An experimental device for the research of thermogravimetry and gas production characteristics of gram-level materials

Abstract

The invention discloses a gram-grade material thermo-gravimetry and gas production property research experimental apparatus. The experimental apparatus comprises a console, an electronic scale, a heating furnace for heating a detected sample, a crucible for holding the detected sample, and a lifting supporting frame for supporting the electronic scale, wherein the heating furnace is fixed on the side of the console; the lifting supporting frame is of a gamma-shaped structure and is composed of a vertical bracket and a horizontal supporting plate; the bottom end of the vertical bracket of the lifting supporting frame is connected and arranged on a driving motor in the console; the electronic scale is located above the heating furnace and is arranged on the upper surface of the horizontal supporting plate of the lifting supporting frame; a reaction pipe is connected below the horizontal supporting plate of the lifting supporting frame through a fixing frame; the crucible is arranged in the reaction pipe, and is connected to a spring piece of the electronic scale through a metal wire hook which runs through the horizontal supporting plate of the lifting supporting frame. The experimental apparatus disclosed by the invention can test a great amount of samples (the scale is 0-110g in measuring range and is 0.1mg in precision), and can implement thermo-gravimetry and gas production property research on the tested samples under an instantaneous warming state.

Description

technical field [0001] The invention relates to an experimental device. In particular, it relates to an experimental device for researching thermogravimetry and gas production characteristics of gram-level materials. Background technique [0002] Thermogravimetric analysis is a technique for measuring the relationship between mass and temperature of a substance under program-controlled temperature, and is a common method for studying the kinetic characteristics of fuel combustion and pyrolysis. The instrument usually used for thermogravimetry is a thermobalance. Generally, a thermobalance can only study about 10mg of materials, and the largest one is only about 20mg. This sample weight range has strong advantages for the measurement and analysis of single component materials. However, the milligram-level measurement range is difficult to meet the gravimetric requirements of thermogravimetric analysis of multi-component materials, so it is difficult to fully reveal the inte...
