Abstract
The invention discloses a kind of fluorin environment protection glass, the allocation ratio of this glass formula is by weight: quartz sand: 27 ~ 32 parts; Selenium powder: 0.0008 ~ 0.0011 part; Calcite: 7 ~ 8 parts; Glass cullet: 48 ~ 55 parts; Aluminum oxide: 0.7 ~ 0.9 part; Sodium sulfate anhydrous.min(99): 2 ~ 3 parts; Soda ash: 9 ~ 10 parts.Through practice, the glassware produced realizes floride-free residue on the basis of conventional glass, and eliminates food safety hidden danger.Traditional glass raw materials cost is 60 yuan/100kg, and frit cost of the present invention is 52 yuan/100kg, has larger economic benefit.
Description
Technical field
The present invention relates to a kind of glass formula, particularly a kind of glass formula of the floride-free safety and environmental protection for the manufacture of glassware.
Background technology
In traditional glass formula, containing fluorite and white arsenic two kinds of raw materials, fluorite, also known as fluorite, adds as fusing assistant, opalizer, and it can promote the fusing of frit.White arsenic is commonly called as arsenic, also known as arsenic in a natural state, makes finings and discoloring agent, with reinforcing glass goods light transmission.
1, containing fluorite in formula, the glassware produced has fluorine residue, and produces fluoride pollution to content.
2, containing white arsenic in formula, in formula error and furnace failure, the glassware produced has severe toxicity, has great food safety hidden danger.
Summary of the invention
Instant invention overcomes above-mentioned the deficiencies in the prior art, eliminate fluorite, white arsenic two kinds of objectionable impuritiess, provide a kind of glass formula of the floride-free safety and environmental protection for the manufacture of glassware.
Technical scheme of the present invention is achieved in that
A kind of fluorin environment protection glass, the allocation ratio of this glass formula is by weight:
Selenium powder, as finings and discoloring agent, increases the light transmission of glass; Sodium sulfate anhydrous.min(99), as solubility promoter and finings, promotes the fusing of frit; Glass cullet account for 48 ~ 55 parts, make that smelting furnace is temperature required can be down to 1550 ± 50 degree, thus reach minimizing fuel, and improve the recovery utilization rate of glass, two aspects reach the object reduced costs with environmental protection.
As preferably, soda ash composition comprises sodium carbonate, ferric oxide, and the ratio of sodium carbonate is more than 98%, and the ratio of ferric oxide is less than 0.02%.Do main raw material and sodium ion is provided.
As preferably, aluminum oxide composition comprises aluminium sesquioxide, ferric oxide, and the ratio of aluminium sesquioxide is for being greater than 96%, and the ratio of ferric oxide is less than 0.05%.The tendency towards devitrification of glass can be reduced, increase the intensity of glass, improve the processability of glass.
As preferably, calcite composition comprises calcium oxide, ferric oxide, and the ratio of calcium oxide is more than 55%, and the ratio of ferric oxide is less than 0.02%.The viscosity of glass can be reduced, accelerate fusing and the clarification of glass.
As preferably, quartz sand composition comprises silicon-dioxide, ferric oxide and water, and the ratio of silicon-dioxide is more than 99%, and the ratio of ferric oxide is less than 0.02%, and the ratio of water is less than 0.8%.For glass provides silica component.
Have employed the invention has the beneficial effects as follows of technique scheme:
Through practice, the glassware produced realizes floride-free residue on the basis of conventional glass, and eliminates food safety hidden danger.Traditional glass raw materials cost is 60 yuan/100kg, and frit cost of the present invention is 52 yuan/100kg, has larger economic benefit.
Embodiment
The specific embodiment of the present invention is as follows:
Embodiment: a kind of fluorin environment protection glass, the allocation ratio of this glass formula is by weight:
Glass cullet account for 50.36kg, make that smelting furnace is temperature required can be down to 1550 ± 50 degree, thus reach minimizing fuel, and improve the recovery utilization rate of glass, two aspects reach the object reduced costs with environmental protection.Selenium powder, as finings and discoloring agent, increases the light transmission of glass; Sodium sulfate anhydrous.min(99), as solubility promoter and finings, promotes the fusing of frit.
