Silicon Carbide Ceramic Foam Filter
Silicon Carbide Ceramic Foam filter is justdeveloped as a new type molten metal filter to decrease casting flaw in recentyears. With its characteristics of light-weight, high mechanical strength,large specific surface areas, high porosity, excellent thermal shock resistance,erode resistance, high-performance, siliconcarbide ceramic foam filter is designedfor filtering impurities from molten Iron & Alloy, nodular cast ironcastings, grey iron castings and malleable castings, etc.
CNBM silicon carbide ceramic foamfilter ischaracterized by high porosity and mechanochemical stability and excellentresistance to thermal shock and corrosion from moltenmetal. It can effectively remove inclusions, reducetrapped gas and provide laminar flow when iron molten metalfiltrated, ceramic foam filter is machined to tight dimensionaltolerance during production, this combination of physical properties andprecise tolerance make them first choice for iron molten metal filtration.

- Q: Is the filter plate of the ceramic filter afraid of freezing?
- In addition, the temperature is one of the factors affecting the filter suction effect of ceramic filter. The lower the temperature, the worse the suction effect.Therefore, the ceramic filter plate, especially the ceramic filter plate after use, should be protected under low temperature environment.
- Q: How many degrees does the ceramic filter melt?
- Spinel is basically over 1600-1700. It's not too acid proof.There are other materials such as silicon nitride. Ceramics can be more than 1300 degrees in temperature. So the material you are using now is unlikely to melt and melt, and you can change it into one of the top materials. Baidu, this stuff is all over the street.
- Q: Influence factors of ceramic filter
- (1) the particle size and the distribution of the material match the microporous of the ceramic filter plate. Although the ceramic filter plate aperture is bigger, easy to suck the pulp, but easy to cause the ceramic filter board to block up.(2) the ceramic filter plate with the same ceramic filter plate with high pore permeability and high water permeability is selected with high water permeability and good slurry absorption performance. The spindle speed is slow, the formation time of growth in the area of vacuum filter cake, production capacity increased gradually, but because the unit time of grout thickness and spindle speed slow is proportional to, so the ceramic filter capacity in a range of showing the highest.
- Q: What is the filtration accuracy of 50nm ceramic membrane?
- The filtration accuracy is the maximum particle size that the membrane can pass through.
- Q: What are the materials that make up the ceramic mold?
- At present, the commercialized porous ceramic membranes are mainly composed of 3 types: flat plate, tubular and multi channel. Flat film is mainly used for small-scale industrial production and laboratory research. The tubular membrane is combined with rice to form a heat exchanger similar to a column tube heat exchanger, which can increase the loading capacity of the membrane, but is gradually withdrawn from industrial application due to its strength problem. The size of the applied ceramic membrane usually adopts a multi channel configuration, that is, a plurality of channels are distributed on a circular cross-section, and the number of general channels is 7, 19 and 37. The main business of the inorganic ceramic membrane preparation technology: using solid particle sintering preparation carrier and microfiltration membrane by sol-gel method in the preparation of ultrafiltration membrane: glass membrane by phase separation method: using special technology (such as chemical vapor deposition, electroless plating, etc.) the preparation of microporous membrane or dense membrane. Its basic theory involves colloid and surface chemistry, material chemistry, solid state ion science, material processing and so on.
- Q: What is the reason that ceramic filter does not absorb mineral powder?
- In order to avoid frequent fluctuations in pressure and pressure within a short period of time, a buffer cylinder with a stabilizing effect is provided in the backwash pipe.
- Q: What's the acid of the ceramic filter plate?
- Ceramic filter automatic control system: control system through the metering pump will be concentrated nitric acid automatic mixing ceramic filter plate into nitrate after proportioning through the pipeline, so that it can be dissolved, dredge the blockage in the most microporous ceramic filter plate. This is the ceramic filter plate pickling, pickling, acid dosage should be sufficient as little pickling effect.
- Q: The vacuum of ceramic filter is not enough
- The vacuum degree of ceramic filter is about -0.08MPa, if the ceramic filter is less than 0.06MPa, the vacuum is not enough. If the vacuum of ceramic filter is not enough, it will influence the suction effect of ceramic filter (mainly the thickness of filter cake and water content of filter cake).
- Q: What are the reasons for the program alarm of ceramic filter?
- If you say "lean" is the ceramic filter suction when the ceramic filter plate into a cake of thin, high water content, is the ceramic filter for their own reasons, can from the following aspects: the investigation considering this phenomenon is always so recently or just happened, if you have been so, probably because your selection is not suitable for pulp the ceramic filter (such as mud content, fine grain size, ceramic filter plate selection such as inconsistent or unqualified ceramic filter). If this anomaly has occurred recently, it is possible to change the ore condition, and the operation parameters of ceramic filters or the cleaning are not up to standard. You can check the vacuum system (vacuum generally ranges from -0.09 to -0.075MPa), backwashing system (generally refers to the filtered water recoil 0.07 ~ 0.12MPa), acid (HNO3 system standards), ultrasonic system is normal.
- 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.
