Embodiment 1
[0027] (1) Preparation of immersion plating solution:
[0028] Weigh sodium oleate and ethanol at a weight ratio of 5%, stir evenly, and prepare an immersion plating solution.
[0029] (2) Immersion plating:
[0030] The special device used for immersion plating of the present invention is as image 3 As shown, it includes winding barrels 1 arranged in sequence, the braided core wire 10 is wound on the winding barrel 1, the dipping tank 3 is arranged behind the winding barrel 1, and the dipping tank 3 is filled with an immersion plating solution 6, The pressure wheel 4 is installed in the dipping tank 3 through the bracket 5, and a gear wheel (gear wheel 2 and gear wheel 8) is installed on both sides of the pressure wheel 4, and the braided core wire 10 discharged from the winding barrel 1 is sequentially passed through The gear wheel 2 and the pressure wheel 4 enter the dipping tank 3, so that the dipping solution 6 is uniformly dipped on the surface of the braided core wir...
Embodiment 2
[0041] The production process and production equipment are the same as in Example 1, the difference is that the ratio of sodium oleate and ethanol is changed, and the performance comparison of the coaxial cables produced by the immersion plating solution under different ratios is tested, as shown in Table 3.
[0042] Testing standard: adopt GB / T 2423.18-2000.
[0043] Table 3. Comparison of the effects of antiseptic compositions with different formulations and the prior art (200610108985.5).
[0044]
[0045] In Table 3: the ratio of sodium oleate to ethanol is a weight ratio.
[0046] analyze:
[0047]It can be seen from Table 1 that when the weight ratio of sodium oleate and ethanol is 5%, the best anti-corrosion performance and electrical performance can be obtained. As the content of sodium oleate increases, the thickness of the coating will increase, and the drying and film-forming time will be prolonged, but its anti-corrosion and electrical properties have not been...
Embodiment 3
[0048] Example 3: Performance comparison of coaxial cables under different preparation processes
[0049] The production process and production equipment are the same as in Example 1, the difference is that the immersion plating time and drying temperature in the immersion plating process are changed, and the performance comparison of the coaxial cables produced under different process conditions is tested respectively, as shown in Table 4.
[0050] Table 4. Performance comparison of coaxial cables with different process parameters under 5% immersion plating solution.
[0051]
[0052] In Table 4: dipping time and drying time are calculated per meter of coaxial cable (braided core wire).
[0053] analyze:
[0054] It can be seen from Table 4 that with the increase of immersion plating time and drying temperature, the coating thickness will increase appropriately, the anti-corrosion performance will be improved, and the drying time will be reduced.
[0055] In summary, the...
