Introduction Magnesium alloys are the lightest structural materials with high strength-to-weight ratio, good electrical/heat conductivity and damping properties.
Furthermore, many researches were done recently in order to use it as bio implant materials [1, 2].

It is characterized by large transport capacity, low power consumption, simple structure, and strong adaptability to raw materials.
But once the belt have problem of running deviation, slip, unglued, longitudinal tear and so on, light was materials scattered or cannot transfer material, or belt will be cut, torn or even fire.
Belt Spreading Materials and the Handling.
In general, spreading material failure of belt conveyors occurred, including three cases: spread material in Reprinted point, spread materials when belt left vacant in Concave section, spread materials when deviation.

Microfiber synthetic leather is a high mimetic material of natural leather.
Compared with other synthetic leather, it is a material which is most like to natural leather and its performance is the best.
For that reason, many researchers try to introduce some materials containing many active groups to synthetic leather in order to improve the hygienic and dyeing properties[3-6].
(1)Weighing: The weight of microfiber synthetic leather base was weighed accurately, as it was as the basis of the quantity of chemical materials used in following processes
