High quality supply BGD238 closed flash point tester

BGD 238 Closed Flash Point Tester

There are two methods for determining the flash point: the open cup method and the closed cup method. The flash point determined by the open cup method is 15-25 ℃ higher than that determined by the closed cup method. The high or low flash point is related to the molecular composition of the oil and the pressure on the oil surface. The higher the pressure, the higher the flash point. Flash point is an important indicator for preventing oil fires. In an open container, the heating temperature of the oil should be 10 ℃ lower than the flash point; Heating in pressure vessels does not have this restriction.

The flash point of chemical products is an important indicator of their safety performance under conditions such as use, storage, and transportation. Therefore, it is essential for many coating manufacturers to know the flash point of their products.

By controlling the flow rate of combustible liquids to ensure stable flames and adjustable size, this method avoids the danger and inconvenience caused by electronic ignition and liquefied gas ignition.

BGD 238 Closed Flash Point Tester

Explanation: The concentration of vapor evaporated from the surface of flammable and combustible liquids (including solids with sublimation properties) increases with increasing temperature. These vapors form a mixed gas with air. When the mixed steam reaches a certain concentration, if it comes into contact with a fire source, it will produce a flash off instantaneous combustion, which is called flash ignition. The lowest temperature at which a solid undergoes flash ignition is called the flash point.
