Product introduction:Food adjunct/food additive calcium hydroxide slaked lime is roughly made of lime after processed and refined to remove hazard matter like metallic matter.
Calcium Hydroxide Description:
Calcium Hydroxide Food Grade，traditionally called slaked lime, is an inorganic compound with the chemical formula Ca(OH)2. It is a colorless crystal or white powder and is obtained when calcium oxide (called lime or quicklime) is mixed, or "slaked" with water. It has many names including hydrated lime, builders lime, slack lime, cal, or pickling lime. It is of low toxicity. Calcium hydroxide is used in many applications, including food preparation.
1. Molecular formula: Ca (OH)2
2. Molecular weight: 74.096
3. Physicochemical Property:
Soft and delicate white powder with a density of 2.24 and a stacking volume of 0.6-0.8. After 500, hydrate water will lose to become calcium oxide, which absorbs carbon dioxide in the air to form calcium carbonate that can be dissolved in acid instead of water and alcohol.
4. Calcium Hydroxide Food Grade Feature:
High activity, loose structure, great purity (able to be analytically pure), white, fine granulate with few content of foreign matter.
•Manufacturing of Bleaching Powder.
•Process Water Demineralization.
•waste Water Neutralization.
•Neutralization of Acidic effluents.
•Fluxing or Clarifying.
•Drying of mud or sludge.
•Stabilization of hazardous waste.
•Dehairing of Hides in Tanneries.
•Flue gas Desulphurisation.
•Calcium Hypochlorite Bleaching of Paper pulp.
•Detergents drying agent
The produce is widely used in synthesis of medical drug, food additive, hi-tech biological material HA, VC phosphonolipide used as feed additive, food arum, calcium agent, additive for candy manufacturing industry of calcium naphthenate, calcium lactate and calcium citrate, water processing and other high-grade organic chemical industry .
mainly adjust acid wastewater pH value ,widely used for electroplating ,chemical industry , circuit board, pickling, printing&dyeing and paper making wastewater treatment ，Used to remove phosphate , most of the heavy metal and ammonia nitrogen etc.used to adjust up waster pH value of water supply plant.
