The expansions of six kinds of rollers made of plastic synthetic materials, immersed in the liquid (water and urine of dairy cow), were investigated through 400 hours.
Diameters of rollers increase with immersed time and water pressure, and increase a little more in the urine of dairy cow than water.
These are especially remarkable in the case of “LIGNITE” and “NYLON” rollers.
And these tendencies are the same on the length, volume, and weight of rollers too.
