AI Technical Summary
Existing ceramic membrane supports have high raw material costs, high sintering temperatures, low bonding strength between the support and the membrane layer, and low strength when the porosity is high. In addition, impurities are easily left inside the support, which affects filtration efficiency and service life.
A ceramic membrane support was prepared using perlite aggregate. By designing a connecting layer and a liquid-permeable layer, small-particle perlite was used as the raw material. The connection layer and liquid-permeable layer of perlite were combined to achieve high bonding strength and high porosity between the support and the membrane. At the same time, the pore size and porosity were controlled to reduce the cost of raw materials.
This method achieves high bonding strength between the ceramic membrane support and the membrane layer, improves the strength and liquid flow rate of the support, reduces impurity residue, extends service life, and lowers preparation costs.
