Embodiment Construction
[0005] This specific embodiment mainly includes the following technological process, 1, zinc spraying selects 100% metal zinc to carry out, and zinc wire adopts diameter below 2mm; 2, thermal spraying zinc adopts QD8 type arc spraying method to spray zinc; The distance between the light shield and the workpiece is 100mm; 4. The thickness of the coating should be measured at any time during the spraying process; 5. The center line of the jet stream cone should be perpendicular to the base surface to be sprayed; 6. Adjust the surface speed of the spray gun at any time; 7. Zinc spray inspection, check whether there is oily zinc slag and zinc dripping; 8. Thickness inspection. The invention guarantees the specification of the technology in the zinc spraying process, increases the inspection steps, reduces various zinc spraying defects, and ensures the final tower frame spraying quality.

The invention provides a zinc spraying technology for surfaces of wind tower bodies, which relates to a surface treatment process of wind tower bodies, in particular to a sand blasting process for corrosion protection and coating of the wind tower bodies. The process mainly includes the following technological processes: 1. 100 percent metal zinc and zinc wires with diameters of shorter than 2mm are adopted for the zinc spraying; 2. a QD8 type electric arc spraying means is adopted for the hot zinc spraying; 3. in the spraying of the electric arc, the distance between a pellicle and a workpiece is 100mm; 4. cladding thickness is measured at any moment in the spraying process; 5. a central line which ejects a conical flowing surface is perpendicular to a base surface which is sprayed and plated; 6. the surface velocity of a spraying gun is adjusted at any moment; 7. zinc spraying checking includes whether zinc slags with greasy dirt exist or zinc drops; and 8. thickness is checked. The process ensures the process standard in the zinc spraying process and adds the checking steps, which reduces various zinc spraying flaws and ensures the final tower spraying quality.
Description
technical field [0001] The invention relates to a wind tower body surface treatment process, in particular to a zinc spraying process for anti-corrosion coating of the wind tower body. Background technique [0002] The zinc spraying process of the surface treatment process of the existing wind power tower towers is relatively simple, and the requirements for the zinc spraying process are not high, which leads to the subsequent spraying quality not up to the standard, and ultimately affects the spraying quality of the tower. Contents of the invention [0003] The object of the present invention is a process of spraying zinc on the surface of a wind tower body. The invention solves various instabilities in the surface treatment quality of the downwind tower body caused by various defects in zinc spraying in the existing traditional process, thereby affecting the final spraying quality. [0004] The present invention mainly includes the following technological processes: 1. ...
