The invention discloses ramsbottom carbon powder molding adhesive. The ramsbottom carbon powder molding adhesive is prepared by mixing 20 to 30 percent of caustic soda sodium hydroxide solution, 20 to 30 percent of urea solution and 40 to 60 percent of corn starch and adding hot water at the temperature of between 60 and 80 DEG C into the mixture with mixing, wherein the concentration of the sodium hydroxide solution is 0.1 to 5 percent and the concentration of the urea solution is 0.1 to 5 percent. The formula is simple and practical; the materials are easy to obtain; and after the adhesive is used, the ramsbottom carbon powder has good molding, low ash content, good adhesive performance and good chemical activity, has consistent using effect of ramsbottom carbon, reduces the energy waste, avoids environment pollution and provides a guarantee for reducing production cost and promoting benefit.
Description
technical field [0001] The invention relates to the field of calcium carbide production, in particular to a semi-coke powder forming binder. Background technique [0002] With its high fixed carbon, high specific resistance, high chemical activity, low ash, low sulfur and low phosphorus characteristics, semi-coke has gradually replaced metallurgical coke and is widely used in calcium carbide, metal silicon, ferroalloy, ferrosilicon, silicon carbide, chromium Production of iron, fertilizers and other products. However, 30% of coke powder will be produced during production, crushing, transshipment, loading and unloading, and use. Due to its non-bonding and easy pulverization properties, it cannot be fully utilized and can only be used as low-grade fuels such as electric coal and civil use. Therefore, in today's energy shortage, using semi-coke powder to process into pellets instead of semi-coke is the best way to reduce consumption, increase revenue and reduce expenditure in ...
