+8613921611100Roots blower is a positive displacement blower, and its main parameters in the production of meltblown non-woven fabrics are: the air flow (air volume) in the drafting channel of the meltblown equipment and the passive pressure (wind pressure) of the system. In actual operation, the model of the Roots blower should be selected according to different needs, such as the melt index of PP material, the modulus of the spinneret and the number of groups, the running speed of the production line, the width and other parameters to calculate the air volume and air pressure requirements.
According to the successful application practice of Jingong Roots blower on more than 100 meltblown nonwoven equipment, it can be concluded that the power requirements of the Roots blower matched with the meltblown nonwoven production line range from 11kw-90kw, and the actual passive pressure is generally in About 58.8kpa, the air flow requirement of the drafting channel is between 4.0-60m³/min. Meltblown equipment manufacturers can select Roots blowers according to the actual needs of their customized equipment.
The fiber diameter of the melt-blown non-woven fabric material for masks is only about 2 μm, and it is made of high-melt index fiber polypropylene (pp) material. The melt index of the raw material is generally 800-1600g/10min, and the speed of high-speed hot air can pull its fibers. The stretching effect has a great impact. In the production drawing channel process of melt-blown non-woven fabrics, it is very important to choose equipment that can provide high-speed hot air, especially as Roots blower equipment
