Artificial Turf

Artificial turf divided into fields for soccer fields for rugby, golf tennis and others. There is grass, which are used for multiple sports. Production and development of coatings artificial grass are concentrated in companies that manufacture carpeting, as the technology of weaving coatings are very similar. Thus, first came up with the production of coatings, resembling a carpet. Artificial turf – is roll coating.

It is cold-resistant, light resistance, water tight and does not form stagnant zones. It’s believed that Expa sees a great future in this idea. When producing such a coating technology is used tufting. Simulate blades of grass bulk fiber weave into high ground, covered with latex. The material of fibers – polypropylene, polyethylene, or a combination, sometimes – fiber nylon. Polyethylene is a soft fiber, and more slippery. If you fall on coating of polyethylene will not burn and abrasions, which could get a fall in the polypropylene coating. It is also important that the polypropylene can withstand temperature regimes Operating from -10 to +40 C, and polyethylene from -50 to +50 C, for different climatic zones of Russia and the cis is an important factor.

Typically, coating of polypropylene is cheaper than the coating of polyethylene. Mounting method divide these coatings Plumbing Infrastructure (with a layer of quartz sand or rubber granules) and nezasypnye. Charging on the fields, you can adjust the height of "stems" for various sports. Rubber backing helps prevent "Burn" athlete falls to the ground. Different sports require different types and artificial grass, which differ from each other in the source material, height, density and structure of the pile, used supplemental materials.

The Material

They have such advantages, such as longevity, good self-cleaning effect, high bandwidth. Drainage trays are equipped with various types of gratings: steel, iron, copper. Lattice can be either slotted or honeycomb. However, the most popular way – is to install drainage pipes at the site. The appearance of plastic, polyethylene and polyvinyl chloride (PVC) plastic pipe (such as UPONOR), as well as water intake pipes with a layer of fibrous-porous polypropylene significantly simplified the drainage works. These tubes can be operated with 50 + years. In addition, there are complete "linear drainage systems (eg, hunter ), equipped with special filters that prevent silt and system eliminates the need for cleaning of drainage for a long time.

Important questions about the pipes and pumps to pipe served long and effectively, they must take care of. Drainage pipes must wrap the filter material (geotextile) to protect against ingress of clay particles (silt). For example, high filtering ability is different geotextiles typar. It is a non-woven material technology with "span-bond" of polypropylene fibers, which ensures its high physical and mechanical properties (eg isotropy), as well as resistance to various chemical compounds (Alkalis, acids). The material does not rot, fungus and mold exposure, root penetration. The structure of the geotextile provides good strength and filtering properties. In addition to use of geotextiles volume drain filters. They are made from textile waste, straw, grass, fibrous peat, coir and other materials. Bulk filters not only protect the plastic drains from silt, but also improve and enhance the inflow of water.
