Embodiment 1
[0042] Embodiment 1 A kind of two-spray-one-solid equipment using composite coating anti-corrosion workpiece
[0043] like Figure 1-Figure 6 As shown in common, the present invention provides a two-spray and one-fix equipment for anti-corrosion workpieces using composite coatings, including a shot blasting and derusting device 1, a primary spraying recovery device 2, a primary spraying system 3, a secondary spraying system 4, and a secondary spraying Recovery device 5 , catenary conveying system 6 , curing furnace device 7 , catenary drive and whole line control system 8 .
[0044]The catenary conveying system 6 includes a catenary 61 , the bottom of which is connected to a catenary trolley 63 through a suspension rod 62 ; The catenary conveying system 6 is used for hanging and conveying the column workpiece 11. During the conveying process, the processes of shot blasting, primary spraying, secondary spraying and curing are completed in sequence.
[0045] The primary sprayi...
Embodiment 2
[0061] Embodiment 2 A kind of two-spray and one-solid process using composite coating anti-corrosion workpiece
[0062] like Figure 1-Figure 6 Commonly shown, the present invention provides a two-spray-one-solid process for a composite coating anti-corrosion workpiece, including the steps of shot blasting and rust removal, primary spraying, secondary spraying and joint curing.
[0063] Among them, shot blasting and derusting treatment is used to degreasing and derusting the surface of the suspended column workpiece, and the quality of the surface anchor pattern is required to reach Sa2.5 level.
[0064] Among them, the primary spraying treatment is used to complete the electrostatic spraying of the epoxy zinc-rich primer, and the secondary spraying treatment is used to complete the electrostatic spraying of the polyester flour.
[0065] In both the primary spraying treatment and the secondary spraying treatment, the column workpiece is righted, so that the swinging column wo...
