Abstract
The invention discloses an arsenic-free glass bottle. The objective of the invention is to overcome the problem that the dissolving-out amounts of arsenic and antimony in conventional glass for food package are high and cannot reach state-specified standard, which is unfavorable for human health and environmental protection. The arsenic-free glass bottle is prepared from the following raw materials by weight: 51 to 63 parts of quartz sand, 3 to 9 parts of lithium (or sodium and potassium) feldspar, 12 to 19 parts of calcite, 0 to 20 parts of dolomite, 1 to 3 parts of sodium nitrate, 0 to 2.2 parts of fluorite, 0 to 3 parts of sodium fluosilicate, 15 to 21 parts of sodium carbonate, 0.1 to 0.5 part of sodium sulfate, 0.3 to 1 part of calcium sulfate and 0.1 to 0.5 part of cerium oxide. Theabove raw materials are uniformly mixed; and then uniform mixing, melting, shaping and annealing are successively carried out according to conventional manufacturing methods for glass bottles so as toprepare the arsenic-free glass bottle. The arsenic content of the arsenic-free glass bottle is far lower than an allowable dissolving-out amount prescribed in national standard, so the arsenic-free glass bottle is free of toxic and side effect to human beings and does not produce environmental pollution. Under same melting temperature, the clarification time of the arsenic-free glass bottle is 1/2 the clarification time of glass using arsenic antimony oxide, and production capability is improved by 10% or so.
Description
technical field [0001] The invention relates to an arsenic-free glassware, in particular to an arsenic-free glass bottle. Background technique [0002] Glass technology is a traditional industry. Due to a series of excellent properties of glass itself, it is widely used, covering almost all aspects of people's production and life. However, in the production, processing and use of glass, some negative effects will also be caused. For example, in the production of existing glass, arsenic and antimony substances that are harmful to the human body are used, which are easy to cause harm to the human body. [0003] Arsenic and antimony are widely present in various glasses in the form of As2O3 and Sb2O3, respectively. As fining agents, they play the role of eliminating bubbles. When arsenic oxide is used as a clarifying agent, the low temperature As2O3 absorbs the oxygen released by NaNO3 to become As2O5, and when As2O5 is high temperature, it decomposes to release oxygen, and t...
