Abstract

The invention provides a rapid heating-atmosphere variable-weight real-time thermal analysis device and application. The thermal analysis device comprises a furnace body reaction device, a fixed protection device, a sample weighing device and an electric control device, wherein a pressure sensor is used for replacing a traditional thermobalance in the sample weighing device; so that measurement of the macroscopic sample amount (g-kg level) is achieved in combination with a movable furnace body, and mass errors caused by vibration generated by moving a measured object are avoided; meanwhile, the limitation caused by the fact that the thermobalance is prone to being corroded is overcome by adopting a corrosion-resistant material; so that any combination of various combustion atmospheres and top-speed temperature rise can be realized, and the application range is greatly widened; therefore, the thermal burst amount of the sample can be accurately measured, and an effective way is provided for the research of the later thermal burst behavior.

Description

technical field

[0001] The invention relates to the field of heating experiment equipment, in particular to a thermal analysis device and application of extremely rapid temperature rise-variable atmosphere-weight real-time. Background technique

[0002] Thermal analyzer is an instrument for thermogravimetric analysis and thermogravimetric differential measurement of samples. The general thermogravimetric analyzers on the market are small in size, require high precision, and measure a small amount of samples. Most of their measuring ranges are ≤100mg, which cannot meet the test requirements of large sample sizes. At present, the thermogravimetric analysis of a "big sample" with a large size and mass can only characterize its overall reaction through the mass difference before and after heating in the tube furnace, but cannot understand its real-time reaction during the heating process. There are certain limitations. Due to the restriction of the sample size and the limitati...
