Magic Curtains Can Prevent Hurricanes.

In December, the JHRG Storm-A-Rest new era of science and Technology (the simplified Chinese version of Popular Science, the famous American science magazine) published the annual "100 best scientific and technological achievements", covering 11 fields, such as entertainment communications, automobiles, computers, photography, safety, health care, green, aerospace, household, engineering, sports and leisure.

Below is the best technological achievement of household technology. Now, we must simply pull down the curtain to resist the 4 class hurricane.

JHRG's window curtain made of thousands of grams of 0.6 millimeter thick material is stronger than plywood, which is Storm-A-Rest.

In the experiment, they used compressed air guns at a speed of 55 km / h to shoot an area of 5 * 10 cm on the Storm-A-Rest screen, which was equivalent to 4 grade hurricanes. The curtain was intact, but the plywood in the experimental group was broken.

Even better, it allows 80% of sunlight to pass, so even if the electricity is stopped, it will not be dark in the room.

Storm-A-Rest's strong resilience comes from the Honeywell Spectra fiber - some bullet proof vests that also use this material and meet the harsh building standards of the state of Florida.

In order to create a windproof, waterproof coating that can be attached to Spectra smooth polyethylene fibers, JHRG spent two and a half years experimentation with existing coatings in various temperature and environmental conditions.

In addition, engineers need to find suitable weaving methods and density so that the curtains will not rebound too much.

Finally, they found that a little loosening of the weave is the most effective way to break down the impact force.

"We were hit by a series of hurricanes in 2004, and the development of windbreak products became hot."

Michael, a building contractor in Florida, said, "we have used other products, but only this one can really withstand hurricane attacks."
