Abstract

The invention aims to provide a van type multifunctional experimental resistance furnace for material thermogravimetric analysis which is economical and practical. The van type multifunctional experimental resistance furnace has heating functions of a common electric furnace and can analyze the quality change of a sample under multi-stage thermal treatment process conditions in real time. By adoption of the technical scheme, the van type multifunctional experimental resistance furnace for material thermogravimetric analysis comprises a hearth, an electronic analytical balance, a temperature controller and a computer, wherein a temperature measuring thermocouple and a fire-resistant container used for accommodating a sample to be analyzed are arranged in the hearth; the fire-resistant container is arranged on an upper base plate; the electronic analytical balance is arranged outside the hearth; a lower base plate is arranged on the electronic analytical balance and is connected with the upper base plate through a supporting rod; the computer is simultaneously connected with the electronic analytical balance and the temperature controller; and the temperature controller is electrically connected with the temperature measuring thermocouple.

Description

technical field [0001] The invention relates to the technical field of resistance furnaces, in particular to a chamber-type multifunctional experimental resistance furnace used for thermogravimetric analysis of materials. Background technique [0002] Experimental electric furnaces are widely used in various laboratories such as materials, metallurgy, chemistry and chemical engineering, biology, and medicine. They are mainly used for heat treatment processes such as drying, calcination, solid-phase synthesis, and crystallization of materials. [0003] In some experiments, it is often necessary to understand the change of the mass of the sample after heat treatment at different temperatures or times, so as to reveal the change law of the material during the heat treatment process. The current method is to take the mass of each sample first, then heat each sample according to the set temperature and time system, and then weigh the sample when the sample is completely coole...
