Embodiment 1

[0012] The cable is coated with cross-linked polyethylene material by the extruder and pulled out from the die of the extruder. At this time, the outlet temperature is 200 ° C, and when the cable is 5 meters from the head of the extruder, the surface of the cross-linked polyethylene cable core is measured. The temperature is 120°C. Install a code printer here, and just print the code.

Abstract

The invention relates to a surface code spraying method for a crosslinked polyethylene cable wire core. The surface code spraying method mainly comprises the following step that when the surface temperature of the crosslinked polyethylene cable wire core is 110 to 130 DEG C, ink is used for code spraying and character printing. When the method is adopted for spraying codes and printing characters on the surface of the crosslinked polyethylene cable wire core, the adhesive force of printed characters can be improved, and the wear resistance of the printed characters can be enhanced.

Description

technical field [0001] The invention relates to a method for spraying codes on the surface of cable cores, in particular to a method for spraying codes on the surface of cross-linked polyethylene cable cores. Background technique [0002] In the traditional wire and cable manufacturing, relevant standards stipulate that the surface of insulated cores with more than 5 cores needs to be printed or coded for sub-identification. In the GB / T9330.3 standard, it is stipulated that the marking of the cross-linked polyethylene core is now using the inkjet printer or the special ink printing process for cross-linked polyethylene, which should meet the requirements of the marking test. Regulation. However, the existing printing process on the surface of the wire core is to spray the inkjet printer ink on the insulation by passing the cross-linked polyethylene cable core through water and cooling it. After printing on the surface of the core, according to the standard test, wipe it w...
