Sodium Fluorosilicate Production

Product Name:

Sodium Fluorosilicate Production

Product model:
Product introduction:

Detailed description

Sodium Fluorosilicate Production can be used as the insecticide in agriculture, the milky agent of enamel, the corrosion production agent of opal glass, wood preservatives and the raw material for the production of other kinds of fluoride as well as being applied to the smelting of beryllium and aluminum and pharmaceuticals, leather and rubber industry. In the refractory material, it can be used as the coagulant as the water glass binding agent.

Sodium Fluorosilicate Production has a low water solubility, it reaction with the water glass is slow and gradual. This can not only boost the construction but also has a high density and strength of the cured products. It is most commonly used in the inorganic material binding with the water glass.

Sodium Fluorosilicate Production information is edited by Xiongfeng Dai from Chemicalbook.This product is toxic with stimulation effect on the respiratory organ. People of mistakenly oral poisoning will get severe symptoms of damage to the gastrointestinal tract with the lethal dose being 0.4~4g. During the working of the operator, they should wear the necessary protective equipment to prevent poisoning. Production equipment should be sealed and the workshop should be well ventilated.Calcium superphosphate byproduct method: use sulfuric acid and ground phosphate rock for production of superphosphate or fluorine-containing waste gas during extraction of phosphate with water absorbing silicon tetrafluoride to make it into fluorosilicate.

Sodium Fluorosilicate Production concentration of fluorine acid solution reaches 8% to 10%, stand static for clarification and remove the impurities with the clarified fluorine silicate solution being added of sodium chloride (being excess of about 25%) for reaction of sodium fluorosilicate. Further go through centrifugation isolation, washing, air drying at a temperature below 300 ℃ and then pulverize to obtain the finished product of sodium fluorosilicate.H2SiF6 + 2NaCl → Na2SiF6 + 2HCl
