Calcium hydroxide Industrial Grade

Food-grade calcium

A, molecular formula: CaO

Second, the molecular weight: 56.08

Properties: white or gray block or particles, easy absorption of moisture in the air and carbon dioxide. Easy digest, under the influence of water to generate calcium hydroxide, and release a lot of heat.

Four, purpose: according to the standard GB 2760-2007 "hygienic standards of using food additives" regulation allows calcium oxide is used as the food industry with acidity regulator, nutrients, flour conditioner and starter cultures.

Five, the main technical indicators (GB 30614-2014)

The calcium oxide as a packaging desiccant has a long history in the world, because of its moisture absorption capability is strong, and low cost, use lime desiccant is very respected in the international market. Quick lime desiccant is widely used in food, clothing, tea, leather, shoes, electrical appliances, precision electronics, ocean transportation, and other industries, has excellent dry moisture absorption effect. To apply the food industry, can make the food shelf life extension of 4 to 6 months.

Quick lime desiccant (CaO) as the main component is calcium oxide, absorb water through chemical properties. Conghua reactive, regardless of the outside air temperature, this product can keep the weight of 32% moisture absorption ability. In the same conditions of humidity of the air, it than silica gel by physical properties such as the moisture absorption of dry material, more suitable for low temperature preservation, common to the food industry, can make the shelf life of food extended 4 to 6 months. In addition, due to the combined with calcium oxide and water is very strong, so can not to release the moisture. About the confirmation of moisture absorption is composed of quick lime desiccant particles into a powder from the shape change.
