Sal fundida
Physical and chemical properties:
Melting being that salt melts formation experiences and observes fused salt,is the body melt from the ion that the positive ion and the negative ion are composed of.Fused salt is a compound from potassium nitrate,nitrous acid sodium nitrate composition.
As a new type of heat carrier, molten salt has the advantages of high heat transfer coefficient, good thermal stability, long service cycle, low cost, reliable safety performance and so on. It is also an excellent substitute for heat conduction oil.
Solicitud:
Good heat passage medium,applies to petrochemical industry,and heat treatment industry broadly.As having melting point with heat carrier,conducting heat low,is efficient,heat passage is stable,safety is innocuous,use the temperature to be able to be accuracy control,be suitable to large-scalethermal conversion and thermal transmission,but replace steam and heat conduction oil specially.

Instructions for use:
Heat transfer molten salt can be heated directly to make it melted in trough or melted by adding water in super-high temperature carrier. Being melted to such a degree to be able to circulate ,then send it to heat-carrying furnace to reach target temperature.
Notice:
1. Molten salt should be kept clean, do not allow 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 temperature unstable.
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 teperature.
5.When temperature exceed 550℃,Molten salt become unstable, it begin to react and release gas, molten salt’s melting point promote, and make moten salt degenerate.
6.When appear quite a lot sediment in heat medium molten salt, should renewal the old molten salt.
7.Before stop working, all molten salt must be sent back to store molten salt trough,then engine can be cut off.
