Problems solved by technology

[0003] However, due to the formation of a functional film with properties different from that of the glass substrate, there is a problem that the adhesion between the glass substrate and the functional film is poor, and the film is easily peeled off due to operations such as wiping. The surface of the glass substrate contacts to form a porous structure on the glass surface (hereinafter also referred to as "etching") to form an anti-reflection film (Patent Documents 1 to 3)

Embodiment A1

[0074] Using the twin-fluid injector 10 used in the atmospheric pressure CVD method, such as figure 1 As shown in the schematic diagram, a gas containing hydrogen fluoride was brought into contact with the surface of the glass substrate of the original plate A shown in Table 1. The surface contacting the hydrogen fluoride-containing gas serves as a molten metal bath non-contact surface of the glass substrate produced by the float method.

[0075] That is, mix HF0.56SLM (in terms of gas in the standard state, liters per minute) and nitrogen (N 2 ) The gas obtained by 9SLM is heated to 150°C, at a flow rate of 64cm / s from figure 1 The central slit 1 is shown spraying towards the glass substrate and 245.5 SLM of N from the outer slit 2 onto the glass substrate 2 . The gas flows on the substrate 20 through the channel 4 , and the gas in an amount twice the jet flow rate is discharged through the exhaust slit 5 . The temperature and flow velocity of the gas were measured using ...

Embodiment A2、A3 and A4

[0077] Except that the temperature of the glass substrate in Example A1 is set to 560°C (Example A2), 400°C (Example A3) or 620°C (Example A4), the surface of the glass substrate is carried out in the same manner as in Example A1. deal with.

Embodiment A5

[0079] The surface treatment of the glass substrate was performed in the same manner as in Example 1A except that the amount of HF in the central slit 1 was set to 1.12 SLM.

Abstract

The present invention efficiently obtains in a short period of time a glass substrate having a low refraction index layer exhibiting excellent properties in which the refraction index is low. A glass substrate is produced by subjecting at least one surface of a glass substrate, that is being conveyed when the temperature of the glass substrate is within 400°C and Tg+60°C (Tg being the glass transition temperature of the glass substrate), to surface treatment by bringing the glass substrate into contact with liquid or gas containing molecules having fluorine atoms in the structure thereof.

Description

technical field [0001] The present invention relates to a method for the manufacture of surface-treated glass substrates. In particular, it relates to a method of making a fluorine-based gas in contact with a glass substrate during transportation to effectively form a layer with a lower refractive index than glass (hereinafter also referred to as "low refractive index layer") on the surface of the glass, and the method for the surface of the glass A method for producing a chemically strengthened glass in which a treated glass substrate is chemically strengthened. Background technique [0002] In the past, glass substrates used in applications requiring light transmission, such as glass for building materials, glass for automobiles, glass for displays, optical elements, glass substrates for solar cells, window glasses, optical glasses, and spectacle lenses, were used to improve light transmission. rate, there is a situation where an anti-reflection film is formed on the surf...
