1, acid (base oil used in more): using metal rust remover for cleaning oil steel structure surface, and then rinse with water, and with the scrub brush, which can remove more oil. Treatment method of glass fiber reinforced plastic prior to substrate
Methods: 2, mechanical grinding machine with clear surface oxide skin, rust steel structure membrane residual sand, welding slag, dust, oil and other substances, to make the coating firmly attached on the surface of the workpiece, it must be cleaned prior to coating on the surface of the workpiece, otherwise, not only affects the binding force of the coating with the base metal and corrosion resistance, but also to the base metal in even with protective coatings are able to corrosion, the coating peeling effect, mechanical properties and service life of steel structure. Therefore, the surface treatment of steel structure is an important guarantee and measure to obtain the excellent protective layer and prolong the service life of steel structure. Treatment method of glass fiber reinforced plastic prior to substrate
