Problems solved by technology

At present, among the instruments and equipment used to detect the oxidation of dangerous solids, many manual operations are used. On the one hand, it causes many safety hazards in the experimental process and endangers the personal health of the experimental operators. On the other hand, the obtained data is not scientific enough. Accurate, the technical requirements on the ignition temperature of the ignition device, the heating power of the sample, and the time measurement cannot meet the requirements in the "United Nations Recommendations on the Transport of Goods-Tests and Standards Manual" in the measurement method of dangerous goods solid oxidation

Embodiment 1

[0100] The preparation of embodiment 1 reference material Potassium bromate and dry cellulose silk

[0101] Select 3000 g of dry cellulose filaments with a length in the range of 50 μm to 250 μm and an average diameter of 25 μm, dry the selected dry cellulose filaments at a temperature of 105° C. for 6 hours to a constant weight, cool them for use, and test , the water content in the dry cellulose silk is 0.3%.

[0102] Commercially pure potassium bromate is sieved but not ground, and 1000 g of potassium bromate with a particle size of 0.15 mm to 0.3 mm is selected, dried at 65° C. for 12 hours to a constant weight, and cooled for later use.

Embodiment 2

[0103] Embodiment 2 Inspection of sample to be tested

[0104] Check whether the sodium nitrate to be tested contains particles with a diameter of less than 500 μm. If the particles with a diameter of less than 500 μm account for more than 10% of the total weight, or the substance is fragile, all the particles to be tested should be removed before the test. The sample is ground into powder.

Embodiment 3

[0105] The mixing of embodiment 3 potassium bromate and dry cellulose silk

[0106] Weigh 30g of potassium bromate and 210g of dry cellulose silk according to the mass ratio of 3:7 and mix them in a mechanical mixer to obtain fully mixed mixture 1.

Abstract

The present invention provides a hazardous material solid oxidation property detection apparatus and a method for detecting the hazardous material solid oxidation property by using the detection apparatus. The hazardous material solid oxidation property detection apparatus comprises a lifting rod, a metal wire ignition line fixed on the lifting rod, a heating controller of the metal wire ignition line, a lifting rod controller for controlling the lifting of the lifting rod, a sample production device for making a detected sample form a certain shape, and a heat resistance plate for placing the detected sample. With the hazardous material solid oxidation property detection apparatus of the present invention, the oxidation property of the hazardous material solid to be detected can be scientifically, efficiently and accurately determined, the selective suitable packages can be classified, the experiment operation is safe, and the personnel health of the experiment operator can not be hazarded.

Description

technical field [0001] The invention relates to a dangerous goods detection device, in particular to a dangerous goods solid oxidation detection device. Background technique [0002] Dangerous goods are international compulsory inspection commodities. If they are not handled properly during production, packaging, storage and transportation, accidents such as combustion, explosion, corrosion, and poisoning are likely to occur, causing harm to the environment and human health. Dangerous solids with oxidizing properties have the potential to significantly increase the burning speed or burning intensity of combustible substances when mixed with combustible substances, or may form spontaneously ignitable mixtures when mixed with combustible substances. Hazardous chemicals, whether dangerous solids are oxidizable is an important indicator that needs to be determined in production, transportation and storage. Relevant test methods have been formulated at home and abroad to determin...
