STEAM-GENERATING DEVICE PROVIDED WITH HYDROPHILIC COATING Russian patent published in 2013 - IPC F22B31/00 D06F75/18 

FIELD: chemistry.

SUBSTANCE: steam-generating device has a steam chamber coated with a hydrophilic coating. The hydrophilic coating contains an alkali metal silicate and boron, preferably a salt of boron with a metal. The metal is alkali metal lithium and/or potassium. The alkali metal silicate is sodium silicate. The amount of the salt of boron with a metal is preferably between 1 wt % and 40 wt % of the entire composition of the dry coating. The hydrophilic coating contains silicon dioxide particles. The coating promotes steaming and is resistant to flaking. The method of producing a hydrophilic coating in the steam chamber of a steam-generating device involves preparing a mixture of an alkali metal silicate and a salt of boron with a metal, feeding the mixture into the steam chamber and curing the mixture at a high temperature to form an acid-resistant hydrophilic coating. The mixture is brought to the high temperature by heating the surface of the steam chamber. A steam iron has the described steam-generating device.

EFFECT: improved device.
