Novel lead-free energy-saving lamp glass tube

Abstract

The invention discloses a novel lead-free energy-saving lamp glass tube which comprises, by mass, 46-52% of quartz sand, 18-24% of soda ash, 5-8% of potassium feldspar, 1-3.5% of clarifying agents and 16-22% of small materials, wherein the clarifying agents are mixture of cerium oxide, sodium fluorosilicate and sodium chloride in the mass ratio of 1:1.5:1, and the small materials are mixture of dolomite, sodium nitrate and borax decahydrate in the mass ratio of 5.5:1:1. The potassium feldspar and the soda ash substitute for potassium carbonate in the prior art with raw material not changed greatly, and raw material cost of the novel lead-free energy-saving lamp glass tube is reduced by 50 RMB to 400RMB per ton as compared with that of the prior art under the circumstances that the production environment and conditions are unchanged, and the production quality is not reduced or improved.

Description

technical field [0001] The invention relates to a novel lead-free energy-saving lamp glass tube. Background technique [0002] The energy-saving lamp industry has a good development prospect. Internationally, countries all over the world are promoting the use of energy-saving lamp products. Domestically, with the deepening of national promotion of energy-saving products, China is undoubtedly a huge potential market. At present, there are nearly 30 domestic manufacturers of energy-saving lamps with a certain production scale, and the total annual output exceeds 4 billion. [0003] In the domestic and foreign markets, the original glass tubes of energy-saving lamps containing lead materials have been eliminated, and the transition to new lead-free materials is gradually carried out. Therefore, the new glass tubes of energy-saving lamps made of lead-free materials will become the leading products in the market. [0004] Production statistics of major domestic energy-saving lam...
