Anti corrosion paint for condenser

Abstract

The present invention discloses an anticorrosive coating for steam condenser. Its raw material composition includes (by wt%) 80-88% of phenol formaldehyde epoxy resin, 1-2% of dibutyl (0-)phthalate, 8-13% of solidifying agent and 3-8% of superfine ceramic powder.

Description

Technical field [0001] The present invention relates to a fine chemical, more specifically to a paint. Background technique [0002] Condenser is one of the important equipment of thermal power plant. It is a huge box with up to tens of thousands of tubes. Due to the industrial pollution of water quality and the shortage of water resources, the increase of the concentration ratio of circulating water, the corrosion of condenser tube plates, the erosion corrosion of nozzles and the penetration and leakage of expansion ports are practical problems in every condenser. Pipe leakage often occurs, so that the cooling water containing impurities enters the steam side of the condenser and mixes into the clean condensed water. On the one hand, the vacuum degree of the condenser will continue to change, and on the other hand, it will Fouling, worsening heat transfer, reduces the power generation efficiency of the system. The usual way to solve this problem is to replace the condense...

Problems solved by technology

Pipe leakage often occurs, so that the cooling water containing impurities enters the steam side of the condenser and mixes into the clean condensed water. On the one hand, the vacuum degree of the condenser will continue to change, and on the other hand, it will Fouling, worsening heat transfer, reducing power generation efficiency of the system

The usual way to solve this problem is to replace the condenser tube, which is difficult to construct, has a long construction period, and the cost of maintenance and repair is also high
