La description

TNT explosive for coal mine explosion

(1.) TNT is Trinitrotoluenes code
(2.) Molecular Formula: C6H2ï¼ˆNO2ï¼‰3CH3
(3.) Molecular Weight: **7.1.
(4.) Oxygen Balance: **3.9%.
1.Physical Property of TNT:
(5.) Industrial TNT is pale yellow, yellow scaly, and toxic. Its steam and dust
can enter the body through the respiratory tract, the digestive tract and skin contact, but it does not dissolve in water.
(6.) The relative density of solid TNT is 1.*6 g/cm³, bulk density is: crystal (0.9 ~ 1.0) g/cm3, scaly (0.*5 ~ 0.*5) g/cm3.
(7.) Melting point of TNT is *0.0 â„ƒ to *1.8 â„ƒ (pure *1.8 â„ƒ), while the boiling point is **0 â„ƒ (explosion)
2.Chemical Property of TNT:
TNT can be lit by flame, burn stably in the air, and belch black smoke. It will turn to explosion in an airtight condition or burning with a high amount of heap. Please pay special attention to this in production.
TNT explosion characteristics of standard test conditions:
(8) Detonation point: **0 â„ƒ;
(9) Standard drop test (hammer weight *0kg, drop weight *5cm)
(*0) Impact sensitivity: *4.7 N.m.
(*1) Friction sensitivity: 4% ~ 6%.
(*2) Initiation Sensitivity: Minimum detonation dose mercuric fulminate
     is 0.*4 g, DDNP is 0.**3 g.
(*3) Work Capability: The expanding value is (**5 ~ **0) ml.
(*4) Brisance: lead column compression value is *6 mm.
(*5) Detonation velocity: ***0 m/s.
(*6) Specific volume: **0 l/kg;
(*7) Explosion heat: ***0.*4 KJ/mol.
(*8) Explosion temperature: ***7 k.
(*9) Dangerous goods number: ****5.
(*0) UN number: ***9.
(*1) Heat of combustion: ***0.5 KJ/mol.
    Please note: under production condition, the explosion characteristics of TNT has very big change. With the increase of processing temperature, its impact sensitivity increases, such as the melt TNT (*2 â„ƒ ~ **0 â„ƒ), its impact sensitivity is *2% ~ *6%, close to tetryl.
    Besides, TNT in the sunlight or ultraviolet radiation occurs a series of isomerization process. It becomes dark brown, quality declines, sensitivity higher. After **2 hours sunned, TNTs freezing point declines to *6.4 â„ƒ, the impact sensitivity will rise from 4% ~ 8% to *0%, the breaking point is **0 â„ƒ ~ **5 â„ƒ.
