Inert alumina ceramic ball

1. Product Overview inert alumina ceramic ball is widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries, as covering and supporting materials within the reactor tower packing and catalyst. It has a high temperature high pressure, low water absorption, chemical stability characteristics. Can withstand acid, alkali and other corrosive organic solvents and can withstand the production process the temperature change. Its main role is to increase the gas or liquid distribution points, support and protect the strength is not high activity catalyst. I developed the product in 88 years is eligible for Outstanding New Product Award and the Science and Technology Progress Award, the same year topped the national list of outstanding new products Huang, 90, won the national scientific and technological achievements certificates, for several years, has been eligible for Sinopec recommended product certification. Products on the market, all users and even students can reflect the effect can be comparable with imported products, some technical indicators even higher than similar foreign products. Inert alumina ceramic www.pxsbaixing.com/25.html 2, material: feldspar, feldspar - mullite, mullite, mullite - corundum, corundum 3, the chemical composition: Long stone containing Al2O3: 20-30%; feldspar - mullite containing Al2O3: 30-45%; mullite containing Al2O3: 45-70%; mullite - corundum containing Al2O3: 70-90 %; corundum containing Al2O3 ≥90% Al2O3 + SiO2≥90%; Fe2O3≤1% inert ceramic balls with high strength, high chemical stability and thermal stability properties, it can be a high temperature, high pressure and acid, alkali, salt and various organic solvents corrosion, widely used in petroleum, chemical, fertilizer, natural gas and environmental protection industries. As the reactor catalyst support and covering material, the reactor can be buffered into the catalyst liquid and gas impact, protecting the catalyst in the reactor and improve the distribution of liquid and gas.
