Abstract

The invention discloses ultra white thin electronic glass and a production method thereof, the ultra white thin electronic glass is made by a float glass production technology, the thickness is 1.5-3.2mm, the visible light transmittance is 91.3-91.8%, bubble density is 0.1-0.32 / m<2>, raw materials comprises a base component, a clarifying agent and a decoloring agent, the base component comprises 71.0-72.0 parts by weight of SiO2, 12-15 parts by weigh of Na2O+K2O, 8.5-10.5 parts by weigh of CaO, 1.5-3 parts by weigh of MgO, 0.2-0.8 part by weigh of Al2O3 and 0.01-0.015 part by weigh of Fe2O3, the clarifying agent comprises CeO2 and KNO3, the weight of the KNO3 is 11-15% of the total amount of Na2O +K2O, the weight of the CeO2 is 0.32-0.45% of the total weight of the base component, the KNO3 and the decoloring agent, the decoloring agent is Co2O3, and the dosage of the decoloring agent is 0.000005 to 0.00004 part by weight. The clarification process of the ultra white and thin electronic glass can be controlled by combination of the clarifying agent, glass liquid viscosity and the melting process atmosphere, and bubbles of the ultra white thin electronic glass can be reduced.

Description

technical field [0001] The invention relates to the technical field of glass production, and specifically relates to an ultra-white and thin electronic glass and a production method thereof. Background technique [0002] The development of electronic technology has led to an increase in the demand for ultra-thin glass, and high profits have driven glass manufacturers to research the production technology of ultra-thin glass. In the prior art, there are three methods that can be used to produce ultra-thin glass, namely: overflow down-draw method; float method and narrow-slot down-draw method. Due to the huge market demand, foreign glass production giants hold in their hands the production technology of ultra-thin float glass capable of mass production, carry out technical blockade, and only sell products but not technology. Most of my country's ultra-thin glass is imported, resulting in high product prices, and it is difficult to break through the production technology of ul...
