Abstract

A glass drawdown coating system includes a container defining a glass ribbon path having a first side and a second side. At least one nanoparticle coater is located adjacent the first side and/or the second side of the glass ribbon path.

First claim

What is claimed is:

1. A glass drawdown coating system, comprising:
a container comprising a discharge slot configured to allow molten glass to flow down under gravitational force to form a glass ribbon having a first side and a second side;
a first nanoparticle coater located adjacent the first side of the glass ribbon;
a second nanoparticle coater located adjacent the first side of the glass ribbon and below the first nanoparticle coater; and
a third nanoparticle coater located adjacent the second side of the glass ribbon,
wherein the first nanoparticle coater, the second nanoparticle coater or the third nanoparticle coater comprises a housing, a nanoparticle discharge slot, and a first combustion slot configured to ignite a first flame, wherein the first flame is configured to heat a surface of the glass ribbon and to lower a viscosity of the surface of the glass ribbon to allow a nanoparticle to penetrate to a desired depth.

2. The system of claim 1 , wherein the first nanoparticle coater comprises:
the housing;
the nanoparticle discharge slot; and
the first combustion slot.

3. The system of claim 1 , wherein the nanoparticle discharge slot is connected to a nanoparticle source and a carrier fluid source.

4. The system of claim 3 , wherein the nanoparticle source comprises a vaporizer.

5. The system of claim 3 , wherein the nanoparticle source comprises metal oxide nanoparticles.

6. The system of claim 3 , wherein the nanoparticle source comprises luminescent and/or phosphorescent nanoparticles.

7. The system of claim 6 , wherein the nanoparticle source comprises phosphors.

8. The system of claim 6 , wherein the nanoparticle source comprises luminous nanocrystalline nanoparticles.

9. The system of claim 1 , wherein the first combustion slot is connected to a fuel source and an oxidizer source.

10. The system of claim 9 , wherein the fuel source comprises natural gas.

11. The system of claim 9 , wherein the oxidizer source comprises oxygen.

12. The system of claim 1 , wherein the first nanoparticle coater, the second nanoparticle coater or the third nanoparticle coater further comprises a second combustion slot, and wherein the nanoparticle discharge slot is located between the first combustion slot and the second combustion slot.

13. The system of claim 1 , wherein the first nanoparticle coater is connected to a first nanoparticle source and the second nanoparticle coater is connected to a second nanoparticle source.

14. The system of claim 13 , wherein the first nanoparticle source is different than the second nanoparticle source.

15. The system of claim 1 , including a fourth nanoparticle coater and a fifth nanoparticle coater located adjacent the second side of the glass ribbon.

16. The system of claim 15 , wherein the third nanoparticle coater is connected to a third nanoparticle source and the fourth nanoparticle coater is connected to a fourth nanoparticle source.

17. The system of claim 16 , wherein the third nanoparticle source is different than the fourth nanoparticle source.

18. The system of claim 1 , wherein the first nanoparticle coater, the second nanoparticle coater or the third nanoparticle coater further comprises a second combustion slot configured to ignite a second flame, wherein the second flame is configured to help smooth the surface of the glass ribbon wherein the nanoparticle was deposited.
