What is inert ceramic ball? What does it do? What is it used for?

Inert ceramic balls, also known as inert porcelain balls, inert alumina porcelain balls, the main chemical components are Al₂O₃, SiO₂, containing a small amount of alkali metal compounds CaO, MgO, K₂O, Na₂O ₃ and a very small amount of Fe₂O₃

Application field and function

Petrochemical industry: As the supporting and covering material of the catalyst in the reactor, it can buffer the impact of the liquid and gas into the reactor on the catalyst, protect the catalyst, and improve the distribution of the liquid and gas in the reactor, reduce the direct contact between the catalyst and the fluid, reduce the wear and deactivation rate of the catalyst, and extend the service life of the catalyst.

Environmental protection field: In the wastewater treatment, it can be used as an adsorbent or reaction medium, with its own porous structure and surface characteristics, adsorption and retention of heavy metal ions, organic pollutants and other harmful substances, so that the purified water can meet the discharge standards; In flue gas desulfurization systems, it participates in chemical reactions to help absorbers capture sulfur dioxide in the flue gas, reducing the risk of acid rain formation.

Natural gas industry: In the natural gas purification device, protect desulfurization, decarbonization and other catalysts, avoid the impact of air flow caused by catalyst powder, to ensure that impurities in natural gas are effectively removed, improve the purity of gas; Laying inert ceramic balls at the bottom of the storage tank can not only prevent the accumulation of water and impurities at the bottom of the storage equipment from eroding the tank, but also optimize the gas distribution in the tank and ensure the stability of natural gas during storage.

Preparation process:

After careful batching, ball grinding, screening, iron removal, vacuum mud, porcelain ball molding, porcelain ball drying, high temperature sintering.

peculiarity

Strong chemical stability: acid, alkali, salt and other chemical substances have a strong resistance, in addition to hydrofluoric acid, can resist all inorganic acids and organic acids and various organic solvents, acid gas, neutral gas corrosion, in a strong corrosive environment can maintain the original performance.

Excellent thermal stability: it can withstand high temperatures of up to thousands of degrees Celsius, and under rapid temperature changes, it is not easy to crack, deformation and other problems, and can be used for a long time in the temperature range of 50 ° C 1300 ° C.

Good mechanical properties: with high strength, high hardness and excellent wear resistance, high compressive strength, not easy to wear, can withstand the erosion of high pressure and high-speed fluid, long-term use is not easy to damage or deformation, can effectively extend the service life of the equipment.

Other features: The surface of the product is smooth after firing, the porcelain is dense, and there is no sandwich and delamination inside; Low water absorption, generally ≤3%, not easy to be penetrated by water; The voidage is 40%48%, with a high and uniform voidage and a large specific surface area.
