Manufacturing method of sound-reducing plastic nitrocotton integrated nail

Abstract

The invention discloses a manufacturing method of a sound-reducing plastic nitrocotton integrated nail. The manufacturing method comprises the following steps that a small particle single-base propellant is prepared by using nitrocotton, aluminum powder, potassium nitrate and a pyrotechnic agent; the prepared small particle single-base propellant is made into a cylindrical tablet-like single-basepropellant with the height of 4.5-5 mm and the diameter of 6-6.5 mm through a tablet making device, and a moisture-proof and environment-friendly paint is sprayed onto the surface of the tablet-like single-base propellant; an embossed nail body and a plastic shell are processed into one body to obtain the plastic integrated nail; and the prepared tablet-like single-base propellant is installed inside the manufactured plastic integrated nail. The manufacturing method greatly reduces various pollutions, and can generate power only by burning. Under the same power level, noise is smaller than that of a conventional nail shooting pill, the abrasion of a used tool is greatly reduced, the operation safety is high, the recoil force is greatly reduced, and the single-base propellant has few ingredients and low price, a technology of rubbing the tip of the nail is adopted, the penetrating power is high, relatively firm is achieved after the nail is hit into a wall, and the sound-reducing plastic nitrocotton integrated nail is not prone to being affected with damp after being stored for a long term in a humid environment.

Description

technical field [0001] The invention relates to the technical field of building installation, in particular to a method for making a sound-reducing plastic nitrocellulose integrated nail. Background technique [0002] At present, the fastening technology of nail-shooting bullets is mainly used in the market. Nail-shooting bullets are extremely dangerous in production, transportation and use, and will produce a large amount of substances that pollute the environment. 2) Double-click dispensing (not only produces a large amount of waste water and heavy metals in the production process, but is also extremely dangerous); 3) Double-base propellant (a flammable and explosive solid propellant); currently, this product has entered the control catalog. [0003] In the past, nail shooting bullets were used as two separate products from nails. They were louder and more abrasive to the tools used. Smoke would be produced during use, and an explosion was required to get power. The operat...

[0003] In the past, nail shooting bullets were used as two separate products from nails. They were louder and more abrasive to the tools used. Smoke would be produced during use, and an explosion was required to get power. The operation safety was not high, it was easily affected by moisture, and the recoil force was relatively high. Large, and the cost is high, and the traditional nail body is smooth, poor firmness into the wall, the nail tip and the overall hardness penetration is not strong, the galvanized layer is thin, and the anti-rust performance is poor
