Embodiment Construction

[0006] According to SiO 2 69-70%, AL 2 o 3 Accounting for 1~2%, B 2 o 3 Accounting for 1 to 1.5%, B 2 O accounts for 8-9%, K 2 O accounts for 2 to 3%, Na 2 O accounts for 9-10%, CaO accounts for 1-1.5%, MgO accounts for 0-1%, S 2 O accounts for 1.5-3%, Li 2 O accounts for 1.5-2% of the component ingredients, weighing of raw materials→stirring→feeding→melting, clarification, homogenization in electric furnace→drawing tube forming→fine cutting round mouth→inspection and packaging→storage. Thereby obtaining lead-free special glass for energy-saving lamps with a linear expansion coefficient of 92±2% and a softening point of 640±10°C.

Abstract

The invention relates to a chemical ingredient component of lead-free special glass for an energy-saving lamp, in particular to a chemical ingredient component of lead-free special glass for manufacturing the energy-saving lamp and belongs to the technical field of energy-saving lamp manufacturing. The chemical ingredient component contains SiO2, AL2O3, B2O3, B2O, K2O, Na2O, CaO, MgO, S2O and Li2O and is characterized in that the SiO2 accounts for 69-70%, the AL2O3 accounts for 1-2%, the B2O3 accounts for 1-1.5%, the B2O accounts for 8-9%, the K2O accounts for 2-3%, the Na2O accounts for 9-10%, the CaO accounts for 1-1.5%, the MgO accounts for 0-1%, the S2O accounts for 1.5-3%, and the Li2O accounts for 1.5-2%. The chemical ingredient component has the advantages that the chemical ingredient component saves energy, is environmentally friendly and can adapt to high-speed lamp-manufacturing production lines, a manufacturing softening point is low, linear expansion coefficients are small, and the properties of the materials are long.

Description

technical field [0001] The invention relates to a chemical batching composition of lead-free special glass, which is especially suitable for making the chemical batching composition of lead-free special glass for energy-saving lamps, and belongs to the technical field of energy-saving lamp manufacturing. Background technique [0002] The glass used for energy-saving lamps currently on the market has a relatively high lead content in its chemical ingredients. As we all know, lead will produce lead evaporation when it encounters a certain temperature. And determined by the processing technology of glass products, all kinds of glass products are obtained under high temperature conditions. Therefore, the environmental pollution of the glassware production workshop is relatively serious, and the phenomenon of lead poisoning of the operating workers occurs from time to time. Furthermore, even if we have obtained the desired glass tube, when this high-lead or medium-lead glass tu...
