The ultra-thin molten glass produced by the float process flows into a tin bath during forming, the molten glass floats on the surface of high-temperature molten tin with high relative density, and under the combined action of gravity and surface tension, the molten glass spreads and flattens on the surface of the molten tin to form flat and smooth glass with certain width and thickness, so that inevitable ion exchange and diffusion processes exist between the glass and the molten tin. However, the upper surface of the glass is not contacted with molten tin when the glass is formed in a tin bath, so that the ion quantity of the upper surface and the lower surface of the glass is different, when the float glass is subjected to integral chemical toughening, because the tin surface has ion blocking, but the non-tin surface does not have ion blocking, after the chemical toughening, because the ion exchange quantity of the tin surface and the non-tin surface is uneven, the stress of the upper surface and the lower surface of the glass is different, the surface can generate a warping phenomenon, and the large-scale production and use of the float glass are greatly influenced.
Therefore, a processing technology for preventing the uneven amount of ions on the upper and lower surfaces of float glass when the float glass enters a chemical toughening process and reducing the warping degree of the float glass after chemical toughening is needed.

The invention provides a processing technology for reducing warping degree of float glass after chemical tempering and glass, and the technical scheme of the invention is further described below by combining with the accompanying drawings, but the scope of the invention is not limited.
As shown in fig. 1, the present invention provides a processing technique for reducing warpage of float glass after chemical tempering, and referring to fig. 1, the processing technique comprises the following steps:
s1: making the ultra-thin glass liquid produced by the float process flow into a tin liquid tank to prepare smooth and flat float glass, wherein one side of the float glass close to the tin liquid tank is a tin surface, and the other side of the float glass far away from the tin liquid tank is a non-tin surface;

S6: and cleaning and drying the float glass with the thickness within the standard, and then chemically strengthening the dried float glass.
The ultrasonic cleaning is divided into a first ultrasonic cleaning and a second ultrasonic cleaning; the first ultrasonic cleaning is to place the float glass in an acetone solution for ultrasonic cleaning for 5-10 min; and the second ultrasonic cleaning is to place the float glass in distilled water for ultrasonic cleaning for 10-15 min.
S3 includes the steps of:
s3-1: turning on an ultraviolet light source of a glass tin surface detector;
s3-2: attaching it to one side of a float glass;
s3-3: observing from the other side of the float glass, and if milky brilliance is observed, the surface attached by the glass tin surface detector is a tin surface; if no brilliance or blue-violet light is observed, the surface attached by the glass tin surface detector is a non-tin surface.
In a preferred embodiment of the present invention, the coating is selected from SiO2Film and Si3N4One of the thin films. Wherein, SiO2The magnetron sputtering coating process parameters of the film are as follows: 120 to 320w, 0.5 to 2.5Pa, O25-15, Ar is 10-30, and the time is 5-15 min;

As shown in fig. 2, the principle of using the ambis profile thickness analyzer to detect the thickness of the plating film on the non-tin surface in step S4 in step S5 is as follows: first, the surface of a float glass sample was scanned using a probe (Stylus) of an Ambios profile film thickness analyzer; then, the probe rotates around an elastic bearing (Pivot) along with the change of the surface flatness of the float glass sample, and the position of a light spot reflected by a reflector (Mirror) changes on a photoelectric Detector (Photo Detector); finally, the voltage value on the photoelectric detector can change along with the position change of the reflected light spot, and the fluctuation change of the surface of the sample can be reproduced through AD conversion. And the thickness of the coating film is the fluctuation of the surface of the float glass sample.
The radius of ions in the chemical solution used for chemical strengthening is smaller than that of ions in the coating film, so that the ions in the chemical solution and the ions in the float glass are prevented from ion exchange, and the ion exchange level of a tin surface is equivalent to that of a non-tin surface.
