Nickel-clad diatomaceous earth is a high-performance thermal spraying material with good adsorption properties and chemical stability, which is widely used in large mechanical turbines, mechanical seals, etc. So, what is the production process of nickel-clad diatomaceous earth? This article will introduce it to you in detail. 
1. Preparation of raw materials.
The main raw materials of nickel-clad diatomaceous earth are diatomaceous earth and nickel salts. Diatomaceous earth is a natural inorganic non-metallic material with good adsorption properties and chemical stability, and is an important raw material for the preparation of nickel-clad diatomaceous earth. Nickel salt is the key raw material for the preparation of nickel-clad diatomaceous earth, and the commonly used ones are nickel nitrate, nickel chloride, etc.
2. Preparation of nickel-clad diatomaceous earth.
1.Diatomaceous earth treatment.
First, diatomaceous earth is treated to remove impurities and organic matter to improve its adsorption performance and chemical stability. Treatment methods include water washing, pickling, alkali washing, etc.
2.Nickel salt impregnation.
The treated diatomaceous earth is mixed with nickel salts and allowed to be fully impregnated. There are two methods of impregnation: dry impregnation and wet impregnation, of which wet impregnation is a commonly used method.
3.Drying.
The impregnated diatomaceous earth is dried to evaporate its water to form a complex of nickel salt and diatomaceous earth.
4.Restore.
The dried composite is reduced to nickel metal to form nickel-clad diatomaceous earth.
3. Product performance test.
The prepared nickel-clad diatomaceous earth needs to be tested for performance to ensure its adsorption performance and chemical stability. Commonly used test methods include specific surface area test, pore size distribution test, adsorption performance test, etc.
Fourth, product packaging and storage.
The prepared nickel-clad diatomaceous earth needs to be packaged and stored to ensure its quality and stability. Commonly used packaging methods include plastic bags, cartons, etc., and the storage conditions are dry, moisture-proof, light-proof, and shock-proof.
Summary: The production process of nickel-clad diatomaceous earth includes raw material preparation, preparation, performance testing, and product packaging and storage. Among them, the preparation process is the key, and the steps of impregnation, drying and reduction need to be mastered to ensure the quality and performance of the product. At the same time, product performance testing and packaging and storage are also links that cannot be ignored and need to be strictly controlled.
