Market Share Increase of cell phone jammer

The company tries best to develop the advance  cell phone jammer  to provide the advanced technology, excellent product, and perfect technical support and service. Measuring the thickness of primer and topcoat meet the drawing requirements. Mobile phone parts for painting, the color of the substrate required paint color should be close. Test Methods: 1cm X 1cm area of 4 0 of copper velvet, plus 150g vertical force, the friction surface of the lens 200 (100 cycles). After the test does not scratch the surface of the lens inspection when qualified. Test method : The 1cmX1cm area 4 0 copper velvet, plus 100g vertical force, the friction surface of the lens 150 (75 cycles), check the test is completed when the lens surface scratches qualified. Test Methods: 1cmX1cm area 4 0 copper velvet, plus 100g vertical force, the friction surface of the lens 100 times (50 cycles), check the test is completed when the lens surface scratches qualified. with 3H pencil (Mitsubishi), cut the cartridge into cylindrical and polished on 400 mesh sandpaper after 1Kg force applied to 45-degree angle, push the pencil on the sliding surface of the product forward 5mm in length (5 total plans) and then a pencil eraser to wipe clean marks to check whether the scratches on the surface, below are a qualified (3H). The cell phone can recover use after leave the blocking range of cell phone jammer .
With the impact test machine, the ≤ ф12mm stainless steel ball, the height of free fall from 0.8m the lens surface after the (first shell fixed on the lens), a lens of the impact of five times, allowing the lens on the entry pits, but not cracks on the lens. GB corresponding reference standard, the neutral salt spray test for the lens, in 35 ℃ ± 2 ℃ in an enclosed environment, moderate> 85%, PH value 6.5-7.2 range, with 5 % ± 1% of Nacl solution after continuous 48h salt spray, requiring no moldy produce mirror Note 1: "This test is mainly aimed prone to mold the lens, such as a deposition process of the lens. Note 2: You can use room temperature with 5% ± 1% of the way instead of Nacl solution soak salt spray test. DOME with elastic stretch test measured the size of line drawings. endurance test machine with buttons, to exert a certain force (according to design requirements), press the speed of 40-60 beats / minute, press the button (with Dome) 10 million times, the test button after checking the appearance of non-cracking damage and functioning: Dome of the function is normal to pass. with a dedicated Norman RCA abrasion tester (Model :7-IBB-647) and a dedicated tape (11/16 inch wide 6 or 8 inch diameter), 175g load applied, the sample surface friction in the tape drive 200 cycles. The production process of  cell phone jammer  strictly conforms to ISO9001:2000 Quality System Standard.
Results found: PC membrane keys: keys not being worn surface of the film when qualified: PC transparent button: key surfaces to allow a slight wear and fuzzy, but the button at the bottom of the font is still clearly recognized when qualified: PK button: paint not through the end of screen printing is still clearly recognized when qualified: silicone keypad: Press the surface of the font is still clearly recognized when qualified. with a sharp blade (blade angle of 15 o ~ 30 o) in the test sample surface, designated 10 × 10 个 1mm × 1mm small grids, each crossed several coating of the substrate should be deep: the test area with brush brush to clean debris: The adhesion of the tape 350 ~ 400g/cm 2 (3M600 No. tape or equivalent) firmly stuck tested a small grid and use the eraser wipe hard tape to tape and measured the area to increase the contact area and intensity; hand to seize the tape at one end, in the vertical direction (90 o) quickly ripped off tape, the same location 2 times the same test. Results found: requirements for adhesion of 5B qualified. 5B-crossed with smooth edges, the edge of the dash and no peeling paint at the intersection. Don’t point the antenna of  cell phone jammer  to the cell phone base station or otherwise the using effect will be influenced.
4B-crossed the intersection in a small piece of paint off, and off a total area of less than 5%; 3B-in and crossed the intersection at the edge of a small piece of paint off, and off 5% of the total area of 15 percent. 2B-in and crossed the intersection at the edge of the paint off successful films, and the loss of the total area of 15% to 35%. 1B-in and crossed the intersection at the edge of the paint off successful films, and the total area of 35% off ~ 65%; 0B-in and crossed the intersection at the edge of the paint off successful films, and The total area of more than 65% off. Note: When the test area is small, not required by law to draw 10 × 10 small squares, depending on the test area to determine the size of a large number of small, requires no coating off. With a dedicated Norman RCA abrasion tester (Model :7-IBB-647) and a dedicated tape (11/16inchwide6 or 8inch diameter), applied \ 75g load, the friction surface of the sample tape drive 200 cycles. Results found: After the test through the end of the coating is not qualified. Cotton cloth soaked with ethanol (concentration ≥ 99.5%), weight 500g wrapped in a dedicated head (wrapped in cotton after the first test area of about 1cm 2). mobile phone jammer  has gain the support from the China Mobile, China Unicom and radio management committee and so on.
With a 2H pencil (Mitsubishi), whittled the cylindrical cartridge 400 mesh sandpaper and polished on after installed in a dedicated pencil hardness tester (load applied to the tip of 1Kg, pencil and the horizontal angle to 45 o), push slide forward about 5mm long pencil, draw a total of 5, then a pencil eraser marks Bible wipe clean. Soaked in sweat after the non-woven surface attached to the product and sealed with a plastic bag placed Fortunately, after 24h at room temperature environment, the product of sweat wipe clean surface, the appearance of the coating inspection, and test the coating adhesion and wear resistance. Results found: without exception the product surface coating, adhesion and wear resistance tested. Note: The ingredients of sweat ammonia 1.07%, 0.48% sodium chloride, the rest is water. Requirements: The switching time between the temperature is less than 1min, 12 cycles were done (48h). After the test checks the surface of the plating layer of the product without blistering, peeling, coating loss and other negative phenomena, and test the coating adhesion and wear resistance qualified.  cell phone jammer  can effectively block various cell phone signals and there will be no missed point.
