Problems solved by technology

Its main disadvantage is: the percussion agent is a highly sensitive chemical, because the use of the percussion agent, in the process of manufacturing, storing and transporting the nail shooting ammunition, if the operation is not careful or there is a collision, an explosion accident may occur; The use of copper as shells is a complex process and high cost; copper shells are inevitably scattered during the recycling process, which will cause waste of copper materials. In addition, scattered copper shells will react chemically when they encounter water, acid, alkali and other substances. , causing environmental pollution
[0005] The second type uses methyl cellulose as the non-percussive powder shellless nail bullet that is made of binder. It is made by mixing nitrocellulose with binder, and the process of making binder is complicated, requiring methylcellulose, Boiled water, ice water and ice cubes, etc.; and because methylcellulose contains starch, it is easy to absorb moisture. In the indoor environment in the south, the maximum moisture absorption can reach more than 10% of its own weight, but when the moisture content reaches 3%, it cannot use

Embodiment 1

[0035] Weigh 1Kg of nitrocellulose with a nitrogen content of 11.9% to 13.5% and pour it into the kneader; weigh 10g of diphenylamine and 550g of ethyl acetate, stir and dissolve the diphenylamine into the ethyl acetate solution, and add 50-100g after it is completely dissolved Ethanol solvent; start the kneader and slowly pour the solvent dissolved in diphenyl gum into the nitrocellulose for stirring and gelation; add 5-7g of chemical pigment according to the required color after ten minutes; continue stirring for 20 minutes before gelation Form small granules; pour the small granules into a baking tray, dry to a moisture content of about 5%, press them into the desired shape with a tablet press or extrude the small granules with an extruder and cut them into the desired shape ; The above-made nail-shooting bombs are dried to a water content below 1.5%. The nail shooting bullets made above can be used directly, or can be coated with a layer of waterproof glue on the outer sur...

Embodiment 2

[0037] Weigh 1Kg of nitrocellulose with a nitrogen content of 11.9% to 13.5% and pour it into the kneader; weigh 10g of diphenylamine and 550g of acetone, stir and dissolve the diphenylamine into the acetone solution, and add 50-100g of ethanol solvent after it is completely dissolved; start The kneader slowly pours the solvent dissolved in diphenyl gum into the nitrocellulose for stirring and gelation; after ten minutes, add 5-7g of chemical pigment according to the required color; continue to stir for twenty minutes and then gel to form small particles; Pour the small granules into a baking tray, dry them to about 5% water content, press them into the desired shape with a tablet machine or extrude the small granules with an extruder and cut them into the desired shape; The finished nail bullet is dried to a moisture content below 1.5%. The above-made nail shooting bullets can be used directly, and can also be covered with a layer of waterproof glue on the outer surface of th...

Abstract

A non-shell jet nail bullet is made up of mitrocellulose, stabilizer, solvent and chemical pigment through dissolving the stabilizer in solvent, kneading it with nitrocellulose, colloidizing, adding chemical pigment, stirring while granulating, backing and die pressing.

Description

technical field [0001] The invention relates to a nail-shooting bullet and a manufacturing method thereof, in particular to a nail-shooting bullet without firing charge and caseless and a manufacturing method thereof under normal temperature and pressure. Background technique [0002] Nail fastening technology is widely used in construction installation, decoration, shipbuilding and other industries. The nail bullet is an essential energy part of the nail fastening technology. At present, there are two main categories of nail-shooting bullets: the first category is copper shell nail-shooting bullets widely used at present; No. 97117629 patent discloses exactly this nail shooting bullet and its manufacture method. [0003] Both types of nail-shooting bullets currently have certain defects: [0004] Copper shell nail bullets are mainly composed of copper shell, propellant powder and percussion powder. Its main disadvantage is: the percussion agent is a highly sensitive che...
