The area along pointing direction of directional antenna of cell phone jammer

Make sure the entire production process, testing methods, to ensure product reliability. A plastic material selection of ways to understand the performance of plastic engineering plastics molding sometimes appeared very strange. The area along pointing direction of directional antenna of cell phone jammer  will be the area where the shielding signal will transmit farthest.
The answer to a molding problem may be completely different from another molding. This may be because of these examples involve two essentially incompatible with the plastic resin. 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. Measurement and control of the injection in the injection molding is very important. Although these measurements are relatively simple, but the majority of injection molding machines are not enough temperature sampling point or line. In most injection molding machine, the temperature by the thermocouple sensor. A thermocouple is basically composed of two different wire tail phase. If one end than the other end of the heat, will produce a tiny telecommunications; more heated, the stronger the signal. Use many cell phones of various frequency channels to test shielding effect of cell phone jammer  at site.
Temperature control thermocouple is also widely used as sensors for temperature control system. In the control apparatus, set the desired temperature, the sensor and the set point temperature is compared. In this simple system, when the temperature reaches the set point, it will turn off power after the temperature dropped again to open. This system, known as the opening and closing control, because it is either on or off. ? molten plastic temperature of the melt temperature is very important, the use of radio material cylinder temperature is only guidance. Melt temperature can shoot the mouth at the measure or the use of air injection method to measure the The injection cylinder temperature setting depends on the melt temperature, screw speed, back pressure, shoot feeding quantity and injection cycle. According to this, the position of cell phone jammer  can be predicted when doing the honeycomb position arrangement in the large area.
If you are not processing a particular level of plastic experience, please start from the lowest setting. In order to facilitate control, shooting material cylinder sub-district, but not all are set to the same temperature. If the operation time is long or operating at high temperatures, set the temperature set to a lower value, which will prevent plastic premature melting and diversion. Before the start of injection, to ensure that the hydraulic oil, closed hopper, mold and shoot material cylinder in the correct temperature?

The DC-DC converter input voltage is used for cell phone jammer

In terms of the current situation applies to cell phones with small memory capacity, 3GPP video format is very easy to send MMS MMS, most of the support for video recording cell phone supports video playback in 3GPP format. In 1998, the founding of the United Nations International Organization for Standardization ISO and the International Electrotechnical Commission IEC MPEG encoding standard. Stands for Moving Pictures Experts Group Chinese translation of the Moving Picture Experts Group. They developed three versions of MPEG, respectively, MPEG1 the MPEG2 MPEG3 which MPEG3 our daily often have access to all of us are familiar with is the MP3. Subsequently the organization to develop the two new image compression standard is as MPEG4 MPEG7. One of working frequency of common cell phone jammer  in the market is 869~894MHz.
MPEG4 is a compression standard for ultra low bit-rate moving images and language. His advantage. MPEG4 compression ratio high, the low bit rate transmission of video. Small compared to MPEG1 the MPEG2 MPEG4 encoder optimized image files, a higher compression ratio, better clarity. Can reach up to 768 * 576 definition, this definition has been close to the DVD picture. We may in this regard is not too concerned about, then talk about the application. MPEG4 compression algorithm Divx video coding technology to the 120-minute movie can be compressed 600MB, you can also compress a DVD to two CD-ROM, so that we do not have to use the DVD device to enjoy DVD-quality images . For the application of mobile video, MPEG4 smaller bandwidth for video transmission. 1900~1990MHz is also contained in the working frequency of cell phone jammer .
The cell phone's hardware can not be compared with the computer, so MPEG4 on the cell phone does not like on a computer so powerful. Many camera cell phones can capture low-resolution MPEG4 video, the same, and now most of the cell phones support download and play MPEG4 video. RM famous Real Networks Inc. to develop audio and video compression specification. RM format all known as Real Media. It contains the file format of the audio stream real audio and video streaming file format real video file. He is a compression format developed by Real Networks Inc., a major for the online real-time transmission of video and audio information in the low rate. The DC-DC converter input voltage is used for cell phone jammer .

 Shield leakage coupling structure with the required suppression of the electromagnetic frequency is closely related to three types of shielding frequency range involved and control elements as shown in Table 5: Table 5 leak coupling structure and control elements of the type of magnetic shielding electricity shield shielded shielding frequency range of 10kHz ~ 500kHz 1MHz ~ 500MHz 500MHz ~ 40GHz shielding shell leakage coupling structure and the ground shield shell apertures and ground elements of a reasonable choice of shell material control selection shell material well-grounded and reasonable apertures suppress the actual leak grounded shield at the same time there are multiple leaks coupled structure (n a), based chassis seams, vents, siding and other shield leakage coupled structure separate shielding effectiveness (eg, consider only the seams) to SEi (i = 1,2, ..., n), then the shield shielding effectiveness of the total can be seen from the above equation, the shielding effectiveness of the shield is coupled by the structure of the various leakage greatest leakage coupling structure of the decision, that is shielded by the weakest link of the decision of. Therefore, we can guarantee the effect of MDPB-02 cell phone jammer.Therefore, shielding design, clear structure of the different bands of leakage coupling, coupling elements to determine the maximum leakage is the primary design principles. In the three types of shielding, magnetic shielding and electromagnetic shielding more difficult. In particular, electromagnetic shielding design the most critical hole seam leakage suppression, shielding design should focus on a primary factor to consider. Figure 4 Schematic diagram of a typical cabinet under the hole coupling theory, the decision apertures leakage has two main factors: hole seam line area and the maximum degree of size apertures. The blocking range of cell phone jammer is better a bit larger than the area of the field.Both Jietai, the most serious leaks; area of small and large size of the largest degree-line electromagnetic leakage is still large. Figure 4 shows a schematic of a typical rack, above the apertures can be divided into four categories: chassis (cabinet) type of sewing seams Although small in size, but the degree of its maximum line size is very large fracture length, due to maintenance, open constraints, resulting in electronic equipment such as sewing the largest category of difficult mask apertures, conductive pads, and other special shielding material can effectively suppress electromagnetic leakage.

