Q Q: 506615608
With the rapid development of economy, China pays more and more attention to environmental protection, and green development has gradually become the national choice. At the same time, the requirements for environmental protection are improved, which puts forward higher challenges for energy saving of enterprises. As the energy-saving equipment in the manufacturing process of melt blown fabric, how to choose the screw blower is related to the operation cost of the whole melt blown fabric factory. Then why does meltblown cloth always choose oil-free screw blower? Let's analyze the reasons.
First of all, from the compression principle, screw blower belongs to the internal compression volumetric blower. The operating principle of screw blower is that two parallel male and female rotors mesh with each other in the cylinder to form the working volume. Through the synchronous gear, the rotor moves in reverse, and the volume changes periodically to complete the internal compression, and the compressed gas is sent to the muffler for discharge.
Melt blown cloth is the core of mask to resist virus invasion. Through screw extrusion equipment, the particles are made into molten polymer. Compressed air is used to blow the molten polymer extruded from the spinneret hole of the die head to stretch it to form ultra-fine short fiber. The melt blown cloth is formed by self adhesion and condensation on the receiving device.
There are many factors affecting the quality of meltblown cloth. For compressed air, temperature and pressure are the key factors. If something is wrong, it is impossible to produce qualified and safe meltblown cloth products. The outlet temperature of oil-free screw blower is about 130 ° C, which has high heating efficiency and more energy saving.
Permanent magnet variable frequency blower has wider pressure range and better constant pressure effect, which can meet the field application. The most important point is that the screw blower has no water and oil.
Screw blower is water-free, oil-free, low noise, large displacement and other characteristics, which is more suitable for melt blown cloth market. Therefore, reasonable selection of suitable oil-free screw blower model can achieve the expected energy-saving effect and product quality standards.
