Cell phone jammer company has enhanced the training mechanism

Guanyu     cell phone jammer       company has been continuously introducing high-quality talents. In addition, the zinc coating materials used at the factory are usually passivated with polymer coating, this coating is insulated, if you use less pressure conductive gasket is almost impossible to implement the RF overlap, but also mechanical design will increase the difficulty of the chassis. So it is best to draw the necessary power in the steel passivation polymers issues related to many users, suppliers and metal processing enterprises, just think of metal passivation is necessary, even if the product has not proposed drawings This requirement should also be handled. The metal surface with a conductive and sometimes there is no benefit, and some metal processing companies do not really understand this, but only assuming the metal to polymer passivation. If the metal processing sector with a traditional "yellow passivation" treatment, these processing can be seen clearly, but if they are using a transparent polymer, it is difficult with the naked eye or hand-contact manner with no surface treatment of metals celebrate separately. Guanyu    cell phone jammer company has enhanced the training mechanism.Many product manufacturers will face the problem of poor shielding effect, until they found that the surface of bright metal parts Walled In fact, a layer of insulating passivation layer. Sometimes, though some users are obtained for several consecutive years very bright polished surface of metal parts, but they may start suddenly one day had received the polymer surface passivation of metal parts, and without any advance notice.
The surface is also more likely to leave scratches, so usually the need for aluminum, zinc alloy castings for chromium (trivalent) salts or similar process passivation treatment, aluminum and magnesium castings are required for such treatment even if EMC does not take into account factors (high EMC performance in the pursuit of the occasion, requiring shielded enclosure must be made of metal casting or milling parts), relative to the sheet metal chassis, metal casting or milling parts made up of chassis assembly more efficient, and part of the material and help reduce tooling costs arising. Products from Guanyu     cell phone jammer company have extended over the main developed cities and key districts.do Gok 0 dine), chromate passivation (Iridite), Oakite handling and processing are commonly used tinned high conductivity passivation process, After the treated metal has a higher reflection properties, help to enhance the effect of RF overlap to get a good shielding effectiveness. Which require individual treatment process used hexavalent chromium, which is banned in the EU the use of this material (2002195/EC), so the trivalent chromium and other chemical raw materials is gradually applied. Tin-plated aluminum can to the surface, so that it can adapt to soldering, or reduce the contact surface of the electrolytic potential (such as steel or copper with tin) to reduce the galvanic corrosion effect. Good conductivity of low carbon steel, the relative permeability is also large, low-frequency magnetic field shielding effect is good. Products from Guanyu     cell phone jammer       firm are sold to southeast Asia, Europe and America.Steel chassis wall surface oxidation (rust), to get the desired effect of RF overlap, need to be tinned or galvanized. Zinc-plated steel surfaces help to improve the EMC performance of products. There are two ways of tin plating, respectively, showing bright matte surface and the surface, matte coating is more conducive to the EMC performance of products, but also easy to implement RF overlap and welding. The conductivity of zinc and tin are better than steel, to steel plated to help improve the reflective properties of the surface. After a galvanized sheet steel can rust treatment, but incision may still rust.
