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 alka li 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 melt
blown 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.
