Abstract
The invention discloses a kind of arsenic-free glass bottles, it is to solve in existing food packaging glass since arsenic, antimony stripping quantity are higher, it is unfavorable for health and environmental protection, it is impossible to which the problem of reaching state-set standard is to be divided into prepared by raw material by each group for including following parts by weight：Quartz sand 51 63, lithium (or sodium, potassium) feldspar 39, calcite 12 19, dolomite 0 20, sodium nitrate 13, fluorite 0 2.2, prodan 03, soda ash 15 21, sodium sulphate 0.1 0.5, calcium sulfate 0.3 1, cerium oxide 0.1 0.5.Above-mentioned each component is uniformly mixed, according to existing vial manufacturing method, through mixing, melted, shaping, is annealed to get a kind of arsenic-free glass bottle.Arsenic content of the present invention is far below the amount of dissolution of national regulation, has no toxic and side effect to human body, and generation environment does not pollute；Under same fusion temperature, settling time shortens to the half using the time used in arsenic sb oxide, and production capacity improves 10% or so.
Description
Technical field
The present invention relates to a kind of Arsenic-free glass vessel, and in particular to a kind of arsenic-free glass bottle.
Background technology
Glass technology is a traditional industry, due to a series of glass possessed excellent performances in itself, makes its application
Extremely extensively, the various aspects for almost producing and living throughout people.However the production in glass, processing and use process
In, it will also result in some negative effects.Such as in the production of existing glass, due to the use of harmful arsenic, antimony object
Matter, easy do harm to huamn body.
Arsenic and antimony are widely present in the form of As2O3, Sb2O3 respectively in various glass, as fining agent, play elimination
The effect of bubble.When by the use of arsenic oxide as fining agent, low temperature As2O3 absorbs the oxygen that NaNO3 is decomposed to give off and becomes
Oxygen is decomposed to give off when As2O5, As2O5 high temperature again, oxygen enters in bubble, and bubble volume is made to increase and be discharged from glass,
I.e.：
As2O3+O2 → As2O5 at 600-1200 DEG C
As2O5 → As2O3+O2 at 1300 DEG C or more
In general, the arsenic sb oxide in glass damages to human and environment by two approach, first, in glass
In melting process, in high temperature environments, a part can volatilize to form gas, and the gas for formation of volatilizing enters air with flue gas, right
Air pollutes；It first, part arsenic sb oxide has been stayed in glass, progressively dissolves out in use, so as to harmful to human
Health.
Since stripping quantity of the arsenic sb oxide in vitreum is relatively low, so not being it is obvious that long-term to the harm of people
Since do not attract people's attention, however they are objective reality to the harm of human body.It anticipates now with people's health
Knowledge is stepped up with environmental consciousness, and environmentally protective idea 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 the related glass container arsenic that the related food packagings of GB19778-2005 use, antimony jointly
The mandatory standard of amount.
In order to control arsenic antimony content in food packaging glass, two kinds of methods are generally taken, first, the original without using the antimony containing arsenic
Material only by improving fusion temperature, extends settling time to be produced, this method not only greatly improves energy consumption, increases production
Cost, and yield can be reduced；Another method is the characteristic lower than the toxicity of arsenic oxide arsenoxide according to the toxicity of antimony oxide, to increase
Antimony oxide dosage replaces arsenic oxide arsenoxide, and so as to achieve the purpose that low arsenic, but this glass is not truly without arsenic
Glass, and although the toxicity of antimony oxide is low, toxicity cannot still be ignored.Up to this point, make in food packaging
In terms of glass container, to the never control well of arsenic antimony stripping quantity, state specified standards is extremely difficult to.
The content of the invention
The present invention is to solve to be unfavorable for human body since arsenic, antimony stripping quantity are higher in existing food packaging glass and be good for
Health and environmental protection, it is impossible to the problem of reaching state-set standard, and provide a kind of arsenic-free glass bottle.
The present invention is achieved by the following technical solutions：
A kind of arsenic-free glass bottle is to be divided into prepared by raw material by each group for including following parts by weight：
Quartz sand 51-63 lithiums (or sodium, potassium) feldspar 3-9
Calcite 12-19 dolomites 0-20
Sodium nitrate 1-3 fluorites 0-2.2
Prodan 0-3 soda ash 15-21
Sodium sulphate 0.1-0.5 calcium sulfate 0.3-1
Cerium oxide 0.1-0.5.
Above-mentioned each component is uniformly mixed, according to existing vial manufacturing method, through mixing, melted, shaping, is annealed, i.e.,
Obtain a kind of arsenic-free glass bottle.
Further, a kind of arsenic-free glass bottle is to be divided into prepared by raw material by each group for including following parts by weight：
Quartz sand 56-58 lithiums feldspar 5.1
14 dolomite 2.7 of calcite
Sodium nitrate 1.6-2.2 fluorites 0.6-1.2
Soda ash 16-19 sodium sulphate 0.1-0.3
Calcium sulfate 0.4-0.7 cerium oxide 0.15-0.4.
Further, decolorising agent can also be added in the raw material.
In process of production, sodium sulphate, calcium sulfate and cerium oxide are used in mixed way, as fining agent, instead of original arsenic antimony oxygen
Compound.It is calcium sulfate first, at 1300-1400 DEG C, following decomposition reaction occurs：
CaSO4→CaO+SO3
SO3→SO2+O2
The oxygen generated at this time enters bubble so that bubble volume increases, and is then discharged out；
At 1400-1460 DEG C, as fining agent, following decomposition reaction occurs for sodium sulphate and cerium oxide collective effect：
Na2SO4→Na2O+SO3
SO3→SO2+O2
CeO2→CeO+O2
The oxygen generated at this time enters bubble so that bubble volume increases, and further discharges the bubble under high temperature in glass, plays
Clear purpose.
GB19778-2005 packaging glass containers lead, cadmium, arsenic, antimony amount of dissolution regulation, the amount of dissolution of arsenic are
0.2ppm, the glass that will be produced according to component of the present invention, with 4% acetic acid solution (volume fraction) under conditions of 22+2 DEG C
Impregnate 24 it is small when after detect, the stripping quantity of arsenic is only between 0.002-0.004PPm, complies fully with state specified standards.
Compared with prior art, the present invention has the following advantages：
(1) a kind of arsenic-free glass bottle of the present invention, arsenic content well below national regulation amount of dissolution, to human body without appointing
What toxic side effect, will not generation environment pollution；
(2) a kind of arsenic-free glass bottle of the present invention, under same fusion temperature, settling time is shortened to using arsenic sb oxide
The half of time used, production capacity improve 10% or so.
(3) a kind of arsenic-free glass bottle compositional selecting of the present invention rationally, proportioning it is accurate, without using arsenic sb oxide,
But it can reach the same quality standard of glass with making fining agent using arsenic sb oxide, in the wavelength of 500-650nm, this hair
The light transmittance of bright glass is more than 97%.
(4) present invention and the production cost of the existing glass unit product for being made fining agent using arsenic sb oxide are not increased
Add, there is very big market potential.
