Embodiment 1
[0020] refer to figure 1 , The bolt connection pair includes a bolt with a screw head 1 and a screw rod 2 , and a nut 3 and a washer 4 screwed on the screw rod 2 . A surface treatment process for a bolt connection pair. First, galvanizing is performed on the surface of the bolt connection pair. The galvanizing method is Dacromet galvanizing. The steps are:
[0021] A: Prepare lubricant, which is composed of molybdenum disulfide, dry film lubricant and deionized water. The mass ratio of molybdenum disulfide: dry film lubricant: deionized water is 1:15:100, and the dry film lubricant The agent is the GLEITMO lubricant produced by German Fuchs Oil Group, and the particle size of molybdenum disulfide is 2000 mesh. The dry film lubricant and molybdenum disulfide are added to deionized water and stirred evenly;
[0022] B. Put the lubricant prepared in step A in the centrifuge, immerse the galvanized bolt connection pair into the lubricant prepared in step A, and turn on the centr...
Embodiment 2
[0026] refer to figure 1 , The bolt connection pair includes a bolt with a screw head 1 and a screw rod 2 , and a nut 3 and a washer 4 screwed on the screw rod 2 . A surface treatment process for a bolt connection pair. First, galvanizing is performed on the surface of the bolt connection pair. The galvanizing method is hot-dip galvanizing. After galvanizing, a secondary surface treatment is performed. The secondary surface treatment The steps are:
[0027] A: Prepare lubricant, which is composed of molybdenum disulfide, dry film lubricant and deionized water. The mass ratio of molybdenum disulfide: dry film lubricant: deionized water is 1:15:50, and the dry film lubricant The agent is the GLEITMO lubricant produced by German Fuchs Oil Group, and the particle size of molybdenum disulfide is 2000 mesh. The dry film lubricant and molybdenum disulfide are added to deionized water and stirred evenly;
[0028] B. Put the lubricant prepared in step A in the centrifuge, immerse the...
Embodiment 3
[0032] refer to figure 1 , The bolt connection pair includes a bolt with a screw head 1 and a screw rod 2 , and a nut 3 and a washer 4 screwed on the screw rod 2 . A surface treatment process for a bolt connection pair. First, galvanizing is performed on the surface of the bolt connection pair. The galvanizing method is Dacromet galvanizing. The steps are:
[0033] A: Prepare lubricant, which is composed of molybdenum disulfide, dry film lubricant and deionized water. The mass ratio of molybdenum disulfide: dry film lubricant: deionized water is 1:15:60, and the dry film lubricant The agent is the GLEITMO lubricant produced by German Fuchs Oil Group, and the particle size of molybdenum disulfide is 1980 mesh. The dry film lubricant and molybdenum disulfide are added to deionized water and stirred evenly;
[0034] B. Put the lubricant prepared in step A in the centrifuge, immerse the galvanized bolt connection pair into the lubricant prepared in step A, and turn on the centri...
