Embodiment 1
[0028] A kind of safe fireworks shell lift-off agent, its formula is as follows:
[0029]
[0030] The nitrogen content of the nitrocellulose in the component is 11%
[0031] A kind of its preparation method of safe type fireworks bomb lift-off agent, comprises the following steps:
[0032] Step 1. After preliminary dehydration of nitrobamboo cellulose, and then forming a layer with a larger surface area on the filter conveyor belt, it is placed in a strong hot air flow environment, driven by the filter screen, on a vacuum filter belt thermal dehydrator Complete the flooding of nitrobamboo cellulose to obtain 75g of water-dispelling nitrobamboo cellulose, and the water content of the nitrobamboo cellulose after water flooding was quickly determined to be 3% by Karl Fischer reagent;
[0033] Step 2: Divide the nitrobamboo cellulose after flooding in step 1 into Group I and Group II according to the mass ratio of 3:10; place 13.3 g of nitrobamboo cellulose in Group I in 50 g...
Embodiment 2
[0040] A kind of safe fireworks shell lift-off agent, its formula is as follows:
[0041]
[0042] The nitrogen content of the nitrocellulose in the component is 12%
[0043] A kind of its preparation method of safe type fireworks bomb lift-off agent, comprises the following steps:
[0044] Step 1. After preliminary dehydration of nitrobamboo cellulose, and then forming a layer with a larger surface area on the filter conveyor belt, it is placed in a strong hot air flow environment, driven by the filter screen, on a vacuum filter belt thermal dehydrator Complete the flooding of nitrobamboo cellulose to obtain 85kg of water-dispelling nitrobamboo cellulose, and the water content of the nitrobamboo cellulose after water flooding was quickly determined to be 2% by Karl Fischer reagent;
[0045] Step 2: Divide the nitrobamboo cellulose after flooding in step 1 into Group I and Group II according to the mass ratio of 2:10; place 14.2 kg of nitrobamboo cellulose in Group I in 40...
