Porous Sintered PE Filter for water,oil, air and dust filtration

Sintered PE Filter can be used for vacuum filtration, pressure filtration or gravity filtration. in order to use this product well, the following points must be mastered:

1. Correct selection of filtration parameters (optimum filtration pressure difference, filtration speed and filtration area, etc.), therefore, a small test to determine the design parameters must be carried out in advance.

2. According to the requirements for filtration in production and the characteristics of porous PE media, the mechanical structure of the filter should be correctly designed.

3. There must be certain operating procedures during use, especially at least 5-10 minutes of low-pressure 0.3-0.5kg/m2 filtration at the start-up stage. lt is forbidden to reach the normal operating pressure as soon as it is started otherwise the capillary pores will be blocked too quickly, which will significantly reduce productivity,

4. The porous PE filter should be equipped with a certain volume of air bags (one air bag can be used for several filters) for back blowing slag removal and back blowing regeneration. The back blowing pipeline should be thicker and the back blowing valve Ball valves or cocks should be used, the blow back speed should be fast, and the blowing time should not be long, generally no more than 1 second, otherwise the compressed air will be wasted.

5. According to the characteristics of different materials, different regeneration operation procedures should be formulated.

1. Raw material preparation: select HDPE granules, mix and granulate (hydrophilic modifier or conductive material can be added).

2. Sintering and molding: Sintering at high temperature (200-300℃) under high pressure to form a uniform porous structure.

3. Processing and cutting: cut into cartridge sizes as required, end caps are ultrasonically welded or glued for sealing.

4. Cleaning and testing: Remove residual particles, conduct bubble point test, flow test and integrity test.

5. Packaging and sterilization: medical grade products need to be sterilized by gamma rays, regular products are vacuum packed.

1. Material properties: PE with UHMWPE as the main medium has the characteristics of non-toxic, tasteless, no foreign matter dissolution, and biochemical safety.

2. Chemical properties: PE filter media has excellent corrosion resistance, and can withstand various non-strong oxidizing acids, Alkali resistance, aldehyde resistance, aliphatic hydrocarbon resistance, radioactive radiation resistance, etc., excellent chemical properties, and good resistance to organic solvents. Below 80°C it can resist ester ketone, ether and other organic solvents;

3. Temperature resistance: the highest Saturated steam temperature can reach 130*C, long-term continuous use does not exceed 80°C:

4. Mechanical properties: good toughness and strength, impact resistance, not easy to damage,

5. Filtration performance: Filtration accuracy range (0.2-200 microns), high filtration efficiency, controlling the initial pressure can effectively remove solid particles above 0.2 microns

6. Physical properties: The specific gravity of the medium is light, and the theoretical specific gravity is around0.5-0.7g/ml ;

7. Regeneration performance: The capillary pores of PE media have the elasticity of microscopic expansion, and can be efficiently reversed and regenerated by water pressure, air pressure or water-air pressure. Ensure that it can use the acid solution of appropriate concentration to chemically dissolve and regenerate the blockage, so that the filtration performance of the medium can be restored to the original state, and the service life of the quality can be improved;

8. Processing performance: Secondary processing can be carried out by turning, milling, planing, ironing, hot melt-welding.bonding.etc.:

9. Basic characteristics: lt is manufactured y a special sintering process, in which plastic particles are heated to its surface until soft, and melts on the contact surface while approximately retaining its original shape. The resulting shaped body has open continuous pores, the size and number of which depend on the sintering conditions and the size selection of the polymer particles.

1. Large flow: high porosity (around 50%) ensures greater fluid flow per unit area;

2. 2Smooth surface: smooth surface, impurities are not easy to stick, back washing is easy and thorough, and can be reused:

3. Strong anti-fouling ability: high filtration accuracy makes it difficult for impurities to remain in the filter body, and can press the sludge to a water content of 70%;

4. Excellent cost performance: the filter element has excellent comprehensive performance and high cost performance, and is suitable for water treatment, environmental protection sewage treatment, reclaimed water reuse.chemical product filtration and other working conditions with large flow;

5. Resistance to strong acid and strong alkali corrosion, Resistance to various high temperature and strong corrosive chemical raw materials filtration, and resistance to dissolution of organic solvents;

6. Excellent strength and wear resistance ensure its service life;

7. The surface of outer light makes it difficult for impurities to stick together,

8.Good toughness, the filter element is not easy to break;

9. No threshing phenomenon;

10.Strong pressure resistance.

Sinter pe filter can be used as a filter medium for heterogeneous phase separation(solid-liquid,gas-solid, gas-liquid, liquid-liquid) in a physical sense.1.Used for solid-liquid separation: the application of clarification filtration or filter plate filtration, the filtration efficiency of solid particles above 0.2 microns can reach more than 99.7%.

(1) Application in the field of pharmaceuticals and food: such as the filtration of liquid medicine for injections in the production of injections in the pharmaceutical industry and the filtration of bottled water for washing injections,Separation and filtration of tetracycline production; fine filtration of corn oil, soybean oil, rapeseed oil and other edible oils.

(2) Application in the field of environmental protection water treatment: such as the purification and filtration of heavy metal salts in electroplating solutions and industrial heavy metal wastewater in the electroplating industry.and the wastewater containing cadmium, copper, chromium, nickel. lead, etc. is chemically treated and then filtered through PE micro porous tubes. Emission, filtration and recycling of coal-containing wastewater, flue gas water liquid depressurization filtration, dry dust recovery, purification and filtration of electrolysis water;

(3) Application in chemical industry: precision filtration of liquid products, liquid raw materials and liquid intermediates in chemical production, such as precision filtration of various acids, alkalies, salts and most organic solvents acid and sulfur filtration in chemical fiber production , brine filtration in the production of chloral-alkali industry, activated carbon filtration in glyphosate production, filtration of barium sulfate and potassium hydroxide in metallurgical plants, photosensitive film production, and can also be used as plate and frame filter press, after centrifuge and other precision filter.

(4) Application in the field of non-ferrous metals: such as nickel chloride, cobalt chloride, nickel oxalate, cobalt carbonate, nickel carbonate and other non-ferrous metals during the preparation of non-ferrous metals, such as decalcification and iron filtration of pickling solution, and filtration and washing of crystallization solution.

Sintered PE cartridges can be customized in hydrophobic (gas filtration) or hydrophilic (liquid filtration) versions with different interfaces (e.g. NPT thread, flat port). For high temperature or high pressure scenarios, a reinforced construction design is recommended. For further technical specifications or sample testing, please contact us for support.
