Water electret melt blown cloth special blower-the best choice for water absorption

What is water electret?

The water electret technology originated from 3M in the United States. The difference from the traditional melt blown cloth electret process is: The traditional melt blown cloth uses a corona electret. The surface electret is obvious, but the filtration efficiency cannot reach the peak value and the storage will As time decreases, the static electricity on the surface of the material decays significantly: the water electret melt blown cloth is a high-pressure water pump to deliver the prepared pure water to the water jet device at high pressure, and the blower-shaped nozzle sprays the melt blown cloth, and the two frictions produce Static electricity; the performance of the water column pole melt blown cloth is that the amount of static electricity is saturated, and the water electret charging method can detect the oil and salt properties, which can effectively solve the problem of the improvement of the melt blown cloth electro electret filtration efficiency and the decrease after storage in the mask industry.

Water electret process

1. Melt blown cloth generation: select electret high-fluidity polypropylene and add a small amount of water electret masterbatch.

2. Pure water preparation: select tap water as the water source. The water source is filtered through activated carbon in a gravel tank, reverse osmosis agent and hydrochloric acid are added to the filtered water source, the water source is subjected to secondary filtration with reverse osmosis membrane, and the filtered water source is automatically detected Add alkaline industrial reagents to complete the preparation of pure water.

3. Water electret process: The prepared pure water is delivered to the blower nozzle through the high pressure water pump, and the blower nozzle sprays the melt blown cloth into a spunlace. The water and the melt blown cloth fiber friction generate electric charges to complete the spunlace pole.

4. Exhaust gas treatment: the exhaust gas is sucked out through a complete set of negative pressure blower equipment for water vapor separation

5. Drying process: send the spunlace electret melt-blown cloth into the drying box through the conveyor net, use hot air for drying, and cut and wind after drying.

Why use a multi-stage centrifugal blower

The multi-stage centrifugal blower adopts negative pressure technology to absorb water in the production of water column polar melt blown cloth, which has achieved water vapor separation.

Why use multi-stage centrifugal blowers for many suction equipment on the market?

1. Most of the current meltblown fabric production of water column electrode technology adopts the 1600 type production line, and the flow rate requirements for water vapor separation are relatively high, and other equipment on the market cannot meet the flow rate requirements;

2. Environmental factors. The country has higher and higher requirements for environmental pollution reviews. Multi-stage centrifugal blowers have low noise, low vibration, and unique operating sound frequencies. They have no impact on the surrounding environmental noise, and the pollutant discharge permits meet the national standards;

3. Energy-saving, "Dacheng" multi-stage centrifugal blower adopts foreign advanced technology and integrates domestic first-class industrial manufacturing experience, high efficiency, power reduction by 10-15%, and annual energy saving of up to 20%; economic benefits are very considerable.

4. Convenient installation, "Dacheng" multi-stage centrifugal blower is integrally cast, and the impeller is formed by aluminum alloy gravity casting steel mold, with stable aerodynamic performance and can be fixed without anchor bolts;
