Ceramic Filter Plate with Silicon Carbide Ceramic Foam - Excellent Thermal Shock Resistance

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: Influence factors of ceramic filter: Ceramic filter board, also known as ceramic filter membrane, ceramic plate, ceramic plate, filter plate, etc., is made of corundum, silicon carbide and other special process made of new filter media. At present, as the core component of the ceramic filter, ceramic filter plate has been widely used in solid-liquid separation of iron concentrate, zinc concentrate, sulfur concentrate, copper concentrate, nickel concentrate, molybdenum concentrate, lead concentrate, tungsten concentrate, manganese ore, vanadium ore, aluminum ore, gold ore, non-metallic mine Ore Concentrate Dewatering and coal, chemical industry, papermaking, pharmaceutical, chemical, food, environmental protection and other industries.

Q: What are the causes of the powder moisture in the ceramic filter?: 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: Why should filter core be used in backwash of ceramic filter?: Ceramic filter recoil stage is with certain pressure of clean water from the inside out washing ceramic filter plate, the outer aperture ceramic filter plate from inside is gradually reduced, such as flushing water and unclean inside contain impurities that may block ceramic filter board, other structures in the recoil stage of pollution. Such as recoil, water is not clean, you must go through the water filter cartridge to filter again, the choice of filter core, the higher the accuracy of filtration, the more clean water, but the filter is more likely to plug, scrap. Of course, the water is clean and contains little solids. The filter core is not easy to plug and even water filters can be removed.

Q: Common troubles of ceramic filter: (1) low vacuum, can not meet the production requirements. The main reason is the vacuum pipeline leakage, vacuum pump circulating water is not enough, vacuum pump impeller wear and tear, distribution head wear, ceramic filter plate damage, filtrate tank drainage valve is not closed, pulp trough material level is lower;(2) low or fluctuating backwash water pressure. The main reason is the blockage or leakage of the backwash water pipe system and the distribution of head wear;(3) the liquid level of the filtrate tank is high. The main reason is that the circulating water pump impeller or pump shell wear, pressure is insufficient, so that the drain valve can not open or drain valve itself failure, and filter barrels and circulating water pipe between the leakage;

Q: Microporous ceramic filter plate cleaning: Ceramic filter comes with a combined cleaning system, usually to ensure backwashing normal, combined cleaning (nitric acid + ultrasonic + backwash) in place.

Q: Does the ceramic factory use hydrochloric acid?: Ceramic filter comes with a combined cleaning system, usually to ensure backwashing normal, combined cleaning (nitric acid + ultrasonic + backwash) in place.

Q: Ceramic filter cleaning, sulfuric acid cleaning: Ceramic filter medium is ceramic, ceramic generally resistant to strong acid, alkali, cleaning, it is best to use nitric acid, hydrochloric acid next, not recommended to use sulfuric acid.

Q: Excuse me, what's the reason that all ceramic filters do not attract ore?: After the joint cleaning, 0~2 hours of suction effect may be good, 2~4 may drop slightly, 4 hours later will become worse and worse, or even suck. This case should first check the backwash water pressure (instantaneous maximum pressure should not be less than 0.08MPa) is to meet the requirements, should also advance down (to ensure normal and ultrasonic cleaning combined with nitric acid dosage sufficient) and prolong the cleaning time.

Q: Beneficiation ceramic filter no problem, the technical parameters are normal, but filter out the concentrate water suddenly excessive, what is the reason?: First, the fineness of the material, resulting in the filter board filter cake moistureTwo, the vacuum can not reach, in the circumstances, whether the vacuum pipe leak

Q: How to determine the quality of ceramic fiber filter board simply?: Ceramic fiber filter board, in fact, ceramic fiber board, also known as aluminum silicate, refractory fiberboard.
