As you mentioned, the rings of Saturn are made of ice chunks (and some rocks) that range in size from the size of a fingernail to the size of a car.

The mean temperature on Saturn, at the top of the clouds, is 88 degress Kelvin (-185 C; -290 F).

Since this temperature is significantly below the temperature required to turn ice into water or water vaopr, we can conclude that this is the reason that the rings are static.

To get evaporation, you typically need some heat. There’s no atmosphere in space where the rings are located, so they’re not getting much heat.

Also, the rings stay in their shape because of gravity — they’re locked into an orbit around the planet, just like its moons.

ahh…good question. Probably for the same reason there are no “clouds” in space. It’s too cold in space for the ice to melt, and if it doesn’t melt, it can’t evaporate.
