A. Ceramic ultrafiltration membrane product
Ceramic ultrafiltration plate membrane can effectively remove organic matter, suspended matter, toxic and harmful substances (such as radium, arsenic), microorganism, algae and oil in liquid, and is the core and key component of new efficient separation technology.It is a kind of ultra-fine filter membrane with asymmetric structure, which is prepared by sintering process with inorganic materials such as alumina. Compared with the traditional organic membrane, it has the advantages of good chemical stability, good reliability, long service life, small occupation space, excellent pollution resistance and low energy consumption, which represents a development trend of water treatment membrane materials.
The service life of ceramic flat film is 3~5 times longer than that of polymer film, the membrane flux is 3~10 times higher, the consumption of chemical agent is reduced by 50 times, the cost of operation and maintenance and energy consumption are reduced by more than 50%. the contamination, chemical cleaning and oxidation of polymer ultrafiltration membranes are an inevitable conundrum, while ceramic membranes are easier to clean, more resistant to contamination, and there is no risk of oxidation.
Our company overcome difficulties, based on German EAC-Elektro company alumina ceramic membrane extruder technology of double-stage vacuum exhaustspiral ceramic ultrafiltration membrane extruder model VAHRS 120B, to meet the needs of domestic users. Not only we use better cost-effective manufacturing materials that our extruder could be cheaper, but also we have further developed the technology of ceramic extruder, such as we fully localized extruder optimizes the structural design of the replacement module and facilitates the maintenance of the extruder and the vacuum chamber structure design is optimi zed to eliminate the defects such as possible leakage pressure due to deformation. Therefore, the extruderis superior to imported extruder in some performance.

D. Configuration and characteristics of COEX-120/120 Double-stage vacuum exhaust spiral ceramic plate(Pipe) extruder:
We make the COEX-120/120 Ceramic plate (tube) extruder, the first pursuit of configuration is the stability and reliability when the extruder in process. The second goal is to give full play to the advantages of our first brand of extruder heart parts in China, we use the PM-HIP stainless steel imported from Europe to get a high corrosion resistance and high wear resistance feature, to get a longer service life of extruder. Modular design is used in the designing of core components to facilitate the replacement of easily damaged parts and reduce the maintenance cost of extruder.
According to the above ideas, our COEX-120/120 ceramic extruder configuration as follows:
*Note: Above double-stage vacuum exhaust spiral ceramic extruder is not equipped with mold die.
