Abstract
The invention discloses arsenic-free tempered glass and a preparation method thereof. The arsenic-free tempered glass is prepared from raw materials in parts by weight as follows: 50 parts of quartz sand, 6-18 parts of lithium feldspar, 10-15 parts of coal gangue, 5-8 parts of aluminum oxide, 13-16 parts of calcite, 8-12 parts of dolomite, 1-3 parts of sodium nitrate, 1-2 parts of fluorite, 2-2.5 parts of sodium fluorosilicate, 10-15 parts of sodium carbonate, 0.7 parts of sodium sulfate, 0.5 parts of calcium sulfate, 0.4 parts of cerium oxide and 0.2-0.4 parts of a decolorizing agent. The arsenic-free tempered glass has the arsenic content far lower than allowable dissolution amount specified by the nation, has no toxic or side effects on human bodies and causes no environmental pollution; at the same melting temperature, the clarification time is a half of that spent by using arsenic-antimony oxides, and the production efficiency is high.
Description
Technical field
The present invention relates to glass, and in particular to tempering Arsenic-free glass and preparation method thereof.
Background technology
Glass technology is a traditional industry, due to a series of premium properties that glass itself has so as to apply
Extremely extensively, almost throughout people's production and the various aspects lived.But the production in glass, process and use process
In, will also result in some negative effects.Such as in the production of existing glass, due to using harmful arsenic, antimony thing
Matter, easily works the mischief to human body.
Arsenic and antimony are respectively with As2O3、Sb2O3Form be widely present in various glass, as clarifier, play elimination
The effect of bubble.When with arsenic oxide as clarifier, low temperature As2O3Absorb NaNO3The oxygen for decomposing to give off becomes As2O5,
As2O5Decompose to give off oxygen during high temperature again, oxygen is entered in bubble, bubble volume is increased and is discharged from glass, i.e.,：
As when 600-1200 DEG C2O3 + O2 → As2O5
As when more than 1300 DEG C2O5 → As2O3 + O2
In general, the arsenic sb oxide in glass is worked the mischief by two approach to human and environment, and one is in glass
In melting process, in high temperature environments, a part can volatilize to form gas, and the gas for being formed that volatilizees enters air with flue gas, right
Air is polluted；One is that part arsenic sb oxide has been stayed in glass, progressively dissolution in use, so as to harmful to human
Health.
Due to stripping quantity of the arsenic sb oxide in vitreous body it is relatively low, so the harm to people is not it is obvious that long-term
Since do not cause the attention of people, but their harm to human body are objective reality.Now with the health meaning of people
Knowledge is stepped up with environmental consciousness, and the idea of environmental protection is gradually rooted in the hearts of the people, 2005, joint country of State General Administration for Quality Supervision
Standard management committee has formulated the dissolutions such as relevant glass container arsenic, antimony that the relevant packagings for foodstuff of GB19778-2005 are used jointly
The mandatory standard of amount.
Arsenic antimony content in order to control packaging for foodstuff glass, typically takes two kinds of methods, and one is not use the original containing arsenic antimony
Material, only by improving fusion temperature, extends settling time to be produced, and this method not only greatly improves power consumption, increases production
Cost, and yield can be reduced；Another kind of method is according to the toxicity of the stibium oxide characteristic lower than the toxicity of arsenic oxide arsenoxide, to increase
Replacing arsenic oxide arsenoxide, so as to reach the purpose of low arsenic, but this glass is not truly without arsenic to stibium oxide consumption
Glass, although and stibium oxide toxicity it is low, its toxicity still can not be ignored.Up to this point, make in packaging for foodstuff
Glass container aspect, to the never control well of arsenic antimony stripping quantity, is extremely difficult to state specified standards.
The content of the invention
The present invention be in order to solve existing glass in because arsenic, antimony stripping quantity are higher, be unfavorable for health and environmental protection,
The problem of state-set standard can not be reached, and provides a kind of tempering Arsenic-free glass and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of tempering Arsenic-free glass, is to be divided into raw material preparation by each group including following weight portion：
The lithium Anhydrite 6-18 of quartz sand 50
Gangue 10-15 aluminium sesquioxide 5-8
Calcite 13-16 dolomites 8-12
The fluorite of sodium nitrate 1-3 1-2
The soda of prodan 2-2.5 10-15
The calcium sulfate 0.5 of sodium sulfate 0.7
The decolorising agent 0.2-0.4 of cerium oxide 0.4.
Further, a kind of steel tempering Arsenic-free glass, is to be divided into raw material preparation by each group including following weight portion：
The lithium Anhydrite 12 of quartz sand 50
The aluminium sesquioxide 6 of gangue 12
The dolomite 10 of calcite 15
The fluorite 1 of sodium nitrate 2
The soda 12 of prodan 2
The calcium sulfate 0.5 of sodium sulfate 0.7
The decolorising agent 0.3 of cerium oxide 0.4.
The preparation method of above-mentioned tempering Arsenic-free glass, step is：
（1）By above-mentioned each component crush after mixed melting, shape to obtain glass substrate；
（2）Glass substrate is put into 440 DEG C~450 DEG C softenings of heating, instantaneous pressure air chilling is then carried out in reinforcing device
Process, then cool down, obtain final product.
In process of production, sodium sulfate, calcium sulfate and cerium oxide are used in mixed way, and as clarifier, replace original arsenic antimony oxygen
Compound.First it is calcium sulfate, at 1300-1400 DEG C, following decomposition reaction occurs：
CaSO4 → CaO + SO3
SO3 → SO2 + O2
The oxygen for now producing enters bubble so that bubble volume increases, and is then discharged out；
At 1400-1460 DEG C, as clarifier, there is following decomposition reaction in sodium sulfate and cerium oxide collective effect：
Na2SO4 → Na2O + SO3
SO3 → SO2 + O2
CeO2 → CeO+ O2
The oxygen for now producing enters bubble so that bubble volume increases, and further discharges the bubble under high temperature in glass, plays
The purpose of clarification.
Just above-mentioned each component crush after mixed melting, shape to obtain glass substrate, then heat 440 DEG C~450 DEG C softenings,
Then instantaneous pressure air chilling process is carried out in reinforcing device, is then cooled down, obtain safety glass
GB19778-2005 packaging glass container lead, cadmium, arsenic, antimony amount of dissolution regulation, the amount of dissolution of arsenic is 0.2ppm,
The glass that will be produced according to component of the present invention, with 4% acetic acid solution（Volume fraction）22+2Immersion 24 is little under conditions of DEG C
When after detect, the stripping quantity of arsenic is only between 0.002-0.003PPm, to comply fully with state specified standards.
Compared with prior art, the present invention has advantages below：
（1）Arsenic content of the present invention well below national regulation amount of dissolution, it is without any side effects to human body, will not produce
Environmental pollution；
（2）The present invention under same fusion temperature, settling time shorten to using the time used by arsenic sb oxide two/
One, production capacity improves 10% or so.
（3）Arsenic-free glass bottle compositional selecting of the present invention is reasonable, proportioning is accurate, does not use arsenic sb oxide, but can reach with
The same quality standard of the glass of making clarifier using arsenic sb oxide, in the wavelength of 500-650nm, glass of the present invention it is saturating
Light rate is more than 97%.
（4）The production cost of the glass unit product for making clarifier with existing use arsenic sb oxide of the invention does not increase
Plus, with very big market potential.
