Refined adsorbent aluminum magnesium carbonate (commonly known as hydrotalcite). The
appearance is a kind of white porous srical particles or powder with good flowability. It belongs
to amteric compounds. The product has the functions of deacidification, deodorization,
decolorization, adsorption of potassium, sodium ion and filtration medium. As polyether refined
adsorbent, it has exnt adsorption and decolorization properties. Used in the last process of
polyether polyol production.
Production application: the crude polyether polyol was put into the neutralization kettle. A small
amount of pure water is added at a certain temperature. the neutralization reaction was carried out
after stirring. The solution is controlled to a given value. Hydrotalcite is added at the same
temperature. The solution is kept at the temperature for 1.5~2 h before vacuum distillation for
dehydration. A filtration cycle doesn’t begin until the water content reaches a given value. The K+ (Na+ )
ion content of the solution is determined until it reaches a given value. The solution is filtered
immediately, and the filtrate is clear and transparent polyether.
Packaging, transportation, and storage: outer coating paper, ft composite paper and soft
plastic bags. Net weight 10kg/ 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.
