Abstract
The invention discloses an arsenic-free glass bottle, which solves the problems that the conventional food packing glass is not favorable for human health and environmental protection and cannot reach state specified standards due to higher arsenic and antimony dissolution amount. The arsenic-free glass bottle is prepared from raw materials comprising the following components in part by weight: 51 to 63 parts of quartz sand, 3 to 9 parts of lithium (or sodium or potassium) feldspar, 12 to 19 parts of calcite, 0 to 20 parts of dolomite, 1 to 3 parts of calcium sulfate, 0 to 2.2 parts of fluorite, 0 to 3 parts of sodium fluosilicate, 15 to 21 parts of soda ash, 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. The components are mixed uniformly, melted, molded and annealed to form the arsenic-free glass bottle according to the conventional glass bottle manufacturing method. The arsenic of the arsenic-free glass bottle is far below the state specified dissolution permissible amount, so the arsenic-free glass bottle has no toxic or side effect on the human body and does not produce environmental pollution; and at the same melting temperature, the clarifying time is shortened to half time of using arsenic and antimony oxides, and the production capacity is improved by 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...
