Pure water making
Use the tap water directly ,filter by dinas tank and activated carbon first. Then reverse osmosis then put into reverse osmosis and hydrochloric acid, filter the water again use the reverse osmosis membrance.. putting alkaline reagent to the water ,
Water eletret
Through the high pressure water pump, transfer the pure water into sector nozzle, the water go through the nozzle into the meltblown fabric. by friction between water and meltblown to finish the water eletret job
Dry
Delivery the meltblown fabric go into the drying room by belt, using hot air to dry the meltblown fabric. after dry, roller the meltblown fabric.
