Embodiment

[0014] Embodiment: Assembly type zinc-steel guardrail assembly line production process, the steps are as follows:

[0015] According to the design drawings of the assembled guardrail, the raw material zinc steel profiles are cut and processed into various assembled workpieces, including handrails, horizontal tubes, vertical tubes, columns, and horizontal tube column connectors, etc., and are punched according to the designed installation holes.

[0016] Degreasing: Soak the workpiece in water containing 8%~10% alkaline degreaser by weight for 10~15 minutes for degreasing treatment to remove the oil on the surface of the workpiece.

[0017] Phosphating: Take out the degreased workpiece and rinse it with clean water, then soak it in water containing 10%~12% zinc-based phosphating solution by weight for 10 minutes for phosphating treatment. Its purpose is to provide anti-corrosion protection for metal workpieces, be used as a primer before painting, improve the adhesion and anti-...

Abstract

The invention discloses an assembled zinc steel guardrail production technology. The assembled zinc steel guardrail production technology includes the steps of putting a workpiece into water containing degreaser to soak and degrease the workpiece, then, putting the workpiece into water containing fine zinc phosphating solution to soak and process the workpiece in a phosphating mode, taking out the workpiece to put the workpiece into water containing a sealing agent so as to soak and passivate the workpiece, and finally taking out the workpiece to dry the workpiece. Organic zinc epoxy powder is sprayed on the dried workpiece, and the workpiece is placed into a 185-200 DEG C drying oven to be dried after the spraying; the workpiece is taken out to be cooled; pure polyester colorful powder is sprayed on the workpiece again, the workpiece is placed into the 185-200 DEG C drying oven to be dried after the spraying, and then the workpiece is taken out to be cooled; finally, tests are performed on the workpiece, and workpieces are packaged separately. The assembled guardrail machined with the technology is high in zinc steel material strength, a protective layer is formed on the surface after the treatment, and the assembled zinc steel guardrail has strong corrosion resistance and can be exposed outdoors for a long time without rusting.

Description

technical field [0001] The invention belongs to the field of production of guardrails for buildings and the processing technology of guardrail materials, in particular to a production process of assembled zinc-steel guardrails. Background technique [0002] Guardrails are widely used in residential and outdoor buildings as decoration and safety isolation facilities. Since the guardrail is exposed to the outside for a long time, in order to achieve safety and reliability, the guardrail is required to have strong hardness and corrosion resistance. Although the guardrail made of steel is strong enough, its corrosion resistance and oxidation resistance are weak. After long-term corrosion, the guardrail structure is damaged, which is prone to safety hazards and public safety accidents. Contents of the invention [0003] In view of the above problems, the present invention designs an assembled guardrail made of zinc steel material, and develops an advanced material processing t...
