METHOD OF PRODUCING COATING ON BLOCK FOAM GLASS Russian patent published in 2019 - IPC C03C17/22 C03C11/00 

FIELD: technological processes.

SUBSTANCE: invention relates to a method of producing coating on block foam glass. Proposed method comprises preparation of charge for coating, its application on face surface of block foamed glass and melting. Charge is prepared in form of 20 % aqueous solution of liquid glass, then 0.5 % of the coloring salt is added to the ready solution, and fusion of front surface of block foamed glass is carried out with plasma torch at power of plasmatron operation of 5 kW and speed of passage of plasma torch along front surface of 0.12 m/s.

EFFECT: high frost resistance and adhesion strength of the coating with foamed glass.
