Problems solved by technology

Although these glasses exhibit good acid-soluble properties, there are some disadvantages at the same time: (1) the chemical stability of acid-soluble glasses is poor, and they are susceptible to corrosion after long-term use in the air; (3) When the monofilament is manufactured in the three-crucible, it cannot form a good match with the core glass and skin glass in the process, and it is made into a three-layer coaxial fiber
CN1103325 Acid-dissolved optical fiber imaging bundle single fiber acid-soluble glass attachment method has proposed another problem, that is, the impregnation phenomenon between the three layers of glass that exists in the monofilament made by the three-crucible method, once this phenomenon occurs, the performance of the image-transmission bundle will be affected. will drop drastically, or even fail to work at all.

Embodiment 1

[0019] Adopt commercially available analytical pure chemical reagents, according to the composition batching in Table 1:

[0020] composition

[0021] Accurately calculate and weigh the raw materials, stir them evenly and make batches for later use. Heat the electric furnace to 1300°C, and add the batch in several times. After the feeding is completed, the temperature of the electric furnace rises to 1400°C, and then the stirrer is started. After the glass is clarified for about 8 hours, the temperature is slowly lowered to 1300°C, and the material is cast into a glass rod, which is used for acid-soluble flexible optical fiber image transmission bundles. The fabrication showed excellent performance.

Embodiment 2

[0023] Adopt commercially available analytical pure chemical reagent, press the composition batching in Table 2:

[0024] composition

[0025] Accurately calculate and weigh the raw materials, stir them evenly and make batches for later use. Heat the electric furnace to 1300°C, and add the batch in several times. After the feeding is completed, the temperature of the electric furnace rises to 1400°C, and then the stirrer is started. After the glass is clarified for about 8 hours, the temperature is slowly lowered to 1300°C, and the material is cast into a glass rod, which is used for acid-soluble flexible optical fiber image transmission bundles. exhibited particularly excellent performance.

Abstract

The invention discloses the composition of an acid-dissolved glass for flexible optical fiber image-transmission bundle, which is characteristic in: (1) well acid dissolved feature; (2) well chemical reliability in air; (3) well resistance to separate crystal for good technical match; (4) without impregnation phenomenon with the material glass.

Description

technical field [0001] The invention relates to an acid-soluble glass composition used for an acid-soluble flexible optical fiber image transmission bundle, and belongs to the field of flexible optical fiber image transmission bundle manufacturing. Background technique [0002] There are generally two production processes for flexible optical fiber image transmission bundles. One is the wire arrangement method, that is, the double-layer coaxial monofilaments are wound in an orderly manner, and then bonded with an organic adhesive and cut into bundles. The second is the acid-soluble method, which first produces three layers of coaxial monofilaments, then arranges them into bundles, heat-melts and draws them into multifilaments, and finally immerses them in acid to remove the acid-soluble glass to form a flexible optical fiber bundle. There are also two methods for the manufacture of three-layer coaxial monofilament in the acid-soluble method: one is the tube-and-rod method, ...
