What is the principle of the improved ceiling nail shooter?

In fact, this "ceiling device" is an improvement of the nail shooter . Its working principle is also relying on the huge thrust generated by the explosion of gunpowder in a closed space to shoot steel nails into the concrete, but it is different from the traditional nail shooter. The big difference lies in its integrated bullet nail and different launching methods. The ceiling nail shooter does not need a trigger, it only needs to exert enough pressure on its top, relying on the reaction force to make the firing needle automatically knock out the projectile in the top launch tube of the ceiling nail shooter , and the huge thrust generated by the gunpowder instantly acts on it . nail behind the plastic pad, pushing the nail to impact on the base. Because the steel hangs on the front end of the integrated nail and the partition between the base body, the kinetic energy of the steel nail is quite buffered when it hits the base body, thereby reducing the damage to the base body caused by the impact, so the hitting effect is similar to that of hammering. Hammer hammer drills and electric hammers will cause less damage to the substrate. Ceiling nail shooting machine is more convenient than traditional nail shooting machine. Because it is mainly used for ceiling fixing projects such as ceilings, bridges, flues, etc., the construction conditions are not restricted, the operation is convenient, the construction efficiency is high, the tensile capacity is strong, and it is stable and reliable. It is called "the ceiling superior device" by many netizens.

The same kind of needle nails are mainly available in flake and powder form on the market. The main component of flake is nitrocellulose . Because it is not sealed, it is easy to cause the firing rate to decrease after long-term storage or damp. The powder type is divided into two types, one is the special formula produced by Nanshan factory, which burns fully and has little residue; the other is ordinary black powder, which contains high sulfur and high residue, which has strong corrosion to the launch tube. Sex. Because the powder type is closed, it is not easy to be affected by moisture and has a high firing rate. The firing rate of the integrated nails produced by Nanshan can reach more than 99%.
