Abstract
The invention provides a formula of a light lead glass tube. 100 Kg of glass liquid raw materials comprise 215 Kg of SiO2, 63.94 Kg of Na2CO3, 15.77 Kg of KNO3, 6.78 Kg of K2CO3, 13.56 Kg of Na2B4O7, 21.19 Kg of CaCO3, 14.4 Kg of BaCO3, 23.39 Kg of lithium mica, 5.8 Kg of clarifying agent and 675 Kg of regenerated raw material crushed glass with the concentration of 62.5%; and the regenerated raw material crushed glass with the concentration of 62.5% is waste glass of old televisions for old-for-new service. The formula disclosed by the invention does not adopt the raw material lead silicate and the content of a heavy pollutant PbO in each 100 kilograms of the glass liquid is reduced compared with the previous formula and reaches 58%; and the luminance efficacy and the stretching performance of a product are improved, the product quality is ensured and the cost of each ton of the glass liquid is saved by more than 10%.
Description
Technical field: the present invention relates to a kind of prescription of light lead glass pipe, it is applicable to fields such as vacuum electronic, energy-saving electric light source, automotive industry.
Background technology: the conventional glass pipe by 100Kg glass metal formula for raw stock is: SiO
2, 215Kg; N a
2CO
3, 63.94 Kg; KN O
3, 15.77 Kg; K
2CO
3, 6.78 Kg; Pb
2SiO
4, 24.41 Kg; N a

3, 21.19 Kg; Ba CO
3, 14.4 Kg; Lithionite 23.39 Kg; Finings 5.8 Kg; Glass cullet 675 Kg; By the resultant after the above proportioning fusing, content is by weight percentage: SiO
2, 67%; A l
2O
3, 1%; CaO, 3.5%; B
2O
3, 1%; Na
2O, 11%; K
2O, 5.5%; PbO, 11%.Wherein PbO is a heavy contaminant, and product cost is high, and physical strength toughness is low, light is well-illuminated low, can not satisfy the production development needs.
Summary of the invention: the object of the invention is exactly the prescription that a kind of light lead glass pipe will be provided, and it can overcome the existing existing above problem of Glass tubing.The objective of the invention is to realize like this, the prescription of light lead glass pipe is characterized in that: by 100Kg glass metal formula for raw stock be: SiO
2, 215Kg; N a
2CO
3, 63.94 Kg; KN O

2, 0.2%; BaO, 4.5%; PbO, 4.6%.The present invention does not adopt the raw material silicon lead plumbate, and per hundred kilograms of glass metals have reduced heavy contaminant PbO than original formulation, reach 58%, have increased B
2O
3, 0.3% is strong fusing assistant, makes in the molten glass process and has reduced fuel.Reduced expensive K
2O has increased the cheap strong physical strength flexible A l that has
2O
3, 1%; Improved the well-illuminated and extension property of light of product, guaranteed quality product, glass metal per ton is than practicing thrift cost originally more than 10%.
Embodiment;
The prescription of light lead glass pipe is characterized in that: by 100Kg glass metal formula for raw stock be: SiO
2, 215Kg; N a

3, 21.19 Kg; Ba CO
3, 14.4 Kg; Lithionite 23.39 Kg; Finings 5.8 Kg; 62.5% regenerative raw materials glass cullet, 675 Kg; Described 62.5% regenerative raw materials glass cullet are the old televisor discarded glass of old for new service; By the resultant after the above proportioning fusing, content is by weight percentage: SiO
2, 68%; A l
2O
3, 2%; CaO, 3.3%; B
2O
3, 1.3%; Na
2O, 11.8%; K
2O, 4%; Li
2O, 0.3%; CeO
2, 0.2%; BaO, 4.5%; PbO, 4.6%.During practical implementation; Described 62.5% regenerative raw materials glass cullet are old televisor discarded glass that nobody shows any interest in, that environmental pollution is very serious, old for new service; Because contain 2% lead and other valuable metals and potassium, sodium ion in this glass, thus utilize old televisor glass bulb and televisor flat glass to replace lead and potassium, the sodium material of needs interpolation in the former batching, and do not adopt the raw material silicon lead plumbate; Per hundred kilograms of glass metals have reduced heavy contaminant PbO; Reach 58%, the industrial chemicals after weighing is according to a certain ratio packed into stirred 6 minutes uniformly in the stirrer, add the regenerative raw materials glass cullet that clean up after the pulverization process again; In stirrer, stirred 1 minute, and carried out melting when furnace temperature rises to 1550 industrial chemicals after sending stirring to when spending.
