Specifications


Alumina circle ceramic foam filter 

1.Even aperture, high porosity, proper sinter 

2.Metal mesh to prevent secondary pollution


Alumina circle ceramic foam filter

The product, adopted good portiforium foam and high purity ceramic , effectively removes non-metal solid mixture from aluminium and aluminium alloy fusant.

Advantages:

even aperture, high porosity, proper sinter, high strength of anti-flexing and anti-compression, effective filtering.

It is widely applied to the aluminium fusant filter equipment of continuous casting, half-continuous casting, gravity casting, and low pressure casting.

Ceramic foam filters are different from aperture specifications from 10 to 45ppi, with different sizes and shapes.

Besides the general specification ,we can offer the product according to the customers requirements.

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:Working principle, ultrasonic trouble and troubleshooting of ceramic filter
It is based on the action principle of capillary pore and realizes the solid-liquid separation through the capillary action principle of the micropore. Specifically, is the use of microporous ceramic plate water impermeable properties, extraction of ceramic plate and external cavity vacuum pressure, the suspended material groove under the action of the negative pressure adsorption on the ceramic plate, solid material through the porous ceramic plate can not be trapped in a ceramic plate surface, and the liquid due to the hydrophilic effect of vacuum pressure difference and ceramic plate by entering the gas-liquid distribution device, and then discharged or recycled, so as to achieve the purpose of solid-liquid separation.
Q:Ceramic filter capacity.
60 square meters of ceramic filter power 35kW or so, a high degree of automation, each class can complete the operation.
Q:How much is the accuracy of 50nm ceramic membrane filtration?
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:Common troubles of ceramic filter
The metering pump is not working properly and backwash water into the bucket of acid. The main reason is that the metering pump is not switched on, the diaphragm is worn out, the frequency is too low, and the check valve of the acid pipe and backwash pipe is worn out.
Q:Ceramic filter in vacuum pressure enough, the ceramic plate does not suck pulp, what is the reason for analysis?
The incoming mud content, fine particle size, pulp itself is not suitable for the use of ceramic filter dehydration, if the use of ceramic filter dehydration in this case, will accelerate the blockage of ceramic filter plate, blocking the situation after the second reference description.
Q:Does the ceramic factory use hydrochloric acid?
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. (do not recommend sulphuric acid)
Q:What are the functions of honeycomb ceramic filters?
High quality and high density straight hole mesh, the product has high heat resistance and impact resistance properties of cast high fever temperature, design straight hole to guarantee the balance between strength and flow, effectively remove impurities and slag particles, the mechanical properties of casting, the surface quality and the qualified rate of products is greatly improved.
Q:Is the filter plate of the ceramic filter afraid of freezing?
The ceramic filter plate by table and the distribution of a large number of porous capillary ceramic filter, when working in the water slurry channel is used so the microporous ceramic filter plate internal residual has a lot of water, such as low temperature, the inside of the frozen water volume will swell, causing damage to the ceramic the inside of the microporous filter plate structure.
Q:Can the plate filter press pass through the filter plate?
There are many types of pumps to be used, such as screw pumps, slag pumps, rotary pumps, piston pumps, and diaphragm pumps.
