Sulfamic acid H3NO3S Colorless or White crystalline Can be used as
a cleaning agent
Product Introduction:
Aminosulfonic acid is an inorganic solid acid formed by replacing
the hydroxyl group of sulfuric acid with an amino group. Its
chemical formula is NH2SO3H, molecular weight is 97.09, and it is
generally a white, odorless oblique square shaped crystal with a
relative density of 2.126 and a melting point of 205 ℃. It is
soluble in water and liquid ammonia, and at room temperature, as
long as it remains dry and does not come into contact with water,
the solid aminosulfonic acid is non hygroscopic and relatively
stable. The aqueous solution of sulfamic acid has the same strong
acidity as hydrochloric acid, sulfuric acid, etc., so it is also
known as solid sulfuric acid. It has the characteristics of non
volatility, no odor, and low toxicity to the human body. Dust or
solution is irritating to the eyes and skin and can cause burns.
The maximum allowable concentration is 10mg/m3. Aminosulfonic acid
can be used to synthesize herbicides, fire retardants, sweeteners,
preservatives, metal cleaning agents, etc. It is a common chemical
raw material.

Product Usage:
1.Cleaning agent
Amino sulfonic acid cleaning agent has a wide range of applications
and can be used to clean boilers, condensers, heat exchangers,
jackets, and chemical pipelines. Use it to remove scale from glass
lined storage tanks, pots, open beer coolers, and beer barrels in
breweries; Cleaning evaporators in enamel factories and equipment
in paper mills; In terms of air conditioning, it can remove rust
and scale from the cooling system and evaporative condenser; It can
be used by sea vessels to remove seaweed and scale from seawater
evaporators (distillation equipment), heat exchangers, and
saltwater heaters; Can clean the scale of copper pots, radiators,
dishwashing mechanisms, silverware, flush toilets, ceramic tiles,
food and dairy processing equipment; It can remove protein deposits
on steamers and sediment on disinfectants used in fresh meat,
vegetable, and cheese processing plants. The US Department of
Agriculture permits the use of sulfamic acid as an acidic cleaning
agent in fresh meat, poultry, rabbit, and egg processing companies.
2.textile industry
Aminosulfonic acid can be used as an eliminating agent for excess
nitrite in diazotization reactions in the dye industry, a color
fixing agent for textile dyeing, to form a fireproof layer on
textiles, and can also be used to produce yarn cleaning agents and
other additives in the textile industry.
3.Paper Industry
Aminosulfonic acid can be used as a bleaching aid to reduce or
eliminate the catalytic effect of heavy metal ions in the bleaching
solution, thereby ensuring the quality of the bleaching solution
and reducing the oxidative degradation of fibers by metal ions. It
can also prevent fiber peeling reactions and improve pulp strength
and whiteness.
4.petroleum industry
Aminosulfonic acid can be used to unblock oil reservoirs and
increase their permeability. Injecting a solution of aminosulfonic
acid into a carbonate rock reservoir can avoid the deposition of
salt due to the easy reaction between aminosulfonic acid and the
reservoir rock. The processing cost is slightly higher than using
hydrochloric acid, but the oil production is doubled. The United
States uses 48.5% potassium hydroxyacetate and 3.4% sulfamic acid.
A 0.1-3% aqueous solution of wetting agent is used to clean the
gypsum scale layer in the oil well casing, with a treatment time of
about 30 hours.
5.Agriculture
Aminosulfonic acid and ammonium aminosulfonate were initially
developed as herbicides. It is said that when applied directly to
plants, they have a toxic effect; And when applied to the soil, it
has a male killing effect. In the 1978 experiment on the male
killing effect of amino sulfonic acid on rice conducted in
Guangdong Province, China, the efficacy was better than other
salts. Spraying at a concentration of 0.05% to 0.5% resulted in a
male killing rate of 95% to 100%. However, the efficacy was not
stable enough and there were drug hazards. The herbicide
concentration of sulfamic acid is usually 75 g/L of active
ingredient.
