Embodiment 1

[0044]A carbon fiber tow electroplating device, which includes a transmission guide roller 2, an electroplating tank 3, an anode metal plate 4, a fixed guide roller 5, and a conductive guide roller 7. It is characterized in that there are 2-5 electroplating tanks 3, and the first Above the input end of each electroplating tank 3, there are three transmission guide rollers 2 distributed in a triangle, and an anode metal plate 4 is distributed at the bottom of each electroplating tank 3, and fixed guide rollers 5 are respectively arranged above the two ends of the anode metal plate 4. There is a non-circular guide roller above the middle of the metal plate 4, a conductive guide roller 7 is arranged above between the electroplating tanks 3, a conductive guide roller 7 is arranged above the output end of the last electroplating tank 3, and the last electroplating tank 3 There are three transmission guide rollers 2 that are triangularly distributed behind the upper conductive guide ...

Embodiment 2

[0049] Use non-circular guide rollers as elliptical transmission guide rollers 6-2, the ratio of its major axis to minor axis is 1.2; set 2 electroplating tanks, and set 2 identical elliptical guide rollers in each electroplating tank; the rest The structure of the device is the same as in Example 1. The conductive guide roller 7 is a stainless steel guide roller. The anode metal plate 5 is a Ni plate.

[0050] Polyacrylonitrile (PAN)-based high-strength 24K carbon fiber 1 with a diameter of 7 μm was heat-treated in a desizing furnace at 650 ° C for 5 minutes, and the atmosphere was argon; Sodium aqueous solution cleaning tank for cleaning, and then enter the water washing tank to wash off the residual sodium lauryl sulfate on the surface of the carbon fiber with flowing deionized water. The content of sodium lauryl sulfate in the running water is 0.29g / L; then enter 2 Continuous nickel plating in a plating tank. The formula of the electroplating solution is: NiSO 4 ·6H 2...

Embodiment 3

[0054] The non-circular guide roller is used as an elliptical transmission guide roller 6-1, and the ratio of its major axis to the minor axis is 3.0; 5 electroplating tanks are set, and an elliptical transmission guide roller 6-1 with the same structure is arranged in each electroplating tank 1; All the other device structures are the same as in Embodiment 1. The conductive guide roller 7 is a copper guide roller. The anode metal plate 5 is a Ni plate.

[0055] The polyacrylonitrile-based 24K carbon fiber 1 with a diameter of about 7 μm was heat-treated in a desizing furnace at 700 ° C for 3 minutes, and the atmosphere was argon; next, the carbon fiber tow 1 was washed in an aqueous solution containing 2.0 g / L sodium lauryl sulfate tank for cleaning, and then enter the washing tank to wash off the residual sodium lauryl sulfate on the surface of the carbon fiber with flowing deionized water. The content of sodium lauryl sulfate in the running water is detected to be 0.47g / L;...

Abstract

The invention relates to a carbon fiber wire beam continuous metal electroplating process, which comprises: removing a sizing agent, washing with a surfactant solution, adopting carbon fibers as a cathode, adopting a plated metal as an anode, arranging a non-circular mechanical guide roller in an electroplating bath, driving the non-circular mechanical guide roller to rotate through a motor so as to drive the carbon fiber wire beam to periodically vibrate in the electroplating solution, electroplating on the carbon fiber surface, washing, and collecting the wire. According to the present invention, advantages of simpleness, practicality and low cost are provided, and the black core problem in the e carbon fiber wire beam can be well solved.

Description

technical field [0001] The invention relates to a process and a device for continuous metal plating of carbon fiber tow. Background technique [0002] With the rapid development of the modern electronic industry and the popularization of electronic and electrical equipment, the problem of electromagnetic radiation is becoming more and more serious. Electromagnetic wave radiation can interfere with surrounding electronic equipment, causing accidents and information leakage, posing a serious threat to information security such as computers and communications. In addition, electromagnetic radiation also has a serious impact on human health. [0003] Surface metallized carbon fiber has gradually become an important material for modern electronic radiation protection products and equipment. Surface metallized carbon fiber also has a wide range of uses in military, small and large capacity capacitors, magnetic films, electromagnetic shielding films for electronic equipment, and ...
