Meltblown cloth electromotive electrode production process flow. Qingdao Yihe Non-woven Co., Ltd. "a polypropylene melt-blown non-woven fabric preparation method and its polar equipment" briefly describes the process of the polar water:


Meltblown cloth electroelectret step, meltblown production; polypropylene particles are selected as raw materials, the raw materials of polypropylene particles are transported to the extruder, and the raw materials extruded by the extruder are sprayed through the contact spinneret, the air compressor The airflow generated is the same as the spraying direction of the raw materials, the airflow generated by the air heater is heated, the receiving roller receives the raw materials sprayed by the contact spinneret, and the receiving roller receives the non-woven fabric.


Meltblown cloth electrostation two steps, pure water preparation; water source selection of tap water, water source through the sand tank, activated carbon tank filtration. A reverse osmosis agent and hydrochloric acid were added to the filtered water source, and the water source was subjected to secondary filtration through a reverse osmosis membrane. The filtered water source is added with an alkaline industrial reagent to complete the preparation of pure water.


Meltblown cloth electroelectret three steps, electret process; the prepared pure water is transported to the fan-shaped nozzle through the high-pressure water pump, and the fan-shaped nozzle spunlaces the meltblown cloth; through the friction between the pure water and the non-woven fabric, electric charge is generated to complete Spunlaced electret.


The electric standing electrode of the meltblown cloth has four steps, the drying process; the electric standing electrode of the meltblown cloth is transported to the drying room through the conveying mechanism, and dried by electric heating and hot air spraying; after drying, it is received by the receiving roller.


The patented CNA specifies the process parameters of melt blowing extruder and water electret equipment: the extruder temperature is adjusted to 180 ℃ in one stage, 230 ℃ in two stages, 240 ℃ in three stages, 240 ℃ in four stages and 240 ℃ in five stages; Adjust the temperature of the die spinneret to 238 ℃; The air temperature of the heater is adjusted to 245 ℃; The extruder speed is 7hz; the air compressor speed is 22Hz.


Adjust the pH of industrial reagents to 5-6; reverse osmosis membrane filtration: the water quality after filtration by the primary reverse osmosis membrane reaches a conductivity of 40-45um/s, and the water quality after filtration by the secondary reverse osmosis membrane reaches a conductivity of 4-5um/s; Adjust the water pressure of the high-pressure water pump to 2MPa; the drying room temperature is set at 70-90 ℃; the moisture content of the non-woven fabric after drying is less than 0.02.


Technological innovation promotes the development of the industry. Since the beginning of this year, the manufacturing technology of meltblown cloth electric standing-meltblown cloth industry has been continuously updated and the technology has been continuously innovated. From the selection of meltblown materials (peroxide degradation method, hydrogen conditioning method, metallocene method) to the selection of electret masterbatch (tourmaline method, gas silicon method, organic polymer method), to the selection of electret equipment (molybdenum wire electrostatic rod, needle electrostatic rod, water electret method), the production of meltblown cloth is also ever-changing.
