Abstract
The invention discloses an arsenic-free glass bottle which aims to solve the problem that the traditional food packaging glass is bad for human body health and environmental protection and can not reach the national specified standard due to higher arsenic and antimony dissolving amount. The arsenic-free glass bottle comprises the following all components in parts by weight: 100 parts of quartz sand, 6-18 parts of lithium (or sodium and potassium) feldspar, 24-38 parts of calcite, 0-40 parts of dolomite, 2-6 parts of sodium nitrate, 0-4.4 parts of fluorite, 0-6 parts of sodium fluosilicate, 30-40 parts of soda ash, 0.6-0.8 part of sodium sulfate, 1.3-1.7 parts of calcium sulfate and 0.6-0.8 part of cerium oxide. All the components are uniformly mixed, melted, formed and annealed according to the traditional glass bottle manufacture method to obtain the arsenic-free glass bottle. The invention has arsenic content which is far lower than national specified dissolving tolerance, no toxic or side effect on a human body and no environmental pollution; and at the same melting temperature, clarifying time is shortened to a half of the time used by using arsenic antimony oxide, and the production capacity is improved by 10 percent or so.
Description
Technical field
The present invention relates to a kind of Arsenic-free glass vessel, be specifically related to a kind of arsenic-free glass bottle.
Background technology
Glasswork is a traditional industry, because a series of premium propertiess that glass itself is had make its application extremely extensive, has almost spreaded all over all respects that people produce and live.Yet in production, processing and the use of glass, also can cause some negative effects.Such as in the production of existing glass,, easily human body is worked the mischief owing to use harmful arsenic, antimony material.
Arsenic and antimony are respectively with As

In general, the arsenic sb oxide in the glass comes human and environment is worked the mischief by two approach, and the one, founding in the process of glass, under hot environment, a part can volatilization form gas, and the gas that volatilization forms enters atmosphere with flue gas, and atmosphere is polluted; The one, part arsenic sb oxide has been stayed in the glass, progressively stripping in use, thereby the health of harmful to human.
Because the stripping quantity of arsenic sb oxide in vitreum be lower, so be not clearly, do not cause people's attention for a long time, yet they are outwardness to the harm of human body to people's harm.Now along with people's the health perception and the progressively raising of environmental consciousness, the idea of environmental protection is rooted in the hearts of the people gradually, 2005, State General Administration for Quality Supervision united the compulsory standard that national standard management committee has formulated stripping quantities such as the relevant Glass Containers arsenic that GB19778-2005 related food packing is used, antimony jointly.
In order to control arsenic antimony content in the food product pack glass, generally take two kinds of ways, the one, do not use the raw material that contains arsenic antimony, only depend on the raising temperature of fusion, prolong settling time and produce, this method not only significantly improves power consumption, increase production cost, and can reduce output; Another kind method is according to the toxicity of the weisspiessglanz characteristic lower than the toxicity of arsenic oxide arsenoxide, replace arsenic oxide arsenoxide to increase the weisspiessglanz consumption, thereby reach the purpose of low arsenic, but this glass is not Arsenic-free glass truly, although the toxicity of weisspiessglanz is low, its toxicity still can not be ignored.Up to this point, aspect the Glass Containers of food product pack use, arsenic antimony stripping quantity is never had better controlled, be difficult to reach state specified standards.
Summary of the invention
The present invention is in order to solve in the existing food product pack glass because arsenic, antimony stripping quantity than higher, are unfavorable for HUMAN HEALTH and environmental protection, can not reach the problem of state-set standard, and a kind of arsenic-free glass bottle is provided.
The present invention is achieved by the following technical solutions:
A kind of arsenic-free glass bottle is to be feedstock production by each component of comprising following weight part:
Quartz sand 100 lithiums (or sodium, potassium) feldspar 6-18
Calcite 24-38 rhombspar 0-40
SODIUMNITRATE 2-6 fluorite 0-4.4
Sodium Silicofluoride 0-6 soda ash 30-40
Sodium sulfate 0.6-0.8 calcium sulfate 1.3-1.7
Cerium oxide 0.6-0.8.
Above-mentioned each component is mixed,, through mixing, found, be shaped, anneal, promptly get a kind of arsenic-free glass bottle according to existing vial manufacture method.
Further, a kind of arsenic-free glass bottle is to be feedstock production by each component of comprising following weight part:
Quartz sand 100 lithium feldspars 12
Calcite 28 rhombspars 20
SODIUMNITRATE 3-5 fluorite 0.6-3
Soda ash 32-38 sodium sulfate 0.6-0.7
Calcium sulfate 1.4-1.6 cerium oxide 0.6-0.7.
Further, also contain discoloring agent in the described raw material.
In process of production, sodium sulfate, calcium sulfate and cerium oxide mix use, as finings, replace original arsenic sb oxide.At first be calcium sulfate, in the time of 1300-1400 ℃, following decomposition reaction take place:
CaSO
4→CaO+SO
3
SO
3→SO
2+O
2
The oxygen that produce this moment enters bubble, makes bubble volume increase, and discharges then;
In the time of 1400-1460 ℃, following decomposition reaction, as finings, take place in sodium sulfate and cerium oxide acting in conjunction:
Na
2SO
4→Na
2O+SO
3
SO
3→SO
2+O
2
CeO
2→CeO+O
2
The oxygen that produce this moment enters bubble, makes bubble volume increase, and further discharges the bubble in the high temperature lower-glass, plays clarifying purpose.
GB19778-2005 packing Glass Containers lead, cadmium, arsenic, antimony amount of dissolution regulation, the amount of dissolution of arsenic is 0.2ppm, will be according to the glass of component production of the present invention, detect after soaking 24 hours under 22 ± 2 ℃ the condition with 4% acetic acid solution (volume fraction), the stripping quantity of arsenic only is between the 0.002-0.004ppm, to meet state specified standards fully.
Compared with prior art, the present invention has the following advantages:
(1) a kind of arsenic-free glass bottle of the present invention, its arsenic content is well below the amount of dissolution of national regulation, and is without any side effects to human body, can not produce environmental pollution;
(2) a kind of arsenic-free glass bottle of the present invention, under same temperature of fusion, settling time shortens to and uses 1/2nd of the arsenic used time of sb oxide, and throughput improves about 10%.
(3) a kind of arsenic-free glass bottle component selection of the present invention is reasonable, proportioning is accurate, do not use the arsenic sb oxide, make the same quality standard of glass of finings but can reach with using the arsenic sb oxide, in the wavelength of 500-650nm, the transmittance of glass of the present invention is greater than 97%.
(4) the present invention does not increase with the production cost that has the glass unit product that uses the arsenic sb oxide to make finings now, has very big market potential.
