1. Characters
Melt white grain or stripes are often made into small flakes.
Easy to absorb moisture and carbon dioxide in the air. 1g soluble
in boiling water 0.9ml water chiller, 0.3ml, 7.2ml, ethanol,
4.2ml, methanol, soluble in Glycerin. Soluble in water, ethanol,
or when solution when mixed with acids produced theatrical heat.
Solution is strongly alkaline. The relative density of 2.*3. **8
° c melting point. ***0 ° c boiling point. Half of the deaths
(mice, Intraperitoneal) *0mg/kg. Corrosive. Its aqueous solution
a puckery taste and creamy. Sodium hydroxide for carbon dioxide
absorption, as well as biological experiment commonly used
chemicals. Water absorption, so often certain neutral or alkaline
gas desiccant such as: O2,H2,NH3.
2. Uses
the wider use of wastewater treatment chemicals, basic analytical
reagent, the preparation of analyses by standard alkaline liquid,
a small amount of carbon dioxide and moisture absorption agent,
and sodium salt of the acid manufacture. Manufacture of other
reagents containing hydroxyl ions; in paper-making, printing and
dyeing, waste water treatment, electroplating, are important uses
of chemical drilling; domestic brands: tianhui card, sky card,
gold card. Sodium hydroxide is a good catalyst for many organic
reactions.
3. Security measures
Sealed packaging, store in a cool dry place. With acids, ammonium
class, easy (can) fuel such storage and distribution. Not come
into contact with skin, skin (eyes) contact, rinse with flowing,
applying boric acid solution. If eating, gargle with water,drink
milk, soy milk or egg whites (and other acidic food-friendly) and
need to seek medical advice immediately.
