　　4, the plate is scratched during the transfer process:

　　a, the handling personnel lift the amount of the board at one time is too much, the weight is too large, the board is not lifted during handling, but dragged along the trend, resulting in friction between the board Angle and the board surface and scratch the board surface;

　　b, when the board is put down, it is not put neatly, and it is forced to push the board in order to re-arrange it, causing friction between the board and the board to scratch the surface of the board.
