Calcium Chloride
CAS No. 10043-52-4
Granular anhydrous calcium
chloride of JUHUA brand is manufactured with the
raw materials of high quality calcium carbonate
and salt and through several processes of reaction
synthesis, filtering, evaporation, concentration
and drying. The exterior appears in the form of
block and grain (The grain size varies ø1mm
in maximum, ø1mm toø5mm, and 5mm in
minimum.)
Molecular formula:
CaCl2
Molecular weight: 110.99
Usage: Granular anhydrous
calcium chloride can be used as drying agent for
drying nitrogen, oxygen, hydrogen, and sulfur dioxide
gases. It also can be used as dehydrating agent
in producing alcohol, ester, ether and propylene
resin. Hydrotropic solution of calcium chloride
is the important cryogen for refrigerator and ice
making. It is also a good anti-freeze agent and
agglomerating agent in construction for concrete
hardening and cold hardiness of sand mortar. It
can be antifogging agent in harbors, dust collection
agent of road surface, fire-proofing agent of fabrics,
protective agent and fining agent of aluminum and
magnesium metallurgy, precipitant for lake pigments,
raw materials for de-ink of waste paper and calcium
salt. Hydrotropic solution of calcium chloride is
the best flame retardant agent, which could be used
in fields of preparing barium chloride, treating
water in boilers, manufacturing calcium metal, fabric
gluing, road treating, coal treating, leather making
and pharmaceutics.
Quality index: it is in accordance with the state
enterprise standards Q/JHGS 15-2002 (industry),
Q/HYGS 003-1999(reagent)
Grain size grade varies in 3 specifications: 1mm
in maximum, 1mm to 5mm, and 5mm in minimum.
