Description
Description

The guardrail uses the deformation of soil foundation, column, beam, and endurance board to absorb the collision energy, and force the out-of-control vehicle to change direction and return to the normal driving direction to prevent the vehicle from rushing out of the road, so as to protect the vehicle and passengers and reduce the accident caused by the accident. loss.
According to the anti-collision grade, the highway wave guardrail can be divided into A grade and S grade. The S-level guardrail is a reinforced type, which is suitable for use in particularly dangerous road sections on the roadside, and the A-level guardrail is used for special roads. The commonly used roadside corrugated beam guardrails can be divided into five grades: B, A, SB, SA, and SS according to the anti-collision level.
 

·Degreasing can be done by chemical degreasing or water-based metal degreasing cleaning agent until the guardrail is completely soaked with water.
 
· For pickling, H2SO4 15%, thiourea 0.1%, 40~60℃, or HCl 20%, hexamethylenetetramine 1~3g/L, 20~40℃ can be used for pickling. The addition of corrosion inhibitors can prevent excessive corrosion of the substrate.
 
·The immersion flux maintains a certain activity on the guardrail before immersion plating to enhance the combination of the coating and the substrate. NH4Cl15%~25%, ZnCl22.5%~3.5%, 55~65℃, 5~10min. In order to reduce the volatilization of NH4Cl, glycerol can be appropriately added.

·Hot-dip galvanizing should control the temperature of the zinc bath, the dipping time and the speed at which the guardrail is removed from the zinc bath.

·After finishing and plating, the finishing of the guardrail is mainly to remove the residual zinc and zinc nodules on the surface, which can be done by vibration or manual methods.
 
·Passivation improves the atmospheric corrosion resistance of the guardrail surface, reduces or prolongs the appearance time of white rust, and maintains a good appearance of the coating. All are passivated with chromate, such as Na2Cr2O780~100g/L, sulfuric acid 3~4ml/L.
 
·Cooling is generally water-cooled, but the temperature should not be too low to prevent the guardrail, especially the casting, from cracking the matrix structure due to the chilling shrinkage.
 
·Check that the appearance of the coating is bright, meticulous, free from sagging and wrinkling. Thickness inspection can use coating thickness gauge, the method is relatively simple.
