Products Description
Products introduction:
Porous ceramic balls is also called filtering balls, known as inert alumina open porcelain ball. Its main chemical
composition is aluminum oxide (AL2O3%) and silicon dioxide (SiO2), the main crystalline phases are corundum, corundum - mullite,mullite, mullite - feldspar, quartz and a small amount of glass phase. My company's opening porcelain ball production by using high temperature resistant, high temperature, high thermal shock of a - Al2O3 industrial high alumina, superfine kaolin and plasticity opening of refractory clay as the main raw material to produce ceramic ball, machinery with good strength, high temperature resistant, resistant to temperature 1790 ℃), good thermal shock resistance, excellent corrosion resistance to acid and alkali chemical special, in addition to the hydrogen fluoride, Can withstand all inorganic acid and sodium hydroxide and other strong alkaline substances of the solution.
The open-hole porcelain ball is pressed or manually shaped by a steel die machine with an open-hole device. The appearance of the ball after molding has one or two, three, five, seven or nine holes. Compared with ordinary inert porcelain spheres, the bulk voidage increases by 6-10% and the specific surface area increases by 15-25%. The larger the specific surface area of the open porcelain ball, the higher the contact reaction efficiency. The product has suitable specific surface area and high voidage, which can reduce the bed weight, make the fluid in the purifier and reactor evenly distributed, the mass and heat transfer reaction evenly carried out, and do not make the reactants and heat concentration appear in a large number of local places. The high porosity of the open-hole porcelain ball can absorb and remove the solid particle impurities such as colloid, coke powder and heavy metal in the gas and liquid of various raw materials, and prevent the catalyst poisoning caused by carbon deposition during operation. To protect the catalyst.
The open-hole porcelain ball is suitable for use under high temperature and high pressure in hydrogen production, gas
purification, first and second stage conversion furnace of ammonia synthesis in coal chemical industry, catalytic reforming, hydrogen production, hydrogenation and catalytic cracking of crude oil deep processing as proppant or protective agent.
