Fluorocarbon resin high-strength anti-corrosion bridge and preparation method thereof

Abstract

The invention discloses a fluorocarbon resin high-strength anti-corrosion and fireproof bridge which comprises a bridge base, wherein the surface of the bridge base is coated with a metal coating; fluorocarbon resin powder is sprayed on the metal coating through electrostatic powder to form a fluorocarbon resin powder layer with thickness of 70-80 microns; the fluorocarbon resin powder layer has aflat surface and fluorocarbon resin powder in fusion bonding with the metal coating below the surface. The fluorocarbon resin high-strength anti-corrosion and fireproof bridge disclosed by the invention has the advantages of good corrosion resistance, no stripping of anti-corrosion layer, long service life, strong fire resistance and high strength.

Description

technical field [0001] The invention relates to a cable bridge and a preparation method thereof, in particular to a fluorocarbon resin high-strength anti-corrosion bridge and a preparation method thereof. Background technique [0002] The surface of traditional cable trays is usually added with electro-galvanized, hot-dip galvanized or aluminum coatings, or sprayed to increase the protective layer to improve anti-corrosion performance. Metal coatings and plastic sprayed layers are easy to peel off and change color during long-term use. The corrosion effect is not good and the service life is short; in the prior art, most anti-corrosion cable bridges are painted on the metal coating, although the corrosion condition of the steel bridge from the inside to the outside has been improved, but its surface corrosion resistance is still not up to the standard. To meet the requirements of long-term use in various harsh weather environments and strong chemical corrosion conditions suc...

Problems solved by technology

[0002] The surface of traditional cable trays is usually added with electro-galvanized, hot-dip galvanized or aluminum coatings, or sprayed to increase the protective layer to improve anti-corrosion performance. Metal coatings and plastic sprayed layers are easy to peel off and change color during long-term use. The corrosion effect is not good and the service life is short; in the prior art, most anti-corrosion cable bridges are painted on the metal coating, although the corrosion condition of the steel bridge from the inside to the outside has been improved, but its surface corrosion resistance is still not up to the standard. To meet the requirements of long-term use in various harsh weather environments and strong chemical corrosion conditions such as acids and alkalis, the cable tray cannot be repaired after the surface peels off, and can only be replaced with a new cable tray, which wastes resources and increases manufacturing costs; One tenth of the world's steel output is lost due to corrosion. Therefore, energy saving, emission reduction and corrosion reduction are major issues in today's society.
