Abstract

The formulation of conic glass for color picture tube glass shell includes: PbO 15.00-21.00 wt%, CaO 2.20-3.80 wt%, MgO 1.50-2.50 wt%, K2O 7.10-9.00 wt%, Na2O 5.30-6.70 wt%, Al2O3 3.10-5.10 wt%, Sb2O3 0.15-0.25 wt%, SrO+BaO 3.70-10.70 wt%, except SiO2. The present invention introduces SrO and BaO to regulate X-ray absorption coefficient and controls the content of PbO 15-21 wt% to make the conic glass meet relevant technological requirement.

Description

The color picture tube glass bulb prescription of cone glass
Technical field
The present invention relates to a kind of prescription of crt glass, particularly a kind of prescription of making color picture tube glass bulb with cone glass.
Background technology
At present, colour picture tube production cone glass prescription commonly used has two kinds both at home and abroad: promptly 0138 prescription and FT-22H fill a prescription; As shown in the table.
Commonly use Cai look Xian Xiang Guan Cone glass formula both at home and abroad
Oxide SiO 2 PbO CaO MgO K 2O Na 2O A1 2O 3 Sb 2O 3 Fe 2O 3

FT-22H Surplus 23.0 3.80 2.55 8.00 6.70 4.00 0.15 ＜0.07
At present, there is change in crt glass factory slightly with part component in above-mentioned prescription or the prescription.Along with the progress of scientific development and society, human strong day by day to requirement on environmental protection.And in above-mentioned glass formula the content of PbO all more than 22%; Not only seriously polluted environment, and the batching cost of above-mentioned cone glass prescription, its price is very high under the existing market condition, influences economic benefit, has restricted the development of producing.
Summary of the invention
The object of the present invention is to provide a kind of content that not only can reduce PbO, adapt to environmental requirement, the color picture tube glass bulb prescription of cone glass that also can significantly reduce the batching cost simultaneously.
For achieving the above object, the prescription that the present invention adopts is: containing mass percent is 15.00～21.00% PbO, 2.20～3.80% CaO, 1.50～2.50% MgO, 7.10～9.00% K 2O, 5.30～6.70% Na 2O, 3.10～5.10% Al 2O 3, 0.15～0.25% Sb 2O 3, 3.70～10.70% SrO+BaO surplus is SiO 2
The present invention adjusts X-ray absorption coefficient by introducing strontium oxide, barium oxide, the content of plumbous oxide is controlled between 15～21%, both meet the relevant safety standards that prevents the X-ray injury human body of International Power association, and can satisfy the glass use technology requirement of chromoscope awl again.
