Silica as anti-caking agent is a white fluffy powder,
it can prevent powder from agglomeration problem due to moisture
At the same time,it has function of absorption.
Mainly added to the particles, powdered food to prevent particles
or powdery food gathering agglomeration, to keep its loose or free
Package and storage
1. Package : 10 kg / PE or Paper bag
Standard packaging includes small bags, paper bags, cartons, or
flexible intermediate bulk containers (FIBCs) in order to meet
specific customer needs.
2. Storage : Kept in a low temperature, dry and ventilated place,
avoid direct sunlight.
The feed silicate should be stored in a ventilated, dry and cool
space, away from direct sunlight, mositure and flames.
It shoud not be mixed with other materials, and should be storedd
at less than 40℃.
The warranty period is 12 months, from the date of manufacturing.
After 12 months, a re-detemination of the moisture content should
be done. To ensure it is safe to use, all data must be in
compliance with health standards, though we do not recommend using
the precipitated animal feed silica outside the warranty period,
3. Shelf life: One year in ventilating, cool and dry area.
2.What is hydrated silica?
Hydrated Silica (English name Hydrated Silica;
Silicondioxidehydrate), also known as white carbon black , also
known as light silica, the main component is silica, white
amorphous powder. Light Loose, soluble in caustic and hydrofluoric
acid, insoluble in water, solvents and acids (except hydrofluoric
acid). High temperature, nonflammable, tasteless, odorless, with
good electrical insulation. Its performance is similar to carbon
black , but it is white.The molecular formula and the structural
formula can be represented by SiO2 · nH2O, where nH2O is present as
a surface hydroxyl group. Its macroscopic structure is similar to
carbon black, the particles are spherical, single particles between
the surface contact, was chain-like structure . Chain structure and
hydrogen bond force to form a group of aggregates. The original
particles are very fine, absorb moisture in the air to form
aggregated fine particles. Silica particles on the surface of
hydroxyl particles, mainly isolated hydroxyl, adjacent hydroxyl,
silicon three . Wherein the adsorption of polar groups from
adjacent hydroxyl groups is important. The presence of thes
