Abstract

The invention relates to the technical field of float glass, and particularly discloses high-light-transmittance high-heat-insulation energy-saving float glass and a production process thereof. The high-light-transmittance high-heat-insulation energy-saving float glass is mainly prepared from the following raw materials in parts by weight: 60 to 75 parts of silica sand, 15 to 20 parts of sodium oxide, 3 to 5 parts of magnesium oxide, 16 to 18 parts of limestone, 2.5 to 7.5 parts of feldspar, 0.04 to 0.06 part of ferric oxide, 0.2 to 1.5 parts of a reducing agent and 0.1 to 0.35 part of an absorbent. The reducing agent is at least one of stannous chloride and carbon powder, and the absorbent is indium tin oxide. The high-light-transmittance, high-heat-insulation energy-saving float glass has the advantages of high light transmittance and high heat insulation.

Description

technical field [0001] This application relates to the technical field of float glass, more specifically, it relates to a float glass with high light transmission, high heat insulation and energy saving and its production process. Background technique [0002] With the continuous accumulation of economic technology, the production process of float glass has been greatly improved and improved. At present, the improvement direction of float glass production process includes raw material ratio, melting process, molding process, energy saving and environmental protection process, etc. The heat insulation performance of the existing float glass original sheet is poor, the visible light transmittance and the heat insulation effect rise and fall at the same time, it is impossible to make a choice of light, and the heat insulation performance also decays with the passage of time, so It is an important task at present to develop new HTI float glass with better quality and suitable f...
