The development of communication energy has promoted the great development of cable industry. Because the plastic itself has the advantages of good electrical insulation, superior mechanical properties, chemical corrosion resistance, easy processing and low cost, it has been widely used in the cable processing industry.
When the cable color masterbatch is used in the city communication cable, it has a certain control on the number of electric sparks of the cable during high-speed extrusion (1-2 / 22 km), in order to ensure the call quality of the communication cable.
The high number of electric sparks when the cable color masterbatch is used in high speed extrusion is mainly due to the following factors:
(1)The pigment particles in the color masterbatch are too large;
(2) The molecular weight distribution of the carrier in the color masterbatch is too wide, and a small amount of molecular weight is too high to cause poor dispersion;
(3) The raw materials in the color masterbatch have impurities and have not been filtered out;
(4) The color masterbatch is not well kept in the process of storage and is contaminated by dust;
(5)The water content of color masterbatch is too high.
The pigments produced and exported by Colorchem Company can well meet the production requirements of high quality color masterbatch and provide guarantee for cable processing.
