What is cold paste?

August 04, 2018

Cold paste is a kind of charcoal paste that can be used to build carbon blocks at room temperature. The aggregate used for the production of cold paste is the same as the hot paste, but the production of hot paste uses medium temperature asphalt (softening temperature of 75~95 °C) as the binder, so the construction temperature is high when the carbon block is built, the environmental conditions are poor, labor High intensity. The softening temperature of the binder used in the production of cold paste is only 20 to 25 ° C, and the construction of the carbon block can be carried out at room temperature.
