Digital display casting material gas emission tester

Gas generation refers to the amount of gas in milliliters that occurs within a specified time after heating a core sand sample, known as gas generation volume, which can be expressed as milliliters of gas per gram of sample. Another meaning of gas generation is gas generation speed, represented by the relationship curve between gas generation volume and time. The gas evolution of molding materials and mold (core) sand can affect the formation of pores or sand inclusions in castings. Therefore, attention should be paid to controlling the gas evolution of molding materials during casting. In recent years, with the application of chemical binders in the casting industry, it is important to measure the volume and gas evolution rate of gases under specific temperature conditions.

Working Principle:

This instrument mainly consists of a tubular decomposition heating furnace and a system instrument box.

The main structure consists of a temperature control system, a gas generation system, a gas generation display system, etc. The gas generation system uses a single tube high-temperature decomposition resistance furnace with a temperature controller and high-temperature ceramic tubes. The sample is heated to generate gas, which is cooled by the gas chamber and directly read in milliliters by the gas generation display system.
