What is the role of ordinary charcoalCharcoal residue of jujube wood
Agricultural fieldTo improve the ground temperature: the soil after the application of carbon powder, as the black carbon particles absorb solar heat, soil temperature can increase a few degrees Celsius, promote seed germination, in particular, can promote the germination of seeds not easy to germinate, improve germination rateSoil improvement: applying carbon powder in the soil, can generate root grain bacteria on the carbon surface, thus forming the agricultural soil for plant cultivation, the so-called "continuous cropping obstacle". And the carbon on the grains, beans and vegetables grow, color and taste.Keep moisture, carbon in the relative humidity is 50%, can quickly absorb about 20% of the water, can be used to maintain soil moisture. It also can improve the permeability of soil and water, to provide a good living space for the benefit of plant microbe.
chemical industryAll requirements of high surface hardness and wear resistance, and the center of all steel products with good toughness to carburizing. Used to carburizing steel containing carbon compounds known as carburizing agent. Charcoal as raw materials, add a certain amount of contact agent, made of carburizing agent.Charcoal is the best raw material for the production of carbon disulfide, used to manufacture carbon disulfide charcoal, should be hard, volume, ash and moisture content is small, fixed carbon content is high
Industrial field1 metallurgical industryThe charcoal smelting pig iron generally has the fine grain structure, the casting is close, does not have the crack the characteristic, uses the charcoal production pig iron to contain the impurity to be few, is suitable for the production high quality steelIn the production of nonferrous metals, charcoal is often used as surface flux, which can not only reduce the spatter loss of molten metal, but also reduce the gas saturation in the meltA large amount of charcoal is also used to produce crystalline silicon, but the production of crystal silicon with charcoal ash should not contain carbon head and too much.
