Abstract
The invention relates to a manufacturing method of a water blocking powder half-dry type optical cable. Water blocking powder is adopted to replace cable paste in production of layer-stranding central beam tube type optical cables, the water blocking powder is high water-absorbing acrylic resin powder, the water blocking powder is enabled to be distributed between a cable core (between a sleeve and a reinforcing piece and between sleeves) and an armor layer or an inner/outer sheath, and between the inner sheath and the armor layer, wherein the armor layer refers to materials such as a steel strip/ an aluminum strip/a steel wire/ a nonmetal reinforcing material-aramid fibers or glass fibers, thereby achieving a purpose of longitudinal water blocking of optical cable products. The manufacturing method of the water blocking powder half-dry type optical cable comprises the steps of (1) using water blocking powder to act as a water blocking layer in the procedures of manufacturing a cable core of the optical cable; (2) directly using the water blocking powder to act as a water blocking layer in the procedures of the sheath; and (3) using the water blocking powder to act as a water blocking layer in subsequent manufacturing besides the procedures of manufacturing the cable core and the sheath of the optical cable.
Description
Technical field
The invention belongs to fiber optic communications field, more particularly, to a kind of manufacture method of the water blocking layer of optical cable.
Background technology：
Existing field optical cable (layer twists or central beam tube type) cable core (includes between sleeve pipe and reinforcement and sleeve pipe and sleeve pipe
Between), (armor refers to armor：Steel band/aluminium strip/steel wire/the material such as nonmetallic reinforcement material-aramid fiber or glass fibre) it
Between or interior (outward) sheath between；Between inner sheath and armor；The technology that blocks water mainly adopts cable cream (oil product of synthesis) to hinder
Water, less use waterstop or water blocking yarn block water.
Problem of the prior art and shortcoming：Cable cream is a kind of material being very difficult to and decomposing, if optical cable uses cable cream to hinder
Water, it is very difficult to cleaning is it is necessary to dip in upper other solvent using solid matter (as paper or cloth etc.) during stripping of constructing in the wild
Ointment on optical cable core could be cleaned out by (as ethanol or acetone soln etc.), and such as scene can not be handled well and clean out
The pollutant that scene is left just are very easy to cause the pollution to surrounding (including water or soil)；Production in the factory
In journey, cable cream equally also can be to the environment of factory, and the pollutant after cleaning cable cream are also to be difficult to reclaim and process simultaneously
.
Substitute cable cream using water-proofing powder in optical cable, reduce the pollution to environment.
Content of the invention
The present invention is directed to the deficiencies in the prior art, is replaced using water-proofing powder in layer strand, the production of central-beam tube type fiber optic cable
Cable cream, water-proofing powder, is high water absorption acrylic resin powder, and (high water absorption acrylic resin powder, english abbreviation is-water to water-proofing powder
Blocking powder or super absorbent powder), make water-proofing powder be distributed in cable core and (include sleeve pipe and reinforcement
Between and sleeve pipe and sleeve pipe between), (armor refers to armor：Steel band/aluminium strip/steel wire/nonmetallic reinforcement material-aramid fiber or
The materials such as glass fibre) between or interior (outward) sheath between；Between inner sheath and armor；Thus reaching the longitudinal direction of cable manufactures
Block water.

Specific embodiment
The manufacture method of water-proofing powder half dry type optical cable of the present invention, comprises the steps：
(1) water-proofing powder is used as the manufacture method of water blocking layer in optical cable core manufacture：
In the production of optical cable core, water-proofing powder is used as water blocking layer, as shown in Figure 1, Figure 2, Fig. 3
(2) water-proofing powder is directly used as the manufacture method of water blocking layer in sheath operation.
In the production of sheath operation, water-proofing powder is used as water blocking layer, such as Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, figure
