규산소다 화학적 특성, 용도, 생산

물성
점도
- 액상규산나트륨의 점도는 몰비, 농도, 온도에 따라 변화한다. 농도가 높으면 점도가 올라가고 온도가 상승하면 점도는 낮아진다. 또한 같은 농도에서 몰비를 높이면 점도는 상승한다.
pH
- 액상규산나트륨의 pH는 보통 11.5～13.0 에서 생산된다.
- 그리고 몰비와 농도에 따라 다르게 나타나며, 몰비가 낮을수록( 함량이 높을수록) pH는 높아진다.
용도
액상규산염은 지관, 합지 및 기타 여러 가지 재료의 접착제로 사용되고 있습니다. 액상규산나트륨은 초기 작업성 및 접착성, 접착강도가 우수한 경제적인 접착제입니다.제지산업에서 액상규산나트륨은 탈묵제(de-inking), 사이징제,코팅제, 표백제로 사용되고 있습니다.
개요
Sodium silicate, 2Na2OSiO2, is the simplest form of glass. It is found as lumps of greenish glass soluble in steam under pressure, white powders of varying degrees of solubility, or liquids cloudy or clear. It is noncombustible; however, when the powdered form is suspended in air, it could cause a dust explosion if an ignition source is present. Breathing the dust may also cause health problems. The glass form could also create a hazard to responders in an accident. It is not listed as a hazardous material in the DOT Hazardous Materials Tables. The primary uses are as catalysts, soaps, adhesives, water treatment, bleaching, waterproofing, and flame retardant.
화학적 성질
Sodium silicate,NA2Si03 also known as a liquid glass, silicate of soda, sodium metasilicate, and soluble glass, is a grayish-white crystalline powder that has a melting point of 1088 °C (1990 °F). It is soluble in water and has strong detergent and emulsifying properties. Sodium silicate is used to fireproof textiles, insulate electric wire, protect wood and porous stone, grease proof paper containers, and as a catalyst in refining high-octane gasoline.
용도
Sodium Silicate is a product used as a preservative for eggs.
정의
ChEBI: An inorganic sodium salt having silicate as the counterion.
공업 용도
Sodium silicate (liquid silicate, metso or sodium silicate beads) has the general formula Na₂SiO₃. The liquid silicates (“O” and “N” brand) are clear, thick liquids, while silicate powder is a granular, white substance. Sodium silicate is a mixture of sodium or potassium salts. Sodium silicates are primarily used in mineral flotation practice.
Toxicology
Aqueous solutions of Sodium Silicate species are a part of a chemical continuum of silicates based on an equilibrium of alkali, water, and silica. This compound, administered orally, is readily absorbed from the alimentary canal and excreted in the urine. Dogs fed 2.4 g/kg/day of Sodium Silicate for 4 weeks had gross renal lesions but no impairment of renal function. It was a severe eye irritant in some eye irritation studies but was irritating or nonirritating in others. A skin freshener containing Sodium Silicate was nonirritating. Rats given Sodium Silicate (600 and 1200 ppm of added silica) in the drinking water in reproductive studies produced a reduced number of offspring: 67% of controls at 600 ppm and 80% of controls at 1200 ppm[1].
Purification Methods
Sodium silicate solution [1344-09-8] pK 1 9.51, pK 2 11.77 (for silicic acid, H4S i O4) Purify by contact filtration with activated charcoal.
