Product Description:

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:What is the reason that ceramic filter does not absorb mineral powder?
There may be a failure of the filtrate pump, the diaphragm of the pump is damaged, and the mechanical seal of the pump is invalid
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.
Q:What is the filtration accuracy of 50nm ceramic membrane?
It should be noted that due to wear, plugging and so on, the new and different degrees of ceramic film, the pore size will change. Micron scale ceramic membrane filtration accuracy is very good, nano scale aperture range of such a small ceramic film does not know in what way.
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:The efficiency of ceramic filter is low. What's wrong with it?
Ceramic filter is a new and efficient dehydration equipment. If users find the ceramic filter board surface suction effect is poor, or even do not suck slurry, we should promptly investigate the causes, so as not to affect production efficiency.
Q:What filter material are placed in the aquarium filter?
Submerged in water. Submersible pumps and filter cotton (often replaced by sponge) installed in one, and some brands will also be installed heaters, which become multi-purpose fish farming equipment. When working, the water is absorbed into the filter in many directions, and the filtered water is returned to the water tank by other means. This filter because of its low price and popular beginners of all ages, but the effects from the use of view, only suitable for small fish density, on the flow and filtration requirements are not high, a small aquarium, "fish" will be built in filter (especially the heating function of the filter for seedling and foster) water tank. The effect is very good. The biggest disadvantage of this device is that when it stops working, a lot of dirt stuck to the filter runs back into the water.
Q:What is the working pressure of the ceramic filter?
The backwash pressure is the size of the backwash of the ceramic filter during recoil stage, and the recoil pressure is generally less than 0.12MPa. The greater the pressure, the better the recoil effect, the better the service life and the suction effect of the ceramic filter plate, and the worse the service life and the suction effect of the ceramic filter board. The backwash pressure of the ceramic filter shall be no less than 0.07MPa.
Q:The use of water glass as beneficiation agent, copper concentrate in the ceramic filter can not filter, how to do?
As everyone knows, ceramic filter medium is a ceramic filter plate, microporous ceramic filter plate with a lot of distribution from the outside to the inside capillary effect, its mechanism is based on the capillary effect of microporous ceramic filter, filtration, the filtrate (generally refers to water) through these pores under the action of the vacuum suction pump, filter cake is trapped on the surface of the ceramic filter plate.
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:What are the functions of honeycomb ceramic filters?
At present, it is widely used in metallurgy, foundry industry, metal melt filtration, using mullite (cordierite) ceramic materials