Electrical shielding principle is to ensure good grounding conditions, the interference generated by the source of interference in the end made a good conductor shield. Therefore, a good grounding and a good conductor of choice is the electric shield as the shield can play two key factors. The principle of magnetic shielding for interference by the magnetic field shield provides a low reluctance magnetic path, and thus interfere with the magnetic field triage, chose steel, iron, permalloy high permeability of the material and design boxes, shells and other closed-shell magnetic shielding of the body as two key factors. The principle of electromagnetic shielding by the metal shield by absorption and reflection of electromagnetic waves radiated interference source to shield the far-field, that is, while shielding the electric field generated by the field source and the magnetic field component. Install and use the cell phone jammer combining with the practical condition of the field.
As the frequency increases as the wavelength becomes with the shield on the apertures of the size equivalent to a hole leading to shield electromagnetic shielding seam leakage as the most critical control elements.  Vent hole area and maximum class size of a large line of degree, air ventilation hole design is the key to the choice of components and assembly of structural design. Performance in meeting the conditions of ventilation should be used as the shielding screen-efficient ventilation components. Watch the hole and shows the type of hole-hole area and maximum wire size of a large degree, the light shielding design is the key to the choice of materials and assembly of structural design. Connector and chassis joints such seam line area and the maximum degree of size are not large, but at high frequencies lead to the chassis connector contact resistance increases rapidly, making the shielded cable common-mode conducted emissions become larger, often leads to the emergence of excessive emission of radiation equipment, this should be conductive rubber connector conductive pad.If you have not been authorized by manufacturers, please don’t install or uninstall the cell phone jammer privately. In summary, the apertures suppress design features summarized as: a reasonable choice shielding materials; rational design and installation of interconnect structure.

If a good conductor shield grounded, then it also has high-frequency magnetic field shielding and shielding effect. Frequency of 500kHz ~ 30MHz range, optional aluminum shielding materials, and when the frequency is greater than 30MHz, it can optionally aluminum, copper, copper silver and so on. Incorrect good conductor shield material on the right openings or cracks try not to cut off the current, affecting the magnetic shielding effect. Combining with the development trend of mobile mechanics of communication in the future, cell phone jammer company has built its own brand.Permeability changes with field strength magnetic flux density B = B / H saturation maximum permeability initial permeability of the magnetic field strength H magnetic field shielding the high magnetic permeability material: saturated low permeability materials: low-permeability screen effect is not enough material of high permeability materials, how to shield low-frequency magnetic field? Low-frequency magnetic field high-frequency high-conductive material conductive materials to absorb losses small reflection loss of small electromagnetic shielding material of high permeability magnetic shielding and electric field, magnetic field shielding different.The cell phone jammer company adopts advantages of other firms. Electromagnetic shielding to prevent electromagnetic shield is spread in space, a measure electromagnetic field in the electromagnetic field through a metal or a dampening effect on the barrier layer, it will be a certain degree of attenuation that produces shielding effect. The mechanism is electromagnetic energy when passing through the shield with the loss, this loss can be divided into two parts: the reflection loss and absorption loss. When the incident electromagnetic wave reflection loss is a different medium to the interface occurs when the reflection, so that electromagnetic energy across the interface decreased. As a result of reflection phenomenon known as the reflection loss of electromagnetic energy loss. Absorption loss in electromagnetic wave shielding material is spread, there will be some of the energy converted into heat, leading to electromagnetic energy, the loss of this part of the energy absorption loss as shielding material. Skin effect of electromagnetic wave attenuation conductive medium, with the frequency, magnetic permeability, conductivity increases. The cell phone jammer firm absorbs advices from customers.In a good conductor of electromagnetic waves exist only on the surface. Skin Deep: δ = (2 ωγ) 1 2 shielding electromagnetic shielding pre-masked field strength E1 E2 of the electromagnetic field strength attenuation function is to generate electromagnetic shielding, electromagnetic shielding effect of the size of the shielding effectiveness measurement: SE = 20 lg (E1 / E2) dB shielding attenuation of the relationship between performance and shielding effectiveness of 20 dB 40 dB 60 dB 80 dB 100 dB 120 dB the original field strength 111 111 masked field strength 0 0.1 0.01 0.001 .0001 0.00001 0.000001 attenuation 90% 99% 99.9% 99.999% 99.999% 99.99% shielding effectiveness of solid materials, the incident wave field strength B calculated absorption loss A R1 R2 from SE = R1 + R2 + A + B, R1, R2 represent two surface reflection loss, A is the shield of the absorption loss, B Loss on behalf of multiple reflections, A bigger, B is smaller.cell phone jammer company has built and developed a series of cell phone jammer. The key to the shielding design and electromagnetic waves can provide the majority of metal shielding effectiveness of more than 100dB. However, in practical engineering, to achieve more than 80dB shielding effectiveness is very difficult. Because the shield of shielding effectiveness depends not only on the material composition of the shield, but also on the shield structure.
Shield electromagnetic shielding to meet the two basic principles: 1. Conductive shield continuity: refers to the entire shield must be a complete, continuous conductor.
