Embodiment 1

[0019] Use commercially available analytical pure chemical reagents, according to the composition and ingredients in Table 1:

[0020] Make up

[0021] Precisely calculate and weigh the raw materials, mix them evenly, and prepare batches for later use. The electric furnace is heated to 1400°C, and the batch materials are added in several times. After the feeding is completed, the temperature of the electric furnace is increased to 1500℃, and then the stirrer is started. After the glass is clarified for about 8 hours, the temperature is slowly reduced to 1400℃, and the material is discharged and cast into a glass rod, which is used for the acid-soluble flexible optical fiber image transmission beam The manufacturing exhibits excellent performance.

Embodiment 2

[0023] Use commercially available analytical pure chemical reagents, according to the composition and ingredients in Table 2:

[0024] Make up

[0025] Precisely calculate and weigh the raw materials, mix them evenly, and prepare batches for later use. The electric furnace is heated to 1400°C, and the batch materials are added in several times. After completing the feeding, the temperature of the electric furnace is increased to 1500°C, and then the stirrer is started. After the glass is clarified for about 8 hours, the temperature is slowly lowered to 1400°C, and the material is discharged and cast into a glass rod. The rod is used for the manufacture of acid-soluble flexible optical fiber image transmission bundles and shows particularly excellent performance.

Abstract

The invention discloses the composition of a cladding glass for flexible optical fiber image-transmission bundle, which is characteristic in: (1) well numerical aperture; (2) well chemical reliability; (3) well resistance to separate crystal for good technical match, and without impregnation phenomenon with the material glass.

Description

Technical field [0001] The invention relates to a composition of leather glass used for acid-soluble flexible optical fiber image transmission bundles, and belongs to the field of manufacturing flexible optical fiber image transmission bundles. Background technique [0002] There are generally two production processes for flexible optical fiber imaging bundles. One is the wire arrangement method, which involves winding double layers of coaxial monofilaments in an orderly manner, then bonding them with an organic adhesive and then cutting them into bundles. The second is the acid-soluble method. This method first manufactures three layers of coaxial monofilaments, then arranges them into bundles, heat-melts and draws them into multifilaments, and finally immerses them in an acid solution to remove the acid-soluble glass to form a flexible optical fiber bundle. There are also two methods for manufacturing three-layer coaxial monofilaments in the acid-soluble method: one is th...
