The method of anti-corrosion of guardrail panels
The anti-corrosion method of corrugated guardrail manufacturers has a great relationship with the service life of guardrail panels. Generally speaking, the service life of highway guardrail panels is 5-10 years. The guardrail board is a fence welded to the supporting structure with metal mesh to prevent people and animals from entering the warning area. Guardrail plate isolation fences should be set on both sides of the highway and the first-class automobile highway. to prevent illegal encroachment on highway land.
One of the ways of corrugated guardrail manufacturers: zinc steel guardrail dipping, is a plastic coating process, that is, the plastic is coated on the substrate (generally metal), now the more mature dipping method in China is: powder dipping method, it originated from the vulcanized bed method, the so-called vulcanized bed was originally applied to oil contact decomposition in the Winkler gas generator furnace, and then developed a solid-gas two-phase contact process, and then gradually used in metal coating. Dipping is to evenly spray plastic powder on the metal to form a plastic film by heating the metal, or heat the impregnation liquid into the metal parts to cool the plastic and coat the metal surface. This process is widely used because it does not require molds, low processing costs, easy molding, and can process various shapes.
We use heavy anticorrosive coatings for guardrail panels, which refers to a type of anticorrosive coating that can be applied in a relatively harsh corrosive environment compared with conventional anticorrosive coatings, and has a longer protection period than conventional anticorrosive coatings for guardrail panels.
For the guardrail board to use heavy anti-corrosion coating for treatment: for how the guardrail board can be used under harsh conditions and has a long-term anti-corrosion life, heavy anti-corrosion coating can generally be used for more than 10 or 15 years in the chemical atmosphere and marine environment, even in acid, alkali, salt and solvent media, and under certain temperature conditions, it can be used for more than 5 years. Thick film is an important sign of heavy anticorrosive coatings. Generally, the dry film thickness of anticorrosive coatings is about 100μm or 150μm, while the dry film thickness of heavy anticorrosive coatings is more than 200μm or 300μm, and there are 500μm~1000μm, or even as high as 2000μm.
Corrugated guardrail manufacturers use concrete pouring parts, low project cost, high strength, good overall stability, color plastic layer has good corrosion resistance and decorative effect, and the fence board fence is harmonious and beautiful as a whole. The concrete column can be made by the local surplus labor, simple mold, only need to take the frame mesh from our factory, and the guardrail board can greatly reduce the project cost, which is the ideal selection plan for your construction fence. The guardrail board has the characteristics of durability, beauty, wide vision and good protective performance.
