The overall economic performance of PP geogrid in china is good. When it is under the pressure of these foreign enterprises, no matter which part of the net is stressed, it will immediately transfer to the surrounding mesh, forming a technical innovation advantage of common development and bearing capacity, reasonable structural design and strong bearing capacity. The polymer mesh with square or rectangular shape formed by PP geogrid in china stretching can be divided into unidirectional tension and biaxial tension according to the different tensile directions when they are manufactured. It is to punch holes on the extruded polymer sheet (the raw materials are mostly polypropylene or high-density polyethylene), and then conduct directional stretching under heating conditions. Using polypropylene plastic (PP) and special additives, the flame retardant and antistatic plastic belt for underground coal mine has been successfully developed by using plastic directional drawing, flame retardant and antistatic technology. Through the inspection of national quality inspection department, the mining PP geogrid in china fully meets the requirements and obtains the production license. Glass fiber geogrid is a new type of excellent geotechnical base material for strengthening road surface and subgrade. The product is made of alkali free glass fiber filament as the main raw material, woven by unique warp knitting weaving technology and coated with special rubber. The characteristics are: smaller than the metal through the mesh, that is to effectively solve the problem of large building area, safety, good roof control effect, and conducive to strengthening the management of coal quality. Compared with bamboo harrow and metal mesh, the double resistance net of coal mine net has small volume and light weight. A roll of 8 square meters of plastic mesh is only about 4kg, while the same area of metal mesh weighs 25.5kg, which is convenient to lay and has low labor relationship strength. The plastic mesh is acid-base resistant and corrosion-resistant, and its working performance remains basically unchanged after one year's buried pressure

The overall performance of PP geogrid in china is good, when the external pressure, no matter which part of the net force, will immediately transfer to the surrounding steel wire, forming a common bearing technology advantages, reasonable structure and strong bearing capacity.

Through its characteristics: smaller than the metal mesh, that is, effectively blocking the area, good safety, and beneficial effect, roof control and management of coal, network and anti net double bamboo harrow, metal: plastic hoop volume is small, light weight. 8 square meters of plastic mesh only about 4 kg rollers; halo 25.5 kg with metal area is easy to lay and less labor-intensive. Plastic mesh is acid resistant, corrosion-resistant, and buried basically constant year underground performance, while metal mesh, due to severe corrosion, significantly reduces the strength.

Through the network laying of PP geogrid in china, the setting of the surrounding rock of port road is improved, and the phenomenon of roadway spalling and roof falling has been avoided. The safety technical conditions of roadway are improved, the occurrence of traffic accidents is reduced, the resistance of ventilation system leading to roadway is reduced, and resources and energy sources are saved. The plastic mesh is light, acid and alkali resistant, low price and easy to lay.

PP geogrid in china is a polyethylene, elongated, reinforced fiber-reinforced structure that is then welded to a new environmentally-friendly green building material with the character "character" that can be divided into a single, bi-directional bar welded into polypropylene geogrid. The product has high strength, small deformation, corrosion resistance, long life, convenient construction, low cost, flat laying and charging positioning, especially to meet the requirements of all kinds of permanent projects with more than 100 years.
