Spinning machine for spinning polyester and polyamide and polypropylene. Characteristics of melt trickle cold case of solidification fiber, cold air is the high efficiency filter, regulating valve, a flow guide device uniformly blow to trickle. Spinning speed is high, the general is 1500 ~ 600 m / min. Melt spinning machine also has two kinds.
1. Filament spinning machine: polymer chips from the bucket into a screw extruder was melting and by the screw propulsion through the catheter into the spinning box. Melt in the box body by spinning metering pump conveying to the spray silk head (plate), extruded from the spinneret melt trickle in spinning window encounter cold air for cooling and solidification of the fiber and oil by winding winding mechanism on the bobbin. The number of holes in the filament is generally a few holes to a few tens of holes. Spinning cord up to 200 holes, spinning monofilament only one hole, then melt trickle by water cooling. In general, the production of silk spinning melt spun filament spinning machine in the 1970s the trend is: long spinning, each part is equipped with 2, 3, 4, 6 or more spray head, in order to increase the machine; high speed spinning, spinning speed of 3500 ~ 4000 meters per minute, or even as high as 5000 m / min above; jumbo roll, each a bobbin coil loading capacity of up to 10 kg to tens of kilograms; continuous, spinning and stretching in a spinning machine at the same time to complete, the spinning and stretching, deforming process in a spinning machine (BCF production) in polypropylene and nylon production has been applied to. This machine has compact structure, small footprint and high production efficiency. In addition, the degree of automation of the spinning machine is also increasing.
II staple fibre spinning machine with filament spinning machine compared, its characteristics is using porous number of spinneret, usually the number of holes for 400 to 1100, has now developed for porous spinning, hole number up to 4000; in spinning corridor in the annular blowing or ring blowing and the quench air cooling blower system, each spinning position does not have a separate winding mechanism, each part of the silk a by guide wire plate or small rotor, by the traction machine will lead the tow wire feeding wheel, then the tow placement in the silk holding bucket. The capacity of a barrel can reach 450 to 2000 kg. Direct spinning method is often used in the production of large synthetic fiber factory. The melt spinning compact spinning machine without spinning stack.
Among them, the ZIF-8/PDMS mixed matrix membranes combined with the advantage of inorganic particles and an organic polymer, improves the membrane gas separation performance, it has good development potential in the separation of hydrocarbon gases and organic vapors recovery applications; high performance resistance to CO2 multi-channel mixed conductor in hollow fiber oxygen permeable membrane can be used for oxygen separation, oxygen enriched combustion, low carbon hydrocarbon partial oxidation reaction, in the field of energy and environment has a very attractive prospect.
In recent years, the discharge of oily wastewater and oil leakage to the community and the environment has brought a great threat to the traditional oil and water separation materials can not meet the needs of the membrane separation method as a separation efficiency is high, the new oil water separation method is concerned.
Small spinning machine in the work, the application is wide, generally can be used as a laboratory equipment, I believe that we have some understanding of the use of it, then the following introduction of the application of small - sized spinning machine specific what?
1, can simulate the production process, process simulation, color, etc., all the use of variable frequency speed control mode;
2, used for scientific research, testing and testing;
3, the production equipment can be spun FDY fiber samples;
4, hot roller with special permanent magnet synchronous motor drive; spinning machine
