Description
Technical field
The present invention relates to a kind of manufacture method of solar base plate glasses with rolling process, belong to glass manufacturing area.
Background technology
Under the overall situation of present international and domestic energy dilemma; exploitation for sun power is reached common understanding socially; the fast development of photovoltaic generation industry, solar water heater have entered huge numbers of families; but it is because lower to solar energy utilization rate; effect is not fine; therefore, improving solar energy utilization ratio from solar water heater and photovoltaic generation all respects, all is very significant.Solar base plate glasses is one of important component part of photovoltaic generation and solar water heater, and therefore, the quality of solar base plate glasses quality will directly influence the height of sun power utilising efficiency.
The common ultra-clear glasses that present known photovoltaic generation and the employed glass of solar water heater substrate generally adopt float glass process or rolling process explained hereafter to come out, the raw material of making this glass generally is quartz sand, soda ash, lime carbonate, aluminium sesquioxide, saltcake, coal dust etc., aluminium sesquioxide is as a kind of oxide compound of introducing in the solar base plate glasses, can increase the thermostability and the chemical stability of glass, a spot of aluminium sesquioxide is a tetrahedral structure in glass, has played the effect of repairing network.But because aluminium sesquioxide can increase the viscosity of glass metal, burn-off rate is slowed down and the settling time prolongation, so the aluminium hydroxide that present many manufacturers have all selected for use fusing point to be lower than aluminium sesquioxide replaces, but because the fusing point of aluminium hydroxide is also than higher, and granularity is thinner, therefore very easily mix inhomogeneous, fusion is insufficient, causes the plate face easily to form brush line and drawing lines, has a strong impact on the quality of solar base plate glasses.
Summary of the invention
The present invention is exactly the defective that exists in the above-mentioned prior art, and a kind of manufacture method of solar base plate glasses with rolling process is provided, and inhomogeneous to solve the mixing that is occurred in the prior art, the plate face easily forms brush line
And the technical barrier of drawing lines, not only reduced melt temperature, to regulate the viscosity of glass, and strengthened the homogeneity of glass, the plate face can not form brush line and drawing lines, has improved the quality of product.
The step that this manufacture method comprises is: 1) select materials, 2) deironing handles, 3) mix, 4) fusing, 5) calendering, 6) annealing.In the described operation of selecting materials, selected raw material comprises quartz sand, soda ash, lime carbonate, antimonous oxide, saltcake, coal dust etc., in addition, has also added nepheline syenite in its raw material.Its raw-material weight proportioning is: quartz sand: 56.7-66.7%, soda ash: 14.6-24.6%, lime carbonate: 11-21%, nepheline syenite: 1-2%, antimonous oxide: saltcake≤0.2%: 1.5-2.5%, coal dust :≤0.06%.
Further, described nepheline syenite, calculate by weight, its material component is: silicon-dioxide: 35-45%, aluminium sesquioxide: 24-34%, sodium oxide: 12-14%, potassium oxide: 5-7%, calcium oxide: 3-6%, magnesium oxide: 0-3.2% burns mistake: 0.6-2%.
Further, described nepheline syenite, calculate by weight, its material component is: aluminium sesquioxide: silicon-dioxide 31.85%: potassium oxide 42.69%: sodium oxide 4.98%: calcium oxide 13.93%: magnesium oxide 5.65%: 0.30%, burn and lose: 0.6%.
Further, described nepheline syenite, calculate by weight, its material component is: aluminium sesquioxide: silicon-dioxide 31.83%: potassium oxide 42.7%: sodium oxide 4.98%: calcium oxide 13.90%: magnesium oxide 5.67%: 0.29%, burn and lose: 0.63%.
Further, described nepheline syenite, calculate by weight, its material component is: aluminium sesquioxide: silicon-dioxide 31.59%: potassium oxide 42.41%: sodium oxide 5.0%: calcium oxide 13.85%: magnesium oxide 5.8%: 0.35%, burn and lose: 1%.
Further, described nepheline syenite, its size range is: 0.125 millimeter≤dn≤0.60 millimeter, dn be 0.125 millimeter account for 15%.
Beneficial effect: 1, because the granularity of nepheline syenite is bigger, and the content of aluminium sesquioxide reaches 24
-34%, the present invention replaces aluminium sesquioxide or aluminium hydroxide by add nepheline syenite in batching, solved that prior art adds aluminium sesquioxide or aluminium hydroxide in batching and the technical barrier that the raw material mixing is inhomogeneous, fusion is insufficient, the plate face easily forms brush line and drawing lines that causes;
2, owing to also contain the compositions of fluxing such as potassium oxide and sodium oxide in the nepheline syenite, reduce the melt temperature of raw material, regulated the viscosity of glass, the corresponding energy consumption that also reduced.The present invention simultaneously utilizes nepheline syenite to replace prior art composition of raw materials alchlor, aluminium hydroxide, and price higher material such as potassium oxide, sodium oxide, calcium oxide, magnesium oxide have also reduced raw materials cost.
