Melt-blown line profile:
The raw material used in melt-blow equipment production is slicing, which is generally polypropylene and polyester, as well as polyamide, polyetherketone ketone etc. However, they adopt the same principle, which is that polymerized substance is squeezed through spinneret orifice in melting state, and becomes microfiber after the impact of high-speed hot air. 

The daily production equipment: 6000to6500 PCS / 24 h/day (daily maximum yield Φ28 x 63.5mm（±1.5）x 250mm、135g) depends on raw material, product specifications and environment temperature! Maximum yield extruder: 35 kg x 24 h/day = 850 kg/day .wastage≤5%.


Electric cabinet:
Electrical machine is controlled by ABB frequency inverter ,the host heating zone are controlled by japanese RKC temperature-control table ,the metering pump motor is controlled by Japanese Fuji or Japan's Mitsubishi inverter control, other electrical control has a domestic first-class control (such as relay ,button, pilot lamp, wire, etc.)



Electric furnace
Used for calcining spinneret, the residual polymer in the spinneret carbonization to clean the spinneret.

Spinning trunk:
The effect of spinning trunk is to promote the chain breakage of polymerized substance melting. Also material has the same flow path and heat energy absorption in the spinning trunk. Finally, die head is squeezed by metering pump in constant quantification. In the whole spinning trunk, metering pump is one of the important compositions.

Metering pump: the high-precision building-block used in chemical fiber production.

Effect: accurately measure, continuously convey melt mass of fibering high polymer, and produce the preset pressure to maintain the spinning melt mass overcome the resistance of spinning components or spinning jet.

Spinning jet: the internal has two parts of air channel and material channel (spinneret orifice).   The top and bottom of material channel both have air channels, and there is a 60° angel between air channel and material channel, making the two airflow collide and form turbulence, impelling the melting polymerized substance squeezed by material channel to become fibre. 






Extruder:

Operating principle: material enters into the flight channel of screw from charge door. As the rotation of screw pushes the slicing forwards, making the slicing constantly absorb heat energy provided by heating installation. On the other hand, due to the shearing action between slicing and slicing, slicing and screw, sleeve frictions, and liquid layers, part of mechanical energy is converted to heat energy. During the ongoing process, slicing is gradually melted as melt mass as the temperature goes higher and higher. During the melting process, polymerized substance takes changes in temperature, pressure, viscosity and form, etc. It transforms from solid state (vitreous state) to elastomeric state. With the higher temperature, it appears plastic flowage, and becomes viscous flow state. The polymerized substance of viscous flow state is transmitted to melt mass pipes with certain pressure through screw’s propulsion and screw exit’s resistance.


Effect of screw extruder: squeeze, exhaust, melting and mixed homogenization of solid high polymer are conducted under constant temperature and pressure to quantitatively output high polymer melt mass.

Advantages of screw extruder: ① fast in melting. ② intense mechanical shearing. ③continuous renewal of heat exchange surfaces, more suitable for material with high viscosity.  ④convenient output adjustment. 

Composition of screw extruder: ① melting extrusion device: Screw, sleeve. ② heating and cooling system: Cast-aluminum sleeve heater and water cooling jacket. ③ drive system: Variable speed electric motor and variable speed gearbox.


 Extruder quick coupling device:
 It is the equipment used to filtrate the melted polymerized substance, which internal has a round groove to put filtering net. The filtering net should be changed promptly (depending on extruder pressure) 


Receiving device:
By a motor drives the optic axis and screw axis respectively, through the optical axis and screw shaft speed difference between stripping





Automatic cutting device:
 Controlled by time and air pressure. Gas-tightness should be checked before utilization, and debugged to a normal state.




Filter:
PP filter is produced by way of polyropylene melt,the micron number by 1um to 100um.The filter haven't inner punch spindle and used dense thin outside in design,can maintain the stability of the flow rate and pressure difference and service life.




PP filter form continuous melt-blown filter diameter is fine,general is 5-30UM,the filter mutual tangles,the formation of the aperture is less than 40 microns;but the porosity is very high,generally greater than or equal to 80%,effectively guarantee the filtration precision and flow.the service life is longer:continuous melt-blown filter aperture distribution along the radial gradient.

enough space to accommodate large particles,to ensure that the filter is not blocked by a short time.the inner block tiny particles at the same time ,ensure the filtering precision ,thus greatly improving the service life of the filter ,reduces the cost .

Security:continuous melt-blown filter to polypropylene as raw materials,non-toxic,no smell,in the process of production does not add other chemicals and no other chemical substances generated,can be directly for drinking water and other liquid filtration.

PP filter adaptability: polypropylene filter can  resistant mildew, resistant to acid and alkali, inorganic and organic solvent resistance. At the same time has the characteristics of oil absorption is not bibulous. Filter product USES the non-toxic tasteless polypropylene (material: PP) as raw material, after melting, injection, traction accept forming deep and made of a variety of tubular filter. Fiber in random space form three-dimensional microporous structure, diameter d holes along the filtrate flow gradient distribution of integrating surface, deep and fine fine filter　

Using different production technology of controllable made different filtration precision, also can form inside and outside of the surface of the filter element or the depth of the exterior inside type filter, etc. The filter itself does not use any chemical adhesive, more in line with the health, safety and high quality requirements. Can intercept different particle sizes of impurities. Filter precision range 1 um to 100 um, its flux is 1.5 times more than equal precision filter, can be configured in different types of end cover joint and meet the needs of the various engineering installation. Aperture density, have layers, acid, alkali and other chemicals and organic solvent corrosion, strength is big, price is cheap, conform to the hygiene licensing standards.
