The experiment process mainly investigated the effect of soaking time, temperature, pH value, silica sol concentration and the acrylate concentration on the hydrophilic film. Hydrophilic property and corrosion resistance were tested. The best technological conditions were as follows: at room temperature, 5min, the silica sol concentration of 60%, the acrylate concentration of 1%, pH = 13. The experimental results show that hydrophilic angle was 13°, and corrosion resistance as good as the deactivation film.
