Abstract

The invention relates to the field of glass making and in particular relates to super-white and super-thick float glass and a preparation method thereof. A raw material formula of the super-white and super-thick float glass is designed, an edge roller control technology is adopted, from a first pair of edge controllers to the last pair of edge controllers, an inward component force produced by virtue of speed difference and negative angle of each pair of edge rollers is utilized for controlling the speed difference to be 15-50m / h; runner temperature is controlled to be (1100-1105)+ / -1 DEG C; molten tin slot outlet temperature is controlled to be 625+ / -5 DEG C; pulling amount of each edge roller is controlled to be 560-610t / d, plate width is controlled to be 4000-4100mm, inner teeth are 3580-3860mm wide, and Vmain is 135-165m / h; and the prepared glass is good in transmittance, high in whiteness, small in colour difference, ultraviolet-resistant and non-glare. Optical distortion angle is more than 55 degrees, the produced glass plate is wide, and thickness and inner teeth are stable.

Description

technical field [0001] The invention relates to the field of glass manufacturing, in particular to an ultra-white and ultra-thick float glass and a production and preparation method thereof. Background technique [0002] With the sharp reduction of non-renewable energy sources on the earth, the energy crisis situation is becoming increasingly severe, and the development of new energy sources has long been a global issue. In such an era background, the solar photovoltaic industry has received more and more attention from people. As a substrate material in the solar photovoltaic industry, ultra-clear glass greatly improves the photoelectric conversion efficiency with its unique high light transmittance, and provides a broader development space for the development of solar technology. [0003] In the past, ultra-clear glass was mostly produced by small-tonnage ultra-clear rolling lines, and with the substantial increase in market demand for ultra-clear glass, large-tonnage ult...
