Introduction:
Nano-technology
is now the world research and the development
hot spot, but nano-technology and the material
still were at the start stage in our country,
the majority of achievements also paused in
the laboratory stage, the true technology was
mature, enters the industrial production and
the application only then the minority several
varieties, nanometer active calcium carbonate
was one kind.
Nanometer active calcium carbonate is one kind
of new functional packing material which the
1990s develops, the particle size betwen
1-100nm, as a result of granule suprefine, its
crystal structure and the surface effect which
the ordinary calcium carbonate does not have
and macroscopic then says the effect, thus has
a series of fine physics and chemistries
performance. Compares with the ordinary
calcium carbonate product, because its product
quality and the performance all had improved
greatly, caused it to be possible to play in
the multitudinous application domain to the
enhancement, the plasticizing role, from the
surface change application product
workability, usability and the outward
appearance, might partially substitute for the
carbon black, the white carbon black and the
titanium oxide powder and so on the experisive
raw materia, caused the product cost to drop,
quality large scale enhancement. Therefore,
nanomter calcium carbonate appearance,
displays the widespread serviceability and the
more exuberant market demand, widely applies
in domain and so on coating, plastic, rubber,
adhesive, papermaking, printing ink, cosmetics
and medicine.
Technology
Introduction:
Our company uses the
Beijing chemical industry university Ministry
of Education country ultra gravity engineering
research center development the ultra
gravitational method synthesis nanometer
calcium carbonate technology, the use high
speed revolves produces compared to the
terrestrial gravity acceleration high several
hundred time of ultra gravities environment,
effectively controls the chemical reaction,
the crystallization process in the molecular
criterion, thus obtains the granularity to be
small, the distributed even high grade
nanometer calcium carbonate product. Its
average grain diameter is 15-40nm, in the
combined sequence does not join any crystal
control reagent, the product purity high, the
crystal rule, the quality is stable. This
technology has attained the national invention
patent, the method and the technology is the
international origination, was recognized by
the domestic and foreign experts, the
technical level is in the international
leading level.

characteristic
1¡¢Grain
of carefulness: The particle size is
between 15-40nm, is smaller than by far
the ordinary calcium carbonate, alst the
distribution is even.
2¡¢The
relative surface accumulates in a big
way: >=40©O,
ordinary calcium carboante is bigger
than server dozens even several hundred
times.
3¡¢Crystal
rule: The granule crystal form for sets
up the square shape, also is extremely
neat.
4¡¢Activeness
high: The surface passes through special
activation processing, activation
>=95%, the packing compatibility is
good.
5¡¢Albedo
high: The albedo >=95%, is suitable
extremely for the tinted product.
6¡¢Moistrue
low: The moisture <=0.3%, affects
slightly to the original packing body.
8¡¢The
PH value reveals the weak basicity:
PH=8.5-9.5. |
