Large area of enamel damage to the enamel kettle, equipment to be sent to the manufacturer re-enameled, the cost is about 1/4 of the new purchase. Minor damage area can be repaired locally. It can be repaired by on-site rapid repair without dismantling the equipment. It can be repaired only by opening the manhole. It can be put into use 24 hours after repair. Field repair agents include epoxy resin, polytetrafluoroethylene resin, high-performance enamel repair agents and a growing number of polymer composite enamel repair agents.

  Macromolecular composite enamel field repairing agent is a two-component composite material, which is made of polymer, alloy steel powder or wear-resistant ceramic powder as the base material and matched with curing agent. Compared with ordinary resin-based repairing agents, polymer composite materials rely on their own finer polymer structure, making the material itself has stronger adhesion and excellent corrosion resistance, corrosion resistance, high polymer can even penetrate into the metal, forming a more compact polymer composite protective layer. The technology system is more applied both inside and outside. It has high chemical stability and good physical and mechanical properties. Repairing chemical enamel equipment with polymer composites not only saves non-ferrous metals, but also has the advantages of simple repairing process, low cost, short repair time, corrosion resistance and wear resistance. It is worth exploring and popularizing. The quick repair of enamel kettle with enamel repairing agent is simple, rapid, effective and economical.
