Molten salt

Molten Salt is a kind of chemical reaction heat-conducting medium which is formed by mixed molten salt,also named heat transfer salt,heat transfer medium. With the increased use of high-temperature operations,the chemical and petroleum process industries need an economical,efficient,heat transfer medium that is between steam and direct-fire heating. To help this need,the Weifang Changsheng Nitrate Co., Ltd. offers molten salt. This product is a heat transfer medium for heating and cooling between 130-1000°C. Molten salt is used because it has low melting point, high heat transfer coefficient,thermal stability,and low cost. It is nonfouling-a commonly recognized defect of many organic heat transfer media. Molten salt is nonflammable,nonexplosive and evolves no toxic vapors under recommended conditions of use. Our company is the only professional manufacturer producing molten salt, our molten salt production and processing, inspection and good use of technology is very mature . We have customers across the country, including many large state-owned enterprises which purchase technology and equipment from Germany and Japan, the earliest users has over 15 years. Our product is high quality and can meet the needs of market. While providing technical services,we can adjust production formula to meet customer’s demand. Physicochemical Parameters (molten salt in common use) Item index Melting point 142°C-148°C Boiling point 680°C Fusion-thermal 18Kcal/Kg Specific heat 0.34 Kal/Kg°C Thermal expansivity coefficient 4×10-4/°C Coating temperature 620°C Average thermal conductivity coefficient 0.317 Using temperature 150°C-550°C Appearance White crystal Direction for use: Our company molten salt can be heated directly to make it melted in trough or melted by adding water in supe-high temperature carrier. Being melted to such a degree to be able to circulate ,then being sent to heat-carrying furnace to reach target temperature.. Matters need attention: 1, Molten salt should be kept clean, do not able to mix with organic such as charcoal, rosin, reducing substances etc, to avoid arousing fierce chemical reaction. 2, At the beginning of heating, controlling heat-up speed strictly, to avoid system heat shock. 3,Keep flowrate of heat cycling steady, forbid temperature higher than Coating temperature. 4,Forbid water and organic matter intermingle when being used in high temperature. 5, When temperature super 550°C,Molten salt become astable, it begin to react and release gas, mixture’s melting point promote, and molten salt degenerate. 6,When appear quite a few sediment in high temperature heat carrier, should change heat carrier.
