Problems solved by technology

The existing process does not pay enough attention to the weight change of the finished tablet caused by the fluctuation of the raw material moisture before tableting. The fluctuation of the moisture of the medicine will cause the weight of the finished tablet to fluctuate accordingly, and the weight of the finished tablet will vary greatly, resulting in unstable energy of the tablet. , due to the large difference in the moisture content of the drug material, the shrinkage rate of the tablet varies greatly, resulting in the unstable size of the finished tablet
The above deficiencies all affect the manufacturing process of the tablet, the safety of production and the effectiveness of use.

Abstract

The invention discloses an energy fixation fastener gunpowder flake. The energy fixation fastener gunpowder flake comprises, by weight, 61%-66% of nitrocotton with the nitration degree larger than 201.6 ml/g (N>=12.6%), 0.3%-1.0% of a binder, 0.3%-0.8% of an oxidant, 0.3%-0.8% of a combustion catalyst, 0.7%-1.0% of a stabilizer and the balance ethyl acetate. By selecting the suitable oxidant and catalyst, the effective acting energy and mechanical sensitivity of the energy fixation fastener gunpowder flake are greatly improved, so that the percussion rate reaches 99.9% and the puncture rate reaches 99% or above; meanwhile, by adopting a material prepressing re-granulation and multistage drying process, the particle size of the gunpowder material is selected within the range of 10 mesh-50 mesh, the material preforming moisture is controlled within the range of 6.0%-10.0%, the moisture of the finished energy fixation fastener gunpowder flake is smaller than or equal to 0.7%, the processproduction safety is well guranateed, and the yield of the energy fixation fastener gunpowder flake is increased.

Description

technical field [0001] The invention belongs to the field of fastening equipment in the construction and decoration industry, and in particular relates to a solid-energy nailing tablet and a preparation process thereof. Background technique [0002] The existing formula of the nailing tablet mainly adopts the traditional single-base propellant manufacturing formula as the basic component, such as high-nitrogen nitrocellulose, plasticizer alcohol ether solvent or ethyl acetate, and an appropriate amount of adhesive and stabilizer , compressed into cylindrical tablets of different heights. Another example is the patent application number 201811000706.2 "A High Thrust Nail Shooting Tablet". The tablet made of this formula has the advantages of energy saving, labor saving, and no need for electricity. However, the burning rate of this kind of nail-shooting tablets is similar to that of single-base propellants, and the gas volume generated by instant combustion is relatively sma...
