Description

Anping Jiasheng Metal Products Co.,Ltd main produce  geogrid road construction , we also named  geogrid , supply free geogrid sample, it can do fencing , it very nice

 1. Characters:

   geogrid road construction  for coal mine is mainly consisted of Polypropylene, through the special processing of anti-static and fire resistance, its characters as following:

 A.    Not easy to produce static when friction. Under coal mine, the resistance mean value of girds is 1×**9Ω

 B.    Good ability of fire resistance. In the environment of **0°C, only melting, no fire, it will extinguish as soon as the grids left flame if it fire.

 C.    Convenient to wash coal. The density of this grids between 0.*9 and 0.*1, below the density of water, the broken rids will float on the water during washing coal, easy to be wash out.

 D.    Good performance of anti-corrosion.

 E.    Convenient to construction and transport. It is not easy to hurt wokers because this kind of grids is sofe relative, convenient to pack and cut out, easy to transport under mine and construction.

 F.    High bearing strength in longitudinal and horizontal. After pressing and tensiling, grids’ molecule struction array newly, the materials’ elongation strength is greater 2—3 time than before. The ribs are vertical each other after double side elongated, this constrution can disperse press from grids surface to around ribs, thereby increased the whole grids’ bearing strength consumedly. When ourtside force act on one rib, the force will disperse to other ribs at the same time, reduce the concentrated force on one rib, not easy to rupture. And second, this grids is formed by double side tensile, not braided, so the creep rate is samll, and holes’ dimension is average, can avoid to drop cracked coal, protect works and tramcars’ safety. 

 2. Products Purpose

 This products mainly used in coal mine as ceiling and shield, also can be used to protect laneway when mining coal. It must double layers or more when used as ceiling.

 

 Introduction
• Biaxial Geogrid is manufactured from Polypropylene. It is produced through the process of extruding,
punching, heating, longitudinal stretching and transverse stretching.
