Cleaning buildings with ... ice water

Moscow-based Pulsar-Engineering, Russia is applying a technique of cleaning and rusting for buildings, buildings or machinery such as turbines and train cars by spraying ice particles through nozzles. straight.

Compared to traditional building cleaning methods using metal or sand-jet nozzles, this new technique offers much more convenience. In fact, old techniques on the one hand can affect the health of users, on the other hand it takes a lot of work and transportation costs, cleaning up sand materials and metal particles.

So the Russian researchers have concluded that ice particles can also be used while ensuring hygiene requirements, which are easier to implement. Moreover, this cleaning method does not affect human health and does not harm the surface of buildings.

This new device is named Gradoboy. Its main mode of operation is based on the creation of ice particles. The ice making machine consists of a sprinkler connected directly to the nozzle. The sprayer will divide the aqueous solution into small particles, freezing it at -70 ° C. When coming out of the spray, these ice particles will take the form of spherical crystals with a size of 300 micro-meters.

Next, they will be sprayed on the area to be cleaned under the impact of compressed air. This spraying process does not affect the quality of water and Gradoboy machine can connect to any type of nozzle. The ice crystals are completely round, without sharp edges that damage the surface to be cleaned.
