Method for cleaning inner wall of outer sleeve of plastic blending flame-retardant optical cable

Abstract

The invention relates to a method for cleaning the inner wall of an outer sleeve of a plastic blending flame-retardant optical cable. The plastic blending flame-retardant optical cable comprises a metal tube, wherein one end of the metal tube is sealed, a sponge sleeves the sealing end, a joint is arranged at the other end of the metal tube, a water pump is connected through a water tube, a waterspraying opening is formed in the middle section of the metal tube, the middle section is sleeved with a sponge sleeve, a plastic sleeve is arranged on the inner wall of the sponge sleeve, a convex edge with a triangular section is arranged on the inner wall of the plastic sleeve, annular convex edges are arranged at the left end and the right end of the inner wall of the plastic sleeve, sphericalgrooves are formed in the side walls of the annular convex edges, balls are arranged in the spherical grooves, deep grooves are formed in the bottom of the spherical grooves, springs are arranged inthe deep grooves and abuts against the balls, annular grooves are formed in the two sides of the water spraying opening of the metal tube, and the balls roll in the annular grooves, and when the metaltube is inserted into the outer sleeve, the sponge makes contact with the inner wall of the outer sleeve. The sponge at the front end of the metal tube is subjected to primary dust removal, secondarycleaning is carried out through the sponge, and paraffin dilution is finished, the toughening agent is spread out and is coated on the inner wall of the outer sleeve through the sponge, so that the toughening effect is achieved.

Description

Technical field: [0001] The invention relates to the technical field of optical cables, in particular to a method for cleaning the inner wall of an outer casing of a plastic blended flame-retardant optical cable. Background technique: [0002] In recent years, nanotechnology has attracted widespread attention in the field of flame retardancy. Studies have shown that nanomaterials only need a small amount of addition (generally less than 5%) to achieve a more obvious flame retardancy effect. Therefore, the preparation of flame-retardant nanocomposites is an important component in the field of flame-retardant technology, and is highly regarded by researchers. Layered inorganic nanomaterials are one of the most effective filler materials in flame-retardant nanocomposites. When layered inorganic nanomaterials are dispersed in the polymer matrix at the nanoscale, they can significantly improve the mechanical properties of nanocomposites. , thermal stability and flame retardant p...

Problems solved by technology

[0007] After the jacket is prepared and stored, it is easy to get dust for a long time. The cleaning method is mostly to rinse with water, but it is easy to leave water stains and it is difficult to dry. After the optical cable is inserted, the water stains will penetrate into the plastic blended optical cable and affect the optical cable.
