Molten Salt (heat transfer salt)Appearence: white crystalPhysicochemical Parameters (molten salt in common use)ItemindexMelting point142oC-148oCBoiling point680oCDiatexis heat18Kcal/KgSpecific heat0.34 Kal/KgoCThermal expansivity4×10-4/oCCoating temperature620oCAverage thermal conductivity0.317Operating temperature150oC-550oCAppearanceWhite crystalDirection for use:Our company molten salt can be heated directly to make it melted in trough or melted by adding water in supe-high teperature 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 orgnic matter itermingle when being used in high teperature.5, When temperature super 550oC,Molten salt become astable, it begin to react and release gas, mixtures melting point promote, and moten salt degenerate.6,When appear quite a few sediment in high temperature heat carrier, should change heat carrier.Package: in plastic lined woven bags of 25kg/50kgs net each.
