Soda Ash (Sodium Carbonate) Na2co3
Product Description
Appearance: White powder, is solid
Taste: Acerbity
The relative density (water = 1)
Melting point: **1Degrees Celsius
Solubility: *1g *0 Degrees Celsius
Stability:
Stability stronger, but high temperatures also can decompose,
generating oxidation sodium and carbon dioxide. Long-term exposure
to air can absorbs moisture from the air and carbon dioxide,
generating sodium bicarbonate, and form lumps. Hygroscopic very
strong, very easy to form lumps, at high temperatures also does not
decompose.
Solubility:
Soluble in water, soluble in anhydrous alcohol, insoluble in
propanol. Sodium carbonate is soluble in water, is a kind of alkali
salt, soluble in water occurs after hydrolysis reaction, make
explicit alkaline solution, has certain corrosive, can with acid on
neutralization reaction, generating the corresponding salt and
releasing carbon dioxide.
Use:
Is one of the important chemical raw materials, for making
chemicals, cleaning agents, detergent, also used in neuroscientists
have and making pharmaceuticals.
Most used in industry, a small part for civilian use. In industrial
use soda, mainly is light industry, building materials, chemical
industry, accounting for approximately 2/3; Followed by
metallurgical, textile, oil, national defense, pharmaceutical and
other industries. Glass industry is the biggest soda consumption
departments, every tons of glass consumption soda 0.2 tons.
Chemical industry for making the sodium silicate, sodium
dichromate, sodium nitrate and sodium fluoride, baking soda, borax,
trisodium phosphate, sodium etc. The metallurgical industry as
smelting flux, dressing collectorless flotation agents, steelmaking
and refined antimony used desulphurization agent. Dyeing industry
as soft agent. Leather industry for raw material leather
degreasing, neutralization chrome tanning and improve chrome tanned
liquid alkalinity. Also used in the production of synthetic
detergent additives sodium tripolyph-osphate and other sodium salt,
etc. Consumption level of soda for the production monosodium
glutamate, pasta, etc.
Health hazard:
This product has the weak stimulating and weak corrosive. Direct
contact can cause skin and eye burns. Production of inhaled its
dust and smoke can cause irritation to the respiratory tract and
conjunctivitis, still can have nasal mucosa ulcer and atrophy and
septal perforation. Long time to contact the product solution can
happen eczema, dermatitis, corn shape ulcer and flabby skin.
Contact with the product of exposed workers in respiratory diseases
increased incidence. Accidental can cause gastrointestinal burns,
mucous membrane debaucjed, bleeding and shock.
Operation caution:
Airtight operation, strengthen ventilated. Operators must receive
special training, strictly abide by the procedures. Suggest
operators wear for self-inhalation filtertype dust respirator wear
safety glasses, chemical, wear antivirus content overalls and wear
rubber gloves penetration. Avoid creating dust. Avoid contact with
acids. When carrying light light discharge, prevent packaging and
vessel damage. Equipped with emergency treatment equipment. Leakage
Empty containers may remain hazards. Dilution or preparation,
should put alkali solution to the water, avoid boiling and
splash.
Storage precautions:
Store in a cool, well ventilated area. Away from fire and heat
source. With the acid etc should be stored apart, avoid by all
means is mixed shop. Storage areas shall be equipped with
appropriate materials asylum leakage.
