Ramset Gun
A powder-actuated tool (PAT, often generic term, generically called a Hilti gun or a Ramset gun after their manufacturing companies) is a type of nail gun used in construction and manufacturing to join materials to hard substrates such as steel and concrete. Known as ''direct fastening'' or ''explosive fastening'', this technology is powered by a controlled explosion of a small chemical propellant charge, similar to the process that discharges a firearm. Features Powder-actuated tools are often used because of their speed of operation, compared to other processes such as drilling and then installing a threaded fastener. They can more easily be used in narrow or awkward locations, such as installing steel suspension clips into an overhead concrete ceiling. Powder-actuated tools are powered by small explosive cartridges, which are triggered when a firing pin strikes a primer, a sensitive explosive charge in the base of the cartridge. The primer ignites the main charge of powde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powder Actuated Tool
A powder is a dry solid composed of many very fine particles that may Particle-laden flow, flow freely when shaken or tilted. Powders are a special sub-class of granular materials, although the terms ''powder'' and ''granular'' are sometimes used to distinguish separate classes of material. In particular, ''powders'' refer to those granular materials that have the finer grain sizes, and that therefore have a greater tendency to Particle aggregation, form clumps when flowing. ''Granulars'' refer to the coarser granular materials that do not tend to form clumps except when wet. Types Many manufactured goods come in powder form, such as flour, sugar, ground coffee, powdered milk, copy machine toner (printing), toner, gunpowder, cosmetics, cosmetic powders, and some pharmaceuticals. In nature, dust, fine sand and snow, volcanic ash, and the top layer of the lunar regolith are also examples. Because of their importance to industry, medicine and earth science, powders have been stu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
