Product Description
Shenzhen DMF free colloidal silica gel for concrete
Product description
Silica gel desiccant is a highly active adsorption material. It is usually made of reacting with sodium silicate and sulfuric, aging as well as acid bubble. It is insoluble in water and any solvents. Non-poisonous and tasteless, chemical stability. It won't react with any materials except alkali and hydrofluoric acid.
Advantage
100% natural degradation, saturated moisture absorption reach 30%, maximum duration last 1 year.
Characteristic
Silica gel is a high absorbent. Exposing in the air (RH 80%-90%, 25° C) 7 hours, it can absorb 35-39% water. The silica gel is made by people with the Na2SiO2 and chemical relative. The character is a lot of holes in inner, the outside structure is the anomalistic graininess. The inner configuration makes many hiatus net, forming the effect of capillary absorbent and coagulating. So it can absorb the surrounding water, alcohol, hydrocarbon and any other chemical molecules. People use sio2 physical character and now make it the best absorbent.
