Abstract

A material coating system for an apparatus having a housing configured to contain a fluid is disclosed herein. A multi-layer coating is applied to the housing to mitigate damage caused by external factors. The multi-layer coating includes: a layer of a primer coating having anti-corrosive properties, a layer of a mid coating having mechanical and chemical properties capable of at least partially closing a hole in the housing to avoid fluid leakage and optionally a layer of a top coating having properties that resist ultraviolet radiation from passing therethrough.

Claims (47)

1. A system comprising:

an apparatus including a housing configured to contain a fluid;

a multi-layer coating applied to the housing;

wherein the multi-layer coating includes:

a layer of a primer coating;

a layer of a mid coating including mechanical and chemical properties capable of at least partially closing a hole in the housing; and

a layer of a top coating including properties that resist ultraviolet radiation from passing therethrough.

2. The system of claim 1 , wherein the layer of primer coating includes a thickness in a range of about 0.0001 to 0.010 inches.

3. The system of claim 1 , wherein the layer of primer coating includes a thickness in a range of about 0.0005 to 0.006 inches.

4. The system of claim 1 , wherein the layer of primer coating includes a thickness in a range of about 0.005 to 0.006 inches.

5. The system of claim 1 , wherein the layer of mid coating includes a thickness greater than about 0.001 inches.

6. The system of claim 1 , wherein the layer of mid coating includes a thickness greater than about 0.005 inches.

7. The system of claim 1 , wherein the layer of mid coating includes a maximum thickness of about 0.750 inches.

8. The system of claim 1 , wherein the layer of top coating includes a thickness in a range of about 0.0001 to 0.060 inches.

9. The system of claim 1 , wherein the layer of top coating includes a thickness in a range of about 0.0001 to 0.010 inches.

10. The system of claim 1 , wherein the layer of top coating includes a thickness in a range of about 0.0005 to 0.008 inches.

11. The system of claim 1 , wherein a chemical composition of the primer coating material includes:

about 10 to 30 weight percent of Titanium Dioxide;

about 1 to 5 weight percent of Magnesium Silicate (TALC);

about 5 to 10 weight percent of Zinc Phosphate;

about 1 to 5 weight percent of Xylene and mixed Isomers;

about 1 to 5 weight percent of Toluene;

about 1 to 5 weight percent of Methyl Amyl Ketone;

about 1 to 5 weight percent of Methyl Isobutyl Ketone;

about 5 to 10 weight percent of Methyl Ethyl Ketone;

about 5 to 10 weight percent of N-Butyl Acetate; and

about 1 to 5 weight percent of Ethylbenzene.

12. The system of claim 1 , wherein a chemical composition of the mid coating material includes:

a first portion defined by less than 60 weight percent of Diphenylmethane-4, 4′-diisocyanate (MDI) and less than 40 weight percent of Methylenediphenyl diisocyanate; and

a second portion defined by about 50 to 75 weight percent of alpha-(2-Aminomethylethyl)-omega-(2-aminomethylethoxy)-poly (oxy(methyl-1,2-ethanediyl)) and about 20.0 to 25 weight percent of diethylmethylbenzenediamine.

13. The system of claim 1 , wherein a chemical composition of the top coating material includes:

about 25 to 50 weight percent of Barium Sulfate;

about 10 to 25 weight percent of Siloxanes and Silicones, DI-ME, Methoxy PH, Polymer;

about 10 to 25 weight percent of 1, 6-Hexanediol diacrylate;

about 10 to 25 weight percent of Acrylated Urethane Oligomer;

about 1 to 10 weight percent of Isopropyl Alcohol;

about 1 to 10 weight percent of Titanium Dioxide;

about 1 to 10 weight percent of Xylenes (o-, m-, p-isomers); and

about 1 to 10 weight percent of Propylene Glycol Monomethyl Ether Acetate.

14. The system of claim 1 , wherein the apparatus includes an electrical inductive device, a heat exchanger, a radiator, a valve, a tap changer, instrumentation, and/or an electrical machine.

15. The system of claim 1 , wherein the primer coating includes anti-corrosive properties.

16. The system of claim 1 , wherein the multi-layer coating is operable for preventing leakage of fluid from the hole.

17. The system of claim 1 , wherein the layer of primer coating includes a thickness in a range of about 0.0001 to 0.060 inches.

18. The system of claim 1 , further comprising one or more sensors in sensed communication with the apparatus, the one or more sensors operable for determining a condition of a portion of the apparatus.

19. The system of claim 18 , wherein the sensors are smart sensors operable for collecting vibration, sound, pressure and/or temperature data.

20. The system of claim 19 , wherein the data is transmitted to a remote location, analyzed for optimizing performance and determining predictive maintenance.

21. The system of claim 20 , wherein data transmission means includes dedicated signal lines, Wi-Fi signals, radio frequency signals, microwave signals and/or Bluetooth signals in communication with the World Wide Web.
