Problems solved by technology

[0004] The anti-corrosion coating during operation can only be carried out on site at night after the train is out of service. The atmospheric environment at night and many unfavorable conditions for on-site operations make it very difficult to effectively implement the coating process when the construction conditions are difficult to control. Increase the cost of anti-corrosion coating, but also affect the construction quality of anti-corrosion coating

Embodiment 1

[0037] Such as figure 1 and figure 2 As shown, the PC beam steel seam plate anti-corrosion and wear-resistant coating method includes the following steps:

[0038] S1, performing pretreatment on the steel joint plate 1, so that the surface to be painted of the steel joint plate 1 is clean, dust-free, rust-free, and grease-free, and the roughness of the steel joint plate 1 reaches a preset level Require;

[0039] S2, performing co-infiltration anti-corrosion treatment on the pretreated surface of the steel joint plate 1 to be coated, so that a layer of metal alloy co-infiltration anti-corrosion layer 2 is formed on the surface to be coated of the steel joint plate 1;

[0040] S3, coating the anti-corrosion and wear-resistant paint film 3 on the metal alloy co-infiltrated anti-corrosion layer 2, and wait until the anti-corrosion and wear-resistant paint film 3 is dry.

[0041] The pretreatment process in S1 is specifically as follows: first, the surface of the steel seam pla...

Embodiment 2

[0068] Such as figure 1 and figure 2 As shown, in the PC beam steel seam plate of this embodiment, the steel seam plate is coated with an anti-corrosion and wear-resistant coating 3, and the anti-corrosion and wear-resistant coating 3 is coated on the The surface to be painted of the steel seam plate 1 . The PC beam steel joint plate of this embodiment has a long service life and good anti-corrosion and wear-resisting effects.

Abstract

The invention relates to a painting method for an antiseptic wear-resistant coating of a PC joist steel jointing plate and the PC joist steel jointing plate. The painting method comprises the following steps: S1, carrying out pretreatment to a steel jointing plate so as to enable the surface to be painted of the steel jointing plate to be clean and free of dust, rust and grease, and enabling the roughness of the steel jointing plate to meet the preset requirement; S2, carrying out co-penetrated antiseptic treatment to the surface to be painted of the steel jointing plate subjected to the pretreatment so as to enable the surface to be painted of the steel jointing plate to form a co-penetrated antiseptic layer for metal alloy; and S3, coating antiseptic wear-resistant paint film on the co-penetrated antiseptic layer for the metal alloy to obtain the antiseptic wear-resistant coating after the antiseptic wear-resistant paint film dries and solidifies. The painting method provided by the invention increases the wear resistance and skid resistance of the steel jointing plate, prolongs the normal tenure of use of the antiseptic wear-resistant coating of the steel jointing plate, reduces on-site maintenance in later period, enables a train to normally travel and is safe and reliable.

Description

technical field [0001] The invention relates to an anti-corrosion, wear-resistant and anti-slip method for PC rail beam steel joint plates, in particular to a method for coating anti-corrosion and wear-resistant coatings on PC beam steel joint plates and the PC beam steel joint plates. Background technique [0002] The straddle monorail is composed of PC track beams, connecting beams, steel track beams, turnout beams, etc. PC track beam steel joint plates (finger plates) are used at the joints between beams. [0003] Due to the typical acid rain characteristics in Chongqing area, coupled with high temperature, high humidity and man-made pollution, the air environment in Chongqing is very bad, and the original surface coating of the steel joint plate only meets the anti-corrosion performance requirements on the surface of the steel material . The surface of the original anti-corrosion coating has been rolled and rubbed by train tires for a long time, which will gradually wea...
