Ceramic substrate 20/40 process bauxite with high content finely and make it into small and round grains with different grain diameters like 0.45mm-0.90mm, 0.09mm-0.224mm with chemical agents and transformation agents. Finally fire them under high temperature. In this way, high strength fracturing propping agent is finished. It has high strength, low breaking rate, good sphericity, etc. Under closing pressure. It is the best product for stratum fracturing transformation of oil and gas field at present.
After coated with catalysts, this product is applied in catalytic converter of diesel vehicle to catalyze, convert and purify the exhaust, making vehicle exhaust reaching standards of Euro IV and Euro V. Technical performance of the product in the leading position in domestic, close to or reach the advanced level of similar foreign product.
Ceramic Substrate Usage
It is mainly used for supporting fissure of stratum fracturing transformation of deep oil and gas field.
Enhance permeability of stratum Circulate oil gas.
Increase output of oil gas.
*Low thermal expansion coefficient
*High porosity of hole on the wall, good liquidity and uniform distribution.
*High temperature resistance, chemical corrosion resistance, thermal shock resistance and thermal shock resistance is strong.
*The pressure drop is small.
*Cold start performance is good, low light-off temperature, high conversion efficiency.
