[0002] At present, the existing photovoltaic glass formulations in our country contain SiO 2 、Al 2 o 3 , CaO, MgO, Na 2 O, K 2 O, Sb 2 o 3 , Fe 2 o 3 , SO 3 However, due to the fact that the clarifiers introduced are mainly antimony oxide, etc., the production cost is high, the clarification effect is poor, and there are many defects in the product during production, and the production quality is unstable.
At the same time, the current photovoltaic glass formula Al 2 o 3 , CaO, MgO, Na 2 O composition mismatch, especially Na 2 O+K 2 The high content of O causes a large decrease in the transmittance of photovoltaic glass in a hot and humid environment, and the anti-aging ability of photovoltaic glass in a hot and humid environment is low

The invention discloses an ultra-clear glass formula which is particularly suitable for photovoltaic glass production. The formula comprises SiO2, Na2O, K2O, Al2O3, CaO, MgO, Sb2O3 and SO3, wherein in the formula, the raw material for providing the Sb2O3 is sodium pyroantimonate and the raw material for providing the SO3 is thenardite. The ultra-clear glass formula provided by the invention is low in cost and high in benefit and has the advantages that the problems that glass bubble defect point is large in quantity, photovoltaic or other ultra-clear glass is easy in alkali precipitation under external high-temperature high-humidity environment and the glass transmittance is low in the prior art are solved and the product quality is increased.
Description
technical field [0001] The invention belongs to the technical field of glass composition formulations, in particular to an ultra-clear glass formulation. Background technique [0002] At present, the existing photovoltaic glass formulations in our country contain SiO 2 、Al 2 o 3 , CaO, MgO, Na 2 O, K 2 O, Sb 2 o 3 , Fe 2 o 3 , SO 3 However, since the main clarifying agent introduced into it is antimony oxide, etc., the production cost is high, the clarification effect is poor, and there are many defects in product bubbles and unstable production quality during production. At the same time, the current photovoltaic glass formula Al 2 o 3 , CaO, MgO, Na 2 O composition mismatch, especially Na 2 O+K 2 The high content of O causes a large decrease in the transmittance of photovoltaic glass in a hot and humid environment, and the anti-aging ability of photovoltaic glass in a hot and humid environment is low.
