(1) first on strengthening core, directly apply ointment;
(2) strengthening core after above-mentioned coating ointment is controlled mould by ointment amount and is removed unnecessary ointment;
(3) strengthening core, sleeve pipe and gasket for packing are passed through to stranded passage twisted synthesizing cable;
(4) factice for filling on the cable core of above-mentioned twisted synthesizing cable again;
(5) and then on cable core overlap upper jacket, thereby make optical cable.
The shortcoming of above-mentioned this method in actual production process is effectively to fill strengthening core surface, make finished cable be prone to the underproof situation of cable core block-water performance, the reason of its generation is: 1, due to what strengthening core deadweight produced, saggingly make to apply strengthening core after ointment when controlling mould (scraping cream mould) and stranded the passage by before twisting point through ointment amount, the ointment on surface is scraped off (see figure 1); 2, the phosphorus powder on strengthening core surface or dust are piled up and are stopped up in ointment amount is controlled nib, make strengthening core surface ointment not enough.These reasons cause cable core ointment lack of fill after stranding, and optical cable permeability performance is defective.
Summary of the invention
Technical matters to be solved by this invention is the shortcoming for prior art cable core ointment lack of fill, a kind of ointment fill process is provided, and this ointment fill process can effectively overcome strengthening core ointment lack of fill and cause sheath to produce the rear underproof problem of optical cable permeability performance.The technical scheme adopting is as follows:
An ointment fill process, is characterized in that: comprise the following steps:
(1) grafting yarn on strengthening core;
(2) on the strengthening core of above-mentioned grafting yarn, apply ointment;
(3) strengthening core after above-mentioned coating ointment is controlled mould by ointment amount and is removed unnecessary ointment.
Described strengthening core and a plurality of sleeve pipe of removing unnecessary ointment carries out twisted synthesizing cable by stranded passage, then overlaps upper jacket, just makes optical cable.
Scheme preferably, in described step (1), in strengthening core grafting after yarn, yarn and strengthening core are screw shaped, and the screw thread that yarn is projection.
A scheme, the number of described yarn is one.
Another kind of scheme, the number of described yarn is at least two.
More excellent scheme, described any two one threads are grafting or oppositely grafting in the same way.
Scheme preferably, described yarn adopts polyester material to make.Yarn can be also that other materials are made.
The optical cable that this technique is applicable to be added with bed course produce and not the optical cable of the cushioned layer metal shielding structure that tangles that the optical cable of structure is produced and non-metal reinforced layer tangles produce.
The present invention's beneficial effect is against existing technologies, on strengthening core, after first grafting yarn, carry out again ointment filling, yarn and strengthening core form a screw rod shape, yarn is the screw thread of projection, after factice for filling, while controlling mould, stranded entrance and passageway through ointment amount, the yarn of projection can not wiped off ointment around completely, keep strengthening core surface to have enough ointment, the permeability performance of guaranteeing to produce rear optical cable is qualified; On strengthening core, first after wrapped bundle yarn, carry out again ointment filling, when strengthening core adopts phosphatization steel wire, the width of controlling mould more than ointment amount due to the grafting pitch of yarn is large, when in production, strengthening core is ceaselessly controlled mould by ointment amount, phosphorus powder or dust that the yarn of projection is controlled ointment amount on mould as brush are taken away, make phosphorus powder or dust can not control on mould and accumulate in ointment amount, guarantee that there are enough ointment on strengthening core surface; When adopting the not pre-filled ointment of stranding when sheath carries out Pressure filling technique, outstanding yarn is equivalent to increase strengthening core local diameter, do not affect the external diameter of optical cable, and increase the gap between stranded rear sleeve, during filling, ointment more easily sees through gap and arrives strengthening core surface, makes strengthening core surface have enough ointment; This process is implemented convenient, and only need before the gel filling device of former cabling device, increase yarn winding device can realize.
