How Is Potassium Cryolite Prepared?
How is potassium cryolite prepared? Today we are going to learn about it.
Potassium cryolite is prepared by the preparation process of mixed grinding method and synthesis method, and can also be produced as a by-product in the production of some products.
Mixing method: The method is to mix and grind KF, AlF3, K3AlF4 and other basic raw materials according to the specified proportion of ingredients. However, the mixed research and development of the preparation of potassium crurite has some disadvantages: the price of some basic raw materials is high and not easy to prepare, and the prepared products sometimes contain free KF, which is easy to dissolve in water, absorb water, and then cause corrosion of weldparts.
Although these shortcomings can be avoided if the melt research method is used, the operation of the melt research and development is more complicated, the energy consumption is high, and the high temperature melting and grinding are required.
Synthesis method: The method avoids the shortcomings of the above methods, the synthesis method uses Al(OH)3, HF, KCl, KOH, K2CO3, KBr and other raw materials to form a commercial preparation process.
The advantage of the synthesis method is that it does not require high temperature melting or grinding, the production process is simple and easy to operate, and the produced potassium cryolite has good quality, low cost and can be mass-produced. It is widely used in automobile aluminum parts brazing industry.
Application of potassium cryolite
Potassium crolyte is used in many industries, but the most widely used is aluminum and aluminum alloy brazing, potassium crolyte flux, is an indispensable important material for connecting aluminum parts.
As a brazing agent, the application of potassium crorite includes: aluminum workpiece brazing joint brazing agent, application in Nocolok brazing process, copper alloy and stainless steel brazing agent, Nocolok brazing wire and improvement.
In addition, potassium cryolite is the main auxiliary material of grinding wheel. Compared with cryolite, potassium cryolite has more obvious advantages, such as reducing the dust of resin grinding wheel in the grinding and cutting process, enhancing the grinding rate of the grinding wheel, and improving the working speed of the grinding wheel. If the disadvantage is that the price is more expensive than conventional cryolite.
In addition, potassium cryolite also plays an important role in the field of steel smelting, glass and ceramics. More potassium cryolite related questions please contact us.
