Description

Self-cleaning glass for shower room

Technical Field

The invention relates to the field of glass, in particular to self-cleaning glass for a shower room.

Background

"easy-to-clean glass", also commonly referred to commercially and figuratively as "self-cleaning glass", refers to glass having a surface with a coating of a particular paint that makes it difficult for dirt or dirty liquid to adhere to the surface of the glass or to be relatively easily washed away by water.

And the special coating is classified into hydrophobic type and hydrophilic type according to the principle of realizing self-cleaning effect. The surface of the hydrophobic coating has super hydrophobicity, when water falls on the surface of the hydrophobic coating, the contact angle of a water drop is larger than 110 degrees, so that the water is positioned on the surface of the coating in the form of water drops, if the surface of the coating is inclined or vertical, the water drops fall, namely, the water is not attached, and dust and dirt fall together with the water drops. The surface of the hydrophilic coating has super-hydrophilicity, when water falls on the surface of the hydrophilic coating, the contact angle of water drops is less than 10 degrees, and then the water expands on the surface due to self-tension to form a water film instead of adhering to the water drops, and the water film makes stains difficult to adhere to.

In the prior art, the self-cleaning glass is used for a shower room by utilizing the characteristics of the self-cleaning glass. When the shower is taken, the water flow splashes on the inner wall of the shower room, and the water flow can quickly slide off, so that water drops are prevented from being attached to the inner wall of the shower room. Because the environment in the shower room is humid, a breeding environment is provided for bacteria, so a large amount of bacteria can grow in the shower room, and certain hidden troubles are caused for the health of people.
