Problems solved by technology

However, the test device in this method cannot separate the test system from the measurement system. The heat generated by the reaction during the test will affect the balance measurement, and the large weight of the test system itself limits the use of a large range and low-precision balance for measurement.

Abstract

The invention relates to an improved test device for testing an oxidizing solid. The improved test device is provided with a test system and a measurement system and is characterized in that the test system and the measurement system are positioned at two ends of a lever system and are connected with each other through the lever system; the test system comprises a bracket A, a limiting block, a tray A, a heat isolation plate, a wiring post and a resistance wire; the lever system comprises a lever, a wire A, a wire B, an electric brush, a current collection ring, a bracket B and a power supply; the measurement system comprises a balance weight, a tray B, a level adjuster and a balancer. Compared with the prior art, the improved test device disclosed by the invention has the advantages that the test system can be separated from the measurement system, the measurement precision is improved according to an equal arm lever principle, and damage of heat and dust on the balancer during combustion can be eliminated.

Description

technical field [0001] The invention relates to an oxidizing solid testing device, in particular to an improved testing device for testing oxidizing solids which can separate the testing system from the measuring system, has high measurement precision, is safe and reliable. Background technique [0002] An oxidizing substance is a substance that does not necessarily burn itself, but usually may cause or promote the combustion of other oxidizing substances due to the release of oxygen. It belongs to category 5 in the classification of hazardous chemicals. The hazards of oxidizing substances are multifaceted. Therefore, before storage and transportation, oxidizing substances must be identified and further classified to assess their hazards. At present, the latest oxidizing solid test methods and devices used at home and abroad refer to Supplement 2 of the fifth edition of the "Recommendations on the Transport of Dangerous Goods Manual of Tests and Criteria" which is in charge ...
