High-quality white bottle production

The high-quality glass bottle is a colorless glass bottle, with high transparency, good visibility, and great customer satisfaction.It is the most ideal packaging material for high-quality white wine and Japanese chemical products, and is also a high-quality product in the glass bottle industry.

No matter how many types of glass its ingredients are used, it can be used in combination with manufacturing technology requirements, high whitening ingredients, color brightness removal requirements, and other performance requirements. Lord, I have made some adjustments to this foundation. The key point is that the required high whiteness is required, and the content of glass and iron is required. A form of glass-based iron (Fe2 03) that is similar to that of glass (Fe2 03). The content and proportion of these different types of glass are not the same, and the composition of the glass is yellow-yellow-green-blue, which is the main factor in the effect of the colorless glass. That is, the coloring ability of the iron is 10 times higher than that of the iron. Because of this, it is necessary to provide high glass whiteness, which is required in the production process, to reduce the amount of iron content in the glass, and to reduce the effect of reducing the glass whiteness. In addition, it is necessary to refrain from adding colors such as irons, bolts, etc., and the general specification of the quasi-high-white table 2-43 rows of domestic high-whitening ingredients in bottles and casings.

The content of SiO2 and Al203 in the high white powder bottle is 73%~75%, and the content of Al203 is generally 1%~2%, the content is low and the glass is brittle. Mg0 glass melt has a certain effect on molding, but the quality of raw materials is not good, and the ingredients are not designed at the time of introduction, and other ingredients are generally available. High-quality glass bottles, in addition to the requirement for good optical transparency, also require a constant refractive index, where there is a basic component, but it is necessary to add a small amount of high-refractive components such as BaO, etc. Introducing a small amount of Ba0 enhances the refractive index of the glass, density, light flux chemical properties, and accelerates the ability of the glass to melt.

  Raw material selection  

The raw material type is the selection of technical requirements, the performance of Japanese glass is certain, and the required amount of materials is required. High production white material raw material for glass, maximum ground fall at the top of the neck, medium content of glass raw material. Excluding SiO2 and CaO raw materials, we use persimmon raw materials, and other chemical raw materials of choice. The content of SiO{2 in the glass component of the high whitening material is generally 72%.The content of Fe and O3 in the silica sand is limited to 0.02% or less. Fe2 O3 content in limestone is high, calcite (Fe2 O3<0.015%) is used as a general whitening material, or silicate CaO, calcite water content is less than 1%, Ca0 content is more than 55.5%. The general quality of chemical raw materials is low, and the quality indicators are determined. Al2O3 in the high whitening agent component. Due to the high temperature and high melting temperature of the industry, Al2O3 is generally available at 1.0%~1.0%. Medium purity NaCI content is less than 0.5%. Moisture content is less than 0.5%, purity is less than 98.5%.
The key is to remove the combined base glass component, clear and clear, and remove the color. The use of production-enhancing whitening agents has the effect of clarifying and decolorizing at the same time. Among them, white arsenal is the chemical raw material with the best performance, but white arsenal has more toxic properties, and in recent years, it has been replaced by a cleaner cleaner with a slightly lower toxicity. At present, there are many companies using combination additives, such as S-type combination additives, oxidation, oxidation, clearing, decolorization, auxiliary melting effect, dosage 0.35% left and right, equivalent to 0.4% dosage of As2 O3. Clear and clear dosage, kiln type, melting temperature, compounding material ratio, and chemical conversion index (REDOX) have been determined.
The purpose of glass bleaching is to provide high product clarity and "whiteness", which includes chemical bleaching and physical bleaching. Chemical decolorization is generally included in the formulation. Use strong coloring Fe2+ to give weak coloring Fe3+, chemical compound to form zero color (FeF6)3-also chemical bleaching, chemical bleaching only weak coloring, but impossible to completely eliminate. Useful chemical decolorizing agents include silicic acid, nitric acid, and clear clearing agents. Physical decolorization is the process of color reciprocity to remove the glass's natural yellow and yellow-green colors. Normally used for physical bleaching, for making glass to give light blue color and neutralizing pale green color, for making glass to give blue color and neutralizing light yellow color, to fix the coloring for white coloring, and to make the coloring effect more difficult. restraint.
Bottle glass production is commonly used for physical bleaching. The dosage of decolorization is determined by the Fe2 03 content in the main base glass. Yuyu quartz sand has the highest dosage, Fe2 O3 in quartz sand has basically determined the content of iron in glass, and the usual amount of Fe2 O3 in quartz sand has determined the amount of decolorization. There are many factors that influence decolorization, the main content of iron, the amount of As203, Sb2 O3 or CeO2, the melting temperature, the moisture content of the ingredients, the amount of glass, the thickness of the furnace structure, etc.
At the time of production whitening, the most important dosage is for bleaching.

Glass production usually uses a certain amount of glass production materials. The iron content of high-quality white material production is limited to a limited amount of glass, and the amount of glass is not used. Glass must be selected, washed, and removed before purchase. After joining the glass, the dosage of the powder is insufficient, and the proportion of the available glass is proportionally increased.
