Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides novel environment-friendly glass suitable for glass bottle and can production, which comprises raw materials and a composite physical decolorant, wherein the raw materials comprise the following components in percentage by weight: SiO 2268-75% of B2O31 to 5% of Al2O31.5 to 2.5% of CaO, 8 to 12% of CaO, 1 to 5% of MgO, and Na2O+K212-16% of O, 0-1.0% of BaO, and La2O30.1 to 2.0% of CeO20.2 to 1.0% of Nd2O30 to 0.05 percent; the composite physical decolorant accounts for 0.2-0.5% of the total weight of the raw materials. 0.01 to 0.1 percent.
The composite physical decolorant is one or a mixture of Nd2O3, Er2O3 and CoO. The Nd2O3, the Er2O3 and the CoO in the composite physical decoloring agent are mixed according to the weight ratio of 10:10: 1-100: 100: 1.
Removal from glass batchAfter the sodium fluosilicate is melted, fluoride gas is not released to pollute the environment; in order to promote melting of the glass, in addition to B, the glass composition2O3Externally reintroducing La2O3To promote melting of the glass: b is2O3The fluxing agent is a strong fluxing agent, and can obviously reduce the high-temperature viscosity of the glass; newly introduced La2O3The viscosity of the glass at the melting temperature can be reduced at high temperature, and the melting and the clarification of the glass are promoted; further La2O3The introduction of (2) also plays a role in improving the chemical stability of the glass.
The following table, table 1, shows the parameter comparisons for each example: table 1 has Er2O3 written
TABLE 1
As shown in the table 1, the raw materials and the decolorizing agent provided by the invention do not contain polluting components such as fluoride, arsenic trioxide, antimony trioxide and the like, and also do not contain nitrate and sulfate, and after the raw materials are removed, the glass batch does not release NO in the melting process2、SO2And the toxic gas pollutes the environment; to facilitate the fining of the glass, pure CeO is introduced2As a fining agent for glass, furthermore CeO2Can also play a role in chemical decoloration.
According to the raw material proportion, the preparation method of the novel environment-friendly glass suitable for producing the glass bottles and cans comprises the following steps:
s1, mixing the glass raw materials according to the weight percentage, heating the mixture in a high-temperature furnace at 1520 ℃ and 1550 ℃, and controlling the heating time to be 24-72h to obtain glass liquid;
s2, processing by adopting a bottle forming process, and cooling the glass liquid to 1180-1210 ℃ for forming;
s3, annealing the molded glass bottle at the annealing temperature range of 460-610 ℃, and then cooling to room temperature environment to obtain the bottle product.
Generally, glass bottles and cans are yellow green when no physical decolorant is added, so selenium and cobalt are required to be added for physical decoloration, and the action principle is as follows: selenium shows red in the glass to make up for the green in the glass, and cobalt shows color in the glass to be blue to make up for the yellow in the glass; however, selenium is easy to volatilize, and the color development in the glass is not very stable, so that the decoloring stability of selenium and cobalt is poor.
The added erbium trioxide has sharp absorption peaks in green wave bands so that the added erbium trioxide develops red color, can well make up for green color and has stable development, the neodymium trioxide has sharp absorption peaks in green wave bands and yellow wave bands so that the erbium trioxide develops purple red color, can well make up for yellow green color, and the neodymium trioxide is used for physical decolorization so that the cobalt dosage can be reduced and the physical decolorization effect can be improved; therefore, (neodymium oxide + erbium oxide + cobalt oxide) is adopted as the composite physical decolorant to replace (selenium + cobalt) composite physical decolorant, so that the physical decolorant has more excellent physical decolorant effect, not only can the instability problem of selenium decoloration be solved, but also the physical decolorant effect on bottles and cans can be improved.
The production process of the bottle can reduces the release of toxic and harmful gases in the raw materials and reduces the pollution to the environment.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
