Problems solved by technology
[0004] The epoxy resin mixed with quartz sand process has higher hardness, but it has the disadvantage of brittle texture and is not resistant to impact, and it is not suitable for the working condition of uneven water flow and impact in the lower part of the bed under the working condition of finishing treatment under half load.

Embodiment Construction
[0018] The repairing anti-corrosion material used in the preferred embodiment of the present invention is the high-temperature cermet HTX (Cerami-Tech HTX) in the Zotac series products of British Ewood Company. This product has better high temperature resistance and is suitable for long-term operation in high temperature environments. Fluid equipment such as water tanks, pumps, heat exchangers, storage tanks, reactors, etc. The repair method of the present embodiment comprises:
[0019] 1. Preferably, attention should first be paid to the technological conditions during repairing, that is, the pretreatment of the repairing environment: the ambient temperature during construction should be between 18-25°C, and the relative humidity should be lower than 90%. The surface of the equipment substrate should not be wet. The environment is free from oil pollution and smoke.
[0020] 2. Repairing the surface of the substrate to remove rust and hair: use iron ore to sandblast the surf...

Abstract
The invention relates to a method for repairing liner rubber of an air-cooling condensation water fine treatment system, which comprises the following steps: a. burr descaling for repairing the substrate surface; b. paint construction; and c. coating maintenance. Due to the adoption of novel anticorrosive material-high temperature metal ceramics (HTX ceramics), the invention does not use the traditional repairing process using liner rubber and resin, thereby solving the technical problem that no proper repairing materials are available when the traditional technique is adopted on site, and keeping the equipment to stably operate for a long time. The allowable working temperature and pressure in the invention are far higher than the working conditions of the condensation water fine treatment, the high temperature metal ceramics have strong adhesive force with the liner rubber and steel substrate, and have certain toughness. When being used for on-site construction, the invention is feasible, has the advantages of high operability and simple technique, and can satisfy the requirements for the on-site construction by simply adopting the existing tool set equipment.
Description
technical field [0001] The present invention relates to a rubber-lined repair method, in particular to a rubber-lined repair method for an air-cooled condensate polishing treatment system, and more specifically, to a repair of the rubber-lined anti-corrosion layer inside the high-speed yin-yang bed of the air-cooled condensate polishing system method. Background technique [0002] Most of the existing air-cooled condensate water polishing equipment is lined with rubber for anti-corrosion, and the water temperature is high (74°C) and the working pressure is high (4.0MPa). When the anti-corrosion of the equipment is damaged, it is difficult to meet the requirements of strength and working conditions if ordinary rubber-lined maintenance materials and repair techniques for water treatment equipment are used. [0003] Existing rubber-lined maintenance techniques include self-vulcanized rubber plate repair and epoxy resin mixed quartz sand repair. Among them, the allowable worki...
