Fire-fighting measures: In case of high fever, increased pressure within containers, cracking and the risk of explosion. Hazardous combustion products: nitrogen. Fire fighting methods: This product is flammable. Try to move containers from the scene empty Department. Water cooling containers to keep the fire until the end of fire cooling containers to keep the fire with water spray. Liquid nitrogen can be used to accelerate the evaporation of water spray mist, but can not use water cannon to shoot liquid nitrogen. Physical and chemical properties of nitrogen: 1. Under normal temperature and pressure, nitrogen is a colorless, odorless and tasteless inert gas. Accounting for 78.1 percent of nitrogen in the air. Liquid nitrogen is a colorless, odorless, lighter than water. Do not burn in air. Inert at room temperature, but at high temperature and pressure with a catalyst when ammonia and cyanide. 2. The available reactive nitrogen discharge pressure. In the high-temperature synthesis and metal nitrides (Mg3N2, Cu3N2 etc.). In 1000 ℃ and calcium carbide reacts ammonia clear. 3. Slightly soluble in water, alcohol and ether. At 25 ℃, when the solubility 101.325kpa in methanol was 16.45mL / 100mL, in ethanol as 14.89mL / 100mL, in ether was 29.30mL / 100mL, solubility in water is 0.02354mL / g (0 ℃), 0.01258mL / g (30 ℃), 0.01023mL / g (60 ℃). 4. molecular nitrogen is 28.0134, the melting point (triple point of high purity nitrogen industry, 12.53kPa) is -210.0 ℃ Shandong high purity nitrogen, liquid density (-210.0 ℃, 12.534kPa) was 869.5kg / m3, thermal conductivity (100kPa , 280K) is 0.02447W / (MK) Fire-fighting measures: In case of high fever, increased pressure within the vessel, high purity nitrogen, cracking and the risk of explosion. Hazardous combustion products: nitrogen. Fire fighting methods: This product is flammable. Try to move containers from the scene empty Department. Water cooling containers to keep the fire until the end of fire cooling containers to keep the fire with water spray. Liquid nitrogen can be used to accelerate the evaporation of water spray mist, but can not use water cannon to shoot liquid nitrogen. Shandong high-purity nitrogen, high purity nitrogen _ _ Fung Ltd.
