Сода каустик (люспи и микроперли)
NaOH – sodium hydroxide (caustic soda – flakes and microspheres)
Sodium hydroxide, also known as caustic soda, is an inorganic compound with the chemical formula NaOH. It is a white solid and highly caustic metallic base and alkali salt which is available in pellets, flakes, granules, and as prepared solutions at a number of different concentrations. Sodium hydroxide forms an approximately 50% (by weight) saturated solution with water.
Pure sodium hydroxide is a whitish solid, sold in pellets, flakes, and granular form, as well as in solution. It is highly soluble in water, with a lower solubility in ethanol and methanol, but is insoluble in ether and other non-polar solvents.
Like other corrosive acids and alkalis, drops of sodium hydroxide solutions can decompose proteins and lipids in skin, eyes or other living tissues via amide hydrolysis and ester hydrolysis, which consequently causes chemical burns and may induce permanent blindness if it contacts eyes.Solid alkali may also express its corrosive nature if there is water so protective equipment such as rubber gloves,safety clothing and eye protection should always be used when handling the material or its solutions.
Sodium hydroxide is used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles,drinking water, soaps and detergents and as a drain cleaner.
