Abstract

The present invention provides a thermal analysis device with extremely fast temperature rise-variable atmosphere-real-time weight and its application, including a furnace reaction device, a fixed protection device, a sample weighing device and an electric control device; wherein the sample weighing device uses pressure The sensor replaces the traditional thermobalance, combined with the moving furnace body, to realize the measurement of the macroscopic sample amount (g-kg level), and avoids the quality error caused by the vibration of the moving measurement object, and at the same time uses corrosion-resistant materials to break through the thermobalance. Limitations caused by corrosion; can realize any combination of various combustion atmospheres and extremely rapid temperature rise, greatly improving the scope of application; can accurately measure the amount of thermal cracking of samples, providing an effective way for the study of thermal cracking behavior in the later stage.

Description

technical field

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

[0002] A thermal analyzer is an instrument for thermogravimetric analysis and thermogravimetric differential measurement of a sample. The general thermogravimetric analyzers on the market are all small in size, have high precision requirements, and measure a small amount of samples. At present, the thermogravimetric analysis of the "large sample" with large size and mass can only characterize its overall reaction by the quality 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 limitation of sample size and the limitation of existing thermogravimetric analyzers for harsh use environments, thermogravimetric analyzers can ...
