In recent years, the news has often reported about people swallowing people at the wellhead, especially when there is heavy rain. Now many provinces and cities have installed anti-fall nets for local wellheads, so that even if heavy rain washes away the manhole cover, there will be no tragic incidents of passers-by falling into the well.

What is the anti-fall net? Can a small net really protect our personal safety?

Then, let me show you this amazing little Internet cafe for popular science!

The manhole cover anti-fall net is made of polypropylene high-strength wire or polyethylene mesh wire. The middle is a galvanized coated iron ring and the net is connected. The protective net is surrounded by polyethylene rope for hanging on the inner wall of the wellhead. The protective net can support Function to prevent casualties caused by falling. It is made of high-quality nylon rope, the breaking force of a single rope can reach 650 kg, the mesh is small and uniform, and the knot will not move back and forth, even if the child falls, it can ensure safety.

In addition to being used in anti-falling nets, what other uses are polypropylene high-strength yarns?

Polypropylene high-strength yarn has the advantages of high strength, anti-aging, abrasion resistance, acid and alkali resistance, and its light weight. It is widely used in woven geotextiles, packaging bags, and fire hoses and safety belts. In other fields, it can completely replace polyester new chemical fiber materials.

In addition, polypropylene high-strength yarns are widely used in metallurgy, chemical, light industry, environmental protection and food industries, and have good non-absorbent and stable performance.
