NovaStar, NN147, Polypropylene Meltblown Nonwoven Line, 1600mm Width, 10 to 80 g/m2 (New)

NovaStar, NN147, Polypropylene Meltblown Nonwoven Line, 1600mm Width, 10 to 80 g/m2

Description

  1. Overview
    1. Melt-spray non-woven fabric is one of the fastest developing non-woven fabrics and is known as the shortest one-step polymer production process in the world.
    2. Its products have high filtering efficiency, low resistance, softness, and a network that can knot and adhere, among many other advantages.
    3. Main uses include air filtration, acid liquid filtration, food hygiene, industrial dust mask making, health care products, industrial precision wipes, heat preservation material, oil absorption material, battery separator, and imitation leather base cloth.
    4. In many respects, its performance is superior to similar products of traditional textiles.
    5. With the development of post-processing technology, the application of melt-spray non-woven fabrics will be more extensive.
    6. The quality and energy consumption of the production lines with various widths are close to the advanced level of similar foreign products.
  2. Features
    1. Special hanger type and gas equal-pressure spinning die head with independent intellectual property rights are incorporated to ensure uniform melt distribution.
    2. The air nozzle pressure is stable, the air flow on both sides is symmetrical, and the air flow in the direction of width is uniform.
    3. Easy adjustment of air gap width.
    4. Incorporating the specially designed hot gas flow heating device, it has good heating efficiency and excellent heat exchange efficiency and energy consumption is low.
    5. The receiving distance can be adjusted, and the receiving form (flat screen receiving and drum receiving) can be easily replaced.
    6. Fiber fineness and cloth surface uniformity.
    7. Standing-polarization treatment makes melting spray cloth have good filtering effect.
  3. Common Application Fields
    1. Application in the field of air purification: used in air purifiers as sub-high-efficiency and high-efficiency air filter elements and for coarse and medium efficiency air filtration with large flow rates; has advantages of low resistance, high strength, excellent acid and alkaline resistance, corrosion resistance, stable efficiency, long service life, and low price; no short fleecy phenomenon of filter material falling off in the purified gas.
    2. Application in the field of medical and health care: made of melt-blown cloth, dust mouth breathing resistance is small, not short, dust efficiency of 99%; widely used in hospitals, food processing, mining, and other workplaces to dust; prevent bacteria with anti-inflammatory analgesic membrane made of product after special treatment, permeability is good, non-toxic side effects, easy to use; spun-bonded fabric of SMS composite products are widely used in the production of sanitary products such as surgical clothes.
    3. Liquid filtration materials and battery diaphragm: polypropylene melt-blown filter cloth used in acidic and alkaline liquid, oil, and oil has very excellent performance; regarded as a good membrane material in the battery industry and has been widely used, not only reducing the cost of battery but also simplifying the process and greatly reducing the weight and volume of the battery.
    4. Oil-absorbing materials and industrial rubbing cloth: all kinds of oil-absorbing materials made of polypropylene melting and spraying cloth, with oil-absorbing capacity up to 14 to 15 times of its own weight; widely used in environmental protection engineering and oil-water separation engineering; can be used as clean materials of oil and dust in industrial production; these applications give full play to the properties of polypropylene itself and the absorbability of the ultrafine fiber produced by melting and spraying.
    5. Thermal insulation materials: the average diameter of molten shotcrete ultrafine fiber is between 500 and 5000 mm, with large specific surface area, and a large amount of micro pores are formed in the cloth with high porosity; this structure stores a large amount of air, can effectively prevent heat loss, has excellent heat preservation; widely used in the production of clothing and a variety of thermal insulation materials such as leather jacket, ski jacket, cold clothing, cotton village cloth, with light, warm, moisture absorption, good air permeability, no mildew, and other advantages.
  4. N95 / Medical / Civil Mask Material M Melt-Blown Nonwovens Product Introduction
    1. Masks, whose raw materials are all polypropylene (PP), medical surgical masks are generally of multi-layer structure.
    2. The S in the mask layer represents the spunbonded fiber; the diameter of the fiber is relatively thick, about 20 microns, and the 2 layers are mainly spunbonded fibers supporting the whole non-woven fabric structure with no obvious effect on the barrier property.
    3. The most important layer inside the mask is the barrier layer or molten spray layer (M); the fiber diameter of the molten spray layer is relatively thin, about 2 microns, so it is only one tenth of the diameter of the spunbonded layer, which is beneficial to preventing bacteria and blood from entering the spunbonded layer.
    4. For fibers spun to the bonding layer, the spray layer M compares the shape of the fibers to the hair; the hair is 1/3 of the diameter, close to the spinning bonding layer, and 1/30 of the diameter of the hair, close to the M fiber diameter; finer fibers are also being developed to ensure better antibacterial barrier performance.
    5. The thinner the M layer, the more it can prevent the entry of small particles such as bacteria; for example, N95 means it can block 95% of small particles (0.3 microns) under normal conditions, according to the national standard GB/T 19083 for medical respirators, in gas flow at 85 L/min conditions.
    6. The N95 is actually a 5-layer mask made of polypropylene nonwoven fabric SMMMS that filters 95 percent of fine particles.
