In November 8th, the Danyang Road overpass bridge project in Heze, Shandong, under the traction of two 350 ton continuous jack, the main bridge on the east side of Shandong Heze Danyang Road overpass, with a self weight of 24 thousand and 800 tons, turned 81.67 degrees counterclockwise, achieving precise docking with the approach bridge. At this point, the largest cable-stayed bridge in the world has successfully turned "turn". Danyang Road overpass 2031 meters in length, across Beijing, new Yanzhou railway and Heze yard. In order to reduce the interference of construction on the existing railway line and ensure the safety of railway operation, the construction department adopts the technology of "build first and then turn", first construct the bridge body along the parallel direction of the railway, then turn the built bridge along the counter clockwise direction to the design location.

After a successful docking, engineering, which is the anticorrosive construction of this project, the anti-corrosion operation is divided into two parts. The first part is the bridge steel structure anticorrosion, considering the appearance of the bridge, the coating should not only have excellent corrosion resistance, weather resistance must be good and excellent the gloss and color performance, Hangzhou Yasheng paint recommended the use of fluorocarbon paint as topcoat.

1, fluorocarbon paint excellent anticorrosion performance, thanks to the excellent chemical inertness, film of acid and alkali, salt and other chemical substances and a variety of chemical solvents, to provide protection for the substrate; the tough film, high surface hardness, impact resistance, anti buckling, good abrasion resistance, showing excellent physical and mechanical properties.

2, fluorocarbon paint is maintenance free, self cleaning, fluorocarbon coating has low surface energy and surface dust by rainwater self-cleaning, excellent hydrophobicity (maximum absorption rate less than 5%) and friction coefficient, minimum oil repellency (0.15 - 0.17), not sticky fouling, good antifouling properties.

3, strong adhesion, has excellent adhesion on copper, stainless steel and other metals, such as polyester, polyurethane, vinyl chloride and other plastics, cement and composite materials, and basically shows that it is suitable for any material. High decoration - in the 60 degree lustreter, it can reach more than 80% high gloss.

4, super long weatherability. The coating contains a large number of F--C bonds, which determines its super stability, no pulverization and no fading. Its service life is as long as 20 years. It has better performance than any other coatings. Excellent construction - double component packing, long storage period and convenient construction.

Supporting the primer and paint can choose between epoxy zinc rich primer and epoxy micaceous iron oxide paint, fluorocarbon paint more related, you can also consult the Hangzhou Yasheng Co., ink painting staff.

On the other hand bridge anti-corrosion, anti-corrosion is the concrete structure, concrete structure in the anti-corrosion, we must first do a penetration of the primer, epoxy primer for bridge penetration. It has strong penetration, enhancement and sealing effect on concrete and brick surface, and has excellent alkali resistance. Coating on the concrete substrate can effectively prevent the waste of the rear coating and enhance the adhesion between the coating and the coating. After the coating, the coating product which is consistent with the steel structure anticorrosion can be selected. The epoxy zinc rich primer underneath, the epoxy cloud iron intermediate paint with fluorocarbon paint.
