High alumina ceramic ball

Inert porcelain ball execution standard

Compressive strength: select the testing machine with enough pressure and high precision to measure the force, and take five porcelain balls as samples. The samples were placed in the center of the press plate of the testing machine, and the samples were loaded evenly and stably with oil absorbent paper of 1 ~ 2mm between the samples and the upper and lower press plates at a speed of 5 ~ 20mm/min or 0.5 ~ 3.5kn /min. The pressure value of the samples at the time of failure was read and the arithmetic mean value was calculated as the test result

Alumina content: alumina ball according to the content of feldspar, feldspar - mullite, mullite, mullite - jade, jade and other different materials. More customers of different design requirements to match, generally high aluminum with industrial alumina, low aluminum generally with chemical porcelain clay as raw material. Alumina balls were determined by GB/ t4734-1996, chemical analysis of ceramic materials and products.

Inert ceramic ball

Inert porcelain ball is widely used in petrochemical industry, environmental protection and natural gas industry, as well as in the reactor to support the role of covering protection catalyst. The wide use of the market makes its economic benefits considerable. According to its aluminum content, inert porcelain ball can be divided into ordinary porcelain ball, aluminum porcelain ball, high aluminum porcelain ball and so on.

An overview of the

The inert porcelain ball has the characteristics of high strength, high chemical stability and thermal stability. The inert porcelain ball can withstand high temperature, high pressure, and acid, alkali, salt and various kinds of baisheng inert porcelain ball

Machine solvent corrosion, inert porcelain ball is widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries. As the supporting and covering material of the catalyst in the reactor, the inert porcelain ball can cushion the impact of the liquid and gas entering the reactor on the catalyst, protect the catalyst, and improve the distribution of liquid and gas in the reactor.
