It is expected to achieve the goals of comprehensive utilization of potassium feldspar, reducing costs and increasing economic efficiency, because of its simple route, short process, easy materials.

Influence of Acoustical Absorbing Material on the Obstacle Detection Angle of an Ultrasonic Sensor Z.
This paper is focused on studying the influence of acoustical absorbing material on the obstacle detection angle of an ultrasonic sensor.
The detect point is independent of target size, material, or degree of reflectivity [4].

STUDY ON PROCESS AND MECHANISM FOR PREPARATION OF MAGNESIUM HYDROXIDE WHISKERS Jiang Yuzhi 1,a, Han Yuexin 2 ,Yin Wanzhong 2 ,Li Yanbo1 1.Materials Science & Engineering College, Shenyang Ligong University, Shenyang 110168, China; 2.
Taking alkaline magnesium sulfate whiskers and sodium hydroxide as raw materials, the proper process parameters were experimentally investigated for magnesium hydroxide whiskers preparation by hydro-thermal synthesis.
Such a high volume make the mechanical properties of composite materials declined or even not be used.
Fibrous magnesium hydroxide was prepared by physical separation with natural fibrous brucite as raw materials by Tang Kwok-early[4] and others.
In this paper, hydrothermal method is adopted to explore the technical conditions for preparation of magnesium hydroxide whiskers with alkaline magnesium sulfate whiskers and sodium hydroxide as raw materials.

The purpose of disassembly is to improve the value of materials recovered by manual or partly automated processes, removing hazardous substances or valuable parts from the whole parts.
Bulk recycling is designed to recover ferrous metals, non-ferrous metals, glass, plastics and composite materials.
Material recovery is typically affected by smelting and refining, and various smelting methods can be utilized to separate low value materials such as copper, aluminum and lead and high value precious metals such as gold and silver.
In ZIYA, remanufacturing products are limited to low value materials or components such as copper ingot and wire whose life could be shortened severely.
In our model, by integrating the forward logistics and reverse logistics, we can provide the raw materials and components recycled in ZIYA to the supplier or manufacturers in TEDA who can combine newer products with remanufacturing raw materials and components (i.e. a combination of newer and older parts) so as to manufacture higher value products compared to simply reassembling used parts together.
