The insulation feature of cell phone jammer can better ensure thesafety and security

Profiles by the oil after the first etching, after alkaline etching, the light, before the completion of processing. The process is the core process is the etching, by etching the decision to the mechanical pattern, sand. The biggest advantage is that different from the alkaline etching, acid etching to mechanical pattern capability, from the sand, aluminum consumption is low, generally 3-5 minutes to complete, aluminum consumption is almost 1/8-1/6 of the alkaline etching. Efficiency and resource conservation point of view, the etching is undoubtedly a big step forward in the alkaline etching process. However, the etching of the more prominent environmental problems: acid tank escape of toxic gas HF wash tank F ˉ pollution. The fluorides are generally highly toxic, processing more difficult. In addition, the etching profile appearance of hair black hair and dark, despite the forced continuation of the alkaline etching and light can brighten some. The antenna of  cell phone jammer is the internal and built in type.
But still very dark, not only increasing the process, and has since lost its luster, these problems has not yet effective solution. The polishing process: degreasing → washing → polishing → washing → washing → oxide composition profiles into the polishing tank after by degreasing, can be formed after 2-5 minutes polishing the mirror, washing after direct oxidation. The process is the core process is the polishing, and go pattern, mirror polished groove. Polishing advantages of aluminum consumption is low, light profiles, but the polishing tank NOx escape, resulting in serious bodily harm of environmental pollution and operatives, and the same time, expensive chemical raw materials costs and other factors also restricted the promotion of the process. More working efficiency of the antenna and host of  cell phone jammer  can be ensured.
Throughout these three processes, although with different characteristics, but the disadvantage is more prominent, such as alkaline corrosion of aluminum consumption, caustic sludge, low efficiency; etching fluoride pollution, profiles, dark; polish pollution is serious, the cost is too high. These processes or pollution of the environment, or a waste of aluminum resources, or reduce the quality of the aluminum surface in urgent need of process improvement "FRP" is the name of China, foreign countries known as the "glass fiber reinforced plastics using the abbreviated letters of the alphabet FRP FRP is essentially a fiber reinforced plastic. With glass fiber reinforced thermoplastic resin, called thermoplastic glass fiber reinforced plastic, using letters of the alphabet FRTP; glass fiber reinforced thermosetting resin called thermoset glass fiber reinforced plastic, that is often said that the FRP. The antenna of this kind of  cell phone jammer is the omnidirectional type.
The production of glass fiber reinforced plastic is thermosetting terms of FRP have the following characteristics. Advantages: (1) lightweight, high strength, good corrosion resistance (2) (3) good electrical properties (4) good thermal properties (5) (6) can be designed to process quality shortcomings: (1) low modulus of elasticity ( 2) Long-term temperature resistance (3) aging (4) interlaminar shear strength of the world's most frequently used forming methods have the following four. ① hand lay-up method: The main use of state of Norway, Japan, the United Kingdom, Denmark. ② injection method: The main use of state of Sweden, the United States, Norway. ③ molding method: The main use of the country such as Germany. ④ the FTM method: The main use of state of the United States and Europe, Japan.
