Successfully fabricated coating to prevent splashing of urine

Why are we going to pee when we pee? The flow of water from the body will break and form small droplets and when these water droplets hit a surface such as the urinal, they will splash back and your pants are beautiful. But . unsightly in the right place.

Successfully fabricated coating to prevent splashing of urine

Because of this, a group of scientists and Splash Lab at the University of Utah, USA have devised a solution with a coating of urinals like Syntrichia caninervis - a kind of Moist moss has many vertical spines.

This coating design was demonstrated by the team at the 68th Annual Fluid Dynamics Physics Conference in Boston, Texas. They said : "With the primary goal of addressing the natural splashing characteristics of urine , we sought an ideal " black hole " for urine by performing a series of tissue tests. We propose an improved urinal surface coating design based on test data in the hope of minimizing the risk of confusing you with khaki pants. "

Like Syntrichia caninervis moss , this coating has a surface consisting of a series of small, precisely arranged spikes. When peeing, you just "aim and discharge" into the coating placed in the urinal, the thorns will retain all liquids without them bouncing back.

Although the "noble goal" of this invention is to prevent urine from splashing , the development team believes that their research holds many other scientific potentials. 2 researchers Tadd Truscott and Randy Hurd said: "We believe that the scientific community will enjoy the interaction between splashing water droplets and vertical spikes in the surface of the coating."

Interestingly, this is not the first time Splash Lab has tried to solve the problem of splashing urine. In 2013, they used a 3D printing model of male urinals to shoot out water currents that simulated natural peeing behavior and used high-speed cameras to record patterns of water droplets shot back. in many different angles. From this experiment they concluded that to limit splashing urine, you should stand as close to the urinal as possible and adjust the angle of urine flow downward.

Therefore, while waiting for this type of urine splash coating to become more popular, you should follow Splash Lab's advice. This method also works well with a normal toilet, but Hurd says he does not encourage people to do it this way because it is not easy to aim for urine on the toilet, which often fires on the toilet. So he was happy that this method was only for "snipers in the army".
