Example Embodiment
[0060] Example 1:
[0061] Based on the total feeding amount, measure 30 parts by weight of deionized water or distilled water, heat to 90°C, add 30 parts by weight of potassium nitrate to it, stir to dissolve it; pour it into the kneader, turn on the stirring, and then add 10 parts by weight of potassium perchlorate, stir for about 5min-10min, and then add 5 parts by weight of sodium carboxymethyl cellulose, add slowly, the adding process should be slow, the addition should be uniform, to avoid the caking of sodium carboxymethyl cellulose; add 5 Parts by weight of silicon powder, 20 parts by weight of guanidine nitrate, 30 parts by weight of nitroguanidine, knead for at least 1 hour at room temperature to make the components uniformly mixed.
[0062] Note: When starting to add flammable agent, you must stop the machine to add the material, and wait for the personnel to return to a safe position before starting to stir.
[0063] Sampling and analyzing the moisture, if it is too high...
Example Embodiment
[0065] Example 2:
[0066] Assuming that the standard of the total feeding amount is 100 parts, measure 30 parts by weight of deionized water or distilled water, heat to 90°C, add 17 parts by weight of potassium nitrate to it, stir and dissolve it; pour the solution into the kneader and stir , Then add 6 parts by weight of potassium perchlorate, stir for about 5min-10min, then add 5 parts by weight of sodium carboxymethyl cellulose, add slowly, the adding process should be slow, the addition should be uniform, to avoid the caking of sodium carboxymethyl cellulose ; Add 42 parts by weight of guanidine nitrate, 30 parts by weight of nitroguanidine, knead and mix at room temperature for at least 1h to make the components evenly mixed.
[0067] The rest of the operation is the same as in Example 1.
Example Embodiment
[0068] Example 3:
[0069] Suppose the standard of the total feeding amount is 100 parts, select carboxymethyl cellulose with a viscosity of not more than 100mPa·s, add 43 parts of deionized water or distilled water, heat to 90°C, and add 21 parts by weight of potassium nitrate to it, Stir and dissolve; pour the solution into the kneader, stir, then add 6 parts by weight of potassium perchlorate, stir for about 5-10 minutes, and then add 5 parts by weight of sodium carboxymethyl cellulose, slowly add, the adding process should be slow, The feed should be uniform to avoid agglomeration of sodium carboxymethyl cellulose; add 3 parts by weight of silicon powder, 37 parts by weight of guanidine nitrate, 28 parts by weight of nitroguanidine, and knead at room temperature for at least 1 hour to make the components evenly mixed .
[0070] The rest of the operation is the same as in Example 1.
