Abstract
The invention discloses a fluoride-free environment-friendly glass formula which comprises the following components in parts by weight: 27-32 parts of quartz sand, 0.0008-0.0011 part of selenium powder, 7-8 parts of calcites, 48-55 parts of cullet, 0.7-0.9 part of aluminum oxide, 2-3 parts of anhydrous sodium sulphate and 9-10 parts of sodium carbonate. Practices prove that a produced glass vessel realizes the fluoride-free residues on the basis of the traditional glass vessel and eliminates the potential safety hazards of foods. The raw material cost of the traditional glass is ** yuan/100 kg, the raw material cost of the glass disclosed by the invention is ** yuan/100 kg, so that the glass disclosed by the invention has higher 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 the traditional glass prescription, contain two kinds of raw materials of fluorite and white arsenic, fluorite claims fluorite again, adds as fusing assistant, opalizer, it can promote the fusing of frit.White arsenic is commonly called as arsenic, claims arsenic in a natural state again, makes finings and discoloring agent, with reinforcing glass goods light transmission.
1, contain fluorite in the prescription, the glassware of producing has fluorine residue, and content is produced fluoride pollution.
2, contain white arsenic in the prescription, in prescription error and furnace failure, the glassware of producing has severe toxicity, and great food safety hidden danger is arranged.
Summary of the invention
The present invention has overcome above-mentioned the deficiencies in the prior art, has removed fluorite, two kinds of objectionable impuritiess of white arsenic, and a kind of glass formula of the floride-free safety and environmental protection for the manufacture of glassware is provided.
Technical scheme of the present invention is achieved in that
A kind of fluorin environment protection glass formula, 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.
Selenium powder increases the light transmission of glass as finings and discoloring agent; Sodium sulfate anhydrous.min(99) promotes the fusing of frit as solubility promoter and finings; Glass cullet account for 48～55 parts, make that smelting furnace is temperature required can be down to 1550 ± 50 degree, thereby reach minimizing fuel, improve the recovery utilization rate of glass, and two aspects reach and reduce cost and the purpose of environmental protection.
As preferably, comprise yellow soda ash, ferric oxide in the soda ash composition, the ratio of yellow soda ash is more than 98%, the ratio of ferric oxide is below 0.02%.Do main raw material sodium ion is provided.
As preferably, comprise aluminium sesquioxide, ferric oxide in the aluminum oxide composition, the ratio of aluminium sesquioxide is greater than 96%, the ratio of ferric oxide is less than 0.05%.Can reduce the tendency towards devitrification of glass, increase glass intensity, improve the processability of glass.
As preferably, comprise calcium oxide, ferric oxide in the calcite composition, the ratio of calcium oxide is more than 55%, the ratio of ferric oxide is below 0.02%.The viscosity of glass be can reduce, fusing and the clarification of glass accelerated.
As preferably, comprise silicon-dioxide, ferric oxide and water in the quartz sand composition, the ratio of silicon-dioxide is more than 99%, and the ratio of ferric oxide is below 0.02%, and the ratio of water is below 0.8%.For glass provides silica component.
Adopted the invention has the beneficial effects as follows of technique scheme:
Through practice, the glassware of producing is realized floride-free residue on the basis of traditional glass vessel, and eliminates food safety hidden danger.The traditional glass raw materials cost is 60 yuan/100kg, and frit cost of the present invention is 52 yuan/100kg, has bigger economic benefit.
Embodiment
The specific embodiment of the present invention is as follows:
Embodiment: a kind of fluorin environment protection glass formula, the allocation ratio of this glass formula is by weight:
Quartz sand: 29.616kg selenium powder: 0.8-1.1g
Calcite: 7.77kg glass cullet: 50.36kg
Aluminum oxide: 0.813kg Sodium sulfate anhydrous.min(99): 2.229kg
Soda ash: 9.567kg.
Glass cullet account for 50.36kg, make that smelting furnace is temperature required can be down to 1550 ± 50 degree, thereby reach minimizing fuel, improve the recovery utilization rate of glass, and two aspects reach and reduce cost and the purpose of environmental protection.Selenium powder increases the light transmission of glass as finings and discoloring agent; Sodium sulfate anhydrous.min(99) promotes the fusing of frit as solubility promoter and finings.
