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  1mm
in maximum, 1mm
to 5mm, 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.
