To place it just, it uses a dual-action procedure in which natural dirt is damaged down by daytime and also is then cleaned away by rainfall, hence making it simpler to maintain clean.
More regarding how it works
Self cleansing glass functions by 2 procedures:
Photo-catalysis - the action of sunshine into the surface area of the glass consumes away dirt. It does this by soaking up the UV component of sunshine which after that damages down any type of natural material on the surface of the glass.
Hydrophilicity - rather of creating beads that run down the home window in rivulets leaving streaks, the rain spreads out as a continuous sheet washing the glass tidy.
Does it constantly work?
Jeff Howell, discovering the benefits, Пълен преглед
and drawbacks of self cleaning glass in The Telegraph (June 27th 2005) wrapped up that self cleaning glass is "self-cleaning as long as it doesn't obtain unclean."
Whilst self cleaning glass surely executed well in lab tests the same conditions seldom use in genuine life. If rainfall is lashing versus one side of the home, the other will undoubtedly stay fairly completely dry and also as a result unwashed.
