Problems solved by technology

[0006] 5, because the glass material of prior art is not easy to devitrify, so: the corresponding viscosity temperature that the glass liquid of prior art flows into tin kiln is all set as 10 3 Pa seconds; in the float process technology system of the prior art, the balanced thickness of the glass ribbon is all set at 6.3mm or 6 to 7mm; in the relevant float process system technology of the prior art, it is all defined as the glass ribbon spread Flat viscosity temperature is limited to 10 3.7 Pa sec to 10 4.2 Pa sec
[0007] 6. For most ultra-thin electronic float glass enterprises, the waviness quality of ultra-thin electronic-grade ultra-thin float glass with a thickness of 0.5mm is unstable, and cannot be stabilized at a distance of 20mm. The waviness does not exceed 0.15 microns within the level of
And above-mentioned technical problem has restricted technological development
