formula：Na2O.SiO.XH2O X:O,5、9 |
■ This product possesses
high alkaline and defoul character, which is easy to
soluble in water, good dispersibility and emulsifiability,
not soluble in alcohol. It will deliguesce after absorbing
moisture and carbon dioxide from the air.
■ This product is mainly
used in making high efficiency detergent and metal cleaner.
Instead of STPP, it can raise cleaning |
|
efficiency and reduce environmental pollution, provides
excellent alkaline buffer, corrosing prevention for
metal (i.e. Zinc, Aluminum), possesses the character
of softening water.
■ Sodium measilicate pentahydrate
and nonanhydrate types are white crystalized powder.We
possess the capacity of 1,500MT per year.
■ Sodium metasilicate anhydrous
is white beaded, solid.The production line is introduced
from PQ Corp,.USA. The capacity is 10,000MT per year.The
line is the sole one in China. |

This
product is developed by our company using the advanced product
standard from abroad for reference. Compared with product of
same kind in China, it possesses the character of size uniform,
good dispersivity and solubility, emulsifiability.
It has high alkaline and defoul ability, which is easy to
soluble in water, but not in alcohol.It will deliquescence afe\ter
absorbing moisture and carbon dioxide from the air.
This product is mainly used in making high efficiency detergent
and metal cleaner.Instead of STPP.it can raise cleaning efficiency
and reduce environment plllution, provides excellent alkaline
buffer,corrosion prevention for metal(i.e Zinc, Aluminum),and
function of softening water. |
