Embodiment Construction

[0012] Take the oxide composition of an energy-saving lamp glass as an example:

[0013] Unit (gram)

[0014] Oxide SiO 2 al 2 o 3 CaO MgO Na 2 o K 2 o B 2 o 3 BaO total Wt% 65.00 1.50 8.00 2.50 14.5 2.50 1.50 4.50 100

[0015] First, prepare CeO with a total mass of 0.5 grams 2 , Fe 2 o 3 、TiO 2 , La 2 o 3 、 Bi 2 o 3 Five kinds of oxides, among which CeO 2 The content is 0.25 g, Fe 2 o 3 The content is 0.15 g, TiO 2 The content is 0.07 g, La 2 o 3 The content is 0.015 grams, Bi 2 o 3 The content is 0.015 grams.

[0016] Then, the ingredients in the table and the content of the above-mentioned ingredients are calculated to obtain the ingredient list, and various oxides are introduced with mineral raw materials and chemical raw materials, and weighed and mixed.

[0017] Next, the above-mentioned ingredients are placed in a glass tank kiln for melting. The glass melting process includes a series of physical,...

Abstract

The invention relates to a piece of ultraviolet ray absorbing glass which is particularly applicable to making glass of an energy-saving lamp tube. According to the glass, an additive is formed by five oxides, including CeO2, Fe2O3, TiO2, La2O3 and Bi2O3, and ultraviolet rays can be absorbed by the five oxides to the maximum limit. If the total mass of the oxides in the energy-saving lamp tube is 100g, the total mass sum of the five oxides of CeO2, Fe2O3, TiO2, La2O3 and Bi2O3 ranges from 0.5g to 5g, and the ultraviolet rays can be effectively absorbed. The five oxides of CeO2, Fe2O3, TiO2, La2O3 and Bi2O3 are of certain mass ratios. By using the method, the glass self has the capability of absorbing the ultraviolet rays, and the radiation ultraviolet rays of an energy-saving lamp can be directly and simply reduced with high efficiency. The glass can remarkably improve the effect in absorbing the ultraviolet rays emitted from the lamp tube, and has a certain environment-friendly function.

Description

technical field [0001] The invention relates to an ultraviolet-absorbing glass, which is especially suitable for making energy-saving lamp lamp tube glass. The glass can absorb ultraviolet rays emitted by plasma in the lamp tube, and belongs to the inorganic chemical technology. Background technique [0002] Ultraviolet rays can cause fading and aging of paper, plastic products, textiles, furniture, etc., affecting the beauty and durability of these substances. In addition, it can age the skin and induce diseases such as skin cancer and cataracts. Therefore, in the fields of construction, automobiles, electronic appliances, etc., it is necessary to cut off ultraviolet rays through glass, so glass with ultraviolet absorption function has attracted widespread attention. With the improvement of building decoration and decoration level, energy-saving lamps and other electric light sources are widely used, and the ultraviolet rays in the lamp tubes can be radiated through the gl...
