Inert alumina ceramic balls
Inert alumina ceramic balls are referred to as inert ceramic balls, also known as inert alumina balls. It is processed from high-quality chemical clay raw materials. Inert alumina ceramic balls have the characteristics of high strength, high chemical stability and thermal stability. Inert alumina ceramic balls can withstand high temperature, high pressure and acid, alkali, salt and various Corrosion of organic solvents, inert alumina ceramic balls are widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries. As a support and covering material for the catalyst in the reactor, it can buffer 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.
Inert alumina ceramic ball material: feldspar, feldspar-mullite, mullite, mullite-corundum, corundum.
2. Technical indicators of inert alumina ceramic balls: water absorption ≤5% acid resistance ≥98% alkali resistance ≥80~95% heat resistance temperature ≥1300~1700℃
3. Chemical composition of inert alumina ceramic balls: feldspar containing Al2O3: 20-30%; feldspar-mullite containing Al2O3: 30-45%; mullite containing Al2O3: 45-70%; mullite containing Al2O3: 45-70% Stone-corundum containing Al2O3: 70-90%; corundum containing Al2O3≥90%; Al2O3+SiO2≥90%; Fe2O3≤1%.
4. Implementation Standard of Inert Alumina Porcelain Balls People's Republic of China Chemical Industry Standard HG/T 3683.1 - 2000 "Industrial Porcelain Balls - Inert Porcelain Balls".
5. Inert alumina ceramic ball size: 3mm, 6mm, 8mm, 10mm, 12mm, 13mm, 15mm, 20mm, 25mm, 40mm, 50mm, 60mm.
Introduction to the production process of inert alumina ceramic balls
Formulate the formula according to the requirements of water absorption, aluminum content, strength, etc., and then ball mill;
2. After the filter press and vacuum mechanism, the mud strips for the production of inert ceramic balls are produced (during the period, the moisture must be ensured);
3. Carry out accurate mud strip cutting (the size of the mud strip is equivalent to the specification of the inert ceramic ball to be produced), and select the extrusion forming process to accurately form it;
4. The semi-finished products of the inert ceramic balls are put into the kiln after entering the drying room or naturally dried in the shade;
5. High temperature sintering of semi-finished inert ceramic balls;
6. Screen and package the finished products of inert alumina ceramic balls.
