Abstract
The invention discloses an arsenic-free glass bottle, which aims to solve the problem that the existing glass bottle (for food packaging) with high arsenic and antimony releases is bad for human health and environmental protection and can not meet the state-specified standards. The arsenic-free glass bottle is prepared from the following compositions in part by weight: 100 parts of quartz sands, 6 to 18 parts of lithium (or sodium, potassium) feldspars, 24 to 38 parts of calcites, 0 to 40 parts of dolomites, 2 to 6 parts of sodium nitrates, 0 to 4.4 parts of fluorites, 0 to 6 parts of sodium fluosilicates, 30 to 40 parts of calcined sodas, 0.7 to 0.9 parts of sodium sulfates, 1.5 to 1.9 parts of calcium sulfates, and 0.7 to 0.9 parts of cerium oxides through the steps of evenly mixing the compositions, and then carrying out even blending, founding, forming and annealing on the obtained mixture according to the existing glass manufacturing method so as to obtain the arsenic-free glass bottle. In the arsenic-free glass bottle of the invention, the arsenic content is far below the state-specified allowable release, therefore, the arsenic-free glass bottle has non-toxic side effects on the human body and does not lead to environmental pollution; and at a same melting temperature, the clarification time is reduced to half of that by using arsenic and antimony oxides, therefore, the production capacity is about 10 percent.
Description
technical field [0001] The invention relates to an arsenic-free glass vessel, 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 in almost every aspect of people's production and life. However, in the process of glass production, processing and use, it will also cause some negative effects. For example, in the production of existing glass, due to the use of harmful arsenic and antimony substances, it is easy to cause harm to the human body. [0003] Arsenic and antimony are represented by As 2 o 3 , Sb 2 o 3 It is widely present in various glasses and acts as a clarifier to eliminate air bubbles. When using arsenic oxide as a fining agent, low temperature As 2 o 3 absorb NaNO 3 The oxygen released from the decomposition becomes As 2 o 5 , As 2 o 5 At high temperature, it decomposes to release oxygen, and the oxygen ente...
