Nettle leaves and twigs are rare feed ingredients. In foreign countries, especially Russia, ramie is widely used as poultry feed. Feeding poultry with ramie not only improves the rate of production of the mother bird, but also prevents certain diseases of the young bird. It was determined that the dry matter contained in the castor leaves and twigs per kilogram contained 140 mg to 300 mg of carotene, 1000 mg to 2000 mg of vitamin C, 25 mg of vitamin K, and 320 mg of vitamin B. At the same time, its mineral content far exceeds the stems and leaves of other crops and wild plants. The content of iron, manganese, copper and zinc is also 3 to 5 times more than that of high-quality forage grass. In addition, ramie also contains tannins, organic acids and other biologically active substances. It can be fed directly to poultry with young leaves or seeds of castor, or it can be made into dry powder or vitamin slurry. It can be fed from 1-day-old young birds. At the beginning, a slurry is used, and later the young leaves are mixed in Used in powders. The P10 two-color display module all uses the JX5020 driver chip from Taiwan Macroaccumulation. The LEDs of each branch are correspondingly driven by an IC pin. One IC pin drives one LED. We use static cross-current The driving method ensures that the current of each IC can be guaranteed, and the normal guarantee will not cause the entire module to heat up due to the different scanning methods, which will cause damage to the IC, and the brightness of the LED will also be similar to the static cross current. The static cross-current drive ensures the stability of the entire screen.

When all the LED display modules are tested, paste QC, pass, and then perform the first semi-finished product test aging. The longer the aging time, the better, let him exceed 24 hours as much as possible, and then we will display the display module Put on the bottom shell, ready to start pouring.
The glue is filled with a fully automatic glue filling machine. After the ab component glue is combined, the filling is carried out according to the ratio of 10:1. It is better not to lower or increase the ratio. The ratio of 10:1 is just right. , It can be surface-dried in about two hours, and it will dry out in about 4-6 hours. Such glue will have a good guarantee for long-term use.
After the module is filled with glue, place the module on a horizontal plane, and test with a level meter, and then try to make each module as flat as possible, complete the 4 corners of the horizontal position on the same level, the choice of AB glue It is also very important. The AB glue choice must use more than 40 yuan per kilogram of glue. Its adhesion and durability will be very good. It cannot be filled with shoddy glue. It will crack after a long time. The screen will leak. Then put all the display modules in their masks and arrange them to start packaging.
