ZINC CARBONATE
Molecular formula:ZnCO32Zn(OH)2H2O
Synonyms: Basic zinc carbonate; zinc subcarbonate; carbonic acid, zinc salt (1:1) | MAIN INDUSTRIES WHICH ARE USING ZINC CARBONATE: | | Our high purity zinc carbonate is widely used by many industries: | | - in animal feeds as a micronutrient and for the treatment and prevention of swine parakeratosis due to zinc deficiency; | | - in the rubber industry; | | - in the preparation of paints as an active agent; | | - in the ceramics industry as a pigment; | | - in the catalyst industry; | | - in the cosmetics and pharmaceutical industry for the preparation of lotions and creams. |
The zinc carbonate, white slight non-stereotype powder froth, can not dissolve in water and mellow, slightly soluble in the ammonia. It can completely dissolve in the diluted acid and the sodium hydroxide (NaOH).
It is used not only in activating transparency agent, strengthening agent and coloring agent in the rubber industry , but also massively in the rubber connection agent . Apart from that, it also can used in petroleum and well drilling industry .
Zinc carbonate is used as a raw material for catatyst, desulphurization, rubber and emulsion activator ctc.
Applications
Under
has
otherwise,
Zinc carbonate is effective as a scavenger at the pH levels found in drilling fluids. It is
recommended that a pH above 10 be maintained whenever H2S is expected. This high alkalinity
converts
(>10)
The initial treatment of
zinc carbonate is usually 1.5 to 3 lb/bbl (3.75 to 8.0 kg/m3), depending on
requirements.
of
One hundred kilograms (kg) of
zinc carbonate reacts with approximately 25 kg of hydrogen
sulfide.
carbonate
The product has a fine particle size and good dispersibility which minimizes reaction time. Packaging
Zinc
local
Store in a dry location away from sources of heat or ignition, and minimize dust. Zinc carbonate can irritate the respiratory tract, the effect being that of a mild alkali. Some soreness and coughing are symptoms.
