The mixing drying function is to stir, dry and mix PE resin and color masterbatch to get even raw materials.
How is PE pipe produced?
The specific steps of PE pipe production process are as follows:
1, mix dry
The mixing drying function is to stir, dry and mix PE resin and color masterbatch to get even raw materials.
2. Plasticized extrusion
Raw materials from the hopper into the extruder, after transport, compression, melting, homogenization, from the solid particles gradually into high elastic state, and then from the high elastic state gradually into viscous fluid (viscous flow), and continuous extrusion.
3. Mold forming
At the right temperature, the material from the extruder is transferred from rotary motion to linear motion through the filter plate into the mold. After the spiral flow, the forming section is fused and pressed into tubular billet, and finally extruded from the orifice die.
4. Cooling and setting
The heat pipe billet extruded from the mold is shaped and cooled by the vacuum sizing box of the sizing sleeve under the state of negative pressure, and then the inside of the pipe is gradually cooled by the jet cooling box, so as to solidify and finalize the whole.
5, cutting
Under the control of the meter wheel, a planetary cutter is used to finish the fixed-length cutting of pipe.
6. Stack and pack
The cut pipe is pushed to the turntable, inspected and packed before being shipped.
Above is the specific steps in the production of PE pipe, in the production of PE pipe, the above steps are indispensable. However, the following points should be paid attention to during the production operation:
1, feeding machine operation matters needing attention
The suction time should not be too long; Clean the filter screen regularly; Monitor the microswitch for normal operation.
2. Matters needing attention in dryer operation
(1) Turn on the fan first and then turn on the heating.
(2) The best drying effect can be achieved only when the barrel is full.
(3)PE material drying temperature is about 80°C.
(4) The temperature control meter shows the difference of the actual temperature under the set temperature. When the displayed temperature is zero, the actual temperature is consistent with the set temperature.
(5) Working principle of bimetal thermometer: using two kinds of materials with different expansion coefficients, the temperature is measured according to the degree of deformation.
(6) Control the direction of wind flow.
(7) The air inlet shall not be closed.
In general, if you want to produce qualified PE pipe, you need to go through the above production steps and processes of these PE pipes. In addition, each enterprise can also according to their own actual situation to optimize their production popular, so that the PE pipe pipe production quality to achieve the best. Poly PE pipe simplifies the original production process, the implementation of their own research and development of the production process, so that the production of PE pipe pipe quality is better than other brands of PE pipe pipe.
