Place of Origin:
Potassium nitrate is a strong oxidant. Contact with organic matter can cause combustion and explosion. Therefore, potassium nitrate should be stored in a cool and dry place away from fire and heat source. It is forbidden to store and transport together with reducing agent, acid, combustible material and metal powder.
Industrial potassium nitrate is an important inorganic chemical raw material, which belongs to controlled products and generally appears as white particles or crystalline powder. Potassium nitrate (strontium carbonate) manufacturers, in order to prevent air flow entraining droplets from causing high-purity industrial potassium nitrate_ For the material loss of industrial potassium nitrate, the air cooling crystallization device adopts a reasonable liquid distribution device and wind speed. In addition, a liquid catching device is added to control the supersaturation of the solution and accelerate the convection diffusion of the solution during the air cooling crystallization process, so as to precipitate the industrial potassium nitrate crystal product with large grains.
At the same time, the potassium nitrate manufacturer adopts the two effect evaporation process, changing the original two external circulation evaporators to the two effect downstream evaporation process. During evaporation, the steam from the boiler enters the primary effect evaporator for heating and evaporation, and then enters the secondary effect evaporator for steam heating. The steam and condensate from the preheater are separated from the condensate by the steam water separator, then enter the condenser for condensation, and then go to the vacuum system for vacuum pumping to maintain the negative pressure in the two effect evaporator.
1.Photoelectric grade potassium nitrate is mainly used for chemical strengthening of high-end glass. The viscosity of potassium glass is greater than that of sodium glass, which can reduce the crystallization tendency of glass and increase the transparency and gloss of glass. Potassium nitrate can be used as a good hardening material for tempered glass to enhance hardness and increase the ability to resist falling.
2. Agricultural potassium nitrate fertilizer is a pure plant nutrient, which is completely soluble in water without residual harmful substances. The nitrate nitrogen and potassium contained in it are a large number of elements necessary for crop growth. They have a good coordination effect, and can promote each other to be absorbed by crops and promote the absorption of other nutrient elements.
3. Industrial grade potassium nitrate is mainly used for heat conduction molten salt in fine chemical industry and organic chemical industry. It is also used as catalyst and beneficiation agent. Industrial grade potassium nitrate can also be used to manufacture fireworks, black powder, tobacco, chemical reagents, catalysts, ceramic glaze, glass and compound fertilizer. In addition, potassium nitrate is used as auxiliary material in metallurgical industry.
