Description
Technical Field
The invention belongs to the technical field of cable production, and particularly relates to a special lead-antimony alloy for a large-span tensile butterfly-shaped optical cable.
Background
The butterfly-shaped optical cable, also called as a rubber-insulated fiber cable, is an optical cable applied to a subscriber drop section in a Fiber To The Home (FTTH) network in a large scale, is also applicable to optical cables of subscriber drop sections of networks such as FTTO, FTTB and the like accessed by other optical fibers, and is called as a butterfly-shaped optical cable because the cross section of the optical cable is like a butterfly. As an indoor optical cable, the butterfly-shaped optical cable has good bending performance, and the flexible characteristic of the lead-antimony alloy can meet the preparation requirement of the butterfly-shaped optical cable.
The traditional direct smelting method of the lead-antimony alloy is characterized in that firstly, lead is melted and then antimony is added, and secondly, antimony is melted and then lead is added. Because the melting point of the lead is low and the melting point of the antimony is high, in the process of melting the lead and adding the antimony, the melting temperature of the lead is greatly increased to the melting point of the antimony to be beneficial to melting the antimony, so that the melting can be carried out in a dissolving mode when the antimony is added, and the melting speed is high; however, lead vapor is easily generated due to the overhigh temperature, and the lead vapor is harmful to human bodies and the environment. When the temperature is not high enough and is lower than the melting point of antimony, the specific gravity of antimony is smaller than that of lead and the antimony floats on the liquid surface of lead, so that the antimony is dissolved in a diffusion mode and is slow, actually, the antimony is added at the moment, the antimony absorbs heat to cause lead liquid on the surface to solidify and wrap the lead liquid on the surface of the antimony, the diffusion is more difficult or even impossible, the antimony can be diffused and dissolved only if the temperature is continuously raised and the lead solidified on the surface is melted again, and therefore the smelting temperature is raised again, the smelting time is longer, the absorption rate of the antimony is low, and the loss is large. If the antimony is melted first and then the lead is added, because the content of the lead-antimony alloy antimony is low, the adding amount is too small when the antimony is melted first, the melting is difficult, a crucible is heated for a long time, the damage is serious, the service life is short, when the lead is added at high temperature, the antimony solution is rapidly solidified due to the large lead amount added at one time, the temperature needs to be continuously increased, the melting time is prolonged, and the rapid melting is not facilitated; if the lead is added too little, a large amount of lead steam is generated, the lead steam is added while melting, the melting time is prolonged, and the lead steam is harmful to the environment and human bodies.
Therefore, it is necessary to provide a new preparation process for producing the special lead-antimony alloy for the large-span tensile butterfly-shaped optical cable.
