How to produce melt-blown cloth that meet the standards? The melt-blown cloth does not look special, but the production process is very complicated. Its production process can be summarized into three major links: first, naphtha is extracted from petroleum, then chemically processed into polypropylene, and finally melt-blown. Here mainly introduces the last link. Both selection of raw materials and production process are important.
Polypropylene is easy to form filaments, and when the melt flow index is high (MFI≥1500g /10min), it can become quite fine fibers (diameter 2 ~ 3μm). Although the gap of the melt-blown cloth produced is much larger than the size of the new (about 0.1 μm), its ability to filter viruses in the environment is still very strong.
Because the virus cannot exist independently, its transmission route mainly includes secretions and droplets when sneezing, the size of the droplets is about 5μm; Melt-blown cloth is essentially a fiber filter. When the droplets containing the virus are close to the melt-blown cloth, they will also be electrostatically adsorbed on the surface and cannot penetrate.
(1) Sanitation and environmental protection, constant temperature and humidity
(2) 1.6m SS specification, the required size of the factory building: 36m long * 15m wide * 12m high
(3) The total installed power capacity of the production line is about 500KVA, practically about 180-200KVA.
(4) The circulating cooling water consumption of this production line is not large, the circulating volume is 50 cubic meters/hour (0.25~0.35MPA at 20°C), and the required water supplement capacity is 1 cubic meter/hour
Main Technical Parameters
Jwell JWS150/30 extruder uses pp as raw material, with an extrusion capacity of 350kg/h and a center height of 650mmDue to the optimized screw and new barrel design, the extruder has the following advantages: high plasticization rate, uniform melt, continuous and stable production. The high-performance gearbox reducer adopts advanced transmission technology with large torque, long life and low noise. The netting machine is self-made by our company. The transmission motor AC motor, the transmission rod needs to be covered with rubber, and the transmission is connected by universal joints, which has good stability, fault alarm system, correction device, infrared induction type, alarm X1, correction X1Double-station rewinding, rewinding, cutting, and pneumatic are integrated to achieve the purpose of automatic rewinding.Tensile force control is to meet different product specifications, different requirements for required tension, and linear speed requirements of coiling in the hot rolling mill, the rolling speed of the AC variable frequency speed control motor is controlled through the tension sensor and electronic control to achieve constant growth. Forceful.Provide gas valves, instruments and pipe fittings and electronic components directly connected to the equipment.
