Magnesium sulphate heptahydrate
Content: 99.5%
Size: 1-3mm or 2-4mm
Solubility: 500g/1L water
I.Production description:
Name: Magnesium sulphate fertilizer content 99.5%;
Size:1-3mm, small granule which is not easy to caking, free flowing appearance.
Usage:
1) Magnesium sulphate heptahydrate is an auxiliary raw material for papermaking,
printing and dyeing industries. Magnesium salts (including magnesium sulfate) play
a role in protecting cellulose during oxygen bleaching of pulp because they can passivate
the catalytic metal ions contained in the pulp.
2) Most of Magnesium sulphate fertilizer content are used for agriculture fertilizer, also
can add our products into water soluble fertilier in order to have enough magnesium
element to crops.
II.Process before delivery the Magnesium sulphate:
1. Usually our package is 25kg bag, before delivery, we will pick up 10 bags to weight, in order to sure
95% weight can up to 25tons.
2. Randomly select 20 bags to check whether the sealing of the packaging machine is complete to
ensure that the product does not leak.
3. If there are labels on the small bags, 20 bags will be randomly selected to check whether the labels
are firmly affixed, and an additional 50 labels will be prepared during shipment to avoid falling off problems
III. Test process for mangesium sulphate fertilizer content water solubility:
As standard requires, the water soluble of Magnesium suphate is 500g/1L water, when we test,
we will use 6g heptahydrate into 100ml water, the water will be very clear and with less impurity.
Because magnesium sulfate is mostly used for plant irrigation or foliar fertilization, while in foreign
countries, many customers use sprinklers produced in Canada. If there are many impurities, it can
easily lead to clogging of the sprinklers, affecting the service life of the sprinklers。
IV. The loading of Magnesium sulphate:
When we exported to South America, in order to save the sea freight, the customer always choose
the 40NOR to load, there will be 28.5 tons/40NOR.
