cell phone jammer is to shield the corresponding cell phone signal

Vacuum evaporation under high vacuum metal is heated so that it melting, evaporation, cooling after the formation of a metal film on the sample surface. Heating the metal: use of resistance heat generated, the use of electron beam. In the implementation of the deposition on the resin, in order to ensure that the metal cools the heat from the resin deformation, evaporation time to adjust. In addition, the melting point, boiling point is too high the metal or alloy is not suitable for the deposition. Vacuum evaporation works. Degreased with acetone or alcohol for cleaning. Surface treatment (if necessary) the corona (the corona) discharge treatment, ultraviolet irradiation treatment. Underside coating / hardening treatment (if necessary). 
The advantage of this method can not only sprayed metal, and metal-ceramic composites can also be sprayed, oxide and carbide. Surface preparation. Because the combination of purely mechanical bond between the plated by metal spraying cover material and substrate material, substrate material must be properly prepared. In order to get a good mechanical bond. Regardless of the surface preparation method, the substrate surface must be clean and no oil pollution. The most commonly used method of surface preparation is sandblasted. , Sand and sharp enough to have a real rough surface, the surface of the cylindrical rotary lathe, effective way is the car a very thick thread, and then gently rolling rolling cutter tooth top.
This paper will these materials the nature of the differences between the various materials to be discussed, in order to enhance the understanding of the mechanism of the injection molding process. Characteristics of crystalline polymers. Many people are familiar with the material crystals, such as edible salt, sugar, quartz, minerals and metals, and of course ice. These solid substances with molecular arrangement and orderly, dense accumulation of features. Other manifestations of the solid material does not form a regular crystal arrangement. They are just cooling a disordered or random molecules, known as the amorphous polymer. Non-crystalline material is not solid, the most common example is the glass, they are just too cold, extremely viscous liquid. (A glass placed a few years, the bottom will gradually thicken, which is caused due to a very slow flow.)  We had to do 3G WCDMA terminal is not a single order or led operators to customize the main but the WCDMA industry chain as a whole do a good job, including a custom operators, including a very customized, that is what we had been considering this year . China Unicom end strategic thinking. Mature WCDMA industry chain advantages, the number of rich terminal section.
