In order to solve the above problems, the technical solution of the present invention is as follows:
a steel plate rust removing device comprises a polishing cleaning head, wherein the polishing cleaning head is a disc, a replaceable steel wire brush is arranged on the disc, and the disc is connected with a driving motor; the polishing cleaning head is connected with a long handle, the rear end of the handle is connected with a cable, and a control switch is arranged on the handle.
The middle part of the polishing and cleaning head is provided with a blowing nozzle, and fan blades are arranged in the blowing nozzle and connected with a motor shaft of a driving motor.
The disc is connected with a motor shaft through a gear.
A method for removing rust from a steel plate,
1) firstly, uniformly spraying a rust remover on a steel plate needing rust removal;
2) then, derusting and polishing the steel plate by using derusting equipment with a steel wire brush;
3) and finally spraying antirust paint on the steel plate.
The rust remover comprises the following components: 18 parts of hydrochloric acid; 1 part of dextrin; 3 parts of sodium molybdate; 2 parts of phosphoric acid; 60 parts of water; and 8 parts of glycerol.
After the step 1), the steel plate is aired for 3-5 minutes to be aired, and then the step 2) is carried out.
