Product Details

Product Description

Introduction

The plastic security network used underground in the coal mine is a kind of “double-resistant” plastic network developed independently by our company. The product is convenient to operate with the advantage of low cost and beautiful outlook. The main characteristic is that it is not easy to static friction and has good flame retardancy, anti-corrosion and it is convenient in the construction and transport to facilitate coal washing both vertically and horizontally to the carrying capacity.

Function

The product is mainly used at the time of protection for the exploitation of coal mine and also can be used as anchor of roadway support, anchor spray roadway and other material support. When used in the fake top, be sure to use double-deck joint above.

Feature

The product is based on polypropylene as the main raw materials, through flame-retardant, anti-static treatment, the bi-oriented approach taken by the formation of the overall structure of the grid network.

1. Attrition is not easy to cause static friction.

2. Good flame-retardant performance.

3. It can facilitate coal washing.

4. Strong anti-corrosion, anti-aging.

5. Facilitate the construction and transport, carry and construction.

6. Have strong carrying capacity in vertical and horizontal direction after extrusion and stretching process of the plastic, the molecular structure of materials is re-orientated.
