Common application fields of melt blown non-woven fabric: 1. Application in the field of air purification: for air purifier, as an efficient air filter element and for coarse and medium efficiency air filtration with large flow rate. The utility model has the advantages of small resistance, high strength, excellent acid and alkali resistance, corrosion resistance, stable efficiency, long service life, low price, etc.
2. Application in the field of medical and health care: the dust-proof mouth made of melt spray cloth has small respiratory resistance, is not stuffy, and the dust-proof efficiency is up to 99%. It is widely used in hospitals, food processing, mines and other places where dust-proof and bacteria proof are needed. The anti-inflammatory and analgesic film made of the product after special treatment has good permeability, no toxic side effects, and is easy to use, SMS products compounded with spunbond are widely used in the production of surgical clothes, hats and other sanitary products.
3. Liquid filter material and battery separator: polypropylene melt blown cloth has excellent performance in filtering acid and alkaline liquid, oil, etc. it has been regarded as a good separator material by the battery industry at home and abroad, and has been widely used, which not only reduces the cost of battery, simplifies the process, but also greatly reduces the weight and volume of battery.
4. Oil absorption materials and industrial wipes: all kinds of oil absorption materials made of polypropylene melt blown cloth, with oil absorption capacity up to 14-15 times of self weight, are widely used in environmental protection engineering and oil-water separation engineering. In addition, they can be used as clean materials for oil and dust in industrial production. These applications give full play to the characteristics of polypropylene itself and the adsorption of ultrafine fibers made by melt spraying.
5. Thermal insulation material: the average diameter of the meltblown fiber is between 0.5-5 μ m, which is directly made into nonwovens by randomly laying nets. Therefore, the specific surface area of the melt blown fiber is large and the porosity is high. A large amount of air is stored in this structure, which can effectively prevent the heat loss. It is an excellent filtering and thermal insulation material. It is widely used in the production of clothing and various thermal insulation materials. Such as leather jacket, ski shirt, cold suit, cotton cloth, etc., it has the advantages of light weight, warm keeping, no moisture absorption, good air permeability, no rot, etc.
