some usages of Melt blown nonwoven fabric
Liquid filter material and battery separator
Polypropylene melt blown fabric is used to filter acid and alkaline liquid, oil, oil and so on. It has been regarded as a good diaphragm material by battery industry at home and abroad. It has been widely used. It not only reduces the cost of battery, simplifies the process, but also greatly reduces the weight and volume of the cell.
Oil absorbing materials and industrial wipes
All kinds of oil absorbing materials made of polypropylene melt blown cloth can absorb 14-15 times of its own weight. It is widely used in environmental protection engineering and oil-water separation engineering. In addition, it can be used as clean material for oil and dust in industrial production. These applications give full play to the characteristics of polypropylene and the adsorption of superfine fibers prepared by melt blowing.
The average diameter of melt blown superfine fiber is between 0.5 and 5 m, the specific surface area is large, and a large number of micro pores are formed in the cloth, and the porosity is high. This kind of structure has a lot of air stored in it, which can effectively prevent heat loss and has excellent thermal insulation property. It is widely used in the production of clothing and various thermal insulation materials.
