Problems solved by technology

In view of the special manufacturing process and technical requirements of the fiber optic panel, after ordinary absorbing glass filaments are inserted into the fiber optic panel, the diameter of a single absorbing filament is on the order of microns, so it cannot effectively absorb stray light at all.
[0003] In addition, glass produced in the prior art to absorb stray light in fiber optic panels generally has poor devitrification resistance

Abstract

The invention discloses glass used for absorbing an optical spectrum with the wavelength being 430-900nm for an optical fiber panel. The glass is prepared by the following raw materials in parts by weight: 200-300 parts of boric acid, 590-700 parts of quartz sand, 50-150 parts of aluminum oxide, 20-100 parts of sodium carbonate, 80-180 parts of potassium carbonate, 140-210 parts of calcium carbonate, 30-40 parts of zinc oxide, 10-30 parts of titanium dioxide, 50-100 parts of iron trioxide, 10-20 parts of cobalt sesquioxide, 5-10 parts of nickel peroxide, 10-15 parts of manganese dioxide and 5-10 parts of cerium dioxide. The glass used for absorbing the optical spectrum with the wavelength being 430-900nm for the optical fiber panel is obtained. At the thickness being 0.40 plus or minus 0.01mm, the optical spectrum penetration ratio of the glass is smaller than or equal to 5%. The melting glass does not contain stones, and the glossiness of the glass is high. The softening temperature is controlled to be 600 DEG C-700 DEG C, the temperature of 820 DEG C is kept for 2h, the devitrification cannot be generated, the devitrification resistance is good, and the chemical stability is good.

Description

technical field [0001] The invention relates to a glass for absorbing 430-900nm wavelength spectrum used in an optical fiber panel and a preparation process thereof. Background technique [0002] Ordinary absorbing glass has a high transmittance (≥10%) in the visible light range under the control of 1mm thickness, and the control thickness is less than 1mm, and the visible light transmittance will be further improved. Such as James Victor Jones; Edward Naishd Pauls patent 94194503.0 announced a "neutral gray absorbing glass containing manganese oxide that can maintain selenium during processing", visible light under the thickness control of 4mm The transmittance is 16-20%. In view of the special manufacturing process and technical requirements of the fiber optic panel, after ordinary absorbing glass filaments are inserted into the fiber optic panel, the diameter of a single absorbing filament is on the order of microns, so it cannot effectively absorb stray light at all. ...
