Refined adsorbent magnesium polysilicate, molecular formula: xMgO·ySiO2·nH2O. The
appearance is a kind of white porous spherical particles or powder with good flowability. It belongs
to amphoteric compounds. The product has the functions of deacidification, deodorization,
decolorization, adsorption of potassium, sodium ion and filtration medium. As polyether refined
adsorbent, it has excellent adsorption and decolorization properties. Used in the last process of
polyether polyol production. Its action principle is to form large particle size composite salt
crystallization and small solubility in polyether product to filter and remove through the combination
of the absorbent and metal ions, and at the same time make use of its porous structure to achieve
decolorization and deodorization effect.
Product application: the crude polypropylene oxide polyol was put into neutralization kettle, a small
amount of pure water was added at a certain temperature, neutralization reaction was carried out after
stirring, PH value of neutralizing solution was controlled within the index, and then 0.1~0.3%
magnesium polysilicate adsorbents were added at the same temperature, dehydration was carried out
while stirring, dehydration rate was controlled, KH2PO3 crystal grow evenly at first and then
quickly.
When the water is removed to the prescribed requirements, the filtration cycle is carried out, the K+（Na+）ion content of the circulating liquid is analyzed, and the filtration is carried out immediately
when it meets the requirements. The filter solution is a clear and transparent polyether .
Packaging, transportation, and storage: outer coating paper, lined kraft composite paper and soft
plastic bags. Net weight 20kg/bag.
Requirements: light loading, light unloading, rainproof, moisture-proof. Products that have not been
used up after opening the bag must be wrapped and sealed
