Application

YIGYOOLY Hydroxyethylidine Diphosphonic Acid is widely used in water treatment and as a cleaning agent and daily chemical additive in the electronics industry.

YIGYOOLY Hydroxyethylidine Diphosphonic Acid is a scale inhibitor and corrosion inhibitor for boilers and heat exchangers, a chelating agent for cyanide free electroplating, a soap chelating agent, and a cleaning agent for metals and non-metals.

YIGYOOLY Hydroxyethylidine Diphosphonic Acid is commonly used as a scale and corrosion inhibitor in boiler water, circulating water, and oilfield water injection treatment. Often compounded with polyhydroxylic acid scale inhibitors and dispersants. It can also be used as a cyanide free electroplating complexing agent, a color fixing agent for the bleaching and dyeing industry, and a hydrogen peroxide stabilizer.

YIGYOOLY Hydroxyethylidine Diphosphonic Acid is the main material for cyanide free electroplating.

YIGYOOLY Hydroxyethylidine Diphosphonic Acid  is a new type of chlorine free electroplating complexing agent, used as the main agent for stabilizing water quality in the circulating cooling water system, playing a role in corrosion and scale inhibition.

YIGYOOLY Hydroxyethylidine Diphosphonic Acid, As a scale inhibitor, a concentration of 1-10mg/L is generally used, and as a corrosion inhibitor, a concentration of 10-50mg/L is generally used; Generally used as a cleaning agent with a concentration of 1000-2000mg/L; Usually used in combination with polycarboxylate type scale inhibitors and dispersants.
