Caution
The
product is very easy to be oxidized when exposed
to air and emit sulfur dioxide continuously, so
it is difficult to store the product for a long
time in open air and it is necessary to protect
the product from moisture. The product will
disintegrated when heated above
150℃ and
emit sulfur dioxide gas, so the product cannot
be stored and transported together with
gasoline, acids or oxidants and other
inflammable substances. The product is packed in
internal plastic bags with external braided bags
in net weight of 50 kg. Product for export is
packed in net weight of 25
kg. |
