product presentation
The full name of the pore-opening porcelain ball is inert alumina pore-opening porcelain ball. It is formed on the basis of the original inert porcelain ball by the steel mould machine with the pore-opening device or by hand. The formed ball has one or two, three, five or seven straight circular holes.Opening of our company product USES the high temperature resistant ceramic ball a - Al2O3 industrial high purity alumina, superfine kaolin and plasticity refractory clay as the main raw material through special punching mould opening porcelain ball, with good mechanical strength, resistance to high temperature (1790 ℃ maximum temperature resistance), good thermal shock resistance, excellent corrosion resistance to acid and alkali chemical special, except HF acid, all of the inorganic acid and organic acid and strong alkali material such as sodium hydroxide solution.
Compared with the ordinary inert porcelain balls, the bulk voids and specific surface area of the ceramic balls are increased by 6-10% and 15-25% respectively.The larger the specific surface area is, the more efficient the contact reaction is.Products for appropriate specific surface area and high void fraction, can reduce the bed weight, make the purifier, fluid distribution in the reactor, heat transfer and mass transfer reaction uniform, efficient, don't make the reactants and heat concentration, massively appeared in the local place. Opening porcelain ball higher porosity, can accommodate adsorption removal of various materials in gas liquid solid particles such as colloid, coke powder and heavy metal impurities, prevent operation process caused by carbon deposit catalyst poisoning. The purpose of protecting catalyst. At the same time opening porcelain ball reaction tower in use with low pressure drop, reduce the tower resistance, improve the efficiency of mass transfer of the whole of the reaction tower,It plays an important role in increasing output and improving product quality.
