It has been a long history in the world using packing quick lime as desiccant. Currently, the desiccant used in the Chinese market mostly is quick lime and Silica gel, among which quick lime is the large part. Quick lime desiccant has wide Application. It boasts quick absorption speed. As to the foods industry, it can extend 4 to 6 months in the limit of guaranty of products’ quality.
Performance and Features:
Taking quick lime as its major ingredient, it absorbs water depending on the chemical capability. According to the formula, in spite of the air humidity, the desiccant can maintain its absorption ability, which is 32% of its net weight. Given the same air humidity, compared to Silica gel, quick lime desiccant has the advantage of low price, quick absorption speed, low production cost, etc. In addition, combining solidly with water it is free from reabsorbing water. As to the confirmation of water absorption, it is realized by the change of shape from the state of grain to powder.
Application:
It can be widely used in industry of food, costume, tea, leather, shoemaking, equipment, electronic etc.
Theory of Reaction: CaO+H20=Ca (OH) 2
