EVA plus adhesive to improve bond strength (such as rosin), glue viscosity and solidification speed regulator (such as paraffin) and a small amount of antioxidants (to slow down the aging rate of hot melt adhesive), after high temperature melting, cooling solidified into a block of solid adhesive. EVA is not heat resistant, the softening point is low, and it should be heated when used to melt the solid EVA resin. whenWhen heated to 80 ~ 100℃, the colloid is slow, and the flow is gradually accelerated with the increase of temperature.

Printing speed: laser printerOften has faster printing speed, especially suitable for high-volume printing tasks. Inkjet printers are relatively slow, especially when processing large amounts of text or images. Printing effect: When the laser printer prints black and white documents, the handwriting is clear, the edge is sharp, and the imaging quality is high.
A), advantages: laser printer supplies are toner cartridge, printing speed is relatively fast, the daily printing amount (monthly load) is large, the handwriting is clear, the color depth can generally be adjusted. Because the toner cartridge is toner inside, as long as the toner cartridge is not light and damp, it can be stored for a long time. The machine is more durable, and the relative service life is longer. (2) DisadvantagesCompared with inkjet printers, the price of laser printers is higher.
In terms of printing speed, laser printers have obvious advantages. Laser printers can achieve a full page of output at a time, while inkjet printers usually print one line at a time, so the speed is slower. For office or home users who need to print a lot, laser printers can complete printing tasks more efficiently. As for the printing effect, laser printers and inkjet printers have their own advantages.
In consumables: laser printers use toner printing, printing speed response is very fast, the most important point is to printHandwriting is much clearer than inkjet printers. Because of the use of toner, even if idle for a long time to use again there is no problem.
In terms of consumables, the first difference in consumables, the toner cartridge and toner used in laser printers, and inkjet printers generally use ink cartridges, and now some inkjet printers use ink bin design, which can be directly filled with ink. In terms of use cost, the use cost of ink cartridge inkjet printers is the highest, followed by laser printers, and ink bin inkjet printers are more cost saving.
1, Nokia 920 uses wireless charging as follows long distance (about 4 meters) charging Apple is under development.
2, Lumia 920 Qi wireless charging is how to charge? It is understood that Qi wireless charging technology is achieved by two new devices, the first is the charger, it is connected with power, and then there will be a "tray" and the charger for transfer, as long as the mobile phone and "tray" (the mouse shape of the base in the official figure) distance within the specified range, then the mobile phone will automatically wirelessCharge up.
3. Nokia 920 supports unlimited charging. Need to buy a wireless charging base, when you need to charge, put the phone back shell attached to the charging base to charge. During the wireless charging process, the phone will heat up, pay attention to safety.
4, Nokia 920 can be wireless charging, using the QI wireless charging standard. Nokia Lumia 920 built-in wireless charging, just put the phone on the wireless charger tray, you can start charging the phone.
5, wireless charging is generated by coil induction, so the phone needs to be placed on the charging padp >
