Methyl violet tester: According to the methyl violet test procedure, test and evaluate the thermal stability of nitrocellulose, oxidized gan oil, and nitrocellulose glycol. The instrument can also be used to test high-energy drugsThe thermal stability. This method mainly uses NO2 produced by the decomposition of nitrate esters to evaluate the stability of the tested substance, which is determined by the change in color of the test paper. The testing time starts from the insertion of the sample into the heating module until the color of the test paper changes.

Abel Thermal Stability Tester: Evaluate nitrocellulose fibers according to the Abel test procedurexiao化gan油Nitroglycerin, gun fire yaoThermal stability of energetic materials such as propellants. Heating nitrate ester samples will produce NO2 during decomposition, accompanied by the rapid increase in decomposition rate due to the production of "red smoke" during heating. Determine the appearance of gas decomposition products through the color change of starch iodide test strips. The test result is the time interval from the insertion of the sample into the heating module to the color change of the test paper.

Weiyili Tester: Used for testingFire * yaoThe chemical stability of nitrocellulose and its products can also be tested. Add a quantitative sample to a test tube and heat it under specified conditions to test the heating time required for the litmus paper to turn red or for the sample to release brown smoke, in order to evaluate its chemical stability.

Accelerated aging tester: store explosive samples at high temperatures (usually 50-90 ° C) for a long time, and evaluate changes in sample sensitivity, stability, chemical composition, or mechanical properties during the test period. Used for accelerated (artificial) aging experiments of energetic materials related to chemical stability testing or service life evaluation. Explosive samples will undergo exothermic decomposition during their service life, and the rate of exothermic decomposition is proportional to temperature. Under normal circumstances, the decomposition rate is very low for propellants or propellantsIt usually takes several years to develop to a detectable level. After artificial aging, changes in chemical stability (consumption of stabilizers or antioxidants), external stimuli (collision, friction, electrostatic sparks), or mechanical properties (hardness, compression concentration, dynamic coefficient, glass transition temperature, etc.) can be analyzed.

Bergman Jinke Thermal Stability Tester: Used to evaluate nitrocellulose, smokelessFire * yaoOr the thermal stability of propellants at temperatures of 120 and 132 ℃. The sample will decompose and release a certain amount of gas during the heating process. The gas products will be collected using a glass liquid collection tube and analyzed using an acidity meter.
