Abstract
The invention discloses a glass tube of a novel high-efficiency energy-saving lamp, comprising the following components in percentage by mass: 67.2-67.5 percent of SiO2, 10.3-10.9 percent of Na2O, 5.6-6 percent of PbO, 5.1-5.3 percent of K2O, 3.9-4.1 percent of BaO, 2-2.3 percent of B2O3, 2.1-2.3 percent of Al2O3, 3.1-3.4 percent of CaO and 0.2-0.5 percent of MgO. When used, the invention greatly reduces lead content in a lamp tube and dust precipitation quantity of red lead at the same time and lightens environmental pollution.
Description
Technical field
The present invention relates to a kind of electricity-saving lamp Glass tubing.
Background technology
As everyone knows, electric light source products generally is a glasswork, and normally used is lead glass, and lead glass is divided into light red lead (low plumbous) glass by PbO (red lead) content, and its content is 11%; Middle red lead (middle lead) glass, its content are 20% and weigh red lead (high plumbous) glass that its content is 28%.Because the needs of glass processing, various electricity-saving lamps all adopt low lead crystal glass, generally are lead tolerance at 11% lead glass.Lead in the lead glass is through adding plumbous oxide or lead silicate introducing when preparing burden, in the use of lead glass, the dust of red lead can slowly be separated out, serious environment pollution.
Summary of the invention
The object of the present invention is to provide the energy-efficient lamp Glass tubing, can effectively solve lead tolerance height in the existing lead glass, in use, the dust of red lead can slowly be separated out, the problem of serious environment pollution.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: the energy-efficient lamp Glass tubing is characterized in that being grouped into by following one-tenth:
(A) silicon-dioxide SiO
2, mass percent is 67.2%~67.5%;
(B) sodium oxide Na
2O, mass percent is 10.3%~10.9%;
(C) plumbous oxide PbO, mass percent is 5.6%~6%;
(D) potassium oxide K
2O, mass percent is 5.1%~5.3%;
(E) barium oxide BaO, mass percent is 3.9%~4.1%;
(F) boron trioxide B
2O
3, mass percent is 2%~2.3%;
(G) alchlor A1
2O
3, mass percent is 2.1%~2.3%;
(H) quicklime CaO, mass percent is 3.1%~3.4%;
(I) Natural manganese dioxide MgO, mass percent is 0.2%~0.5%.
The present invention is owing to adopted technique scheme; Greatly reduce content plumbous in the fluorescent tube; The glass that adopts useless middle plumbous (PbO) content 20% of fine during production is that raw material replaces lead silicate or plumbous oxide; On the basis that adds other composition, the mass ratio of PbO is reduced greatly, and do not influence the performance of Glass tubing under the situation of reduction PbO mass ratio; In use simultaneously, the dust amount of separating out of red lead significantly reduces, and alleviates the pollution to environment.The present invention has realized turning waste into wealth, economizing on resources, and has reduced the products production cost, for making electricity-saving lamp the ideal glass material is provided.
Embodiment
Energy-efficient lamp Glass tubing of the present invention is got silicon-dioxide (SiO
2) 67.5kg, sodium oxide (Na
2O) 10.5kg, plumbous oxide (PbO) 5.6kg, potassium oxide (K

2O
3) 2.2kg, alchlor (Al
2O
3) 2.1kg, quicklime (CaO) 3.3kg, Natural manganese dioxide (MgO) 0.3kg, the promptly useless medium lead crystal glass content of main raw material plumbous oxide is 20%, and the iron in the silicon-dioxide, cobalt, nickel content are less than 0.01%, can improve optical throughput.The industrial chemicals that weighs up is mixed, stir, render in the tank furnace fusion cast glass then.Adopt No. 250 low sulphur heavy oil burning fusions, make it molten, pull out the electricity-saving lamp Glass tubing by client's order specification for behind the liquid bath of glass entering blowpipe.Through naturally cooling, cutting, check, packing, promptly get electricity-saving lamp Glass tubing of the present invention.
Glass tubing performance of the present invention is as shown in the table:
