1, with vinegar soaked cloth, cover the entire double-sided tape traces, until the back glue is all wet vinegar cloth after soaking, use a ruler to gently remove the back glue. Can beTo use the usual nail polish to remove nail polish water, the nail water on the glue, wait for a few minutes, the glue will fall off, you can now a small place to experiment.
2, how to remove the adhesive on the back of the phone? The following are several effective methods: wind oil essence method: The wind oil essence is applied to the area of adhesive residue, let it sit for a few minutes to take effect, and then gently wipe it clean with a damp cloth. Toothpaste method: Apply a small amount of toothpaste on the adhesive part, if the glue stain is dry, you can dilute it with water. Gently massage the spots to soften them.
3. Try using an eraser. It may feel dirtier and dirtier at firstBut after a period of time, the adhesive will gradually loosen, and this method is more laborious and requires patience. Soaking the phone in water, adding a small amount of dish soap, and then scrubbing it with an old toothbrush can effectively remove the adhesive. With a cloth dipped in alcohol or erguotou, directly wipe the adhesive part, can also achieve the effect of removal.
4, if the phone case is accidentally contaminated with 502 glue, you can try to use a warm wet cloth on the adhesive. After waiting for about 10 minutes, the cured glue usually becomes soft and can be removed by a gentle wipe. If the glue is not fully cured, you can directly drop a drop of 502 glue on the glue, whichThe sample can make the cured glue soft again, and then wipe with a damp cloth to remove. Adhesive 502 glue can be treated with insulating oil.
5, to remove the adhesive on the phone case, you can try to use nail polish remover. First, set the hair dryer to hot air mode and blow hot air at the adhesive area until the adhesive softens. Next, apply nail polish remover to the adhesive and wait about 5 minutes. Finally, wipe gently with a rag until the adhesive is removed. If the adhesive is difficult to remove, you can try the following method: Drop some 502 glue on the adhesive, let it melt, and then quickly rinse with water.
2, the third thing you can see is the camera, some without a front is either too early or too low-end. Some manufacturers label their pixels near the rear camera, but the higher the pixel, the better.
3, for these old mobile phones that can still be used, they can be sold to shops specializing in refurbishing mobile phones. Some smart phones can be sold for more than 100 yuan, while some feature phones can also be sold for about 50 yuan. In this way, it is also a lucrative link. Disassemble and sell electricityFor those phones that cannot be used and are badly damaged, their electronic components can be dismantled and sold. Normally, a used mobile phone can be sold for about 30 yuan after being disassembled.
4, about 0.03 grams of gold, depending on the material used. According to the survey, the average smartphone uses 0.03 grams of gold, which is mainly used in circuit boards and other internal accessories. By recycling old computers and smartphones, Apple recovered more than 61 million pounds of steel, aluminum, glass and other materials, as well as 2,204 pounds of gold.
Special adhesive for polytetrafluoroethylene. Polytetrafluoroethylene has excellent comprehensive properties, high temperature resistance, corrosion resistance, non-stick, self-lubrication, excellent dielectric properties, very low friction coefficient. Used as engineering plastics, can be made into polytetrafluoroethylene pipe, rod, belt, plate, film, etc., generally used in high performance requirements of corrosion resistant pipes, containers, pumps, valves and radar, high frequency communication equipment, radio equipment.
Production method of polytetrafluoroethylene fiberThere are four main methods: emulsion spinning, paste extrusion spinning, film splitting spinning and melt spinning. Emulsion spinning method is the main method used in industry, through the polytetrafluoroethylene emulsion mixed with viscose silk or polyvinyl alcohol and other fibrillating carriers to make spinning liquid, spinning and removing the carrier to form a continuous fiber.
M polytetrafluoroethylene tape bonding strength is very strong, for many surfaces can be quickly adhered to, showing excellent bonding strength. Use 3M Teflon tape black and yellow strip safety tape to mark and identify safe areas, this tape has unique tensile properties over irregular, curved linesAnd the convex surface has good shape, while maintaining the stretched state after use, will not be lifted.
Plastic products can be broken with 502 glue to stick. 502 Glue is used for porous and absorbent materials, followed by steel, non-ferrous metals, rubber, leather, plastics, ceramics, wood, non-metallic ceramics, glass and flexible materials such as rubber products, shoes, soft, hard plastics and other adhesive or mutual. However, for polyethylene, polypropylene, polytetrafluoroethylene and other difficult materials, the surface needs to be special treatment, can be bonded.
1, in the electroplating process, the electroplated potion enters the line inside the charging coil along the cavity, and ultimately affects the molding quality of the wireless charging circuit board.
2, when using the compass, the magnetic phone case will have an impact, and it has no impact on other functions or internal data. At present, most mobile phone devices in the market, there will be a number of very small but important role of magnets. The latest generation of Apple Watches, for example, uses a magnetic inductive wireless charging system. When using a compass, because the mobile phone needs a magnetic field to determine the direction. <3, the practicability and safety of Nank charging treasure is in the industry has a reputation, the use of polymer lithium battery, and is through the military level of safety certification, joined the intelligent foreign body detection and 9 safety protection, in the charging safety to do strict protection measures. It can be charged at a short distance of 5 mm, and can be charged wirelessly even with a phone case.
4, recommended reasons: This charging bank is recommended to use millet support wireless charging mobile phones and iPhone support wireless charging mobile phones to use, at present, whether it is wireless charging or wired for iPhone handsThe machines are very advantageous.
5, the right crown adopts stainless steel plating, supports rotation, long press, click mode, used for power switch, enter the menu/return to the main dial, switch dial/sliding page control. Pressure relief holes and speaker sound holes are provided on the left side of the dial. The dismantling process of the smartwatch includes removing the watch band, removing the screen and bottom cover of the watch face, and displaying the internal structure configuration.
