Sulfamic acid, 25 kg

A hard crystalline acid built for descaling and metal surface treatment

The 25 kg package is aimed at facilities that consume this reagent regularly and in bulk - industrial cleaning services, water utilities, heating plants, metalworking shops, and detergent manufacturers. This compound belongs to the category of Acids, Salts, Alcohols, and Alkalis, where fundamental chemical compounds for industrial and laboratory use are gathered, and it stands out within that group for its solid crystalline form - unlike many strong acids it does not fume in air, is gentler on metals, and is easier to store and dose precisely.

The primary application is removing limescale and mineral deposits from the inner surfaces of boilers, heat exchangers, evaporators, and industrial dishwashing or laundry machines. The solution dissolves carbonate and oxide deposits effectively while treating the base metal much more gently than hydrochloric or sulfuric acid would, reducing corrosion risk and extending equipment lifespan. In textile manufacturing the acid serves as a mordant during dyeing and as a component of bleaching formulations, while in metalworking and electroplating it is used for pickling and surface preparation before coating application. The reagent also appears in flame-retardant treatments, in photographic fixing solutions, and in some industrial cleaning products designed for plumbing fixtures and appliance descaling.

Working solutions are typically prepared at concentrations between 5 and 20 percent in water, depending on how heavily the surface is fouled. The acid dissolves readily in warm water - heating to 40-60 degrees noticeably speeds up the reaction with carbonate scale, though a cold solution can also be used with a longer exposure time. It should not be mixed directly with alkaline reagents such as sodium hydroxide, since the neutralization reaction is vigorous and releases significant heat, so such processes are kept separate and temperature-controlled. Many production lines pair this reagent with other acids from the same category, such as lactic acid for gentler processing steps, or ascorbic acid as a reducing agent in specific technological operations.

The crystalline material should be stored in sealed containers, in a dry and cool location, away from direct sunlight, alkalis, oxidizers, and chlorine-containing compounds. Under proper storage conditions the product retains its activity for a long time. When handling concentrated solutions, hand and eye protection is recommended, and the working area should be well ventilated.

The 25 kg package size is intended for continuous and semi-industrial production runs, where consistent raw material supply and precise batch calculation over long production cycles matter far more than one-off laboratory testing.

Descaling concentrate for industrial heat exchangers

Sulfamic acid 1500 g

Process water 10000 ml

Corrosion inhibitor 15 ml

Gradually add the acid crystals into water preheated to 50 degrees while stirring continuously until fully dissolved, then add the corrosion inhibitor to protect the metal surfaces of the equipment. Circulate the finished solution through the heat exchanger loop for 40-90 minutes depending on the amount of scale buildup, then flush the system thoroughly with clean water to remove all reagent residue.
