Detailed Description

The energy source used to drive a powder actuated fastener into the base material is a self contained unit called a powder load. Specific load types are designed for each unique powder actuated tool. Powers tools use cased powder loads in which the propellant is housed in a crimped metal case. 1.Powder Load Identification In the commercial market, cased powder loads are available in sizes ranging from .22 to .27 calibers. The power level or strength of a cased powder load is identified using a 12 level system in which a combination of six color codes and two case types are used. Power level 1/gray is the lowest with power level 12/purple being the highest. Only six color codes are used because there are not twelve easily distinguished colors available. The following table shows this identification system. Powder loads are available as single units for single shot tools and collated in groups of 10 into plastic strips or metal discs for semi-automatic tools. Powers tools use .22 caliber A, .25 caliber, and .27 caliber crimped, rim fire powder loads having power levels ranging from 1-6. Powder loads for other commercially available tools are also available such as .22 caliber Ladd and .27 caliber long. Consult the individual tool instructions for details on the caliber, range, and type of load. The crimped tip on the load retains the powder in the casing. Wadded loads which have a plug in the front of the casing should never be used in tools designed for use with crimped loads such as low velocity, piston tools. The wadding material can cause the tool to clog or jam. Rim fire refers to the method of actuation. In a rim fire powder load, the primer is contained in the rim of the casing. When the tool is fired, the firing pin strikes the rim 2.Powder Load Selection Use of the proper power level is critical to the success of a powder actuated fastening. Prior to selecting the proper power level, conduct a center punch test as described in the upcoming section on base material suitability. To select the proper power level to be used with a specific fastener, always make a test firing using the lowest power level recommended for the tool being used. On tools which have a variable power control, use the lowest possible setting. If the lowest power level does not fully drive the fastener, try a powder load having the next higher power level. Continue this procedure until the proper fastener penetration is obtained. 3.Our Prodcut Our product divides into five kind of specifications:S1,S2,S3,S4,S5, each kind ofspecification divides into several kind of different might, spreads onthe color and the packing color code discrimination by the productforehead.
