Use safety net features :
Features : high strength, lightweight mesh , heat ventilation, light the fire , dust and noise .
Uses: used in various construction sites, especially in high-rise buildings , the construction can be closed . Can effectively prevent personal injury falling , objects to prevent fires caused by welding sparks , dust and reduce noise pollution , to civilization construction , environmental protection, urban beautification effect

Safety Net requirements :
Check the contents of ( 1 ) the network include : construction waste shall remain within the network , the net can not be stacked items, net itself is not severe deformation and wear , as well as whether it will be subject of chemicals and acids, alkalis smog pollution and welding sparks burning , etc. .
( 2) The support frame may not appear serious deformation and wear , it may not have loose joints phenomenon . The connection point between the network and the network between the network and the support frame and also does not allow loose. All tied rope can not pull it severely worn or deformed.
( 3 ) falling objects within the network to be always clean . Mesh to keep clean . Also avoid the large number of welding or other spark off the network, and to avoid heat or steam environment. When a mesh or net rope contaminated chemicals embedded coarse sand or other foreign matter may cause wear and tear , shall be cleaned , washed it dry naturally .
( 4 ) Safety nets can not be used during transportation or fishing with a spiked iron tools , rope nets to prevent damage . Mesh to be stored in a warehouse or a special place , and classification , in batches stored on the shelf, do not allow arbitrary huddle . Requires warehouse ventilation, shading, heat, moisture, prevent erosion of chemicals and other conditions. During storage , also requires regular inspection body for the network , identify problems , dealt with immediately to ensure safety .

Quality checks the safety net
( 1 ) safety net involving state property and personal safety of the special labor protection products , the quality of their products must be inspected by the state designated qualified supervision and inspection department and obtain production licenses only after production . Each batch safety net factory inspection report must have supervision and inspection departments. Each safety net should be at different positions , attach national supervision department inspection certificates and corporate self-test certificate. At the same time there should be signs, there should be a permanent mark on the signs, signs should include: name of manufacturer , date of manufacture , batch number, material , size , weight and production license number .
( 2 ) safety net into flat screen (P), set up the network (L), dense mesh safety net (ML). Safety nets mainly by side ropes , tethers , tendons rope, net rope components. Dense mesh safety net consists of mesh , buckles , side rope and attach the tether . Mechanical properties of the physical safety nets , safety nets are the main indicators of the quality of the merits of the judgment . Its contents include: side ropes , tethers , net rope , rope breaking strength bars . Dense mesh safety net are: breaking strength , elongation at break , tensile strength seams , tear strength, penetration resistance , breaking strength retention after aging , opening the eyes buckle strong tail flame retardant properties. Flat screen and vertical networks should have impact resistance. Legislative Network can not replace flat screen , flat screen should be used to distinguish between the height or vertical networks based on construction needs and load. Flat screen larger than the vertical network load strength requirements , the materials are more heavier than vertical networks . Under normal circumstances, the flat screen is larger than 5.5kg, Li net more than 2.5kg.
( 3 ) safety net is mainly used outdoor workplaces . So , you must have weather resistance. Weather resistant materials are nylon, polyvinyl alcohol and polyester . With a mesh material used should be the same , its wet and dry strength ratio should be greater than 75 % per net total weight does not exceed 15kg. Retardant safety net continued burning , smoldering time shall not exceed 4s.
( 4 ) flat screen width of not less than 3m, establish networks and dense mesh safety net width of not less than 1.2m. Tether length not less than 0.8m. Safety net tether and tether spacing should not exceed 0.75m. Dense mesh safety net tether and tether spacing should not exceed 0.45m, the distance between the rope safety net tendons shall not small, the general provisions in 0.3m or more. Safety nets can be divided into hand knitting and machine knitting . Machine knitting can be divided into a knot knotted and knotless knotted . Generally, knotless nets have higher knot strength webs knot strength . Network node and section head must be firmly fixed , not move , and to avoid increasing the mesh side length uneven. Such a situation would lead to stress is not concentrated until the net rope breaks.

Precautions Safety Net
1 , when used, should avoid the following phenomena:
⑴ casually dismantling the safety net component ;
⑵ people jumped or put items into the safety net ;
⑶ lot of welding or other Mars Mars falls within the safety net ;
⑷ within or below the safety net accumulation of goods ;
There are serious safety nets around ⑸ corrosive fumes.
2 , the use of the safety net should be regular or irregular inspections , and promptly clean up contaminated debris falling networks , when subjected to a large impact should be replaced.
