APPLICATION:For the filtration of molten aluminum and non ferrous alloy.

Alumina Ceramic Foam Filters mainly for filtration of aluminum and alloys in foundries and cast houses .With the excellent
resistance to attack and corrosion from molten aluminum, the filter can effectively remove inclusions, reduce trapped gas
and provide laminar flow and then the filtered metal is significantly cleaner.Cleaner metal results in higher-quality castings,
less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.

-Reduce scrap related to inclusions.

-Reduce costs related to inclusion defects.

-Increase productivity with higher extrusion or rolling speeds.

-Increase casting flexibility with easy alloy changes.

-No holding metal.

Q: What filter material are placed in the aquarium filter?: Generally let off the filter cotton and ceramic rings, there are biochemical balls, coral bone, stone, activated carbon and so onConditional: filter cotton, ceramic ring, biochemical ball, coral bone, stone, activated carbon

Q: What are the poor filtration effects of vacuum disc filters?: Under normal circumstances, high vacuum, vacuum suction, high production capacity, filter cake moisture control is good. At present, some ceramic filters are equipped with two or multi-stage vacuum system to obtain almost absolute vacuum, and can reach 0.09 ~ 0.098MPa.

Q: Ceramic filter in vacuum pressure enough, the ceramic plate does not suck pulp, what is the reason for analysis?: The spindle speed is too fast.The speed is too high to absorb the filter cake.There are other possible reasons.

Q: What is the filtration accuracy of 50nm ceramic membrane?: 50nm refers to the nominal pore size, but it does not mean that the holes in the ceramic membrane are 50nm, but the approximate number of holes. The size of the pores may be between 40~60 and 45 to 55nm. Generally introduced, annotated range, you can also own to detect.

Q: What are the materials that make up the ceramic mold?: From the development trend of rice, the development of ceramic membrane preparation technology mainly in the following 2 aspects: one is the porous membrane research, to further improve the already commercialized inorganic ultrafiltration and microfiltration membrane, nanofiltration membrane with molecular sieve, the development function of gas separation membrane and pervaporation membrane: two in dense membrane research solid electrolyte membrane, ultra-thin metal and its alloy film and ion conduction ability is research hotspot. The commercial porous membranes are mainly ultrafiltration and microfiltration membranes, and their preparation methods are mainly particle sintering and sol-gel. The former is mainly used for making microporous filter membranes, and commercial A1203 films are prepared by particle sintering method.

Q: Why does not the iron filter of the ceramic filter work?: The main speed of the ceramic filter is too fast.The vacuum of ceramic filter is not enough.The cleaning of ceramic filter has not met the requirement.The ceramic filter plate has a near life and a serious blockage.The selection of ceramic filter plate is different.Too much residual of ceramic scraper after discharge.

Q: Ceramic filter ceramic plate blockage, productivity reduction, how to clean, to achieve the best effect cleaning problems: Oxalic acid immersion:For the use of a long time, the method 1, the effect is still no significant improvement, that is how to plug the ceramic filter plate regeneration? The ceramic filter plate with uneven or non sucking slurry can be removed, and oxalic acid or other acid liquid with certain concentration and certain temperature can be taken together to dredge the microporous of the ceramic filter plate.

Q: Ceramic filter suddenly do not smoke, a little later on their own good, what reason?: The size of ceramic filter is generally on both sides of the vacuum tank, such as 50 square meters with 5 square meters of ceramic filter / ring ceramic filter plate combination (possible), there are 10 discs, the ceramic plate left a vacuum tank on the left of the 5 disc for filtration, vacuum filtration tank for the ceramic plate on the right right of the 5 disc. If a vacuum system temporarily fails, it may cause poor suction, no suction, and a normal operation at the other end.

Q: Beneficiation ceramic filter no problem, the technical parameters are normal, but filter out the concentrate water suddenly excessive, what is the reason?: Beneficiation of ceramic filter, the technical parameters are normal, but the water will fill in groove is what reason

Q: What about the leakage of the ceramic filter static and dynamic sealing points?: When the main shaft is rotated, the filter cake is adsorbed on the surface of the ceramic filter plate and dehydrated by the vacuum generated by the vacuum pump.
