5.Properties:white crystal with luster,
taste sour, capable of decomposing when heated, soluble in water,
and also can produce complex compound with many metal and inorganic
salts. 6.Application:designed
as the thiazole drug (such as sulfamoxole, tetramisole), and
intermediate of medicine for checking thyropathy; in textile
industries, they can be used as bleacher, dyeing aids and anti
oxidation agents; In blue-print paper, it features in clear
line, and color fading resistancy; In photography, it serves
as the stablizer for development and fixing; in gold extraction,
as the substitute of heavily poisonous cyanide; in electroplating,
add some into the zinc and barium electroplating trough to well-mixing
the metal deposit, enhance the stablity of the electroplating
liquid and ensure uniform luster on the surface of the plated
pieces; to clean the filth in the high pressure boiler; or as
the efficiency enhancer of the nitrogenous fertilizer, etc.. 7.Packing:Packed
by PVC membrane bag, each of them net weighting 25kg.
