A kind of photovoltaic glassTechnical field
The present invention relates to field of glass production technology, in particular to a kind of photovoltaic glass.
Background technology
Along with country's adjustment to novel energy industrial policy, the clean energy resource such as solar energy increasingly comes into one's own, applicationMore and more extensive.The most increasing high building uses solar energy to provide electric power, and photovoltaic glass obtains widely the most therewithApplication, but present photovoltaic glass is relatively low due to light transmittance, causes solar energy utilization ratio relatively low, accordingly, it would be desirable to change photovoltaicThe formula of glass, improves light transmittance and combination property thereof.
Summary of the invention
Present invention aim at solving the problems referred to above, it is provided that a kind of photovoltaic glass.
For achieving the above object, the invention provides a kind of photovoltaic glass, by forming according to the raw material of weight portion as follows: twoSilicon oxide 52 ~ 68 parts, cullet 30 ~ 45 parts, aluminium sesquioxide 12 ~ 26 parts, calcium oxide 14 ~ 24 parts, phosphorus pentoxide 2 ~ 10 parts,Magnesium oxide 2 ~ 6 parts, potassium oxide 4 ~ 8 parts, sodium oxide 3 ~ 11 parts, Borax 1 ~ 5 part, zinc oxide 1 ~ 3 part, 2 ~ 4 parts of barium sulfate, selenium powder0.1 ~ 0.5 part and stabilizer 2 ~ 6 parts.
Described photovoltaic glass, by forming according to the raw material of weight portion as follows: silicon dioxide 55 ~ 65 parts, cullet 35 ~ 42Part, aluminium sesquioxide 14 ~ 23 parts, calcium oxide 15 ~ 20 parts, phosphorus pentoxide 4 ~ 7 parts, magnesium oxide 3 ~ 5 parts, potassium oxide 5 ~ 8 parts, oxygenChange 4 ~ 6 parts of sodium, Borax 1 ~ 2.4 part, zinc oxide 1 ~ 1.6 part, 2 ~ 2.6 parts of barium sulfate, selenium powder 0.1 ~ 0.3 part and stabilizer 3 ~ 5 parts.
Described photovoltaic glass, by forming according to the raw material of weight portion as follows: silicon dioxide 60 parts, cullet 36 parts, three oxygenChange 15 parts of two aluminum, calcium oxide 18 parts, phosphorus pentoxide 6 parts, magnesium oxide 3.6 parts, potassium oxide 6 parts, sodium oxide 4.8 parts, Borax 1.6Part, zinc oxide 1.2 parts, 2.5 parts of barium sulfate, selenium powder 0.15 part and stabilizer 4 parts.
Beneficial effects of the present invention: this kind of photovoltaic glass strength height, has good light transmission and decay resistance, toolHaving higher degree of purity and brightness, production cost is low, and service life is long, can be effectively improved the utilization rate to solar energy.
Detailed description of the invention
The present invention takes techniques below scheme to realize: this kind of photovoltaic glass, by forming according to the raw material of weight portion as follows:Silicon dioxide 52 ~ 68 parts, cullet 30 ~ 45 parts, aluminium sesquioxide 12 ~ 26 parts, calcium oxide 14 ~ 24 parts, phosphorus pentoxide 2 ~ 10Part, magnesium oxide 2 ~ 6 parts, potassium oxide 4 ~ 8 parts, sodium oxide 3 ~ 11 parts, Borax 1 ~ 5 part, zinc oxide 1 ~ 3 part, 2 ~ 4 parts of barium sulfate, selenium0.1 ~ 0.5 part of powder and stabilizer 2 ~ 6 parts.
As the preferred version of the present invention, photovoltaic glass is by forming according to the raw material of weight portion as follows: silicon dioxide 55 ~ 65Part, cullet 35 ~ 42 parts, aluminium sesquioxide 14 ~ 23 parts, calcium oxide 15 ~ 20 parts, phosphorus pentoxide 4 ~ 7 parts, magnesium oxide 3 ~ 5 parts,Potassium oxide 5 ~ 8 parts, sodium oxide 4 ~ 6 parts, Borax 1 ~ 2.4 part, zinc oxide 1 ~ 1.6 part, 2 ~ 2.6 parts of barium sulfate, selenium powder 0.1 ~ 0.3 partWith stabilizer 3 ~ 5 parts.
As the preferred version of the present invention, photovoltaic glass is by forming according to the raw material of weight portion as follows: silicon dioxide 60 parts,Cullet 36 parts, aluminium sesquioxide 15 parts, calcium oxide 18 parts, phosphorus pentoxide 6 parts, magnesium oxide 3.6 parts, potassium oxide 6 parts, oxidation4.8 parts of sodium, Borax 1.6 parts, zinc oxide 1.2 parts, 2.5 parts of barium sulfate, selenium powder 0.15 part and stabilizer 4 parts.
This kind of photovoltaic glass strength height, has good light transmission and decay resistance, have higher degree of purity andBrightness, production cost is low, and service life is long, can be effectively improved the utilization rate to solar energy.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art withoutNeed creative work just can make many modifications and variations according to the design of the present invention.Therefore, all technology in the artPersonnel are available by logical analysis, reasoning, or a limited experiment the most on the basis of existing technologyTechnical scheme, all should be in the protection domain being defined in the patent claims.
