Abstract

The invention discloses a baking finish process of a workpiece for a radar. The baking finish process of the workpiece for the radar is characterized in that abrasive paper used in a step (1) adopts No. 400 waterproof abrasive paper for the first time and No. 800 waterproof abrasive paper for the second time; the uneven rusty spots on the surface of the workpiece can be thoroughly cleaned through polishing for two times; mixed acid in a step (3) is a mixed solution of concentrated nitric acid and hydrofluoric acid with the mass ratio of 3 to 2, can be used for processing oil stains and the rusty spots on the surface of the workpiece, and can also form an oxidation film on the surface; in a step (4), the workpiece is dried by adopting an infrared drying technology at the temperature of 80 DEG C, and the drying time is 30min, so that the workpiece can be quickly dried through the process, the time spent for the process is shortened, and the process efficiency is improved; acid used for adjusting the power of hydrogen in a step (5) is KH2PO4 / H3PO4, alkali used for adjusting the power of hydrogen in the step (5) is NaHCO3 / NaOH, and the acid and the alkali are buffer systems, can resist the change of the power of hydrogen of the surface of the workpiece while adjusting the power of hydrogen; and the forced baking temperature used in a step (10) is 185 DEG C, and the workpiece is processed at higher temperature, so that the production speed can be improved.

Description

technical field [0001] The invention relates to the processing field of radars and parts thereof, in particular to a paint-baking process for workpieces used in radars. Background technique [0002] Radar is an electronic device that uses electromagnetic waves to detect objects. The radar emits electromagnetic waves to irradiate the target and receives its echo, thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the distance change rate (radial velocity), azimuth, and height. The thin-walled parts applied to the surface of the radar are very important components. They are laid on the surface of the radar to emit and gather electromagnetic waves. Therefore, the surface performance requirements of this kind of thin-walled parts are very high. In order to use long-term outdoor operations, it should have a strong surface hard bottom to prevent its deformation, and it should also have strong corrosion resistance. At pre...
