The Researching Of No Corrosin, Micro Smoke And Residual Powder Loads

The paper is mainly research the firing mechanism, combustion performance of explosive propellant and the response of the powder loads, seeking for the key to the situation of smog, residual and corrosion of powder loads.The paper through researching the primer mixture difference, medicament size, granularity proportion, drugs manufacture and charge methods; researching the different component of explosive propellant, medicament proportion, medicine grain shape, medicament size, and these factors influence on the combustion performance; charging powder in different cartridge case, using different guns to make the firing experiment and inspection the test results.Using the trinitrotoluene lead phenate, tetrazene, glass dust, barium nitrate, lead peroxide, according to specific proportion to mix. The misfire rate of primer mixture using dry process is low and easy to press explodes. If we using the wet method to mix and using the revolving way to charge, the rate of fire will be raised and the smog, residual and corrosion will be reduced.Select the cellulose nitrate with high content of Nitrogen, adjust the allocated proportion of cellulose nitrate and nitroglycerine, make the explosive propellant with high energy, reduce the using of active material and difficult to decompose material, we can get the needs energy of powder loads. Select the laminated shape powder among 40 to 100 items, charging into appropriate type cartridge cases, we can get the different might of different cartridge type, we can often solute the not burnt completely simultaneously.Using the barium nitrate. lead peroxide as oxidant instead of the potassium chlorate to Solute the corrosion for the bore of gun.Using the test results to charge, we can solute the smog, residual and corrosion of powder loads after firing.
