Detailed description of the invention
Fig. 1 is process flow chart of the invention；
Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below
The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.
Referring to Fig. 1, the preferred embodiment of the present invention provides a kind of production technology of PE tubing, comprising the following steps:
A, raw material is matched according to following parts by weight: 100 parts of PE raw material, 0 part of polyamide 6, female 20 parts of colorant, steady
Determine 3 parts of agent, 2 parts of antioxidant, 2 parts of defoaming agent；It is poured into after the completion of the raw material proportioning in dry mixed machine, the drying is mixed
It is sufficiently dry to remove the moisture in each raw material that conjunction machine uses air-dried mode to carry out the raw material, and makes after thorough mix-ing
Raw material enters the hopper of forced-feeding device, the time that raw material mixes in the dry mixed machine under the action of by air blower
For 4-8min, the time that raw material mixes in dry mixed machine in actual operation is mostly 6min；
B, the auger of the hopper by after drying mixed raw material be sent into forced-feeding device, forced-feeding device it is main
Effect is that conveyance conduit is made to expect to fill up enough, keeps subsequent extrusion device wire vent more uniform, and the temperature of forced-feeding device is 130
DEG C -140 DEG C, mixed raw material enters vented twin screw extrusion device under the action of forced-feeding device, and vented twin screw squeezes out
The temperature of device is 180 DEG C -200 DEG C, and the temperature of forced-feeding device is 135 DEG C in specific implementation, and vented twin screw squeezes out
When the temperature of device is 190 DEG C, what is formed under the collective effect of forced-feeding device and the vented twin screw extrusion device is molten
Body is more suitable the profile of production PE pipe, and waste gas recovery processing unit squeezes the forced-feeding device and the vented twin screw
The exhaust gas of device is recycled out, since waste gas recovery processing unit is vacuum waste gas recovery processing unit, so forcing
Exhaust gas in drawing-in device and vented twin screw extrusion device is slowly inhaled into waste gas recovery processing dress under the action of vacuum
In setting, by the liquid in waste gas recovery processing unit, (liquid mentioned here refers mainly to the exhaust gas being inhaled under high pressure effect
Water) it absorbs, waste gas recovery processing unit is discharged with liquid in absorbed exhaust gas；
C, raw material enters extrusion die after forming melt, and extrusion die is plasticized melt, and the melt after plasticizing is squeezing out
Profile is formed under the action of die head；
