Performance test

The glass bottles obtained in examples 1 to 11 and comparative examples 1 to 4 were subjected to the evaluation of appearance quality, the internal pressure resistance test and the impact resistance test in accordance with GB 4544-Buck 2020 beer bottle, the results of which are reported in Table 1.

TABLE 1

As can be seen by combining examples 1-11 with Table 1, the beer bottle prepared by the method has the advantages of uniform and smooth color of the bottle body, smooth surface without bubbles, good appearance quality, and excellent internal pressure resistance and impact resistance of the glass bottle. As can be seen from example 10 and FIG. 1, the glass bottles produced were authentic Mars green beer bottles.

As can be seen from the combination of example 10 and comparative example 1 and table 1, the effect of using a common commercial clarifying agent on the fact that the coloring agent copper oxide cannot be promoted is exerted, the dispersibility of particles in the system is poor, so that the color of the bottle body is deviated and uneven, the bottle body is not the authentic marsie green color, and meanwhile, some very small bubbles are generated, and the appearance quality is obviously poor; the internal stress resistance and impact resistance of the glass bottle obtained in comparative example 1 were also significantly reduced.

As can be seen by combining example 10 and comparative examples 2 to 3 with Table 1, the color of the resulting glass bottles, whether the coloring agent or the dispersant is absent from the composite modifier, appears to be biased and non-uniform and is not the authentic Marsdow color; meanwhile, the glass bottle is accompanied by some appearance defects, the appearance quality is poor, and the internal stress resistance and the impact resistance of the glass bottle are reduced to a certain degree. The reason is that under the promoting action of the composite regulator, the coloring effect of the copper oxide can be effectively promoted, the color uniformity of a system is improved, and the gas discharge in the glass forming process can be further accelerated, so that the surface of the bottle body is smooth and bubble-free, and the appearance quality of the glass bottle is good. Meanwhile, the crystallization tendency of the glass can be reduced, the devitrification tendency and the crystallization speed of the glass are reduced, the overall gloss of the glass is improved, and the impurity dissolved in the glass is reduced to reduce the quality of the product, so that the comprehensive performance of the product is improved, and the internal pressure resistance and the impact resistance of the glass bottle are obviously improved.

It can be seen from example 10 and comparative example 4 in combination with table 1 that the forming temperature and annealing temperature are changed during the preparation of the glass bottle, which results in the apparent quality of the product being significantly reduced, and thus it can be seen that the preparation process and the raw material components of the product are complementary, and the raw material and the specific process parameters of the present application can significantly improve the apparent quality of the glass bottle and enhance the market competitiveness of the product.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
