How much aluminum dihydrogen phosphate should I add when producing a foam ceramic filter?

With the development of science and technology, more and more is also high to the requirement of aluminum and its alloy material, and traditional refining degassing process, cannot remove solution small and slurry of non-metallic inclusions in aluminum, so many people studied purification method, according to the mechanism and form of different, can be divided into the adsorption purification, physical purification and filtration purification. Filtration and purification is to make the metal liquid flow through a certain medium, which, according to a certain mechanism, captures the inclusion and thus purifies the metal. In 1978, the United States developed a new filter -- foam ceramic filter, which provides a kind of high-efficiency filter for the production of cast aluminum. It is widely used in the production of semi-continuous ingots and moulded castings.

Aluminum dihydrogen phosphate is used as a binder in the production of ceramic foam filters
Without the addition of aluminum dihydrogen phosphate, the strength of the product is very low, but the amount of aluminum dihydrogen phosphate added is not the more the better, and the excessive addition has little impact on the strength. The dosage should be 2%.
