The effect of adding carbon black to HDPE anti-seepage geomembrane

2020-04-09

In some waterproofing layer engineering projects, carbon black is added to the material of HDPE anti-seepage geomembrane. So what is carbon black? Carbon black is an amorphous carbon, and its appearance is qualitatively analyzed as light and fire evacuated ultra-fine gray black particles. The bulk density is large. It is a substance containing carbon content that is burned or decomposed by ethanol. Carbon black particles are not isolated and helpless. Generally, a plurality of particles intersect with each other according to the carbon crystal layer to produce block polymerizations with certain shapes and different specifications. Its functionality is expressed by the level of aggregation of carbon black particles into chains or dendrites. The higher the functionality of carbon black, the more three-dimensional perforations will occur. Carbon black has the practical effects of light absorption and reverse transmission. It also has the characteristics of high temperature resistance, light resistance, and chemical resistance. It can be used as a dye for coloring. It can also be used for vulcanized rubber reinforcement and light stabilizers. HDPE anti-seepage geomembrane plus such chemicals can alleviate the embrittlement of the anti-seepage geomembrane and increase the service life.
