Applications：Standard of alkali titration, complexing masking agent, standard of nitrogen and sulfur determination by organic microanalysis, preparation of rust remover, fabric fire prevention, organic synthesis. Sulfamic acid as a cleaning agent, because it is solid, with storage, transportation convenience, easy preparation and many other advantages, especially suitable for long distance use. Sulfionic acid is cheap and easy to obtain and good stability of solid acid, esterification reaction of organic acid has a good catalytic effect, and does not corrosion equipment packaging: 25kg plastic woven bag lined with plastic packaging, storage and transportation to prevent the sun and rain, do not mix with sharp things, to be stored in a clean dry warehouse, to prevent moisture. 250kg, 500kg, 1000kg plastic woven bags lined with plastic packaging, storage and transport to prevent the sun and rain.
Storage and Transportation：stored in a clean and dry warehouse, anti sun and rain, anti moisture, do not mix with sharp objects. Use plastic bags for packing. Store in a cool, ventilated and dry place. Store and transport according to general chemical regulations.
