30 ppi CFF material filtration and purification mechanism<\/strong><\/p>\n

1. Mechanical screening through inertial collision interception and diffusion interception, friction, sedimentation, etc. The filtration efficiency is proportional to the pore size of the foam ceramic mesh. The smaller the mesh, the stronger the ability to intercept small particles.<\/p>\n

2. The deposition layer or filter cake layer effect, with the deposition of particles in the melt and the intersecting and uneven grid support walls of the melt, the ability to capture the heterogeneous particles has improved.<\/p>\n

3. The rough surface formed by the gaps on the surface of the mesh support body increases the interface between the aluminum liquid flow and the ceramic solid surface, which can promote the particle flow direction in the aluminum liquid flow to be more disordered, which is conducive to the capture and deposition of solid particles .<\/p>\n

4. Due to the micro-cracks and pinholes on the surface of the mesh support body, fluoride with strong affinity for particles such as Al2O3 is pre-deposited, which promotes the complete filter layer effect and strong chemical adsorption, and the ability to capture the remaining heterogeneous particles is more Strong.<\/p>\n

Furthermore, the temperature field effect of the melting process and the transmission process of the metal melt structure will inevitably form a thick bottom difference of the alloy solute. The metal melt is redistribution — integration — redistribution — integration, which is also a Very good alloying process, some high-melting metal phases and compounds re-aggregate and grow, and the fine heterogeneous phases grow and conduce to filtration and capture.
\nThis can also be explained from the changes in the concentration of H, Al2O3, Fe phase, and Ti phase before and after filtration. Especially two-stage filtration or pore gradient thick plate filtration is more obvious.<\/p>\n

\"30<\/p>\n

Research and development of low-cost, easy-to-operate ultra-fine pore size, high-strength ceramic foam filter plates that do not drop ceramic particles, and researched the patented technology of dual-stage filtration of deep filter residue. \u0645\u0631\u0634\u062d \u062e\u0632\u0641\u064a \u0644\u0644\u0645\u0633\u0627\u0628\u0643<\/a> is the best choice for high-quality aluminum materials. It is a good measure to solve the problem of pinholes, burrs and black spots.<\/p>\n
